InstallConfiguration

1.InstallLibevent
# Tar zxf libevent-1.4.6-stable.tar.gz
# Cd libevent-1.4.6-stable
#./Configure -- prefix =/usr/local/servers/libevent
# Make & make install

2.InstallMemcached
# Tar zxvf memcached-1.2.6.tar.gz
# Cd memcached-1.2.6
#./Configure -- prefix =/usr/local/servers/memcached -- with-libevent =/usr/local/servers/libevent
# Make & make install

3. Run memcached
#/Usr/local/servers/memcached-d-m 128-l localhost-p 11211-u root

-D run memcached in daemon mode;
-M: Set the memory size available for memcached, in MB;
-L set the IP address of the listener. If it is a local machine, this parameter is usually not set;
-P: Set the listening port. The default value is 11211. Therefore, you can leave this parameter unspecified;
-U indicates the user;

If you encounter problems when running memcached, the error prompt is as follows:

/Usr/local/servers/memcached/bin/memcached: error while loading shared libraries: libevent-1.4.so.2: cannot open shared object file: No such file or directory

Run LD_DUBUG = libs to know the library loading path when memcached is started. The details are as follows:

# LD_DEBUG = libs/usr/local/servers/memcached/bin/memcached-v
10929: find library = libevent-1.4.so.2 [0]; searching
10929: search cache =/etc/ld. so. cache

10929: trying file =/usr/lib/libevent-1.4.so.2
10929:

Then create a link for the libevent-1.4.so.2 and then run memcached:
# Ln-s/usr/local/servers/libevent/lib/libevent-1.4.so.2/lib/libevent-1.4.so.2

4.InstallPhp memcacheExtension

You can use the pecl that comes with php.InstallProgram
#/Usr/local/servers/php5/bin/pecl install memcache

You can also use the source codeInstall
# Tar zxf memcache-2.2.3.tgz
# Cd memcache-2.2.3
#/Usr/local/servers/php5/bin/phpize
#. /Configure -- enable-memcache =/usr/local/servers/memcached -- with-php-config =/usr/local/servers/php5/bin/php-config -- with-apxs2 =/ usr/sbin/apxs
# Make & make inst

InstallThere will be a prompt like this after:
Installing shared extensions:/usr/local/servers/php5/lib/php/extension/ no-debug-non-zts-20060922/

Remember this, modify php. ini, and

Extension_dir = "./"
Change
Extension_dir = "/usr/local/servers/php5/lib/php/extensions /"

Add a row
Extension = "no-debug-non-zts-20060922/memcache. so"

5. Use phpinfo to view

Windows:

Download the stable version of memcache for windows and decompress it to a disk, for example, in d: \ memcached

2. Enter d: \ memcached \ memcached.exe-d install on the terminal (that is, the cmd command interface)Install

3. Enter c: \ memcached \ memcached.exe-d start to start.

NOTE: in the future, memcached will be used as a windows Service and will be automatically started every time it is started. In this way, the server hasInstallFinished.

4. Download php_memcache.dll. Find the corresponding php version file by yourself.

5. Add a line of extension = php_memcache.dll to php. ini.

6. Restart Apache and check phpinfo. If memcache exists, it indicatesInstallSuccessful!

Test Module

$ Memcache = new Memcache;
$ Memcache-> connect ('localhost', 12000) or die ("cocould not connect ");

$ Version = $ memcache-> getVersion ();
Echo "Server's version:". $ version ."
\ N ";

$ Tmp_object = new stdClass;
$ Tmp_object-> str_attr = 'test ';
$ Tmp_object-> int_attr = 123;

$ Memcache-> set ('key', $ tmp_object, false, 10) or die ("Failed to save data at the server ");
Echo "Store data in the cache (data will expire in 10 seconds)
\ N ";

$ Get_result = $ memcache-> get ('key ');
Echo "Data from the cache:
\ N ";

Var_dump ($ get_result );

?>

Display result:

Server's version: 1.4.4-14-g9c660c0
Store data in the cache (data will expire in 10 seconds)
Data from the cache:

Object (stdClass) [3] public 'str _ attr '=> string 'test' (length = 4) public 'int _ attr' => int 123

----------------

The server side is memcached, and the client side can be considered as php_memcache.dll.

Php_memcache.dll provides a set of functions for caching, extraction, and deletion of cache operations. Through these functions, the data is finally stored inInstallA machine with the memcached service can be a local machine or a machine on another network.
