Centos6.2安装Memcached详细教程

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  

    #!/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 

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

service iptables restart 

6.启动memcached

service memcached start  

7.查看memcached是否启动：

ps -ef | grep memcached  

8.memcached命令参数解释
