1、添加清华大学软件源：
将以下内容写入 /etc/yum.repos.d/CentOS-Base.repo
# CentOS-Base.repo
#
# The mirror system uses the connecting IP address of the client and the
# update status of each mirror to pick mirrors that are updated to and
# geographically close to the client. You should use this for CentOS updates
# unless you are manually picking other mirrors.
#
# If the mirrorlist= does not work for you, as a fall back you can try the
# remarked out baseurl= line instead.
#
#
[base]
name=CentOS-$releasever - Base
baseurl=https://mirrors.tuna.tsinghua.edu.cn/centos/$releasever/os/$basearch/
#mirrorlist=http://mirrorlist.centos.org/?release=$releasever&arch=$basearch&repo=os
gpgcheck=1
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-7
#released updates

gpgcheck=1
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-7
#additional packages that extend functionality of existing packages
[centosplus]
name=CentOS-$releasever - Plus

gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-7
更新软件包缓存 sudo yum makecache
2、下载清华软件源的rpm包：
wget https://mirrors.tuna.tsinghua.edu.cn/zabbix/zabbix/4.0/rhel/7/x86_64/zabbix-server-mysql-4.0.14-1.el7.x86_64.rpm
wget https://mirrors.tuna.tsinghua.edu.cn/zabbix/zabbix/4.0/rhel/7/x86_64/zabbix-web-4.0.14-1.el7.noarch.rpm
wget https://mirrors.tuna.tsinghua.edu.cn/zabbix/zabbix/4.0/rhel/7/x86_64/zabbix-web-mysql-4.0.14-1.el7.noarch.rpm
wget https://mirrors.tuna.tsinghua.edu.cn/zabbix/zabbix/4.0/rhel/7/x86_64/zabbix-agent-4.0.14-1.el7.x86_64.rpm
wget https://mirrors.tuna.tsinghua.edu.cn/zabbix/zabbix/4.0/rhel/7/x86_64/zabbix-get-4.0.14-1.el7.x86_64.rpm
yum -y localinstall zabbix-server-mysql-4.0.14-1.el7.x86_64.rpm
yum -y localinstall zabbix-web-4.0.14-1.el7.noarch.rpm
yum -y localinstall zabbix-web-mysql-4.0.14-1.el7.noarch.rpm
yum -y localinstall zabbix-agent-4.0.14-1.el7.x86_64.rpm
yum -y localinstall zabbix-get-4.0.14-1.el7.x86_64.rpm
gunzip /usr/share/doc/zabbix-server-mysql-4.0.14/create.sql.gz
3、安装数据库mariadb并配置：
yum install mariadb mariadb-server systemctl start mariadb #启动mariadb systemctl enable mariadb #设置开机自启动 mysql_secure_installation #设置root密码等相关 mysql -uroot -p #测试登录
create database zabbix;
grant all on zabbix.* to zabbix@'127.0.0.1' identified by 'zabbix123';
source /usr/share/doc/zabbix-server-mysql-4.0.14/create.sql
vi /etc/zabbix/zabbix_server.conf
修改DBhost为127.0.0.1：
### Option: DBHost
# Database host name.
# If set to localhost, socket is used for MySQL.
# If set to empty string, socket is used for PostgreSQL.
#
# Mandatory: no
# Default:
# DBHost=localhost
DBHost=127.0.0.1
# Option: DBPassword
# Database password.
# Comment this line if no password is used.
#
# Mandatory: no
# Default:
# DBPassword=
DBPassword=zabbix123
4、启动zabbix-server agent和apache ：
systemctl start zabbix-server zabbix-agent httpd
在浏览器访问 ip/zabbix 即可进入web配置页面
