安装配置Zabbix开源监控系统用于生产环境中
运行环境：操作系统：CentOS release 6.10 (Final)
数据库：MySQL Ver 14.14 Distrib 5.5.55
Web中间件：Apache/2.2.15 (Unix)
程序语言环境：PHP 5.4.45
软件包：Zabbix 3.4
任务：安装配置Zabbix，尝试使用在生产环境中。
操作步骤：
1.安装MySQL数据库
# rpm -i https://repo.zabbix.com/zabbix/3.0/rhel/6/x86_64/zabbix-release-3.0-1.el6.noarch.rpm
2.安装Zabbix server，Web前端，agent
# yum install zabbix-server-mysql zabbix-web-mysql zabbix-agent
3.创建初始数据库
# mysql -uroot -p
password
mysql> create database zabbix character set utf8 collate utf8_bin;
mysql> grant all privileges on zabbix.* to zabbix@localhost identified by 'password';
mysql> quit;
导入初始架构和数据，系统将提示您输入新创建的密码。
#zcat /usr/share/doc/zabbix-server-mysql*/create.sql.gz | mysql -uzabbix -p zabbix
4.为Zabbix server配置数据库
编辑配置文件/etc/zabbix/zabbix_server.conf
DBPassword=password
5.为Zabbix前端配置PHP
配置时区
# pwd
/etc/httpd/conf.d
# vi php.conf
php_value date.timezone Asia/Shanghai
# vi /etc/php.ini
date.timezone =Asia/Shanghai
6.启动Zabbix server和agent进程
# service zabbix-server restart
Shutting down Zabbix server: [确定]
Starting Zabbix server: [确定]
# service zabbix-agent restart
Shutting down Zabbix agent: [确定]
Starting Zabbix agent:
7.配置Zabbix前端
# pwd
/usr/share/zabbix
# cp –rzabbix/ /var/www/html/
#如果前端无法访问zabbix,将原安装zabbix的源码位置迁移到httpd的/var/www/html目录下
连接到新安装的Zabbix前端： http://server_ip_or_name/zabbix

Since Zabbix 2.2.1, the PHP gettext extension is not a mandatory requirement for installing Zabbix. If gettext is not installed, the frontend will work as usual, however, the translations will not be available.配置php.ini参数表

相关步骤按默认导航安装即可。
配置Zabbix时要注意几个事项：
1.配置zabbix.conf.php文件
# pwd
/etc/zabbix/web
# vizabbix.conf.php
$DB['TYPE'] = 'MYSQL';
$DB['SERVER'] = 'localhost';
$DB['PORT'] = '3306';
$DB['DATABASE'] = '*****';
$DB['USER'] = '******';
$DB['PASSWORD'] = '**********';
// Schema name. Used for IBM DB2 and PostgreSQL.
$DB['SCHEMA'] = '';
$ZBX_SERVER = 'localhost';
$ZBX_SERVER_PORT = '10051';
$ZBX_SERVER_NAME = 'zabbix_server';
2.配置zabbix_agentd.conf和zabbix_server.conf两个文件
# pwd
/etc/zabbix
ServerActive=ip #启用服务IP
ListenIP=127.0.0.1 #启用监控IP
3.配置防火墙
# cat /etc/sysconfig/iptables
-A INPUT -p tcp -m state --state NEW -m tcp --dport 10051 -j ACCEPT
-A OUTPUT-p tcp -m state --state NEW -m tcp --dport 10050-j ACCEPT
以上服务器端基本配置完成，客户端在这里不做说明。

Zabbix功能强大于Cacti监控系统。
相对Cacti来讲，Zabbix配置应用更复杂。
