How can I solve high CPU usage, 100%, all the time for Ubuntu 14.04?

I’m using $ 10 / mo DigitalOcean package which have 1 GM ram, 1 Core processor, 30 GB SSD disk running Ubuntu 14.04, Apache, Mysql and Wordpress latest version.

I didnt change any configuration file on system but sometimes I’m seeing 100% CPU and cant access my site on browser.

PS: Power off/boot cant solve the problem.

Just migrate from Apache to Nginx …

You will also need this to have Wordpress work perfectly with Nginx.

It’s a little bit of work, but worth it…

Have some coffee tonight and put in work!! Thank me later!!! All the best.
