1.解压jdk
sudo tar -zxvf ./jdk-8u131-linux-x64.tar.gz -C /usr/lib/jvm
2.配置环境变量(配置3个地方)
（1）sudo gedit ~/.bashrc
#jdk
export JAVA_HOME=/usr/lib/jvm/jdk1.8.0_131
export JRE_HOME=${JAVA_HOME}/jre
export CLASSPATH=.:${JAVA_HOME}/lib:${JRE_HOME}/lib
export PATH=${JAVA_HOME}/bin:$PATH
source ~/.bashrc
(2)sudo gedit /etc/profile
#jdk
export JAVA_HOME=/usr/lib/jvm/jdk1.8.0_131
export JRE_HOME=${JAVA_HOME}/jre
export CLASSPATH=.:${JAVA_HOME}/lib:${JRE_HOME}/lib
export PATH=${JAVA_HOME}/bin:$PATH
source /etc/profile
(3) sudo gedit /etc/bash.bashrc
#jdk
export JAVA_HOME=/usr/lib/jvm/jdk1.8.0_131
export JRE_HOME=${JAVA_HOME}/jre
export CLASSPATH=.:${JAVA_HOME}/lib:${JRE_HOME}/lib
export PATH=${JAVA_HOME}/bin:$PATH
source /etc/bash.bashrc
(4）java -version
4, eclipse 安装
sudo tar -zxvf ./eclipse-inst-jre-linux64.tar.gz -C /usr/local/
5.创建图标启动
cd /usr/share/applications
sudo gedit eclipse.desktop
[Desktop Entry]
Encoding=UTF-8
Name=Eclipse
Comment=Eclipse
Exec=/usr/local/eclipse-installer/eclipse-inst
Icon=/usr/local/eclipse-installer/icon.xpm
Terminal=false
StartupNotify=true
Type=Application
Categories=Application;Development;
注释：
Exec=/usr/local/eclipse-installer/eclipse-inst (注：此为eclipse解压目录下的运行程序eclipse)
Icon=/usr/local/eclipse-installer/icon.xpm（注：此为eclipse解压目录下的icon图标）
(5) sudo chmod 777 /usr/share/applications/eclipse.desktop
启动eclipse，success！
遇到的问题：
启动eclipse一直报错：:/usr/bin/eclipse:3:/usr/local/eclipse/eclipse
原因是：eclipse 版本下载错误， eclipse-jee-2021-12-R-linux-gtk-aarch64 该版本不能执行。
