Linux installs nodejs online and configures scheduled tasks

foreword

After the installation last redisnight, the reminder was invaded as a springboard machine, and I didn’t care about it at the time. There was nothing urgent and important on that machine, so I hung up two nodescheduled tasks, but this morning I found that the scheduled tasks were not triggered. The wget, curl, and other commands in the server nodeare all invalid. It seems that the server has been cleaned in depth, and even the scheduled tasks are gone.
