Solve the problem of "Service Unavailable" 503 on the website and pagoda panel

Snail met a netizen yesterday who told me that his website and server could not be opened and needed to be solved. I asked what the problem was at first. He said that there was a 503 error after opening it, so when I saw it, it showed "Service Unavailable" \\" error message. This problem may be caused by a process in the server WEB environment being stuck or the disk may be full. Let’s take a look.

This is an error when seeing his website open.

Check the hard disk condition and it turned out that the problem was caused by the disk being full. Then clean up his unnecessary data.

My operation is to delete the useless backup data, and then I can see that a lot of space is saved. Then restart APACHE. His server is built with Pagoda panel and uses LAMP, so I just restart apache. Then the website can be accessed normally.
