How to install Memcached on CentOS + Memcached PECL (Update : 2011.03.22)

Category

From previous HOW TO - http://www.bxtra.net/Articles/2010-04-27/How-install-Memcached-CentOS-DirectAdmin-installed-Memcached-PECL I just think that I should note an update how to install Memcached so that I, myself, can follow the steps here and get the latest version. The steps are almost exactly to my previous Memcached PECL installed. Only a few changes to install an updated version.

Get Libevent which is require to install Memcached. Their homepage is here -> http://www.monkey.org/~provos/libevent/

wget http://monkey.org/~provos/libevent-2.0.10-stable.tar.gz
tar -xvf libevent-2.0.10-stable.tar.gz
cd libevent-2.0.10-stable
./configure;make;make install;

Then, get Memcached from http://memcached.org

wget http://memcached.googlecode.com/files/memcached-1.4.5.tar.gz
gunzip memcached-1.4.5.tar.gz
tar -xvf memcached-1.4.5.tar
cd memcached-1.4.5
./configure;make;make install;

For me, I got an error below when try to run memcached :

memcached: error while loading shared libraries: libevent-2.0.so.5: cannot open shared object file: No such file or directory

So, I did steps below :

ln -s /usr/local/lib/libevent-2.0.so.5 /usr/lib64/libevent-2.0.so.5

Once you're done with that, try run

memcached -d -u nobody -m 1024 127.0.0.1 -p 11211

This is not done yet, you need to let PHP knows to be able to use memcached.

wget http://launchpad.net/libmemcached/1.0/0.48/+download/libmemcached-0.48.tar.gz
tar xvfz libmemcached-0.48.tar.gz
cd libmemcached-0.48
./configure

You will see screen below :

Then, run

make && make install

Then install Memcached PECL with below command :

pecl install memcached

Once it's done, you may notice that the extension path is different to what we normally see. What you will see is :

/usr/local/php5/lib/php/extensions/no-debug-non-zts-20090626

But what most module for PHP 5.3 installed will compile into

/usr/local/lib/php/extensions/no-debug-non-zts-20090626

Therefore, make sure you get the right path for extension_dir Edit php.ini to have lines below : (Make sure the line "extension_dir" is there or you need a full path to memcached.so )

extension_dir = "/usr/local/lib/php/extensions/no-debug-non-zts-20090626"
extension=memcached.so

Then, restart HTTP and check PHP Status.. You will see Memcached info as below:

In case you need to use Memcached as a session handler. (Not require) Then, you need to edit php.ini and set variable below :

session.save_handler=memcached
session.save_path="127.0.0.1:11211"

Now, you're done install Memcached on the server. However, you need to modify some code in your website script to make use of Memcached.

Server Information - Software
- CentOS 5.5
- DirectAdmin 1.38
- Apache 2.2.17
- PHP 5.3.6
- MySQL 5.5.9

how to fix?

Got same error with new

Got same error with new libmemcached 1.0.6 . Still, I don't have time to check it now cause I don't use memcached PECL anymore. Will check it again later.

I have update

The accepted answer was to place "#define __STDC_FORMAT_MACROS" at the top of the file. I did so for auto.cc and was able to compile that particular file

Well then. Apologies for the thread. Seems there was a similar issue in the gearmand module, and exporting the compiler environment variables to use gcc 4.4 works.

Just tested with version 1.0

Just tested with version 1.0.7 and it works ok now.

Update : Well spoke too soon.. "./configure" was now compiled ok but after ran "make & make install" , below is the error I got : CXX libhashkit/libmemcached_libmemcached_la-strerror.lo CXX libhashkit/libmemcached_libmemcached_la-string.lo CXX libhashkit/libmemcached_libmemcached_la-nohsieh.lo CXX libmemcached/libmemcached_libmemcached_la-allocators.lo CXX libmemcached/libmemcached_libmemcached_la-analyze.lo CC libmemcached/libmemcached_libmemcached_la-array.lo CXX libmemcached/libmemcached_libmemcached_la-auto.lo libmemcached/auto.cc: In function 'memcached_return_t text_incr_decr(memcached_server_st*, bool, const char*, size_t, uint64_t, bool)': libmemcached/auto.cc:73: error: expected `)' before 'PRIu64' make[1]: *** [libmemcached/libmemcached_libmemcached_la-auto.lo] Error 1 make[1]: Leaving directory `/root/libmemcached-1.0.7' make: *** [all] Error 2

If it helps, the main problem

If it helps, the main problem with compiling libmemcached on CentOS 5.5 for me was the GCC version is too old. You can use the following to install an updated version which should enable you to compile it: yum install gcc44 gcc44-c++ libstdc++44-devel After the above installs, export the following environment variables to tell the configure script to use the newer GCC version (they install in parallel): export CC=/usr/bin/gcc44 export CXX=/usr/bin/g++44 -Adam

Thanks Adam, I followed your

Thanks Adam, I followed your instruction and it does work now :) Tested with version 1.0.8.

I had the same issue

zilb was in /lib64 and autoconf was not able to locate, intalling zlib-devel gave it direct my giving pkgconfig.
