启动高性能web服务器和反向代理服务器nginx失败

Question

更新 - 我收到了这些错误日志：

nginx: [emerg] unknown "request_url" variable
Aug 19 01:14:58 nginx[4890]: nginx: 
configuration file /etc/nginx/nginx.conf test failed

这是我的 nginx.conf 文件：

user www-data;
worker_processes auto;
pid /run/nginx.pid;
include /etc/nginx/modules-enabled/*.conf;

events {
    worker_connections 768;
    # multi_accept on;
}

http {

    # Basic Settings

    sendfile on;

    tcp_nodelay on;

    types_hash_max_size 2048;
    # server_tokens off;

    # server_names_hash_bucket_size 64;
    # server_name_in_redirect off;

    include /etc/nginx/mime.types;
    default_type application/octet-stream;

    # gzip_types text/plain text/css application/json application/javascript

错误的“请求网址”部分可能在我的启用站点/默认文件中靠近底部的位置块中：

server {
    listen 80 default_server;
    listen [::]:80 default_server;

    # SSL configuration
    #
    listen 443 ssl default_server;
    listen [::]:443 ssl default_server;
    server_name         www.domainname;
    ssl_certificate     /etc/nginx/ssl/server.crt;
    ssl_certificate_key /etc/nginx/ssl/server.key;
    ssl_protocols       TLSv1 TLSv1.1 TLSv1.2;
    ssl_ciphers         HIGH:!aNULL:!MD5;

    root /var/www/html;

    # Add index.php to the list if you are using PHP
    index index.html index.htm index.nginx-debian.html;

    server_name _;

    location / {
            # First attempt to serve request as file, then
            # as directory, then fall back to displaying a 404.
            try_files $uri $uri/ =404;

            return 301 https://www.hobyn.co$request_url;

原始问题 - 运行时启动高性能 Web 服务器和反向代理服务器失败：

sudo /etc/init.d/nginx restart

在对我的 /etc/nginx/sites-available/default 文件进行以下服务器块配置后重新启动 nginx。我的 Angular 应用程序正在 /var/www/html 中提供：

server {
    listen 80 default_server;
    listen [::]:80 default_server;

    # SSL configuration
    #
    listen 443 ssl default_server;
    listen [::]:443 ssl default_server;
    server_name         www.mydomainname;
    ssl_certificate     /etc/nginx/ssl/****.crt;
    ssl_certificate_key /etc/nginx/ssl/****.key;
    ssl_protocols       TLSv1 TLSv1.1 TLSv1.2;
    ssl_ciphers         HIGH:!aNULL:!MD5;


location / {
            # First attempt to serve request as file, then
            # as directory, then fall back to displaying a 404.
            try_files $uri $uri/ =404;

            return 301 https://www.mydomainname$request_url;
    }

我在这里修复了此配置的错误：

server {
    # SSL configuration
    #
    listen 443 ssl http2 default_server;
    listen [::]:443 ssl default_server;
    server_name domainname www.domainname;
    ssl on;
    ssl_certificate     /etc/nginx/ssl/server.crt;
    ssl_certificate_key /etc/nginx/ssl/server.key;
    ssl_protocols       TLSv1 TLSv1.1 TLSv1.2;
    ssl_ciphers         HIGH:!aNULL:!MD5;

    proxy_set_header X_FORWARDED_PROTO https;
    proxy_set_header  X-Forwarded-For $proxy_add_x_forwarded_for;
    proxy_set_header  Host $http_host;
    proxy_set_header  X-Url-Scheme $scheme;
    proxy_redirect    off;
    proxy_max_temp_file_size 0;
