问题描述
谁能帮我修复我收到的以下错误消息?我终于在虚拟机上安装了 Symfony，它似乎工作正常，除了我偶尔会收到类似这样的消息:
Can anyone help me fix the below error message I'm getting? I've finally got Symfony installed on a VM and it seems to be working ok except for the fact that I'm getting occasional messages for things like this:
[1/2] ContextErrorException: Warning: SessionHandler::read(): open(/var/lib/php5/sess_d8qgvn11jdu8rfuo1f0njokc67, O_RDWR) failed: Permission denied (13)
从我从阅读中了解到的，我认为这是因为我在 linux 和网络服务器之间的所有者/权限不匹配，但我不知道这会如何发生(我只是这是事实，我真的不明白如何/为什么要防止将来犯同样的错误).
From what I've picked up from reading around, I'm thinking it's because I have a mismatch between the owner/permissions between linux and the webserver but I don't know how this would happen (I'm just taking this as fact and I don't really understand how/why to prevent making the same mistakes in the future).
每次我遇到这些错误时，我都会提交以下命令的组合来尝试解决问题，但我猜这不是解决问题的正确方法(括号中的文字是我的理解/猜测他们做什么):
Each time I've been getting one of these errors I'm submitting a mix of the below commands to try and fix the problem but I'm guessing it's not the right way to go about it (text in brackets is my understanding/guessing of what they do):
sudo chmod a+x 修改目录权限
sudo chmod -R 775 除了它设置权限 -R 递归地应用它
sudo chmod -R 775 <path>Similar to previous except that it SETS the permissions -R applies it recursively
sudo chown -R :www-data 更改目录/文件的所有者/组
sudo chown -R <usr>:www-data <path>Changes the owner/group of the directory/file
推荐答案
你可以看看 http://symfony.com/doc/current/book/installation.html 在设置权限"部分.它讨论了应用程序/日志和应用程序/缓存，但您可以对任何其他需要的文件夹执行相同操作
You can take a look at http://symfony.com/doc/current/book/installation.html on "Setting up Permissions" section. It talks about app/logs and app/cache, but you can do the same on any other folder you need
