Web Hosting Talk : Web Hosting Main Forums : Hosting Security and Technology : Hosting Security and Technology Tutorials : eAccelerator Install - method should work for most PHP versions...

[layer0]

Downloadable version: http://noc.medialayer.com/ea.txt
Just wget it and run "sh ea.txt".

edit: see link for updated version(s).

I have ran this on quite a few servers and it works perfectly. Particularly with PHP 4.4.2 and the latest version of Zend Optimizer.

The /scripts/restartsrv_httpd is only available in cPanel, you can replace it:

service httpd stop; service httpd startssl

This should work flawlessly on PHP 5 as well - it's the 0.9.4 version.

HTH,

edit - just fixed some of the wordwrap issues, let me know if you have any problems.

I would like to make a statement about putting the cache directory in /..

Some dedicated providers create a very small / and put everything else in /usr /var and /home... Which could cause / to get full rapidly.. I would look at your partition setup first and then determine where to place it. I like to place it in /home since /home is usually the largest partition.

Yes, that can easily be modified, I might add some variables to the script for easy modification of that...

A lot of other how-tos state that they recommend to place the cache in /tmp - which IMHO is even worse.

- Edit: updated file, should be a lot better now.

Anyone know why it won't work on 4.4.2 for me?

I get httpd configtest = syntax ok

I have shm size in /etc/sysctl.conf set to
kernel.shmmax = 2147483648

apache error shows:

eaccelerator.shm_ttl="0"
eaccelerator.shm_prune_period="0"
eaccelerator.shm_only="0"
eaccelerator.compress="1"
eaccelerator.compress_level="9"

Now this works just fine on 4.4.1 with same config as above but not 4.4.2.

What could be the problem?

If you uninstall eA and use my installer you will not have this problem.

Thanks,

Hello,

Just as an update..if you get

"PHP Warning: Unknown(): Unable to load dynamic library './/usr/local/lib/php/extensions/eaccelerator.so' - .//usr/local/lib/php/extensions/eaccelerator.so: cannot open shared object file: No such file or directory in Unknown on line 0"

in your error_log then you can simply do these changes:

nano -w /usr/local/lib/php.ini

Search for (with CTRL+W) extension_dir

Set the value to "usr/local/lib/php/extensions"

Now search for eaccelerator.so

replace "/usr/local/lib/php/extensions/eaccelerator.so" with just "eaccelerator.so"

exit out

service httpd restart


I have tested that on cPanel and it works fine.

However, if you are running Plesk it can get a bit tricky (you should have disabled IonCube from the beginning actually as well).

Soon I will have a Plesk eAccelerator installer available.

HTH,

[azn_romeo_4u]

how do you know that it's installed? I followed the steps and did sh ea.txt and it just ran a bunch of processes....btw i'm a total noob.

Awesome setup though!

First insure that Apache can be restarted properly.

service httpd restart

then run

php -v

If you see "eaccelerator" there then yes, it has been installed.

I will soon be updating this script to be more interactive and intuitive for newbies.

HTH,

Looks good, but I do not suggest running a beta version. You should run 0.9.4 until 0.9.5 is fully stable.

PHP 5.1.4 work fine with eAccelerator v0.9.5-beta2

[firestarter]

How do I uninstall eAccelerator ?

[firestarter]

I got the information to deactivate eAccelerator. Just need to # out the zend_extension with the eAccelerator line and restart the httpd.
