Having been using an installed version of mysql for some time without any problem, when I attempted to start the server recently it simply failed to recognise the command.

The installation is still there and I can see my databases in the filesystem. However, I cannot start the server. See the following steps, which include trying to re-add mysql to the $PATH or the bash profile, as advised in several other answers (although I don't believe this was necessary before).

pointcloud:~ james$ mysql.server start
-bash: mysql.server: command not found
pointcloud:~ james$ cd ../../usr/local/var
pointcloud:var james$ ls
cache       homebrew    log     mysql
pointcloud:var james$ cd mysql

pointcloud:mysql james$ echo $PATH
pointcloud:mysql james$ export PATH=/usr/local/var/mysql:${PATH}
pointcloud:mysql james$ echo $PATH
pointcloud:mysql james$ mysql.server start
-bash: mysql.server: command not found
pointcloud:mysql james$ 

Some of the other answers refer to a /bin or /support-files directory in the mysql directory. I don't seem to have these.

I'm not aware what has changed since I last started the server. I have installed a number of Homebrew and Python packages, but not anything to do with mysql, as far as I am aware.

Any assistance in restoring access to my DBs gratefully received.

Alternatively, if there is a way of re-installing Mysql while preserving and re-importing the existing DBs, this would be a possibility.

Installed system version: OSX 10.11.4 (15E65)


I believe my mysql version was installed under homebrew, but it was some time ago (2yrs +) when I was less proficient, and I'm unable to recall the details.

brew list does not include mysql, so that is not the case.

pointcloud:mysql james$ brew list
eigen       ilmbase     libpng      opencv      python      x264
ffmpeg      jpeg        libtiff     openexr     readline    xvid
gdbm        lame        numpy       openssl     sqlite

Searching for mysql binaries in the file system:

pointcloud:var james$ sudo find / -type f -name mysql

  • As per edit: I installed it over two years ago when much less proficient. I think it was probably homebrew but actually do not know. How would I establish this?

  • Then no, it's not under Homebrew after all.

  • There are no mysql directories in /usr/local/ only in /usr/local/var/ (see transcript in question). I have used macports in the past, but do not currently have it installed. I'm not familiar with the other methods.

  • Results in edit. Find is still running but hasn't output anything for ~10 minutes.

  • Edited to add more locations - all in backups. Does it look like Homebrew deleted mysql recently?

It appears, evidenced by the backups, that at some previous (recent) point, the Homebrew version of mysql was uninstalled, leaving the data intact.

Reinstalling with brew install mysql returned full functionality.
