环境准备：

1、生成私钥，对另外三台主机进行免密登入

[root@ansible ~]# ssh-keygen -t rsa
Generating public/private rsa key pair.
Enter file in which to save the key (/root/.ssh/id_rsa): 
/root/.ssh/id_rsa already exists.
Overwrite (y/n)? yes
Enter passphrase (empty for no passphrase): 
Enter same passphrase again: 
Your identification has been saved in /root/.ssh/id_rsa.
Your public key has been saved in /root/.ssh/id_rsa.pub.
The key fingerprint is:
SHA256:Ny1q6A+oJY8ZDV3+eX0hpKzOYWvrtR5/FipNa7DWj+0 root@ansible
The key's randomart image is:
+---[RSA 3072]----+

[root@ansible ~]# ssh-copy-id -i /root/.ssh/id_rsa.pub 192.168.160.132
[root@ansible ~]# ssh-copy-id -i /root/.ssh/id_rsa.pub 192.168.160.137
[root@ansible ~]# ssh-copy-id -i /root/.ssh/id_rsa.pub 192.168.160.139

2.构建Ansible清单

[root@ansible ~]# cd /etc/ansible/
[root@ansible ansible]# vim hosts 
//添加受管主机
192.168.160.132
192.168.160.137
192.168.160.139

3. 受管主机安装python3

[root@nginx ~]# yum -y install python3
[root@mysql ~]# yum -y install python3
[root@php ~]# yum -y install python3

4. 管理nginx受管主机部署nginx服务

//创建系统用户nginx
[root@ansible ansible]# ansible 192.168.160.132 -m user -a 'name=nginx system=yes shell=/sbin/nologin state=present'//安装依赖包

[root@ansible ansible]# ansible 192.168.160.132 -a 'tar xf nginx-1.20.2.tar.gz'//编写编译脚本，然后进行编译安装
[root@ansible ansible]# mkdir scripts/
