主要完成通过playbook自动生成zabbix_server,agent，这里没有完全实现自动化，这里机器的获取还是需要人为手工填写，如果感兴趣想通过自动获取需要部署的机器可以通过namp扫描工具awk命令截取，这里不过多描述。我用两台机器做的测试，老版本的模块用法会有差异，如果无法执行可以通过官网去查看https://ansible-tran.readthedocs.io/en/latest/,参考文档https://www.cnblogs.com/LyShark/p/10886486.html
ansible 2.4.2
zabbix 3.4.15
安装nmap扫描工具
yum install nmap -y
#通过ping探测172.16.9.0网段中存活机器
nmap -sP 172.16.9.0/24完成机器间的免密登录
生成公钥对
ssh-keygen -t rsa设置ansible hosts配置
[test]
172.16.9.141 ansible_ssh_user="root" ansible_ssh_pass="root"
172.16.9.142 ansible_ssh_user="root" ansible_ssh_pass="root"
[zabbix_server]
172.16.9.141
[zabbix_client]
172.16.9.142批量推送公钥到集群节点
- hosts: test
user: root
tasks:
- name: ssh-copy
authorized_key: user=root key="{{ lookup('file', '/root/.ssh/id_rsa.pub') }}"
tags:
- sshkey报错:
FAILED! => {"msg": "Using a SSH password instead of a key is not possible because Host Key checking is enabled and sshpass does not support this. Please add this host's fingerprint to your known_hosts file to manage this host."}解决：
/etc/ansible/ansible.cfg
修改host_key_checking(默认是check的)
playbook构建zabbix_server(官方建议一个play写一个独立的任务，测试不过多计较了)
