maven 去官网下载

 在linux 服务中

wget http://mirrors.tuna.tsinghua.edu.cn/apache/maven/maven-3/3.6.2/binaries/apache-maven-3.6.2-bin.zip

下载完成解压缩　　

unzip  apache-maven-3.6.2-bin.zip

配置mvn环境变量

vim /etc/profile

最底下加入2行代码, 请对应自己maven解压目录

export MAVEN_HOME=/root/maven/apache-maven-3.6.2
export PATH=$MAVEN_HOME/bin:$PATH

 :wq 保存 刷新profile 文件

. /etc/profile

验证是否安装成功

mvn -version
