[root@localhost ~]# vi /home/software/nexus/nexus-2.14.3-02/conf/nexus.properties

修改：
nexus-webapp-context-path=/nexus
为：
nexus-webapp-context-path=/

重启nexus服务。

nginx反向代理：

upstream nexus_server {
 server localhost:8083;
}

server {
 listen 80;
 server_name nexus.xxx.com;

 # individual nginx logs for this web vhost
 #access_log /var/log/nginx/crm-web/access.log;
 error_log /var/log/nginx/nexus.xxx.com_error.log;


 location / {
 proxy_pass http://nexus_server;
 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;
 }



}

这样访问nexus时访问http://nexus.xxx.com即可，不需要加http://nexus.xxx.com/nexus了
