centos7安装maven

首先在官网下载：http://maven.apache.org/download.cgi

apache-maven-3.6.2-bin.tar.gz

下载后用tar命令解压，我解压在/data目录下

编辑环境变量 vim /etc/profile    添加

#java环境变量
JAVA_HOME=/data/jdk1.8.0_212
JRE_HOME=/data/jdk1.8.0_212/jre
PATH=$PATH:$JAVA_HOME/bin:$JRE_HOME/bin
CLASSPATH=.:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar:$JRE_HOME/lib
export JAVA_HOME JRE_HOME PATH CLASSPATH
#maven环境变量
export MAVEN_HOME=/data/apache-maven-3.6.2
export PATH=${MAVEN_HOME}/bin:${PATH}

保存后更新环境变量source /etc/profile

执行：mvn -v

[root@centos7641 data]# mvn -v
