2、编写脚本，获取mysql的各种状态值。可以固定一个目录，专门存放监控脚本。比如/usr/local/zabbix/scripts/chk_mysql.sh

#!/bin/bash

MYSQL_CONN="/alidata/mysql/bin/mysqladmin -u ${MYSQL_USER} -p${MYSQL_PWD} -h${MYSQL_HOST} -P${MYSQL_PORT}"

# 参数是否正确
if [ $# -ne "1" ];then 
 echo "arg error!" 
fi 

# 获取数据
case $1 in 
 Uptime) 
 result=`${MYSQL_CONN} status|cut -f2 -d":"|cut -f1 -d"T"` 
 echo $result 
 ;; 
 Com_update) 
 result=`${MYSQL_CONN} extended-status |grep -w "Com_update"|cut -d"|" -f3` 
 echo $result 
 ;;

 echo $result 
 ;;

 echo $result 
 ;;

 echo $result

 echo $result

 echo "Usage:___FCKpd___0(Uptime|Com_update|Slow_queries|Com_select|Com_rollback|Questions|Com_insert|Com_delete|Com_commit|Bytes_sent|Bytes_received|Com_begin)" 
 ;; 
esac

3、修改zabbix的配置文件/usr/local/zabbix-agentd/etc/zabbix_agentd.conf，添加

#获取mysql版本
UserParameter=mysql.version,mysql -V
##获取mysql性能指标,这个是上面定义好的脚本
UserParameter=mysql.status[*],bash /alidata/zabbix-agentd/scripts/chk_mysql.sh $1
##获取mysql运行状态
UserParameter=mysql.ping,/alidata/mysql/bin/mysqladmin -uroot -pliujinWANG1985 -P3306 -h127.0.0.1 ping | grep -c alive
UserParameter=mysql.process,/alidata/mysql/bin/mysql -uroot -pliujinWANG1985 -P3306 -h127.0.0.1 -e "show processlist" 2>/dev/null|wc -l

4、重启zabbix的客户端
