一、安装JAVA环境

1.安装JAVA

mkdir -p /usr/local/java

下载jdk1.7.0_67.tar.gz包，并解压到

tar xf jdk1.7.0_67.tar.gz -C  /usr/local/java

2.配置环境变量

cd /etc/profile.d
vim java.sh
export JAVA_HOME=/usr/local/java/jdk1.7.0_67
export CLASS_PATH="$JAVA_HOME/lib:$JAVA_HOME/jre/lib"
export PATH=$PATH:$JAVA_HOME/bin

让配置生效：

source /etc/profile

安装与配置比较简单。执行java -version命令，出现类似界面表示成功。

二、安装Tomcat环境

1、下载安装包

wget http://mirror.bit.edu.cn/apache/tomcat/tomcat-8/v8.5.31/bin/apache-tomcat-8.5.31.tar.gz
tar xf apache-tomcat-8.5.31.tar.gz -C /usr/local/
cd /usr/local/
ln -sv apache-tomcat-8.5.31 tomcat

2.配置环境变量

vim /etc/profile.d/tomcat.sh

CATALINA_BASE=/usr/local/tomcat
PATH=$CATALINA_BASE/bin:$PATH
export PATH CATALINA_BASE

让配置生效：

source /etc/profile.d/tomcat.sh

3.查看tomcat版本状态

catalina.sh version

三、配置tomcat

1.配置server.xml

/usr/local/tomcat/conf/server.xml （修改配置文件里面的端口号，修改为自己想要开放的端口）

<Connector port="80" protocol="HTTP/1.1" //默认端口为8080，改为自己想要开放的端口
connectionTimeout="20000"
redirectPort="8443" />

2.配置tomcat-users.xml和webapps/manager/META-INF/context.xml和webapps/host-manager/META-INF/context.xml

tomcat有manager-gui的管理页面，想要使用必须配置管理用户，不使用可以跳过此步。

<role rolename="manager-gui"/> //指定用户可以使用的接口为manager-gui
<user username="tomcat" password="tomcat" roles="manager-gui"/> //用户名和密码为tomcat，在manager-gui接口使用

cat  webapps/manager/META-INF/context.xml

</Context>

四、测试

1.创建测试页面

/usr/local/tomcat/webapps/test/index.jsp

<%@ page language="java" %>
<%@ page import="java.util.*" %>
<html>
<head>
<title>test</title>
</head>
<body>
<%
out.println("Hello World!"); //嵌入java语言
%>
</body>
</html>

2.启动测试

catalina.sh start

用浏览器打开页面。

a、主页

b、Server Status

c、HostManager

d、最后访问应用，Hellow World！

至此，tomcat的测试环境搭建完成。
