We're open now. Drape Fit is no longer available...

I'd like to make some of my private ex-projects public now.

😱 How? Why?

📌 drapefit-new-trial-mern

🎯 MongoDB LogRotate on Ubuntu 20.04

We sometimes experience that the MongoDB server would get down on the EC2 test instance unexpectedly.

Trying to find out what might let the DB server down, I've noticed that the MongoDB log file's size is extremely large, even bigger than 100MB.

Since stdin & stdout processes such as logging are really memory-costing, it would be certainly an overload for the EC2 test instance of small tier.

To solve this issue, I've introduced the LogRotate function of Ubuntu to the MongoDB server.

$ sudo nano /etc/logrotate.d/mongod
Enter fullscreen mode Exit fullscreen mode

Copy and paste the following content:

/var/log/mongodb/*.log {
    daily
    rotate 30
    compress
    dateext
    missingok
    notifempty
    sharedscripts
    postrotate
        /bin/kill -SIGUSR1 `cat /var/lib/mongodb/mongod.lock 2> /dev/null` 2> /dev/null || true
        systemctl restart mongod
    endscript
}
Enter fullscreen mode Exit fullscreen mode

To test the configuration running:

$ logrotate -f -v /etc/logrotate.d/mongod
Enter fullscreen mode Exit fullscreen mode
