本章内容讲解在centos上搭建一些环境：

jdk11，maven3，git

## jdk11 安装 ##

首先安装jdk。我们到oracle官网下载jdk，

jdk11下载
    
    https://www.oracle.com/java/technologies/javase-jdk11-downloads.html
    
    
    更多版本下载
    
    https://www.oracle.com/java/technologies/javase-downloads.html
    
    
    解压下载的安装包
    
    tar -xzvf jdk-xxx.tar.gz
    
    编辑配置文件
    
    vi /etc/profile
    
    
    添加下面配置文件
    
    export JAVA_HOME=/usr/local/jdk11
    export CLASSPATH=.:$JAVA_HOME/jre/lib/rt.jar:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar
    
    
    source /etc/profile
    
    验证
    
    java -version
    
    java version "11.0.1" 2018-10-16 LTS
    Java(TM) SE Runtime Environment 18.9 (build 11.0.1+13-LTS)
    Java HotSpot(TM) 64-Bit Server VM 18.9 (build 11.0.1+13-LTS, mixed mode)

## maven安装 ##

下载包
    
    wget http://mirrors.hust.edu.cn/apache/maven/maven-3/3.1.1/binaries/apache-maven-3.1.1-bin.tar.gz
    
    
    解压后配置
    
    vi /etc/profile
    
    export M2_HOME=/usr/local/maven3
    export PATH=$PATH:$JAVA_HOME/bin:$M2_HOME/bin
    
    
    使配置生效
    source /etc/profile
    
    验证
    
    mvn -v 
    
    Apache Maven 3.1.1 (0728685237757ffbf44136acec0402957f723d9a; 2013-09-17 23:22:22+0800)
    Maven home: /usr/local/maven3
    Java version: 11.0.1, vendor: Oracle Corporation
    Java home: /usr/local/jdk11
    Default locale: en_US, platform encoding: UTF-8
    OS name: "linux", version: "3.10.0-1062.1.1.el7.x86_64", arch: "amd64", family: "unix"

##    git 安装 ##

更多方法参见官网
    
    
    直接安装
    https://git-scm.com/download/linux
    
    yum -y install git
    
    
    
    // ------------分割线----------
    
    
    
    源码编译
    https://mirrors.edge.kernel.org/pub/software/scm/git/
    
    wget https://mirrors.edge.kernel.org/pub/software/scm/git/git-2.9.0.tar.gz
    
    tar -zxvf git-2.9.0.tar.gz
    
    cd git-2.9.0 
    
    ./configure --prefix=/usr/local 
    
    make
    
    sudo make install
    
    
    
    验证
    
    git --version
    
    出现以下内容
    
    git version 1.8.3.1

## git绑定github     ##

首先生成公钥
    
    ssh-keygen -t rsa
    
    一直回车即可：
    出现以下画面
    
    Generating public/private rsa key pair.
    Enter file in which to save the key (/root/.ssh/id_rsa): 
    Enter passphrase (empty for no passphrase): 
    Enter same passphrase again: 
    Your identification has been saved in /root/.ssh/id_rsa.
    Your public key has been saved in /root/.ssh/id_rsa.pub.
    The key fingerprint is:
    SHA256:【这里特殊处理】
    The key's randomart image is:
    +---[RSA 2048]----+
    |                 |
    |           o     |
    |       . o=o     |
    |        o+*+o    |
    |       .S+.o++   |
    |    E ..o   =.=  |
    |   ..=.  .. *B o |
    |    o+=..  +.+=. |
    |    +X*+     ++..|
    +----[SHA256]-----+
    
    
    查看
    
    id_rsa.pub 复制里面内容到github中添加
    
    https://github.com/settings/keys
    
    名字可以随便写
