centos6.9安装maven3.6.3

　　在root下进入/usr/lib目录，从官网下载最新版本3.6.3的tar包，解压：

[root@VM-0-14-centos ~]# cd /usr/local
[root@VM-0-14-centos local]# wget https://mirror.bit.edu.cn/apache/maven/maven-3/3.6.3/binaries/apache-maven-3.6.3-bin.tar.gz

[root@VM-0-14-centos local]# tar xvf apache-maven-3.6.3-bin.tar.gz

　　删除压缩包，配置环境变量：

[root@VM-0-14-centos local] rm -f apache-maven-3.6.3-bin.tar.gz
[root@VM-0-14-centos local] cd /etc/profile.d
[root@VM-0-14-centos profile.d]# vim maven.sh

M2_HOME=/usr/local/apache-maven-3.6.3
PATH=$PATH:$M2_HOME/bin
export M2_HOME PATH

　　让以上配置的maven环境变量生效：

[root@VM-0-14-centos profile.d]# source /etc/profile
[root@VM-0-14-centos profile.d]# echo $M2_HOME
/usr/local/apache-maven-3.6.3
[root@VM-0-14-centos profile.d]# mvn -v

　　打完收工，最后配置一下setting文件：

[root@VM-0-14-centos profile.d]# cd ~
[root@VM-0-14-centos ~]# vi /usr/local/apache-maven-3.6.3/conf/settings.xml

　　因为我之前设置过nexus的私服（参见使用nexus3.19搭建自己的maven私服），直接把那个setting文件拿过来用即可：

<?xml version="1.0" encoding="UTF-8"?>
