What is eAccelerator?

[Daniel15]

I did it on 1 server which is working... just on the end. but I am installing some new servers now and there is a line already with zend, just do a search.

PHP 5.0.4 is very old, and has security vulnerabilities. I suggest you update as soon as possible!

When I type php -v I get:

PHP Warning:  PHP Startup: Unable to load dynamic library '/usr/lib/php/modules/ea/eaccelerator-0.9.5-beta1/modules/eaccelerator.so' - /usr/lib/php/modules/ea/eaccelerator-0.9.5-beta1/modules/eaccelerator.so: cannot open shared object file: No such file or directory in Unknown on line 0

For anyone that's wondering about this, after you run make install, it should tell you the path it's installed into. On the systems I admin (CentOS and RHEL4, both using PHP 5.2.1), this is at /usr/local/lib/php/extensions/no-debug-non-zts-20060613/, so the extension line should look like:
extension=/usr/local/lib/php/extensions/no-debug-non-zts-20060613/eaccelerator.so .

On my personal Debian Etch system, it's at /usr/lib/php5/20060613+lfs instead.

EDIT: Note that I now use XCache rather than eAccelerator. I've found XCache to be much faster than eAccelerator . If you like, I can post a how to on this (although it's really quite easy, just follow their instructions)

thanks for noticing me, just a brand new server with fedora core 4, all software needs an update!

Now I have these errors in my error log under Log files root directory/httpd

...
EACCELERATOR hit: "/var/www/html/index.php"
EACCELERATOR hit: "/var/www/html/index.php"
EACCELERATOR hit: "/var/www/html/phpinfo.php"

Is this normal?

They're not errors, that's information produced by eAccelerator when debug mode is turned on (a "hit" is when something is loaded from the cache, whereas a "miss" is when something isn't loaded from cache). To disable these messages, make sure debug mode is turned off in php.ini:

Thanks Daniel15,
In smf settings, under serversettings -> Cache. SMF says it recognize eAccelerator, but do I have to do something (Now the caching level is set to "No cacheing") or does SMF use eAccelerator as default?
Do I have to activate local storage of cookies?

Cordially,
Johan

You need to compile eAccelerator with a certain flag, I believe it's --enable-eaccelerator-content-caching, but I'm not quite sure (I'd need to look it up). Try running ./configure --help, and see if it tells you anything.

[Joshua Dickerson]

Yeah, it needs a flag to run right. I think they should just enable it by default and have a flag to disable it.

[Ben_S]

The required flag is in the first post of this topic. Stupid eAccelerator.

[chep]

great instructions.

[Daniel15]

great instructions.

Glad we could help you

My host just installed eAccelerator and here is what they gave me:

Now my question was, that when I check the Caching tab in the Admin panel it still says that SMF cannot find a compatible accelerator.  I went ahead and set it to level 1 anyways, but I wanted to make sure that wasnt a problem and if there was a way i could check to make sure it was working proper?  Thanks!

[chep]

You should check phpinfo and in there will be a section under eaccelerator. Here's what mine says for example.

As you see there are 582 cached scripts. I know it is working...

[chep]

There was some talk about Zend Optimizer and eaccelerator not working well together unless they were listed in a specific order inside php.ini

Don't ask me what order would be correct but I found other documents on the web last night which also backed the claim to that... which I believe was mentioned earlier in this topic.

I don't know if you have to restart something on your apache server to recognize the eaccelerator or not in your case. I don't remember doing in anything special last night for that.

I can't really offer any more information than that. I do not have the Zend Optimizer on my server... Eaccelerator certainly has helped out a lot it seems..

[littleone]

where do i find php.ini?

[chep]

Look at the results from phpinfo

Configuration File (php.ini) Path  /etc/php.ini 

[littleone]

ok you were right.  I needed to restart Apache.  Now its singing like a bird.  Looks just like what you posted from your site.  Greatly Appreciate your help
