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

~/Develop/Tomcat/tomcat9/bin ⌚ 19:16:26
$ pwd
/Users/wangdong/Develop/Tomcat/tomcat9/bin

~/Develop/Tomcat/tomcat9/bin ⌚ 19:16:29
$ ls
bootstrap.jar                setclasspath.bat
catalina-tasks.xml           setclasspath.sh
catalina.bat                 shutdown.bat
catalina.sh                  shutdown.sh
ciphers.bat                  startup.bat
ciphers.sh                   startup.sh
commons-daemon-native.tar.gz tomcat-juli.jar
commons-daemon.jar           tomcat-native.tar.gz
configtest.bat               tool-wrapper.bat
configtest.sh                tool-wrapper.sh
daemon.sh                    version.bat
digest.bat                   version.sh
digest.sh

~/Develop/Tomcat/tomcat9/bin ⌚ 19:16:31
$ 

五、启动Tomcat

./startup.sh

~/Develop/Tomcat/tomcat9/bin ⌚ 19:16:31
$ ./startup.sh
Using CATALINA_BASE:   /Users/wangdong/Develop/Tomcat/tomcat9
Using CATALINA_HOME:   /Users/wangdong/Develop/Tomcat/tomcat9
Using CATALINA_TMPDIR: /Users/wangdong/Develop/Tomcat/tomcat9/temp
Using JRE_HOME:        /Library/Java/JavaVirtualMachines/jdk1.8.0_161.jdk/Contents/Home
Using CLASSPATH:       /Users/wangdong/Develop/Tomcat/tomcat9/bin/bootstrap.jar:/Users/wangdong/Develop/Tomcat/tomcat9/bin/tomcat-juli.jar
Tomcat started.

~/Develop/Tomcat/tomcat9/bin ⌚ 19:17:23
$ 

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
Using CATALINA_BASE:   /Users/wangdong/Develop/Tomcat/tomcat9
Using CATALINA_HOME:   /Users/wangdong/Develop/Tomcat/tomcat9
Using CATALINA_TMPDIR: /Users/wangdong/Develop/Tomcat/tomcat9/temp
Using JRE_HOME:        /Library/Java/JavaVirtualMachines/jdk1.8.0_161.jdk/Contents/Home
Using CLASSPATH:       /Users/wangdong/Develop/Tomcat/tomcat9/bin/bootstrap.jar:/Users/wangdong/Develop/Tomcat/tomcat9/bin/tomcat-juli.jar
