1、maven 官网下载安装包

maven 官网地址：https://maven.apache.org/download.cgi

2、解压安装

tar -zxvf apache-maven-3.8.5-bin.tar.gz -C /usr/local/maven

3、创建 maven 资源库目录

mkdir -p /m2/repository

4、编辑 settings.xml 文件

  1. <?xml version="1.0" encoding="UTF-8"?>
  3. <settings xmlns="http://maven.apache.org/SETTINGS/1.2.0"
  4.           xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
  5.           xsi:schemaLocation="http://maven.apache.org/SETTINGS/1.2.0 https://maven.apache.org/xsd/settings-1.2.0.xsd">
  7.   <localRepository>/m2/repository</localRepository>
  9.   <pluginGroups>
  10.   </pluginGroups>
  12.   <proxies>    
  13.   </proxies>
  15.   <servers>
  16.   </servers>
  18.   <mirrors>
  19.     <mirror>  
  20.       <id>alimaven</id>  
  21.       <name>aliyun maven</name>  
  22.       <url>http://maven.aliyun.com/nexus/content/groups/public/</url>  
  23.       <mirrorOf>central</mirrorOf>          
  24.     </mirror> 
  25.   </mirrors>
  27.   <profiles>
  28.   </profiles>
  29. </settings>

5、添加环境变量

  1. vim /etc/profile.d/my_env.sh
  2. #Maven_HOME
  3. export MAVEN_HOME=/opt/module/maven/apache-maven-3.8.5
  4. export PATH=$PATH:$MAVEN_HOME/bin
  5. source /etc/profile
  6. #参考1、安装jdk配置环境变量

6、校验安装是否成功

mvn -version
