grafana默认监听3000端口，检查端口状态。

$ netstat -nlpt | grep 3000
(Not all processes could be identified, non-owned process info
 will not be shown, you would have to be root to see it all.)

如果出现启动错误，比如下面的错误：

可以去/var/log/grafana/grafana.log查看具体的启动日志。

默认启动后的admin账号和密码是admin和admin，第一次进入之后会要求修改账号密码。

配置nginx

配置nginx通过80端口转发到3000端口，同时还要转发websocket请求。

server {
        listen 80;
        server_name     grafana.domain.com;
        location / {
                proxy_set_header Host $http_host;
                proxy_pass http://localhost:3000/;
                proxy_set_header X-Real-IP $remote_addr;
                proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        }
        location /api/live/ws {
                rewrite  ^/(.*)  /$1 break;
                proxy_http_version 1.1;
                proxy_set_header Upgrade $http_upgrade;
                proxy_set_header Connection "Upgrade";
                proxy_set_header Host $http_host;
                proxy_pass http://localhost:3000/;
  }
}

这里一定要设置proxy_set_header Host $http_host;这个header，不然会出现访问错误。
