1.Ansible安装以及配置

时间：2023-01-17 06:03:58

本节内容以Centos7为系统环境进行讲解：

1.安装epel源，方便直接yum安装：

 wget -O /etc/yum.repos.d/epel.repo http://mirrors.aliyun.com/repo/epel-7.repo

2.yum安装ansible:

yum -y install ansible

3.对ansible的hosts文件进行配置:

[root@sdrtest ~]# vi  /etc/ansible/hosts

[root@sdrtest ~]# cat /etc/ansible/hosts

[webservers]

139.224.239.128

4.不上上面没有进行的ssh免密登录的操作，配置免密登录后操作会更简便一点：

[root@sdrtest ~]# cd .ssh

[root@sdrtest .ssh]# ssh-keygen -t rsa

Enter file in which to save the key (/root/.ssh/id_rsa):  //回车

Enter passphrase (empty for no passphrase):  //回车

Enter same passphrase again:  //回车

[root@sdrtest .ssh]# ssh-copy-id 139.224.239.128

root@139.224.239.128's password:   //输入需要远程免密的机器的密码

5.在机器上面本地进行ansible操作以验证ssh免密登录是否已经操作成功：

[root@sdrtest .ssh]# ansible all -m shell -a 'ifconfig'

6.ansible各参数对应的意义注解：

ansible all[指定主机组] -m[指定模块] shell[shell模块] -a[指定模块使用的参数]  'ifconfig|grep 56'[模块使用的参数]
