安装 Java

yum install java-11-openjdk java-11-openjdk-devel

配置环境变量

vi /etc/profile

最后加入

#set java environment
export JAVA_HOME=/usr/lib/jvm/java-11-openjdk-11.0.8.10-0.el7_8.x86_64
export JRE_HOME=$JAVA_HOME/jre
export PATH=$PATH:$JAVA_HOME/bin:$JRE_HOME/bin

使配置的环境变量生效

source /etc/profile

运行测试

java -version
javac

安装 Maven

wget https://mirrors.aliyun.com/macports/distfiles/maven3/apache-maven-3.6.3-bin.tar.gz
tar -zxvf apache-maven-3.6.3-bin.tar.gz
mv apache-maven-3.6.3 maven
mv maven /usr/local/

编辑环境

vi /etc/profile

在文件末尾添加

#maven
export  MAVEN_HOME=/usr/local/maven
export  PATH=${JAVA_HOME}/bin:/usr/local/mysql/bin:${MAVEN_HOME}/bin:$PATH

source /etc/profile

验证安装是否成功
