无法使用 Homebrew 在 MacOS Mojave 上安装 MySQL 5.7

Question

我正在尝试在 macOS Mojave 上使用 Homebrew 安装 MySQL 5.7，但是我收到以下错误：

[错误] 无法打开文件 '/var/log/mysql/error.log' 出错 日志记录：不允许操作 [错误] 中止

我已经尝试自己创建文件，因此 Homebrew 不需要创建它，但它仍然会抱怨。 /var/log 里面有这个

drwxrwxrwx 3 _mysql _mysql 96 20 Aug 21:25 mysql

在/var/log/mysql 里面我有这个：

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

（我手动将它们设置为 777 并归 mysql:mysql 所有）

这是完整的输出：

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

从 brew install 的输出来看，它看起来像是已安装。 似乎这是 /var/log/mysql/error.log 上的权限问题

尝试更改 /var/ 文件夹的权限
