memcached安装+绑定访问ip

安装：

1.由于memcached是基于libevent的，需要安装libevent,libevent-devel

$yum -y install libevent libevent-devel

2.下载解压emcached

$ wget http://memcached.org/latest

$ tar -zxvf memcached-1.4.32.tar.gz

3.编译安装

$ cd memcached-1.4.34

$ ./configure

$ make

$ make test

$ make install

4.编写memcached服务启停脚本

$ vim /etc/init.d/memcached

-#! /bin/sh

-#

-# chkconfig: - 55 45

-# description: The memcached daemon is a network memory cache service.

-# processname: memcached

-# config: /etc/sysconfig/memcached

-# pidfile: /var/run/memcached/memcached.pid

-# Standard LSB functions

-#. /lib/lsb/init-functions

-# Source function library.

-. /etc/init.d/functions

-PORT=11211

-USER=memcached

-MAXCONN=1024

-CACHESIZE=64

-OPTIONS=""

-IP=127.0.0.1

-if [ -f /etc/sysconfig/memcached ];then

• . /etc/sysconfig/memcached
  
  -fi

-# Check that networking is up.

-. /etc/sysconfig/network

-if [ "$NETWORKING" = "no" ]

-then

• exit 0
  
  -fi

-RETVAL=0

-prog="memcached"

-pidfile=${PIDFILE-/var/run/memcached/memcached.pid}

-lockfile=${LOCKFILE-/var/lock/subsys/memcached}

-start () {

echo -n $"Starting $prog: "

-# Ensure that /var/run/memcached has proper permissions

if [ "stat -c %U /var/run/memcached" != "$USER" ]; then

chown $USER /var/run/memcached

fi

daemon --pidfile ${pidfile} /usr/local/bin/memcached -d -l $IP -p $PORT -u $USER  -m $CACHESIZE -c $MAXCONN -P ${pidfile} $OPTIONS
RETVAL=$?
echo
[ $RETVAL -eq 0 ] && touch ${lockfile}

}

stop () {

echo -n $"Stopping $prog: "

killproc -p ${pidfile} /usr/local/bin/memcached

RETVAL=$?

echo

if [ $RETVAL -eq 0 ] ; then

rm -f ${lockfile} ${pidfile}

fi

}

restart () {

stop

start

}

-# See how we were called.

case "$1" in

status -p ${pidfile} memcached

;;

*)

echo $"Usage: $0 {start|stop|status|restart|reload|force-reload|condrestart|try-restart}"

RETVAL=2

;;

esac

exit $RETVAL

5.启动服务+开机自动重启

$ service memcached start

$ chkconfig memcached on

6.绑定内网：

1).使用-l参数指定访问的地址.

2).使用iptables规则匹配访问的地址.
