安装配置Zabbix来监控MySQL的基本教程

Zabbix的简单安装配置说明
1、在已有的LAMP或者LNMP的基础上安装zabbix，安装一些依赖包：

yum -y install mysql-devel libcurl-devel net-snmp-devel

2、添加用户：

groupadd zabbix
useradd zabbix -g zabbix

3、创建数据库，添加授权账号

create database zabbix character set utf8;
grant all privileges on zabbix.* to zabbix@localhost identified by 'zabbix';

4、编译安装zabbix
   下载地址：

wget http://jaist.dl.sourceforge.net/project/zabbix/ZABBIX%20Latest%20Stable/2.2.0/zabbix-2.2.0.tar.gz
tar zxf zabbix-2.2.0.tar.gz
cd zabbix-2.2.0
./configure --prefix=/usr/local/zabbix --enable-server --enable-agent \
--with-mysql --with-net-snmp --with-libcurl
make install

5、导入数据库

mysql -uzabbix -pzabbix -hlocalhost zabbix < database/mysql/schema.sql
mysql -uzabbix -pzabbix -hlocalhost zabbix < database/mysql/images.sql
mysql -uzabbix -pzabbix -hlocalhost zabbix < database/mysql/data.sql

6、修改配置文件

cp misc/init.d/fedora/core/zabbix_server /etc/init.d/
cp misc/init.d/fedora/core/zabbix_agentd /etc/init.d/
cp -R frontends/php /var/www/html/zabbix
sed -i 's/^DBUser=.*$/DBUser=zabbix/g' /usr/local/zabbix/etc/zabbix_server.conf
sed -i 's/^.*DBPassword=.*$/DBPassword=zabbix/g' /usr/local/zabbix/etc/zabbix_server.conf
sed -i 's/BASEDIR=\/usr\/local/BASEDIR=\/usr\/local\/zabbix/g' /etc/init.d/zabbix_server
sed -i 's/BASEDIR=\/usr\/local/BASEDIR=\/usr\/local\/zabbix/g' /etc/init.d/zabbix_agentd

7、添加服务端口：

cat >>/etc/services <<EOF
zabbix-agent 10050/tcp Zabbix Agent
zabbix-agent 10050/udp Zabbix Agent
zabbix-trapper 10051/tcp Zabbix Trapper
zabbix-trapper 10051/udp Zabbix Trapper
EOF

8、启动服务

/etc/init.d/zabbix_server start
/etc/init.d/zabbix_agentd start
echo "/etc/init.d/zabbix_server start" >> /etc/rc.local
echo "/etc/init.d/zabbix_agentd start" >> /etc/rc.local

9、web页面配置，配置http访问好了后web登陆：http://ip/zabbix

zabbix监控mysql性能
通过获取mysql状态值将这些状态值传递给服务器并绘制成图片，这样可以观察mysql的工作情况，通常需要获得状态变量有以下

1、创建mysql性能监控脚本

#!/bin/bash
#Create by zhengdazhi 2014.09.22
MYSQL_DIR=/usr/local/mysql
MYSQL=${MYSQL_DIR}/bin/mysql
MYSQLADMIN=${MYSQL_DIR}/bin/mysqladmin
MYSQL_SOCK="/tmp/mysql.sock"
MYSQL_USER=root
MYSQL_PWD=root
 
ARGS=1 
if [ $# -ne "$ARGS" ];then 
 echo "Please input one arguement:" 
fi 
case $1 in 
 Uptime) 
 result=`${MYSQLADMIN} -u${MYSQL_USER} -p${MYSQL_PWD} -S $MYSQL_SOCK status|cut -f2 -d":"|cut -f1 -d"T"` 
 echo $result 
 ;; 
 Com_update) 
 result=`${MYSQLADMIN} -u${MYSQL_USER} -p${MYSQL_PWD} -S $MYSQL_SOCK extended-status |grep -w "Com_update"|cut -d"|" -f3` 
 echo $result 
 ;; 
 Slow_queries) 
 result=`${MYSQLADMIN} -u${MYSQL_USER} -p${MYSQL_PWD} -S $MYSQL_SOCK status |cut -f5 -d":"|cut -f1 -d"O"` 
 echo $result 
 ;; 
 Com_select) 
 result=`${MYSQLADMIN} -u${MYSQL_USER} -p${MYSQL_PWD} -S $MYSQL_SOCK extended-status |grep -w "Com_select"|cut -d"|" -f3` 
 echo $result 
 ;; 
 Com_rollback) 
 result=`${MYSQLADMIN} -u${MYSQL_USER} -p${MYSQL_PWD} -S $MYSQL_SOCK extended-status |grep -w "Com_rollback"|cut -d"|" -f3` 
 echo $result 
 ;; 
 Questions) 
 result=`${MYSQLADMIN} -u${MYSQL_USER} -p${MYSQL_PWD} -S $MYSQL_SOCK status|cut -f4 -d":"|cut -f1 -d"S"` 
 echo $result 
 ;; 
 Com_insert) 
 result=`${MYSQLADMIN} -u${MYSQL_USER} -p${MYSQL_PWD} -S $MYSQL_SOCK extended-status |grep -w "Com_insert"|cut -d"|" -f3` 
 echo $result 
 ;; 
 Com_delete) 
 result=`${MYSQLADMIN} -u${MYSQL_USER} -p${MYSQL_PWD} -S $MYSQL_SOCK extended-status |grep -w "Com_delete"|cut -d"|" -f3` 
 echo $result 
 ;; 
 Com_commit) 
 result=`${MYSQLADMIN} -u${MYSQL_USER} -p${MYSQL_PWD} -S $MYSQL_SOCK extended-status |grep -w "Com_commit"|cut -d"|" -f3` 
 echo $result 
 ;; 
 Bytes_sent) 
 result=`${MYSQLADMIN} -u${MYSQL_USER} -p${MYSQL_PWD} -S $MYSQL_SOCK extended-status |grep -w "Bytes_sent" |cut -d"|" -f3` 
 echo $result 
 ;; 
 Bytes_received) 
 result=`${MYSQLADMIN} -u${MYSQL_USER} -p${MYSQL_PWD} -S $MYSQL_SOCK extended-status |grep -w "Bytes_received" |cut -d"|" -f3` 
 echo $result 
 ;; 
 Com_begin) 
 result=`${MYSQLADMIN} -u${MYSQL_USER} -p${MYSQL_PWD} -S $MYSQL_SOCK extended-status |grep -w "Com_begin"|cut -d"|" -f3` 
 echo $result 
 ;; 
 
 *) 
 echo "Usage:$0(Uptime|Com_update|Slow_queries|Com_select|Com_rollback|Questions)" 
 ;; 
esac

2、修改客户端配置文件
查看zabbix自带的mysql监控模板

可以看出该模板是读取 mysql.status的键，因此在客户端配置文件中加入的自定义键名也应该是mysql.status

vim /usr/local/zabbix_agentd/etc/zabbix_agentd.conf
#开启用户自定义配置
UnsafeUserParameters=1
#添加mysql监控
UserParameter=mysql.status[*],/usr/local/zabbix_agent/bin/checkmysqlperformance.sh $1 $2

重启客户端
3、测试

[root@localhost bin]# ./zabbix_get -s 127.0.0.1 -k mysql.status[Com_update]
77503

4、将模板加入主机
