1. Download and install Tomcat
1. Download
First, open the Tomcat official website: https://tomcat.apache.org , select the version you need under the Download column, here select the latest Tomcat 10.
Then select the code package, here select the zip package to download.
2. Install
After downloading, decompress it, and then copy the decompressed folder to the location you need. It is recommended to copy it to the Library directory under the user name directory or create a new directory for storage. I create a new Environment directory and copy apache-tomcat-10.0.27 The folder is copied here. At this time, the path of the folder is /Users/(Mac user name)/Environment/apache-tomcat-10.0.27.
2. Environment configuration
Click on the launch pad, enter the following command, find the terminal and enter the bin directory of Tomcat
% cd /Users/（Mac用户名）/Environment/apache-tomcat-10.0.27/bin
Then enter the command ls to see the file structure in the bin directory:
1. Start Tomcat
Run startup.sh in the bin directory to start Tomcat
% ./startup.sh
It is found that the prompt Permission denied (denied access), and then use the permission management command chmod to modify the execution permission of the .sh file
% chmod u+x *.sh
Run startup.sh again, and find that Tomcat started is displayed, and Tomcat is successfully started.
Open the Safari browser, enter http://localhost:8080 in the address bar, and you can see the Tomcat prompt page.
2. Close Tomcat
Run the shutdown command in the bin directory to stop the server.
% ./shutdown.sh
After the prompt as shown in the figure appears, it means that the Tomcat server has stopped running. Go back to the Safari browser to refresh the port 8080 of localhost, and find that the prompt page has disappeared.
3. View Tomcat version information
Run version.sh in the bin directory to view the relevant version information of Tomcat.
% ./version.sh

2.chmod is a permission management command in Linux, and its full English name is "change the permissions mode of a file". Its syntax is
chmod[{ugoa}{±=}{rwx}][file or directory]
| uncle | ±= | rwx |
|---|---|---|
| u: owner | +: increase permissions | r: Read permission |
| g: Belonging group | -: Reduce permissions | w: Write permission |
| o: others | =: grant the given permission, cancel all other permissions | x: eXecute execution permission |
| a: everyone |
Therefore, chmod u+x *.sh means to increase the execution permission to the owners of all sh files in the current directory.
