Mac下安装Nginx及使用

Mac 安装 Nginx 及配置

1. 更新 Homebrew

   brew update
   

2. 下载并安装 Nginx

   brew install nginx
   

3. 查看 nginx 配置信息

   tong@MacBook-Pro ~ % brew info nginx
   
   版本信息
   ==> nginx: stable 1.25.1 (bottled), HEAD
   HTTP(S) server and reverse proxy, and IMAP/POP3 proxy server
   https://nginx.org/
   
   Nginx安装目录
   /opt/homebrew/Cellar/nginx/1.25.1 (26 files, 2.4MB) *
   Poured from bottle using the formulae.brew.sh API on 2023-06-17 at 15:52:25
   
   安装来源

   ==> Dependencies
   Required: openssl@1.1 ✔, pcre2 ✔
   ==> Options

   根目录
   ==> Caveats
   Docroot is: /opt/homebrew/var/www
   
   
   重点！！！nginx 的配置文件及默认启动端口 8080
   The default port has been set in /opt/homebrew/etc/nginx/nginx.conf to 8080 so that
   nginx can run without sudo.
   
   Nginx将在 Server 目录下加载所有文件，在这个
   nginx will load all files in /opt/homebrew/etc/nginx/servers/.
   
   To start nginx now and restart at login:
   brew services start nginx
   Or, if you don't want/need a background service you can just run:
   /opt/homebrew/opt/nginx/bin/nginx -g daemon off;
   ==> Analytics
   install: 81,387 (30 days), 151,458 (90 days), 151,458 (365 days)

   build-error: 0 (30 days)
   

4. Nginx常用命令

   启动
   brew services start nginx
   
   停止
   brew services stop nginx
   
   终端进入nginx 目录
   cd /opt/homebrew/etc/nginx
   
   编辑 nginx.conf 配置文件
   vim nginx.conf 
   
   编辑完成后:wq保存退出
   
   重新加载配置文件
   nginx -s reload
   

5. Nginx配置文件nginx.conf

   全局配置
   
   events {
       worker_connections  1024;
   }
   
   
   http {
   
       http 配置
       
       #原本没有，自己手动添加
       upstream XX{
       	//负载均衡配置
       }
       
       #主要配置 server，配自己需要的信息
       server {
           listen       8070;
           server_name  localhost;
   
          
           location / {        		
               root   html;
               index  index.html index.htm;
               proxy_pass http://localhost:8080;
           }
   
           error_page   500 502 503 504  /50x.html;
           location = /50x.html {
               root   html;
           }
   
       }
   
   
   
   		//原注释，现在释放生效
       # HTTPS server
       
       server {
           listen       443 ssl;
           server_name  localhost;
   				
   		#证书 cert.pen和 cert.key换成证书的目录
           ssl_certificate      cert.pem;
           ssl_certificate_key  cert.key;
   
           ssl_session_cache    shared:SSL:1m;
           ssl_session_timeout  5m;
   
           ssl_ciphers  HIGH:!aNULL:!MD5;
           ssl_prefer_server_ciphers  on;
   
           location / {
               root   html;
               index  index.html index.htm;
           }
       }
       include servers/*;
   }
   
   

   配置文件主要是配置 server 里面的内容，需要理解反向代理的概念，在编辑 nginx.conf时建议备份，防止修改错误，注意添加的代码均要是 ； 结尾。
