在 CentOS 7 上
/etc/hosts127.0.0.1 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
/etc/nginx/sites-available/myappupstream 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;
}
将其链接到
/etc/nginx/sites-enabled/cd /etc/nginx/sites-enabled/
ln -s ../sites-available/myapp
重启nginx：
service nginx restart
然后尝试访问url：
curl 192.168.0.1
出现错误：
<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>
我删除了
index.html/usr/share/nginx/htmlNginx 错误日志
/var/log/nginx/error.log2017/07/25 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"
为什么访问的是默认的
/usr/share/nginx/html/myapp/etc/nginx/sites-enabled/真正的问题是，操作系统发行版本和软件包版本，使得软件不同。
注意：这是 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 上的包等其他版本略有不同。所以用法也不一样。
它的目录是：
/etc/nginx/nginx.conf
/etc/nginx/conf.d/
# Notice, there aren't these directories exist!
/etc/nginx/sites-available/
/etc/nginx/sites-enabled/
所以用法不同，以下是必要的！
首先，注释掉
/etc/nginx/nginx.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 {
# }
# }
其次，在
/etc/nginx/conf.d/# 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
default.conf/etc/nginx/conf.d/第三，检查语法并重启nginx：
nginx -t
service nginx restart
运行时
/home/deploy/myapp/publiccurl 192.168.0.1您得到的错误是说 nginx 无法访问 /usr/share/nginx/html/ 的索引文件夹，这是在 app.conf 中热 tryfile @app 指令时发生的。原因是默认情况下 nginx 关闭 autoindex ；这意味着如果您请求 / 路径，则 try_file 将不允许它。 看： 自动索引
在您的情况下，您需要添加自动索引；服务器中 try_file 指令之前的指令。
