一、配置安裝環境

#安裝wget
yum install -y wget
#安裝jdk17
#創建jdk存放目錄
mkdir -p /usr/local/java
#切換目錄
cd /usr/local/java
#下載jdk17
wget https://download.java.net/java/GA/jdk17.0.1/2a2082e5a09d4267845be086888add4f/12/GPL/openjdk-17.0.1_linux-x64_bin.tar.gz
#解壓jdk17
tar -xzvf openjdk-17.0.1_linux-x64_bin.tar.gz -C /usr/local/java/
#配置環境變量
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
#重新加載環境變了
source /etc/profile
#驗證jdk
java -version

二、下載安裝maven

Maven – Download Apache Maven? maven官方下載鏈接

1、創建maven插件存放目錄
mkdir -p /usr/local/maven/
2、切換目錄
cd /usr/local/maven
3、下載maven
yum install -y wget
wget https://dlcdn.apache.org/maven/maven-3/3.9.6/binaries/apache-maven-3.9.6-bin.tar.gz
4、解壓maven
tar -xzvf apache-maven-3.9.6-bin.tar.gz
5、配置 /etc/profile 底部添加底部代碼
#############profile###########################
export MAVEN_HOME=/usr/local/software/maven/apache-maven-3.6.3
PATH=$JAVA_HOME/bin:$MAVEN_HOME/bin:$PATH
#################################################
6、重新運行 /etc/profile
source /etc/profile
7、驗證mvn
mvn -v
