zabbix是一个基于WEB界面,提供分布式系统监视以及网络监视功能的企业级开源解决方案。 zabbix能监视各种网络参数,保证服务器系统的安全运行;并提供灵活的通知机制以让系统管理员快速定位/解决存在的各种问题。 zabbix由2部分构成,zabbix server与可选组件zabbix agent。 zabbix server可以通过SNMP,zabbix agent,ping,端口监视等方法提供对远程服务器/网络状态的监视,数据收集等功能,它可以运行在Linux,Solaris,HP-UX,AIX,Free BSD,Open BSD,OS X等平台上
下面介绍CentOS7下Zabbix监控平台的搭建
一、安装MariaDB
yum -y install centos-release-scl-rh centos-release-scl
yum --enablerepo=centos-sclo-rh -y install rh-mariadb102-mariadb-server
[root@zabbix ~]# scl enable rh-mariadb102 bash
[root@zabbix ~]# mysql -V
mysql Ver 15.1 Distrib 10.2.22-MariaDB, for Linux (x86_64) using EditLine wrapper
[root@zabbix ~]# which mysql
/opt/rh/rh-mariadb102/root/usr/bin/mysql
[root@zabbix ~]#
[root@zabbix ~]# vi /etc/profile.d/rh-mariadb102.sh
#!/bin/bash
source /opt/rh/rh-mariadb102/enable
export X_SCLS="`scl enable rh-mariadb102 'echo $X_SCLS'`"
vi /etc/opt/rh/rh-mariadb102/my.cnf.d/mariadb-server.cnf
添加character-set-server=utf8
[root@zabbix ~]# systemctl start rh-mariadb102-mariadb
[root@zabbix ~]# systemctl enable rh-mariadb102-mariadb
进行数据库的初始化
[root@zabbix ~]# mysql_secure_installation
验证数据库是否安装成功
如果有防火墙
[root@zabbix ~]# firewall-cmd --add-service=mysql --permanent
[root@zabbix ~]# firewall-cmd --reload
二、安装Zabbix-Server
1)安装zabbix-release-4.2-2.el7.noarch.rpm
rpm -Uvh https://repo.zabbix.com/zabbix/4.2/rhel/7/x86_64/zabbix-release-4.2-2.el7.noarch.rpm
2)yum -y install zabbix-server-mysql zabbix-web-mysql zabbix-agent
3)初始化数据库,创建zabbix用户以及zabbix数据库
[root@zabbix ~]# mysql -uroot -p
Enter password:

MariaDB [(none)]> create database zabbix character set utf8 collate utf8_bin;

Query OK, 0 rows affected (0.00 sec)

4)导入zabbix表数据
cd /usr/share/doc/zabbix-server-mysql-4.2.5/
gzip -d create.sql.gz
mysql -uzabbix -p zabbix < create.sql
5)修改配置zabbix_server.conf 文件及/etc/httpd/conf.d/zabbix.conf配置文件
vi /etc/zabbix/zabbix_server.conf
DBHost=localhost
DBPassword=Admin@123(数据库的密码)
vi /etc/httpd/conf.d/zabbix.conf,修改时区
6)启动zabbix-server zabbix-agent httpd服务,并设为开机自启动
[root@zabbix ~]# systemctl restart zabbix-server zabbix-agent httpd
[root@zabbix ~]# systemctl enable zabbix-server zabbix-agent httpd
7)进行Web初始化
初始的账号Admin,密码zabbix
三、Agent的安装,监控资源的添加
以CentOS6.9的一台主机为例
1)rpm -ivh 安装agent
rpm -ivh zabbix-agent-4.2.5-1.el6.x86_64.rpm
2)修改配置文件,指定Server的IP
vi /etc/zabbix/zabbix_agentd.conf
Server=10.20.10.93
ServerActive=10.20.10.93
3)启用agent并设置agent服务开机自启动
[root@localhost ~]# service zabbix-agent start
Starting Zabbix agent: [ OK ]
[root@localhost ~]# chkconfig zabbix-agent on
[root@localhost ~]# chkconfig zabbix-agent --list
zabbix-agent 0:off 1:off 2:on 3:on 4:on 5:on 6:off
4)Zabbix Web管理界面上添加主机,设置模板
5)验证效果,例如查看网口流量信息
