实现：

第一步准备环境：

当然ansible的密钥已经向节点批量分发完毕

测试所有受管节点是否存活：

[root@m01 ~]# ansible all -m ping 
172.16.1.7 | SUCCESS => {
    "ansible_facts": {
        "discovered_interpreter_python": "/usr/bin/python"
    }, 
    "changed": false, 
    "ping": "pong"
}
172.16.1.8 | SUCCESS => {
    "ansible_facts": {
        "discovered_interpreter_python": "/usr/bin/python"
    }, 
    "changed": false, 
    "ping": "pong"
}
172.16.1.41 | SUCCESS => {
    "ansible_facts": {
        "discovered_interpreter_python": "/usr/bin/python"
    }, 
    "changed": false, 
    "ping": "pong"
}
172.16.1.31 | SUCCESS => {
    "ansible_facts": {
        "discovered_interpreter_python": "/usr/bin/python"
    }, 
    "changed": false, 
    "ping": "pong"
}

模拟环境：

ansible all -m shell -a 'mkdir -p /backup /server/scripts'
ansible web -m shell -a 'mkdir -p /upload /var/html/www /app/logs'
ansible nfs -m shell -a 'mkdir -p /data'

rsync全网备份：

2.实现web01 web02 挂载nfs到 /upload目录，实现开机自动挂载和解决nfs耦合性过高问题

3.实现nfs共享的目录与backup服务器通过rersync进行实时同步
Playbook

测试：

nice!
