<>一、概述
如果需要在Linux下进行JavaEE的开发,我们需要安装如下软件:
* ideaIU-2020.2.3.tar.gz
* apache-tomcat-8.5.59.tar.gz
* CentOS-7-x86_64-DVD-1810.iso
* jdk-8u261-linux-x64.tar.gz
* mysql-8.0.26-1.el7.x86_64.rpm-bundle.tar
<>二、安装JDK步骤
* mkdir /opt/jdk
* 通过xftp6上传到/opt/jdk下
* cd /opt/jdk
* 解压tar -zxvf jdk-8u261-linux-x64.tar.gz
* mkdir /usr/local/java
* mv /opt/jdk/
* 配置环境变量的配置文件:vim /etc/profile
* export JAVA_HOME=/usr/local/java/jdk1.8.0_261
export PATH= J A V A H O M E / b i n : JAVA_HOME/bin: JAVAHOME/bin:PATH
9.source /etc/profile 让新的环境变量生效
测试是否安装成功
编写一个简单的hello.java 输出“hello,world”
vim hello.java
