1. 使用docker-compose部署nexus

1. docker-compose-nexus.yml

   version: "3"
   services:
     nexus:
       container_name: my-nexus
       image: sonatype/nexus3:3.67.1
       hostname: my-nexus
       network_mode: host
       ports:
         - 8081:8081
       deploy:
         resources:
           limits:
             cpus: '4'
             memory: 8192M
           reservations:
             cpus: '4'
             memory: 4096M
       healthcheck:
         test: ["CMD", "curl", "-f", "http://localhost:8081"]
         interval: 30s
         timeout: 10s
         retries: 3
       volumes:
         - "/data/nexus:/nexus-data"
         - "/etc/localtime:/etc/localtime"
       restart: always
       
   

2. 部署

   docker-compose -f docker-compose-nexus.yml up -d
   

3. 根据自己服务器IP地址，配置hosts

   vim /etc/hosts
   
   192.168.xxx.xxx my-nexus
   

4. 防火墙开放8081端口

   firewall-cmd --zone=public --add-port=8081/tcp --permanent
   firewall-cmd --reload
   

5. web访问

   http://192.168.xxx.xxx:8081

   用户名：admin

   容器创建会生成默认密码，在容器内的/nexus-data/admin.password中。由于做了数据卷映射。所以在宿主机/data/nexus中也能看到admin.password

   使用默认密码登录成功后，根据提示修改密码

2. 配置https访问

1. docker-compose-nginx.yml

   version: "3"
   services:
     nginx:
        restart: always
        image: nginx:1.26.2
        container_name: my-nginx
        hostname: my-nginx
        network_mode: host
        privileged: true
        volumes:
          - "/config/nginx/nginx.conf:/etc/nginx/nginx.conf"
          - "/config/nginx/conf.d:/etc/nginx/conf.d"
          - "/logs/nginx:/var/log/nginx"
          - "/data/nginx:/data/nginx"
   

2. ssl证书及配置文件

   • 自己生成ssl证书，放到指定目录

   • 配置文件

     server {
             listen    18081 ssl;
             server_name  localhost;
             ssl_certificate      /etc/nginx/conf.d/certs/server.crt;
             ssl_certificate_key  /etc/nginx/conf.d/certs/server.key;
             ssl_session_cache    shared:SSL:1m;
             ssl_session_timeout  5m;
             ssl_protocols TLSv1.2 TLSv1.3;
             ssl_ciphers ECDHE-ECDSA-AES256-GCM-SHA384:ECDHE-RSA-AES256-GCM-SHA384:ECDHE-ECDSA-CHACHA20-POLY1305:ECDHE-RSA-CHACHA20-POLY1305:ECDHE-ECDSA-AES128-GCM-SHA256:ECDHE-RSA-AES128-GCM-SHA256;
             ssl_prefer_server_ciphers  on;
     		server_tokens off;
     		add_header Strict-Transport-Security "max-age=3600; includeSubDomains";
             client_max_body_size 2000m;
             root html;
      	      charset 'utf-8';
     		
     		location / {
     			proxy_set_header    X-Forwarded-For $proxy_add_x_forwarded_for;
     			proxy_set_header    Host $http_host;
     			proxy_set_header   X-Forwarded-Proto https;  # 转发时使用https协议
     			server_name_in_redirect on;
     			proxy_pass      http://my-nexus:8081;
             }
     	
     }
     

3. 部署

   docker-compose -f docker-compose-nginx.yml up -d
   

4. 根据服务器IP，配置hosts

   vim /etc/hosts
   
   192.168.xxx.xxx my-nginx
   

5. 防火墙开放18081端口

   firewall-cmd --zone=public --add-port=18081/tcp --permanent
   firewall-cmd --reload
   

6. web访问

   https://192.168.xxx.xxx:18081
