1.Tomcat简介

• Tomcat和Nginx、Apache(http)、Web服务器一样，具有处理HTML面的功能，不过tomcat处理静态HTML能力不如nginx服务器

• 使用方案：

  nginx和tomcat配合，nginx处理静态，tomcat处理动态程序

[root@localhost ~]# cd /usr/local
[root@localhost local]# mv jdk-8u191-linux-x64.tar.gz java
#配置环境变量
[root@localhost ~]# vim /etc/profile.d/jdk.sh
JAVA_HOME=/usr/local/java
PATH=$PATH:$JAVA_HOME/bin
export JAVA_HOME PATH
#检测JDK是否安装成功
[root@localhost ~]# source /etc/profile.d/jdk.sh
[root@localhost ~]# java -version
java version "1.8.0_211"
Java(TM) SE Runtime Environment (build 1.8.0_211-b12)
