使用标准包连接到带有 go 应用程序的 mysql 实例时遇到问题。这是我的连接字符串/日志
[13 Nov 16 13:53 +0000] [INFO] connecting to MySQL.. root:awsomepass@tcp(a-mysql-0:3340)/db?charset=utf8&parseTime=True&loc=Local
2016/11/13 13:53:25 dial tcp 10.108.1.35:3340: getsockopt: connection refused
我试过
GRANT ALL PRIVILEGES ON *.* TO 'root'@'%' WITH GRANT OPTION;
这是我建立连接的方式,只是基本的,仅使用字符串连接
db, err := sql.Open("mysql", "root:awsomepass@tcp(a-mysql-0:3340)/db?charset=utf8&parseTime=True&loc=Local")
if err != nil {
log.Fatal(err)
}
我可以 ping 服务,使用 mysql-client 从不同的 pod 连接到它。
# can connect without port for service
/ # mysql -u root -h a-mysql-0 -p
