1. Configuration of ansible host inventory

The following is the source file after the ansible installation is complete

[root@test-1] # 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 [webservers] 192.168.200.131 ansible_host_user=root ansible_host_pass='123456' 192.168.200.132 192.168.200.133 192.168.200.134 192.168.200.135 192.168.200.136 # # 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 [001VAN006] .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 db- 101]-node.example.com

2. How ansible is defined:

1) specify the host address or host name directly

Test_2.xxxx.cn2 192.168.200.132

2) define a host group [group name] add the address or host name

[webservers] 192.168.200.131 ansible_host_user=root ansible_host_pass='123456' 192.168.200.132 192.168.200.133 192.168.200.134 192.168.200.135 192.168.200.136

3) if you do not use the public key and want to use the password, you can also write this (for first login control)

Format: [hostname] [specified user] [host address] [host password] [webservers] 192.168.200.131 ansible_host_user=root test-1=192.168.200.131 ansible_host_pass='123456'
