手元にある古い MacBookAir に開発環境を用意したい。まず DB として MySQL を使おうと思って設定しようとしたときの顛末をメモ。
#環境
$ sw_vers
ProductName: Mac OS X
ProductVersion: 10.12.6
BuildVersion: 16G29
#作業手順
$ which mysql
$
MySQLが入ってない。brew ってので入れるらしい。
$ which brew
/usr/local/bin/brew
$ brew install mysql
Error: Could not create /usr/local/Cellar
Check you have permission to write to /usr/local
利用アカウントでは /usr/local にパーミッションがない、らしい。
root で実行するために sudo を使ってみる。
$ sudo brew install mysql

Error: Cowardly refusing to `sudo brew install`
You can use brew with sudo, but only if the brew executable is owned by root.
However, this is both not recommended and completely unsupported so do so at
your own risk.
root でインストールするとか危ないやんかと諭される。
わかんないのでググる。以下を参考にする。
brew doctor をするといいらしい。
$ brew doctor
Please note that these warnings are just used to help the Homebrew maintainers
with debugging if you file an issue. If everything you use Homebrew for is
working fine: please don't worry and just ignore them. Thanks!
Warning: The /usr/local directory is not writable.
Even if this directory was writable when you installed Homebrew, other
software may change permissions on this directory. Some versions of the
"InstantOn" component of Airfoil are known to do this.
You should probably change the ownership and permissions of /usr/local
back to your user account.
Warning: Your Homebrew is outdated.
You haven't updated for at least 24 hours. This is a long time in brewland!
To update Homebrew, run `brew update`.
他のソフトがパーミッション変えたみたいよ、とか Homebrew が古いよはよ update しろや、と詰られる。
素直に update する。
$ brew update
warning: unable to unlink .yardopts: Permission denied
warning: unable to unlink CONTRIBUTING.md: Permission denied
warning: unable to unlink SUPPORTERS.md: Permission denied
fatal: cannot create directory at '.github': Permission denied
Error: Failure while executing: git pull -q origin refs/heads/master:refs/remotes/origin/master
あ？とりあえず git pull できんよ、と。
わかんないのでググる（2回目）。以下を参考にする。
git のデータが汚れている？らしいので強制的にきれいにします。
$ git reset --hard && git clean -df
HEAD is now at 8f69a54 Mention homebrew-go-resources in cookbook
で、再び brew update する。
$ brew update
Error: /usr/local is not writable. You should change the
ownership and permissions of /usr/local back to your
user account:
sudo chown -R $(whoami) /usr/local
メッセージが変わった。対象dir のオーナーを変更しろとおっしゃる。
$ whoami
hoge
$ sudo chown -R hoge /usr/local
$ brew update
Already up-to-date.
ふう。ようやく brew の設定が終わった。MySQL を入れる。

==> Caveats
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
This formula 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 this software first in your PATH run:
echo 'export PATH="/usr/local/opt/openssl/bin:$PATH"' >> ~/.bash_profile
For compilers to find this software you may need to set:
LDFLAGS: -L/usr/local/opt/openssl/lib
CPPFLAGS: -I/usr/local/opt/openssl/include

==> 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
To have launchd start mysql now and restart at login:
brew services start mysql
Or, if you don't want/need a background service you can just run:
mysql.server start

感想
意外と引っかかったけれど、ググルとどうにでもなるのでインターネット環境って凄いなと思いました。
