wget http://memcached.googlecode.com/files/memcached-1.4.10.tar.gz TAR-ZXVF memcached-1.4.10.tar.gz CD memcached-1.x.x ./configure #到这一步报错了如下: #configure: Error:libevent is required. You can get it from http://www.monkey.org/~provos/libevent/

Memcache used libevent This library for socket processing, so also need to install the latest version of Libevent,libevent is libevent-2.0. (If your system has libevent installed, you may not need to install it)
Official website: http://www.monkey.org/~provos/libevent/

It's just libevent.

Test whether the Libevent is installed successfully

The code is as follows	Copy Code
Ls-al/usr/lib | grep libevent

Come out a big list of things, said the names installed

Next Install Memcache

The code is as follows	Copy Code
./configure–with-libevent=/usr

Test whether the memcached was successfully installed

The code is as follows	Copy Code
ls-al/usr/local/bin/mem* -rwxr-xr-x 1 root root 203321 01-05 08:03/usr/local/bin/memcached

Description of Successful Installation

Basic Settings for memcached:
1. Start the Memcache server side:
#/usr/local/bin/memcached-d-M 10-u root-l 192.168.0.200-p 12000-c 256-p/tmp/memcached.pid

The-D option is to start a daemon,
-M is the amount of memory allocated to Memcache, in megabytes, I am 10MB here,
-U is the user running memcache, I am here root,
-L is a listening server IP address, if there are more than one address, I specify the IP address of the server 192.168.0.200,
-P is the port that sets the memcache listening, I set 12000 here, preferably 1024 or more ports,
The-c option is the maximum number of concurrent connections to run, the default is 1024, I set 256 here, according to the load of your server to set,
-P is set to save the Memcache pid file, which I am here to save in/tmp/memcached.pid,

2. If you want to end the memcache process, execute:

The code is as follows	Copy Code
# Kill ' Cat/tmp/memcached.pid '

You can also start multiple daemons, but the ports cannot be duplicated.

3. Restart Apache,service httpd restart or nginx

Installing Memcache PHP Extensions
1. Select the Memcache version that you want to download in Http://pecl.php.net/package/memcache.
2. Install the PHP memcache extension

The code is as follows	Copy Code
wget http://pecl.php.net/get/memcache-2.2.6.tgz Tar vxzf memcache-2.2.6.tgz CD memcache-2.2.6.tgz /usr/local/php/bin/phpize ./configure–enable-memcache–with-php-config=/usr/local/php/bin/php-config–with-zlib-dir Make Make install

3. The above installation will have a similar hint:

The code is as follows	Copy Code
Installing Shared extensions:/usr/local/php/lib/php/extensions/no-debug-non-zts-2007xxxx/

4. Change the Extension_dir = "./" in php.ini to

The code is as follows	Copy Code
Extension_dir = "/usr/local/php/lib/php/extensions/no-debug-non-zts-2007xxxx/"

5. Add a row to load the memcache extension: extension=memcache.so

Memcache Environment test:
run the following PHP file, if the output is a test!, it means that the environment has been built successfully. Start to appreciate the charm of memcache!

code is as follows	copy code
<? PHP $ MEM = new Memcache; $mem->connect ("127.0.0.1″, 11211)"; $mem->set (' key ', ' This is a test! ', 0, 60); $val = $mem->get (' key '); Echo $val; ?
