linux centos5.8 安装memcached

1.安装libevent
yum install libevent.x86_64 libevent-devel.x86_64
没有libevent编译memcached为出错

checking for libevent directory… configure: error: libevent is required. You can get it from http://www.monkey.org/~provos/libevent/
If it’s already installed, specify its path using –with-libevent=/dir/

2.安装memcached

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=/opt/memcached-1.4.15
make
make install

ln -s /opt/memcached-1.4.15 /opt/memcached

3.配置文件
vi /opt/memcached/my.conf

PORT=”11200″
IP=”192.168.0.40″
USER=”root”
MAXCONN=”1524″
CACHESIZE=”3000″
OPTIONS=””
#memcached

4.启动/关闭脚本
vi /etc/init.d/memcached

#!/bin/bash
#
# Save me to /etc/init.d/memcached
# And add me to system start
# chmod +x memcached
# chkconfig –add memcached
# chkconfig –level 35 memcached on
#
# Written by lei
#
# chkconfig: – 80 12
# description: Distributed memory caching daemon
#
# processname: memcached
# config: /usr/local/memcached/my.conf

source /etc/rc.d/init.d/functions

### Default variables
PORT=”11211″
IP=”192.168.0.40″
USER=”root”
MAXCONN=”1524″
CACHESIZE=”64″
OPTIONS=””
SYSCONFIG=”/opt/memcached/my.conf”

### Read configuration
[ -r “$SYSCONFIG” ] && source “$SYSCONFIG”

RETVAL=0
prog=”/opt/memcached/bin/memcached”
desc=”Distributed memory caching”

start() {
echo -n $”Starting $desc ($prog): ”
daemon $prog -d -p $PORT -l $IP -u $USER -c $MAXCONN -m $CACHESIZE $OPTIONS
RETVAL=$?
echo
[ $RETVAL -eq 0 ] && touch /var/lock/subsys/memcached
return $RETVAL
}

stop() {
echo -n $”Shutting down $desc ($prog): ”
killproc $prog
RETVAL=$?
echo
[ $RETVAL -eq 0 ] && rm -f /var/lock/subsys/memcached
return $RETVAL
}

restart() {
stop
start
}

reload() {
echo -n $”Reloading $desc ($prog): ”
killproc $prog -HUP
RETVAL=$?
echo
return $RETVAL
}

case “$1″ in

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

esac

exit $RETVAL

5.添加iptables 充许192.168.0.0/24访问

iptables -A INPUT -s 192.168.0.0/255.255.255.0 -p tcp -m tcp –dport 11200 -j ACCEPT

6.启动
/etc/init.d/memcached start
