4. I have done all but it doen’t work, I am running 5.3.2, I had to recompile php to support libcurl, now I broken memcached and I am stuck with it.

5. @Islam: Which Linux Version you are using. You said it doesn’t work and in mean time you said when you compile php with libcurl it broke memcached?

   Regards,

6. @Souhail: it’s a centos, kernel 2.6.18 ..
   there is no relationship between libcurl and memcached, the only thing is that after I recompiled PHP, libcurl worked, and memcached not, I tried many times with too versions of the package and nothing! PHP is version 5.3.2

7. @Islam: I knew there is no relationship between libcurl and memcached. All you have to do is recompile PHP and then reinstall memcached using the source because it uses phpize to determine the PHP version, so you need to reinstall memcached everytime you recompile PHP.
   It will be good if you posted any error which you facing while installing memcached

8. Thank you Sohail, I got it working now.
   I was phpizing against the wrong version of php, .. another thing is that extension = “memcache.so” doesn’t work with the ” ” , maybe you should fix that in the tutorial.
   thank you very much for your help.

9. This was right on the money. Thanks for posting it.

10. Thanks. It worked for me

11. The check step could be done before starting apache.
    And if you are using drupal, dont forget to set:

    memcache.hash_strategy = “consistent”

    for drupal memcache module.

12. Had these errors when ./configure

    checking for the location of ZLIB… no
    checking for the location of zlib… configure: error: memcache support requires ZLIB. Use –with-zlib-dir= to specify prefix where ZLIB include and library are located

    did this :
    ./configure –with-zlib-dir=/usr/include

    worked fine .

    when i typed make …

    /usr/src/memcache-2.2.5/memcache.c:878: error: ‘Z_OK’ undeclared (first use in this function)

    any clues ?

13. @ronan: check whether you have install zlib-devel package.

    how to fix this

16. suvro, i have the same problem here, you found a solution?

17. Same problem here too 🙁

18. Thanks a million, you save my life.. Thanx n keep it up.

19. Hi,
    I get this conflict message when I run the command

    $rpm -Uhv http://apt.sw.be/redhat/el5/en/x86_64/rpmforge/RPMS/rpmforge-release-0.3.6-1.el5.rf.x86_64.rpm

    Any reason why I do not see the expected output?

20. Thanks man. You came as a rescue for me. Cheers.

21. Some friend segest me to not use memcached because it will burden your server with many file. is’t true or not ?

22. Of course not, it keeps cache on the memory, not in files.

23. Hi

    I followed the tut, and everything worked fine until i got to check is memcache extension loaded in php then i get this error :

    [root@s******** memcache-2.2.5]# php -i | grep memcache
    Failed loading /usr/local/lib/php/extensions/non-debug-non-zts-xxx/xcache.so: /usr/local/lib/php/extensions/non-debug-non-zts-xxx/xcache.so: cannot open shared object file: No such file or directory
    PHP Warning: PHP Startup: Unable to load dynamic library ‘/usr/lib64/php/modules/memcache.so’ – /usr/lib64/php/modules/memcache.so: cannot open shared object file: No such file or directory in Unknown on line 0
    PWD => /usr/src/memcache-2.2.5
    _SERVER[“PWD”] => /usr/src/memcache-2.2.5
    _ENV[“PWD”] => /usr/src/memcache-2.2.5

    I think the first to lines referencing xcache are from a deleted attempt to install xcache.
    the memcache.so file is where it says it is.
    all that is in the file is : []ELF-

    Has anyone got an idea what has gone wrong please
    

24. sorry ment so say im running centos 5.7
    my kernel is Linux 2.6.18-274.17.1.el5 on x86_64

25. nice tutorial – thx

26. Very good tutorial. Thank you very much.

27. Hello,

    I have a LAMP(Linux, apache, mysql, php) server i want to use memcahe for better performance but my web server and db server are on different machine and i don’t know on which machine i should install memcache and php-memcache rpm ?

28. @you need to install memcached on both your web and db server. Then compile php with memcache module on web server only. Make your memcached from db server accessiable and configure your php to access it as memcached using IP address/port of db server. We have done this with individual memcached servers as middle server between web and db server.
