PHP: 安装 - Manual

安装

安装此 PECL 扩展相关的信息可在手册中标题为 PECL 扩展的安装章节中找到。更多信息如新的发行版本、下载、源文件、维护人员信息及变更日志等，都在此处： » https://pecl.php.net/package/memcached.

如果 libmemcached 被安装在一个非标准路径，使用 --with-libmemcached-dir=DIR 来指定路径，DIR 就是 libmemcached 安装时的 prefix 参数。这个路径需要包含文件 include/libmemcached/memcached.h。

如果要支持压缩就需要 zlib。对于非标准安装的 zlib 库，使用 --with-zlib-dir=DIR 来指定 zlib 安装路径，DIR 就是 zib 安装时的 prefix 参数。

session 处理程序的支持默认是开启的。如果要关闭它，使用选项 --disable-memcached-session。

默认情况下禁用 SASL 身份验证支持。要启用，请使用 --enable-memcached-sasl。这要求已安装 libsasl2，并且已在启用 SASL 支持的情况下构建 libmemcached。

Do not lose your time to install it on Ubuntu just trying "sudo apt-get install php5-memcached". There is something you need to do that sure installing memcached. Anyway...



Step 1.

$ sudo apt-get install memcached

Step 2.

$ sudo apt-get install php5-memcached

Step 3.

$ sudo /etc/init.d/apache2 restart



Ready!



What about some test?



<?php

error_reporting(E_ALL & ~E_NOTICE);



$mc = new Memcached();

$mc->addServer("localhost", 11211);



$mc->set("foo", "Hello!");

$mc->set("bar", "Memcached...");



$arr = array(

    $mc->get("foo"),

    $mc->get("bar")

);

var_dump($arr);

?>



Hoping to help someone.

For PHP 7 seems to work:

    $ sudo apt-get install memcached
    $ sudo apt-get install php-memcached
    $ sudo apachectl graceful

## php 7.2.19 / ubuntu 18.04.1

$mc = new Memcached();
$mc->addServer("localhost", 11211);
...

If your server has --enable-json=shared as mine did, this extension requires you to have extension=json.so to load properly.

i'm planning on using membase for my website and i was really struggling to install the memcashed php client on ubuntu with pear, but actually there is an easier way:

$ sudo apt-get install php5-memcached

you dont even need to install the membase server first - this can be done afterwards. hope this helps someone!

At present memcached-1.0.0 does not compile with libmemcached-0.38. This is apparently due to libmemcached chaning the API.

For evidence, see this bug: http://pecl.php.net/bugs/bug.php?id=17070

Note: I am encountering the same 'memcached_st' has no member named 'hash' error on a Debian lenny amd_64 box.
