ansible基础

1、安装

注意：需要有python环境

yum -y install ansibel

查看ansible版本：

ansible --version

ansible 2.9.25

  config file = /etc/ansible/ansible.cfg

  configured module search path = [u'/root/.ansible/plugins/modules', u'/usr/share/ansible/plugins/modules']

  ansible python module location = /usr/lib/python2.7/site-packages/ansible

  executable location = /bin/ansible

  python version = 2.7.5 (default, Apr  2 2020, 13:16:51) [GCC 4.8.5 20150623 (Red Hat 4.8.5-39)]

2、配置文件

注意在/etc/hosts中做好域名解析

vim /etc/ansible/hosts 

[webserver]    

host1     #主机名称

host2

host3

#涉及端口/密码/用户名

[webserver]    

host1     

host2

host3

#变量

[webserver:vars]

ansible_ssh_user='test'    #用户名

ansible_ssh_port='9347'   #端口

ansible_ssh_pass='******'  #密码

#主机密码/端口/用户名不同时，要分开写

[webserver]

host1 ansible_ssh_user='test' ansible_ssh_pass='******'

host[2:4] ansible_ssh_user='login' ansible_ssh_pass='******'

#将不同的变量进行组合

[apache]

host[1:2]

[nginx]

host[3:4]

[webserver:children]

apache

nginx

[webserver:vars]

ansible_ssh_user='test'

ansible_ssh_pass='******'

#普通账户提权

ansible_become=true

ansible_become_method=sudo

ansible_become_user=root

3、测试

ansible webserver -m ping -o

gitlab-server | SUCCESS => {"ansible_facts": {"discovered_interpreter_python": "/usr/bin/python"}, "changed": false, "ping": "pong"}

tengxun-server | SUCCESS => {"ansible_facts": {"discovered_interpreter_python": "/usr/bin/python"}, "changed": false, "ping": "pong"}

ftp-server | SUCCESS => {"ansible_facts": {"discovered_interpreter_python": "/usr/bin/python"}, "changed": false, "ping": "pong"}
