**centos7****之安装jdk1.8，安装tomcat9的粗暴简单教程**

不出错的情况下可以一次完成。出错的时候自行百度吧。！！！

一、下载需要的文件

1.  进入jdk官网下载jdk—我是使用centos里的火狐浏览器下载的。

地址如下：

[https://www.oracle.com/technetwork/java/javase/downloads/index.html][https_www.oracle.com_technetwork_java_javase_downloads_index.html]

这里我们下载1.8版本的jdk，页面往下滚动可以看到如下图的。点红框里的download

![70][]

下载压缩包格式的jdk

![70 1][]

下载完成后可以在download文件夹里找到下好的文件

1.  下载tomcat

进入Apache官网进行下载

[https://www.apache.org/][https_www.apache.org]

点击projects

![70 2][]

在项目列表里找到tomcat

![70 3][]

在左侧download里选择tomcat9—我选择的是9版本的。

![70 4][]

下载tar.gz格式的压缩包。

![70 5][]

二、安装

找到下载路径

选择在终端打开，downloads文件夹里已经有我下好的tomcat和jdk两个压缩包了。

![70 6][]

将文件复制到想要的地方

如果权限不够的话就是用root权限进行操作。

先进入/usr下创建一个my文件夹，然后将两个文件复制到这个文件夹下

![70 7][]

![70 8][]

然后进入/usr/my文件夹

将两个压缩包解压到当前文件夹

\# tar -zxvf jdk-8u181-linux-x64.tar.gz

\# tar -zxvf apache-tomcat-9.0.12.tar.gz

解压后多了两个文件夹

![70 9][]

为了名字好打一些，重命名一下。但是由于linux没有提供重命名方法，所以只能使用mv命令进行

mv oldfilename newfilename (mv 旧文件夹名 新文件夹名)

\# mv jdk1.8.0\_181 jdk

\# mv apache-tomcat-9.0.12 tomcat

![70 10][]

因为是压缩包形式的文件，所以不需要安装，只需要配置环境变量就可以了。

现在我们来配置java的路径

\#vi /etc/profile

![70 11][]

在最后面加上一段代码

JAVA\_HOME=/usr/my/java

PATH=$JAVA\_HOME/bin:$PATH

CLASSPATH=.:$JAVA\_HOME/lib/dt.jar:$JAVA\_HOME/lib/tools.jar

export JAVA\_HOME

export PATH

export CLASSPATH

保存后重启或执行命令，然后查看java版本。测试javac命令能否使用。

![70 12][]

下面启动tomcat

进入到/usr/my/tomcat/bin

启动tomcat，命令 ./startup.sh

![70 13][]

出现tomcat started，然后进入linux的浏览器输入网址：localhost:8080,看看有没有看先tomcat页面

![70 14][]

![70 15][]

查看虚拟机的ip

![70 16][]

然后回到主机

在浏览器里输入192.168.37.130:8080无法进入tomcat页面。这是因为linux的防火墙关闭了80端口和8080端口。

可用如下链接里的方法进行处理。
