在linux下編譯java程序，執行javac編譯生成class文件時，在centos7終端輸入如，javac hello.java 會提示未找到指令，但用java -verison測試環境變量是沒問題的java

百度了很久，說的很複雜，從新再linux配置環境變量，輸入 vi /etc/profile進入，添加如下代碼：linux

export JAVA_HOME=/usr/local/jdk1.8.0_144
export PATH=$JAVA_HOME/bin:$PATH
export CLASSPATH=.:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar

再測試，最後也沒有成功centos

後來在stackoverflow上看到了這個ide

You installed the Java Runtime Environment (JRE) only, which does not contain javac. For javac, you have to install the OpenJDK Development Environment. You can install java-devel or java-1.6.0-openjdk-devel, which both include javac.測試

By the way: you can find out which package provides javac with a yum search, e.g.centos7

su -c 'yum provides javac'
Another note: using yum and openjdk is only one possibility to install the JDK. Many people prefer Sun/Oracle's "original" SDK. See How to install Java SDK on CentOS? and links for alternatives.spa

大意就是咱們用yum來裝原生的就好了.net

在終端輸入code

yum install java-develblog

執行安裝

再測試就好了

補充：Vi編輯經常使用快捷鍵

複製：ctrl+insert

粘貼：shift+insert

按Esc保存退出編譯，shift+zz退出本文轉自：https://blog.csdn.net/yalecaltech/article/details/70158620
