下载maven：
官方地址：Maven – Download Apache Maven
解压maven：
[root@localhost ~]# tar xvf apache-maven-3.6.0-bin.tar.gz -C /opt/
配置环境变量/etc/profile或.~/.bash_profile文件：
[root@localhost ~]# vi /etc/profile #在最后两行添加 77 export M2_HOME=/opt/apache-maven-3.6.0 78 export PATH=$PATH:$M2_HOME/bin
让配置生效：
[root@localhost ~]# source /etc/profile
验证maven是否安装成功：
[root@localhost bin]# ./mvn -version which: no java in (/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/root/bin:/opt/apache-maven-3.6.0/bin) The JAVA_HOME environment variable is not defined correctly This environment variable is needed to run this program NB: JAVA_HOME should point to a JDK not a JRE #提示需要现安装jdk
安装jdk后验证：
[root@localhost ~]# mvn -version Apache Maven 3.6.0 (97c98ec64a1fdfee7767ce5ffb20918da4f719f3; 2018-10-25T02:41:47+08:00) Maven home: /opt/apache-maven-3.6.0 Java version: 1.8.0_192, vendor: Azul Systems, Inc., runtime: /opt/zulu8.33.0.1-jdk8.0.192-linux_x64/jre Default locale: zh_CN, platform encoding: UTF-8 OS name: "linux", version: "3.10.0-957.el7.x86_64", arch: "amd64", family: "unix"
至此就安装成功了
