LNMP parameter optimization (without comments) and lnmp Optimization

Introduction:

PHP FastCGI advantages

1. PHP scripts run faster. The PHP interpreter program is loaded into the memory instead of reading from the memory every time it is needed, which greatly improves the performance of the website running by scripts.
2. Fewer system resources are required. Because the server no longer loads the PHP interpreter every time it needs it, it can increase the transmission speed of the site much without increasing the CPU burden.
3. Do not change the existing code. The program running on Apache + PHP can be applied to PHP FastCGI without modification.
