Question

我正在尝试编写一个Ruby脚本来杀死我的localhost上的数据库服务器。

当我运行'ant hsql'时，它启动数据库（下面的输出），我必须保持该终端窗口打开。构建文件：/Users/cparaiso/dev/src/testproject-src/build.xml

hsql:

install-parent-pom:
[artifact:install] [INFO] Installing /Users/cparaiso/dev/src/testproject-src/pom.xml to /Users/cparaiso/.m2/repository/org/jasig/portal/uportal-parent/4.0.3/uportal-parent-4.0.3.pom

     [java] [Server@6f507fb2]: To close normally, connect and execute SHUTDOWN SQL
     [java] [Server@6f507fb2]: From command line, use [Ctrl]+[C] to abort abruptly

我的问题是如何在Ruby中不使用kill命令来关闭服务器以终止进程？

如果我尝试通过kill命令终止进程，我会'BUILD FAILED'并且它会一直卡住，直到我按Ctrl + C.这不是我想要的。有任何想法吗？ TIA

我不知道如何在Ruby中发出SQL语句，但如果连接到数据库服务器并发出SQL语句SHUTDOWN，它将关闭服务器进程。

通过Ruby连接到HSQL并关闭服务器
