Migrating Zabbix Web Frontend from Apache to Nginx

The original Zabbix deployment used a LAMP stack with Apache httpd, which runs in a single‑threaded mode and consumes high CPU when many hosts are added; switching to Nginx reduces resource usage.

Step 1: Install Nginx and PHP‑FPM

[root@zabbix ~]# yum -y install php-fpm

[root@zabbix ~]# tar -xvf nginx-1.20.2.tar.gz -C /usr/local/src/

[root@zabbix ~]# cd /usr/local/src/nginx-1.20.2

[root@zabbix ~]# ./configure --prefix=/usr/local/nginx --with-http_stub_status_module --with-http_ssl_module

[root@zabbix ~]# make && make install

Step 2: Configure Nginx

Replace the Apache configuration ( /etc/httpd/conf.d/zabbix.conf ) with an Nginx server block. Example configuration:

server {
    listen       80;
    server_name  localhost;
    location /zabbix {
        alias   /usr/share/zabbix;
        index   index.html index.htm index.php;
    }
    location ^~ /conf { deny all; }
    location ^~ /app { deny all; }
    location ^~ /include { deny all; }
    location ^~ /local { deny all; }
    error_page   500 502 503 504  /50x.html;
    location = /50x.html { root   /usr/share/nginx/html; }
    location ~ ^/zabbix/.+\.php$ {
        fastcgi_pass   127.0.0.1:9000;
        fastcgi_index  index.php;
        fastcgi_param  SCRIPT_FILENAME  /usr/share$fastcgi_script_name;
        include        fastcgi_params;
    }
}

Step 3: Restart Services

[root@zabbix ~]# systemctl start php-fpm

[root@zabbix ~]# systemctl restart nginx

[root@zabbix ~]# systemctl restart zabbix-server

Step 4: Verify and Fix Timezone

After accessing the Zabbix UI, an error appears because the PHP timezone is not set. Edit /etc/php.ini to uncomment and set the timezone:

date.timezone = Asia/Shanghai

Restart PHP‑FPM if necessary, then the Zabbix web interface works under Nginx.
