下载tomcat

这里以版本10.0.22为例

解压存至本地另存为apache-tomcat-10.0.22，放在你想存放的目录里面，我这里以目录/Users/yourusername/apache-tomcat-10.0.22为例子

打开Terminal（终端）,进入apache-tomcat所在目录

cd /Users/yourusername/apache-tomcat-10.0.22

给bin下的*.sh文件添加可执行权限

sudo chmod 755 ./bin/*.sh

进入bin目录

cd bin

查看tomcat版本,操作系统版本，jdk版本等信息

./version.sh

启动服务

./startup.sh

浏览器输入http://localhost:8080即可查看效果

接下来配置站点

参考apache-tomcat-10.0.22\conf文件夹里面的server.xml配置文件里面的

<Service name="Catalina"></Service>配置项即可

原始server.xml文件

自定义Service

             </Host>
        </Engine>
    </Service>

设置本地hosts

127.0.0.1	localhost2

在apache-tomcat-10.0.22目录下创建myapps/demo1目录，再增加index.jsp文件

index.jsp文件内容如下

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <meta name="viewport" content="width=device-width, initial-scale=1.0">
    <meta http-equiv="X-UA-Compatible" content="ie=edge">
    <title>jsp</title>
</head>
<body>
    hello tomcat!
</body>
</html>

命令行重启tomcat

./shutdown.sh
./startup.sh

浏览器输入http://localhost2:8080/demo1即可查看效果

可以在目录创建其他项目目录如demo2,demo3等等，这种方式是共用同一个域名(同一Host name)下的多个子项目，对应就是

http://localhost2:8080/demo2

http://localhost2:8080/demo3

方式二：不同域名(多个Host name)下的项目

设置本地hosts

127.0.0.1	demo1.cn

修改server.xml文件Server节点

   <Service name="Catalina">
       
     <Connector port="8080" protocol="HTTP/1.1"
                connectionTimeout="20000"
                redirectPort="8443" />
                
     <Engine name="Catalina" defaultHost="localhost">
         
       <Realm className="org.apache.catalina.realm.LockOutRealm">
           
         <Realm className="org.apache.catalina.realm.UserDatabaseRealm"
                resourceName="UserDatabase"/>
       </Realm>

       <Host name="demo1.cn" appBase=""
             unpackWARs="true" autoDeploy="true">
             <!--需要有context配置-->
             <Context docBase="myapps/demo1" path="/" reloadable="true" />
         <Valve className="org.apache.catalina.valves.AccessLogValve" directory="logs"
                prefix="localhost_access_log" suffix=".txt"
                pattern="%h %l %u %t &quot;%r&quot; %s %b" />

       </Host>
     </Engine>
   </Service>

重启tomcat，浏览器输入http://test1.cn:8080/浏览效果

编写重启tomcat的脚本restart.sh，内容如下

#!/bin/sh

sh ./shutdown.sh
sh ./startup.sh

授权

sudo chmod 755 ./restart.sh

注意事项：

autoDeploy：为true时表示自动部署；

这时.war文件不能在tomcat运行时删除，否则会删除自动解压的工程目录；可以在停止tomcat后再删除.war文件。
