centos安装memcached

一、基础环境配置

#yum -y install gcc gcc-c++

二、安装libevent

#cd /usr/local

下载

#wget https://github.com/libevent/libevent/releases/download/release-2.1.8-stable/libevent-2.1.8-stable.tar.gz

解压

#tar -zxvf libevent-2.1.8-stable.tar.gz

#cd libevent-2.1.8-stable

编译

#./configure --prefix=/usr

安装

#make

#make install

三、安装memcached

#cd /usr/local

下载

#wget http://memcached.org/files/memcached-1.4.36.tar.gz

解压

#tar -zxvf memcached-1.4.36.tar.gz

#cd memcached-1.4.36

编译

#./configure -with-libevent=/usr/local/libevent-2.1.8-stable/ -prefix=/usr/local/memcached-1.4.36

安装

#make

#make install

启动

#/usr/local/memcached-1.4.36/bin/memcached -d -m 500m -p 11211 -u root

PS:附上一个memcached的启动shell脚本，命名为startup.sh

#!/bin/shecho "Start to start memcached server $(date)..."    MEMCACHED=/usr/local/memcached-1.4.36/bin/memcached    usage()  {       echo "usage: `basename $0` port"  }    if [ -n "$1" ]  then  {       pid=`ps aux|grep memcached|grep "$1" |grep -v grep|awk '{print $2}'`       if [ -n "$pid" ]       then       {            sleep 2            echo "kill memcached which port is $1 begin"            echo "pid:$pid"            kill -9 $pid            echo "kill memcached which port is $1 end"            sleep 2       }       fi       echo "begin to start memcached in port $1"       LOG_FILE=/usr/local/memcached-1.4.36/log/memcached_$1.log       rm -f $LOG_FILE       $MEMCACHED -d -m 2048 -p $1 -u root -vv >> $LOG_FILE 2>&1       echo "start memcached end"       tail -f $LOG_FILE  }  else  {       usage       exit 1  }  fi

注意：使用此脚本先要获取目录权限

#chmod 777 -R /usr/local/memcached-1.4.36

#cd  /usr/local/memcached-1.4.36

注意要自己创建log目录，不然启动脚本报错

#mkdir log

#cd /usr/local/memcached-1.4.36/bin

#touch startup.sh

然后把上面的命令复制进去

#cd /usr/local/memcached-1.4.36/bin

启动memcached

#./startup.sh 11211

查看进程

#ps aux|grep memcached
