ansible+playbook 搭建lnmp环境

用三台机器做ansible+playbook 搭建lnmp环境

IP分配

ansible 主机192.168.202.132

lnmp第一台主机 192.168.202.131

lnmp第一台主机 192.168.202.133

1.1 ansible主机安装ansible

[root@localhost ~]# yum -y install ansible
已加载插件：fastestmirror
Loading mirror speeds from cached hostfile
 * base: mirror.jdcloud.com
 * extras: mirror.bit.edu.cn

1.2 ansible主机生成密钥设置免密码登录

[root@localhost ~]# ssh -keygen
Bad escape character 'ygen'.
[root@localhost ~]# ssh-keygen
Generating public/private rsa key pair.
Enter file in which to save the key (/root/.ssh/id_r
Created directory '/root/.ssh'.
Enter passphrase (empty for no passphrase): 
Enter same passphrase again: 
Your identification has been saved in /root/.ssh/id_
Your public key has been saved in /root/.ssh/id_rsa.
The key fingerprint is:
SHA256:snafmBirD5A4bkRNfs/yraWQ7BqJf4SKpLd0UO5yZyA rhost
The key's randomart image is:
+---[RSA 2048]----+

and check to make sure that only the key(s) you wantdded.
[root@localhost ~]# ssh-copy-id root@192.168.202.133

1.3 ansible主机配置

[root@localhost ~]# vim /etc/ansible/hosts 

[lnmp]
192.168.202.131
192.168.202.133

　如图：

1.4 编写ansible的playbook
