Ansible添加主机清单

1、基于端口，用户，密码定义主机清单

格式：
ansible基于ssh连接-i（inventory）参数后指定的远程主机时，也可以写端口，用户，密码。
如：
ansible_ssh_port: 指定ssh端口 
ansible_ssh_user: 指定 ssh 用户 
ansible_ssh_pass: 指定 ssh 用户登录是认证密码（明文密码不安全）
ansible_sudo_pass: 指明 sudo 时候的密码

注意：使用密码时，需要把ssh的验证秘钥关闭

echo "StrictHostKeyChecking no" >> $HOME/.ssh/config

ansible默认的主机清单文件在 /etc/ansible/hosts

1) 添加的内容如下

vim /etc/ansible/hosts
[test_qy]			# 组
172.31.0.12 ansible_ssh_port=22 ansible_ssh_user=root ansible_ssh_pass="Wstest#2022"

2) 测试连通

[root@4h6wu6327422sz ansible]# ansible -i /etc/ansible/hosts test_qy -m  ping 
172.31.0.12 | SUCCESS => {
    "ansible_facts": {
        "discovered_interpreter_python": "/usr/bin/python"
    }, 
    "changed": false, 
    "ping": "pong"
}

-i 指定主机清单的位置
test_qy hosts文件中组中的所有主机
-m ping -m 指定模块

2、基于ssh密钥来访问定义主机清单

1）设置密钥：

ssh-keygen		# 一直回车

2）拷贝密钥：

[root@4h6wu6327422sz ansible]# ssh-copy-id 172.31.0.15
/bin/ssh-copy-id: INFO: Source of key(s) to be installed: "/root/.ssh/id_rsa.pub"
/bin/ssh-copy-id: INFO: attempting to log in with the new key(s), to filter out any that are already installed
/bin/ssh-copy-id: INFO: 1 key(s) remain to be installed -- if you are prompted now it is to install the new keys
[email protected]'s password: 		输入密码

Number of key(s) added: 1

Now try logging into the machine, with:   "ssh '172.31.0.15'"
and check to make sure that only the key(s) you wanted were added.

3) 添加172.31.0.15主机到 /etc/ansible/hosts 的test-qy组下

[test_qy]
172.31.0.12 ansible_ssh_port=22 ansible_ssh_user=root ansible_ssh_pass="Wstest#2022"
172.31.0.15

4) 查看test_qy组下所有主机

[root@4h6wu6327422sz ansible]# ansible test_qy --list
hosts (2):
    172.31.0.12
    172.31.0.15

5）测试172.31.0.15主机的连通

[root@4h6wu6327422sz ansible]# ansible -i /etc/ansible/hosts 172.31.0.15 -m ping 
172.31.0.15 | SUCCESS => {
    "ansible_facts": {
        "discovered_interpreter_python": "/usr/bin/python"
    }, 
    "changed": false, 
    "ping": "pong"
}
