一、下载ansible软件包
ps：需要依赖epel源，提前设置好
[root@ m01 ~]# yum install -y ansible
Loaded plugins: fastestmirror

* extras: mirrors.aliyun.com
* updates: mirrors.aliyun.com
base | 3.6 kB 00:00
epel | 4.7 kB 00:00

Package ansible-2.9.18-1.el7.noarch already installed and latest version
本机已经提前安装好。
[root@ m01 ~]# cat /etc/ansible/ansible.cfg
ansible服务配置文件
主机清单文件，定义可以管理的主机
[root@ m01 ~]# cat /etc/ansible/hosts
# This is the default ansible 'hosts' file.
#
# It should live in /etc/ansible/hosts
#
# - Comments begin with the '#' character
# - Blank lines are ignored
# - Groups of hosts are delimited by [header] elements
# - You can enter hostnames or ip addresses
# - A hostname/ip can be a member of multiple groups
# Ex 1: Ungrouped hosts, specify before any group headers.
## green.example.com
## blue.example.com
## 192.168.100.1
## 192.168.100.10
# Ex 2: A collection of hosts belonging to the 'webservers' group
## [webservers]
## alpha.example.org
## beta.example.org
## 192.168.1.100
## 192.168.1.110
# If you have multiple hosts following a pattern you can specify
# them like this:
## www[001:006].example.com
# Ex 3: A collection of database servers in the 'dbservers' group
## [dbservers]
##
## db01.intranet.mydomain.net
## db02.intranet.mydomain.net
## 10.25.1.56
## 10.25.1.57
# Here's another example of host ranges, this time there are no
# leading 0s:
## db-[99:101]-node.example.com
#定义可以管理主机的信息
172.168.3.31
172.168.3.41
172.168.3.7
=========================================
/etc/ansible/roles
角色目录
二、编写主机清单文件
[root@ m01 ~]# echo "#定义可以管理的主机信息/n172.168.3.41/n172.168.3.31/n172.168.7" >> /etc/ansible/hosts
三、测试是否可以管理多个主机
[root@ m01 ~]# ansible all -a "hostname"
172.168.3.41 | CHANGED | rc=0 >>
backup
172.168.3.31 | CHANGED | rc=0 >>
