PHP会话未保存在内存缓存中 [英] PHP sessions not being saved in memcache
问题描述
使用Amazon Linux在AWS上运行应用程序。
Running an application using php 5.4 on AWS using the Amazon Linux.
PHP版本是PHP 5.4.28。
从AWS repo安装的memcache lib是php54-pecl-memcache-3.0.8-1.11.amzn1.x86_64
PHP version is PHP 5.4.28. memcache lib installed from the AWS repo is php54-pecl-memcache-3.0.8-1.11.amzn1.x86_64
我已经验证php正在使用/ etc / php.ini：
I have verified that php is using /etc/php.ini:
[root@ip-xx.xx.xx.xx]# php -i | grep Config
Configuration File (php.ini) Path => /etc
Loaded Configuration File => /etc/php.ini
设置显示我应该使用memcache：
The setting show that I should be using memcache:
[root@ip-10-40-17-119 etc]# grep "^session.save" php.ini
session.save_handler="memcache"
session.save_path="tcp://<elasticache-endpoint>:11211"
[root@ip-10-40-17-119 php.d]# php -i | grep session.save
session.save_handler => memcache => memcache
session.save_path => tcp://<elasicache-endpoint>:11211?persistent=1&weight=1&timeout=1&retry_interval=15 => tcp://<elasticache-endpoint>:11211?persistent=1&weight=1&timeout=1&retry_interval=15
我可以telnet从框到结束点&端口并正确连接，因此实例能够连接到memcached服务器。
I can telnet from the box to the end point & port and connect properly, so the instance is able to connect to the memcached server.
我们尝试的东西：
- 我删除了tcp：
- 我们已经从session.save_handler =memcache更改为session.save_handler = memcached
- 每次我们进行更改时，我们停止httpd服务器，然后再次启动
- 我们甚至尝试重新启动服务器
- I have removed the tcp:// from the php.ini file, and that made no difference - sessions are still getting saved in files.
- We have changed from session.save_handler="memcache" to session.save_handler="memcached"
- each time we make a change, we stop the httpd server, and then start it again
- we have even tried rebooting the servers
无论我们尝试了什么，会话都存储在/ var / lib / php / sessions。
有没有什么我缺少，或者是已知的5.4或AWS问题？
Regardless of what we've tried, sessions are stored on disk to /var/lib/php/sessions. Is there something I'm missing, or is this a known 5.4 or AWS issue?
推荐答案
设法找出问题。
首先，我们创建了一个简单的页面，发出phpinfo（）。注意，你通过web服务器运行这是很重要的 - 运行php -i不包括apache可能添加的任何覆盖。
First, we created a simple page that spit out phpinfo(). Note that it is important that you run this thru the web server - running php -i DOES NOT include any overrides that apache may add.
在会话部分下，输出列出所有指令，以及本地值和主值。
Under the session section, the output lists all the directives, and a "Local Value" and a "Master Value".
本地值具有：
session.save_handler files
session.save_path /var/lib/php/session
而主值具有：
session.save_handler memcache
session.save_path tcp://<endpoint>:11211
事实证明，在/etc/httpd/conf.d/php.conf中指定文件。这似乎是一个Redhat / CentOS / Fedora的事情。
It turns out that there's an override installed by default in /etc/httpd/conf.d/php.conf that specifies the files. This appears to be a Redhat/CentOS/Fedora thing.
从php.conf中删除这些值修复了问题。
Removing those values from php.conf fixed the problem.
