Question:
Unable to access Plesk: fork/exec /usr/local/psa/admin/bin/php: exec format error
Symptoms

• Plesk is inaccessible with the following error:

ERR_CONNECTION_TIMED_OUT


• Both sw-engine and sw-cp-server services are masked:

#systemctl list-unit-files --type=service | grep sw
sw-cp-server.service masked
sw-engine.service masked

• Plesk commands fail:

#plesk login
fork/exec /usr/local/psa/admin/bin/php: exec format error

• Plesk update fails with the following error:

/usr/local/psa/bin/extension: line 2: ?php: No such file or directory
/usr/local/psa/bin/extension: line 3: syntax error near unexpected token "The file {$_SERVER['SCRIPT_FILENAME']} is part of Plesk distribution. It cannot be run outside of Plesk environment.\n"' /usr/local/psa/bin/extension: line 3: die("The file {$_SERVER['SCRIPT_FILENAME']} is part of Plesk distribution. It cannot be run outside of Plesk environment.\n");'

• The following command shows many Plesk files with 0B in size:

#find /usr/local/psa -type f -size 0 | grep -v modules | grep -v search | grep -v PMM
usr/local/psa/admin/bin/plesk_agent_manager
/usr/local/psa/admin/htdocs/domains/databases/phpMyAdmin/vendor/pragmarx/google2fa/tests/.gitkeep
/usr/local/psa/admin/htdocs/spaw/empty/empty.html
/usr/local/psa/admin/sbin/mchk
/usr/local/psa/admin/sbin/deployer
/usr/local/psa/admin/sbin/backup_encrypt
/usr/local/psa/admin/sbin/backup-archiver

/usr/local/psa/admin/sbin/pmmcli
/usr/local/psa/admin/sbin/pmmcli_daemon

...
Cause
Corrupted Plesk files.

Resolution
1.Connect to the server via SSH;
2.Find the owner of the files with 0B in size:
#find /usr/local/psa -type f -size 0 -exec rpm -qf {} \; | grep -v search | grep -v PMM | grep -v 'not owned' | uniq
plesk-core-18.0-2.centos.7+p18.0.25.2+t200325.1928.x86_64
plesk-service-node-utilities-18.0-2.centos.7+p18.0.25.2+t200325.1928.x86_64
3.Remove them with the following command:
#rpm -e --nodeps --justdb plesk-core
# rpm -e --nodeps --justdb plesk-service-node
4.Run Plesk Installer to reinstall them back:
#plesk installer
5.Restart the psa service:
#systemctl psa restart
