Introduction to the Learning System

The Xuezhisi open source examination system is a java + vue examination system that does not separate the front and back ends. The main advantages are simple and fast development and deployment, friendly interface design, and clear code structure. Supports web and WeChat applets, covering devices such as PCs and mobile phones. Supports multiple deployment methods: integrated deployment, front-end and back-end separation deployment, and docker deployment.

Deploy java environment

#Prepare the environment
yum -y install vim wget lrzsz
#Upload jdk package
#Extract and install to the specified directory
[root@localhost ~]# tar -xf jdk-8u211-linux-x64.tar.gz -C /usr/local
[root@localhost ~]# mv /usr/local/jdk1.8.0_211/ /usr/local/java
#Modify system environment variables
[root@localhost ~]# vim /etc/profile
JAVA_HOME=/usr/local/java
PATH=$JAVA_HOME/bin:$PATH
#Reload environment variables
[root@localhost ~]# source /etc/profile
#Check whether the java environment is configured successfully
[root@localhost ~]# java -version
java version "1.8.0_211"
Java(TM) SE Runtime Environment (build 1.8.0_211-b12)
Java HotSpot(TM) 64-Bit Server VM (build 25.211-b12, mixed mode)

Install and configure mysql

#Install MySQL and change password
[root@localhost ~]# yum -y install mysql-server
[root@localhost ~]# systemctl start mysqld
[root@localhost ~]# grep pass /var/log/mysqld.log
