First of all, thanks to The Disintegrated Life Chronicles for the recommendation.
There isn't much to say about free hosting, after all, it's free. Still, I’ll shamelessly mention that some free hosting offers a 50MB database, which is fine, while others only provide 100MB-300MB of disk space. Slightly larger installation packages can't fit. Some require completing various tasks and promotions step by step. The most expensive free option is not just about data, but also the time spent, etc.
LanDui Cloud, upon registering that day, found that it wasn't open; the interface indicated how many hours until it would be available. The next day at four o'clock, it opened for grabs. Following the process, I wasn't sure how many people were actually there. I applied for a virtual space from a telecom provider, asking if it was okay. It was from a domestic southern telecom provider, and since it was connected to Unicom, I agreed without hesitation.
After applying, I found that the control panel wasn't as smart as those on foreign servers; all operations were done via the web. Setting up WordPress generally takes a few minutes. All good. LanDui Cloud requires FTP, so I went to download FileZilla and Xftp8 (previously using Xshell with a free license felt fine too), both are comparable, and I probably haven't used other features.
Reasons for Failure#
Installation failed for several days.
This zip file extraction was something I had never seen before; whether it succeeded or failed could be checked in the logs, or by observing changes in the FTP directory.
I estimate that many years ago, I uploaded files already extracted, which was indeed slow, and it remains so now. But it's okay; I just wait and don’t need to keep watching.
Don’t fill in anything for the extraction path; otherwise, it will create nested directories. WordPress files cannot be placed in a directory named 'wordpress'; I discovered this after multiple failures by looking at the images. All files inside the WordPress directory must be copied directly to the root directory. This copying process takes a long time. Just keep waiting. The reason for failure has been found. It’s not a permission issue; it needs to be filed. The domain is already filed. The space also needs to be filed. Suddenly enlightened. This is a domestic server, okay. Withdraw.
