playbook实战优化

环境准备

先决条件

1.首先在根目录下创建一个ansible_project 目录
[Tue Aug 17 04:17:56 root@m01 /]
 # mkdir /ansible_project
 
 2.进入到该目录下
[Tue Aug 17 04:17:56 root@m01 /]
 # cd /ansible_project/

 3.再该目录下分别创建需要准备的各项目的目录
[Tue Aug 17 04:19:25 root@m01 /ansible_project]
 # mkdir sersync
   mkdir mariadb
   mkdir nfs
   mkdir nginx
   mkdir php
   mkdir rsync
   
   4.因为是先安装rsync 所以我们先配置rsync项目，进入到rsync目录中
   [Tue Aug 17 04:38:50 root@m01 /ansible_project/rsync]
 # cp /root/ansible/rsyncd.conf   /ansible_project/rsync
 
[Tue Aug 17 05:31:21 root@m01 /ansible_project]
 # vim rsync/install_rsync.yml

    state: present
  when: ansible_hostname == 'backup' or ansible_ho
stname == 'nfs'

[Tue Aug 17 05:23:28 root@m01 /ansible_project]
 # mkdir group_vars
    mkdir host_vars
   
[Tue Aug 17 05:23:58 root@m01 /ansible_project]
