2，安装

首先需要安装 docker。使用 CentOS7 直接 yum 安装：启动 docker。

yum -y install docker
service docker start
systemctl enable docker
# 增加开机启动。

eclipse che 下载地址：
http://www.eclipse.org/che/
开源的技术发展的真快，已经开始折腾云 IDE 了。
看看这个是用啥技术实现的。

github 项目地址：
https://github.com/eclipse/che/
看了看项目的 ide，居然是用 GWT 开发的。挺怀念的，之前一直研究这个，可惜没有使用上。

各种报错：

!!!
!!! Running 'docker' succeeded, but 'docker ps' failed. This usually means that docker cannot reach its daemon.
!!!
############################ 这个是因为 docker 服务没有启动。执行 service docker start，一定要有 docker 服务。!!!
!!! This Linux user is not in docker group. See https://docs.docker.com/engine/installation/Ubuntulinux/#create-a-docker-group

!!! This Linux user was launched with a UID != 1000. Che must run under UID 1000. See https://eclipse-che.readme.io/docs/usage#section-cannot-create-projects

!!!
############################ 因为组设置的不对，创建 docker 用户。useradd docker
gpasswd -a docker root
sudo su docker
sh bin/che.sh run

!!!
!!! JAVA_HOME is not set. Please set to directory of JVM or JRE.
!!!
修改 /home/docker/.bashrc 最后一行增加
#add JAVA_HOME
export JAVA_HOME=/usr/java/default
export PATH=$JAVA_HOME/bin:$PATH
export CLASSPATH=.:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar

!!!
!!! Che requires Java version 1.8 or higher. We found 1.7.0_75.
!!!
必须安装 jdk 1.8

成功启动：

############## 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.

3，使用

成功启动之后就可以看到面板页面：
Eclispse Che（1）：CentOS 7 安装 che 服务
可以创建一个新的项目：

遇到一个问题，从 docker 官网下载镜像出现问题。

可以使用国内的几个镜像解决。
不在这里讨论了。

4，总结

eclipse che 都已经发布到 4 的版本了。还没有咋研究呢。
总体感觉上肯定没有本地 IDE 功能强大。
思路挺好的。可以将 docker 结合起来，而且还开源，将来做一些云服务，还是挺好的。
由于国内网络问题，没有进入工作界面。
只要有网络的地方，使用浏览器都能让码农干活。
这种项目最好还是不要发明出来的好！！！
