在Ubuntu下安装Java运行环境

系统版本：Ubuntu19.04
安装时间：2020/04/26

step1 下载Java SE包

首先进入这个网址:https://www.oracle.com/java/technologies/，然后进入Java SE。
JavaSE
或者是直接选择Newest Download里面的最新版JavaSE
targz
在Java SE xx(数字)下选择JDK Download
homedownload
进入之后选择tar.gz的包下载，这种包不需要经过编译，更加方便

下载之后一般~/home/Download文件夹下面

step2 解压

tiqu
然后将文件解压。直接右键提取到此处即可。得到一个文件夹jdk-14.0.1_linux-x64_bin
fitableversion
然后打开控制台将该解压出的文件夹移动到/usr/lib下面。(虽然是非必要的，但是usr文件夹下是存放安装的软件相关数据的，我比较习惯放到这里)
sudo mv jdk-14.0.1_linux-x64_bin /usr/lib

step3 生效

方式一：修改全局配置文件使其生效

打开 /etc/profile文件。
可以用vim/vi/nano/gedit什么都行，只要能编辑就行。不适应用命令行界面的可以用sudo gedit /etc/profile
然后在文件的末尾加上下面的内容

export JAVA_HOME=/usr/lib/jdk-14.0.1_linux-x64_bin/jdk-14.0.1 //注意这里要更往下一级
export CLASSPATH=.:${JAVA_HOME}/lib
export PATH=.:${JAVA_HOME}bin:$PATH

然后 source /etc/profile，然后重启即可

方式二：修改当前用户配置文件使其生效

打开 ~/.bashrc文件,在末尾加上上面同样的内容，然后执行 source ~/.bashrc即可。

step4 验证安装是否成功

打开控制台，输入java --version，如果打印出java的版本信息即可。
顺便检查一下java编译器 javac --version。
fitableversion

安装Control System Studio

Control System Studio这个东西资料真的不多，中文搜根本搜不到任何东西。
去这个地方http://controlsystemstudio.org/controlsystemstudio/current.html打开下载列表选择适合自己系统版本的CS Studio
structure
下载之后移动到自己想要的地方解压即可。4.5.9-linux.gtk.x86_64.tar.gz解压之后的文件夹结构如下.其中cs-studio是可执行文件。
startup1

启动CS Studio以及问题修复

启动css的时候
workspace
head
但是程序崩了，并且出现了报错信息:

An erro has occurred.see the log file xxx

去看了一下对应的log文件，一次出错的大致内容如下：

我们注意到，主要有下面三个地方的错误要留意：

首先开头这个地方中有一个eclipse.buildId = unknown
这个Message不能绑定引用
有一个类的定义找不到

查到最有用的一个资料是这个，这个人遇到的问题与我极其相似，虽然他这是MacOS
https://github.com/ControlSystemStudio/cs-studio/issues/2561
这个回答如果看不太懂可以看下面这个人给出的链接
8u251
简单的说原因如下：Java版本不适合，需要使用java 1.8(也即Java 8)，之前我们装的是Java 14.
在之前的下载页面下拉，可以看到一个Java SE 8xxxx，比我现在看到的是8u251

下载对应的JDK，下载之后解压，解压之后进入文件夹，然后还有两个zip文件需要解压。把这两个也解压了，然后按照之前的方式配置生效，把JAVA_HOME的路径修改称JAVA 1.8的路径即可。
csstudiostartup
再测试一下
cannotgoto
再启动cs studio就可以了

CS Studio的尝试使用、遇到的问题以及解决

CS Studio这个东西究竟该怎么用？
进入CSS之后的welcome界面，first steps->introduciton to CS-Studio不知道为什么打不开
cangotogoogle
我一度怀疑是不是我的虚拟机下没有翻墙，所以显示不出来。于是我想办法让我的虚拟机翻出去之后再试，然而还是进不去

下面的probe和 BOY 点了之后一点反应都没有
tutorial点开之后什么内容都没有

找到一个CSS的使用的pdf:https://epics.anl.gov/docs/USPAS2014/1-Monday/CSS_2_First_Steps.pdf
但是这个东西好像有点老了，有些内容已经不适用了。比如这个

但是CS Studio菜单下根本就没有trend这个子菜单。而且下面的子菜单也没有包含Data Browser这个选项。
而且这个地方说可以查看help文档

但是我 help->help context一点反应都没有。只能通过windows → show view->help才能看到这个窗口

而且这里面的文档也是无法访问的

其他地方几乎搜不到任何关于如何使用CS-Studio的文章或者教程。在Control System Studio Guide Chapter1 introduction里面说到，使用者参考help文档即可(help->help context)但是我这个的help context一直打不开。
于是我又去看了下日志文件。大致内容如下：

发现还是存在以下的问题：

eclipseId=unknown
还是有MESSAGE不能绑定引用
缺少一个png图标文件
有个类的定义找不到，这个我查了资料之后得知，要想能够看到help文档就要用到这个类

我找到资料说这个CS-Studio是基于Eclipse的，所以我在想是不是因为我没有装Eclipse所以缺少了库文件之类的，
我再去看了看下载的界面发现的确有说需要Eclipse Neon 4.6的

于是我在Ubuntu下安装了Eclipse Neon。但是仍然没有起作用。

找到的和我遇到的问题比较接近的是这个： https://epics.anl.gov/tech-talk/2017/msg00396.php
忘了最终是在哪搜到的解决方案，但是最终找到的有用的页面是这个https://controlssoftware.sns.ornl.gov/
这个他说这个SNS Control Software Tools才是适用于EPICS的
我选择的是第二个(点击More)。因为他说这个已经应用到了很多地方，所以我觉得这个应该更加稳定一些。

重新下载安装这个版本，然后help文档就可以用了。

虽然Welcome页面似乎还是不能用的样子。

log文件的内容大概是这样的。

这次eclipseId=unknown终于没有再出现了。
但是另外出现的两个问题是连接到两个地址失败了。这两个网址猜测应该是和welcome页面相关的

本文章使用limfx的vsocde插件快速发布

在Ubuntu下安装Java运行环境和CS-Studio，并解决CS-Stuidio无法启动以及无法查看help文档的问题
