must have one register DataBase alias named default

[s016374]

错误：
[root@408cb45436b1 opt]# /home/go/bin/webcron
[ORM]register db Ping default, dial tcp :3306: getsockopt: connection refused
must have one register DataBase alias named default

mysql -hX.X.X.X -uXXX -p 可以通

请问怎么解决？

环境：
Linux version 3.10.0-327.el7.x86_64 ([email protected]) (gcc version 4.8.3 20140911 (Red Hat 4.8.3-9) (GCC) ) #1 SMP Thu Nov 19 22:10:57 UTC 2015

时间长了，记不清当时是怎么解决的了，但应该还是配置写的不对导致的。
看了下现在的配置如下，正常工作，希望有帮助。
appname = webcron
httpport = 8000
runmode = dev
jobs.pool = 50
site.name = schedule_manager
db.host = 192.168.x.x
db.user = xxx
db.password = xxx
db.port = 3306
db.name = dataserver
db.prefix = t_
db.timezone = Asia/Shanghai
mail.queue_size = 100
mail.from = [email protected]
mail.host = smtp.example.com
mail.port = 25
mail.user = username
mail.password = your password

mysql配置确认没有问题，但是启动也报这个错误

./webcron 
[ORM]2017/11/15 06:38:14 register db Ping `default`, dial tcp :3306: getsockopt: connection refused
must have one register DataBase alias named `default`

有大佬解决这个问题吗？
./webcron
[ORM]2017/11/16 16:43:10 register db Ping default, Error 1045: Access denied for user ''@'127.0.0.1' (using password: NO)
must have one register DataBase alias named default

我的问题已经解决了，安装说明中少写了一步，需要go build编译产生启动文件，原来的启动文件是无法使用的，导致启动报这个错误

1.go get github.com/lisijie/webcron
2.cd /root/go/src/github.com/lisijie/webcron
   go build

github.com/lisijie/webcron/app/mail

app/mail/mail.go:38:6: undefined: beego.Error

请问go build 报这个错误是什么原因？

是由于mysql server 默认连接的是127.0.0.1，
如果是Ubuntu环境可以建议你修改 sudo vi /etc/mysql/mysql.conf.d/mysqld.cnf这个文件，
