zabbix添加mysql监控：
1、建立hosts、关联mysql模板
虽然zabbix有mysql的监控模板，但是也需要在mysql服务器上准备获取mysql status的脚本chk_mysql.sh，zabbix通过调用这个脚本来获取mysql的运行信息。
2、配置zabbix_agent
vim /etc/zabbix/zabbix_agentd.conf
UserParameter=mysql.version,mysql -V
UserParameter=mysql.status[*],/usr/local/zabbix/scripts/chk_mysql.sh $1
UserParameter=mysql.ping,mysqladmin -uzabbix -p123456 -P3306 -h127.0.0.1 ping | grep -c alive
3、数据库添加账号：
mysql -uroot -p
GRANT PROCESS,SUPER,REPLICATION CLIENT ON *.* TO zabbix@'127.0.0.1' IDENTIFIED BY '123456';
4、写check脚本
mkdir -p /usr/local/zabbix/scripts
vim /usr/local/zabbix/scripts/chk_mysql
#!/bin/sh
MYSQL_SOCK="/usr/local/mysql/mysql.sock"
MYSQL_USER='zabbix'
MYSQL_PWD='123456'
MYSQL_HOST='127.0.0.1'
MYSQL_PORT='3306'
ARGS=1
if [ $# -ne "$ARGS" ];then
echo "Please input one arguement:"
fi
case $1 in

esac
别忘了脚本授权：
chmod u+x /usr/local/zabbix/chk_mysql.sh
chown -R zabbix.zabbix /usr/local/zabbix/chk_mysql.sh
脚本准备完后，重启agent
5、验证
在zabbix-server服务器上测试是否可以获取到mysql的status信息：
zabbix_get -s 127.0.0.1 -p10050 -k mysql.status[Com_update]
有结果就是ok的！
PS：zabbix_get命令：
zabbix_get -s 10.8.95.74 -p10050 -k "system.cpu.load[all,avg15]";
6、图示
zabbix自带模版默认有2个性能图，这些图要等运行一段时间后才能画出来
