Error in Plesk: New configuration files for the Apache web server were not created due to the errors in configuration templates

Symptoms:

• Nginx is running fine and its configuration is successful:

  # nginx -t
  nginx: the configuration file /etc/nginx/nginx.conf syntax is ok
  nginx: configuration file /etc/nginx/nginx.conf test is successful

• A similar to the below error message appears on the Home page in Plesk

  PLESK_ERROR: New configuration files for the Apache web server were not created due to the errors in configuration templates: nginx: [warn] conflicting server name "example.com" on 203.0.113.2:80, ignored nginx: [emerg] open() "/var/www/vhosts/system/example.com/logs/proxy_access_log" failed (24: Too many open files) nginx: configuration file /etc/nginx/nginx.conf test failed

• The following command returns a non-empty result:

  # plesk db "select description from Configurations where status <> 'ok'\G"

Cause

The issue with web-server configuration has been previously fixed, but the Plesk database still contains old error messages.

Resolution

1. Connect to the server via SSH.

2. Create folder for temporary used files:

   # mkdir -p /tmp/plesksupport

3. Create file with other affected domains:

   # MYSQL_PWD=`cat /etc/psa/.psa.shadow` mysql -uadmin psa -Ne"select name from domains where id in (select objectId from Configurations where status<>'ok')" > /tmp/plesksupport/domainlist.txt

4. Reconfigure other affected domains:

   # cat /tmp/plesksupport/domainlist.txt | while read domain; do /usr/local/psa/admin/bin/httpdmng --reconfigure-domain $domain; echo "$domain - success"; done
   # /usr/local/psa/admin/bin/httpdmng --reconfigure-server
