以下是在Ubuntu上安装配置Tomcat的步骤：
sudo apt update，sudo apt upgrade。sudo apt install openjdk-11-jdk，安装后用java -version验证。wget https://downloads.apache.org/tomcat/tomcat-10/v10.0.27/bin/apache-tomcat-10.0.27.tar.gz，然后tar xzvf apache-tomcat-10.0.27.tar.gz -C /opt。~/.bashrc或/etc/profile，添加export CATALINA_HOME=/opt/apache-tomcat-10.0.27和export PATH=$PATH:$CATALINA_HOME/bin，再执行source ~/.bashrc。/opt/apache-tomcat-10.0.27/bin，执行./startup.sh，可通过http://localhost:8080验证。sudo ufw allow 8080/tcp。
