[linuxcar1]

so i tried a week now to install zm but with no luck.
i am new with linux and dont know how to work with it yet but zoneminder is importend for my security camera(s)

What is tried is this:

But without succes.

Then i tried the some instructions from youtube video's
- https://www.youtube.com/watch?v=Spr-JD2bEbc

also no succes and my whole pc crasht and must install linux all over again.

then they told me to install this scripts
https://wiki.zoneminder.com/Shell_scrip ... 28MySQL.29

So i have trtied some random commands:
# systemctl restart mysql

Failed to restart mysql.service: Unit mysql.service is masked.

# service mysqld start

Failed to start mysqld.service: Unit mysqld.service not found.

# sudo systemctl unmask mysql.service

Removed symlink /etc/systemd/system/mysql.service

# systemctl restart mysql

Job for mysql.service failed because the control process exited with error code. See "systemctl status mysql.service" and "journalctl -xe" for details.
