How to configure Nginx reverse proxy with CPanel in CentOS 7

Guide

Nginx is one of the fastest and most powerful WEB servers, known for its high performance and low resource usage. It can be installed either as a standalone Web server or as a reverse proxy Web server. In this article, I will discuss installing Nginx as an Apache reverse proxy server on a Centos 7 server with the CPanel management system installed. Nginx serves as a front-end server with a reverse proxy for static files, and Apache serves as a backend for dynamic files. This setting will improve the performance of the server as a whole.

Let's go through the installation process of configuring Nginx as a reverse proxy on a CentOS 7 x86_64 server that already has CPanel 11.52 installed.

First, we need to install the EPEL library to start this process

First step: Install the EPEL library

[Email protected] [/usr]# yum-y Install epel-releaseloaded plugins:fastestmirror, tsflags, universal-hooksloading mirror speeds from cache D hostfile* ea4:66.23.237.210* base:mirrors.linode.com* extras:mirrors.linode.com* updates: Mirrors.linode.comResolving dependencies--> Running Transaction Check---> Package epel-release.noarch 0:7-5 would Be installed--> finished Dependency resolutiondependencies resolved============================================= =========================================== Package    Arch Version Repository size============================== ==========================================================installing:epel-release noarch 7-5 Extras k

Step Two: Install the Ndeploy centos RPM library to install the Ndeploy centos RPM library to install the Ndeploy Web-class software and Nginx plugin we need

[Email protected] [/usr]# yum-y install http://rpm.piserve.com/nDeploy-release-centos-1.0-1.noarch.rpmLoaded plugins:fastestmirror, Tsflags, universal-hooksndeploy-release-centos-1.0-1.noarch.rpm | 1.7 KB 00:00:00examining/var/tmp/yum-root-ei5twj/ndeploy-release-centos-1.0-1.noarch.rpm: ndeploy-release-centos-1.0-1.noarchmarking/var/tmp/yum-root-ei5twj/ndeploy-release-centos-1.0-1.noarch.rpm to be Installedresolving dependencies--> Running Transaction Check---> Package ndeploy-release-centos.noarch 0:1.0-1 'll be installed--> finished Dependency resolutiondependencies resolved========================================= ===============================================package Arch Version Repository size=============================== =========================================================installing:ndeploy-release-centos Noarch 1.0-1/ Ndeploy-release-centos-1.0-1.noarch 110

Step three: Install Ndeploy and Nginx Ndeploy plugin

[Email protected] [/usr]# yum--enablerepo=ndeploy install Nginx-ndeploy ndeployloaded plugins:fastestmirror, Tsflags, Universal-hooksepel/x86_64/metalink | 9.9 KB 00:00:00epel | 4.3 KB 00:00:00ndeploy | 2.9 KB 00:00:00 (quarter): ndeploy/7/x86_64/primary_db | KB 00:00:00 (2/4): Epel/x86_64/group_gz | 169 KB 00:00:00 (3/4): epel/x86_64/primary_db | 3.7 MB 00:00:02dependencies resolved============================================================================= ===========package Arch Version Repository size=================================================================== =====================installing:ndeploy noarch 2.0-11.el7 ndeploy knginx-ndeploy x86_64 1.8.0-34.el7 NDeploy 36 Minstalling for Dependencies:pyyaml x86_64 3.10-11.el7 Base 153 klibevent x86_64 2.0.21-4.EL7 Base 214 kmemcached x86_64 1 .4.15-9.EL7 base kpython-inotify noarch 0.9.4-4.el7 base kpython-lxml x86_64 3.2.1-4.EL7 Base ry========================================================================================install 2 Packages (+5 Dependent Packages) 

Through these steps, we have completed the installation of Nginx plugin on our server. Now we can configure Nginx as a reverse proxy and create a virtual host for an existing CPanel user account, so we can run the following script.

Fourth step: Start Nginx as the default front-end WEB server and create the default configuration file

[Email protected] [/usr]#/opt/ndeploy/scripts/cpanel-ndeploy-setup.sh enablemodifying Apache http and HTTPS port in CPANELHTTPD restarted Successfully. Created symlink From/etc/systemd/system/multi-user.target.wants/nginx.service to/usr/lib/systemd/system/ nginx.service.Created symlink From/etc/systemd/system/multi-user.target.wants/ndeploy_watcher.service to/usr/lib/ systemd/system/ndeploy_watcher.service.created symlink From/etc/systemd/system/multi-user.target.wants/ndeploy_ Backends.service To/usr/lib/systemd/system/ndeploy_backends.service.confgen:: Saheethaconfgen:: SATest

You can see that this script will modify the Apache port from 80 to another port to let Nginx act as a front-end WEB server and create a virtual host profile for an existing CPanel user. Once completed, confirm the status of Apache and Nginx.

Apache Status:

[Email protected] [/var/run/httpd]# systemctl status httpd httpd.service-apache Web serverloaded:loaded (/usr/lib/systemd/system/httpd .

Nginx is running as a front-end server on port 80, and the Apache configuration is changed to listen on HTTP port 9999 and HTTPS Port 4430. Please look at their situation:

[Email protected] [/usr/local/src]# Netstat-plan | grep httpdtcp 0 0 0.0.0.0:4430 0.0.0.0:* LISTEN 17270/httpdtcp 0 0 0.0.0.0:9999 0.0.0.0:* LISTEN 17270/httpdtcp6 0 0::: 44 -:::* LISTEN 17270/httpdtcp6 0 0::: 9999:::* LISTEN 17270/httpd

[Email protected] [/usr/local/src]# Netstat-plan | grep nginxtcp 0 0 127.0.0.1:80 0.0.0.0:* LISTEN 17802/nginx:mastertcp 0 0 45.79.183.73:80 0.0.0.0:* LISTEN 17802/nginx:m Aster

The configuration file for a virtual host created for an existing user is "/etc/nginx/sites-enabled". This file path contains the Nginx main configuration file.

[Email protected] [/etc/nginx/sites-enabled]# ll | grep. conf-rw-r--r--1 root root 311 Jan 09:02 saheetha.com.conf-rw-r--r--1 root root 336 Jan 09:02 saheethastest.c Om.conf

example virtual host for a domain name:

server {listen 45.79.183.73:80; #CPIPVSIX: 80;# servernamesserver_name saheetha.com www.saheetha.com;access_log/usr/ Local/apache/domlogs/saheetha.com Main;access_log/usr/local/apache/domlogs/saheetha.com-bytes_log Bytes_log; Include/etc/nginx/sites-enabled/saheetha.com.include;}

We can start the browser to view the Web site to determine the working status of the Web server. After you install, read the Web service information on the server.

[Email protected] [/home]# IP A | Grep-i eth03:eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> MTU Qdisc pfifo_fast State up Qlen 1000inet 45.79.183.73 /24 BRD 45.79.183.255 Scope Global Dynamic Eth0[email protected] [/home]# Nginx-vnginx version:nginx/1.8.0

Nginx will create a virtual host for any account that is newly created in CPanel. With these simple steps, we are able to configure Nginx as a reverse proxy on a CentOS 7/cpanel server.

the advantages of Nginx as a reverse proxy

1. Easy to install and configure.
2. High efficiency and good performance.
3. Prevent Ddos attacks.
4. supports the use of. htaccess as a rewrite rule for PHP.

I hope this article will be of use to you. Thank you for looking at it. I am very pleased to receive your valuable comments and suggestions and to further improve.
