随记-linux安装jdk8和maven3.8

环境：centos7.9，jdk8

jdk8包分享
jdk-8u221-linux-x64.tar.gz
maven3.8分享
apache-maven-3.8.6-bin.tar.gz

提取码：yyds

一、安装jdk8

1、上传服务器并解压
tar -zxvf jdk-8u221-linux-x64.tar.gz

2、编辑环境变量

vim /etc/profile

在最下面写入内容（JAVA_HOME改成自己的目录即可）

JAVA_HOME=/data/java/jdk1.8.0_221
CLASSPATH=.:$JAVA_HOME/lib.tools.jar
PATH=$JAVA_HOME/bin:$PATH
export JAVA_HOME CLASSPATH PATH

刷新环境配置and查看是否配置jdk成功

source /etc/profile
java -version

二、安装maven

1、上传到服务器、解压、创建一个资源库

tar -zxvf apache-maven-3.8.6-bin.tar.gz
mkdir respository

2、修改下maven的配置文件，换成国内阿里云的镜像

cd apache-maven-3.8.6/conf/
cp settings.xml settings-bak.xml 
vim settings.xml 

可删除那些注释内容，变得干净点，保留下面的即可

<?xml version="1.0" encoding="UTF-8"?>
 
<settings xmlns="http://maven.apache.org/SETTINGS/1.2.0"
          xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
          xsi:schemaLocation="http://maven.apache.org/SETTINGS/1.2.0 https://maven.apache.org/xsd/settings-1.2.0.xsd">
 
  <localRepository>/data/maven/repository</localRepository>
  
  <pluginGroups>

  <mirrors>
    <mirror>  
   	  <id>alimaven</id>  
   	  <name>aliyun maven</name>  
	  <url>http://maven.aliyun.com/nexus/content/groups/public/</url>  
   	  <mirrorOf>central</mirrorOf>          
    </mirror> 
  </mirrors>
 
  <profiles>
  
  </profiles>
</settings> 

3、编辑环境变量

 vim /etc/profile

写入内容

MAVEN_HOME=/data/maven/apache-maven-3.8.6
PATH=$MAVEN_HOME/bin:$PATH
export MAVEN_HOME PATH

4、刷新环境变量and查看maven配置是否成功

[root@hecs-169000 conf]# source /etc/profile
[root@hecs-169000 conf]# mvn -version
