centos安装memcached

1.编译安装Libevent

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

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="192.168.1.101"          # 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=64                   # 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
