Yesterday, I restarted because I wanted to set up a mail server by myself and install Redis as an auxiliary environment.
However, the installation of Redis failed. Repairing the Baota panel was ineffective, and updating the Baota panel was also ineffective.
After restarting the server, the CPU usage has been high, whereas on normal days my CPU usage is 0.
This made me feel uneasy. Redis still couldn't be installed, and I had a hard time finding other solutions.
Because in the past, when I was messing with the server, there were situations where it couldn't be opened. Please see: https://k7blog.com/88.html
So I decided to reinstall after waking up and shut down the server directly.
The next day, I backed up the data and reinstalled the server. (This service provider's server reinstallation is particularly slow.)
Then I installed Baota, but downloading files was also very slow, and the compilation environment was also very slow.
In short, everything was slow. After successfully installing, installing LNMP was also very slow. After finally installing it, some functions of Baota were abnormal.
The situation of high CPU usage persisted, so I reinstalled again.
It was another long wait for installation, and then when installing the mail server plugin, not only was the download slow, but after waiting for it to complete, it threw an error.
I tried to fix it according to the error message, but it still didn't work. I gave up, and the CPU usage issue still exists.
I thought about changing to another server, but deploying this server was also very slow. If it weren't for having a few hundred dollars in this service provider account, I would have switched providers directly.
Today, I wasted too much time on downloading and compiling the environment. It was a frustrating day...
