!includedir /etc/my.cnf.d服務啟動腳本，此腳本也要復制3份放到templates目錄內，命名為mysqld.j2,mysqld1.j2,mysqld2.j2：內部需要更改的有端口port，變量自動生成

esac 上述用到的變量在vars目錄內定義

ansbile 172.16.36.112 -m shell -a ‘echo ‘PATH=/usr/local/mysql/bin:$PATH‘ > /etc/profile.d/mariadb.sh;source /etc/profile.d/mariadb.sh‘
由於是使用多實例生成的數據庫，啟動可能稍有不便
在172.16.36.112主機上使用下列命令啟動，ss -tnlp 可以看到三個端口啟動成功和對應的mysqld服務
# bash /data/mysql/3306/bin/mysqld start
# bash /data/mysql/3307/bin/mysqld1 start
# bash /data/mysql/3308/bin/mysqld2 start
