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
