i want to run jenkins behind nginx tried following step

      location /jenkins {
                rewrite ^/jenkins(.*) $1 break;
                proxy_set_header        Host $http_host;
                proxy_set_header        X-Real-IP $remote_addr;
                proxy_set_header        X-Forwarded-For $proxy_add_x_forwarded_for;
                proxy_set_header        X-Forwarded-Proto $scheme;
                proxy_set_header        X-Forwarded-Host $host;
                proxy_set_header        X-Forwarded-Server $http_host;

                proxy_pass http://localhost:8000/jenkins;
            }

with localhost:8000 and localhost:8000/jenkins tried both

JENKINS_ARGS="--webroot=/var/cache/$NAME/war --httpPort=$HTTP_PORT --prefix=$PREFIX --httpListenAddress=127.0.0.1"

jenkins port changed to 8000 ... but getting 500 server error

if i don't add this line "rewrite ^/jenkins(.*) $1 break;" then getting 404 server error

sudo netstat -tulpn --- saw there on 8000 program is running

i want "location /jenkins" not "location /"
