如何检查nginx gzip_static模块是否正常工作? [英] How can I check that the nginx gzip_static module is working?

问题描述

如何检查nginx是否正在提供.gz版本的静态文件(如果存在)?

How can I check that nginx is serving the .gz version of static files, if they exist?

我使用gzip静态模块编译了nginx，但是我的日志中未提及.gz版本. (我将global.js和global.css文件缩小了，并将它们的.gz版本放在同一目录中.)

I compiled nginx with the gzip static module, but I don't see any mention of the .gz version being served in my logs. (I have minified global.js and global.css files with .gz versions of them in the same directory).

nginx.conf的相关部分如下所示:

The relevant part of nginx.conf looks like this:

gzip  on;
gzip_static on;
gzip_http_version 1.0;
gzip_disable "MSIE [1-6]\.";
gzip_vary on;

gzip_comp_level 2;
gzip_proxied any;
gzip_types text/plain text/html text/css application/x-javascript text/xml application/xml application/xml+rss text/javascript;

任何指针将不胜感激.

推荐答案

使用strace.首先，您需要检测nginx进程的PID:

Use strace. First, you need to detect PID of nginx process:

# ps ax | grep nginx
25043 ?        Ss     0:00 nginx: master process /usr/sbin/nginx -c /etc/nginx/nginx.conf
25044 ?        S      0:02 nginx: worker process

好，所以25044是工作进程.现在，我们对其进行跟踪:

Ok, so 25044 is the worker process. Now, we trace it:

# strace -p 25044 2>&1 | grep gz
open("/var/www/css/ymax.css.gz", O_RDONLY|O_NONBLOCK) = 438
open("/var/www/css/patches/patch_my_layout.css.gz", O_RDONLY|O_NONBLOCK) = -1 ENOENT (No such file or directory)
open("/var/www/yaml/core/iehacks.css.gz", O_RDONLY|O_NONBLOCK) = -1 ENOENT (No such file or directory)
open("/var/www/js/koznazna5.js.gz", O_RDONLY|O_NONBLOCK) = -1 ENOENT (No such file or directory)
open("/var/www/css/ymax.css.gz", O_RDONLY|O_NONBLOCK) = 216

如您所见，它正在尝试查找.gz版本的文件.

As you can see, it is trying to find .gz versions of files.
