集羣運維自動化工具ansible之使用playbook安裝zabbix客戶端

以前介紹了關於ansible的安裝與使用（包括模塊與playbook使用，地址是http://www.jb51.net/article/52154.htm），今天介紹一下如何使用playbook來部署zabbix客戶端。
ansible服務端的環境爲centos 6.5 x86_64系統
ansible客戶端環境爲centos 6.3 x86_64系統
目前個人playbook只容許centos或redhat 6系列系統來安裝zabbix客戶端，而且客戶端的版本是2.0.6.
下面是playbook的結構

?

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33

14:29:30 # pwd /etc/ansible/roles root@ip-10-10-10-10: /etc/ansible/roles 14:29:37 # tree zabbix_client_* zabbix_client_delete  刪除已經安裝的zabbix客戶端 ├── files      存放文件的 ├── handlers    重啓的東東 ├── meta      galaxy_info的信息 │  └── main.yml  ├── tasks      操做的任務流程 │  ├── delete.yml │  └── main.yml ├── templates    模板 └── vars      變量    └── main.yml zabbix_client_install ├── files │  └── zabbix-2.0.6. tar .gz ├── handlers ├── meta │  └── main.yml ├── tasks │  ├── copy.yml │  ├── delete.yml │  ├── install .yml │  └── main.yml ├── templates │  ├── zabbix_agentd │  └── zabbix_agentd.conf └── vars    └── main.yml    12 directories, 13 files

下面是先介紹一下安裝方面zabbix_client_install的內容
一、galaxy_info的信息

?

1 2 3 4 5 6 7 8 9 10 11 12 13

14:32:15 # cat /etc/ansible/roles/zabbix_client_install/meta/main.yml galaxy_info:   author: Deng Lei   description: Install Zabbix Client   license: MIT   min_ansible_version: 1.6   platforms:   - name: CentOS    versions:    - 6   categories:   - Monitor dependencies: []

二、task裏的copy.xml信息

?

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30

14:33:35 # cat /etc/ansible/roles/zabbix_client_install/tasks/copy.yml   - name: Stop Exist Zabbix Client Service In Redhat Client    shell: ps -ef| grep zabbix| grep - v grep | awk '{print $2}' | xargs kill -9 >> /dev/null 2>&1    ignore_errors: yes    when: ansible_os_family == "RedHat" and ansible_lsb.major_release|int == 6   - name: Delete Exist Zabbix Client Dir In Redhat Client    shell: rm -rf {{ zabbix_dir }} /zabbix    ignore_errors: yes    when: ansible_os_family == "RedHat" and ansible_lsb.major_release|int == 6   - name: Install Base Require Software In Redhat Client    yum: name={{ item }} state=latest    with_items:     - telnet     - dmidecode     - tar   - name: Create Zabbix User In Redhat Client    user: name={{ zabbix_user }} state=present createhome=no shell= /sbin/nologin    when: ansible_os_family == "RedHat" and ansible_lsb.major_release|int == 6   - name: Copy Zabbix Client Software To Redhat Client    copy: src=zabbix-{{ zabbix_version }}. tar .gz dest= /tmp/zabbix- {{ zabbix_version }}. tar .gz owner=root group=root    when: ansible_os_family == "RedHat" and ansible_lsb.major_release|int == 6   - name: Uncompression Zabbix Client Software To Redhat Client    shell: tar zxf /tmp/zabbix- {{ zabbix_version }}. tar .gz -C {{ zabbix_dir }}/    when: ansible_os_family == "RedHat" and ansible_lsb.major_release|int == 6   - name: Copy Zabbix Start Script To Redhat Client    template: src=zabbix_agentd dest= /etc/init .d /zabbix_agentd owner=root group=root mode=0755    when: ansible_os_family == "RedHat" and ansible_lsb.major_release|int == 6   - name: Copy Zabbix Config To Redhat Client    template: src=zabbix_agentd.conf dest={{ zabbix_dir }} /zabbix/conf/zabbix_agentd .conf owner={{ zabbix_user }} group={{ zabbix_user }} mode=0644    when: ansible_os_family == "RedHat" and ansible_lsb.major_release|int == 6

此文件是複製對應的文件到客戶端

三、task的install.yml信息

?

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18

14:34:26 # cat /etc/ansible/roles/zabbix_client_install/tasks/install.yml   - name: Modify Zabbix Dir Permission In Redhat Client    file : path={{ zabbix_dir }} /zabbix owner={{ zabbix_user }} group={{ zabbix_user }} mode=0755    when: ansible_os_family == "RedHat" and ansible_lsb.major_release|int == 6   - name: Check Zabbix User Sudo Permission In Redhat Client    shell: grep "{{ zabbix_user }}" /etc/sudoers | wc -l    register: zabbix_sudoer    ignore_errors: True    when: ansible_os_family == "RedHat" and ansible_lsb.major_release|int == 6   - name: Give Sudo Permission To Zabbix User In Redhat Client    shell: echo "{{ zabbix_user }} ALL=(root) NOPASSWD:/bin/netstat, /usr/bin/omreport" >> /etc/sudoers    when: ansible_os_family == "RedHat" and ansible_lsb.major_release|int == 6 and zabbix_sudoer|int ==0   - name: Start Zabbix Service In Redhat Client    shell: /etc/init .d /zabbix_agentd start    when: ansible_os_family == "RedHat" and ansible_lsb.major_release|int == 6   - name: Add Boot Start Zabbix Service In Redhat Client    shell: chkconfig --level 345 zabbix_agentd on    when: ansible_os_family == "RedHat" and ansible_lsb.major_release|int == 6

此文件主要是安裝

四、tasks的delete.yml信息

?

1 2 3 4

14:35:08 # cat /etc/ansible/roles/zabbix_client_install/tasks/delete.yml   - name: Delete Zabbix compression Software In Redhat Client    shell: rm -rf /tmp/zabbix- {{ zabbix_version }}. tar .gz    when: ansible_os_family == "RedHat" and ansible_lsb.major_release|int == 6

此文件是安裝完成後，刪除安裝前的文件

五、tasks的mail.yml

?

1 2 3 4

14:35:37 # cat /etc/ansible/roles/zabbix_client_install/tasks/main.yml - include: copy.yml - include: install .yml - include: delete.yml

此文件是容許運行哪一個文件

六、templates的zabbix_agentd

?

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 61 62 63 64 65 66 67 68 69 70

15:15:45 # cat /etc/ansible/roles/zabbix_client_install/templates/zabbix_agentd #!/bin/bash # # chkconfig: - 85 15 # description: Zabbix client script. # processname: Zabbix . /etc/profile SERVICE= "Zabbix agent" DAEMON={{ zabbix_dir }} /zabbix/sbin/zabbix_agentd PIDFILE= /tmp/zabbix_agentd .pid CONFIG={{ zabbix_dir }} /zabbix/conf/zabbix_agentd .conf zabbix_agent_status=` ps aux| grep zabbix_agentd.conf| grep - v grep | wc -l` zabbix_agent_pid=` ps aux| grep zabbix_agentd| grep - v grep | awk 'NR==1{print $2}' ` # Source function library. . /etc/rc .d /init .d /functions # Source networking configuration. . /etc/sysconfig/network function check() { if [ $? - eq 0 ]; then    action $ "Operating is:" /bin/true else    action $ "Operating is:" /bin/false fi } case $1 in   'start' )    if [ -x ${DAEMON} ]    then     $DAEMON -c $CONFIG     # Error checking here would be good...     echo "${SERVICE} started."    else     echo "Can't find file ${DAEMON}."     echo "${SERVICE} NOT started."    fi    check   ;;      'stop' )    if [ -s ${PIDFILE} ]    then     if kill ` cat ${PIDFILE}` > /dev/null 2>&1     then      echo "${SERVICE} terminated."      rm -f ${PIDFILE}     fi    fi    check   ;;   'restart' )    /bin/bash $0 stop    sleep 5    /bin/bash $0 start   ;;      'status' )    if [ $zabbix_agent_status - ne 0 ]; then      echo "Zabbix Agentd is running ($zabbix_agent_pid)"    else      echo "Zabbix Agentd is not running!"    fi    ;;    *)    echo "Usage: $0 {start|stop|status|restart}" ;;    esac exit 0

這個文件是啓動客戶端的腳本

七、templates的zabbix_agentd.conf

?

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 61 62 63 64 65 66 67 68 69 70 71 72 73 74 75 76 77 78 79 80 81 82 83 84 85 86 87 88 89 90 91 92 93 94 95 96 97 98 99 100 101 102 103 104 105 106 107 108 109 110 111 112 113 114 115 116 117 118 119 120 121 122 123 124 125 126 127 128 129 130 131 132 133 134 135 136 137 138 139 140 141 142 143 144 145 146 147 148 149 150 151 152 153 154 155 156 157 158 159 160 161 162 163 164 165 166 167 168 169 170 171 172 173 174 175 176 177 178 179 180 181 182 183 184 185 186 187 188 189 190 191 192 193 194 195 196 197 198 199 200 201 202 203 204 205 206 207 208 209 210 211 212 213 214 215 216 217 218 219 220 221 222 223 224 225 226 227 228 229 230 231 232 233 234 235 236 237 238 239 240 241 242 243 244 245 246 247 248 249 250 251 252 253 254 255 256 257 258 259 260 261 262 263 264 265 266 267 268
