RHEL Apache (Plesk) rebuild
By default, Apache distribution shipped with RHEL is compiled with a hard limit of 300 FDs. A busy server requires a lot more..This is how I increased the FD hard limit based on SW-Soft’s FAQ: http://faq.sw-soft.com/index.php?ToDo=view&questId=172&catId=42
A bit outdated, but that’ll do! 🙂
Add the following line to /etc/sysctl.conf:
fs.file-max = 131072
Run the following shell command:
# sysctl -w fs.file-max=131072
Edit __FD_SETSIZE value in /usr/include/bits/typesizes.h to:
#define __FD_SETSIZE 32768
(before, it is 1024)
Find httpd’s source rpm (try rpmfind or Google) and rebuild the package.
xmlto and pcre-devel are required, install both with up2date.
Other craps will be installed too:
pcre-devel xmlto docbook-dtds docbook-style-xsl passivetex sgml-common tetex xml-common xmltex tetex-fonts tetex-latex
Feel free to remove them once package has been rebuilt.
To rebuild the httpd rpm from the source rpm:
rpmbuild –rebuild sourcerpmfilehere.src.rpm
Once the custom binary rpm is ready, install it with -Uvh –force
Although the rebuild process produces 4 rpm files, I think only the httpd rpm is required.
Restart apache with the following commands:
/usr/local/psa/admin/sbin/websrvmng -a -v (not sure why this is needed)
service httpd restart

PowerDNS with Plesk servers
Having separate secondary NS for Plesk servers will be difficult to manage. To ease the process, I came up with an idea of using PowerDNS’ supermasters feature.
Just shove in the IP of the Plesk server, the name of the secondary NS and the server name to the supermasters table.
During initial touch-up of the Plesk server, make sure while modifying the DNS zone template to use THAT Plesk server as the first NS record. Otherwise it would cause problem with wrong SOA name causing PowerDNS not recognizing AXFR sent by the Plesk server.
Also make sure PowerDNS IP is included in the allowed list of AXFR on Plesk!
Some useful queries for PowerDNS’ SQL:
delete records.* from records, domains where records.domain_id = domains.id and domains.account = ‘SERVERNAME’;
delete from domains where account = ‘SERVERNAME’;

Plesk’s drwebd issue
If drwebd doesn’t want to start, with the following error message:
Plesk authorization failed: HTTP request error [6]
Error: Plesk Software not running.
Make sure localhost is resolving correctly to 127.0.0.1. Check /etc/hosts!

Urchin for Plesk
In order to get Urchin working for Plesk. It should run as the same user as the apache.
http://help.urchin.com/index.cgi?&id=1243
To do this, the template (urchinwebd.conf.template) should be the one that’s modified, NOT THE REAL ONE (urchinwebd.conf).
Lines that need to be modified should look like this:
Before:
User nobody
Group psaserv
After:
User psaadm
Group psaserv

Passive FTP workaround for Plesk’s proftpd
Add the following line:
PassivePorts 49152 65534
to /etc/proftpd.conf
NOT /etc/proftpd.include as that file will be overwritten by Plesk regularly.
No need to restart xinetd (/etc/init.d/xinetd restart) as proftpd is executed only when a connection has been attempted on the port.
Add the following line:
/sbin/iptables -A INPUT -p tcp –dport 49152:65534 -j ACCEPT
to /usr/local/psa/var/modules/firewall/firewall-active.sh
That’s all!
Just need to make sure that the last incoming traffic rule is set to deny all.
