集群运维自动化工具ansible之使用playbook安装zabbix客户端

之前介绍了关于ansible的安装与使用（包括模块与playbook使用，地址是http://www.zzvips.com/article/99548.html），今天介绍一下如何使用playbook来部署zabbix客户端。
ansible服务端的环境为centos 6.5 x86_64系统
ansible客户端环境为centos 6.3 x86_64系统
目前我的playbook只允许centos或redhat 6系列系统来安装zabbix客户端，并且客户端的版本是2.0.6.
下面是playbook的结构

下面是先介绍一下安装方面zabbix_client_install的内容
1、galaxy_info的信息

14:32:15 # cat /etc/ansible/roles/zabbix_client_install/meta/main.yml

galaxy_info:

2、task里的copy.xml信息

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

shell: rm -rf /tmp/zabbix-{{ zabbix_version }}.tar.gz

when: ansible_os_family == "RedHat" and ansible_lsb.major_release|int == 6

此文件是安装完成后，删除安装前的文件

5、tasks的mail.yml

14:35:37 # cat /etc/ansible/roles/zabbix_client_install/tasks/main.yml

此文件是允许运行哪个文件

6、templates的zabbix_agentd

15:15:45 # cat /etc/ansible/roles/zabbix_client_install/templates/zabbix_agentd

#!/bin/bash

#

# chkconfig: - 85 15

# description: Zabbix client script.

. /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/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

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

这个文件是启动客户端的脚本
