In addition to the hardware considerations listed previously, here are some additional points to consider:
- Verifying needed OS libraries: MongoDB relies upon various OSÂ libraries. One very common example is the need for an up-to-date version of the OpenSSL library if you plan to configure MongoDB to use Secure Sockets Layer/Transport Layer Security (SSL/TLS) in its communications.
- Clock synchronization: As any DevOp is aware, internal computer clocks are notorious for their drift. Accordingly, many schemes have been used over the years to keep computer clocks in sync. The most prevalent technology used today is the Network Time Protocol (NTP). Servers run an internal daemon (or service) that makes occasional checks to one or more primary NTP servers. An internal drift algorithm is used to make micro-adjustments to the server clocks such that the need to check with an NTP server declines over time, as the NTP daemon running locally learns to adjust...
