https://download.youkuaiyun.com/download/maple980326/10326992

software 下创建 jdk 目录
将 jdk-8u161-linux-x64.tar扔进去
tar  -zxvf  jdk-8u161-linux-x64.tar.gz
编辑 /etc/profile
export JAVA_HOME=/usr/local/software/jdk/jdk1.8.0_161
export JRE_HOME=${JAVA_HOME}/jre
export CLASSPATH=.:${JAVA_HOME}/lib:${JRE_HOME}/lib:$CLASSPATH
export JAVA_PATH=${JAVA_HOME}/bin:${JRE_HOME}/bin
export PATH=$PATH:${JAVA_PATH}
执行一下命令
source /etc/profile
java -version
在 /usr/local/下创建 apps
cd /usr/local/apps
把 light-application-0.0.1-SNAPSHOT.jar扔进去 
java -jar /usr/local/apps/light-application-0.0.1-SNAPSHOT.jar

当执行 source /etc/profile java -version 后可能会出现问题

-bash: /usr/serverApp/jdk1.8.0_161/bin/java: Permission denied

执行 chmod 777 jdk1.8.0_161/bin/java
