部署

官方的下载地址：https://grafana.com/grafana/download 

  1. wget https://dl.grafana.com/enterprise/release/grafana-enterprise-8.1.3-1.x86_64.rpm
  2. sudo yum install grafana-enterprise-8.1.3-1.x86_64.rpm
  3. systemctl restart grafana-server.service

配置参考：

  1. [paths]
  2. logs = /var/log/grafana
  4. [server]
  5. protocol = http
  6. http_addr = 0.0.0.0 
  7. http_port = 80 
  8. domain = grafana.dev.ops.com

协议

http, https,h2或socket

http_地址

要绑定到的 IP 地址。如果为空将绑定到所有接口

http_port

要绑定到的端口，默认为3000。要使用端口 80，您需要授予 Grafana 二进制权限，例如：
$ sudo setcap ‘cap_net_bind_service=+ep’ /usr/sbin/grafana-server

或者使用以下命令将端口 80 重定向到 Grafana 端口：
$ sudo iptables -t nat -A PREROUTING -p tcp —dport 80 -j REDIRECT —to-port 3000

另一种方法是在 Grafana 前面放置一个像 Nginx 或 Apache 这样的 Web 服务器，并让它们代理对 Grafana 的请求。
sudo setcap ‘cap_net_bind_service=+ep’ /usr/sbin/grafana-server
