精简原因：
1、root账号权限太大，新建一个query账号，相关赋权：
GRANT REPLICATION CLIENT on *.* to ‘query‘@‘%‘ ;
FLUSH PRIVILEGES
2、因我的db启用了GTID，不适用于set global sql_slave_skip_counter=1命令，故取消该步骤
3、‘_Running’过滤时会剩下Slave_SQL_Running_State，不想要，改为‘_Running’

简化后脚本：
#!/bin/bash
mysql_cmd="mysql -uquery -pxxxxxxxxx"
while true
do
array=($($mysql_cmd -e "show slave status\G"|egrep ‘_Running:|Behind_Master|Last_SQL_Errno‘|awk ‘{ print $NF }‘))
if [ "${array[0]}"=="Yes" -a "${array[1]}"=="Yes" -a "${array[2]}"=="0" ]
then
echo "MySQL is slave is ok"
else
char="MySQL slave is error"
echo "$char"
echo "$char"|mail -s "$char" [email protected]
break
fi
sleep 30
done
