我正在尝试将Grails 2.5.5应用程序部署到Tomcat 7(在Ubuntu服务器上运行)。我在Intellij 14中使用了war -stacktrace -verbose命令来创建war文件。在我的target目录中，它成功创建了war文件，我们将其称为myapp-0.1.war。然后在终端(我正在使用Linux Mint)中，我使用以下命令将其复制到服务器上(在下面的示例中，我的详细信息替换为mypcusername，myserverusername和123.123.123.123)
rsync -rtvW --delete /home/mypcusername/NetbeansProjects/myapp/target/myapp-0.1.war/ myserverusername@123.123.123.123:/home/myserverusername/myapp-0.1.war/
也不必担心上述命令的
NetbeansProjects部分，它最初是一个Netbeans项目。然后，我先使用sudo cp -a myapp-0.1.war/ /var/lib/tomcat7/webapps/，再使用sudo rm -R ROOT删除原始的ROOT目录。然后我运行了sudo service tomcat7 restart，这就是问题所在。日志给了我以下内容:Sep 03, 2017 10:23:39 AM org.apache.coyote.AbstractProtocol pause

编辑，由于suricatta，我按照他的指示创建并整理了所有使所有这些警告都消失的目录。我正在更新日志。
自从最初提出这个问题以来，我意识到我从未真正将.war文件复制到我的服务器，因为当我尝试提取文件时，它会告诉我诸如“您无法提取目录”之类的内容，然后我注意到它创建了一个每次我使用
rsync -rtvW --delete /home/mypcusername/NetbeansProjects/myapp/target/myapp-0.1.war/ myserverusername@123.123.123.123:/home/myserverusername/myapp-0.1.war/时，都会创建一个名为myapp-0.1.war的空目录。然后，我使用了
scp /home/mypcusername/NetBeansProjects/myapp/target/myapp-0.1.war myserverusername@41.185.91.194:/home/myserverusername，它确实将 war 复制到了我的服务器上。这次在/ var / lib / tomcat7 / webapps / ROOT中提取了实际文件后，我重新启动了Tomcat，然后得到了上面的日志。当我转到123.123.123.123:8080时，出现空白页面，并显示javascript错误，显示GET http://123.123.123.123:8080/ 404 (Not Found)，并尝试了不同的变体，例如<ip>:8080/myapp和<ip>:8080/myapp/home，均得到了相同的结果。我 checkout 了this答案，但这似乎不适用于我，因为我的applicationContext.xml中的值与该问题的OP没有相同。让我知道是否需要发布我的applicationContext.xml。
最佳答案
我开始了一个新项目，将我要部署的项目中的所有内容复制到新项目中并进行了部署，这解决了我遇到的问题。
