第一步：修改 $TOMCAT_HOME\conf 下的server.xml文件

1.复制节点 ，粘贴新增节点

2.删除掉新增节点下的<Connector port="8009" protocol="AJP/1.3" redirectPort="8443" />节点

3.新增Service节点的name属性修改为Catalina1

4.新增Service节点的Connector节点port属性修改为8081（根据机器配置未占用端口）

5.新增Service节点的Engine节点的name修改为Catalina1

6.新增Service节点的Engine节点的Host节点appBase属性修改为webapps1

7.Engine节点下的Host节点中添加：<context docbase path reloadable source></context>，例子中helloMVC是项目名。(解决了我访问新加项目中jsp等页面文件404的问题)

不用项目名称访问：把中的contex中的path属性设为“”，端口改为80，可直接ip或域名访问。

第二步：$TOMCAT_HOME 路径下新建文件夹webapps1，里面放要发布的项目 .war文件

第三步： 复制$TOMCAT_HOME\confi目录下的Catalina生成副本 ，并命名为Catalina1

第四步：启动：/opt/tomcat/bin/catalina.sh

参考自： 

关于部署多个项目

关于访问不用项目名

$TOMCAT_HOME 路径下新建文件夹webapps1，里面放要发布的项目 .war文件

下面附上我的server.xml 例子，其中Catalina1是域名访问，不用项目名访问。
