安装

yum install epel-release -y
yum install ansible –y

ansible 程序结构
      安装目录如下(yum安装)：
　　配置文件目录：/etc/ansible/
　　执行文件目录：/usr/bin/
　　Lib库依赖目录：/usr/lib/pythonX.X/site-packages/ansible/
　　Help文档目录：/usr/share/doc/ansible-X.X.X/
　　Man文档目录：/usr/share/man/man1/  

编辑主机配置文件

vim /etc/ansible/hosts   

[Client]

    192.168.64.135
    192.168.64.140
    192.168.64.136
    192.168.64.137

命令查看主机列表

ansible Client --list

 

ansible 配置公私钥

ssh-keygen 回车 连续按3下 密钥就形成了

分发密钥(保证可以通信情况下 进行密钥分发)

ssh-copy-id root@192.168.64.135 

ssh-copy-id root@192.168.64.1356

ssh-copy-id root@192.168.64.137 等

分发完成

 

测试一下

ansible Client -m ping

192.168.64.140 | SUCCESS => {
    "ansible_facts": {
        "discovered_interpreter_python": "/usr/bin/python"
    }, 
    "changed": false, 
    "ping": "pong"
}
192.168.64.136 | SUCCESS => {
    "ansible_facts": {
        "discovered_interpreter_python": "/usr/bin/python"
    }, 
    "changed": false, 
    "ping": "pong"
}
192.168.64.135 | SUCCESS => {
    "ansible_facts": {
        "discovered_interpreter_python": "/usr/bin/python"
    }, 
    "changed": false, 
    "ping": "pong"
}
192.168.64.137 | UNREACHABLE! => {
    "changed": false, 
    "msg": "Failed to connect to the host via ssh: ssh: connect to host 192.168.64.137 port 22: No route to host", 
    "unreachable": true
}

大功告成了
