实践笔记_J2EE_Server_Tomcat_tomcat域名绑定_1_单域名绑定

                                                                  Tomcat域名绑定(1)单域名绑定

1. 测试环境说明

2.简单方式一:操作步骤

        预期的结果是: 通过www.slm.cn 直接访问到tomcat中的项目的首页

2.1 实现访问时用 域名 代替 localhost或ip

           2.1.1 修改host文件

A. 打开运行 输入 C:\WINDOWS\system32\drivers\etc

​

B.记事本打开host文件,添加域名映射

这里我用的是一个测试过还在外租售的域名 www.slm.cn (PS:不是我的)

#代表注释

以下面的方式映射:

127.0.0.1    www.slm.cn

​

​

2.1.2  保存host文件  访问

ps:

到目前为止已经完成了ip和域名的绑定,这时候我们通过www.slm.cn就能访问到本机了.

以tomcat为例访问项目,  现在的访问地址就是:   http://www.slm.cn:8080/项目名

但是这样端口和项目名还是暴露了,下面来解决这个问题

2.2  隐藏8080端口

这个很简单,就是将tomcat响应端口从8080端口修改为80端口

         2.2.1 操作步骤如下:

A.打开tomcat server.xml文件,找到下行代码:

<Connector port="8080" protocol="HTTP/1.1" connectionTimeout="20000" redirectPort="8443"  URIEncoding="UTF-8" />

B.将上述代码中的 8080 修改为  80   .如下:

<Connector port="80" protocol="HTTP/1.1" connectionTimeout="20000" redirectPort="8443"  URIEncoding="UTF-8" />

C.保存  server.xml文件

这时访问地址中的端口就隐藏成功了.访问地址就变成了:  http://www.slm.cn/项目名

但是项目名还是存在,所以接下来我们还要隐藏项目名.

  2.3  隐藏项目名

同样是修改server.xml文件.操作如下

 2.3.1 操作步骤:

A.打开server.xml,找到 host节点

​

B.将一个host节点中的localhost 全部改为www.slm.cn

并添加子节点:<Context path=”” docBase=”/项目名/” reloadable=”true” />

比如我的项目名叫WEBTEST   所以修改后就是:

<Host name="www.slm.com" appBase="webapps"unpackWARs="true" autoDeploy="true" xmlValidation="false" xmlNamespaceAware="false">
<Valve className="org.apache.catalina.valves.AccessLogValve" directory="logs"
               prefix="localhost_access_log." suffix=".txt"
               pattern="%h %l %u %t "%r" %s %b" />
<Context path="" docBase="/WEBTEST/" reloadable="true" ></Context>
</Host>

C.找到

<Engine name="Catalina" defaultHost="localhost">

将defaultHost 的值 localhost  更改为 www.slm.cn  如下:

<Engine name="Catalina" defaultHost="www.slm.cn">

  从这里可以看到,它其实是映射关系,所以HOST其实可以有多个,但默认的就只有一个.

                    这就为后面配置多个项目日共了便利.这里我们只设置单个项目的映射. 

2.3.2  完整的示例

以tomcat为服务器,www.slm.cn为访问域名 crm为项目名  ,那么完整修改后的server.xml如下

​

2.4  保存修改的server.xml文件  重启tomcat

3.测试

3.1 这个时候加端口号的这个访问就访问不到了:

​

3.2 我们访问域名: http://www.slm.cn  结果如下:

​

4.其它版本测试
