ansible自动部署 zabbix-agent 模块 的准备阶段
ansible所在的服务端可以免密钥登录所被部署的机器称为客户端。
免密钥的做法
服务端 ssh-keygen 一路回车生成密钥对
ssh-copy-id 指定IP 将公钥发给指定的ip 即可
ssh-copy-id 192.168.1.18
下面红色是代表文件或目录 黑色字体代表是内容
使用了 roles 方法 整体的目录结构是
/etc/ansible/zabbix-agent.yml
[root@localhost ansible]# pwd
/etc/ansible
/etc/ansibl/hosts
[root@localhost ansible]# cat hosts
192.168.1.145 #centso 系统
192.168.1.147 # centos 系统 加入 ansible 的客户端ip 本次示例中是这几个 ip
192.168.1.148 #ubuntu 系统
[root@localhost ansible]# cat zabbix-agent.yml
---
- hosts: all
roles:
- zabbix-agent
/etc/ansible/roles
[root@localhost ansible]# ls
zabbix-agent
/etc/ansible/zabbix-agent
[root@localhost zabbix-agent]# ls
files handlers tasks templates
/etc/ansible/zabbix-agent/files
[root@fzt146 zabbix-agent]# ls files/
zabbix
/etc/ansible/zabbix-agent/handlers
[root@fzt146 zabbix-agent]# ls handlers/
main.yml
/etc/ansible/zabbix-agent/tasks
[root@fzt146 zabbix-agent]# ls tasks/
files.yml main.yml package.yml service.yml
/etc/ansible/zabbix-agnet/templates
[root@fzt146 zabbix-agent]# ls templates/
zabbix_agentd.conf
/etc/ansible/zabbix-agent/files/zabbix/conf.d
[root@fzt146 zabbix-agent]# ls files/zabbix/conf.d/ #zabbix-agent的配置文件 键值
impression.conf imsecret.conf mystar.conf resonance.conf tagme.conf userReg.conf
/etc/ansible/zabbix-agent/files/zabbix/scripts 要复制去客户端的文件
[root@fzt146 zabbix-agent]# ls files/zabbix/scripts/ 下边是zabbix 可执行的脚本用来监控
/etc/ansible/zabbix-agent/handlers/main.yml 这个是开启zabbix-agent的
[root@fzt146 zabbix-agent]# cat handlers/main.yml
---
- name: start zabbix_agentd
service: name=zabbix-agentd state=started
/etc/ansible/zabbix-agent/tasks/files.yml 将 /etc/ansible/zabbix-agent/files/* 复制到客户端的配置
[root@fzt146 zabbix-agent]# cat tasks/files.yml
---
- name: copy centos template conf file
template: src=zabbix_agentd.conf dest=/etc/
when: ansible_os_family == "RedHat" #判断系统
- name: copy ubuntu template conf file
template: src=zabbix_agentd.conf dest=/etc/zabbix/
when: ansible_os_family == "Debian"
- name: crete conf.d and scripts
file: path={{ item }} state=directory owner=root group=root mode=0755
with_items:
- /etc/zabbix/scripts
- /etc/zabbix/conf.d
- /etc/zabbix/scripts1
- name: copy the scripts/file
copy: src=zabbix/scripts/ dest=/etc/zabbix/scripts/ mode=0755
- name: copy the scripts1/file
copy: src=zabbix/scripts1/ dest=/etc/zabbix/scripts1/ mode=0755
- name: copy the conf.d/file
copy: src=zabbix/conf.d/ dest=/etc/zabbix/conf.d/
/etc/ansible/zabbix-agent/tasks/main.yml 主的配置 在同级目录下会先执行这个main
[root@localhost zabbix-agent]# cat tasks/main.yml
---
- include: 'package.yml'
- include: 'files.yml'
- include: 'service.yml'
/etc/ansible/zabbix-agent/tasks/package.yml 安装zabbix-agent的配置
[root@localhost zabbix-agent]# cat tasks/package.yml
---
- name: useraddd the zabbix
user: name=zabbix
- name: install epel-release
yum: name=epel-release.noarch state=latest
when: ansible_os_family == "RedHat"
- name: install epel-release and zabbix_agent_package
yum: name={{ item }} state=present
with_items:
- zabbix22-agent-2.2.18-1.el6.x86_64
- zabbix22-2.2.18-1.el6.x86_64
when: ansible_os_family == "RedHat"
- name: apt-get install to ubuntu
apt: name={{ item }} state=present
with_items:
- zabbix-agent
when: ansible_os_family == "Debian"
/etc/ansible/zabbix-agent/tasks/service.yml 开启脚本 万无一失 2重开启
[root@localhost zabbix-agent]# cat tasks/service.yml
---
- name: start zabbix-agentd
service: name=zabbix-agentd state=started
when: ansible_os_family == "RedHat"
- name: start ubuntu zabbix-agent
service: name=zabbix-agent state=started
when: ansible_os_family == "Debian"
/etc/ansible/zabbix-agent/templates/zabbix_agentd.conf 配置文件的模板放在这里
[root@localhost zabbix-agent]# cat templates/zabbix_agentd.conf
PidFile=/var/run/zabbix/zabbix_agentd.pid
LogFile=/var/log/zabbix/zabbix_agentd.log
LogFileSize=100
Server=192.168.1.100 #zabbix 服务端所在的 ip
ServerActive=192.168.1.100 # zabbix-agent 主动模式 配置
Hostname={{ ansible_hostname }} #这个是系统变量
Include=/etc/zabbix/conf.d/
UnsafeUserParameters=1
# UserParameter 自定义的 监控项
具体执行
[root@localhost ansible]# pwd
/etc/ansible
[root@localhost ansible]# ansible-playbook zabbix-agent.yml
[root@localhost ansible]# ansible-playbook zabbix-agent.yml -vvvv
加 -vvv 可以看到更详细的过程 其实是 没必要的
