一、配置安装环境

#安装wget
yum install -y wget
#安装jdk17
#创建jdk存放目录
mkdir -p /usr/local/java
#切换目录
cd /usr/local/java
#下载jdk17
wget https://download.java.net/java/GA/jdk17.0.1/2a2082e5a09d4267845be086888add4f/12/GPL/openjdk-17.0.1_linux-x64_bin.tar.gz
#解压jdk17
tar -xzvf openjdk-17.0.1_linux-x64_bin.tar.gz -C /usr/local/java/
#配置环境变量
sed -i '$a export JAVA_HOME=/usr/local/java/jdk-17.0.1' /etc/profile
sed -i '$a export JRE_HOME=${JAVA_HOME}/jre' /etc/profile
sed -i '$a export CLASSPATH=.:${JAVA_HOME}/lib:${JREHOME}/lib:$CLASSPATH' /etc/profile
sed -i '$a export JAVA_PATH=${JAVA_HOME}/bin:${JRE_HOME}/bin' /etc/profile
sed -i '$a export PATH=$PATH:${JAVA_HOME}/bin:${JRE_HOME}/bin' /etc/profile
#重新加载环境变了
source /etc/profile
#验证jdk
java -version
