我编写了一个系统，该系统可自动在Microsoft Azure上部署VM，在其上安装Sql Server，然后针对新安装的服务器执行resource "aws_alb" "bluegreen_balancer" {

脚本以初始化环境。在星期五，这一切都按预期进行。今天，我遇到了这个错误。
我的代码具有以下相关导入：
.sql，并在安装数据库后使用以下代码实际连接到数据库（为简便起见删除了错误处理）：
import(
"database/sql"
_ "github.com/denisenkom/go-mssqldb"
)
在// variables
connectionString := "sqlserver://MasterUser:MasterPassword@xx.xx.xx.xxx:1433"
dbName := "mssql"
dbFile := "mssql.sql"
// open database / get metadata sorted
db, err := sql.Open(dbname, connectionString)
defer db.Close()
//Check to see if the connection is successful.
err = db.Ping() // <--------
// file input
fileBytes, err := ioutil.ReadFile("../sql/" + dbsql)
fileReader := bytes.NewReader(fileBytes)
// parse line-by-line
scanner := bufio.NewScanner(fileReader)
lineNo := 0
for scanner.Scan() {
toExec := scanner.Text()
lineNo += 1
_, err = db.Exec(toExec) // <--------
}
和每个db.Ping()上均发生错误。在这些情况下，与db.Exec()关联的消息是
err对于服务器本身，我使用以下脚本通过SSH进行安装：
TLS Handshake failed: Cannot read handshake packet: EOF
否则，这似乎可以很好地工作-我通过SSH手动连接到实例没有问题，并且脚本退出没有错误。我不确定它的相关性。
我尝试通过SSH自己进入服务器并在本地打开sql服务器控制台，这导致出现以下错误消息：
# install mssql server
sudo wget -qO- https://packages.microsoft.com/keys/microsoft.asc | sudo apt-key add -
sudo add-apt-repository "$(wget -qO- https://packages.microsoft.com/config/ubuntu/16.04/mssql-server-2017.list)"
curl https://packages.microsoft.com/config/ubuntu/16.04/prod.list | sudo tee /etc/apt/sources.list.d/msprod.list
sudo apt-get -y update
sudo apt-get -y install mssql-server
# configure MSSQL
sudo /opt/mssql/bin/mssql-conf setup
# install local tools
sudo ACCEPT_EULA=y apt-get -y install mssql-tools
# do basic initialization in advance of .sql script
/opt/mssql-tools/bin/sqlcmd -S localhost -U SA -P ${MasterPassword} -Q "CREATE LOGIN ${MasterUser} WITH PASSWORD = '${MasterPassword}';"
/opt/mssql-tools/bin/sqlcmd -S localhost -U SA -P ${MasterPassword} -Q "CREATE USER ${MasterUser} FOR LOGIN ${MasterUser};"
/opt/mssql-tools/bin/sqlcmd -S localhost -U SA -P ${MasterPassword} -Q "ALTER SERVER ROLE sysadmin ADD MEMBER ${MasterUser};"
这可能是相关的，但我不知道如何。
这是什么原因导致的，如何解决？是我的代码中，我创建的充当服务器的VM上的错误还是两者之间？我如何最好地解决该问题？
答案 0 :(得分：0)
我最终解决了这个问题，但没有找到根本原因。尝试通过SSH连接到VM并在本地访问数据库后，遇到以下错误：
Sqlcmd: Error: Microsoft ODBC Driver 17 for SQL Server : TCP Provider: Error code 0x2746.
Sqlcmd: Error: Microsoft ODBC Driver 17 for SQL Server : Client unable to establish connection.
对这些问题的关注导致我进入this GitHub issue，从而解决了我的问题。看来是版本问题-在我的安装脚本中，我替换了
sudo apt-get -y install mssql-server
使用
sudo apt-get -y install mssql-server=14.0.3192.2-2
问题消失了。
