Centos 7 搭建 Zabbix

背景不多说，直接上干货！

Zabbix-Server端：

关闭SELinux

[root@localhost ~]# setenforce 0        //临时修改，重启失效修改配置文件：/etc/selinux/configSELINUX=enforcing   改成  SELINUX= disabled

关闭防火墙

[root@localhost ~]# systemctl stop firewalld            //关闭防火墙[root@localhost ~]# systemctl disable firewalld          //开机不启动防火墙

删除原来配置的yum源

[root@localhost ~]# rm -rf /etc/yum.repos.d/*         //删除其他yum源

配置阿里云 yum源

[root@localhost ~]# vi /etc/yum.repos.d/zabbix.repo[os]name=osbaseurl=https://mirrors.aliyun.com/centos/7/os/x86_64/gpgcheck=0enabled=1[non-supported]name=non-supportedbaseurl=https://mirrors.aliyun.com/zabbix/non-supported/rhel/7/x86_64/gpgcheck=0enabled=1[zabbix]name=zabbix 3.2baseurl=https://mirrors.aliyun.com/zabbix/zabbix/3.2/rhel/7/x86_64/gpgcheck=0enabled=1

重新缓存yum源

[root@localhost ~]yum clean all[root@localhost ~]yum repolist

安装zabbix-server

[root@localhost ~]# yum install -y zabbix-server-mysql zabbix-web-mysql

安装数据库

[root@localhost ~]# yum groupinstall -y mariadb mariadb-client

修改/etc/my.cnf

在[mysqld]下添加character-set-server=utf8    ##设置字符集innodb_file_per_table=1      ##让innodb每个表文件单独存放

启动mariadb数据库

[root@localhost ~]# systemctl enable mariadb

[root@localhost ~]# systemctl start mariadb

交互式界面初始化数据库

[root@localhost ~]# mysql_secure_installation 

创建zabbix库

MariaDB [(none)]> create database zabbix character set utf8 collate utf8_bin;      ##创库时设置好字符集问题

创建数据库用户及配置用户权限

MariaDB [(none)]> grant all privileges on zabbix.* to zabbix@localhost identified by 'redhat';

重载权限表

MariaDB [(none)]> flush privileges;

查找数据库文件

[root@localhost ~]# rpm -ql zabbix-server-mysql/usr/share/doc/zabbix-server-mysql-3.2.4/create.sql.gz

解压（可用file 查看文件类型）

[root@localhost zabbix-server-mysql-3.2.4]# gzip -d create.sql.gz

导入

[root@localhost zabbix-server-mysql-3.2.4]# mysql -uroot -predhat          ##登录数据库MariaDB [(none)]> use zabbix;                                              ##切换到zabbix库MariaDB [zabbix]> source create.sql                                        ##导入数据，当前路径为进数据库时使用的路径

修改zabbix配置文件（zabbix_server.conf）

[root@localhost zabbix-server-mysql-3.2.4]# vi /etc/zabbix/zabbix_server.conf

DBName=zabbixDBUser=zabbixDBPassword=redhatDBSocket=/var/lib/mysql/mysql.sock

启动 zabbix-server

[root@localhost zabbix-server-mysql-3.2.4]# systemctl enable zabbix-server[root@localhost zabbix-server-mysql-3.2.4]# systemctl start zabbix-server

启动失败，查看日志显示

[root@localhost ~]# journalctl -xn-- Logs begin at Fri 2017-04-21 03:56:34 CST, end at Fri 2017-04-21 04:50:18 CST. --Apr 21 04:50:08 localhost.localdomain systemd[1]: zabbix-server.service: control process exited, code=killed status=11Apr 21 04:50:08 localhost.localdomain systemd[1]: Failed to start Zabbix Server.-- Subject: Unit zabbix-server.service has failed-- Defined-By: systemd-- Support: http://lists.freedesktop.org/mailman/listinfo/systemd-devel-- -- Unit zabbix-server.service has failed.-- -- The result is failed.Apr 21 04:50:08 localhost.localdomain systemd[1]: Unit zabbix-server.service entered failed state.Apr 21 04:50:18 localhost.localdomain systemd[1]: zabbix-server.service holdoff time over, scheduling restart.Apr 21 04:50:18 localhost.localdomain systemd[1]: Stopping Zabbix Server...-- Subject: Unit zabbix-server.service has begun shutting down-- Defined-By: systemd-- Support: http://lists.freedesktop.org/mailman/listinfo/systemd-devel-- -- Unit zabbix-server.service has begun shutting down.Apr 21 04:50:18 localhost.localdomain systemd[1]: Starting Zabbix Server...-- Subject: Unit zabbix-server.service has begun with start-up-- Defined-By: systemd-- Support: http://lists.freedesktop.org/mailman/listinfo/systemd-devel-- -- Unit zabbix-server.service has begun starting up.Apr 21 04:50:18 localhost.localdomain kernel: zabbix_server[2393]: segfault at 18 ip 00007fd42784dc00 sp 00007ffffedf7868 error 4 in libpthread-2.17.so[7fd4278Apr 21 04:50:18 localhost.localdomain systemd[1]: zabbix-server.service: control process exited, code=killed status=11Apr 21 04:50:18 localhost.localdomain systemd[1]: Failed to start Zabbix Server.-- Subject: Unit zabbix-server.service has failed-- Defined-By: systemd-- Support: http://lists.freedesktop.org/mailman/listinfo/systemd-devel-- -- Unit zabbix-server.service has failed.-- -- The result is failed.Apr 21 04:50:18 localhost.localdomain systemd[1]: Unit zabbix-server.service entered failed state.

这是由于trousers版本过低导致，升级trousers

yum update trousers

在此启动 zabbix-server

root@localhost ~]# systemctl start zabbix-server

修改时区

[root@localhost ~]# vi /etc/httpd/conf.d/zabbix.conf 

Alias /zabbix /usr/share/zabbix<Directory "/usr/share/zabbix">    Options FollowSymLinks    AllowOverride None        # php_value date.timezone Europe/Riga                   ##删掉注释符，修改时区为 Asia/Shanghai    </IfModule></Directory>

重启Apache

[root@localhost ~]# systemctl restart httpd

在浏览器中打开URL（IP为server端地址）

http://192.168.0.104/zabbix/

按照提示填写相关信息

右边显示的OK必须全部OK方可下一步，否则检查环境是否出错

数据库信息

服务端信息：Host填hostname或IP地址，端口为服务端开放的zabbix端口（默认10051），Name为自定义名称

安装概述

安装完成

登录用户名为Admin，密码为zabbix

登录之后的界面

client端（zabbix-agent）

客户端安装代理

yum install -y zabbix-agent

修改配置文件 zabbix_agentd.conf

Server=192.168.0.104         //被动模式，服务器取数据ServerActive=192.168.0.104:10051          //主动模式，主动向服务器监听端口推送数据Hostname=Client01             //可与本机hostname不一样

开启代理服务

[root@client ~]#systemctl enable zabbix-agent[root@client ~]#systemctl start zabbix-agent

Server端通过前台页面添加Client

完成后记得点Add按钮

在仪表盘页面可以看到新添加的主机Client
