ubuntu - ubuntu下无法运行Eclipse 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:

打开从我的笔记本电脑到 ubuntu 服务器的 SSH session ，以“useradm”

身份登录

关注 this URL安装 docker

在/home/useradm/我从 here 下载了一个 TAR.GZ 文件

跑了bin/che.sh -i run ，得到这个:

找到解决方案here : 推出这个

sudo usermod -aG docker useradm
logout

打开新的 SSH session ，运行 bin/che.sh -i run再次，得到这个:

############## 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]

我的步骤有什么问题？ :(

在我的浏览器中， http://172.16.16.11:8080/工作正常:
This is the default Tomcat home page. It can be found on the local filesystem at: /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/？

更新 : 我跑了 bin/che.sh run (没有任何参数)，我得到了这个:

[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:)我停止了tomcat:
sudo service tomcat7 stop
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，不是Che界面!？当它显示“ http://localhost:8080”而不是服务器 IP 时是正常消息吗？

更新 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，现在可以了 :)

正确的步骤是:

在任意文件夹中解压文件

安装 JRE 8:

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

检查java版本:java -version ，我得到了:

useradm@modlamp01:~/eclipse-che-4.0.1$ java -version
java version "1.8.0_91"
Java(TM) SE Runtime Environment (build 1.8.0_91-b14)
Java HotSpot(TM) 64-Bit Server VM (build 25.91-b14, mixed mode)

设置 JAVA_HOME 变量:

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)

确保 8080 端口空闲

运行这个:bin/che.sh run没有参数，如果出现问题，此命令会显示错误
