1、在group1的被管理机里的mariadb里创建一个abc库；

1）

然后我们到agent主机上进行检查：

可以看到数据库已经创建成功。

再看几个其他命令：

#a组主机重启mysql，并设置开机自启
ansible a -m service -a "name=mysql enabled=yes state=restarted"

script模块：

script模块用于在远程主机上执行本地脚本。

脚本在master上，但是可以在agent服务器上执行。

[root@localhost ~]# cat /tmp/1.sh
#!/bin/bashyum install -y mariadb-server &> /dev/nullsystemctl start mariadb
systemctl enable mariadbmysql << EOF
create database abc;
quit
EOF

说明：上面这个创建数据库的方法可以参考下。

[root@localhost ~]# ansible group1 -m script -a "/tmp/1.sh"
