    这是一个创建于 1928 天前的主题,其中的信息可能已经有所发展或是发生改变。

    前言

    自从 macOS 升级至 Mojave 后小问题不断,现在使用 Homebrew 安装 MySQL 默认也是 8.0 版本,和 Python 类似我们依赖的组件可能还不支持高版本,新版本的某些更新和调整导致比如 Sequel Pro 和 mysqldb 不可用。当然我们也可以使用官方的 MySQLWorkbench,之前介绍了如何在 macOS 下安装多版本 Python,现在继续分享 macOS 如何降级 MySQL。

    macOS Mojave 降级安装 MySQL 5.7

    更新历史

    2018 年 12 月 17 日 - 初稿

    Install MySQL 5.7 on macOS Mojave - https://medium.com/@at0dd/install-mysql-5-7-on-mac-os-mojave-cd07ec936034


    正常安装

    默认新版本是 MySQL 8.0

    brew update
    brew install mysql
    
    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
    
    

    卸载现有版本

    无论是官方 dmg 还是 brew 都记得先备份重要数据后再清理

    # 正常关闭并删除 MySQL
    mysql.server stop
    brew services stop mysql
    brew remove mysql
    
    # 无法正常删除 MySQL
    ps -ax | grep mysql
    stop and kill any MySQL processes
    brew remove mysql
    brew cleanup
    sudo rm /usr/local/mysql
    sudo rm -rf /usr/local/var/mysql
    sudo rm -rf /usr/local/mysql*
    
    

    安装 MySQL 指定版本

    # 安装 MySQL 5.7
    brew install [email protected]
    brew link --force [email protected]
    
    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
    
    [email protected] 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 [email protected] first in your PATH run:
      echo 'export PATH="/usr/local/opt/[email protected]/bin:$PATH"' >> ~/.zshrc
    
    For compilers to find [email protected] you may need to set:
      export LDFLAGS="-L/usr/local/opt/[email protected]/lib"
      export CPPFLAGS="-I/usr/local/opt/[email protected]/include"
    
    For pkg-config to find [email protected] you may need to set:
      export PKG_CONFIG_PATH="/usr/local/opt/[email protected]/lib/pkgconfig"
    
    
    To have launchd start [email protected] now and restart at login:
      brew services start [email protected]
    Or, if you don't want/need a background service you can just run:
      /usr/local/opt/[email protected]/bin/mysql.server start
    
    # 开机自启动
    brew services restart [email protected]
    # 设置环境变量
    echo 'export PATH="/usr/local/opt/[email protected]/bin:$PATH"' >> ~/.zshrc
    # 手动启动和关闭
    /usr/local/opt/[email protected]/bin/mysql.server start
    /usr/local/opt/[email protected]/bin/mysql.server stop
    
    

    安装 mysqldb

    Python 中最连接 Mysql 常用的驱动是:

    • mysql-python:mysql 的 C 语言的驱动
    • mysql-connector:msql 官方的驱动
    • pymysql:python 语言的驱动
    # 使用 MySQLdb,但是提示 importerror no module named mysqldb
    brew install mysql-connector-c
    pip install mysql-python
    
    # 可能会出现以下错误,按照提示做即可
    Error: Cannot install mysql because conflicting formulae are installed.
      mysql-connector-c: because both install MySQL client libraries
    
    Please `brew unlink mysql-connector-c` before continuing.
    
    Unlinking removes a formula's symlinks from /usr/local. You can
    link the formula again after the install finishes. You can --force this
    install, but the build may fail or cause obscure side-effects in the
    resulting software.

    macOS 的 docker 安装 mysql 5.7 也有 BUG,读写的时候会卡死好长时间。

    @wizardoz #3 确实有问题 插大量的数据后 Sequel Pro 就连不上了,重新生成 mysql 容器也不行,只能重启电脑才能连

    docker run --name mysql -p 3306:3306 -e MYSQL_ROOT_PASSWORD=你的密码 -d mysql:5.7
    一行解决

    我们的项目开发调试的时候就用 docker 跑 MySQL,没见着卡啊
