被管理端：192.168.80.102
yum install -y epel-release //安装epel源
yum install ansible -y
ansible --version //查看ansible版本
yum install tree -y
tree /etc/ansible/ 树状结构展示文件夹
/etc/ansible/
├── ansible.cfg #ansible的配置文件

└── roles #
cd /etc/ansible
vi hosts 添加以下内容
[webserver]
192.168.80.101
[mysql]
192.168.80.102
ssh-keygen -t rsa 直接回车就行
ssh-copy-id [email protected]
ssh-copy-id [email protected] //配置密钥对验证
---------ansible命令行模块--------
------command模块------
命令格式：ansible [主机] [-m 模块] [-a args]
ansible-doc -l //列出所有已安装的模块 注：按q退出
ansible-doc -s yum //-s列出yum模块描述信息和操作动作
ansible 192.168.80.101 -m command -a ‘date’ //指定ip执行date
ansible webserver -m command -a ‘date’ //指定分类执行date
ansible mysql -m command -a ‘date’
ansible all -m command -a ‘date’ //所有hosts主机执行date命令
ansible all -a ‘ls /’ 如果不加-m模块，则默认运行command模块 查看根目录下的文件
-----cron模块------ 计划任务模块
两种状态（state）：present表示添加（可以省略），absent表示移除。
ansible-doc -s cron //查看cron模块信息
ansible webserver -m cron -a ‘minute="*/1" job="/bin/echo heihei" name=“test cron job”’
ansible webserver -a ‘crontab -l’
ansible webserver -m cron -a ‘name=“test cron job” state=absent’ //移除计划任务，假如该计划任务没有取名字，name=None即可
-----user模块------ 用户模块
user模块是请求的是useradd, userdel, usermod三个指令
ansible-doc -s user
ansible mysql -m user -a ‘name=“test01”’ //创建用户test01
ansible mysql -m command -a ‘tail /etc/passwd’
ansible mysql -m user -a ‘name=“test01” state=absent’ //删除用户test01
-----group模块-----组模块
group模块请求的是groupadd, groupdel, groupmod 三个指令。
ansible-doc -s group
ansible mysql -m group -a ‘name=mysql gid=306 system=yes’ 创建组gid为306可以登陆到系统中的mysql用户
ansible mysql -a ‘tail /etc/group’
ansible mysql -m user -a ‘name=test01 uid=306 system=yes group=mysql’
ansible mysql -a ‘tail /etc/passwd’
ansible mysql -a ‘id test01’
------copy模块-------- 复制模块
ansible-doc -s copy
ansible mysql -m copy -a ‘src=/etc/fstab dest=/opt/fstab.back owner=root mode=640’
ansible mysql -a ‘ls -l /opt’
ansible mysql -a ‘cat /opt/fstab.back’
ansible mysql -m copy -a ‘content=“hello heihei!”
dest=/opt/fstab.back’ //将hello heihei!写入覆盖到/opt/fstab.back
ansible mysql -a ‘cat /opt/fstab.back’
------file模块--------
ansible-doc -s file
ansible mysql -m user -a ‘name=mysql system=yes’
ansible mysql -m group -a ‘name=mysql system=yes’
ansible mysql -m file -a ‘owner=mysql group=mysql mode=644 path=/opt/fstab.back’ //修改文件的属主属组权限等
设置/opt/fstab.link为/opt/fstab.back的链接文件
ansible mysql -m file -a ‘path=/opt/fstab.link src=/opt/fstab.back state=link’
ansible mysql -a ‘ls -l /opt’
ansible mysql -m file -a “path=/opt/fstab.back state=absent” //删除一个文件
ansible mysql -m file -a “path=/opt/test state=touch” 创建一个test文件
-----ping模块------- 测试网络连通性
ansible all -m ping
-----service模块--------

在webserver中启动httpd服务
systemctl start httpd
ansible webserver -a ‘systemctl status httpd’
ansible webserver -m service -a ‘enabled=true name=httpd state=started’ //启动httpd服务 
systemctl status httpd //查看是否开启
