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https://www.jb51.net/article/52154.htm），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

12 directories, 13 files

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:
 author: Deng Lei
 description: Install Zabbix Client 
 license: MIT
 min_ansible_version: 1.6
 platforms:
 - name: CentOS
  versions:
  - 6
 categories:
 - Monitor
dependencies: []

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
  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

此文件是复制对应的文件到客户端

3、task的install.yml信息

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

此文件主要是安装

4、tasks的delete.yml信息

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 
- include: copy.yml
- include: install.yml
- include: delete.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.
# 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 [ $"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

这个文件是启动客户端的脚本

此文件是客户端的配置文件
8、vars的main.yml

15:17:06 # cat /etc/ansible/roles/zabbix_client_install/vars/main.yml 
zabbix_dir: /usr/local      客户端安全目录
zabbix_version: 2.0.6      客户端软件版本
zabbix_user: zabbix       客户端用户
zabbix_port: 10050        客户端的端口
zabbix_server_ip: 192.168.1.10  zabbix_server的ip

此文件是配置变量的

9、ansible安装zabbix客户端的playbook配置文件zabbix_client_install.yml

15:20:02 # cat /etc/ansible/zabbix_client_install.yml 
---
- hosts: "{{host}}"
 remote_user: "{{user}}"
 gather_facts: True
 roles:
  - zabbix_client_install

10、使用playbook安装zabbix客户端

我的测试客户端环境是centos 6.3，ip是192.168.240.17，使用key登陆

15:22:01 # cd /etc/ansible/
root@ip-10-10-10-10:/etc/ansible
15:22:04 # time ansible-playbook zabbix_client_install.yml --extra-vars "host=192.168.240.17 user=root" --private-key=/root/test.pem

可以看到39秒就安装完成，主要花费时间比较长的地方是fact收集、yum安装、文件传输。

可以看到安装后的客户端，完全是按照我的要求来做的。

12、删除已经安装的客户端

P70系列延期，华为新旗舰将在下月发布

3月20日消息，近期博主@数码闲聊站 透露，原定三月份发布的华为新旗舰P70系列延期发布，预计4月份上市。

而博主@定焦数码 爆料，华为的P70系列在定位上已经超过了Mate60，成为了重要的旗舰系列之一。它肩负着重返影像领域顶尖的使命。那么这次P70会带来哪些令人惊艳的创新呢？

根据目前爆料的消息来看，华为P70系列将推出三个版本，其中P70和P70 Pro采用了三角形的摄像头模组设计，而P70 Art则采用了与上一代P60 Art相似的不规则形状设计。这样的外观是否好看见仁见智，但辨识度绝对拉满。
