详解nginx如何配置HTTPS

# 1、首先，进入你想创建证书和私钥的目录，例如：
cd /etc/nginx/

# 2、创建服务器私钥，命令会让你输入一个口令：
openssl genrsa -des3 -out server.key 1024

# 3、创建签名请求的证书（CSR）：
openssl req -new -key server.key -out server.csr

# 4、在加载SSL支持的Nginx并使用上述私钥时除去必须的口令：
cp server.key server.key.org
openssl rsa -in server.key.org -out server.key


# 5、最后标记证书使用上述私钥和CSR：
openssl x509 -req -days 365 -in server.csr -signkey server.key -out server.crt

cd /etc/nginx
vim nginx.conf
#
# HTTPS server configuration
#
server {
  listen    443;
  server_name 本机的IP地址;

  ssl         on;
  ssl_certificate   /etc/nginx/server.crt;
  ssl_certificate_key /etc/nginx/server.key;

  ssl_session_timeout 5m;

#  ssl_protocols SSLv2 SSLv3 TLSv1;
#  ssl_ciphers ALL:!ADH:!EXPORT56:RC4+RSA:+HIGH:+MEDIUM:+LOW:+SSLv2:+EXP;
#  ssl_prefer_server_ciphers  on;

  location / {
    #root  html;
    #index testssl.html index.html index.htm;
   proxy_redirect off;
   proxy_set_header Host $host;
   proxy_set_header X-Real-IP $remote_addr;
   proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
   proxy_pass http://IP地址/ssl/;
  }
}

location ~ /services/.*$ {
    if ($server_port ~ "^80$"){
      set $rule_0 1$rule_0;
    }
    if ($rule_0 = "1"){
      rewrite /(.*) https://IP地址/$1 permanent;            break;
    }
  }

/usr/local/nginx/sbin/nginx -t
nginx: the configuration file /usr/local/nginx/conf/nginx.conf syntax is ok 
nginx: configuration file /usr/local/nginx/conf/nginx.conf test is successful (显示表示配置文件没有错误)

service nginx reload (重新加载nginx服务) 
netstat -lan | grep 443 (查看443端口) 
tcp 0 0 0.0.0.0:443 0.0.0.0:* LISTEN (有看到这一行 就表示HTTPS已经在工作了)
