在 Linux 上把跑在其它端口的 Node 服务通过 Nginx 反向代理出去。

概览
把跑在其它端口的 Node 服务通过 Nginx 反向代理出去,连同安装步骤一起记一下。
安装
需要的几个工具:
- Nginx
- Node
- forever
Node
curl -sL https://deb.nodesource.com/setup_9.x | sudo -E bash -
sudo apt-get install -y nodejs
Nginx
sudo apt-get install -y nginx
forever
sudo npm install -g forever
配置
先看一下 Nginx 的全局配置。
全局配置
cd /etc/nginx
cat nginx.conf
文件大致是这样:
2018-07-19 更新:把
client_max_body_size取消注释并调大,可以放宽上传文件的体积上限。
user www-data;
worker_processes auto;
pid /run/nginx.pid;
events {
worker_connections 768;
# multi_accept on;
}
http {
##
# Basic Settings
##
sendfile on;
tcp_nopush on;
tcp_nodelay on;
keepalive_timeout 65;
types_hash_max_size 2048;
server_tokens off; # 2019-03-05 更新:关掉它能藏住 nginx 版本号,安全性略增
# server_names_hash_bucket_size 64;
# server_name_in_redirect off;
include /etc/nginx/mime.types;
default_type application/octet-stream;
##
# SSL Settings
##
ssl_protocols TLSv1 TLSv1.1 TLSv1.2; # Dropping SSLv3, ref: POODLE
ssl_prefer_server_ciphers on;
##
# Logging Settings
##
access_log /var/log/nginx/access.log;
error_log /var/log/nginx/error.log;
##
# Gzip Settings
##
gzip on;
gzip_disable "msie6";
##
# Max POST upload size limit
##
# client_max_body_size 20m;
# gzip_vary on;
# gzip_proxied any;
# gzip_comp_level 6;
# gzip_buffers 16 8k;
# gzip_http_version 1.1;
# gzip_types text/plain text/css application/json application/javascript text/xml application/xml application/xml+rss text/javascript;
##
# Virtual Host Configs
##
include /etc/nginx/conf.d/*.conf; # <== 确认未被注释
include /etc/nginx/sites-enabled/*; # <== 确认未被注释
}
确认 include /etc/nginx/conf.d/*.conf; 和 include /etc/nginx/sites-enabled/*; 两行没被注释,被注释了就取消注释。
项目配置
进 /etc/nginx/conf.d,按习惯命名规则新建一个项目的配置文件。下面以给 champion-gg-bot 加官网 cgb.mipha.io 为例,Node 服务监听 8081:
cd /etc/nginx/conf.d
sudo nano cgb_mipha_io_8081.conf
文件内容:
upstream cgbmiphaio { # 应用名
server 127.0.0.1:8081; # node 监听的端口
keepalive 64;
}
server {
listen 80; # 80 是 http,443 是 https
server_name xxx.xxx.xxx.xxx cgb.mipha.io; # 多个域名空格分隔
location / {
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header Host $http_host;
proxy_set_header X-Nginx-Proxy true;
proxy_set_header Connection "";
proxy_pass http://cgbmiphaio; # 上面定义的应用名
}
}
保存后 Nginx 不会自动加载,先校验配置再 reload:
sudo nginx -t
sudo service nginx reload
# 或第一次启动
sudo service nginx start
运行项目
build 完后,用 forever 把进程托管在后台:
forever start dist/index.js
查看 / 停止:
forever list
forever stop dist/index.js
forever stopall
