centos7下部署maven环境

1.安装前提
基于jdk，要高于1.7。
执行java -version查看是否已安装jdk，如未安装则需要安装java环境
2.下载maven
官方下载地址：http://maven.apache.org/download.cgi
执行wget https://mirrors.tuna.tsinghua.edu.cn/apache/maven/maven-3/3.8.8/binaries/apache-maven-3.8.8-bin.tar.gz下载

[root@nexus ~]# wget https://mirrors.tuna.tsinghua.edu.cn/apache/maven/maven-3/3.8.8/binaries/apache-maven-3.8.8-bin.tar.gz

3.解压maven包并进入maven目录
解压maven包至指定目录/usr/local/
tar xvf apache-maven-3.8.8-bin.tar.gz -C /usr/local/
cd /usr/local/apache-maven-3.8.8
4.配置环境变量并验证
vim /etc/profile
增加以下几行内容，source /etc/profile，使环境变量生效，mvn -v查看是否安装成功

[root@nexus local]# vim /etc/profile

MAVEN_HOME=/usr/local/apache-maven-3.8.8
PATH=$JAVA_HOME/bin:$MAVEN_HOME/bin:$PATH
export JAVA_HOME MAVEN_HOME PATH

[root@nexus local]# source /etc/profile
[root@nexus local]# mvn -v
