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:
1
|
yum -y install mysql-devel libcurl-devel net-snmp-devel |
2、添加用户:
1
2
|
groupadd zabbix useradd zabbix -g zabbix |
3、创建数据库,添加授权账号
1
2
|
create database zabbix character set utf8; grant all privileges on zabbix.* to zabbix@localhost identified by 'zabbix' ; |
4、编译安装zabbix

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
- Com_update:mysql执行的更新个数
- Com_select:mysql执行的查询个数
- Com_insert:mysql执行插入的个数
- Com_delete:执行删除的个数
- Com_rollback:执行回滚的操作个数
- Bytes_received:接受的字节数
- Bytes_sent:发送的字节数
- Slow_queries:慢查询语句的个数
1、创建mysql性能监控脚本

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
