Grafana / Server Error

报错原因

grafana更换数据库grafana.db（var/lib/grafana/下）后登陆报错(Sadly something went wrong Server ErrorCheck the Grafana server logs for the detailed error message.)
找到日志(var/log/grafana/grafana.log)得知t=2021-07-20T14:38:04+0800 lvl=eror msg=“failed to create auth token” logger=http.server error=“attempt to write a readonly database”
原来是更换数据库后数据库是只读的，文件需要更改权限

解决方法

/var/lib/grafana$ chmod 777 grafana.db
