There are red dots, rather than green dots, next to "Active Instance" in the preference pane. Image here. When I click "Start MySQL Server" the lights flash green very briefly before turning red again. In other install tutorials (e.g. this), this doesn't happen.
However, when I try to use command line to start the server, with sudo launchctl load -F /Library/LaunchDaemons/com.oracle.oss.mysql.mysqld.plist I get the line /Library/LaunchDaemons/com.oracle.oss.mysql.mysqld.plist: service already loaded Load failed: 37: Operation already in progress. So it seems like some parts are already loaded.
When I try to launch MySQL (with mysql -u root -p), I get the error:
dyld: Symbol not found: __ZTTNSt3__118basic_stringstreamIcNS_11char_traitsIcEENS_9allocatorIcEEEE Referenced from: /usr/local/mysql/bin/mysql (which was built for Mac OS X 12.0) Expected in: /usr/lib/libc++.1.dylib in /usr/local/mysql/bin/mysql Abort trap: 6
I get the same error when I try to do mysql --version.
Previously, I was getting the error -bash: mysql: command not found, but then I followed the suggestion here and added the path export PATH=$PATH:/usr/local/mysql/bin. (Note that I still get the -bash: mysql.server: command not found when I try mysql.server start, so I don't know if the new path export fixed the problem altogether.) I re-installed MySQL from the DMG but still getting this error.
Additional information that may be relevant:
-I am on Mac OS X 11.6.5.
-I have uninstalled/re-installed MySQL several times
-I copied my.cnf and put it in the "Configuration File" spot in preferences, with the file path: /private/etc/my.cnf. This is also a part where it's possible I went wrong, since I don't exactly know what I'm doing; I just tried to follow directions from here, here and used the actual code from here. I also tried putting the my.cnf file in /usr/local/mysql, as some other sources seem to suggest. This did not work either.
Solved: what I needed to do was uninstall MySQL and instead download an archived version of it--8.0.24 instead of the latest, 8.0.32, because it hadn't been compatible with my Mac version.
