1、上传到linux,使用tar命令解压Maven包

[root@hadoop102 software]# tar -xzvf apache-maven-3.3.9-bin.tar.gz -C /opt/module/

2、查看解压后Maven

3、编辑/etc/profile,配置maven环境变量

[root@hadoop102 jdk1.8.0_144]# vim /etc/profile
##MAVEN_HOME
export MAVEN_HOME=/opt/module/apache-maven-3.3.9
export MAVEN_REPO=/opt/module/apache-maven-3.3.9/m2/repository
export PATH=$PATH:$MAVEN_HOME/bin

4、maven 的 settings.xml 配置

    <localRepository>/opt/module/apache-maven-3.3.9/m2/repository</localRepository>
    <mirror>
        <id>nexus-aliyun</id>
        <name>Nexus aliyun</name>
        <url>http://maven.aliyun.com/nexus/content/groups/public/</url>
        <mirrorOf>central</mirrorOf>
    </mirror>

    <mirror>
        <id>repo2</id>
        <name>Mirror from Maven Repo2</name>
        <url>http://repo2.maven.org/maven2/</url>
        <mirrorOf>central</mirrorOf>
    </mirror>

    <mirror>
        <id>centor</id>
        <name>Mirror from Maven central</name>
        <url>http://central.maven.org/maven2/</url>
        <mirrorOf>central</mirrorOf>
    </mirror>
    
    <profile>
        <id>jdk-1.8</id>
        <activation>
            <activeByDefault>true</activeByDefault>
            <jdk>1.8</jdk>
        </activation> 
        <properties>
            <maven.compiler.source>1.8</maven.compiler.source>
            <maven.compiler.target>1.8</maven.compiler.target>
            <maven.compiler.compilerVersion>1.8</maven.compiler.compilerVersion>
        </properties>
    </profile>

5、查看maven环境变量是否配置成功

[root@hadoop102 scala-2.11.8]# source /etc/profile
[root@hadoop102 apache-maven-3.3.9]# mvn -v
