Nginx and PHP-FPM for heavy load wordpress web server with high traffic 2000+ concurrent connections.
To make it to read short I will not be describing all the time I lost during last half year trying to find out the “right settings” for the high traffic WordPress web server running I was responsible for, and this was on the top of my primary job, and that’s why it took so much time of blind testing and playing parameters with live production server, and as you understand I have no ability to make sharp actions and have long downtime, while having only 30-40 minutes per day. Anyway I found all needed information, tested everything, it works, I’m happy.
Being IT (not a developer) I was always searching for simple easy tune-able and effective solutions. First web server I've managed was IIS 2.0 on Windows NT 4.0 Server. In 1998 it was more than enough for University web page and I was as happy as Larry, and was very proud of my skills thinking that it is rock solid solution for ages 🙂
The year 2002 was my graduation, the university admin who replaced me on this post was surprised to see IIS 4.0, and as he said that I had a MustDie! solution. He was the one who showed me Apache, which I hated since my first contact due to I was complete fool in Linux, and continued to use IIS for any tasks in any job places where it was requested until 2005 when I've tasted the power of Linux as a file server and as a proxy server. I was stubbornly continue to use IIS until I've met a demanding PHP developer appeared in the company I work and he almost ate my brain insisting to move company server to APACHE. Yes! that's appeared to be amazing, while I've was quite fluent in Linux and had perfect back server where I've played a lot with apache, and thanks Lance he thought me all he knew about Apache, I've completely abandoned IIS 6.5 and became LAMP guy.
