Example of managing memcached service scripts in Linux

Memcached requires libevent support, so you need to first check to see if Libevent is installed.

The following is the memcached installation process:

# tar zvxf memcached-1.4.9.tar.gz
# CD memcached-1.4.9
#./configure--prefix=/usr/local/memcached
# make
# make Install

Start memcached:

#/usr/local/memcached/bin/memcached-d-M 128-l 127.0.0.1-p 11211-u Root

Parameter 128 Specifies the amount of memory used

The next step is to install Memcache extensions for PHP:

# gzip-d Memcache-2.2.6.tgz
# tar XVF Memcache-2.2.6.tar
# CD memcache-2.2.6
#/usr/local/php/bin/phpize
#./configure--with-php-config=/usr/local/php/bin/php-config--enable-memcache
# make
# make Install

Finally, add the following configuration information to the php.ini file:

Extension_dir = "/usr/local/php/lib/php/extensions/no-debug-non-zts-20060613/"
Extension=memcache.so

Remark:/usr/local/php/lib/php/extensions/no-debug-non-zts-20060613/This path may be different, whichever is the same in your machine.

Memcached has been installed in Linux and is deployed to the/usr/local/memcached path, next we start to install service management scripts for it to start and stop.

First of all, through VI in the/ETC/RC.D/INIT.D path to create a new script file named memcached, the command is as follows:

Vi/etc/rc.d/init.d/memcached

Then, write the shell script to it as follows:

#!/bin/sh
#
# chkconfig:2345 90 50
# description:memcached Service Daemon
#
# processname:memcached
#
# Source function library.
. /etc/rc.d/init.d/functions
. /etc/sysconfig/network
#[${networking} = ' No '] && exit 0
#[-r/etc/sysconfig/dund] | | Exit 0
#. /etc/sysconfig/dund
#[-Z "$DUNDARGS"] && exit 0

Memcached= "/usr/local/memcached/bin/memcached"

Start ()
{
Echo-n $ "Starting Memcached:"
Daemon $MEMCACHED-u daemon-d-M 32-l 127.0.0.1-p 11211-c 256-p/tmp/memcached.pid
Echo
}
Stop ()
{
Echo-n $ "Shutting down Memcached:"
Killproc memcached
Echo
}

[f $MEMCACHED] | | Exit 1
# How we were called.
Case "$" in
Start
Start
;;
Stop
Stop
;;
Restart)
Stop
Sleep 3
Start
;;
*)
echo $ "Usage: $ {Start|stop|restart}"
Exit 1
Esac
Exit 0

After saving exit VI, execute the following command to install the script

chmod 777/etc/rc.d/init.d/memcached
Chkconfig--add memcached
Chkconfig--level 235 memcached on

You can then check to see if the installation was successful by using the following command

Chkconfig--list | grep memcached
Service memcached Start
Service memcached Stop
Service memcached Restart
