How to use cPanel to configure Nginx reverse proxy in CentOS 7
cPanel is the most powerful, easiest to use, and most popular virtual host control system in the world. Many foreign hosts use this control panel.
First, we need to install the EPEL library to start this process
Step one: Install the EPEL library
root@server1 [/usr]# yum -y install epel-releaseLoaded plugins: fastestmirror, tsflags, universal-hooks Loading mirror speeds from cached hostfile * EA4: 66.23.237.210 * base: mirrors.linode.com * extras: mirrors.linode.com * updates: mirrors.linode.com Resolving Dependencies --> Running transaction check ---> Package epel-release.noarch 0:7-5 will be installed --> Finished Dependency Resolution Dependencies Resolved ======================================================================================== Package Arch Version Repository Size ======================================================================================== Installing: epel-release noarch 7-5 extras 14 k
Step 2: Install nDeploy's CentOS RPM library
You can install nDeploy's CentOS RPM library to install the nDeploy Web class software and Nginx plug-in we need
root@server1 [/usr]# yum -y install http://rpm.piserve.com/nDeploy-release-centos-1.0-1.noarch.rpmLoaded plugins: fastestmirror, tsflags, universal-hooks nDeploy-release-centos-1.0-1.noarch.rpm | 1.7 kB 00:00:00 Examining /var/tmp/yum-root-ei5tWJ/nDeploy-release-centos-1.0-1.noarch.rpm: nDeploy-release-centos-1.0-1.noarch Marking /var/tmp/yum-root-ei5tWJ/nDeploy-release-centos-1.0-1.noarch.rpm to be installed Resolving Dependencies --> Running transaction check ---> Package nDeploy-release-centos.noarch 0:1.0-1 will be installed --> Finished Dependency Resolution Dependencies Resolved ======================================================================================== Package Arch Version Repository Size ======================================================================================== Installing: nDeploy-release-centos noarch 1.0-1 /nDeploy-release-centos-1.0-1.noarch 110
Third Step: Install nDeploy and Nginx nDeploy plug-in
root@server1 [/usr]# yum --enablerepo=ndeploy install nginx-nDeploy nDeployLoaded plugins: fastestmirror, tsflags, universal-hooks epel/x86_64/metalink | 9.9 kB 00:00:00 epel | 4.3 kB 00:00:00 ndeploy | 2.9 kB 00:00:00 (1/4): ndeploy/7/x86_64/primary_db | 14 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 00:00:02 Dependencies Resolved ======================================================================================== Package Arch Version Repository Size ======================================================================================== Installing: nDeploy noarch 2.0-11.el7 ndeploy 80 k nginx-nDeploy x86_64 1.8.0-34.el7 ndeploy 36 M Installing for dependencies: PyYAML x86_64 3.10-11.el7 base 153 k libevent x86_64 2.0.21-4.el7 base 214 k memcached x86_64 1.4.15-9.el7 base 84 k python-inotify noarch 0.9.4-4.el7 base 49 k python-lxml x86_64 3.2.1-4.el7 base 758 k Transaction Summary ======================================================================================== Install 2 Packages (+5 Dependent packages)
We installed the Nginx plug-in on our server and completed the installation according to the above steps. Now we can configure Nginx as a reverse proxy and create a virtual host for the existing cPanel user account, for which we can run the following script.
Step 4: Start Nginx as the default front-end web server and create the default configuration file
root@server1 [/usr]# /opt/nDeploy/scripts/cpanel-nDeploy-setup.sh enableModifying apache http and https port in cpanel httpd 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:: saheetha ConfGen:: satest
You can see that this script will modify the Apache port from 80 to another port to use Nginx as a front-end web server and create a virtual host profile for existing cPanel users. Once completed, confirm the status of Apache and Nginx.
Apache status:
root@server1 [/var/run/httpd]# systemctl status httpd● httpd.service - Apache Web Server Loaded: loaded (/usr/lib/systemd/system/httpd.service; enabled; vendor preset: disabled) Active: active (running) since Mon 2016-01-18 06:34:23 UTC; 12s ago Process: 25606 ExecStart=/usr/sbin/apachectl start (code=exited, status=0/SUCCESS) Main PID: 24760 (httpd) CGroup: /system.slice/httpd.service ‣ 24760 /usr/local/apache/bin/httpd -k start Jan 18 06:34:23 server1.centos7-test.com systemd[1]: Starting Apache Web Server...

Nginx status:

Nginx runs as a front-end server on port 80, and the Apache configuration is Change to listen on http port 9999 and https port 4430. Please take a look at their situation:
root@server1 [/usr/local/src]# netstat -plan | grep httpdtcp 0 0 0.0.0.0:4430 0.0.0.0:* LISTEN 17270/httpd tcp 0 0 0.0.0.0:9999 0.0.0.0:* LISTEN 17270/httpd tcp6 0 0 :::4430 :::* LISTEN 17270/httpd tcp6 0 0 :::9999 :::* LISTEN 17270/httpd
root@server1 [/usr/local/src]# netstat -plan | grep nginxtcp 0 0 127.0.0.1:80 0.0.0.0:* LISTEN 17802/nginx: master tcp 0 0 45.79.183.73:80 0.0.0.0:* LISTEN 17802/nginx: master
The configuration file of the virtual host created for an existing user is in "/etc/nginx/sites-enabled". This file path contains the main Nginx configuration files.
root@server1 [/etc/nginx/sites-enabled]# ll | grep .conf-rw-r--r-- 1 root root 311 Jan 17 09:02 saheetha.com.conf-rw-r--r-- 1 root root 336 Jan 17 09:02 saheethastest.com.conf
Example virtual host of 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 website to determine the working status of the web server. After installation, read the web service information on the server.
root@server1 [/home]# ip a | grep -i eth03: eth0: mtu 1500 qdisc pfifo_fast state UP qlen 1000 inet 45.79.183.73/24 brd 45.79.183.255 scope global dynamic eth0 root@server1 [/home]# nginx -vnginx version: nginx/1.8.0
Rewrite this sentence to get: For all newly created accounts in cPanel, Nginx will create virtual hosts for them. With these simple steps, we can configure Nginx as a reverse proxy on a CentOS 7 / cPanel server.
Advantages of Nginx as a reverse proxy
Easy to install and configure.
High efficiency and good performance.
Prevent Ddos attacks.
Support using .htaccess as a rewrite rule for PHP.
The above is the detailed content of How to use cPanel to configure Nginx reverse proxy in CentOS 7. For more information, please follow other related articles on the PHP Chinese website!
