Autoptimize Wordpress Plugin

How To Install WordPress On Centmin Mod LEMP Stack Guide

Last Updated

This WordPress site was created using Centmin Mod’s centmin.sh menu option 22 automatic WordPress installer routine and hosted on a Upcloud.com KVM VPS server running Centmin Mod Nginx, PHP-FPM, MariaDB MySQL on CentOS 7 64bit server paired with Cloudflare free plan. The following guide illustrates how to use the latest Centmin Mod 123.09beta01’s centmin.sh menu option 22 WordPress installer which will install Nginx HTTP/2 HTTPS site with TLS 1.3 support via integrated free Letsencrypt SSL certificates in dual RSA 2048bit + ECDSA 256bit SSL certificate mode and automatically install WordPress and configure the site optimally for both performance and security.

Reading Time: 15 minutes

Step 1.

Ensure you’re using Centmin Mod 123.09beta01 or newer version with integrated free Letsencrypt SSL certificates via addons/acmetool.sh which uses underlying acme.sh client developed by Neil Pang and that you have enabled Letsencrypt SSL support via persistent configuration file /etc/centminmod/custom_config.inc variables below.

  • The first variable LETSENCRYPT_DETECT=’y’ enables regular RSA 2048bit SSL certificates via Letsencrypt.
  • While second variable DUALCERTS=’y’ enables dual RSA 2048bit + ECDSA 256bit SSL certificate mode with a second Letsencrypt SSL certificated being obtained that is ECDSA 256bit based. Dual SSL certificates allow Centmin Mod Nginx to serve better performance based ECDSA 256bit SSL certificates to web browser and clients that support such certificates while falling back to traditional standard RSA 2048bit SSL certificates for older web browser and clients that do not support ECDSA 256bit. In the context of usage with Cloudflare, that means Cloudflare’s connection to Centmin Mod Nginx origin server is optimal as Cloudflare can now communicate with Centmin Mod Nginx origin using faster performing ECDSA 256bit SSL certificates as well as communicate between Cloudflare and Centmin Mod Nginx origin using better performing TLS 1.3 protocol which reduced the connection by 1-RTT – round trip time compared to communicating over older TLS 1.0/1.1/1.2 protocol. That 1-RTT savings can result in as much as 300+ milliseconds faster connection over slow mobile internet connections.
  • When these variables are enabled, centmin.sh menu options 2, 22 and nv command line options to create Nginx vhost sites enable an additional menu options to support obtaining Letsencrypt free SSL certificates. If these variables are not enabled, centmin.sh menu options 2, 22 and nv command line will only provide self-signed SSL certificate for testing purpose.
# enable letsencrypt ssl certificate + dual RSA+ECDSA ssl certs https://centminmod.com/acmetool/
echo "LETSENCRYPT_DETECT='y'" >> /etc/centminmod/custom_config.inc
echo "DUALCERTS='y'" >> /etc/centminmod/custom_config.inc

DUALCERTS=’y’ mode was enabled for this WordPress site via the advanced customisation Centmin Mod installation guide already.

Step 2

Update your intended WordPress site’s domain name DNS A records to point to server’s IP address. You’d need to do that for both non-www and www version of your domain name or intended subdomain as by default addons/acmetool.sh and Letsencrypt SSL certificate integration uses webroot domain validation to verify your domain name before Letsencrypt issues your free SSL certificates. Screenshot is from Cloudflare DNS tab dashboard.

Cloudflare and Letsencrypt webroot authentication

At this stage though, you need to set Cloudflare DNS record as grey cloud not orange cloud proxy as Letsencrypt issuance needs to be able to communicate with your Centmin Mod Nginx origin server for webroot authentication and validation of your domain. If you select Centmin Mod Nginx default HTTPS, then you won’t have a non-HTTPS Nginx vhost origin for Cloudflare Flexible SSL to speak with at this stage, so Letsencrypt webroot authentication will fail unless instead of selecting below option 4 for Letsencrypt Nginx default HTTPS, you select option 3 for Nginx HTTP + HTTPS vhost so both non-HTTPS port 80 and HTTPS port 443 can be communicated to for Letsencrypt webroot authentication. Once Nginx vhost is created you can change your DNS record to orange proxy cloud and change to HTTPS default and Cloudflare Full SSL mode.

Cloudflare DNS

 

Step 3

Run centmin.sh menu option 22 to start the Nginx vhost site generator which will automatically install and configure WordPress as well. A series of question prompts will ask you about how you would like to the Nginx vhost site and WordPress setup to be configured.  The WordPress auto installer utilises WP-CLI command line too to do the heavy lifting for the actual WordPress installation.

Followed by some information notices and prompt for your desired domain name (without www prefix) and whether you want to install self-signed SSL certificates and/or Letsencrypt SSL certificates on Nginx vhost site. Here I choose option 4 for live trusted Letsencrypt SSL certificates with HTTPS default (the non-https to https redirect is automatically configured for you).

-------------------------------------------------------------

Next up is WordPress installer provides users with a choice full page WordPress caching options for better performance. The first 3 are available out of the box as of writing while the 4th option for PHP-FPM fastcgi_cache based full page caching is currently available via a switch for private development and testing. For this blog and testing purposes the choice for option 4 for PHP-FPM fastcgi_cache based full page caching was made. For 99% of usage cases for best performance with least issues and problems, choosing KeyCDN Cache Enabler for static HTML full page caching is the recommended option as it’s a faster and less problematic version of WordPress Super Cache plugin.

Default is to install KeyCDN WP Cache Enabler Plugin as it is more
stable and reliable than WP Super Cache and Redis Cache.
Redis cache may have issues with caching due to long 6hr cache TTL
Fastcgi_cache (PHP-FPM) will have best performance
You can select which caching method to use below:

--------------------------------------------------------
Wordpress Caching 
--------------------------------------------------------
1) KeyCDN Cache Enabler
2) Redis Nginx Level Caching
3) WordPress Super Cache
4) Fastcgi_cache (PHP-FPM)
--------------------------------------------------------
Enter option [ 1 - 4 ] 4

you selected option 4 (Fastcgi_cache PHP-FPM) [wpscache=fastcgicache]

Next up is creating the Pure-ftpd virtual FTP username/password and if you opted for, the HTTP password protection for WordPress login page.

Create FTP username for vhost domain (enter username): FTPUSERNAME
Do you want to auto generate FTP password (recommended) [y/n]: y

FTP username you entered: FTPUSERNAME
FTP password auto generated: FTPPASSWORD

Password: 
Enter it again: 
/usr/local/nginx/conf/htpasswd.sh create /home/nginx/domains/servermanager.guide/htpasswd_wplogin HTTP_USERNAME HTTP_PASSWORD

/home/nginx/domains/servermanager.guide/htpasswd_wplogin contents:
HTTP_USERNAME:$ap******S3gN0bY2.NPw******

Then PHP-FPM fastcgi_cache related Nginx include and configuration files are created and populated. Pay particular attention to the path to /usr/local/nginx/conf/wpfastcgi_cache_map_debug.conf as it allows you to add your ISP IP address to it to reveal and expose some additional hidden Nginx response headers for PHP-FPM fastcgi_cache diagnostics.

touch /usr/local/nginx/conf/wpfastcgi_cache_map_debug.conf
touch /usr/local/nginx/conf/wpfastcgi_cache_map_include_mobile.conf
touch /usr/local/nginx/conf/wpfastcgi_cache_map_include_nocachecookie.conf
touch /usr/local/nginx/conf/wpfastcgi_cache_map_include_nocacheuri.conf

include file /usr/local/nginx/conf/wpfastcgi_cache_path_includes.conf add to nginx.conf

include file /usr/local/nginx/conf/wpfastcgi_cache_map.conf add to nginx.conf

include file /usr/local/nginx/conf/wpcacheenabler_map.conf add to nginx.conf

Contents of where I added my ISP IP address into the include file at /usr/local/nginx/conf/wpfastcgi_cache_map_debug.conf and set it’s to value of 1 which corresponds to Nginx mapped variable called $fastcgi_debug.

cat /usr/local/nginx/conf/wpfastcgi_cache_map_debug.conf
YOUR_ISP_IP_ADDR 1;

The include file is part of another include file at /usr/local/nginx/conf/wpfastcgi_cache_map.conf which maps the visitor’s IP address to $fastcgi_debug variable which decides whether a listed ISP IP address is allowed to see the additional hidden Nginx PHP-FPM fastcgi_cache response headers.

map $remote_addr $fastcgi_debug {
default 0;
include /usr/local/nginx/conf/wpfastcgi_cache_map_debug.conf;
# YOUR_ISP_IP_ADDR 1;
}

With your ISP IP added to enable $fastcgi_debug mapped variable, additional Nginx response headers are available which include, PHP-FPM fastcgi_cache cache status – HIT or BYPASS, as well as x-fpmcache-skip header to give the reason why cache was bypassed and other x-fpmcache headers and request processing time headers.

PHP-FPM fastcgi_cache response headers

Next part is related to SSL certificate setup and configuration. First is that Centmin Mod Nginx generation routines for HTTPS will also setup Cloudflare  Authenticated Origin Pulls TLS client certificates on your Nginx HTTPS site but disable them by default – but the configuration is ready to be enabled just by editing your Nginx vhost configuration file at yourdomain.com.ssl.conf by uncommenting a few lines. This is the part which downloads Cloudflare Authenticated Origin Pulls TLS client certificates.

The Nginx vhost configuration file /usr/local/nginx/conf/conf.d/servermanager.guide.ssl.conf has a commented out (disabled) directive for Cloudflare Authenticated Origin Pulls TLS client certificates ready to be enabled if you choose to enable such feature.

# cloudflare authenticated origin pull cert community.centminmod.com/threads/13847/
#ssl_client_certificate /usr/local/nginx/conf/ssl/cloudflare/servermanager.guide/origin.crt;
#ssl_verify_client on;

To enable, uncomment the 2 directive lines by removing the hash # and then restart Nginx service.

# cloudflare authenticated origin pull cert community.centminmod.com/threads/13847/

ssl_verify_client on;

Then in your Cloudflare Crypto dashboard tab, enable Cloudflare Authenticated Origin Pulls TLS client certificates.

 

Cloudflare Origin Pulls

Next part is regardless of whether you choose to enable self-signed SSL certificates, the Centmin Mod HTTPS routine will generate them automatically as they are also used as fallback in case your Letsencrypt SSL certificate domain verification and issuance fail for whatever reason.

Then the creation of WordPress Nginx site uninstaller and WordPress automatic update cron job scheduler which auto updates WordPress plugins via WP-CLI command line too every 8 hrs. And also creation of autoprotect.sh include file and cronjob schedule which basically checks entire Centmin Mod LEMP stack server’s Nginx vhost site’s public web accessible directories for .htaccess files with DENY ALL directives that exist. Then grabbing their directory path to .htaccess file and auto generating an Nginx equivalent location match and deny all setup to prevent accidental exposure of directories which the web author intended to be private under Apache .htaccess. But Nginx doesn’t support .htaccess so automatic Nginx deny rules are generated to protect your Nginx site.

Step 4

As Cloudflare is used in front of your Centmin Mod Nginx created WordPress site, you will need to ensure visitor’s real IP address is detected by Nginx instead of Cloudflare’s proxy IPs and to ensure Cloudflare’s IP addresses are whitelisted in Centmin Mod CSF Firewall. Centmin Mod 123.09beta01 and newer can do this via tools/csfcf.sh script. Manual steps are also outlined in Getting Started Guide step 5 – link directly to Nginx Cloudflare & Incapsula (reverse proxy HttpRealIpModule).

In your WordPress site’s Nginx vhost config file at /usr/local/nginx/conf/conf.d/servermanager.guide.ssl.conf find the commented out disabled include file, /usr/local/nginx/conf/cloudflare.conf for

# uncomment cloudflare.conf include if using cloudflare for
# server and/or vhost site
#include /usr/local/nginx/conf/cloudflare.conf;

remove the hash in front of the include line to uncomment and enable the include file

# uncomment cloudflare.conf include if using cloudflare for
# server and/or vhost site
include /usr/local/nginx/conf/cloudflare.conf;

Then manually run the tools/csfcf.sh script with auto flag once which will grab latest known Cloudflare IP addresses and whitelist them in CSF Firewall and also populate the include file at /usr/local/nginx/conf/cloudflare.conf with the Nginx settings to allow Nginx to see visitor’s real IP addresses instead of Cloudflare’s proxy IP addresses.

/usr/local/src/centminmod/tools/csfcf.sh auto

Then add to your server’s cronjob the following to run once per day via crontab -e command. You can use crontab -l to view current cronjobs and crontab -e command to invoke nano text editor see guide at HowTo: Add Jobs To cron Under Linux or UNIX?

23 */36 * * * /usr/local/src/centminmod/tools/csfcf.sh auto >/dev/null 2>&1

Example of the auto populated include file /usr/local/nginx/conf/cloudflare.conf contents below:

include /usr/local/nginx/conf/cloudflare_customips.conf;
set_real_ip_from 173.245.48.0/20;
set_real_ip_from 103.21.244.0/22;
set_real_ip_from 103.22.200.0/22;
set_real_ip_from 103.31.4.0/22;
set_real_ip_from 141.101.64.0/18;
set_real_ip_from 108.162.192.0/18;
set_real_ip_from 190.93.240.0/20;
set_real_ip_from 188.114.96.0/20;
set_real_ip_from 197.234.240.0/22;
set_real_ip_from 198.41.128.0/17;
set_real_ip_from 162.158.0.0/15;
set_real_ip_from 104.16.0.0/12;
set_real_ip_from 172.64.0.0/13;
set_real_ip_from 131.0.72.0/22;
#set_real_ip_from 2400:cb00::/32;
#set_real_ip_from 2606:4700::/32;
#set_real_ip_from 2803:f800::/32;
#set_real_ip_from 2405:b500::/32;
#set_real_ip_from 2405:8100::/32;
#set_real_ip_from 2a06:98c0::/29;
#set_real_ip_from 2c0f:f248::/32;
real_ip_header X-Forwarded-For;

Then restart Nginx server

service nginx restart

or via Centmin Mod command shortcut

ngxrestart

Cloudflare and Letsencrypt webroot authentication

Finally at this stage, you can opt to switch and set Cloudflare DNS record from grey cloud to orange cloud proxy as first time Letsencrypt issuance has been validated with your Centmin Mod Nginx origin server for webroot authentication. If you select Centmin Mod Nginx default HTTPS, then select Cloudflare Full SSL mode.
