一、Ansible安装

环境准备

管理端:CentOS 7-2 192.168.18.147
被管理端1:CentOS 7-3 192.168.18.128
被管理端2:CentOS 7-4 192.168.18.148

管理端:
[root@localhost ~]# systemctl stop firewalld.service
[root@localhost ~]# setenforce 0
[root@localhost ~]# yum install epel-release -y
[root@localhost ~]# yum install ansible -y
[root@localhost ~]# ansible --version
ansible 2.9.2
[root@localhost ~]# yum install tree -y
[root@localhost ~]# tree /etc/ansible/
/etc/ansible/
├── ansible.cfg         #配置文件
├── hosts
└── roles

1 directory, 2 files
`配置主机清单`
[root@localhost ~]# vim  /etc/ansible/hosts
#在24行下插入以下内容
[webserver]
192.168.18.128
[mysql]
192.168.18.148

`生成密钥对`
[root@localhost ~]# ssh-keygen -t rsa
Generating public/private rsa key pair.
Enter file in which to save the key (/root/.ssh/id_rsa):        #直接回车
Created directory '/root/.ssh'.
Enter passphrase (empty for no passphrase):     #输入密码:abc123
Enter same passphrase again:                    #再次输入密码:abc123
Your identification has been saved in /root/.ssh/id_rsa.
Your public key has been saved in /root/.ssh/id_rsa.pub.
The key fingerprint is:

......此处省略多行
[root@localhost ~]# cd .ssh/
[root@localhost .ssh]# ls
id_rsa(私钥)  id_rsa.pub(公钥)

`把密钥推给被管理端1`
[root@localhost .ssh]# ssh-copy-id root@192.168.18.128
/usr/bin/ssh-copy-id: INFO: Source of key(s) to be installed: "/root/.ssh/id_rsa.pub"

验证密钥是否推送成功:

被管理端1:192.168.18.128
[root@localhost ~]# systemctl stop firewalld.service
[root@localhost ~]# setenforce 0
[root@localhost ~]# cd .ssh/
[root@localhost .ssh]# ls
authorized_keys
#此时密钥推送成功
被管理端2:
[root@localhost ~]# systemctl stop firewalld.service
[root@localhost ~]# setenforce 0
[root@localhost ~]# cd .ssh/
[root@localhost .ssh]# ls
authorized_keys
#此时密钥推送成功

二、Ansible命令行模块

1、command模块

`使用IP地址查看被管理端1的时间`
[root@localhost .ssh]# ansible 192.168.18.128 -m command -a 'date'
Enter passphrase for key '/root/.ssh/id_rsa':       #输入密钥密码abc123
192.168.18.128 | CHANGED | rc=0 >>
2020年 02月 02日 星期日 15:53:20 CST
`使用别名查看被管理端2的时间`
[root@localhost .ssh]# ansible mysql -m command -a 'date'
Enter passphrase for key '/root/.ssh/id_rsa':       #输入密钥密码abc123
192.168.18.148 | CHANGED | rc=0 >>
2020年 02月 02日 星期日 15:55:13 CST

`为避免总是输入密码的麻烦,我们可以执行免交互代理`
[root@localhost .ssh]# ssh-agent bash
[root@localhost .ssh]# ssh-add
Enter passphrase for /root/.ssh/id_rsa:             #输入密钥密码abc123   
Identity added: /root/.ssh/id_rsa (/root/.ssh/id_rsa)

[root@localhost .ssh]# ansible webserver -m command -a 'date'
192.168.18.128 | CHANGED | rc=0 >>
2020年 02月 02日 星期日 16:01:40 CST
#此时可以免交互直接显示时间

`所有hosts主机执行date命令`
[root@localhost .ssh]# ansible all -a 'date'
192.168.18.128 | CHANGED | rc=0 >>
2020年 02月 02日 星期日 16:21:08 CST

192.168.18.148 | CHANGED | rc=0 >>
2020年 02月 02日 星期日 16:21:08 CST

2、cron模块

两种状态(state):present表示添加(可以省略),absent表示移除

[root@localhost .ssh]# ansible mysql -m cron -a 'minute="*/1" job="/usr/bin/echo hello"  name="test hello"'
192.168.18.148 | CHANGED => {
    "ansible_facts": {
        "discovered_interpreter_python": "/usr/bin/python"
    },
    "changed": true,
    "envs": [],
    "jobs": [
        "test hello"
    ]
}
[root@localhost .ssh]# ansible mysql -a 'crontab -l'
192.168.18.148 | CHANGED | rc=0 >>
#Ansible: test hello
*/1 * * * * /usr/bin/echo hello
此时我们可以进入被管理端2进行验证:
[root@localhost .ssh]# crontab -l
#Ansible: test hello
*/1 * * * * /usr/bin/echo hello
您在 /var/spool/mail/root 中有新邮件

[root@localhost .ssh]# vim /var/spool/mail/root

hello
#以下省略多行,每分钟生成一个
此时移除计划性任务,使用absent:
[root@localhost .ssh]# ansible mysql -m cron -a 'name="test hello" state=absent'
192.168.18.148 | CHANGED => {
    "ansible_facts": {
        "discovered_interpreter_python": "/usr/bin/python"
    },
    "changed": true,
    "envs": [],
    "jobs": []
}

`此时再回到被管理端2中会发现计划任务消失`
[root@localhost ~]# crontab -l

3、user模块

user模块是请求的是useradd, userdel, usermod三个指令

`创建用户test01`
[root@localhost ~]# ansible all -m user -a 'name=test01'

}
`此时回到被管理端1中验证添加用户`
[root@localhost ~]# id test01
uid=1001(test01) gid=1001(test01) 组=1001(test01)
`此时回到被管理端2中验证添加用户`
[root@localhost ~]# id test01
uid=1001(test01) gid=1001(test01) 组=1001(test01)
#此时两台被管理端test01用户均添加成功

`删除webserver端中的test01用户`
[root@localhost ~]# ansible webserver -m user -a 'name=test01 state=absent'
192.168.18.128 | CHANGED => {
    "ansible_facts": {
