组件：


zabbix-server	192.168.11.160	服务端 zabbix-server-mysql
zabbix-server-db	192.168.11.161	数据库 mariadb-server.x86_64 mariadb.x86_64
zabbix-ui	192.168.11.162	前端 zabbix-web-mysql-scl zabbix-nginx-conf-scl
zabbix-server-proxy	192.168.11.163	代理 zabbix-agent2.x86_64

[root@riyimei ~]# uname  -ra
Linux riyimei 3.10.0-1062.el7.x86_64 #1 SMP Wed Aug 7 18:08:02 UTC 2019 x86_64 x86_64 x86_64 GNU/Linux
[root@riyimei ~]# cat /etc/redhat-release 
CentOS Linux release 7.7.1908 (Core)
[root@riyimei ~]#

a. 安装 数据库
# rpm -Uvh https://repo.zabbix.com/zabbix/5.0/rhel/7/x86_64/zabbix-release-5.0-1.el7.noarch.rpm
# yum clean all
b. Install Zabbix server and agent
# yum install zabbix-server-mysql zabbix-agent
c. Install Zabbix frontend
Enable Red Hat Software Collections
# yum-config-manager --enable rhel-server-rhscl-7-rpms
编辑配置文件 /etc/yum.repos.d/zabbix.repo and enable zabbix-frontend repository.
[zabbix-frontend]
...
enabled=1
...
Install Zabbix frontend packages.
# yum install zabbix-web-mysql-scl zabbix-nginx-conf-scl
d. 创建初始数据库
在数据库主机上运行以下代码。
# mysql -uroot -p
password
mysql> create database zabbix character set utf8 collate utf8_bin;
mysql> create user zabbix@localhost identified by 'password';
mysql> grant all privileges on zabbix.* to zabbix@localhost;
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
e. 为Zabbix server配置数据库
编辑配置文件 /etc/zabbix/zabbix_server.conf
DBPassword=password
f. 为Zabbix前端配置PHP
编辑配置文件 /etc/opt/rh/rh-nginx116/nginx/conf.d/zabbix.conf, uncomment and set 'listen' and 'server_name' directives.
# listen 80;
# server_name example.com;
编辑配置文件 /etc/opt/rh/rh-php72/php-fpm.d/zabbix.conf, add nginx to listen.acl_users directive.
listen.acl_users = apache,nginx
Then uncomment and set the right timezone for you.
; php_value[date.timezone] = Europe/Riga
g. 启动Zabbix server和agent进程
启动Zabbix server和agent进程，并为它们设置开机自启：
# systemctl restart zabbix-server zabbix-agent rh-nginx116-nginx rh-php72-php-fpm
# systemctl enable zabbix-server zabbix-agent rh-nginx116-nginx rh-php72-php-fpm
h. 配置Zabbix前端
连接到新安装的Zabbix前端： http://server_ip_or_name
根据Zabbix文件里步骤操作： Installing frontend

1 安装server端

yum install zabbix-server-mysql -y

2 安装数据库

yum install mariadb-server.x86_64 mariadb.x86_64 -y

3 安装前端

~~yum install yum-utils -y~~
~~yum-config-manager —enable rhel-server-rhscl-7-rpms~~
~~yum install zabbix-web-mysql-scl zabbix-nginx-conf-scl~~
修改yum源
