在linux下编译java程序，执行javac编译生成class文件时，在centos7终端输入如，javac hello.java 会提示未找到指令，但用java -verison测试环境变量是没问题的java

百度了很久，说的很复杂，从新再linux配置环境变量，输入 vi /etc/profile进入，添加如下代码：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

再测试，最后也没有成功centos

后来在stackoverflow上看到了这个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.测试

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

大意就是咱们用yum来装原生的就好了.net

在终端输入code

yum install java-develblog

执行安装

再测试就好了

补充：Vi编辑经常使用快捷键

复制：ctrl+insert

粘贴：shift+insert

按Esc保存退出编译，shift+zz退出本文转自：https://blog.csdn.net/yalecaltech/article/details/70158620
