一、今天需要使用到本地的Tomcat，结果在网上找了下教程，都是假的，都有问题，都没有经过测试，不负责任啊啊啊，坑爹坑爹。
Mac正确安装Tomcat的姿势
首先访问一下Tomcat的官网：
Tomcat官网 
想下载什么版本就点击什么版本
二、下面以Tomcat9为例，Mac和Linux的一定要下载tar.gz文件，其余的都有问题 
三、解压后，重命名文件夹 
四、通过终端进入到Tomcat的bin目录下

$ 五、启动Tomcat
./startup.sh~/Develop/Tomcat/tomcat9/bin ⌚ 19:16:31
$ ./startup.sh

Using CLASSPATH: /Users/wangdong/Develop/Tomcat/tomcat9/bin/bootstrap.jar:/Users/wangdong/Develop/Tomcat/tomcat9/bin/tomcat-juli.jar
Tomcat started.

$ 六、访问http://localhost:8080/ 
出现上述的界面，就证明成功了。
七、关闭Tomcat
./shutdown.sh~/Develop/Tomcat/tomcat9/bin ⌚ 19:17:23
$ ./shutdown.sh
