Tomcat介绍
Tomcat是Apache软件基金会(Apache software Foundation)的Jakarta项目中的一个核心项目，由Apache、Sun和其他一些公司及个人共同开发而成。
java程序写的网站用tomcat+jdk来运行
tomcat是一中间件，真正起作用的，解析脚本的是jdk
jdk(java development kit)是整个java的核心，它包含了java运行环境和一堆java相关的工具以及java基础库。
最主流的jdk为sun公司发布的jdk，除此之外，其实IBM公司也有发布JDK，CentOS上也可以用yum安装openjdk

安装jdk

http://www.oracle.com/technetwork/java/javase/downloads/jdk8-downloads-2133151.html

ctrl+alt+f打开xftp(双击就可下载到linux系统的/usr/src目录下)

cd /usr/local/src/
tar -zxvf jdk-8u161-linux-x64.gz
mv jdk1.8.0_161/ /usr/local/jdk1.8

vim /etc/profile  
JAVA_HOME=/usr/local/jdk1.8/
JAVA_BIN=/usr/local/jdk1.8/bin
JRE_HOME=/usr/local/jdk1.8/jre
PATH=$PATH:/usr/local/jdk1.8/bin:/usr/local/jdk1.8/jre/bin
CLASSPATH=/usr/local/jdk1.8/jre/lib:/usr/local/jdk1.8/lib:/usr/local/jdk1.8/jre/lib/charsets.jar

source /etc/profile
java -version
java version "1.8.0_161"
Java(TM) SE Runtime Environment (build 1.8.0_161-b12)
Java HotSpot(TM) 64-Bit Server VM (build 25.161-b12, mixed mode)

安装Tomcat

wget http://mirror.bit.edu.cn/apache/tomcat/tomcat-8/v8.5.28/bin/apache-tomcat-8.5.28.tar.gz
tar -zxvf apache-tomcat-8.5.28.tar.gz
mv apache-tomcat-8.5.28 /usr/local/tomcat

启动tomcat

/usr/local/tomcat/bin/startup.sh
Using CATALINA_BASE:   /usr/local/tomcat
Using CATALINA_HOME:   /usr/local/tomcat
Using CATALINA_TMPDIR: /usr/local/tomcat/temp
Using JRE_HOME:        /usr/local/jdk1.8
Using CLASSPATH:       /usr/local/tomcat/bin/bootstrap.jar:/usr/local/tomcat/bin/tomcat-juli.jar
Tomcat started.

/usr/local/tomcat/bin/startup.sh
netstat -tlnp|grep java

8080为提供web服务的端口
8005为管理端口
8009端口为第三方服务调用的端口，比如httpd和tomcat结合时会用到

关闭防火墙，在浏览器中访问192.168.221.20:8080

配置Tomcat监听80端口

vim /usr/local/tomcat/conf/server.xml  //将8080改为80
<Connector port="8080" protocol="HTTP/1.1"
               connectionTimeout="20000"
               redirectPort="8443" />

/etc/init.d/nginx stop
/usr/local/tomcat/bin/shutdown.sh;/usr/local/tomcat/bin/startup.sh
netstat -tlnp|grep java  //以下是查看到的内容
tcp6       0      0 :::80                   :::*                    LISTEN      43897/java

tcp6       0      0 :::8009                 :::*                    LISTEN      43897/java
