Ansible-playbook install Zabbix_agent
一、创建目录
在下面显示的目录结构中，包含了zabbix安装、卸载和配置三个角色(roles)，以及每一个roles的所有tasks列表、vars变量和zabbix配置文件。其中安装和卸载分别通过zabbix_install.yml、zabbix_delete.yml主任务程序的入口文件调用
规划如下：

[root@ansible

[root@ansible
/etc/ansible/zabbix_rhel/zabbix_agent

# vim roles/install/tasks/02-copy-code.yml

- name: Copy zabbix agentd code

to clients
copy: src=ansible-zabbix-{{ zabbix_version }}.

/sbin/zabbix_agentd
/usr/local/sbin/zabbix_agentd
- name: Delete ansible-zabbix-{{ zabbix_version }}.
tar
.gz
source
file
shell:
rm
-rf
/usr/local/src/ansible-zabbix-
{{ zabbix_version }}.
tar
.gz
|
4、定义安装程序-启动zabbix_agentd服务任务03-start-zabbix.yml
|

|
[root@ansible
/etc/ansible/zabbix_rhel/zabbix_agent
]
# vim roles/install/tasks/03-start-zabbix.yml
---
- name: Start zabbix service
shell:
/etc/init
.d
/zabbix_agentd
start
- name: Add boot start zabbix service
shell: chkconfig --level 345 zabbix_agentd on
|
5、定义安装程序-添加iptable规则04-add-iptables.yml
|

7
|
[root@ansible
/etc/ansible/zabbix_rhel/zabbix_agent
]
# vim roles/install/tasks/04-add-iptables.yml
---
- name: insert iptables rule
for
zabbix
lineinfile: dest=
/etc/sysconfig/iptables
create=
yes
state=present regexp=
"{{ zabbix_agentd_port }}"
insertafter=
"^:OUTPUT "
line=
"-A INPUT -p tcp --dport {{ zabbix_agentd_port }} -s {{ zabbix_server_ip }} -j ACCEPT"
notify: restart iptables
|
6、定义安装程序-tasks任务列表的主调用接口文件main.yml
|
1
2

|
[root@ansible
/etc/ansible/zabbix_rhel/zabbix_agent
]
# vim roles/install/tasks/main.yml
---
- include: 01-create-user.yml
- include: 02-copy-code.yml
- include: 03-start-zabbix.yml
- include: 04-add-iptables.yml
|
tasks任务列表说明：
Playbook允许用户将tasks任务细分为多个任务列表，通过一个main任务来调用。当然你也可以将涉及的所有任务全部写到main.yml文件中。
7、定义common任务
该任务为安装一些依赖软件包
|

|
[root@ansible
/etc/ansible/zabbix_rhel/zabbix_agent
]
# vim roles/common/tasks/main.yml
- name: Install initializtion require software
yum: name={{ item }} state=latest
with_items:
- libselinux-python
- libcurl-devel
|
三、安装程序的vars变量文件
在roles/install/vars/目录中创建main.yml文件，并定义安装过程中使用到变量
|
1
2
3
4
5
6
7
|
[root@ansible
/etc/ansible/zabbix_rhel/zabbix_agent
]
# vim roles/install/vars/main.yml
zabbix_dir:
/usr/local/zabbix
zabbix_version: 3.0.8
zabbix_user: zabbix
zabbix_server_port: 10051
zabbix_agentd_port: 10050
zabbix_server_ip: 10.17.81.120
|
四、安装程序的handlers任务定义
handlers目录中为tasks任务中notify调用的动作（当文件发生改变时，通过notify执行相关的操作，比如修改了配置文件后，需要重启相应的服务）
|
1
2
3
4
|
[root@ansible
/etc/ansible/zabbix_rhel/zabbix_agent
]
# vim roles/install/handlers/main.yml
---
- name: restart iptables
service: name=iptables state=restarted
|
五、安装程序的zabbix安装文件
将预先编译好的zabbix打包后，放到files/目录中，Playbook在执行操作过程中会根据tasks任务将文件发送到目标主机上
|
1
2
|
[root@ansible
/etc/ansible/zabbix_rhel/zabbix_agent
]
# ls roles/install/files/
ansible-zabbix-3.0.8.
tar
.gz
|
六、安装程序的zabbix配置文件
使用Playbook安装zabbix涉及的所有配置文件都通过templates模块去同步
|
1
2
|
[root@ansible
/etc/ansible/zabbix_rhel/zabbix_agent
]
# ls roles/install/templates/
zabbix_agentd zabbix_agentd.conf
|
在安装任务中，zabbix_agentd.conf配置文件主要涉及zabbix服务端IP地址的修改，可以通过预定义的变量来替换
zabbix_agentd.conf文件如下
