无法使用Homebrew在MacOS Mojave上安装MySQL 5.7

Question

I am trying to install MySQL 5.7 with Homebrew on macOS Mojave, however I am getting the following error:

[ERROR] Could not open file '/var/log/mysql/error.log' for error logging: Operation not permitted [ERROR] Aborting

I have tried to create the file myself so Homebrew doesn't need to create it, but it still complains. /var/log has this in it

drwxrwxrwx 3 _mysql _mysql 96 20 Aug 21:25 mysql

and inside /var/log/mysql I have this:

-rwxrwxrwx 1 _mysql _mysql 0 20 Aug 21:25 error.log

(I manually set them to 777 and owned by mysql:mysql )

This is the full output:

A CA file has been bootstrapped using certificates from the SystemRoots
keychain. To add additional certificates (e.g. the certificates added in
the System keychain), place .pem files in
  /usr/local/etc/openssl/certs

and run
  /usr/local/opt/openssl/bin/c_rehash

openssl is keg-only, which means it was not symlinked into /usr/local,
because Apple has deprecated use of OpenSSL in favor of its own TLS and crypto libraries.

If you need to have openssl first in your PATH run:
  echo 'export PATH="/usr/local/opt/openssl/bin:$PATH"' >> ~/.bash_profile

For compilers to find openssl you may need to set:
  export LDFLAGS="-L/usr/local/opt/openssl/lib"
  export CPPFLAGS="-I/usr/local/opt/openssl/include"

Warning: The post-install step did not complete successfully
You can try again using `brew postinstall mysql@5.7`
==> Caveats
We've installed your MySQL database without a root password. To secure it run:
    mysql_secure_installation

MySQL is configured to only allow connections from localhost by default

To connect run:
    mysql -uroot

A "/etc/my.cnf" from another install may interfere with a Homebrew-built
server starting up correctly.

mysql@5.7 is keg-only, which means it was not symlinked into /usr/local,
because this is an alternate version of another formula.

If you need to have mysql@5.7 first in your PATH run:
  echo 'export PATH="/usr/local/opt/mysql@5.7/bin:$PATH"' >> ~/.bash_profile

For compilers to find mysql@5.7 you may need to set:
  export LDFLAGS="-L/usr/local/opt/mysql@5.7/lib"
  export CPPFLAGS="-I/usr/local/opt/mysql@5.7/include"


To have launchd start mysql@5.7 now and restart at login:
  brew services start mysql@5.7
Or, if you don't want/need a background service you can just run:
  /usr/local/opt/mysql@5.7/bin/mysql.server start

Answer 1

from the output of brew install, it looks like it was installed. it seems like it's a permission issue on /var/log/mysql/error.log

try changing the permission on /var/ folder
