Why XCache?
see Introduction
Where Is ./configure?
Well... you have to install php first, which gives you "phpize" executable(script), and do
~/src/xcache $ phpize (generating configure) ~/src/xcache $ ./configure --help ~/src/xcache $ ./configure --enable-...
How to install from source?
follow the instructions in GettingSource, BuildingFromSource, InstallingAsPhpExtension
What if i'm getting "undefined symbol"
If your php is configured --enable-versioning, disable it. It's broken. If you insist on versioning, build XCache as a static module of php.
Apache2 keeps getting segmentation faults with cache larger than 4M
Set "xcache.readonly_protection = On" in php.ini
I get "Cannot dynamically load xcache.so"
When u get PHP Warning: Unknown(): Cannot dynamically load xcache.so - dynamic modules are not supported in Unknown on line 0, it's because your php is running on a arch/os that don't support dynamic load library(aka modules), to solve it:
~ $ mv xcache php-src/ ~ $ cd php-src/ ~/php-src $ ./buildconf --force ~/php-src $ ./config.nice --enable-xcache --enable-xcache-coverager (or if you havn't run configure yet, use:) ~/php-src $ ./configure --enable-xcache --enable-xcache-coverager --your-options ~/php-src $ make all ~/php-src $ make install
I see jumpy "hits" in admin page
It is possible that u see jumpy "hits" count in admin page. i.e.: you see hits=300,000 on first load of admin page, but dropped to hits=1 in 2nd reload and back to hits=312,456 on 3rd load.
This is because you have php started in different group which does not share shm with each other. But keep in mind that all childs in 1 group will share shm. So how to check and make it 1 group only?
Checking:
Good Exmaple
$ pstree -p
| |-supervise(4913)---lighttpd(23975)-+-php-cgi(23979)-+-php-cgi(23981)
| | | |-php-cgi(23982)
| | | |-php-cgi(23983)
| | | `-php-cgi(23984)
Bad Exmaple
$ pstree -p
| |-supervise(4913)---lighttpd(23975)-+-php-cgi(23979)-+-php-cgi(23981)
| | | |-php-cgi(23982)
| | | |-php-cgi(23983)
| | | `-php-cgi(23984)
| +-php-cgi(23980)-+-php-cgi(23985)
| | | |-php-cgi(23986)
| | | |-php-cgi(23987)
| | | `-php-cgi(23988)
