Remember to manually install pecl extension-memcache

Download zlib (because php's memcache extension module uses the function» zlib to support data compression, Zlib must be installed to install this module. ): Http://sourceforge.net/projects/libpng/files/zlib/1.2.5/zlib-1.2.5.tar.gz/download

Download memcache php extensions: http://pecl.php.net/get/memcache-3.0.6.tgz

Zlib is not installed by default in Ubuntu11.04. Therefore, you must first install zlib.

 

Tar-xzvf zlib-1.2.5.tar.gz
Cd zlib-1.2.5
./Configure -- prefix =/usr/dev/zlib
Make
Make installl

 

 

Then install memcache

 

Tar-xzvf memcache-3.0.6.tgz
Cd memcache-3.0.6
/Usr/dev/php-5.3.6/bin/phpize // use phpize to generate the configure file, phpize is compiled by pecl, phpize is generally in the bin directory of the php installation directory, you can refer to here: http://www.cnblogs.com/wangtao_20/archive/2011/3/16.html
In this step, the following error may be reported: Cannot find autoconf. Please check your autoconf installation
This is because autoconf has not been installed or the autoconf settings in phpize are incorrect. First, use dpkg-l to check whether autoconf has been installed. If autoconf is not installed, download and install it:
Download autoconf http://ftp.gnu.org/gnu/autoconf/autoconf-2.68.tar.gz
Tar-xzvf autoconf-2.68.tar.gz
Cd autoconf-2.68
./Configure -- prefix =/usr/dev/pecl/autoconf
Make
Make install after installation is successful, you need to change the phpsize
Sudo gedit/usr/dev/php-5.3.6/bin/phpize
Find test-z "$ PHP_AUTOCONF" and test-z "$ PHP_AUTOHEADER", as shown in the following example:
Test-z "$ PHP_AUTOCONF" & PHP_AUTOCONF = autoconf
Test-z "$ PHP_AUTOHEADER" & PHP_AUTOHEADER = autoheader
Changed:
Test-z "$ PHP_AUTOCONF" & PHP_AUTOCONF =/usr/dev/pecl/autoconf/bin/autoconf
Test-z "$ PHP_AUTOHEADER" & PHP_AUTOHEADER =/usr/dev/pecl/autoconf/bin/autoheader
Save and exit
Back to memcache-3.0.6 directory

/Usr/dev/php-5.3.6/bin/phpize // execution successful, a configure file is generated in the current directory
. // Configure -- with-php-config =/usr/dev/php-5.3.6/bin/php-config -- with-zlib-dir =/usr/dev/zlib -- with-apxs =/ usr/dev/apache/bin/apxs -- with-gettext -- enable-socket -- enable-memcache -- enable-sysvshm -- enable-shmop
Make
Make install

 

 

Open the php. ini file, in this example/usr/dev/php-5.3.6/lib/php. ini

Add the following two rows:

Extension_dir =/usr/dev/php5.3.6/lib/php/extensions/no-debug-non-zts-20090626 "extension = memcache. so

 

Of course, you can also

/Usr/dev/php5.3.6/lib/php/extensions/no-debug-non-zts-20090626/memcache. so to/usr/dev/php5.3.6/lib/php/extensions/memcache. so or create a pointer to/usr/dev/php5.3.6/lib/php/extensions/no-debug-non-zts-20090626/memcache. so hard link/usr/dev/php5.3.6/lib/php/extensions/memcache. so

 

 

Then add the following two lines to php. ini:

Extension_dir =/usr/dev/php5.3.6/lib/php/extensions "extension = memcache. so

Disable saving php. ini, restart apache, and use memcache extension in php code.
