安裝配置Zabbix來監控MySQL的基本教程

Zabbix的簡單安裝配置說明
1、在已有的LAMP或者LNMP的基礎上安裝zabbix，安裝一些依賴包：

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

2、添加用戶：

groupadd zabbix
useradd zabbix -g zabbix

3、創建數據庫，添加授權賬號

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

4、編譯安裝zabbix
   下載地址：

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、導入數據庫

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、添加服務端口：

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、啟動服務

/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頁面配置，配置http訪問好了後web登陸：http://ip/zabbix

zabbix監控mysql性能
通過獲取mysql狀態值將這些狀態值傳遞給服務器並繪制成圖片，這樣可以觀察mysql的工作情況，通常需要獲得狀態變量有以下

• Com_update：mysql執行的更新個數
• Com_select：mysql執行的查詢個數
• Com_insert：mysql執行插入的個數
• Com_delete：執行刪除的個數
• Com_rollback：執行回滾的操作個數
• Bytes_received:接受的字節數
• Bytes_sent：發送的字節數
• Slow_queries：慢查詢語句的個數

1、創建mysql性能監控腳本

#!/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、修改客戶端配置文件
查看zabbix自帶的mysql監控模板

可以看出該模板是讀取 mysql.status的鍵，因此在客戶端配置文件中加入的自定義鍵名也應該是mysql.status

vim /usr/local/zabbix_agentd/etc/zabbix_agentd.conf
#開啟用戶自定義配置
UnsafeUserParameters=1
#添加mysql監控
UserParameter=mysql.status[*],/usr/local/zabbix_agent/bin/checkmysqlperformance.sh $1 $2

重啟客戶端
3、測試

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

4、將模板加入主機
