安装&配置

wget http://memcached.org/latest -O memcached.tar.gz
tar -zxvf memcached.tar.gz
cd memcached
./configure --prefix=/usr/local/memcached
make && sudo make install
ln -sf /usr/local/memcached/bin/memcached /usr/bin/memcached

如果不存在`/var/lock/subsys`，则创建`mkdir -p /var/lock/subsys`

配置系统服务

添加文件：vim /etc/init.d/memcached

#! /bin/bash
#
# memcached:    MemCached Daemon   
#
# chkconfig:    - 90 25

#如果IP为127.0.0.1则限制仅本机可访问
#如果IP为本机的内网IP，则只能内网能访问
#IP为应用程序访问Memcached使用的IP，一般为127.0.0.1或本机内网IP或本机外网IP
IP=127.0.0.1
PORT=11211
USER=root

CACHESIZE=64
OPTIONS=""

prog="memcached"

start () {
    echo -n $"Starting $prog: "
    /usr/local/memcached/bin/memcached -d -l $IP -p $PORT -u $USER -m $CACHESIZE -c $MAXCONN -P /var/run/memcached.pid $OPTIONS
    if [ "$?" != 0 ] ; then
        echo " failed"
        exit 1
    else
        touch /var/lock/subsys/memcached
        echo " done"
    fi
}

stop () {
    echo -n $"Stopping $prog: "
    if [ ! -e /var/run/$prog.pid ]; then
        echo -n $"$prog is not running."
        exit 1
    fi
    kill `cat /var/run/memcached.pid`
    if [ "$?" != 0 ] ; then
        echo " failed"
        exit 1
    else
        rm -f /var/lock/subsys/memcached
        rm -f /var/run/memcached.pid
        echo " done"
    fi
}

restart () {
    $0 stop
    sleep 2
    $0 start
}

# See how we were called.
case "$1" in
    start)
        start
        ;;
    stop)
        stop
        ;;
    restart|reload)
        restart
        ;;
    *)
        echo $"Usage: $0 {start|stop|status|restart|reload}"
        exit 1
        ;;
esac

exit $?

赋予可执行权限：chmod +x /etc/init.d/memcached

防火墙设置

#设置规则
vim /etc/sysconfig/iptables

#如果限定某些机器能访问可如下设置：
-A INPUT -s 127.0.0.1,10.170.238.137,123.7.213.222/32 -p udp -m udp --dport 11211 -j ACCEPT
-A INPUT -s 127.0.0.1,10.170.238.137,123.7.213.222/32 -p tcp -m tcp --dport 11211 -j ACCEPT
-A INPUT -p tcp -m tcp --dport 11211 -j DROP
-A INPUT -p udp -m udp --dport 11211 -j DROP

#重启iptables使得规则生效
service iptables restart

启动

/etc/init.d/memcached start
