## 一、入门初始安装 ##

### 1. 具体安装教程 ###

#### 安装包下载链接 ####

[Java 的 tar.gz 安装包下载链接传送门][Java _ tar.gz]

#### Linux 系统的 Java 环境变量配置教程 ####

[1. linux查看java版本，以及配置java home][1. linux_java_java home]

[2. Linux环境下如何配置JAVA\_HOME][2. Linux_JAVA_HOME]

[3.【实操】如何在linux系统查找JAVA安装路径,定义JAVA\_HOME][3._linux_JAVA_JAVA_HOME]

[4. Linux配置java\_home][4. Linux_java_home]

### 个人理解 ###

[root@linuxprobe home]# cat /etc/system-release  ## 查看系统版本
    Red Hat Enterprise Linux release 8.0 (Ootpa)
    [root@linuxprobe home]# java  ##检测是否安装java
    bash: java: command not found...
    Failed to search for file: Cannot update read-only repo
    [root@linuxprobe home]# java -version   ## 查看版本
    bash: java: command not found...
    Failed to search for file: Cannot update read-only repo
    [root@linuxprobe home]# which java  ## 是否有java执行命令
    /usr/bin/which: no java in (/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/root/bin)
    [root@linuxprobe home]# uname -a  ## 查看系统内核、架构
    Linux linuxprobe.com 4.18.0-80.el8.x86_64 #1 SMP Wed Mar 13 12:02:46 UTC 2019 x86_64 x86_64 x86_64 GNU/Linux
    [root@linuxprobe home]# hostnamectl  ## 同上
       Static hostname: linuxprobe.com
             Icon name: computer-vm
               Chassis: vm
            Machine ID: 1667052376ea4207aa566e9d7a42456b
               Boot ID: c37ae01cf99e40909900fa77495cca76
        Virtualization: vmware
      Operating System: Red Hat Enterprise Linux 8.0 (Ootpa)
           CPE OS Name: cpe:/o:redhat:enterprise_linux:8.0:GA
                Kernel: Linux 4.18.0-80.el8.x86_64
          Architecture: x86-64

![在这里插入图片描述][5d664bd84d294112a4428c04185b1db1.png]

查看本机系统，如果 Linux系统是 `x86_64`（[x86-64][]）的，那么无疑是本次教程的默认安装教程路线。
