Imagine a situation: you have a static ip and you do a lot and do a lot of time editing the site. At the same time, you still need to monitor, periodically, the logs for errors in queries, or for vulnerability scans. And the presence of a large number of records with your IP makes it difficult to view logs.

With the help of a conditional entry that is available in nginx, starting with version 1.7.0, we can check the visitor's ip and not record it in the log files. Indeed, why do this if logging your ip is not necessary?

Caching data in RAM via Redis is one of the methods to speed up the site. This storage is highly efficient and can be used to cache not only sites, but also sessions, as well as a non-relational database.

While some put php 5.3 , getting it out of the grave, I decided not to lag behind the whole planet, where the sites are translated to the seventh version of php, which is so much praised on the Internet, including high speed, and installed it from the DotDeb repository today. I must say, the increase in speed is really noticeable. My websites and WordPress, and MODX began to fly yet. :) That's how I did the migration.

HTTP / 2 is the second version of the http network protocol, which includes many different improvements. These include multiplexing requests (all requests can be processed in parallel), increased performance, header compression, etc.

HTTP / 2 has replaced SPDY, which has been discontinued.

Nginx supports the http / 2 protocol, starting with version 1.9.5. However, only version 1.6.2 is present in the stable release of Debian Jessie. Therefore, we will connect the backports repository to upgrade nginx to 1.9.10.
