今天在网页上传图片到博客,结果提示:“无法将上传的文件移动至 /home/wwwroot/wp-content/uploads/2013/”,郁闷了,认为是权限问题,修改了文件,都改成了777的权限,但是还是不可以写入,图片无法上传。
索性,我查看了我的网站根目录文件夹的权限,显示是www ,www ,而用ps aux|grep nginx 显示的是nobody 的身份运行nginx的子程序,ps aux|grep php-fpm,显示的也是nobody。同时发现,我网站里的其他的文件和文件夹的权限却是root,root。这可能是因为我上次直接用root身份拷贝导致的,所以,无法用nobody的身份修改root的文件。
方法如下:
第一步:
先分别将nginx和php-fpm子程序的运行身份变成www,用户组group也变成www。
修改nginx.conf文件,将user nobody nobody;改成user www www;
运行命令:
service nginx restart //重启nginx
修改php-fpm.conf,将其中的
user = nobody group = nobody
改成:
user = www group =www
运行命令:service php-fpm reload //重启php-fpm
第二步:
修改所有文件夹和文件为www,www
#chown -R www:www /wwwroot
再次上传图片,提示成功上传了,问题解决了。
网上还有一些其他的方法,比如将图片修改成英文名,或者修改文件夹为777。其实很多情况下权限是777了,但是依旧不能上传,可以考虑是不是文件属主的问题。

You should care about DependencyInjection(DI) because it makes your code clearer and easier to maintain. 1) DI makes it more modular by decoupling classes, 2) improves the convenience of testing and code flexibility, 3) Use DI containers to manage complex dependencies, but pay attention to performance impact and circular dependencies, 4) The best practice is to rely on abstract interfaces to achieve loose coupling.

Select DependencyInjection (DI) for large applications, ServiceLocator is suitable for small projects or prototypes. 1) DI improves the testability and modularity of the code through constructor injection. 2) ServiceLocator obtains services through center registration, which is convenient but may lead to an increase in code coupling.

mPDF
mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
