MacPorts + MySQL5.7

MySQL

プライベートな環境を久々に更新しようと思ってやったら思いの外はまった。
仕事は homebrew だけどプライベートマシンは MacPorts を使ってる。

Python3.6.0, MySQL5.6 だったので Python3.6.1, MySQL5.7.17 にするかとports upgrade outdated して、MySQL を新規にインストールしようとしたらどハマりしたのでメモ。


入れる先。

  • /opt/local/var/run/mysql57
  • /opt/local/var/db/mysql57
  • /opt/local/var/log/mysql57


`$ sudo -u _mysql /opt/local/lib/mysql57/bin/mysqld --initialize` をするとに権限がないと怒られるので、`--tmpdir=/tmp` をつける。

`$ sudo /opt/local/lib/mysql57/bin/mysqld --initialize --user=_mysql --tmpdir=/tmp`


これでログに色々非推奨になったものとかが出てくるので、まずは my.cnf をきれいにする。

 innodb_large_prefix
-innodb_file_format=Barracuda
-sql_mode="NO_ENGINE_SUBSTITUTION,STRICT_TRANS_TABLES"
+sql_mode="NO_ENGINE_SUBSTITUTION,STRICT_TRANS_TABLES,NO_ZERO_DATE,NO_ZERO_IN_DATE,ERROR_FOR_DIVISION_BY_ZERO,NO_AUTO_CREATE_USER"
+explicit_defaults_for_timestamp=1

これで非推奨な警告らしいものは消えた。


起動したはずだからログに出てるパスワードを使って cli から接続してみると、

Error: Can't connect to local MySQL server through socket '/opt/local/var/run/mysql57/mysqld.sock' (2)

が出た。


/opt/local/var/run/mysql57 に mysql.sock を touch し chown _mysql しておく。

それでもまだ同じのが出るので、ググったら、
`secure-file-priv` とやらを設定する必要がありそうだ。

+secure-file-priv=/opt/local/var/db/mysql57/files

/opt/local/var/db/mysql57/files を 770 に設定。


再度実行。
