saltstack實戰4--綜合練習1
規範配置管理
實際工做中可能會有現網環境，基線環境，開發環境。 須要使用saltstack統一管理。機器多了，業務多了，可能配置文件存放的會比較亂，所以能夠統一管理起來apache
咱們能夠再加2個目錄，test是測試環境，prod是生產環境，base是基線環境。
操做以下，新添加2個目錄，同時調整基線目錄
# Example:
# file_roots:
# base:
# - /srv/salt/
# dev:
# - /srv/salt/dev/services
# - /srv/salt/dev/states
# prod:
# - /srv/salt/prod/services
# - /srv/salt/prod/states
#
file_roots:
base:
- /srv/salt/base
test:
- /srv/salt/test
prod:
- /srv/salt/prod
重啓服務讓配置生效，建立目錄，調整原先的配置文件到新的base目錄下vim
[root@master pillar]# /etc/init.d/salt-master restart Stopping salt-master daemon: [ OK ] Starting salt-master daemon: [ OK ] [root@master pillar]# mkdir /srv/salt/base -p [root@master pillar]# mkdir /srv/salt/test -p [root@master pillar]# mkdir /srv/salt/prod -p [root@master pillar]# cd /srv/salt/ [root@master salt]# ls apache.sls base prod test top.sls [root@master salt]# mv apache.sls base/ [root@master salt]# mv top.sls base/ [root@master salt]# ll total 12 drwxr-xr-x 2 root root 4096 Jan 1 19:33 base drwxr-xr-x 2 root root 4096 Jan 1 19:32 prod drwxr-xr-x 2 root root 4096 Jan 1 19:32 test [root@master salt]#
文件管理的練習
對minion的dns文件進行統一管理數組
先在base目錄下建立個files目錄，專門存放文件，這裏給這個dns文件追加個不同的東西，便於標識bash
[root@master salt]# cd /srv/salt/base/ [root@master base]# mkdir files [root@master base]# cd files/ [root@master files]# ls [root@master files]# cp /etc/resolv.conf . [root@master files]# ls resolv.conf [root@master files]# cat resolv.conf # Generated by NetworkManager nameserver 10.0.1.11 [root@master files]# echo "#create by zyx" >> resolv.conf [root@master files]# cat resolv.conf # Generated by NetworkManager nameserver 10.0.1.11 #create by zyx [root@master files]#
編輯配置文件，用於管理這個dns文件給minion，須要進行一些配置，存放的路徑，來源，權限，數組等 服務器
注意下面兩種寫法等價的 app
[root@master files]# cd ..
[root@master base]# pwd
/srv/salt/base
[root@master base]# vim dns.sls
[root@master base]# cat dns.sls
/etc/resolv.conf:
file.managed:
- source: salt://files/resolv.conf
- user: root
- group: root
- mode: 644
[root@master base]#
等價於下面的，默認你沒有定義name的話，salt會把id當成name的默認值，下面的resolv-file是個id，隨便定義，只要惟一便可測試
[root@master base]# cat dns.sls
resolv-file:
file.managed:
- source: salt://files/resolv.conf
- name: /etc/resolv.conf
- user: root
- group: root
- mode: 644
[root@master base]#
執行一下，能夠看到Changes的變化的部分ui

之後對現網管理的話，能夠把它們分類，這樣針對哪臺機器須要安裝或者配置什麼東西時，把配置文件include進來便可。下降模塊之間的耦合性。更加靈活和方便
能夠分爲：
系統初始化
功能模塊
業務模塊
另外配置文件中語法格式要嚴格遵照YAML語法規則。
jinja模板的使用
在平常管理中，有時候會遇到這種狀況，對A機器某個文件管理，好比此文件中有一處的配置不固定，好比端口號或者IP
A機器多是80端口，可能過幾天須要使用8080端口，而咱們每次去更改源文件比較麻煩，咱們此時能夠經過使用jinja模板把變化的部分用變量代替
而後，在配置管理文件裏面定義此變量的值。
例如，dns服務器的IP常常發生變化。
先修改源文件，把原先的值的部分用變量代替
而後修改配置管理文件，聲明使用jinja模板，同時設置變量的值，以下，爲了加以區分，咱們把dns值設置爲10.0.1.111
[root@master files]# cat resolv.conf
# Generated by NetworkManager
nameserver {{ DNS_SERVER }}
#create by zyx
#third
[root@master files]# pwd
/srv/salt/base/files
[root@master files]# cd ..
[root@master base]# vim dns.sls
[root@master base]# cat dns.sls
/etc/resolv.conf:

- source: salt://files/resolv.conf
- user: root
- group: root
- mode: 644

以上就是配置管理結合jinja的用法
配置管理結合grains和jinja
好比咱們把系統信息加入到minion上
[root@master base]# salt '*' grains.get os
minion01:
CentOS
minion02:
CentOS
[root@master base]#
以下操做，把須要更換的地方寫成jinja模板形式的grains變量，而後執行

配置管理--系統初始化
對於一臺機器的管理，能夠分解爲3部分，從下到上依次爲
系統初始化，功能模塊，業務模塊
再次對咱們的base目錄進行改造
base基礎目錄下，init目錄用於存放系統初始化的東西
在init下面創建files文件夾用於存放源文件類的東西，top.sls入口文件不用動，它須要在base目錄下
[root@master base]# cd /srv/salt/base/ [root@master base]# ls apache.sls dns.sls files top.sls [root@master base]# mkdir init [root@master base]# mv dns.sls init/ [root@master base]# mv files/ init/ [root@master base]# ls apache.sls init top.sls [root@master base]# mv apache.sls init/ [root@master base]# ls init top.sls [root@master base]# tree
一、配置好dns相關的東西
[root@master init]# rm -f apache.sls
[root@master init]# ls
dns.sls files
[root@master init]# vim dns.sls
[root@master init]# cat dns.sls
/etc/resolv.conf:
file.managed:
- source: salt://init/files/resolv.conf
- user: root
- group: root
- mode: 644
[root@master init]# vim files/resolv.conf
[root@master init]# cat files/resolv.conf
# Generated by NetworkManager
nameserver 10.0.1.11
#create by zyx
[root@master init]# pwd
/srv/salt/base/init
[root@master init]#
二、關於系統初始化，可能咱們還想讓history命令顯示時間和用戶，經過修改環境變量能達到要求
export HISTTIMEFORMAT="%F %T `whoami`"
[root@master init]# history | tail 613 rm -f apache.sls 614 ls 615 vim dns.sls 616 cat dns.sls 617 vim files/resolv.conf 618 cat files/resolv.conf 619 pwd 620 history | tail 621 export HISTTIMEFORMAT="%F %T `whoami` 622 history | tail [root@master init]# export HISTTIMEFORMAT="%F %T `whoami`" [root@master init]# history | tail 615 2017-01-01 21:20:26 root vim dns.sls 616 2017-01-01 21:20:59 root cat dns.sls 617 2017-01-01 21:21:05 root vim files/resolv.conf 618 2017-01-01 21:21:24 root cat files/resolv.conf 619 2017-01-01 21:21:40 root pwd 620 2017-01-01 21:23:11 root history | tail 621 2017-01-01 21:23:14 root export HISTTIMEFORMAT="%F %T `whoami` 622 2017-01-01 21:23:34 root history | tail 623 2017-01-01 21:23:37 root export HISTTIMEFORMAT="%F %T `whoami` " 624 2017-01-01 21:23:39 root history | tail [root@master init]#
咱們把它變成配置文件能夠管理的方式，新建一個sls文件，用於管理歷史命令
[root@master init]# pwd
/srv/salt/base/init
[root@master init]# vim history.sls
[root@master init]# cat history.sls
/etc/profile:
file.append:
- text:
- export HISTTIMEFORMAT="%F %T `whoami`"
[root@master init]#
三、咱們還想記錄日誌：時間，哪一個IP執行的，執行時所在的目錄，執行的命令等都記錄到系統日誌裏面
這裏使用了logger命令
[root@master ~]# logger hehe [root@master ~]# tail -1 /var/log/messages Jan 1 21:35:13 master root: hehe [root@master ~]#
logger命令能把東西記錄到messages裏面
以及系統自帶的變量
[root@master init]# echo $(whoami) root [root@master init]# echo $(who am i) root pts/0 2017-01-01 14:04 (10.0.1.53) [root@master init]#
export PROMPT_COMMAND='{ msg=$(history 1 | { read x y;echo $y; });logger "[euid=$(whoami)]":$(who am i):[`pwd`]"$msg"; }'
[root@master init]# w
21:28:59 up 2 days, 6:24, 2 users, load average: 0.00, 0.00, 0.00

Jan 1 21:29:12 master root: [euid=root]:root pts/0 2017-01-01 14:04 (10.0.1.53):[/srv/salt/base/init]2017-01-01 21:29:12 root w
[root@master init]#
經過配置文件管理，以下書寫
[root@master init]# cat audit.sls
/etc/bashrc:
file.append:
- text:
- export PROMPT_COMMAND='{ msg=$(history 1 | { read x y;echo $y; });logger "[euid=$(whoami)]":$(who am i):[`pwd`]"$msg"; }'
[root@master init]#
如今已經寫了3個用於初始化的腳本
dns.sls
history.sls
audit.sls
四、在寫一個關於修改內核的腳本
saltstack提供了一個改內核參數的模塊，可使用這個模塊配置它
直接vim /etc/sysctl 這個文件不是特別好的方法 由於下面這些機器的好比下面參數是根據本身的內存自動生成的，確定不會是全部機器同樣 直接修改這個文件不是特別好，可是能夠往裏面加東西
saltstack提供了一個改內核參數的模塊，可使用這個模塊配置它
先查看下minion01的內核一些當前信息
[root@master ~]# cat /proc/sys/net/ipv4/ip_local_port_range 32768 61000 [root@master ~]# cat /proc/sys/fs/file-max 199704 [root@master ~]#
在master上編輯一個修改內核參數的配置文件
[root@master init]# cat sysctl.sls
vm.swappiness:
sysctl.present:
- value: 0
net.ipv4.ip_local_port_range:
sysctl.present:
- value: 10000 65000
fs.file-max:
sysctl.present:
- value: 100000
[root@master init]#
五、對以上配置管理文件進行統一管理
再寫個sls，把上面這些文件全包含進去，這樣的好處在於咱們沒必要把全部初始化的文件都寫在一個配置文件裏，不方便管理，耦合性過高也容易出錯
[root@master init]# cat env_init.sls include: - init.dns - init.history - init.audit - init.sysctl [root@master init]# ll total 24 -rw-r--r-- 1 root root 173 Jan 1 21:39 audit.sls -rw-r--r-- 1 root root 131 Jan 1 21:20 dns.sls -rw-r--r-- 1 root root 70 Jan 1 22:00 env_init.sls drwxr-xr-x 2 root root 4096 Jan 1 21:21 files -rw-r--r-- 1 root root 88 Jan 1 21:25 history.sls -rw-r--r-- 1 root root 174 Jan 1 21:55 sysctl.sls [root@master init]#
編輯top.sls文件
[root@master init]# cd ..
[root@master base]# pwd
/srv/salt/base
[root@master base]# ls
init top.sls
[root@master base]# vim top.sls
[root@master base]# cat top.sls
base:
'*':
- init.env_init
[root@master base]#
先模擬執行下，它不會實際執行，可是會檢測一些配置文件語法，以及目錄是否存在，很是推薦
salt '*' state.highstate test=True
以下先測試執行
[root@master base]# salt '*' state.highstate test=True

[root@master base]#
在minion上驗證測試，因爲涉及到環境變量的更改，須要斷開終端從新鏈接
測試沒問題
[root@minion01 ~]# history | tail 293 2017-01-01 22:16:21 rootrpm -qa httpd 294 2017-01-01 22:16:21 rootrpm -qa httpd-devel 295 2017-01-01 22:16:21 rootchkconfig --list httpd 296 2017-01-01 22:16:21 rootps -ef |grep yum 297 2017-01-01 22:16:21 rootps -ef | grep httpd 298 2017-01-01 22:16:21 rootsalt --version 299 2017-01-01 22:16:21 rootsalt-call --version 300 2017-01-01 22:16:21 rootsalt-minion --version 301 2017-01-01 22:16:21 rootcat /etc/resolv.conf 302 2017-01-01 22:16:21 roothistory | tail [root@minion01 ~]# tail -1 /var/log/messages Jan 1 22:16:23 minion01 root: [euid=root]:root pts/0 2017-01-01 22:16 (10.0.1.53):[/root]2017-01-01 22:16:21 roothistory | tail [root@minion01 ~]# cat /proc/sys/net/ipv4/ip_local_port_range 10000 65000 [root@minion01 ~]# cat /proc/sys/fs/file-max 100000 [root@minion01 ~]#
上面內核的修改，不只直接生效了，在配置文件裏也變動了
[root@minion01 ~]# tail -3 /etc/sysctl.conf vm.swappiness = 0 net.ipv4.ip_local_port_range = 10000 65000 fs.file-max = 100000 [root@minion01 ~]# cat /etc/resolv.conf # Generated by NetworkManager nameserver 10.0.1.11 #create by zyx [root@minion01 ~]#
