MacOS 修改mysql默认的charset和collation

查看当前MySQL可用 CHARSET

SHOW CHARACTER SET;

查看可用 COLLATION

SHOW COLLATION;

修改启动参数：vi /usr/local/Cellar/mysql/MYSQL版本/homebrew.mxcl.mysql.plist

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">
<dict>
  <key>KeepAlive</key>
  <true/>
  <key>Label</key>
  <string>homebrew.mxcl.mysql</string>
  <key>ProgramArguments</key>
  <array>
    <string>/usr/local/opt/mysql/bin/mysqld_safe</string>
    <string>--character-set-server=utf8mb4</string>
    <string>--collation-server=utf8mb4_general_ci</string>
    <string>--bind-address=0.0.0.0</string>
    <string>--datadir=/usr/local/var/mysql</string>
  </array>
  <key>RunAtLoad</key>
  <true/>
  <key>WorkingDirectory</key>
  <string>/usr/local/var/mysql</string>
</dict>
</plist>

另一个方式是修改 配置文件 sudo vi /private/etc/my.cnf

[mysqld]
...

character-set-server=utf8mb4
collation-server=utf8mb4_general_ci

...
