Compiling PHP extensions for installing memcached and Memcache

One: Install Memcache

1: Compile and install Libevent

wget https://github.com/downloads/libevent/libevent/libevent-2.0.21-stable.tar.gz
TAR-ZXVF libevent-2.0.21-stable.tar.gz
CD libevent-2.0.21-stable
./configure--prefix=/usr/local/libevent
Make
Make Isntall

2: Compile and install memcached

wget http://www.memcached.org/files/memcached-1.4.19.tar.gz
TAR-ZXVF memcached-1.4.19.tar.gz
CD memcached-1.4.19
./configure-with-libevent=/usr/local/libevent/-prefix=/usr/local/memcached
Make
Make install

3: Start memcached:

/usr/local/memcached/bin/memcached-d-M 64-u root-p 11211

The following is the memcached command-related parameter details:
The-D option is to start a daemon,
-M is the amount of memory allocated to Memcache, in megabytes, 10MB,
-U is the user running memcache, this is root,
-L is the server IP address that is listening, and if there are multiple addresses, this specifies the server's IP address 192.168.0.200,
-P is the port that sets the Memcache listener, which is set to 12000, preferably 1024 or more ports,
The-c option is the maximum number of concurrent connections to run, the default is 1024, set 256 here, according to the load of the server to set,
-P is the set to save memcache PID file, I am here to save in/tmp/memcached.pid, can also start multiple daemons, but the port can not repeat.

II: Installing memcache PHP Extensions

wget http://pecl.php.net/get/memcache-3.0.8.tgz
TAR-ZXVF memcache-3.0.8.tgz
CD memcache-3.0.8
/usr/local/php/bin/phpize
./configure--with-php-config=/usr/local/php/bin/php-config
Make
Make install
Ll/usr/local/php/lib/php/extensions/no-debug-non-zts-20090626/memcache.so # to see if the extension so file is generated
-rwxr-xr-x 1 root root 422219 May 9 10:29/usr/local/php/lib/php/extensions/no-debug-non-zts-20090626/memcache.so #文件存在

Vim/usr/local/php/etc/php.ini #加入扩展
Extension_dir = "/usr/local/php/lib/php/extensions/no-debug-non-zts-20090626/"
Extension = "memcache.so"

Reboot PHP:

I'm using Nginx.

KILL-USR2 ' Cat/usr/local/php/var/run/php-fpm.pid ' #平滑重启php

/usr/local/php/bin/php-m #查看php是否加入了memcache扩展 (or perform phpinfo function to see if memcache extension exists)
There are already memcach extensions, done!
