How do I enable Piped Logs for Apache Web Server.

  • Plesk 8.2 for Linux/Unix
  • Plesk 8.3 for Linux/Unix
  • Plesk 8.4 for Linux/Unix

Symptoms

If you are going to host more than 300 Web sites on the server, Apache may fail to work because of problem with file descriptors limit. Apache by default can handle only 1024 file descriptors. Every Virtual Host requires 2 or 4 (if HTTPS is enabled) log files, so with this scheme only about 300 domains can be hosted without Apache recompilation, see 260.

Resolution

Piped Logs feature that was implemented in Plesk 8.2 allows to host safely on the default Apache web server build up to 900 domains. If you have more that 900 domains, you still have to recompile Apache and some other system packages as described in article 260. To enable Piped Logs the following steps have to be done:

   1. Log in to the server shell.
   2. Issue the command:
# mysql -uadmin -p`cat /etc/psa/.psa.shadow` psa -e "replace into misc (param,val) values ('apache_pipelog', 'true');"

   3. Rebuild Apache configuration:
# $PRODUCT_ROOT_D/admin/sbin/websrvmng -v -a
