Installation of Memcache server under Linux

 LinuxunderMemcacheinstallation of the server Environmental Requirements:

Installing memcached requires Libevent library support, so check to see if Libevent is installed before installing memcached. The test environment also requires PHP support, and this article assumes that PHP is already installed in the/usr/local/php directory.

Server side is mainly installed Memcache server side, Memcache use libevent this library for socket processing, so also need to install libevent.

memcached : http://www.danga.com/memcached/

libevent : http://monkey.org/~provos/libevent/

Installation configuration:

Download libevent:

Mkdir/home/oldboy/tools-p
cd/home/oldboy/tools/
wget http://www.monkey.org/~provos/libevent-1.4.13-stable.tar.gz

Install Libevent:

Tar zxf libevent-1.4.13-stable.tar.gz

CD libevent-1.4.13-stable

./configure –-prefix=/usr ; echo $?

Make && make install; echo $?

Cd..

Check if the libevent is installed successfully:

[Email protected] tools]# ls-al/usr/lib |grep libevent

Download the installation memcached and specify the location of the libevent:

Cd/home/oldboy/tools

wget http://memcached.googlecode.com/files/memcached-1.4.13.tar.gz

Tar zxf memcached-1.4.13.tar.gz

CD memcached-1.4.13

./configure --with-libevent=/usr ; echo $?

Make && make install; echo $?

Cd..

After the installation is complete, the mencached will be found in the/usr/local/bin/directory

such as:/usr/local/bin/memcached-d-M 200-u root-l 192.168.1.91-p 12000-c1000-p/tmp/memcached.pid

The relevant explanations are as follows:
The-D option is to start a daemon,
-M is the amount of memory allocated to Memcache, in megabytes, 200MB
-U is the user running memcache, I am root here
-L is the server IP address of the listener, if there are multiple addresses, I specify the IP address of the server 192.168.1.91
-P is the port that sets Memcache listening, I set here 12000, preferably more than 1024 ports
The-c option is the maximum number of concurrent connections to run, the default is 1024, and I set the 1000
-P is set to save memcache PID file, I am here to save in/tmp/memcached.pid

To stop the memcache process:

Kill ' Cat /tmp/memcached.pid'

Add to boot:

Cat >>/etc/rc.local<<eof

#memcached start along with SYS by Lisp

Memcached-p 11211-u root-m 16m-c 10240-p/var/run/memcached_11211.pid-d

Memcached-p 11212-u root-m 16m-c 10240-p/var/run/memcached_11212.pid-d
