jar package details

You need to import the following package into the database. It's really slow to access their official website directly... I don't want to say anything. My version is version 5.2. Please pay attention to your version

#I packed all these jar packages into compressed packages
cas-server-support-jdbc-5.2.0.jar
cas-server-support-jdbc-authentication-5.2.0.jar
cas-server-support-jdbc-drivers-5.2.0.jar
mysql-connector-java-5.1.36.jar

Create database

-- Turn on remote access 
GRANT ALL PRIVILEGES ON *.*TO 'root'@'%' IDENTIFIED BY 'root' WITH GRANT OPTION;

-- Delete the database if it exists
DROP DATABASE IF EXISTS yellowcong;

-- Create database
CREATE DATABASE yellowcong;

-- Use database
USE yellowcong;

-- Create table
CREATE TABLE `yellowcong_users` (
  `id` INT(11) NOT NULL AUTO_INCREMENT,
  `age` INT(11) DEFAULT NULL,

  `password` VARCHAR(32) DEFAULT NULL,
  `user_name` VARCHAR(32) DEFAULT NULL,
  PRIMARY KEY (`id`)
) ENGINE=INNODB AUTO_INCREMENT=15 DEFAULT CHARSET=utf8;


-- insert data
INSERT INTO yellowcong_users

Database configuration

Note that we directly modify the cas/WEB-INF/classes directory under tomcat application.properties configuration file

Configuration database information, the following configuration, it is recommended that you directly copy one copy, and then modify it on the basis of the above
