インストール†[edit]

• mysql55-serverのアンインストール

  sudo port uninstall mysql55-server

• mysql8-serverのインストール

• 以下の警告が表示される(無視してOK?)

  Warning: -----------------------------------------------------------------------
  Warning: The port 'mysql8' uses the cxx11 PortGroup which is deprecated.
  Warning: Please instead specify the required c++ standard directly using
  Warning:     compiler.cxx_standard  2011
  Warning: replacing 2011 with newer standards (e.g. 2014, 2017) as required.

  --->  Some of the ports you installed have notes:
    mysql8 has the following notes:
      On activation if no /opt/local/etc/mysql8/my.cnf file exists one
      will be created which loads
      /opt/local/etc/mysql8/macports-default.cnf.
  
      If a /opt/local/etc/mysql8/my.cnf file exists MacPorts does not
      touch it and any changes you make to /opt/local/etc/mysql8/my.cnf
      will be preserved (e.g., during port upgrades, deactivations or
      activations). /opt/local/etc/mysql8/my.cnf is a good place to
      customize your mysql8 installation.
  
      Any changes made to /opt/local/etc/mysql8/macports-default.cnf
      will be lost during port upgrades, deactivations or activations so you
      are advised to not make changes here. Currently
      /opt/local/etc/mysql8/macports-default.cnf contains only one
      directive; to disable networking. With disabled networking it is
      possible to install and have running all the MacPorts mysql ports
      simultaneously.
  
      To set mysql8 as your preferred version of MySQL, use `port select`,
      as follows:
  
      $ sudo port select mysql mysql8
    mysql8-server has the following notes:
      If this is a new install you might want to run:
  
      $ sudo /opt/local/lib/mysql8/bin/mysqld --initialize --user=_mysql
      $ sudo port load mysql8-server
      $ /opt/local/lib/mysql8/bin/mysql_secure_installation
  
      The first command creates the necessary files for the MySQL database service.
      (Remember to make a note of the auto-generated root password from this step.)
      The second command starts the MySQL service.
      The last command helps to improve the security of your running MySQL instance.
  
      Once enabled, the MySQL logs can be found in:
      /opt/local/var/log/mysql8
  

• 要するに以下を実行する。最初にmy.cnfの設定か。sudoだとエラーがでたのでrootになってから実行した方が良いかも。

      $ sudo /opt/local/lib/mysql8/bin/mysqld --initialize --user=_mysql
      $ sudo port load mysql8-server
      $ /opt/local/lib/mysql8/bin/mysql_secure_installation
  

設定†[edit]

my.cnfの編集†[edit]

• 以下の内容におきかえ。デフォルトはネットワーク経由で接続できない設定なので注意。

  # Use default MacPorts settings
  #!include /opt/local/etc/mysql8/macports-default.cnf
  
  [client]
  default-character-set=utf8mb4
  [mysqld]
  basedir="/opt/local"
  character-set-server=utf8mb4
  max_allowed_packet = 32M
  [mysqldump]
  default-character-set=utf8mb4
  [mysql]
  default-character-set=utf8mb4
  

トラブルシューティング†[edit]

rubyの"mysql2"がインストールできない†[edit]

• 以下のようなエラーが発生。

  ld: library not found for -lzstd

• /opt/local/libの下にあるlibzstdを探してくれないらしい(ファイル自体はある)。
• 以下を実行したあとbundle installする。

  bundle config --local build.mysql2 "--with-ldflags=-L/opt/local/lib"
