Speed UP WordPress site with Nginx cache

Think left and right, the last word solution is to use Nginx cache, the first article can refer to: Nginx configuration fastcgi cache. The advantage of fastcgi_cache is that the majority of users ’requests don’t get to affect back-end php-fpm, and send cached static pages directly, throwing various WordPress plugins at a speed of flash! In contrast, various plugins of WordPress still got to execute PHP, and it’s inevitable to access the database, which is weak!

Since the nginx cache is used, the web site runs smoothly, and there has never been a downtime. At an equivalent time, the CPU and memory usage of VPS have plummeted, and there’s no got to worry about the configuration of VPS anymore. I feel that ten times more traffic blogs can hold up!

Because nginx is as stable as a dog experience, now products that read more and write less for blogs are pushing nginx cache (fastcgi cache or proxy cache). insight of the likelihood of helping some netizens, the configuration file is posted for netizens’ reference (including SSL settings and gzip part):/etc/nginx/nginx.conf
