最近公司新上架了50台服务器，系统包括centos7.3和centos6.8，现在需要在这50台服务器中安装zabbix客户端，由于本人比较懒，所以就想到了自动化工具ansible。
具体是实现方法如下：
1、playbook代码如下：
[root@deploy playbook-test]# cat zabbix-agent.yml
- hosts: web
remote_user: root
gather_facts: yes
vars:
IPDD: "{{ ansible_default_ipv4['address'] }}"
tasks:
- name: 开始拷贝源码包
copy:
#src: "/tmp/zabbix-2.2.23.tar.gz"
#dest: "/tmp/zabbix-2.2.23.tar.gz"
src: "{{ item.src }}"
dest: "{{ item.dest }}"
with_items:
- { src: "/tmp/zabbix-2.2.23.tar.gz", dest: "/tmp/zabbix-2.2.23.tar.gz" }
#- { src: "/tmp/zabbix-2.2.23.tar.gz", dest: "/tmp/zabbix-2.2.23.tar.gz" }
#- { src: "/PATH/to/FILE", dest: "/tmp/zabbix-2.2.23.tar.gz" }
- name: 开始解压源码包
unarchive:
src: "/tmp/zabbix-2.2.23.tar.gz"
dest: "/tmp"
copy: no
- name: 创建zabbix组
group:
name: zabbix
gid: 201
system: yes
state: present
- name: 创建zabbix用户
user:
name: zabbix
comment: Monitor User
uid: 201
group: zabbix
shell: /sbin/nologin
- name: 安装GCC-C++
yum:
name: gcc-c++
state: latest
- name: 开始安装zabbix客户端
shell: cd /tmp/zabbix-2.2.23 && ./configure --sysconfdir=/etc/zabbix/ --sbindir=/usr/local/sbin/ --enable-agent && make && make install
- name: 拷贝centos6启动脚本
copy:
src: "{{ item.src }}"
dest: "{{ item.dest }}"
mode: 0755
with_items:
- { src: "/tmp/zabbix-2.2.23/misc/init.d/fedora/core5/zabbix_agentd", dest: "/etc/init.d/zabbix_agentd" }
when: ansible_distribution == 'CentOS' and ansible_distribution_major_version == "6"
- name: 拷贝centos7启动脚本
copy:
src: "{{ item.src }}"
dest: "{{ item.dest }}"
mode: 0644
with_items:
- { src: "/tmp/zabbix_agentd.service", dest: "/lib/systemd/system/zabbix_agentd.service" }
when: ansible_distribution == 'CentOS' and ansible_distribution_major_version == "7"
- name: systemctl daemon-reload
command: systemctl daemon-reload
when: ansible_distribution == 'CentOS' and ansible_distribution_major_version == "7"
- name: 拷贝配置文件
template:
src: /tmp/zabbix_agentd.conf.j2
dest: /etc/zabbix/zabbix_agentd.conf
tags:
- change-conf
notify:
- restart zabbix-agent
handlers:
- name: restart zabbix-agent
service: name=zabbix_agentd state=restarted enabled=yes
2、准备源码包及相关配置文件
root@deploy tmp]# ll
total 15160
drwxr-xr-x 13 1039 1039 4096 Jul 30 2018 zabbix-2.2.23
-rw-r--r-- 1 root root 15504361 Jul 4 01:28 zabbix-2.2.23.tar.gz
-rw-r--r-- 1 root root 7465 Jul 6 01:48 zabbix_agentd.conf.j2
-rw-r--r-- 1 root root 412 Jul 6 01:13 zabbix_agentd.service
[root@deploy tmp]# grep -Ev "^#|^$" /etc/ansible/hosts
[web]
192.168.131.10
192.168.131.15
192.168.131.129
[root@deploy tmp]# grep -Ev "^#|^$" zabbix_agentd.conf.j2
PidFile=/tmp/zabbix_agentd.pid
LogFile=/tmp/zabbix_agentd.log
Server=192.168.131.100
ListenPort=10023
ServerActive=192.168.131.100
Hostname={{ IPDD }}
Timeout=30
[root@deploy tmp]# cat zabbix_agentd.service
[Unit]
Description=Zabbix Agent
After=syslog.target
After=network.target
[Service]
Environment="CONFFILE=/etc/zabbix/zabbix_agentd.conf"
EnvironmentFile=-/etc/sysconfig/zabbix-agent
Type=forking
Restart=on-failure
PIDFile=/tmp/zabbix_agentd.pid
KillMode=control-group
ExecStart=/usr/local/sbin/zabbix_agentd -c $CONFFILE
ExecStop=/bin/kill -SIGTERM $MAINPID
RestartSec=10s
[Install]
WantedBy=multi-user.target
3、测试ansible主机与客户端通信是否正常（ansible主机需要和客户端主机做ssh互信）
[root@deploy playbook-test]# ansible web -m ping
192.168.131.15 | SUCCESS => {
"ansible_facts": {
"discovered_interpreter_python": "/usr/bin/python"
},
"changed": false,
"ping": "pong"
}
192.168.131.10 | SUCCESS => {
"ansible_facts": {
"discovered_interpreter_python": "/usr/bin/python"
},
"changed": false,
"ping": "pong"
}
192.168.131.129 | SUCCESS => {
"ansible_facts": {
"discovered_interpreter_python": "/usr/bin/python"
},
"changed": false,
"ping": "pong"
}
4、执行剧本（批量部署）
[root@deploy playbook-test]# ansible-playbook zabbix-agent.yml
5、测试客户端机器zabbix-agent是否成功安装并启动
[root@deploy playbook-test]# ansible web -m shell -a "ps -ef |grep zabbix_agentd|grep -v grep"

结果显示在客户端机器上已经有zabbix_agentd的进程在运行。
6、如果需要变更配置内容，比如更改zabbix客户端的监听端口为10023，此时不需要将整个playbook都执行一遍可以在playbook相应的任务下加入tag，执行时使用“--tags”参数，指定要执行的playbook片段。
[root@deploy playbook-test]# grep -Ev "^#|^$" /tmp/zabbix_agentd.conf.j2
PidFile=/tmp/zabbix_agentd.pid
LogFile=/tmp/zabbix_agentd.log
Server=192.168.131.100
ListenPort=10023
ServerActive=192.168.131.100
Hostname={{ IPDD }}
Timeout=30
[root@deploy playbook-test]# ansible-playbook zabbix-agent.yml --tags change-conf

192.168.131.15 : ok=3 changed=2 unreachable=0 failed=0 skipped=0 rescued=0 ignored=0
结果显示配置文件已替换成功，并且跳过了其他步骤，只执行了拷贝配置文件的任务，配置文件改变，触发了重启zabbix agent的handler。
7、查看客户端监听的端口是否发生了变化
[root@deploy playbook-test]# ansible web -m shell -a "netstat -antlp | grep zabbix "
192.168.131.15 | CHANGED | rc=0 >>
tcp 0 0 0.0.0.0:10023 0.0.0.0:* LISTEN 26358/zabbix_agentd
192.168.131.10 | CHANGED | rc=0 >>
tcp 0 0 0.0.0.0:10023 0.0.0.0:* LISTEN 26427/zabbix_agentd
192.168.131.129 | CHANGED | rc=0 >>
tcp 0 0 0.0.0.0:10023 0.0.0.0:* LISTEN 11615/zabbix_agentd
ansible批量部署zabbix客户端到此结束，仅做记录，能力有限，存在很多不足，不喜勿喷。
后期更新通过ansible批量修改线上服务器用户密码。
