If you see following error while backing up databases through phpmyadmin (this happens with large database)
————–
can’t find the file at https://xx.xx.xx.xx:8443/domains/databases/phpMyAdmin/export.php.
————–
Solution :

You can try to increase the value memory_limit in /usr/local/psa/admin/conf/php.ini to higher value and restart
Plesk CP after that.

# cat /usr/local/psa/admin/conf/php.ini | grep memory_limit
memory_limit = 128M

Set it to 512M for example and restart PSA service.

Checking your disk shows that you have plenty of space. The problem is that apache didn’t shut down properly, and it’s left myriads of semaphore-arrays left, owned by my apache-user. Run:-

# ipcs -s | grep nobody

Removing these semaphores immediately should solve the problem and allow apache to start.

# ipcs -s | grep nobody | perl -e ‘while (<STDIN>) { @a=split(/\s+/); print `ipcrm sem $a[1]`}’

If awstats are not working after Plesk upgrade to v8.6 then download updated modules SiteAppStatistics.dll, statistics.exe and copy it to %plesk_bin%. Also make sure to backup old modules before copying.

Next update the stats by running the command -

“%plesk_bin%\statistics.exe” –all

If you see following error message in exim maillogs

==============
2009-08-05 15:30:06 1MYhUc-0007Bz-LU == USER@domain.com R=lookuphost defer (-1): host lookup did not complete
==============

Solution : This is likely because your resolving nameservers are no longer responding to DNS queries. To fix this issue, you can manually edit the /etc/resolv.conf file.

To configure exim to send mail using a different  IP other than the main shared IP.

vi /etc/exim.conf

Search for the following lines in /etc/exim.conf

remote_smtp:
driver = smtp

add the following line ,

interface = IPhere

and restart exim.

This would be helpful when your Main IP is blocked by RBL/CRL/AOL.

How to enable Innodb as default storage engine ?

Solution :

Just edit your /etc/my.cnf file and look for this line:

skip-innodb

If such an entry exists, remove or comment out the entry

#skip-innodb

Next make the storage_engine variable to Innodb by adding following under [mysqld] section.

default-storage_engine = InnoDB
save the file, and restart mysql:

Restart mysql service

This error message can be caused by an improper shut down, the apache processes are still hanging around and apachectl restart won’t work.

Solution

just kill off the hanging processes:
# fuser 80/tcp
80/tcp: 3010 3702 4088 16754
# kill -n 9 3010
# kill -n 9 3702
# kill -n 9 4088
# kill -n 9 16754
# apachectl start

or if there’s loads of processes use
# for i in $(fuser 80/tcp);do kill -n 9 $i;done
to kill them all off
