eaccelerator installation

[surfman]

I am with PHP 4.4.4, when I run

/admin/misc/enable_phpa.sh

choose 3 to enable eaccelerator, nothing happened. when I enter php -v

it shows:

nothing about eaacelerator. any suggestion? I am under Cpanel. thanks.

[surfman]

I also noticed the version under SSH command line is showing

PHP 4.4.2 (cli) (built: May 10 2006 12:17:27)

not PHP 4.4.4

But when I check vbulletin PHP_Info page, it is 4.4.4

any idea? thanks.

[mistwang]

command line php is from the Linux distribution, lsphp bundled in LSWS package is 4.4.4 .
You can use APC instead of eaccelerator which included in the package. you may need to build your own php and eaccelerator.

[surfman]

is there anything shown different after I sucessfully install APC or Eaccelerator? I try choose 1 or 3, nothing changes when I check phpinfo page.

My server has two CPU, there something says APC will not work at more than one CPU when I run

/admin/misc/enable_phpa.sh

is that true?

or, if I re-compile the whole new PHP 4.4.4, how can I replace it with the pre-built PHP under LSWS? thanks.

[surfman]

when I use

/opt/lsws/fcgi-bin/lsphp -i

it will show

Obviously eaccelerator is enabled. but it seems does not work. when I check

phpinfo.php

at broswer, I will see nothing about eaccelerator although showing php 4.4.4 that is pre-built php in litespeed.

anyway for eaccelerator to work without re-compile PHP? thanks.

[mistwang]

Earlier version of APC has issue with SMP server, should have been fixed in current release.

It is strange that it works on command line, but not from within web server.
Please double check the phpinfo.php output, see if php configuration file /opt/lsws/conf/php.ini has been used. it might be a permission issue with the php.ini.

[surfman]

may I know the permission for /opt/lsws/conf/php.ini ? 644 or 755?

[mistwang]

644 is fine. the problem probably is the permission of /opt/lsws/conf directory, for security reason, it is set to 0700, it not recommended to set it to 0755.
When lsphp started in suexec mode, it is more likely that lsphp is not allowed to read /opt/lsws/conf/php.ini.

You can change the lsphp command to use php.ini at a different location. copy php.ini to /opt/lsws/conf/php/php.ini. change command to "$SERVER/fcgi-bin/lsphp -c /opt/lsws/conf/php/php.ini", make sure permission for /opt/lsws/conf/php has been set to 0755.

[surfman]

as a test, I set /opt/lsws/conf 755, then, eaccelerator is working.

but when I follow your instruction,
1) copy php.ini to /opt/lsws/conf/php/php.ini
2) change command to "$SERVER_ROOT/fcgi-bin/lsphp -c /opt/lsws/conf/php/php.ini at LSAPI App settings in admin control panel
3) also, I modify
zend_extension="../lib/eaccelerator.so"
to
zend_extension="/opt/lsws/lib/eaccelerator.so"
4) set back /opt/lsws/conf 700
5) set /opt/lsws/conf/php 755

eaccelerator stops working.

any suggestion for extra steps? thanks.
