memcache 安装 （windows和linux）

---

windows 64bit 环境下安装

下载 memcache 安装包 ：http://pan.baidu.com/s/1pLcjTzl

解压到d盘任意位置 , cmd(以管理员身份运行，否则安装失败) 执行命令

没有报错说明我们已经安装成功

下载 php_memcache.dll : https://pecl.php.net/package/memcache/3.0.8/windows

我的是5.6的版本 所以下载 64位 TS版本

将dll扩展放入php扩展文件夹中

在php.ini 中添加 extension=php_memcache.dll

然后重启wampserver
注意：apache文件夹中的php.ini 是用于浏览器访问 php文件夹中的php.ini 是适用于命令行运行php脚本

php测试代码 (我的是命令行测试)

linux 安装 （centos 64bit）

安装环境说明：

操作系统：Centos 6.5 -64bit
安装路径：/usr/local/memcached

---

安装编译需要的扩展包

yum install libevent libevent-devel

---

下载memcached tgz包 到home文件夹

[root@localhost home]# wget http://memcached.org/files/memcached-1.4.25.tar.gz

---

解压并编译memcached

tar zxvf memcached-1.4.25.tar.gz

• 打开文件夹 指定安装路径 并编译

  cd memcached-1.4.25

  ./configure --prefix=/usr/local/memcached

  make && make install

---

安装PHP memcache 扩展包

• 下载php memcache 扩展 tgz包

  [root@localhost home]# wget https://pecl.php.net/get/memcache-3.0.8.tgz
  [root@localhost home]# tar zxf memcache-3.0.8.tgz
  [root@localhost home]# cd memcache-3.0.8
  [root@localhost memcache-3.0.8]# /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/

---

修改 php.ini 文件

#php.ini 中的 extension_dir =” ./”  
#修改为extension_dir = “/usr/local/php/lib/php/extensions/no-debug-non-zts-20131226/” 
(若已经修改过请忽略)

#添加 
extension=memcache.so

#重启 php-fpm 
/etc/init.d/php-fpm restart

---

安装PHP memcached 扩展包

• 下载libevent tgz包 并安装
  官网：http://libevent.org/

  [root@localhost home]# tar zxf libevent-2.0.21-stable.tar.gz
  [root@localhost home]# cd libevent-2.0.21-stable
  [root@localhost home]# ./configure --prefix=/usr/local/libevent/
  [root@localhost libevent-2.0.21-stable]# make && make install

• 重新编译安装memcached服务，并配置libevent

  [root@localhost home]# cd memcached-1.4.25
  [root@localhost memcached-1.4.25]# ./configure --prefix=/usr/local/memcache/ --with-libevent=/usr/local/libevent/
  [root@localhost memcached-1.4.25]# make && make install

• 下载 libmemcached tgz包 并编译安装

  安装SASL相关环境
  yum install cyrus-sasl-plain cyrus-sasl  cyrus-sasl-devel  cyrus-sasl-lib 
  
  官网：http://libmemcached.org/libMemcached.html
  [root@localhost home]# wget https://launchpadlibrarian.net/165454254/libmemcached-1.0.18.tar.gz
  [root@localhost home]# tar zxf libmemcached-1.0.18.tar.gz
  [root@localhost home]# cd libmemcached-1.0.18
  [root@localhost libmemcached-1.0.18]# ./configure --prefix=/usr/local/libmemcached  --with-memcached --enable-sasl
  [root@localhost libmemcached-1.0.18] make
  [root@localhost libmemcached-1.0.18] make install
  

• 下载php memcached 扩展 tgz包

  [root@localhost home]# wget https://pecl.php.net/get/memcached-2.2.0.tgz
  [root@localhost home]# tar zxf memcached-2.2.0.tgz
  [root@localhost home]# cd memcached-2.2.0
  [root@localhost memcached-2.2.0]# /usr/local/php/bin/phpize

  

    ./configure --with-php-config=/usr/local/php/bin/php-config 
    --with-libmemcached-dir=/usr/local/libmemcached  --enable-memcached-sasl（注意这个参数）

如果提示下面错误信息 说明我们要安装 libsasl2-dev    

yum直接搜索是没有对应的package的 我们用笨方法
[root@localhost home]# yum search sasl |  grep  dev
[root@localhost home]# yum install cyrus-sasl-devel 

• 继续编译

  ./configure --with-php-config=/usr/local/php/bin/php-config 
  --with-libmemcached-dir=/usr/local/libmemcached  --enable-memcached-sasl（注意这个参数）
   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/

修改 php.ini 文件

#php.ini 中的 extension_dir =” ./”  
#修改为extension_dir = “/usr/local/php/lib/php/extensions/no-debug-non-zts-20131226/” 
(若已经修改过请忽略)

#添加 
extension=memcached.so

#重启 php-fpm 
/etc/init.d/php-fpm restart

---

创建memcached自启动脚本 , 在 /etc/init.d/中新建文件 memcached

[root@localhost init.d]# touch memcached
[root@localhost init.d]# chmod 777 memcached

复制粘贴以下内容于 redis文件 保存退出

• 配置开启自启动

  chkconfig --add memcached

• 增加开启启动设置启动级别

  chkconfig --level 2345 memcached on

• 测试启动，停止，重启memcached

  # 服务启动，停止service memcached start service memcached stop
  # init.d目录启动，停止/etc/init.d/memcached start/etc/init.d/memcached stop

Memcache 防火墙配置

# 打开防火墙规则vim /etc/sysconfig/iptables

# 增加内容 -A INPUT -p tcp -m tcp --dport 11211 -j ACCEPT   




# 重启火墙规则立即生效service iptables restart

$memcached->addServer('192.168.206.128',11211);
$memcached->set('key','TK');
echo $memcached->get('key'); // TK
