apisix version :2.8:
OS (cmd: Linux 3.10.0-1160.6.1.el7.x86_64 #1 SMP Tue Nov 17 13:59:11 UTC 2020 x86_64 x86_64 x86_64 GNU/Linux):
etcd version:3.4:

My config.yaml body:

`apisix:
enable_admin: true
port_admin: 9180
allow_admin:
- 0.0.0.0/0
https_admin: false
admin_key:
- name: "admin"
key: edd1c9dxe2s5f136f87ad84dd25s8f1
role: admin

allow_admin:
https_admin: false

nginx_config:
error_log_level: warn

etcd:
host:
- "http://10.0.1.6:2379"`
