Wordpress wordpress speed, with centmin beta

I use centmin.sh menu option 22 wordpress installer in centmin mod 123.09beta01 for my Wordpress7 site currently use Redis cache at nginx level - see site's blog posts for benchmark stats on 2GB DigitalOcean KVM VPS

i choose to prevent mobile caching due to responsive themes looking different on mobile versus desktop

 

centmin.sh menu option 22 auto installed wordpress takes care of it when you answer yes to the prompt asking if you want to exclude mobile from caching

 

Prompt only in 123.09beta01

 

you can manually add the exclusions if you know how

which usually involve editing your keycdn cache enabler, wordpress super cache or redis cache include files

i.e. where ${vhostname} is replaced with your domain.com

for keycdn cache enabler edit and add to /usr/local/nginx/conf/wpincludes/${vhostname}/wpcacheenabler_${vhostname}.conf the following

Code (Text):

    # exclude mobile devices from redis caching
    if ($cmwpcache_device = mobile) { set $cache_uri 'nullcache'; }

for redis nginx level cache, edit and add to /usr/local/nginx/conf/wpincludes/${vhostname}/rediscache_${vhostname}.conf the following

Code (Text):

# exclude mobile devices from redis caching
if ($redis_device = mobile) { set $skip_cache 1; }

For redis nginx cache, then create a new file at /usr/local/nginx/conf/redisupstream.conf and add the code to it

Code (Text):

map $http_user_agent $redis_device {
    default                                     'desktop';
    ~*(iPad|iPhone|Android|IEMobile|Blackberry) 'mobile';
    "~*Firefox.*Mobile"                         'mobile';
    "~*ipod.*mobile"                            'mobile';
    "~*Opera\ Mini"                             'mobile';
    "~*Opera\ Mobile"                           'mobile';
    "~*Mobile"                                  'mobile';
    "~*Tablet"                                  'mobile';
    "~*Kindle"                                  'mobile';
    "~*Windows\ Phone"                          'mobile';
}

upstream redisbackend {
  zone upstream_redis 64k;
  server 127.0.0.1:6379 weight=1 max_fails=3 fail_timeout=30s;
  #server 127.0.0.1:6380 weight=1 max_fails=3 fail_timeout=30s;
  #server 127.0.0.1:6381 weight=1 max_fails=3 fail_timeout=30s;
  #server 127.0.0.1:6382 weight=1 max_fails=3 fail_timeout=30s;
  #server 127.0.0.1:6383 weight=1 max_fails=3 fail_timeout=30s;
  #server 127.0.0.1:6384 weight=1 max_fails=3 fail_timeout=30s;

  #server 127.0.0.1:6380 backup;
  keepalive 4096;
}

then edit /usr/local/nginx/conf/nginx.conf and add an include file for /usr/local/nginx/conf/redisupstream.conf after the existing /usr/local/nginx/conf/fastcgi_param_https_map.conf include file

Code (Text):

include /usr/local/nginx/conf/fastcgi_param_https_map.conf;
include /usr/local/nginx/conf/redisupstream.conf;

for keycdn cache enabler, create file at /usr/local/nginx/conf/wpcacheenabler_map.conf and add code to it

Code (Text):

map $http_user_agent $cmwpcache_device {
    default                                     'desktop';
    ~*(iPad|iPhone|Android|IEMobile|Blackberry) 'mobile';
    "~*Firefox.*Mobile"                         'mobile';
    "~*ipod.*mobile"                            'mobile';
    "~*Opera\ Mini"                             'mobile';
    "~*Opera\ Mobile"                           'mobile';
    "~*Mobile"                                  'mobile';
    "~*Tablet"                                  'mobile';
    "~*Kindle"                                  'mobile';
    "~*Windows\ Phone"                          'mobile';
}

then edit /usr/local/nginx/conf/nginx.conf and add an include file for /usr/local/nginx/conf/wpcacheenabler_map.conf after the existing /usr/local/nginx/conf/fastcgi_param_https_map.conf include file

Code (Text):

include /usr/local/nginx/conf/fastcgi_param_https_map.conf;
include /usr/local/nginx/conf/wpcacheenabler_map.conf;

then restart nginx and php-fpm

Code (Text):

nprestart

If older wordpress auto installs had different path to include file you need to edit, post your nginx vhost contents here.

When you create a new nginx vhost domain via centmin.sh menu option 2 or menu option 22 or via /usr/bin/nv cli command line, you will create the Nginx vhost files and directories. You will get an outputted the path location where it will create the domain name's vhost conf file named newdomain.com.conf (and newdomain.com.ssl.conf if you selected yes to self signed SSL)

• Nginx vhost conf path will be at /usr/local/nginx/conf/conf.d/newdomain.com.conf
• Nginx HTTP/2 SSL vhost conf path will be at /usr/local/nginx/conf/conf.d/newdomain.com.ssl.conf
• Nginx Self-Signed SSL Certificate Directory at /usr/local/nginx/conf/ssl/newdomain.com
• Vhost public web root will be at /home/nginx/domains/newdomain.com/public
• Vhost log directory will be at /home/nginx/domains/newdomain.com/log

Please post the contents of /usr/local/nginx/conf/conf.d/newdomain.com.conf and if applicable /usr/local/nginx/conf/conf.d/newdomain.com.ssl.conf wrapped in CODE tags (outlined at How to use forum BBCODE code tags)

 

yeah that's why Centmin Mod 123.09beta01 switched centmin.sh to allow KeyCDN Cache Enabler or Redis nginx level caching selections on top of WP Super Cache

also why I highly recommend using Centmin Mod 123.09beta01

You can try manually switching to keycdn cacher enabler Wordpress - WP Cacher Enabler Plugin by KeyCDN folks.

Latest details on what KeyCDN Cache Enabler is Free WordPress Cache Enabler Plugin

 

Choice is let up to end users to decide for themselves as to whether to disable mobile caching
