步骤参考：zabbix使用自带模板监控MySQL - 木与风 - 博客园

先放出完整步骤：

1，创建数据库监控用户
mysql -uroot -proot
GRANT USAGE ON *.* TO 'mysqlcheck'@'localhost' IDENTIFIED BY 'mysqlcheck';
FLUSH PRIVILEGES;
注意：当出现错误：ERROR 1819 (HY000): Your password does not satisfy the current policy requirements
		说明密码复杂度较低，可以调整mysql策略
		1.1 SHOW VARIABLES LIKE 'validate_password%'; 
		1.2 set global validate_password_policy=LOW; 
		1.3 重新执行新建用户
		1.4 set global validate_password_policy=MEDIUM;
2，创建mysql，mysqladmin超链接
ln -fs /opt/mysql/bin/mysqladmin /usr/bin
ln -fs /opt/mysql/bin/mysql /usr/bin
3，/etc/zabbix/路径下新建.my.cnf文件
	[mysql]
	host=localhost
	user=mysqlcheck
	password=mysqlcheck
	socket=/data/mysql/mysql.sock 
	[mysqladmin]
	host=localhost
	user=mysqlcheck
	password=mysqlcheck
	socket=/data/mysql/mysql.sock
4，重启zabbix_agent，文后附录重启脚本
5，进入zabbix主服务器，测试
	cd /data/zabbix_server/bin/
	./zabbix_get -s 10.200.56.60 -p 10050 -k mysql.ping
	若一直报错Access denied for user 'root'@'localhost' (using password: NO)，没有使用我们刚创建的mysqlcheck用户
	则需要进入到/etc/zabbix/zabbix_agentd.d/目录下，修改userparameter_mysql.conf
	修改  /var/lib/zabbix 为/etc/zabbix/  
	然后重启zabbix_agentd

下面主要记录其中会出现的问题：

1，创建mysql用户

mysql -uroot -proot
GRANT USAGE ON *.* TO 'mysqlcheck'@'localhost' IDENTIFIED BY 'mysqlcheck';

若出现ERROR 1819 (HY000): Your password does not satisfy the current policy requirements，说明密码复杂度较低，可以调整mysql策略

        1.1 SHOW VARIABLES LIKE 'validate_password%'; 
        1.2 set global validate_password_policy=LOW; 
        1.3 重新执行新建用户
        1.4 set global validate_password_policy=MEDIUM;

2，出现Access denied for user 'root'@'localhost' (using password: NO)

 若一直报错Access denied for user 'root'@'localhost' (using password: NO)，没有使用我们刚创建的mysqlcheck用户
    则需要进入到/etc/zabbix/zabbix_agentd.d/目录下，修改userparameter_mysql.conf
    修改  /var/lib/zabbix 为/etc/zabbix/  
    然后重启zabbix_agentd

cd /etc/zabbix/zabbix_agentd.d/
vi userparameter_mysql.conf

 3，出现错误

mysql mysqladmin: command not found

这是由于系统默认会查找/usr/bin下的命令，如果这个命令不在这个目录下，会找不到命令，我们需要做的就是映射一个链接到/usr/bin目录下，相当于建立一个链接文件。

ln -fs /opt/mysql/bin/mysqladmin /usr/bin
ln -fs /opt/mysql/bin/mysql /usr/bin

4，重启脚本附录：

#!/bin/bash
pfurl='/usr/sbin/zabbix_agentd -c /etc/zabbix/zabbix_agentd.conf'
PID=0
kill_zabbix_agentd(){
       ps aux | awk -r '/zabbix_agentd/{print $2}' | xargs -n1 -exec kill {} &> /dev/null
}
pfstart(){
        num=`ps aux | awk -r '/zabbix_agentd/{print $2}' | wc -l`
        if [ $num != "1" ];then
                echo "zabbix_agentd is useing"
        else
                echo "zabbix_agentd is starting..."
                $pfurl
                echo "start done!"
        fi
}

if [ "$1" == "-s" ];then
        if [ "$2" == "stop" ];then
                echo "zabbix_agentd is stopping...."
                kill_zabbix_agentd
                echo "stop done!"
        elif [ "$2" == "start" ];then
                pfstart
        elif [ "$2" == "restart" ];then
                echo "zabbix_agentd is stopping...."
                kill_zabbix_agentd
                echo "stop done!"
                echo "zabbix_agentd is starting..."
                $pfurl
                echo "start done!"
        fi
elif [ "$1" == "--help" ];then
        echo "zabbix_agentd -s [start/stop/restart]"
else
        pfstart
fi
