ansible-主机清单的配置

1. ansible主机清单的配置

以下是ansible安装完成后的源文件

 1 [root@test-1 ~]# cat /etc/ansible/hosts
 2     # This is the default ansible 'hosts' file.
 3     #
 4     # It should live in /etc/ansible/hosts
 5     #
 6     #   - Comments begin with the '#' character
 7     #   - Blank lines are ignored
 8     #   - Groups of hosts are delimited by [header] elements
 9     #   - You can enter hostnames or ip addresses
10     #   - A hostname/ip can be a member of multiple groups
11
12     # Ex 1: Ungrouped hosts, specify before any group headers.
13     [webservers]
14     192.168.200.131  ansible_ssh_user=root ansible_ssh_pass='123456'
15     192.168.200.132
16     192.168.200.133
17     192.168.200.134
18     192.168.200.135
19     192.168.200.136
20
21     ## green.example.com
22     ## blue.example.com
23     ## 192.168.100.1
24     ## 192.168.100.10
25
26     # Ex 2: A collection of hosts belonging to the 'webservers' group
27
28     ## [webservers]
29     ## alpha.example.org
30     ## beta.example.org
31     ## 192.168.1.100
32     ## 192.168.1.110
33
34     # If you have multiple hosts following a pattern you can specify
35     # them like this:
36
37     ## www[001:006].example.com
38
39     # Ex 3: A collection of database servers in the 'dbservers' group
40
41     ## [dbservers]
42     ##
43     ## db01.intranet.mydomain.net
44     ## db02.intranet.mydomain.net
45     ## 10.25.1.56
46     ## 10.25.1.57
47
48     # Here's another example of host ranges, this time there are no
49     # leading 0s:
50
51     ## db-[99:101]-node.example.com

2. ansible定义方式：

　1) 直接指明主机地址或主机名

1         test_2.xxxx.cn
2         192.168.200.132

2) 定义一个主机组 [  组名  ]  把地址或主机名加进去

1         [webservers]
2         192.168.200.131  ansible_ssh_user=root ansible_ssh_pass=123456
3         192.168.200.132
4         192.168.200.133
5         192.168.200.134
6         192.168.200.135
7         192.168.200.136

3) 如果你没有使用公钥，想要使用密码，你也可以这样写（适用于第一次登陆控制）

1         格式：　　　　【主机名】       【指定用户】    　　　　　　　　　　【主机地址】   　　　　　　【主机密码】
2         [webservers]
3                 192.168.200.131    ansible_ssh_user=root    test-1=192.168.200.131      ansible_ssh_pass=123456
