一、grafana修改配置

在root_url后边添加路径/grafana（该路径可自定义，和nginx配置中保持一致即可）
vim /etc/grafana/default.ini
# 后缀与nginx代理后缀保持一致
root_url = %(protocol)s://%(domain)s:%(http_port)s/grafana
# 允许跨域
allowed_origins = *
# 允许iframe嵌入
allow_embedding = true

二、NGINX配置

# 代理Grafana
server{
        listen 80;
        server_name 10.0.52.222;
        charset utf-8;

        location /grafana {
        root   html;
        index  index.html index.htm;
        add_header 'Access-Control-Allow-Origin' '*';
        add_header Access-Control-Allow-Methods GET,POST,OPTIONS,DELETE;
        add_header 'Access-Control-Allow-Headers' 'userId,DNT,X-CustomHeader,Keep-Alive,User-Agent,X-Requested-With,If-Modified-Since,Cache-Control,Content-Type';
        proxy_pass http://127.0.0.1:3000;
        rewrite ^/grafana/(.*) /$1 break;
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header   Host $host;
        # websocket处理
        proxy_http_version 1.1;
        proxy_set_header Upgrade $http_upgrade;
        proxy_set_header Connection "upgrade";
        # 处理grafana重定向问题， proxy_redict grafana默认路径 nginx代理路径
        proxy_redirect http://localhost:3000 http://10.0.52.222:80;
        }
}
