    ExecReload=/bin/kill -s HUP MAINPID

    PrivateTmp=true

    [Install]

    WantedBy=multi-user.target

  • Use the tomcat.service command:

  • http://ip:8080/ Check whether the verification is successful

Mysql installation and configuration

  • Download the YUM source RPM package from the MySQL official website

  • Yum localinstall xxx. RPM: Use the installation source
