我试图让我的Django网站完全移动到https （目前它只是http ）。 networking服务器是nginx（反向代理）和gunicorn。
但是，即使正确安装SSL，打开端口443并调整我的nginx虚拟主机文件，我无法连接到我的网站通过https://example.com （ http://example.com工作正常）。 有人可以指导我如何解决这个问题？
以下是详细信息：
在/etc/iptables/rules.v4 （我使用iptables-persistent软件包）中，我有这个代码片段：
# Acceptable TCP traffic -A TCP -p tcp --dport 22 -j ACCEPT -A TCP -p tcp --dport 80 -j ACCEPT -A TCP -p tcp --dport 443 -j ACCEPT
如果我写了sudo netstat -4plunt ，输出显示端口443正在监听：
Proto Recv-Q Send-Q Local Address Foreign Address State PID/Program name tcp 0 0 0.0.0.0:80 0.0.0.0:* LISTEN 18445/nginx tcp 0 0 0.0.0.0:22 0.0.0.0:* LISTEN 923/sshd tcp 0 0 127.0.0.1:5432 0.0.0.0:* LISTEN 719/postgres tcp 0 0 0.0.0.0:443 0.0.0.0:* LISTEN 18445/nginx
sites-enabled文件夹中的我的nginx虚拟主机文件包含以下代码：
server { listen 80; listen 443 ssl; server_name example.com www.example.com; ssl_certificate /etc/ssl/certs/ssl-bundle.crt; ssl_certificate_key /etc/ssl/private/myserver.key; ssl_protocols TLSv1 TLSv1.1 TLSv1.2; ssl_prefer_server_ciphers on; ssl_ciphers 'EECDH+AESGCM:EDH+AESGCM:AES256+EECDH:AES256+EDH'; charset utf-8; underscores_in_headers on; location = /favicon.ico { access_log off; log_not_found off; } location /static/ { root /home/myuser/myprojectfolder/myproject; } location /static/admin/ { root /home/myuser/.virtualenvs/myenv/local/lib/python2.7/site-packages/django/contrib/admin/static/; } location /status { stub_status on; allow 127.0.0.1; allow 40.114.247.165; deny all; } location / { proxy_pass_request_headers on; proxy_buffering on; proxy_buffers 8 24k; proxy_buffer_size 2k; include proxy_params; #include /etc/nginx/naxsi.rules; #include /etc/nginx/naxsi_whitelist.rules; proxy_pass http://unix:/home/myuser/myprojectfolder/myproject/myproject.sock; } error_page 500 502 503 504 /500.html; location = /500.html { root /home/myuser/myprojectfolder/myproject/templates/; } }
最后，我将下面一行添加到我的django项目的settings.py文件中：
SECURE_PROXY_SSL_HEADER = ('HTTP_X_FORWARDED_PROTO', 'https')
完成上述所有更改后，我仍然无法通过https运行我的网站; 连接总是超时。
有人可以帮我解决这个问题吗？ 如果您需要，请向我询问更多信息。
/etc/iptables/rules.v4完整规则集如下：
*filter # Allow all outgoing, but drop incoming and forwarding packets by default :INPUT DROP [0:0] :FORWARD DROP [0:0] :OUTPUT ACCEPT [0:0] # Custom per-protocol chains :UDP - [0:0] :TCP - [0:0] :ICMP - [0:0] # Acceptable UDP traffic # Acceptable TCP traffic -A TCP -p tcp --dport 22 -j ACCEPT -A TCP -p tcp --dport 80 -j ACCEPT -A TCP -p tcp --dport 443 -j ACCEPT # Acceptable ICMP traffic # Boilerplate acceptance policy -A INPUT -m conntrack --ctstate ESTABLISHED,RELATED -j ACCEPT -A INPUT -i lo -j ACCEPT # Drop invalid packets -A INPUT -m conntrack --ctstate INVALID -j DROP # Pass traffic to protocol-specific chains ## Only allow new connections (established and related should already be handled) ## For TCP, additionally only allow new SYN packets since that is the only valid ## method for establishing a new TCP connection -A INPUT -p udp -m conntrack --ctstate NEW -j UDP -A INPUT -p tcp --syn -m conntrack --ctstate NEW -j TCP -A INPUT -p icmp -m conntrack --ctstate NEW -j ICMP # Reject anything that's fallen through to this point ## Try to be protocol-specific w/ rejection message -A INPUT -p udp -j REJECT --reject-with icmp-port-unreachable -A INPUT -p tcp -j REJECT --reject-with tcp-reset -A INPUT -j REJECT --reject-with icmp-proto-unreachable # Commit the changes COMMIT *raw :PREROUTING ACCEPT [0:0] :OUTPUT ACCEPT [0:0] COMMIT *nat :PREROUTING ACCEPT [0:0] :INPUT ACCEPT [0:0] :OUTPUT ACCEPT [0:0] :POSTROUTING ACCEPT [0:0] COMMIT *security :INPUT ACCEPT [0:0] :FORWARD ACCEPT [0:0] :OUTPUT ACCEPT [0:0] COMMIT *mangle :PREROUTING ACCEPT [0:0] :INPUT ACCEPT [0:0] :FORWARD ACCEPT [0:0] :OUTPUT ACCEPT [0:0] :POSTROUTING ACCEPT [0:0] COMMIT
/proc/net/ip_tables_matches包含：
conntrack conntrack conntrack udplite udp tcp icmp
包含在我的nginx虚拟主机文件中的proxy_params包含以下内容：
proxy_set_header Host $host; proxy_set_header User-Agent $http_user_agent; proxy_set_header X-Real-IP $remote_addr; proxy_set_header Remote-Addr $remote_addr; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; proxy_set_header X-Forwarded-Proto $scheme;
连接可能会超时，因为你的iptables在某些时候可能不正确。
尝试冲洗你的Iptables（如果你有一些工作在那里先保存）。这些在冲洗testing后添加是很好的。
-A INPUT -p tcp --dport 80 -m state --state NEW -j ACCEPT -A INPUT -p tcp --dport 443 -m state --state NEW -j ACCEPT # Allow inbound traffic from established connections. # This includes ICMP error returns. -A INPUT -m state --state ESTABLISHED,RELATED -j ACCEPT
