Applicable to:
- Plesk for Linux
Symptoms
-
A website fails to load with one of the following errors in a web browser:
PLESK_INFO: 502 Bad Gateway
PLESK_INFO: 503 Service Unavailable
-
The following error message is logged in domain's error log (Plesk > Domains > example.com > Logs):
CONFIG_TEXT: (111)Connection refused: AH02454: FCGI: attempt to connect to Unix domain socket /var/www/vhosts/system/inagaming.com/php-fpm.sock (*:80) failed
-
When changing a PHP handler for a domain or creating a new domain, the operation fails with:
PLESK_ERROR: Error: phpinimng failed: invoke-rc.d: initscript plesk-phpXX-fpm, action "status" failed. invoke-rc.d: initscript plesk-phpXX-fpm, action "status" failed. Service plesk-phpXX-fpm is down after attempt to start it
PLESK_ERROR: Error: phpinimng failed: WARNING:main:Removal of configuration file failed: [Errno 2] No such file or directory: '/opt/plesk/php/7.4/etc/php-fpm.d/example.com.conf'
Job for plesk-php74-fpm.service failed because the control process exited with error code. -
When renaming a domain or migrating a subscription, the operation fails with:
PLESK_ERROR: Error: phpinimng failed: configuration test '/opt/plesk/php/x.x/sbin/php-fpm --test' failed with code 78, and message: ERROR: [pool example.org] the prefix '/var/www/vhosts/system/example.org' does not exist or is not a directory ERROR: failed to post process the configuration ERROR: FPM initialization failed
-
The
plesk-phpXX-fpmservice (where XX is a PHP version) is down and cannot be started. The following error message is logged in/var/log/plesk-phpXX-fpm/error.log:CONFIG_TEXT: ERROR: [pool example.org] the prefix '/var/www/vhosts/system/example.org' does not exist or is not a directory
ERROR: failed to post process the configuration
ERROR: FPM initialization failed
Cause
The domain was removed incompletely: example.org (from the error message in PHP-FPM log) does not exist in Plesk, but its PHP configuration file is present on the server:
-
# ls /opt/plesk/php/8.2/etc/php-fpm.d/example.org.conf
/opt/plesk/php/8.2/etc/php-fpm.d/example.org.conf
Resolution
-
Connect to the Plesk server via SSH.
Note: In case of migration, connect to the destination server.
-
Repair web-server configuration:
# plesk repair web -y
Check if the domain web content files and configuration file exist on the server, if the domain is registered in Plesk database:
# ls -al /var/www/vhosts/system/example.com
# httpd -D DUMP_VHOSTS | grep example.com
# plesk db "select * from domains where name like '%example%'"
-
If domain's website files do not exist on the server and the domain is not registered in Plesk database:
-
Remove its configuration file:
# rm /opt/plesk/php/X.X/etc/php-fpm.d/example.com.conf
-
Restart the affected PHP service (where XX is the affected PHP version):
# service plesk-phpXX-fpm restart
-
-
If domain's website files exist on the server and the domain exists in Plesk:
-
Re-create
/var/www/vhosts/system/example.comconfiguration directory:# mkdir -p /var/www/vhosts/system/subdomain.example.com
-
Restart the
plesk-phpXX-fpmservice (where XX is the affected PHP version):# service plesk-phpXX-fpm restart
- Reconfigure domain:
# plesk repair web example.com
-
Removing redundant files of all affected domains
-
Find all domains with PHP support disabled:
# plesk db -Ne "select d.name from hosting h join domains d on h.dom_id=d.id where php='false'" > /tmp/list
-
Find redundant PHP-FPM files that exist for domains without PHP:
# while read i; do find /opt/plesk/php/ /etc/php-fpm.d/ -name $i*; done < /tmp/list
-
Remove all files found as a result of executing the command on step 3.
