【问题描述】：

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

打开了从我的笔记本电脑到 ubuntu 服务器的 SSH 会话，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bin/che.sh -i run，得到这个：

sudo: unable to send audit message: Operation not permitted
bash: line 1:    10 Segmentation fault      (core dumped) sudo rm -rf /home/user/che/lib-copy/*

找到解决方案here：启动了这个

sudo usermod -aG docker useradm
logout

打开了新的 SSH 会话，再次运行 bin/che.sh -i run，得到了这个：

############## 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]
...
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"]

tomcat使用了8080端口，是否应该停止tomcat服务？

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还是显示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？

UPDATE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，现在可以了:)

【解决方案1】：

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，这是我得到的：

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，不带参数，如果出现问题，这个命令会显示错误
