CentOS-6.4安装Memcached

由于项目上线后需要考虑分布式，SESSION准备放在Memcache来同步，下面是一些配置及随手的记录。

1、安装libevent

# blog.phpha.com
wget http://monkey.org/~provos/libevent-1.4.14b-stable.tar.gz
tar zxvf libevent-1.4.14b-stable.tar.gz
cd libevent-1.4.14b-stable
./configure --prefix=/usr/local/libevent/
make && make install
ln -s /usr/local/libevent/lib/libevent-1.4.so.2 /lib/libevent-1.4.so.2
# blog.phpha.com

2、安装Memcached

# blog.phpha.com
wget http://memcached.googlecode.com/files/memcached-1.4.15.tar.gz
tar zxvf memcached-1.4.15.tar.gz
cd memcached-1.4.15
./configure --prefix=/usr/local/memcached/ --with-libevent=/usr/local/libevent/
make && make install
# blog.phpha.com

3、启动Memcached

# blog.phpha.com
/usr/local/memcached/bin/memcached -d -m 64 -u root -l 127.0.0.100 -p 11211 -c 128 -P /tmp/memcached.pid
# blog.phpha.com

4、为了方便管理，写个SHELL脚本吧。

# blog.phpha.com
# http://blog.phpha.com
# 以下内容摘自互联网
vi /etc/rc.d/init.d/memcached
# blog.phpha.com

# blog.phpha.com
#!/bin/sh
#
# memcached:    MemCached Daemon
#
# chkconfig:    - 90 25
# description:  MemCached Daemon
#
# 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
start()
{
        echo -n $"Starting memcached: "
        daemon $MEMCACHED -u daemon -d -m 64 -l 127.0.0.100 -p 11211 -c 128 -P /tmp/memcached.pid
        echo
}
stop()
{
        echo -n $"Shutting down memcached: "
        killproc memcached
        echo
}
MEMCACHED="/usr/local/memcached/bin/memcached"
[ -f $MEMCACHED ] || exit 1
# See how we were called.
case "$1" in
        start)
                start
                ;;
        stop)
                stop
                ;;
        restart)
                stop
                sleep 3
                start
                ;;
        *)
                echo $"Usage: $0 {start|stop|restart}"
                exit 1
esac
exit 0
# blog.phpha.com

5、添加Memcached开机启动

# blog.phpha.com
cd /etc/rc.d/init.d/
chmod 777 memcached
chkconfig --add memcached
chkconfig --level 235 memcached on
chkconfig --list | grep memcached
# blog.phpha.com

6、Memcached使用经过上面的步骤，可以如下进行开启、停止、重启等操作。

# blog.phpha.com
service memcached start
service memcached stop
service memcached restart
# blog.phpha.com
