Redis Nginx Redis + Wordpress

Regarded Nginx Level Redis Cache, in instructions said that

Create the include file /usr/local/nginx/conf/rediscache_newdomain.com.conf and add to it the following code

Code:

set $skip_cache 0;

    # POST requests and urls with a query string should always go to PHP
    if ($request_method = POST) {
        set $skip_cache 1;
    }
    if ($query_string != "") {
        set $skip_cache 1;
    }

    # Don't cache uris containing the following segments
    if ($request_uri ~* "/wp-admin/|/xmlrpc.php|wp-.*.php|/feed/|index.php|sitemap(_index)?.xml") {
        set $skip_cache 1;
    }

    # Don't use the cache for logged in users or recent commenters
    if ($http_cookie ~* "comment_author|wordpress_[a-f0-9]+|wp-postpass|wordpress_no_cache|wordpress_logged_in") {
        set $skip_cache 1;
    }

    location /redis-fetch {
        internal  ;
        set  $redis_key $args;
        redis_pass  127.0.0.1:6379;
    }

    location /redis-store {
        internal  ;
        set_unescape_uri $key $arg_key ;
        redis2_query set $key $echo_request_body;
        redis2_query expire $key 6h;
        redis2_pass  127.0.0.1:6379;
    }

Click to expand...

But I allready have that file on server which is automatically creted when I use option 22 to install wordpress via Centminmod. I selected the option to use Cache Enabler instead of super cache. Content of that default file is little different:

Code:

set $skip_cache 0;

# POST requests and urls with a query string should always go to PHP
if ($request_method = POST) {
  set $skip_cache 1;
}

if ($query_string != "") {
  set $skip_cache 1;
}

# Don't cache uris containing the following segments
if ($request_uri ~* "/wp-admin/|/xmlrpc.php|wp-.*.php|/feed/|index.php|sitemap(_index)?.xml") {
  set $skip_cache 1;
}

# Don't use the cache for logged in users or recent commenters
if ($http_cookie ~* "comment_author|wordpress_[a-f0-9]+|wp-postpass|wordpress_no_cache|wordpress_logged_in") {
  set $skip_cache 1;
}

location /redis-fetch {
  internal  ;
  set  $redis_key $args;
  redis_pass  redisbackend;
  redis_connect_timeout 60000;
  redis_read_timeout 60000;
  redis_send_timeout 60000;
}

location /redis-store {
  internal  ;
  set_unescape_uri $key $arg_key ;
  redis2_query set $key $echo_request_body;
  redis2_query expire $key 6h;
  redis2_pass  redisbackend;
  redis2_connect_timeout 60s;
  redis2_read_timeout 60s;
  redis2_send_timeout 60s;
}

Should I just use default file or I need to merge something in it from your sggested file @eva2000 ?

Also, all other steps in instruction are good to continue (just replace Cache Enabler instances instead of super cache for comment out).

just use the auto generated one that's what it's for

Maybe is not connected with this, but maybe it is.
wordpres iss installed on subdomain, and yesterday I switch wordpress to Nginx Level Redis Cache.

Today, all day I have problem with my forum which is also on Redis cache, and all day more or less pages on forum not loaded with all css, or javascript, or error 500. Something similiar what I have seen here on this board from time to time.

I went to wordpress ACP and purge all cache from there, and my forum is loading OK right now.

Could this error be related to redis cache because both forum and wordpress is on same nginx redis cache, or something else is behind all that?

Some logs, but nothing new in there, as I read every day. Maybe this first one (www-php.error.log) is with new stuff, all others are similiar from day to day:

different document roots

doing line breaks so you can see

Code:

open_basedir restriction in effect. 
File(/home/nginx/domains/pijanitvor.com/public/library/Zend/Cache/Exception.php) 
is not within the allowed path(s): 
(/home/nginx/domains/shop.pijanitvor.com/public/:/usr/local/lib/php/:/tmp/)

open_basedir restricts each vhost to their respective doc roots which for your vhost is /home/nginx/domains/shop.pijanitvor.com/public/ but your xenforo install is trying to access a different document root at /home/nginx/domains/pijanitvor.com/public

you may have setup a custom php.conf include file somewhere in a location match ? what does these commands output for you ?
find all files which have the open_basedir setting in it

Code:

grep -Rno 'PHP_ADMIN_VALUE open_basedir' /usr/local/nginx/conf/*

i.e.

Code:

grep -Rno 'PHP_ADMIN_VALUE open_basedir' /usr/local/nginx/conf/*
/usr/local/nginx/conf/php-pool2.conf:9:PHP_ADMIN_VALUE open_basedir
/usr/local/nginx/conf/php-pool3.conf:9:PHP_ADMIN_VALUE open_basedir
/usr/local/nginx/conf/php-pool4.conf:9:PHP_ADMIN_VALUE open_basedir
/usr/local/nginx/conf/php-pool5.conf:9:PHP_ADMIN_VALUE open_basedir
/usr/local/nginx/conf/php.conf:9:PHP_ADMIN_VALUE open_basedir
/usr/local/nginx/conf/phpalt.conf:11:PHP_ADMIN_VALUE open_basedir
/usr/local/nginx/conf/phpssl.conf:9:PHP_ADMIN_VALUE open_basedir

then find all the files with those php include files (which have open_basedir setting) contained within them

Code:

for f in $(grep -R 'PHP_ADMIN_VALUE open_basedir' /usr/local/nginx/conf/* | awk -F ":" '{print $1}' | uniq); do grep -R "$f" /usr/local/nginx/conf/*; done

i.e.

Code:

for f in $(grep -R 'PHP_ADMIN_VALUE open_basedir' /usr/local/nginx/conf/* | awk -F ":" '{print $1}' | uniq); do grep -R "$f" /usr/local/nginx/conf/*; done

/usr/local/nginx/conf/php-rediscache.conf has a openbase_dir restriction too so might want to comment it out there too although no idea why your xenforo install is trying reach into your wordpress install on shop. subdomain

eva2000 · Jan 19, 2016

also you can check all vhost files and see all references to document root settings to see if any are out of place

for pijanitvor.com
Code:
grep -Rn 'root.*\/home\/nginx\/domains\/pijanitvor.com' /usr/local/nginx/conf/conf.d/*
for shop.pijanitvor.com
Code:
grep -Rn 'root.*\/home\/nginx\/domains\/shop.pijanitvor.com' /usr/local/nginx/conf/conf.d/*

Should I reverse changes for redis cache for wordpress and setup again old cache - Cache Enabler?

eva2000 · Jan 19, 2016

looks okay there.. you should just let the change you made to https://community.centminmod.com/posts/24440/ run a few hours to see if the error pops up again

and for good measure restart both nginx and php-fpm as the openbase_dir while is a php setting, it's implemented at nginx level
Code:
nprestart
and maybe flush redis cache and restart redis
Code:
redis-cli flushall
service redis restart

Today, all day I have problem with my forum which is also on Redis cache, and all day more or less pages on forum not loaded with all css, or javascript, or error 500. Something similiar what I have seen here on this board from time to time.

I went to wordpress ACP and purge all cache from there, and my forum is loading OK right now.

Could this error be related to redis cache because both forum and wordpress is on same nginx redis cache, or something else is behind all that?

Any thoughts about this? Is it Redis the one that could be clash

eva2000 · Jan 19, 2016

see previous post about flushing and restarting redis too https://community.centminmod.com/posts/24443/

it shouldn't clash as they'd have unique redis keys in redis database 0 right @Xon ?

looks good for redis just you need to disable transparent huge pages but that doesn't cause your problems just another unrelated matter

when you run php upgrade and have zend opcache installed/select yes it should auto detect when redis is installed and auto disable transparent huge pages see code at centminmod/zendopcache_tweaks.inc at 123.09beta01 · centminmod/centminmod · GitHub unless you installed redis after php upgrade which then won't detect such

you can use a standalone tools/hptweaks.sh in centmin mod 123.09beta01 to manually disable such or just manually via command
Code:
echo never > /sys/kernel/mm/transparent_hugepage/enabled
then ensure after reboot it's disabled too
Code:
echo "echo never > /sys/kernel/mm/transparent_hugepage/enabled" >> /etc/rc.local

it shouldn't clash as they'd have unique redis keys in redis database 0 right @Xon ?

Correct. XF actually prefixes all it's IDs before they hit the caching layer too.

redis nginx level works fine with wp super cache or keycdn cache enabler plugins

In here - https://community.centminmod.com/posts/18828/ there is a section titled "Switch from WP Super Cache to Nginx Level Redis Cache"

Why is it that you had to switch between the two if it works fine together?
