安装ansible需要epel源，所以第一步就是下载epel源，当然环境清理也是少不了的,做好前面的工作之后就可以安装ansible啦，

第一步：安装epel源

# yum install -y epel-release

# yum makecache

第二步：清理环境

# systemctl status iptalbes

# systemctl stop iptables

# systemctl disable iptables

# systemctl status firewalld

# systemctl stop firewalld

# systemctl disable firewalld

# systemctl status NetworkManager

# systemctl stop NetworkManager

# systemctl disable NetworkManager

# getenforce

# vim /etc/selinux/config

    selinux=enforcing改成selinux=disabled

第三步：安装ansible

# yum install -y ansible

# ansible --version

#  vim /etc/ansible/hosts添加你要控制的主机(本机的IP 192.168.87.26  控制的主机IP 192.168.87.25 控制主机的密码是'nn123')

[client]

192.168.87.25 ansible_ssh_user=root ansible_ssh_pass='nn123'

# ssh-keygen -t rsa

# ssh-agent bsh

# ssh-copy-id -i root@192.168.87.25(一路回车有输入密码的提示就输入密码即可)

# ansible -m ping 192.168.87.25显示如下则是正确的

然后ansible就安装完成啦。
