Nginx配置

一、配置本机hosts文件

# 路径：
# Windows: C:\Windows\System32\drivers\etc\hosts
# Linux/macOS: /etc/hosts
# linux一键追加
cat <<EOF | sudo tee -a /etc/hosts
192.168.110.203  www.local.com
192.168.110.203  www.wiki.local.com
EOF
# 手动在hosts中添加如下两条记录：
192.168.110.203  www.local.com
192.168.110.203  www.wiki.local.com

#1. Nginx 重新载入配置文件命令：在大多数 Linux 系统（包括 CentOS）上，可以使用以下命令重新载入 Nginx 配置文件：

sudo nginx -s reload
#2. 刷新 DNS 缓存：

#CentOS：在 CentOS 上，刷新 DNS 缓存的命令取决于使用的 DNS 解析服务。如果是 systemd-resolved，可以使用以下命令：
sudo systemctl daemon-reload

sudo systemd-resolve --flush-caches

#如果是 nscd（名称服务缓存守护程序），可以使用：
sudo systemctl restart nscd

#Windows：在 Windows 上，刷新 DNS 缓存的命令是：
ipconfig /flushdns

二、检查端口占用情况

#windows
netstat -ano | findstr ":80.*LISTENING"
#如果存在可通过命令关闭
tasklist /FI "PID eq [出现的PID]"

#linux
ss -tlnup | grep 80
kill -9 pid

三、配置文件

    server {
        listen       8080;
        server_name  nginx.local.com;
        location / {
            root   html;
            index  index.html index.htm;
        }

        error_page   500 502 503 504  /50x.html;
        location = /50x.html {
            root   html;
        }
    }

	server {
		listen       8080;
		server_name  wiki.local.com;


		location / {
            root C:/Users/Administrator/Downloads/nginx-1.26.3/nginx-1.26.3/wiki;

            index  wiki.html wiki.htm;
        }
		

		# 错误页面配置
		error_page   500 502 503 504  /50x.html;
		location = /50x.html {
			root   html;
		}
	}

四、配置文件示例

[root@vision ~]# cat /docker-opt/web/labelerv3-web/docker-compose.yml
version: "3"
services:
    labeler-web:
        image: nginx
        container_name: labeler3-web
        ports:
            - "9583:9583"
        volumes:

            - /docker-opt/web/labelerv3-web/default.conf:/etc/nginx/conf.d/default.conf
            - /etc/localtime:/etc/localtime:ro
            - /docker-opt/web/labelerv3-web/certs:/etc/nginx/ssl
        restart: always
[root@vision ~]# cat /docker-opt/web/labelerv3-web/default.conf

    }

        location ^~/websocket/ {

    }


    #error_page  404              /404.html;

    # redirect server error pages to the static page /50x.html
    #
    error_page   500 502 503 504  /50x.html;
    location = /50x.html {
        root   /usr/share/nginx/html;
