nginx - 禁用 http 到 https 重定向？

Question

我按照本教程http://www.schenkels.nl/2014/12/reverse-proxy-with-odoo-8-nginx-ubuntu-14-04-lts/ 如何使用 nginx 为 odoo 制作反向代理。

这里一切顺利。但问题出在证书上。 每个浏览器都发誓我的自签名证书不受信任。这是测试服务器，所以我现在并不关心安全性。我尝试使用证书和 ssl 禁用/评论所有内容。但是nginx仍然重定向到https，然后当它没有找到证书时，它只会给出这个错误：

Unable to make a secure connection to the server. This may be a problem with the server, or it may be requiring a client authentication certificate that you don't have

但是我怎样才能忽略https，而使用http而不进行任何加密呢？我需要在 nginx 内部进行一些调整吗？

例如使用apache，如果没有指定使用安全连接，那么它只是使用普通的http，就是这样。希望其他人对 nginx 有更好的体验。

我调整的配置看起来像这样（我只是评论了一些部分并将rewrite更改为http而不是https）：

upstream odoo8 {
server 127.0.0.1:8069 weight=1 fail_timeout=0;
}

upstream odoo8-im {
server 127.0.0.1:8072 weight=1 fail_timeout=0;
}

## http redirects to https ##
server {
listen 80;
server_name _;

# Strict Transport Security
add_header Strict-Transport-Security max-age=2592000;
rewrite ^/.*$ http://$host$request_uri? permanent;
}

server {
# server port and name
listen 443;
server_name _;

# Specifies the maximum accepted body size of a client request,
# as indicated by the request header Content-Length.
client_max_body_size 200m;

# add ssl specific settings
#keepalive_timeout 60;
ssl off;
#ssl_certificate /etc/ssl/nginx/server.crt;
#ssl_certificate_key /etc/ssl/nginx/server.key;

# limit ciphers
#ssl_ciphers HIGH:!ADH:!MD5;
#ssl_protocols SSLv3 TLSv1;
#ssl_prefer_server_ciphers on;

# increase proxy buffer to handle some OpenERP web requests
proxy_buffers 16 64k;
proxy_buffer_size 128k;

#general proxy settings
# force timeouts if the backend dies
proxy_connect_timeout 600s;
proxy_send_timeout 600s;
proxy_read_timeout 600s;
proxy_next_upstream error timeout invalid_header http_500 http_502 http_503;

# set headers
proxy_set_header Host $host;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forward-For $proxy_add_x_forwarded_for;

# Let the OpenERP web service know that we’re using HTTPS, otherwise
# it will generate URL using http:// and not https://
#proxy_set_header X-Forwarded-Proto https;

# by default, do not forward anything
proxy_redirect off;
proxy_buffering off;

location / {
proxy_pass http://odoo8;
}

location /longpolling {
proxy_pass http://odoo8-im;
}

# cache some static data in memory for 60mins.
# under heavy load this should relieve stress on the OpenERP web interface a bit.
location /web/static/ {
proxy_cache_valid 200 60m;
proxy_buffering on;
expires 864000;
proxy_pass http://odoo8;
}
}

你只需要注释掉 80 端口上的重定向并监听 80 端口。 这可以通过配置中的以下更新来完成

upstream odoo8 {
server 127.0.0.1:8069 weight=1 fail_timeout=0;
}

upstream odoo8-im {
server 127.0.0.1:8072 weight=1 fail_timeout=0;
}

## http redirects to https ##
#server {
#listen 80;
#server_name _;

# Strict Transport Security
#add_header Strict-Transport-Security max-age=2592000;
#rewrite ^/.*$ http://$host$request_uri? permanent;
#}

server {
# server port and name
# listen 443;  # comment out this line
listen 80;
server_name _;

# Specifies the maximum accepted body size of a client request,
# as indicated by the request header Content-Length.
client_max_body_size 200m;

# add ssl specific settings
#keepalive_timeout 60;
ssl off;
#ssl_certificate /etc/ssl/nginx/server.crt;
#ssl_certificate_key /etc/ssl/nginx/server.key;

# limit ciphers
#ssl_ciphers HIGH:!ADH:!MD5;
#ssl_protocols SSLv3 TLSv1;
#ssl_prefer_server_ciphers on;

# increase proxy buffer to handle some OpenERP web requests
proxy_buffers 16 64k;
proxy_buffer_size 128k;

#general proxy settings
# force timeouts if the backend dies
proxy_connect_timeout 600s;
proxy_send_timeout 600s;
proxy_read_timeout 600s;
proxy_next_upstream error timeout invalid_header http_500 http_502 http_503;

# set headers
proxy_set_header Host $host;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forward-For $proxy_add_x_forwarded_for;

# Let the OpenERP web service know that we’re using HTTPS, otherwise
# it will generate URL using http:// and not https://
#proxy_set_header X-Forwarded-Proto https;

# by default, do not forward anything
proxy_redirect off;
proxy_buffering off;

location / {
proxy_pass http://odoo8;
}

location /longpolling {
proxy_pass http://odoo8-im;
}

# cache some static data in memory for 60mins.
