Nginx adds https certificate reverse proxy nexus

After the ip is bound to the domain name, apply for the https certificate and put the certificate under nginx. The configuration of nginx is as follows

upstream nexus-server{
    
    
    server 127.0.0.1:8081;
}

server {
    
    
    listen 80;
    server_name xx.xx;
    location / {
    
    
        return 301 https://xx.xx;
    }

    location ~ /.well-known {
    
    
        root /tmp;
    }
}

server {
    
    
    listen 443 ssl;
    server_name  localhost;
    
    ssl_certificate      /etc/nginx/server.crt;
    ssl_certificate_key  /etc/nginx/server.key;
    ssl_session_timeout  5m;
    client_max_body_size     50m; #文件大小限制，默认1m

    location /nexus {
    
    
        proxy_set_header Host $host;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header X-Forwarded-Proto "https";
        proxy_pass http://nexus-server/nexus;
    }
    
    location /repository {
    
    
        proxy_set_header Host $host;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header X-Forwarded-Proto "https";
        proxy_pass http://nexus-server/nexus/repository/maven-public/;
    }
}

Note: The value of location must be equal to the context at the time of creation. For example: when creating location /nexus: NEXUS_CONTEXT=nexus
