一、简介

  1、什么是zabbix

    zabbix是一个企业级的、开源的、分布式的监控套件。

    zabbix可以对网络和服务进行完整性,健康性的监控。zabbix利用灵活的告警机制,可以实验微信,短信和邮件自动报警,zabbix利用存储的监控数据提供监控报告及实现图形化显示。

    zabbix支持主动轮询和被动捕获,zabbix所有的报告、统计信息和配置参数都可以通过基于web的前端页面可以确保您从任何方面评估您的网络状态和服务器健康性

    重要的是zabbix还是免费的。   

  2、zabbix特性    

    zabbix是一个高度集成的网络监控套件,通过一个软件包即可提供如下特性

      数据收集

        可用性和性能检查

        支持SNMP(包括捕获和主动轮训),IPMI,JMX,VMware监控

        自定义检查

        按照自定义的间隔收集需要的数据

      灵活的阈值定义

        可以非常灵活的定义问题阈值,称之为触发器,触发器从后端数据库获取参考值

      高级告警配置

        可以根据升级计划,接收方和媒体类型来定制发送告警通知,使用宏变量可以是告警通知更有意义更高效,自动化动作包含执行远程命令

      实时绘图

        使用内置图表绘制功能可以将监控项的内容立即绘制成图表

      扩展的图形化显示

        能够自定义图形,图像中可将多个监控项组合在一个视图展示

        网络拓扑图

        以仪表盘的样式展现自定义的展现和幻灯片

        报告

        监控资源高级(业务)视图

        数据存储在数据库中

        可配置历史数据

        内置数据管理机制

      配置简单

        将被监控对象添加为主机

        主机被创建用于监控,在数据库中是唯一的

        应用模板来监控设备   

      模板使用

        在模板中分组检查

        模板可以关联其他模板

      网络自动发现

6 mariadb-libs-5.5.60-1.el7_5.x86_64

  4、软件配置

   1)、配置nginx

    cat /etc/nginx/conf.d/default.conf 

 1 [root@web1 yum.repos.d]# cat /etc/nginx/conf.d/default.conf 
 2 server {
 3         listen 80;
 4         server_name 192.168.216.51;
 5         index index.html index.htm index.php;
 6         charset utf-8;
 7         root /usr/share/nginx/html;
 8 
 9         location ~.*\.php$ {
10                 fastcgi_pass unix:/dev/shm/php-fpm.sock;
11                 fastcgi_index index.php;
12                 fastcgi_param   SCRIPT_FILENAME $document_root$fastcgi_script_name;
13                 include fastcgi_params;
14                 try_files $uri = 404;
15         }
16 
17         location ~.*\.(gif|jpg|jpeg|png|bmp|swf|flv|mp3|wma)$ {
18                 expires 30d;
19         }
20         location ~.*\.(js|css)$ {
21                 expires 12h;
22         }
23 
24 
25 }

   2)、配置php-fpm

    cat /etc/php-fpm.d/www.conf

    修改下面几项

1 listen = /dev/shm/php-fpm.sock
2 listen.owner = nobody
3 listen.group = nobody
4 user = nginx
5 group = nginx

   启动nginx和php-fpm

 1 [root@web1 yum.repos.d]# systemctl start nginx 
 2 [root@web1 yum.repos.d]# systemctl start php-fpm
 3 [root@web1 yum.repos.d]# netstat -untlp |grep 80
 4 tcp        0      0 0.0.0.0:80              0.0.0.0:*               LISTEN      13408/nginx: master 
 5 tcp6       0      0 :::80                   :::*                    LISTEN      13408/nginx: master 
 6 [root@web1 yum.repos.d]# netstat -untlp |grep php*
 7 [root@web1 yum.repos.d]# ps -aux |grep php*
 8 root      14058  0.0  0.7 417184 13444 ?        Ss   00:04   0:00 php-fpm: master process (/etc/php-fpm.conf)
 9 nginx     14060  0.0  0.3 419268  6468 ?        S    00:04   0:00 php-fpm: pool www
10 nginx     14061  0.0  0.3 419268  6468 ?        S    00:04   0:00 php-fpm: pool www
11 nginx     14062  0.0  0.3 419268  6468 ?        S    00:04   0:00 php-fpm: pool www
12 nginx     14063  0.0  0.3 419268  6468 ?        S    00:04   0:00 php-fpm: pool www
13 nginx     14064  0.0  0.3 419268  6468 ?        S    00:04   0:00 php-fpm: pool www
14 root      14223  0.0  0.0 112652   968 pts/0    S+   00:18   0:00 grep --color=auto php*

    最后记得开机自启

    systemctl enable nginx

    systemctl enable php-fpm

    测试一下php,添加index.php,访问一下192.168.216.51

    

1 [root@web1 html]# pwd
2 /usr/share/nginx/html
3 [root@web1 html]# cat index.php 
4 <?php
5         phpinfo();
6 ?>
7 
8 [root@web1 html]# 

    

    没问题,进入下一步骤

    

  

   3)、配置数据库

    我们在52安装的数据库

    3.1、启动一下服务

 1 Installed:
 2   mariadb-server.x86_64 1:5.5.60-1.el7_5

 6 
 7 Complete!
 8 [root@web2 yum.repos.d]# systemctl start  mariadb
 9 [root@web2 yum.repos.d]# netstat -untlp |grep 3306
10 tcp        0      0 0.0.0.0:3306            0.0.0.0:*               LISTEN      5563/mysqld         
11 [root@web2 yum.repos.d]# systemctl enable mariadb

    3.2、创建zabbix database,zabbix账户,修改root密码

 1 [root@web2 yum.repos.d]# mysql                   #进入数据库

28 Rows matched: 4  Changed: 4  Warnings: 0
29 
30 MariaDB [mysql]> flush privileges;
31 Query OK, 0 rows affected (0.00 sec)

      3.3、51上测试连接数据

1 [root@web1 html]# mv index.php index.php.phpinfo
2 [root@web1 html]# vim index.php 
3 <?php
4         $link=mysql_connect('192.168.216.52','zabbix','admin123');
5         if($link) echo "<h1>The database connection was successful!</h1>";
6         else echo "<h1>The database connection was Fail!!</h1>";
7         mysql_close();
8 ?>

      

    3.4、导入zabbix database 数据库脚本

   4)、修改zabbix配置文件,设置权限

   vim /etc/zabbix/zabbix_server.conf

    ListenPort=10051

    DBHost=192.168.216.52

    DBName=zabbix

    DBUser=zabbix

    DBPassword=admin123

    DBPort=3306

     修改这几项应该就可以了

27 [root@web1 zabbix-server-mysql-4.0.4]# 

      最后修改nginx配置文件

    51上

    cat /etc/nginx/conf.d/default.conf 

    修改下面一项即可

    root /usr/share/zabbix;

    systemctl restart nginx

    问题1、访问192.168.216.51 出错代码500

    cat /var/log/nginx/error.log

    tail -5 /var/log/nginx/error.log

1  PHP Fatal error:  require_once(): Failed opening required '/etc/zabbix/web/maintenance.inc.php' (include_path='.:/usr/share/pear:/usr/share/php') in /usr/share/zabbix/include/classes/core/ZBase.php on line 276" while reading response header from upstream, client: 192.168.216.1, server: 192.168.216.51, request: "GET /index.php HTTP/1.1", upstream: "fastcgi://unix:/dev/shm/php-fpm.sock:", host: "192.168.216.51"

    修改权限

    

1 505 chown -R zabbix:zabbix /etc/zabbix
2 506 chown -R zabbix:zabbix /usr/share/zabbix
3 507 chown -R zabbix:zabbix /usr/lib/zabbix
4 508 chmod -R 755 /etc/zabbix/web

    访问192.168.216.51

三、正式开始web界面配置安装配置zabbix

    

   1、第一步welcome 点击下一步网页还是跳会第一步

    问题2、无法进行第2步

    有可能是php session没起作用

    修改php session 权限

    chmod -R 777 /var/lib/php/session/

   2、第二步 check of pre-requisites

      检查先决条件

  

      问题3、先把fail解决,修改php文件

      vim /etc/php.ini

      

1 post_max_size = 32M
2 
3 max_execution_time = 300
4 
5 max_input_time = 300
6 
7 date.timezone = PRC

      systemctl restart php-fpm

      访问一下,好了,进行下一步,点击next step

    

   3、configure DB connection

    配置连接的数据库

  

      问题4、点击nextstep 出错,上一篇也遇到了这个问题

  

       查看nginx日志发现

1 [root@web1 share]# !tail
2 tail -5 /var/log/nginx/error.log

8 [root@web1 share]# vim /etc/nginx/conf.d/default.conf 

    

    upstream sent too big header while reading response header from upstream
    是这个问题导致,在网站找好多方法,都不行,最后看到是因为fastcgi缓冲区设置过小,其实是header过大
    添加缓存区解决,编辑nginx 配置文件,添加两项
    fastcgi_buffers 8 16k;
    fastcgi_buffer_size 32k;
 1 [root@web1 share]# vim /etc/nginx/conf.d/default.conf 
 2

12                 #fail_timeout=60;
13                 root /usr/share/zabbix;
14         }
15 
16         location ~.*\.php$ {
17                 fastcgi_connect_timeout 300;

34         location ~.*\.(js|css)$ {
35                 expires 12h;
36         }
37 
38
