使用zabbix监控MySQL

zabbix server 192.168.100.222    

zabbix agentd 192.168.100.100

zabbix agentd端
1.添加mysql的zabbix查询帐号：
>GRANT PROCESS,SUPER,REPLICATION CLIENT ON *.* TO zabbix@'127.0.0.1' IDENTIFIED BY 'zabbix_user';  

2.编写监控mysql的脚本
# cd /usr/local/sbin/ 
# vim zabbix_mysql_check.sh 

#!/bin/sh
MYSQL_SOCK="/tmp/mysql.sock"
MYSQL_USER='zabbix'
MYSQL_PWD='zabbix_user'
MYSQL_HOST='127.0.0.1'
MYSQL_PORT='3306'
ARGS=1
if [ $# -ne "$ARGS" ];then
echo "Please input one arguement:"
fi
case $1 in
Uptime)
result=`/usr/local/mysql/bin/mysqladmin -u$MYSQL_USER -h$MYSQL_HOST -p${MYSQL_PWD} -S $MYSQL_SOCK status|cut -f2 -d":"|cut -f1 -d"T"`
echo $result
;;

result=`/usr/local/mysql/bin/mysqladmin -u$MYSQL_USER -h$MYSQL_HOST -p${MYSQL_PWD} -S $MYSQL_SOCK extended-status |grep -w "Com_update"|cut -d"|" -f3`
echo $result

echo $result
;;

result=`/usr/local/mysql/bin/mysqladmin -u$MYSQL_USER -h$MYSQL_HOST -p${MYSQL_PWD} -S $MYSQL_SOCK extended-status |grep -w "Com_select"|cut -d"|" -f3`
echo $result
;;

result=`/usr/local/mysql/bin/mysqladmin -u$MYSQL_USER -h$MYSQL_HOST -p${MYSQL_PWD} -S $MYSQL_SOCK extended-status |grep -w "Com_rollback"|cut -d"|" -f3`
echo $result
;;

echo $result
;;

result=`/usr/local/mysql/bin/mysqladmin -u$MYSQL_USER -h$MYSQL_HOST -p${MYSQL_PWD} -S $MYSQL_SOCK extended-status |grep -w "Com_insert"|cut -d"|" -f3`
echo $result
;;

result=`/usr/local/mysql/bin/mysqladmin -u$MYSQL_USER -h$MYSQL_HOST -p${MYSQL_PWD} -S $MYSQL_SOCK extended-status |grep -w "Com_delete"|cut -d"|" -f3`
echo $result

echo $result

echo $result
;;

echo $result

esac

# chmod u+x /usr/local/sbin/zabbix_check_mysql.sh 
# chown -R zabbix.zabbix /usr/local/sbin/zabbix_mysql_check.sh 

3.修改zabbix_agentd.conf文件
# vim /usr/local/zabbix/etc/zabbix_agentd.conf 
在最后添加内容:

#CHECK_MYSQL
UserParameter=mysql.version,mysql -V
UserParameter=mysql.status[*],/usr/local/sbin/zabbix_mysql_check.sh $1
UserParameter=mysql.ping,mysqladmin --defaults-file=/root/.my.cnf  ping |grep -c alive

4.mysql登录文件
#其中因为mysql 5.6不能使用明文密码登录，所以这里要创建登录配置文件
# vim /root/.my.cnf

[client]
user=zabbix
password=zabbix_user
host=127.0.0.1

5.重启zabbix agentd
# /usr/local/zabbix/sbin/zabbix_agentd stop 
# /usr/local/zabbix/sbin/zabbix_agentd 
 
zabbix server端
1.测试
# /usr/local/zabbix/bin/zabbix_get -s 192.168.100.100 -p10050 -k mysql.status[Com_update]  

469638

# /usr/local/zabbix/bin/zabbix_get -s 192.168.100.100 -p10050 -k mysql.status[Com_insert]

2.把mysql主机连接到Template App MySQL模板
