1: 下载 maven    我采用的是  apache-maven-3.3.9-bin.tar.gz

      http://maven.apache.org/download.cgi

2:  解压  tar –zxvf apache-maven-3.3.9-bin.tar.gz

3:  创建软连接 ln -s apache-maven-3.3.9

4:  添加环境变量 ：vim /etc/profile  

           添加内容  export MAVEN_HOME=/usr/local/maven

                     export PATH=$PATH: $MAVEN_HOME/bin

5; 使之生效 source /etc/profile

6: 查看是否安装成功 mvn –v     如果出现下面内容则成功
