[common]
bind_port       = 8
tcp_mux         = 8
dashboard_port  = 8
dashboard_user  = 8
dashboard_pwd   = 8
token           = 8
vhost_http_port = 8
bind_addr       = 0.0.0.0
max_pool_count  = 8
kcp_bind_port   = 8
subdomain_host  = 8

格式有误 = 号前方的空格问题
应为

bind_port = 8
tcp_mux = 8
dashboard_port = 8
dashboard_user = 8
dashboard_pwd = 8
token = 8
vhost_http_port = 8
bind_addr = 8
max_pool_count = 8
kcp_bind_port = 8
subdomain_host = 8

问题2.可否升级为新版 谢谢
