一、系统环境

cat /etc/redhat-release

CentOS Linux release 7.1.1503 (Core)

关闭防火墙及selinux

systemctl stop firewalld.service

systemctl disable firewalld.service

sed -i 's/SELINUX=enforcing/SELINUX=disabled/' /etc/selinux/config

grep SELINUX=disabled /etc/selinux/config

setenforce 0

Zabbix 官方命令安装步骤：

a. Install Repository with MySQL database

rpm -i

b. Install Zabbix server, frontend, agent

yum install zabbix-server-mysql zabbix-web-mysql zabbix-agent

c. Create initial database

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;

Import initial schema and data. You will be prompted to enter your newly created password.

zcat /usr/share/doc/zabbix-server-mysql*/create.sql.gz | mysql -uzabbix -p zabbix

d. Configure the database for Zabbix server

Edit file /etc/zabbix/zabbix_server.conf

DBPassword=password

e. Configure PHP for Zabbix frontend

Edit file /etc/httpd/conf.d/zabbix.conf, uncomment and set the right timezone for you.

php_value date.timezone Europe/Riga【Aisa/Shanghai】

f. Start Zabbix server and agent processes

Start Zabbix server and agent processes and make it start at system boot:

systemctl restart zabbix-server zabbix-agent httpd

systemctl enable zabbix-server zabbix-agent httpd

Connect to your newly installed Zabbix frontend:

Follow steps described in Zabbix documentation: Installing frontend []

二、数据库安装及配置

1、MariaDB概述

MariaDB数据库管理系统是MySQL的一个分支，MariaDB的目的是完全兼容MySQL，包括API和命令行

2、安装mariadb

yum install mariadb-server mariadb -y

mariadb数据库的相关命令是：

systemctl start mariadb #启动MariaDB

systemctl stop mariadb #停止MariaDB

systemctl restart mariadb #重启MariaDB

systemctl enable mariadb #设置开机启动

安装MySQL

1.下载 Mysql yum包

wget

2.安转软件源

sudo rpm -Uvh mysql57-community-release-el7-10.noarch.rpm

3安装mysql服务端

yum install -y mysql-community-server 【时间较长越10-20分钟】

4首先启动mysql

systemctl status mysqld.service / service mysqld start

如使用mysql -u root -p 报错ERROR 1045 (28000): Access denied for user 'root'@'localhost' (using password:yes)

则：

systemctl stop mysqld.service

修改 /etc/my.cnf 在最后加上，skip-grant-tables

mysql -u root 【不要用P已经跳过密码了】

UPDATE user SET Password=PASSWORD('newpassword') where USER='root';

删除my.cnf中的skip-grant-tables 重启mysql

systemctl start/stop mysqld.service

2、Zabbix3.4安装

rpm -ivh

yum install zabbix-server-mysql zabbix-web-mysql zabbix-agent -y

3、创建数据库

create database zabbix character set utf8 collate utf8_bin;

grant all privileges on zabbix.* to zabbix@localhost identified by 'zabbix';

Zabbix 命令报错：

mysql> create database zabbix character set utf8 collate utf8_bin;

ERROR 1820 (HY000): You must reset your password using ALTER USER statement

mysql> set password=password("复杂密码"); 【不改策略有密码复杂度】

重启mysql

4、导入数据

zcat /usr/share/doc/zabbix-server-mysql-3.4.0/create.sql.gz | mysql -uzabbix -p zabbix

【让你输入的密码是之前创建的复杂密码】

Start Zabbix server and agent processes

systemctl restart zabbix-server zabbix-agent httpd

systemctl enable zabbix-server zabbix-agent httpd

5、配置数据库用户及密码

/etc/zabbix/zabbix_server.conf

DBPassword=password【之前创建的复杂密码】

/etc/httpd/conf.d/zabbix.conf

php_value date.timezone Asia/Shanghai【上海4.0可用，3.4是Aisa/Chongqing 上海有问题好像】

6、启动zabbix server并设置开机启动

systemctl enable zabbix-server

systemctl start zabbix-server

8、SELinux配置

setsebool -P httpd_can_connect_zabbix on

setsebool -P httpd_can_network_connect_db on

9、启动httpd并设置开机启动

systemctl start httpd

systemctl enable httpd

Date.timezone 过不了

解决方法：

查看php.ini配置文件的设置

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

进入后有server not run

cannot set resource limit: [13] Permission denied

setenforce 0

开启zabbix-server服务 ok

systemctl start zabbix-server

外部地址无法访问，只能本机访问zabbix

开启端口
firewall-cmd --zone=public --add-port=80/tcp --permanent
命令含义：
--zone #作用域
--add-port=80/tcp #添加端口，格式为：端口/通讯协议
--permanent #永久生效，没有此参数重启后失效
重启防火墙
firewall-cmd --reload
