本来使用“爱洞特漏”的方法安装Memcache，结果安装结束后memcached一直启动不了。
后来使用yum的方法才搞定，特此把安装过程贴出来，来帮助和我遇到一样问题的朋友： 第一步安装 memcache php 扩展 ---------------------------------------------------------------------------------------------- 1、依次运行如下命令： #wget http://pecl.php.net/get/memcache-2.2.6.tgz; #tar zxvf memcache-2.2.6.tgz; #cd memcache-2.2.6; #/usr/local/php/bin/phpize; #./configure --with-php-config=/usr/local/php/bin/php-config; #make; #make install; 2、显示如下信息时为安装成功: Installing shared extensions: /usr/local/php/lib/php/extensions/no-debug-non-zts-20090626/ 3、修改php配置文件，载入memcache #vi /etc/php.ini 在最后加上下面的代码 [memcache] extension_dir = "/usr/local/php/lib/php/extensions/no-debug-non-zts-20090626/" extension = "memcache.so" 4、刷新PHP配置 #killall php-fpm #/usr/local/php/sbin/php-fpm 查看phpinfo中是否有memcache一项,有则成功 (如果安装完网站提示出现502 只需要进面板 HOST界面 点击php运行即可) ---------------------------------------------------------------------------------------------- 第二步安装 memcached ---------------------------------------------------------------------------------------------- 1、安装memcached #yum -y install memcached 2、启动进程 #memcached -d -u root -m 128 -l 127.0.0.1 -p 12121 -c 256 -P /tmp/memcached.pid （说明：创建一个128MB，只允许本机 127.0.0.1 连接，端口号是 12121,并发数是 256） 3、添加开机启动进程， #vi /etc/rc.d/rc.local 加入 memcached -d -u root -m 128 -l 127.0.0.1 -p 12121 -c 256 -P /tmp/memcached.pid 备注：如果要结束Memcache进程: #pkill memcached ---------------------------------------------------------------------------------------------- OK，到这里结束了。 最后再问一个小问题：我使用eAccelerator来加速PHP。并且想用它来缓存数据库，但是使用eaccelerator_put却提示：“Fatal error: Call to undefined function eaccelerator_put()”。请问是什么问题？  点赞，加油！ (1分)

Call to undefined function eaccelerator_put()
应该不支持吧， 只看到有 引用: [1219] => eaccelerator_caching [1220] => eaccelerator_clear [1221] => eaccelerator_clean [1222] => eaccelerator_info [1223] => eaccelerator_purge [1224] => eaccelerator_cached_scripts [1225] => eaccelerator_removed_scripts [1226] => eaccelerator_check_mtime [1227] => eaccelerator_optimizer 这些函数， 要用自定义缓存，还是用别的缓存扩展。
