#、（可选项）zabbix前端基本安装中不提供其他软件包，需要在运行zabbix前端的系统中启用可选rpm的存储库
[root@localhost ~]# yum-config-manager --enable rhel-7-server-optional-rpms
//2、安装Zabbix-server：
[root@localhost ~]# yum -y install zabbix-server-mysql
#、安装zabbix-Proxy（代理服务器，半分布式的，若不需要，可暂时不安装）
[root@localhost ~]# yum -y install zabbix-proxy-mysql
//3、安装zabbix-front-web
[root@localhost ~]# yum -y install zabbix-web-mysql

Install and configure the database

//4、安装Mariadb database
[root@localhost ~]# yum -y install mariadb-server
[root@localhost ~]# systemctl start mariadb.service         //启动数据库
[root@localhost ~]# msyql_secure_installation               //设置Mariadbroot初始化密码
[root@localhost ~]# mysql -uroot -p123456
MariaDB [(none)]> create database zabbix character set utf8 collate utf8_bin;  
                                    //创建数据库，名称为zabbix并且字符为utf8
MariaDB [(none)]> create user 'zabbix'@'localhost' identified by '123456'; 
                                    //创建zabbix用户并设置密码
MariaDB [(none)]> grant all privileges on zabbix.* to 'zabbix'@'localhost'; 
                                    //授权zabbix用户从localhost访问，对zabbix数据库有完全控制权限
MariaDB [(none)]> flush privileges;         //刷新权限
MariaDB [(none)]> exit                      // 退出

// 使用MySQL导入服务器的出事架构和数据； zabbix = use zabbix；切换到zabbix数据库之下
[root@localhost ~]# 
> zcat /usr/share/doc/zabbix-server-mysql*/create.sql.gz | mysql -uzabbix -p123456 zabbix
MariaDB [zabbix]> show tables；              // 查看数据导入是否成功

// 针对zabbix-server配置数据库：
[root@localhost ~]# vi /etc/zabbix/zabbix_server.conf
# LogFile=/var/log/zabbix/zabbix_server.log
DBHost=localhost        // 数据库主机
DBName=zabbix           // 数据库名称
DBUser=zabbix           // 数据库用户名
DBPassword=<password>   // 数据库密码
# DBSocket=/var/lib/mysql/mysql.sock

//5、启动zabbix-server
[root@localhost ~]# systemctl restart zabbix-server.service

Set up front-web service
//6, set up zabbix-front-web

[root@localhost ~]# vim /etc/httpd/conf.d/zabbix.conf
# php_value date.timezone Europe/Riga
  php_value date.timezone Asia/Shanghai

Restart all services:

//7、启动zabbix-server、mariadb-server、httpd服务，并设置开机自启动。
[root@localhost ~]# systemctl restart zabbix-server.service
[root@localhost ~]# systemctl enable zabbix-server.service
[root@localhost ~]# systemctl start mariadb.service
[root@localhost ~]# systemctl enable mariadb.service
[root@localhost ~]# systemctl start httpd.service
[root@localhost ~]# systemctl enable httpd.service

注意事项：关闭selinux和firewalld.service

Check whether what we have installed is normal:

通过如下命令进行效验：
[root@localhost ~]# ss -tunlp
    zabbix-server 监听端口为tcp 10051
    zabbix-agent 监听端口为tcp 10050
