安装Memcached步骤: 

1.编译安装Libevent 

cd ~  

wget https://github.com/downloads/libevent/libevent/libevent-2.0.19-stable.tar.gz  

tar -zxvf libevent-2.0.19-stable.tar.gz  

cd libevent-2.0.19-stable  

./configure --prefix=/usr/local/libevent/  

make  

make install  

ln -s /usr/local/libevent/lib/libevent-2.0.so.5  /lib64/libevent-2.0.so.5  

2.安装Memcache 

cd ~  

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

tar -zxvf memcached-1.4.13.tar.gz  

cd memcached-1.4.13  

./configure --prefix=/usr/local/memcached --with-libevent=/usr/local/libevent/  

make  

make install  

3.编写memcached服务启停脚本 

# cd /etc/init.d  

vi memcached  

脚本内容如下： 

#!/bin/sh  

# Startup script for the server of memcached  

#http://blog.rekfan.com/?p=172  

# processname: memcached  

# pidfile: /usr/local/memcached/memcached.pid  

# logfile: /usr/local/memcached/memcached_log.txt  

# memcached_home: /etc/memcached  

# chkconfig: 35 21 79  

# description: Start and stop memcached Service    

# Source function library  

. /etc/rc.d/init.d/functions    

RETVAL=0    

prog="memcached"  

basedir=/usr/local/memcached  

cmd=${basedir}/bin/memcached  

pidfile="$basedir/${prog}.pid"  

#logfile="$basedir/memcached_log.txt"    

# 设置memcached启动参数  

ipaddr="192.168.6.60"          # 绑定侦听的IP地址  

port="11211"                    # 服务端口  

username="root"               # 运行程序的用户身份  

max_memory=128              # default: 64M | 最大使用内存  

max_simul_conn=1024       # default: 1024 | 最大同时连接数  

#maxcon=51200  

#growth_factor=1.3           # default: 1.25 | 块大小增长因子  

#thread_num=6                # default: 4  

#verbose="-vv"                 # 查看详细启动信息  

#bind_protocol=binary      # ascii, binary, or auto (default)    

start() {  

echo -n $"Starting service: $prog"  

$cmd -d -m $max_memory -u $username -l $ipaddr -p $port -c $max_simul_conn -P $pidfile  

RETVAL=$?  

echo  

[ $RETVAL -eq 0 ] && touch /var/lock/subsys/$prog  

}    

stop() {  

echo -n $"Stopping service: $prog  "  

run_user=`whoami`  

pidlist=`ps -ef | grep $run_user | grep memcached | grep -v grep | awk ‘{print($2)}‘`  

for pid in $pidlist  

do  

# echo "pid=$pid"  

kill -9 $pid  

if [ $? -ne 0 ]; then  

return 1  

fi  

done  

RETVAL=$?  

echo  

[ $RETVAL -eq 0 ] && rm -f /var/lock/subsys/$prog  

}  

# See how we were called.  

case "$1" in  

start)  

start  

;;  

stop)  

stop  

;;  

#reload)  

#    reload  

#    ;;  

restart)  

stop  

start  

;;  

#condrestart)  

#    if [ -f /var/lock/subsys/$prog ]; then  

#        stop  

#        start  

#    fi  

#    ;;  

status)  

status memcached  

;;  

*)  

echo "Usage: $0 {start|stop|restart|status}"  

exit 1  

esac  

exit $RETVAL  

4.设置脚本可被执行：

# chmod +x memcached  

# chkconfig --add memcached  

# chkconfig --level 35 memcached on  

5.设置防火墙 

vi /etc/sysconfig/iptables  

将下面这行加入进去 

-A RH-Firewall-l-INPUT -p tcp -m tcp --dport 11211 -j ACCEPT  

注：将memcached加入到防火墙允许访问规则中 

service iptables restart  

注：防火墙重启 

6.启动memcached 

# service memcached start  

//启动的时候实际上是调用了下面的这个命令，以守护进程的方式来启动memcached 

/usr/local/memcached/bin/memcached -d -m 64 -u root -l 192.168.1.101  

-p 11211 -c 1024 -P /usr/local/memcached/memcached.pid  

7.查看memcached是否启动： 

# ps -ef | grep memcached
