ansible經常使用模塊

1、ansible經常使用模塊

  模塊是Ansible執行的最小單位,能夠是由Python編寫,也能夠是Shell編寫,也能夠是由其餘語言編寫。html

  1、ping模塊

  測試鏈接可通性,沒有參數。通的話返回pong。node

  一、使用示例

ansible all -m ping 
    一、可通,返回pong以下圖

    二、不通,返回以下圖

  2、setup模塊

  主要用於獲取主機信息,在playbooks裏常常會用到的一個參數gather_facts就與該模塊相關。setup模塊下常用的一個參數是filter參數,具體使用示例以下(因爲輸出結果較多,這裏只列命令不寫結果)python

  每一個被管理節點在接收並運行管理命令以前,會將本身主機相關信息(如系統版本,主機IP地址)告知ansible管理主機mysql

  一、幫助信息

ansible-doc -s setup
--tree :將全部主機的輸出信息保存到/tmp/目錄下,以/etc/ansible/hosts裏的主機名爲文件名
ansible all -m setup -a 'filter=ansible_distribution_version' --tree /tmp/

filter :過濾關鍵字
#ansible db -m setup -a 'filter=ansible_distribution_version'

gather_subset:按子集收集信息,值有all, min, hardware, network, virtual, ohai, facter。不包含請使用!號,如,!network

  二、常常獲取的信息,統計表格以下

關鍵字 說明 返回值例子
ansible_nodename 節點名 "6-dns-1.hunk.tech"

  3、command模塊

  command 命令模塊,默認模塊(可省略),用於在遠程執行命令(不能使用變量)nginx

  一、幫助信息

1 creates:一個文件名,當該文件存在,則該命令不執行 
2 free_form:要執行的linux指令 
3 chdir:在執行指令以前,先切換到該指定的目錄 
4 removes:一個文件名,當該文件不存在,則該選項不執行
5 executable:切換shell來執行指令,該執行路徑必須是一個絕對路徑

  二、使用範例

# ansible all -a 'date'

  

  4、cron模塊

  cron 定時任務模塊git

  一、幫助信息

# ansible-doc -s cron
- name: Manage cron.d and crontab entries
  cron:
      backup:                # If set, create a backup of the crontab before it is modified. The location of the backup is returned in
                               the `backup_file' variable by this module.
      cron_file:             # If specified, uses this file instead of an individual user's crontab. If this is a relative path, it is
                               interpreted with respect to /etc/cron.d. (If it is absolute, it will
                               typically be /etc/crontab). Many linux distros expect (and some require)
                               the filename portion to consist solely of upper- and lower-case letters,
                               digits, underscores, and hyphens. To use the `cron_file' parameter you
                               must specify the `user' as well.
      day:                   # Day of the month the job should run ( 1-31, *, */2, etc )
      disabled:              # If the job should be disabled (commented out) in the crontab. Only has effect if `state=present'.
      env:                   # If set, manages a crontab's environment variable. New variables are added on top of crontab. "name" and
                               "value" parameters are the name and the value of environment variable.
      hour:                  # Hour when the job should run ( 0-23, *, */2, etc )
      insertafter:           # Used with `state=present' and `env'. If specified, the environment variable will be inserted after the
                               declaration of specified environment variable.
      insertbefore:          # Used with `state=present' and `env'. If specified, the environment variable will be inserted before the
                               declaration of specified environment variable.
      job:                   # The command to execute or, if env is set, the value of environment variable. The command should not
                               contain line breaks. Required if state=present.
      minute:                # Minute when the job should run ( 0-59, *, */2, etc )
      month:                 # Month of the year the job should run ( 1-12, *, */2, etc )
      name:                  # Description of a crontab entry or, if env is set, the name of environment variable. Required if
                               state=absent. Note that if name is not set and state=present, then a new
                               crontab entry will always be created, regardless of existing ones.
      reboot:                # If the job should be run at reboot. This option is deprecated. Users should use special_time.
      special_time:          # Special time specification nickname.
      state:                 # Whether to ensure the job or environment variable is present(安裝) or absent(卸載).
      user:                  # The specific user whose crontab should be modified.
      weekday:               # Day of the week that the job should run ( 0-6 for Sunday-Saturday, *, etc )
ansible-doc -s cron
 1 backup:對遠程主機上的原任務計劃內容修改以前作備份 
 2 cron_file:若是指定該選項,則用該文件替換遠程主機上的cron.d目錄下的用戶的任務計劃 
 3 day:日(1-31,*,*/2,……) 
 4 hour:小時(0-23,*,*/2,……)  
 5 minute:分鐘(0-59,*,*/2,……) 
 6 month:月(1-12,*,*/2,……) 
 7 weekday:周(0-7,*,……)
 8 job:要執行的任務,依賴於state=present 
 9 name:該任務的描述 
10 special_time:指定何時執行,參數:reboot,yearly,annually,monthly,weekly,daily,hourly 
11 state:確認該任務計劃是建立仍是刪除 
12 user:以哪一個用戶的身份執行

  二、使用說明

ansible db -m cron -a 'minute=""  hour="" day="" month="" weekday="" job="" name="(必須填寫)" state=

    一、定時設置指定值的寫入便可,沒有設置的能夠不寫(默認是*)web

    二、name必須寫redis

    三、state有兩個狀態:present(添加(默認值))or absent(移除)sql

  三、使用範例

    一、添加定時任務
ansible db -m cron -a 'minute="*/10" job="/bin/echo hello" name="test cron job" state="present"'
ansible db -a "crontab -l"

  結果以下圖

    二、移除定時任務
ansible db -m cron -a 'minute="*/10" job="/bin/echo hello" name="test cron job" state="absent"'
ansible db -a "crontab -l"

  結果以下圖

  5、user/group模塊

  user模塊是請求的是useradd, userdel, usermod三個指令,goup模塊請求的是groupadd, groupdel, groupmod 三個指令。

  一、幫助信息

    一、英文
# ansible-doc -s user
- name: Manage user accounts
  user:
      append:                # If `yes', add the user to the groups specified in
                               `groups'. If `no', user
                               will only be added to
                               the groups specified in
                               `groups', removing them
                               from all other groups.
      comment:               # Optionally sets the description (aka `GECOS') of user
                               account.
      create_home:           # Unless set to `no', a home directory will be made for
                               the user when the
                               account is created or if
                               the home directory does
                               not exist. Changed from
                               `createhome' to
                               `create_home' in version
                               2.5.
      expires:               # An expiry time for the user in epoch, it will be
                               ignored on platforms
                               that do not support
                               this. Currently
                               supported on GNU/Linux,
                               FreeBSD, and
                               DragonFlyBSD. Since
                               version 2.6 you can
                               remove the expiry time
                               specify a negative
                               value. Currently
                               supported on GNU/Linux
                               and FreeBSD.
      force:                 # This only affects `state=absent', it forces removal of
                               the user and associated
                               directories on supported
                               platforms. The behavior
                               is the same as `userdel
                               --force', check the man
                               page for `userdel' on
                               your system for details
                               and support.
      generate_ssh_key:      # Whether to generate a SSH key for the user in question.
                               This will *not*
                               overwrite an existing
                               SSH key.
      group:                 # Optionally sets the user's primary group (takes a group
                               name).
      groups:                # List of groups user will be added to. When set to an
                               empty string `''',
                               `null', or `~', the user
                               is removed from all
                               groups except the
                               primary group. (`~'
                               means `null' in YAML)
                               Before version 2.3, the
                               only input format
                               allowed was a comma
                               separated string. Now
                               this parameter accepts a
                               list as well as a comma
                               separated string.
      hidden:                # Darwin/OS X only, optionally hide the user from the
                               login window and system
                               preferences. The default
                               will be 'True' if the
                               `system' option is used.
      home:                  # Optionally set the user's home directory.
      local:                 # Forces the use of "local" command alternatives on
                               platforms that implement
                               it. This is useful in
                               environments that use
                               centralized
                               authentification when
                               you want to manipulate
                               the local users. I.E. it
                               uses `luseradd` instead
                               of `useradd`. This
                               requires that these
                               commands exist on the
                               targeted host, otherwise
                               it will be a fatal
                               error.
      login_class:           # Optionally sets the user's login class, a feature of
                               most BSD OSs.
      move_home:             # If set to `yes' when used with `home=', attempt to move
                               the user's old home
                               directory to the
                               specified directory if
                               it isn't there already
                               and the old home exists.
      name:                  # (required) Name of the user to create, remove or
                               modify.
      non_unique:            # Optionally when used with the -u option, this option
                               allows to change the
                               user ID to a non-unique
                               value.
      password:              # Optionally set the user's password to this crypted
                               value. On Darwin/OS X
                               systems, this value has
                               to be cleartext. Beware
                               of security issues. See

                               other methods. This
                               option does not disable
                               the user, only lock the
                               password. Do not change
                               the password in the same
                               task. Currently
                               supported on Linux,
                               FreeBSD, DragonFlyBSD,
                               NetBSD.

                               with the user. The
                               behavior is the same as
                               `userdel --remove',

                               2.5, the default shell
                               for non-system users on
                               Mac OS X is /bin/bash.
      skeleton:              # Optionally set a home skeleton directory. Requires
                               create_home option!
      ssh_key_bits:          # Optionally specify number of bits in SSH key to create.
      ssh_key_comment:       # Optionally define the comment for the SSH key.
      ssh_key_file:          # Optionally specify the SSH key filename. If this is a
                               relative filename then
                               it will be relative to
                               the user's home
                               directory.
      ssh_key_passphrase:    # Set a passphrase for the SSH key.  If no passphrase is
                               provided, the SSH key
                               will default to having
                               no passphrase.
      ssh_key_type:          # Optionally specify the type of SSH key to generate.
                               Available SSH key types
                               will depend on
                               implementation present
                               on target host.
      state:                 # Whether the account should exist or not, taking action
                               if the state is
                               different from what is
                               stated.
      system:                # When creating an account `state=present', setting this
                               to `yes' makes the user
                               a system account. This
                               setting cannot be
                               changed on existing
                               users.
      uid:                   # Optionally sets the `UID' of the user.
      update_password:       # `always' will update passwords if they differ.
                               `on_create' will only
                               set the password for
                               newly created users.
ansible-doc -s user
    二、中文
groups:指定用戶的屬組
uid:指定用的uid
password:爲用戶設置登錄密碼,此密碼是明文密碼加密後的密碼
update_password:always/on_create
    always:只有當密碼不相同時纔會更新密碼(默認)
    on_create:只爲新用戶設置密碼
name:指定用戶名
createhome:是否建立家目錄 yes|no(默認是yes)
system:是否爲系統用戶
remove:當state=absent時,remove=yes則表示連同家目錄一塊兒刪除,等價於userdel -r(默認是no)
state:是建立仍是刪除 present(添加(默認值))or absent(移除)
shell:指定用戶的shell環境
append:yes/no
    yes:增量添加group
    no:全量變動group,只設置groups指定的group組(默認)
expires:設置用戶的過時時間,值是一個時間戳
    三、注意事項

  注:指定password參數時,不能使用後面這一串密碼會被直接傳送到被管理主機的/etc/shadow文件中,因此須要先將密碼字符串進行加密處理。而後將獲得的字符串放到password中便可。

    範例

- user: name=johnd comment="John Doe" uid=1040 group=admin
- user: name=james shell=/bin/bash groups=admins,developers append=yes
- user: name=johnd state=absent remove=yes
- user: name=james18 shell=/bin/zsh groups=developers expires=1422403387
#生成密鑰時,只會生成公鑰文件和私鑰文件,和直接使用ssh-keygen指令效果相同,不會生成authorized_keys文件。
- user: name=test generate_ssh_key=yes ssh_key_bits=2048 ssh_key_file=.ssh/id_rsa

  二、生成加密的密碼

  批量建立用戶並設置密碼:https://cloud.tencent.com/info/c23babde3ad9ff6bde07c532a6afa1d0.html

    一、安裝python-pip,並安裝加密函數庫-passlib
yum -y install python-pip
pip install --upgrade pip
pip install passlib 
    二、使用加密函數庫,獲取密文密碼
#  python -c "from passlib.hash import sha512_crypt; import getpass; print(sha512_crypt.using(rounds=5000).hash(getpass.getpass()))"
Password: 
$6$0lwTSmqKOkL.ktgl$OnBexXC7haBf0FRHVMIZM2edDeFWBbpKJ2r9cxVwNvY.vh3IIUzwFz8n7jFglc0CrtQSY12ziDonVL6e71Og2.
    三、建立一個系統用戶,指定用戶密碼
ansible db -m user -a 'name="testops" password="$6$0lwTSmqKOkL.ktgl$OnBexXC7haBf0FRHVMIZM2edDeFWBbpKJ2r9cxVwNvY.vh3IIUzwFz8n7jFglc0CrtQSY12ziDonVL6e71Og2."'
    四、查看測試

  咱們能夠看到被管理主機已建立用戶"testops",而且密碼爲密文已寫入"/etc/shadow"用戶文件中,嘗試用ssh命令使用testops用戶登陸被管理主機,登陸成功!

ansible db -m shell -a "cat /etc/shadow|grep testops"
ssh testops@10.0.0.13

  三、使用範例

    一、添加用戶並設置密碼(加密過程如上)
ansible db -m user -a 'name="testops" password="$6$0lwTSmqKOkL.ktgl$OnBexXC7haBf0FRHVMIZM2edDeFWBbpKJ2r9cxVwNvY.vh3IIUzwFz8n7jFglc0CrtQSY12ziDonVL6e71Og2."'

  結果以下圖

    二、刪除用戶(連通家目錄一併刪除)
ansible db -m user -a 'name="testops" state="absent" remove="yes"'

   注意該用戶下不能有任何進程,不然會報錯以下紅色部分

  6、copy模塊

  複製文件

  一、幫助信息

1 backup:在覆蓋以前將原文件備份,備份文件包含時間信息。有兩個選項:yes|no 
2 content:用於替代"src",能夠直接設定指定文件的值 
3 dest:必選項。要將源文件複製到的遠程主機的絕對路徑,若是源文件是一個目錄,那麼該路徑也必須是個目錄 4 directory_mode:遞歸的設定目錄的權限,默認爲系統默認權限
5 force:若是目標主機包含該文件,但內容不一樣,若是設置爲yes,則強制覆蓋,若是爲no,則只有當目標主機的目標位置不存在該文件時,才複製。默認爲yes
6 others:全部的file模塊裏的選項均可以在這裏使用
7 src:要複製到遠程主機的文件在本地的地址,能夠是絕對路徑,也能夠是相對路徑。若是路徑是一個目錄,它將遞歸複製。在這種狀況下,若是路徑使用"/"來結尾,則只複製目錄裏的內容,若是沒有使用"/"來結尾,則包含目錄在內的整個內容所有複製,相似於rsync。 
8 validate :The validation command to run before copying into place. The path to the file to validate is passed in via '%s' which must be present as in the visudo example below.

  二、使用範例

    一、使用src
ansible db -m copy -a 'src=/etc/hosts dest=/tmp/ owner=root mode=640 backup=no'

  結果以下圖

    二、使用content 
ansible db -m copy -a 'content="Hello ansible\n you are clever!\n" dest=/tmp/ansile.txt owner=root mode=640 backup=no'

ansible db -m copy -a 'content="Hello ansible\nyou are clever!\n" dest=/tmp/ansile.txt force=yes owner=root mode=640 backup=no'

  管理機操做結果以下圖

  目標主機結果以下圖

  7、file模塊

  設定文件屬性和建立文件的符號連接

  一、幫助信息

1 force:須要在兩種狀況下強制建立軟連接,一種是源文件不存在但以後會創建的狀況下;另外一種是目標軟連接已存在,須要先取消以前的軟鏈,而後建立新的軟鏈,有兩個選項:yes|no 
2 group:定義文件/目錄的屬組 
3 mode:定義文件/目錄的權限
4 owner:定義文件/目錄的屬主
5 path:必選項,定義文件/目錄的路徑
6 recurse:遞歸的設置文件的屬性,只對目錄有效
7 src:要被連接的源文件的路徑,只應用於state=link的狀況
8 dest:被連接到的路徑,只應用於state=link的狀況 
9 state:  directory:若是目錄不存在,建立目錄 file:即便文件不存在,也不會被建立 link:建立軟連接 hard:建立硬連接 touch:若是文件不存在,則會建立一個新的文件,若是文件或目錄已存在,則更新其最後修改時間 absent:刪除目錄、文件或者取消連接文件

   二、使用範例

ansible db -m file -a "src=/etc/fstab dest=/tmp/fstab state=link"
ansible db -m file -a "path=/tmp/fstab state=absent"
ansible db -m file -a "path=/tmp/test state=touch"

  安裝程序包

  一、幫助信息

1 config_file:yum的配置文件 
2 disable_gpg_check:關閉gpg_check 
3 disablerepo:不啓用某個源 
4 enablerepo:啓用某個源
5 name:要進行操做的軟件包的名字,也能夠傳遞一個url或者一個本地的rpm包的路徑 
6 state:狀態(present安裝,absent卸載,latest最新)

  二、使用示例

    一、安裝zsh
ansible web -m yum -a 'name=httpd state=latest'
ansible web -m yum -a 'name="@Development tools" state=present'
ansible web -m yum -a 'name=http://nginx.org/packages/centos/6/noarch/RPMS/nginx-release-centos-6-0.el6.ngx.noarch.rpm state=present'

  目標主機驗證

# rpm  -q zsh
zsh-5.0.2-28.el7.x86_64
  二、卸載
ansible web -m yum -a 'name=zsh state=absent'

  目標主機驗證

# rpm  -q zsh
package zsh is not installed 

  9、service模塊

  一、幫助信息

1 arguments:給命令行提供一些選項 
2 enabled:是否開機啓動 yes|no
3 name:必選項,服務名稱 
4 pattern:定義一個模式,若是經過status指令來查看服務的狀態時,沒有響應,就會經過ps指令在進程中根據該模式進行查找,若是匹配到,則認爲該服務依然在運行
5 runlevel:運行級別
6 sleep:若是執行了restarted,在則stop和start之間沉睡幾秒鐘
7 state:對當前服務執行啓動,中止、重啓、從新加載等操做(started,stopped,restarted,reloaded)

   二、使用示例

    一、保持服務啓動並設置爲開機自啓
 ansible web -m service -a 'enabled=yes name=httpd state=started'

    二、查看服務狀態
ansible web -a 'service httpd status'

#centOS7.x以前

  shell:
      chdir:                 # cd into this directory before running the command
      creates:               # a filename, when it already exists, this step will *not* be run.
      executable:            # change the shell used to execute the command. Should be an absolute path to the executable.
      free_form:             # (required) The shell module takes a free form command to run, as a string.  There's not an actual option named "free form".  See the
                               examples!
      removes:               # a filename, when it does not exist, this step will *not* be run.
      stdin:                 # Set the stdin of the command directly to the specified value.
      warn:                  # if command warnings are on in ansible.cfg, do not warn about this particular line if set to no/false.
ansible-doc -s shell

  二、使用範例

  使用command模塊會報錯,沒法獲得想要的結果。

ansible web -m shell -a "ps -ef|grep httpd"

  11、script模塊

  將本地腳本複製到遠程主機,並執行。

  一、幫助信息

ansible-doc -s script
- name: Runs a local script on a remote node after transferring it
  script:
      chdir:                 # cd into this directory on the remote node before running the script
      creates:               # a filename, when it already exists, this step will *not* be run.
      decrypt:               # This option controls the autodecryption of source files using vault.
      executable:            # Name or path of a executable to invoke the script with
      free_form:             # (required) Path to the local script file followed by optional arguments. There is no parameter actually named 'free form'; see the
                               examples!
      removes:               # a filename, when it does not exist, this step will *not* be run.

 8 dirs:傳速目錄不進行遞歸,默認爲no,即進行目錄遞歸
 9 rsync_opts:rsync參數部分
10 set_remote_user:主要用於/etc/ansible/hosts中定義或默認使用的用戶與rsync使用的用戶不一樣的狀況
11 mode: push或pull 模塊,push模的話,通常用於從本機向遠程主機上傳文件,pull 模式用於從遠程主機上取文件

  二、使用範例
