Plesk, really useful commands

Ok, I’ve made a text file of all those tricky commands I use on plesk FC2. Many of them have saved my bacon, or just been really useful

cat /var/log/messages | tail -200
What has the server been up to? This message shows the last 200 lines of the servers log, it’s good to track down all sorts like dns errors and ftp errors.

tail /var/log/messages -f -n 14000 | grep ‘Jun 1′
Show server messages from a certain date ( June 1st )

du -sk*
Disk usage, there’s all sorts of variants, but this one’s me fav
chown -R user:group *
Changes the owner of files recursively

chmod -R 755 *
changes the permissions of files recursively

mysql -uadmin -p`cat /etc/psa/.psa.shadow` psa -e’delete from PMM’
Fixes updater never stopping error

mysqlcheck -o -u admin -p`cat /etc/psa/.psa.shadow` –all-databases
Optimizes all tables

Here’s one for all those people having problems with character sets:
When using MySQL’s UTF-8 character set, besides setting the database character set to UTF-8, you must remember to send SET NAMES ‘utf8′ to MySQL prior to querying or inserting. Forgetting to do will surely cost you a substantial amount of hair, sleep, and sanity.

Quickly Install Zend 3.0 and then fix php
cd /usr/local/src
wget http://www.eth0.us/files/ZendOptimizer-3.0.1-linux-glibc21-i386.tar.gz
tar -zxf ZendOptimizer-3.0.1-linux-glibc21-i386.tar.gz
cd ZendOptimizer-3.0.1-linux-glibc21-i386
./install

Now just hit enter a few times until it is done…
This guy is on the right track, what you need to do is cut out the [Zend] block of text from your php.ini file:

[Zend]
zend_extension_manager.optimizer=/usr/local/Zend/lib/Optimizer-3.0.1
zend_extension_manager.optimizer_ts=/usr/local/Zend/lib/Optimizer_TS-3.0.1
zend_optimizer.version=3.0.1
zend_extension=/usr/local/Zend/lib/ZendExtensionManager.so
zend_extension_ts=/usr/local/Zend/lib/ZendExtensionManager_TS.so

(usr/local/Zend/etc/php.ini as default) and paste it into a file in the /etc/php.d/ directory, you can name the file anything, i called mine zend.ini.

The problem arises because (like this guy said) ionCube will not allow php to run if theres a similar module loaded before it:

PHP Fatal error: [ionCube Loader] The Loader must appear as the first entry in the php.ini file in Unknown on line 0

and since ionCube is an include (in the php.d directory), and the zend code is pasted directly in the php.ini file, the zend code gets executed first. So as long as you move the zend code after the ionCube code, everything should work just fine… just remember, file includes with regards to php and apache are alphabetical, so if you name your file aaazend.ini it will still error out because it comes before ionCube-loader.ini (or whatever your ionCube file is called).
