How do you know if Tomcat Server is installed on your PC
提问by CodeNinja
I am using Windows 7 OS. I just installed jaspersoft server which installed Apache Tomcat and mysql as a bundle along with it.
我正在使用 Windows 7 操作系统。我刚刚安装了 jaspersoft 服务器，它安装了 Apache Tomcat 和 mysql 作为一个捆绑包。
I go to http://localhost:8080and theres a message that says webpage is not available.
我去 http://localhost:8080，那里有一条消息，说网页不可用。
I am a beginner, and I would like to know if Tomcat is first installed on my computer. Can you tell me how I can do that ? ( I would also like to know if it has to be started and on what port it was installed.)
我是初学者，我想知道我的电脑上是否先安装了Tomcat。你能告诉我怎么做吗？（我还想知道它是否必须启动以及安装在哪个端口上。）

Heres something I did . i am really confused now . I found the location of the tomcat server. I found the server.xml file. The port in the server.xml file was listed as 8005. I also found start.bat which I ran. I now see that http://localhost:8080works but http://localhost:8005doesnt . Would you know why ?? The port 8005 should work because thats what was listed in the server.xml
这是我做的。我现在真的很困惑。我找到了tomcat服务器的位置。我找到了 server.xml 文件。server.xml 文件中的端口被列为 8005。我还找到了我运行的 start.bat。我现在看到这http://localhost:8080有效，但http://localhost:8005没有。你知道为什么吗？？端口 8005 应该可以工作，因为这是 server.xml 中列出的

The port 8005 is used as service port. You can send a shutdown command (a configurable password)to that port. It will not "speak" HTTP, so you cannot use your browser to connect.
端口 8005 用作服务端口。您可以向该端口发送关闭命令（可配置的密码）。它不会“说”HTTP，因此您无法使用浏览器进行连接。
The default port for delivering web-content is 8080.
用于传送 Web 内容的默认端口是 8080。
But there may be other applications listen to that port. So your tomcat may not start, if the port is not available.
但是可能有其他应用程序侦听该端口。因此，如果端口不可用，您的 tomcat 可能无法启动。
You asked "How do you know, if tomcat server is installed on your PC?". The answer to that question is: You can't
您问“您怎么知道您的 PC 上是否安装了 tomcat 服务器？”。这个问题的答案是：你不能
You can't determine, if it is installed, because it may be only extracted from a ZIP archive or packaged within another application (Like JBoss AS (I think)).
您无法确定它是否已安装，因为它可能只能从 ZIP 存档中提取或打包在另一个应用程序中（例如 JBoss AS（我认为））。

In order to make
为了要做
http://localhost:8080
work, tomcat has to be started first. You can check server.xml file in conf folder for the port information. You can search if tomcat is installed on your machine. Just go to start and then type tomcat. If it is installed it will give you the directory where it is installed. Then you can select that path and run it from command prompt. Example if tomcat is installed in C:\Programfile\tomcat. You need to set this path in command prompt,go to bin folder and startup. Example: C:\Programfile\tomcat\bin\startup. Else you can also run it by directly going to the path and run startup batch file.
工作，必须先启动tomcat。您可以检查 conf 文件夹中的 server.xml 文件以获取端口信息。您可以搜索您的机器上是否安装了 tomcat。只需转到开始，然后键入 tomcat。如果已安装，它将为您提供安装目录。然后您可以选择该路径并从命令提示符运行它。例如，如果 tomcat 安装在 C:\Programfile\tomcat 中。您需要在命令提示符中设置此路径，转到 bin 文件夹并启动。示例：C:\Programfile\tomcat\bin\startup。否则，您也可以直接转到路径并运行启动批处理文件来运行它。

In case of Windows(in my case XP):-
如果是 Windows（在我的情况下是 XP）：-
- Check the directory where tomcat is installed.
- Open the directory called \conf in it.
- Then search file server.xml
- Open that file and check what is the connector port for HTTP,whre you will found something like 8009,8080 etc.
- Suppose it found 8009,use that port as "/localhost:8009/" in your web-browser with HTTP protocol. Hope this will work !
- 检查tomcat的安装目录。
- 在其中打开名为 \conf 的目录。
- 然后搜索文件 server.xml
- 打开该文件并检查 HTTP 的连接器端口是什么，您会发现诸如 8009、8080 之类的内容。
- 假设它找到了 8009，使用 HTTP 协议在您的 Web 浏览器中将该端口用作“/localhost:8009/”。希望这会奏效！

Open your windows search bar, and search for the keyword Tomcat. If a shortcut file is found instead, you can open the source file location of the shortcut by right-clicking the shortcut file and selecting the Properties.
打开 Windows 搜索栏，然后搜索关键字Tomcat。如果找到快捷方式文件，您可以通过右键单击快捷方式文件并选择“属性”来打开快捷方式的源文件位置。
