Question

在CentOS 7上

/etc/hosts：

127.0.0.1   localhost localhost.localdomain localhost4 localhost4.localdomain4
::1         localhost localhost.localdomain localhost6 localhost6.localdomain6

192.168.0.1  app1

从包中安装Nginx：

yum install nginx

在/etc/nginx/nginx.conf：

# ...
include /etc/nginx/conf.d/*.conf;

server {
    listen       80 default_server;
    listen       [::]:80 default_server;
    server_name  _;
    root         /usr/share/nginx/html;

    # Load configuration files for the default server block.
    include /etc/nginx/default.d/*.conf;

    location / {
    }

    error_page 404 /404.html;
        location = /40x.html {
    }

    error_page 500 502 503 504 /50x.html;
        location = /50x.html {
    }
}
# ...

在名为/etc/nginx/sites-available/的{{1}}下创建了一个新文件：

myapp

将其链接到upstream app { # Path to Unicorn SOCK file, as defined previously server unix:///home/deploy/myapp/tmp/sockets/unicorn.sock; } server { listen 192.168.0.1:80; server_name app1; # Application root, as defined previously root /home/deploy/myapp/public; try_files $uri/index.html $uri @app; location @app { proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; proxy_set_header Host $http_host; proxy_redirect off; proxy_pass http://app; } error_page 500 502 503 504 /500.html; client_max_body_size 4G; keepalive_timeout 10; }：

/etc/nginx/sites-enabled/

重新启动nginx：

cd /etc/nginx/sites-enabled/
ln -s ../sites-available/myapp

然后尝试访问url：

service nginx restart

收到错误：

curl 192.168.0.1

我删除了<html> <head><title>403 Forbidden</title></head> <body bgcolor="white"> <center><h1>403 Forbidden</h1></center> <hr><center>nginx/1.10.2</center> </body> </html>路径下的默认index.html文件，因此获得了403 Forbidden。

Nginx错误日志/usr/share/nginx/html：

/var/log/nginx/error.log

为什么它会在2017/07/25 03:35:59 [error] 8200#0: *1 directory index of "/usr/share/nginx/html/" is forbidden, client: 192.168.0.2, server: _, request: "GET / HTTP/1.1", host: "192.168.0.1"目录下访问默认/usr/share/nginx/html/路径，而不是新添加的myapp？

Answer 1

你得到的错误是说nginx无法访问/ usr / share / nginx / html /的索引文件夹，当它在app.conf中运行tryfile @app指令时会发生这种情况。是默认情况下nginx有autoindex off;这意味着如果您请求/ path，它将不允许在try_file上。看到： autoindex

在您的情况下，您需要添加自动索引;在try_file指令之前的服务器中的指令。

Answer 2

真正的问题是，操作系统分发版本和软件包版本使软件不同。

注意：它是CentOS 7.3！

我用来安装nginx的方法是：

yum update
yum install epel-release
yum install nginx

然后，nginx版本可能与Ubuntu上的其他版本有点不同。所以用法也不一样。

其目录是：

/etc/nginx/nginx.conf
/etc/nginx/conf.d/
# Notice, there aren't these directories exist!
/etc/nginx/sites-available/
/etc/nginx/sites-enabled/

因此用法不同，以下是必要的！

首先，命令/etc/nginx/nginx.conf中的默认设置：

#    server {
#        listen       80 default_server;
#        listen       [::]:80 default_server;
#        server_name  _;
#        root         /usr/share/nginx/html;
#
#        # Load configuration files for the default server block.
#        include /etc/nginx/default.d/*.conf;
#
#        location / {
#        }
#
#        error_page 404 /404.html;
#            location = /40x.html {
#        }
#
#        error_page 500 502 503 504 /50x.html;
#            location = /50x.html {
#        }
#   }

其次，在/etc/nginx/conf.d/下为应用程序创建新配置：

# File Name: rails.conf
upstream app {
    # Path to Unicorn SOCK file, as defined previously
    server unix:/home/deploy/myapp/tmp/sockets/unicorn.sock fail_timeout=0;
}

server {
    listen 192.168.0.1:80;
    server_name app1;

    # Application root, as defined previously
    root /home/deploy/myapp/public;

    try_files $uri/index.html $uri @app;

    location @app {
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_set_header Host $http_host;
        proxy_redirect off;
        proxy_set_header X-FORWARDED_PROTO https;
        proxy_pass http://app;
    }

    error_page 500 502 503 504 /500.html;
    client_max_body_size 4G;
    keepalive_timeout 10;
  }

如果在default.conf下存在/etc/nginx/conf.d/，请将其删除。

第三，检查语法并重启nginx：

nginx -t
service nginx restart

运行/home/deploy/myapp/public时，它将访问指向curl 192.168.0.1的路径。

如何在CentOS 7上禁用403时正确设置Nginx？
