2、tomcat应用程序部署
部署（deploy）webapp的相关操作：
deploy：将webapp的源文件放置于目标目录、配置tomcat服务器能够基于context.xml文件中定义的路径来访问此webapp；将其特有的类通过class loader装载至tomcat：
有两种方式：
自动部署：auto deploy
手动部署：
(1) 冷部署：把webapp复制到指定位置，而后才启动tomcat；
(2) 热部署：在不停止tomcat的前提下进行的部署：
部署工具：manager app、ant脚本、tcd（Tomcat Client Deployer）等；
undeploy：反部署，停止webapp，并从tomcat实例上拆除其部署文件和部署名；
stop：停止，不再向用户提供服务；
start：启动处于“停止”状态的webapp；
redeploy：重新部署；
tomcat自带的应用程序：
manager app: webapp管理工具；
host manager: VHosts管理工具；
(1)手动创建一个测试应用程序
~]# cd /usr/local/tomcat/webapps/
webapps]# ls
docs examples host-manager manager ROOT
webapps]# mkdir myapp
webapps]# cd myapp/
myapp]# mkdir class lib WEB-INF META-INF
[root@localhost myapp]# ls
class lib META-INF WEB-INF
myapp]# vim index.jsp
myapp]# cat index.jsp
<%@ page language="java" %>
<%@ page import="java.util.*" %>
<html>
<head>
<title>JSP Test Page</title>
</head>
<body>
<% out.println("hello world");
%>
</body>
</html>
此时由于tomcat默认为热部署，所以网页已经可以正常访问
tomcat会默认把jsp网页编译成java语言
~]# cd /usr/local/tomcat/work/Catalina/localhost/myapp/org/apache/jsp/
jsp]# ls
index_jsp.class index_jsp.java
(2)tomcat自带的应用程序
提示用户在conf/tomcat-users.xml下进行配置
~]# cd /usr/local/tomcat/conf/
conf]# vim tomcat-users.xml
在<tomcat-users>下面添加
<role rolename="manager-gui"/>
<user username="tomcat" password="tomcat" roles="manager-gui"/>
重启tomcat服务

管理页面可以对web app进行部署，开启，关闭，reload，update
(3)部署一个商城app进行测试
商城app解压
~]# unzip shopxx-a5-Beta.zip
~]# ls
all.sql apache-tomcat-7.0.55.tar.gz shopxx-a5-Beta.zip 说明.htm
anaconda-ks.cfg jdk-7u79-linux-x64.rpm shopxx-v3.0-Beta
将文件mv至部署目录
~]# cd shopxx-v3.0-Beta/shopxx-3.0Beta/
shopxx-3.0Beta]# ls
admin favicon.ico install META-INF robots.txt upload
changelog.txt index.jsp license.html resources shopxx.txt WEB-INF
hopxx-3.0Beta]# ls install/
check_encoding.jsp css index.html install_demo.jsp js
check.jsp data index.jsp install_init.jsp sample
common.jsp images install_config.jsp install.jsp setting.jsp
shopxx-3.0Beta]# cd ..
shopxx-v3.0-Beta]# ls
shopxx-3.0Beta
shopxx-v3.0-Beta]# mv shopxx-3.0Beta/ /usr/local/tomcat/webapps/shopxx
此时网站已经可以正常访问
配置后台数据库
~]# yum -y install mariadb-server
~]# systemctl start mariadb.service
~]# mysql

安装提示删除install目录，并重启
~]# cd /usr/local/tomcat/
tomcat]# ls
bin conf lib LICENSE logs NOTICE RELEASE-NOTES RUNNING.txt temp webapps work
tomcat]# cd webapps/
webapps]# ls
docs examples host-manager manager myapp ROOT shopxx
webapps]# cd shopxx/
shopxx]# ls
admin changelog.txt index.html license.html product robots.txt sitemap WEB-INF
article favicon.ico install META-INF resources shopxx.txt upload
shopxx]# mv install/ install.bak
此时我的tomcat管理界面上已经有shopxx应用，进行reload操作，或者使用catalina.sh进行stop再start
此时网站部署完成
