无法在ubuntu下运行Ecplise Che

Question

我想在远程ubuntu 14.04服务器上安装Eclipse Che IDE。这是我所做的：

1. 打开了从我的笔记本电脑到ubuntu服务器的SSH会话，以“useradm”身份登录
2. 按照此URL安装docker
3. 在/home/useradm/我下载了一个TAR。GZ文件从此处开始
4. 已运行bin/che。sh-我运行，得到以下结果：

############## HOW TO CONNECT YOUR CHE CLIENT ###############
After Che server has booted, you can connect your clients by:
...
15:04:36,897 |-INFO in ch.qos.logback.core.rolling.RollingFileAppender[file] - File property is set to [null]
15:04:36,899 |-ERROR in ch.qos.logback.core.rolling.RollingFileAppender[file] - Failed to create parent directories for [/home/user/che/tomcat/logs/2016/05/26/catalina-0.log]
...
2016-05-26 15:04:38,608[ost-startStop-1]  [ERROR] [o.a.j.EmbeddedServletOptions 692]    - The scratchDir you specified: /home/user/che/tomcat/work/Catalina/localhost/dashboard is unusable.
...
2016-05-26 15:04:42,025[main]             [INFO ] [o.a.c.http11.Http11NioProtocol 514]  - Stopping ProtocolHandler ["http-nio-8080"]
2016-05-26 15:04:42,026[main]             [INFO ] [o.a.c.http11.Http11NioProtocol 529]  - Destroying ProtocolHandler ["http-nio-8080"]

我的步子怎么了？：（

从我的浏览器，http://172.16.16.11:8080/工作正常：

这是默认的Tomcat主页。它可以在本地文件系统上找到： /var/lib/tomcat7/webapps/ROOT/index.html

我是否必须将Che文件从/home/useradm/移动到/var/lib/tomcat7/webapps/ROOT/或不移动？

更新：我运行了bin/che。sh run（没有任何参数），我得到了以下结果：

[ERROR] [o.a.c.http11.Http11NioProtocol 460]  - Failed to initialize end point associated with ProtocolHandler ["http-nio-8080"]

8080端口被tomcat使用，我应该停止tomcat服务吗？

更新：我是对的：）我阻止了tomcat：

sudo服务tomcat7停止

我得到了这个：

############## HOW TO CONNECT YOUR CHE CLIENT ###############
After Che server has booted, you can connect your clients by:
1. Open browser to http://localhost:8080, or:
2. Open native chromium app.

Server startup in 6151 ms

但是http://172.16.16.11:8080仍然显示tomcat主页，而不是Che界面！？当它显示“http://localhost:8080”而不是服务器IP时，这是正常的消息吗？

更新这是浏览器缓存问题，我停止了Che，重新加载http://172.16.16.11:8080，404，我再次运行Che，现在一切正常：）

正确的步骤是：

1. 在任何文件夹中卸载文件

sudo add-apt-repository ppa:webupd8team/java
sudo apt-get update
sudo apt-get install oracle-java8-installer

export JAVA_HOME=/usr/lib/jvm/java-8-oracle/jre
export PATH=$JAVA_HOME/bin:$PATH` 
WARNING : you have to point to the folder witch contains le "lib" one, to find your java install folder use this : `readlink -f $(which java)
