一 下载maven bin包并解压

$ wget http://mirror.bit.edu.cn/apache/maven/maven-3/3.3.9/binaries/apache-maven-3.3.9-bin.tar.gz 
$ tar - zxvf apache-maven-3.3.9-bin.tar.gz 
$ sudo mv apache-maven-3.3.9 /usr/local/

　　

二 配置maven环境变量

将如下内容添加到/etc/profile中　

export M2_HOME=/usr/local/apache-maven-3.3.9 
export PATH=$PATH:$M2_HOME/bin

　　执行source /etc/profile使环境变量生效

三 检查是否安装成功
