CentOS7 安装Maven

1. Maven下载地址：http://maven.apache.org/download.cgi，这里所用的版本号为3.6.0
2. 下载下来的压缩包上传到Centos中，并对压缩包进行解压：

tar zxf apache-maven-3.6.0-bin.tar.gz
mv apache-maven-3.6.0 maven

3. 配置maven环境变量

vim /etc/profile

添加环境变量

export JAVA_HOME=/root/jdk1.8.0_181
export MAVEN_HOME=/root/maven
export PATH=$JAVAP_HOME/bin:$PATH
export PATH=$MAVEN_HOME/bin:$PATH

4. 执行命令使环境变量生效，并验证版本

[root@localhost etc]# source profile
[root@localhost etc]# mvn -v

5. 打开maven配置文件，修改仓库为阿里云的仓库

修改内容
