linux 安裝jdk/maven__linux

新的伺服器，首先需要裝必備的環境

以下使用centos 7,選用centos7主要是docker需要3.0以上核心，免去升級核心麻煩

1、jdk

先檢查是否有安裝

# java -version

如果有安裝先卸載掉

1.1下載jdk

首先到jdk官網上下載你想要的jdk版本，我下載的是jdk-8u152-linux-x64.tar.gz，上傳到伺服器，如下

#mkdir -p/opt/mysoft

#cd/opt/mysoft

#rz jdk-8u152-linux-x64.tar.gz

#tar -zxvf jdk-8u152-linux-x64.tar.gz /usr/local/java/

1.2配置jdk環境

# vim /etc/profile

在文未追加以下內容，儲存

#JAVA HOME  JAVA_HOME="/usr/local/java/jdk1.8.0_152"  CLASS_PATH="$JAVA_HOME/lib:$JAVA_HOME/jre/lib"  PATH=".:$PATH:$JAVA_HOME/bin"    export JAVA_HOME  export CLASS_PATH  export PATH  

#source /etc/profile 執行後立即生效

查看jdk版本，如下，配置成功
#java -version
java version "1.8.0_152"
Java(TM) SE Runtime Environment (build 1.8.0_152-b16)
Java HotSpot(TM) 64-Bit Server VM (build 25.152-b16, mixed mode)

2、maven

2.1下載maven

官網下載maven我下載的是apache-maven-3.5.2-bin.tar.gz

#cd /opt/mysoft

#rzapache-maven-3.5.2-bin.tar.gz

#tar -zxvf apache-maven-3.5.2-bin.tar.gz /usr/local/program/

2.2配置maven

修改settings檔案，設定本地Repository地址與鏡像

<localRepository>/opt/maven</localRepository>

 <mirror>
      <id>alimaven</id>
      <mirrorOf>central</mirrorOf>
      <name>aliyun maven</name>
     <url>http://maven.aliyun.com/nexus/content/repositories/central/</url>
    </mirror>

#vim /etc/profile 文末追加

export MAVEN_HOME=/usr/local/program/apache-maven-3.5.2  export PATH=${PATH}:${MAVEN_HOME}/bin  

#source /etc/profile 執行後立即生效

查看maven版本，如下配置成功 #mvn -v 
Apache Maven 3.5.2 (138edd61fd100ec658bfa2d307c43b76940a5d7d; 2017-10-18T15:58:13+08:00)
