“Memcache 无法连接，连接被拒绝 (111)”？

首先...

我必须说，我对服务器了解不多。我是那种不经常使用命令行的 php 开发人员。我对终端很不习惯。

不过，我正在学习。我不习惯将我的网站放在没有托管主机的专用服务器上。但现在我第一次拥有它，我需要自己安装 Memcache。

一些服务器信息

  • 产品：Media Temple 上的专用服务器 (DV)
  • Parallels® Plesk Panel 12 或 cPanel® 11
  • CentOS 5.7（最终版本）
  • Apache 2.2
  • PHP 5.4
  • YUM 包管理

我做了什么

我已遵循以下指南：https://mediatemple.net/community/products/dv/204644340/installing-pecl-extensions

但当然是用memcache而不是uploadprogress。

我已经检查过，Memcache 已安装并正在运行。并且$memcache = new Memcache;在我的 php 代码中运行正常。但是$memcache->connect('localhost', 11211);它不起作用。我收到错误消息：

Warning: Memcache::connect(): Can't connect to localhost:11211, Connection refused (111) in /var/www/vhosts/[mydomain]/httpdocs/index.php on line 10 Could not connect to memcache server

我曾尝试更改localhost服务器的 IP 号码，但没有成功。

我之前在 Google 上搜索了很多，最后找到了关于安装的文章和论坛帖子Memcached。所以我按照其中一个指南尝试安装它。但收到错误消息，No package memcached available.因此无法安装。

以下是我之后执行的命令示例：

Nothing to do
[root@mydomain /]# php -i | grep memcache
PHP Warning:  Module 'memcache' already loaded in Unknown on line 0
/etc/php.d/memcached.ini,
PHP Warning:  Unknown: It is not safe to rely on the system's timezone settings. You are *required* to use the date.timezone setting or the date_default_timezone_set() function. In case you used any of those methods and you are still getting this warning, you most likely misspelled the timezone identifier. We selected 'America/Los_Angeles' for 'PDT/-7.0/DST' instead in Unknown on line 0

Disabled

所以...

我忘记做什么了？

答案1

更新！

所以我最终成功了。方法如下：

  1. 在 Google 上搜索“查看 memcached 是否已在命令行 centos5 中安装”
  2. 点击第三个结果，最终进入此页面：http://cnedelcu.blogspot.se/2009/09/setting-up-and-using-memcached-memcache.html
  3. 按照步骤操作

  4. 成功安装Memcached，但无法安装Memcache：

    [root@mydomain /]# yum install php-pecl-memcache
Loaded plugins: fastestmirror, priorities

 You could try using --skip-broken to work around the problem
 You could try running: package-cleanup --problems
                        package-cleanup --dupes
                        rpm -Va --nofiles --nodigest
The program package-cleanup is found in the yum-utils package.

但是，似乎并不需要成功。Memcache 似乎现在可以正常工作了！
