Centos6.7 下编译安装Memcache

安装环境说明：

操作系统：Centos 6.7 -64bit
软件版本：memcached-1.4.33、memcache-2.2.7、libevent-2.0.22
安装路径：/usr/local/libevent /usr/local/memcached

开始编译libevent

方式一：
yum install libevent-devel
方式二：编译安装
tar -zxxf libevent-2.0.22-stable.tar.gz
 ./configure --prefix=/usr/local/libevent
 make && make install
echo "/usr/local/libevent/lib" > /etc/ld.so.conf.d/libevent.conf
ldconfig 

开始编译memcached

tar -zxvf memcached-1.4.33.tar.gz 
cd memcached-1.4.33
./configure --prefix=/usr/local/memcached --with-libevent=/usr/local/libevent
make && make install

创建memcached自启动脚本

#! /bin/sh
#
# chkconfig: - 55 45
# description:  The memcached daemon is a network memory cache service.
# processname: memcached
# config: /etc/sysconfig/memcached

# Source function library - for other linux
. /etc/rc.d/init.d/functions
# Source function library - for suse linux
#. /lib/lsb/init-functions

ip="192.168.10.100"             # 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_connection=1024             # default: 1024 | 最大同时连接数

if [ -f /etc/sysconfig/memcached ];then
  . /etc/sysconfig/memcached
fi

# Check that networking is up.
if [ "$NETWORKING" = "no" ]
then
  exit 0
fi

RETVAL=0

basedir=/usr/local/memcached
cmd=${basedir}/bin/memcached

start () {
  echo -n $"Starting service：$prog "
  chown $username $basedir
  $cmd -d -p $port -u $username  -m $max_memory -c $max_connection -P $pidfile $OPTIONS
  RETVAL=$?
  echo
  [ $RETVAL -eq 0 ] && touch /var/lock/subsys/memcached
  return $retval
}

stop() {
    echo -n $"Stopping service: $prog  "
    current_user=$(whoami)
    pidlist=$(ps -ef | grep $current_user | grep memcached | grep -v grep | awk '{print $2}')
    for pid in $pidlist ; do
        kill -9 $pid
        if [ $? -ne 0 ]; then
           return 1
        fi
    done
    RETVAL=$?
    echo
    [ $RETVAL -eq 0 ] && rm -f /var/lock/subsys/memcached
}

restart () {
  stop
  start
}

# See how we were called.
case "$1" in
  start)
  start
  ;;
  stop)
  stop
  ;;
  status)
  status memcached
  ;;
  restart|reload)
  restart
  ;;
  condrestart)
  [ -f /var/lock/subsys/memcached ] && restart || :
  ;;
  *)
  echo $"Usage: $0 {start|stop|status|restart|reload|condrestart}"
  exit 1
esac

exit $?

脚本配置

#将此脚本cp到/etc/init.d目录下并改名为memcached,然后增加执行权限
cp memcached /etc/init.d/memcached
chmod a+x /etc/init.d/memcached

配置开启自启动

chkconfig --add memcached              # 增加开启启动
chkconfig --level 2345 memcached on    # 设置启动级别
#测试启动，停止，重启memcached
service memcached start
service memcached stop

安装PHP memcache 扩展包

tar -zxvf memcache-2.2.7.tgz
cd memcache-2.2.7
/usr/local/php/bin/phpize
./configure --with-php-config=/usr/local/php/bin/php-config 
make 
make install

#安装成功后会输出这个地址，这是php扩展模块文件夹
/usr/local/php/lib/php/extensions/no-debug-non-zts-20131226

配置PHP支持memcached

vim /etc/php.ini 
#编辑php.ini文件增加以下内容
extension_dir = "/usr/local/php/lib/php/extensions/no-debug-non-zts-20131226"
extension = memcache.so
#重新启动php-fpm
/etc/init.d/php-fpm restart

在php测试下是否成功

<?php
echo "www.jcwtime.cn<br/>\n";

$mem = new Memcache;
$mem->connect("192.168.10.101", 11211)  or die("Could not connect");

$version = $mem->getVersion();
echo "Server's version: ".$version."<br/>\n";

$mem->set('key', 'Hello World', 0, 600) or die("Failed to save data at the memcached server");
echo "Store data in the cache (data will expire in 600 seconds)<br/>\n";

$get_result = $mem->get('key');
echo "$get_result is from memcached server.";         
?>

成功输出了缓存截图：
