**前言**：*本次安装是在CentOS7的虚拟机环境下进行的安装。*

**CentOS7镜像资源**:链接：[https://pan.baidu.com/s/13wTlzj4WzkUvC1Tg4e06Lw][https_pan.baidu.com_s_13wTlzj4WzkUvC1Tg4e06Lw]  提取码：pd3r

**一.准备工作**

1.**准备安装包**:JDK安装tar.gz包    /Maven安装tar.gz包      /Tomcat安装tar.gz包

2.windows10下安装**Xshell**和**Xft**

3.**资源地址**:https://pan.baidu.com/s/1l\_xHbl5kTUMe-42KByEHYQ  提取码：941a

**二.安装虚拟机**：

1.**使用VMware经典模式安装（快速安装模式),设置分配磁盘大小20G,并设置初始用户（一定要记住密码：此密码同步root用户）。**

**2.改用root用户登录**

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L0NDSUVKb2huX3pob3U_size_16_color_FFFFFF_t_70 1][]

**4.开启多用户模式（必须用root开启多用户，其他用户权限不够。以\#开头就表示当前使用的是root用户）**

**指令：systemctl set-default multi-user.target  //开启多用户**

**指令：reboot  //重启系统**

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L0NDSUVKb2huX3pob3U_size_16_color_FFFFFF_t_70 3][]

**多用户模式：即以黑窗口模式开始操作虚拟机。**

![20190412191832711.png][]

**8.遇到的问题：安装的是java1.8 ，但是java -version 出现的是java1.7的版本**

*如果出现这个问题并不是你的配置信息有问题，而是你的jdk1.8被原有自带的jre1.7给顶掉了。*

**如何解决？**

**方法一：**

8.1**查找**：rpm  -qa | grep java   //找到正在运行的java软件

8.2**删除**：rpm -e  --nodeps  找到的java软件名      //删除两个java文件
