拷贝安装好的配置文件放入该目录，然后修改如下

之前设置的虚拟ip 172.25.11.100
通过job cache获取是成功推送

mysql salt < test.sql
yum install MySQL-python -y
salt server4 cmd.run hostname --return mysql
mysql
use salt;
show tables;
select * from salt_returns;
server4 ############可以采用下面的方法省略该步骤
vim /etc/saltstack/minion
return: mysql
mysql.host: '172.25.11.1'
mysql.user: 'salt'
mysql.pass: 'salt'
mysql.db: 'salt'
mysql.port: 3306
systemctl restart salt-minion
server1 ####用来替换server4的步骤
vim /etc/salt/master
mysql.host: 'localhost'
mysql.user: 'salt'
mysql.pass: 'salt'
mysql.db: 'salt'
mysql.port: 3306
master_job_cache: mysql
systemctl restart salt-master 这样就不用minion端修改了，可以删掉
salt server3 cmd.run df
mysql -usalt -psalt salt
select * from salt_returns;
mkdir /srv/salt/_modules
vim my_disk.py
def df(bar):
cmd = 'df -h'
return __salt__['cmd.run'](cmd)
[root@server1 _modules]# salt server4 saltutil.sync_modules
