Grafana设置匿名登录

将配置文件中的auth.anonymous的enabled设置为true就可以匿名登录，不用输入用户名和密码

#################################### Anonymous Auth ##########################
[auth.anonymous]
# enable anonymous access
;enabled = false

# specify organization name that should be used for anonymous users
;org_name = Main Org.

# Specify role for anonymous users. Defaults to Viewer, other valid options are Editor and Admin
;org_role = Viewer

org_role设置为Viewer时只能进行查看。
