mysql - Mac 无法启动 MYSQL 服务器

Question

我目前正在尝试在 Mac 上运行 mysql 服务器，但是从首选项 Pane 中启动 MySQL 服务器不起作用，从终端启动它也不起作用。我找到了很多修复方法，但没有一个有效。这是我第一次使用 MySQL，我的编程经验很少(只有一点 Java)，这是我很长一段时间以来第一篇 StackOverflow 帖子(如果我做错了，请帮助我学习!)。

我安装了这个版本(没有使用brew):mysql-5.7.21-1-macos10.13-x86_64 我的机器是64位

我尝试过的:

1. 使用此过程卸载并重新安装 MySQL:

To uninstall MySQL and completely remove it (including all databases) from your Mac do the following:

Open a terminal window Use mysqldump to backup your databases to text files! Stop the database server sudo rm /usr/local/mysql sudo rm -rf /usr/local/mysql* sudo rm -rf /Library/StartupItems/MySQLCOM sudo rm -rf /Library/PreferencePanes/My* edit /etc/hostconfig and remove the line MYSQLCOM=-YES- rm -rf ~/Library/PreferencePanes/My* sudo rm -rf /Library/Receipts/mysql* sudo rm -rf /Library/Receipts/MySQL* sudo rm -rf /private/var/db/receipts/mysql https://community.jaspersoft.com/wiki/uninstall-mysql-mac-os-x

当我打开安装 mysql 的文件夹时，我没有权限打开数据或钥匙串(keychain)文件夹。所以，我认为这是一个权限问题并尝试了这个:Cannot start Mysql on Mac 。当我尝试启动服务器时，出现以下错误:

sudo /usr/local/mysql/support-files/mysql.server start Starting MySQL .Logging to '/usr/local/mysql/data/XXXXs-MacBook-Air.local.err'. /usr/local/mysql/bin/mysqld_safe: line 198: 7892 Trace/BPT trap: 5
nohup /usr/local/mysql/bin/mysqld --basedir=/usr/local/mysql --datadir=/usr/local/mysql/data --plugin-dir=/usr/local/mysql/lib/plugin --user=mysql --log-error=XXXXs-MacBook-Air.local.err --pid-file=/usr/local/mysql/data/XXXXs-MacBook-Air.local.pid < /dev/null > /dev/null 2>&1 ERROR! The server quit without updating PID file (/usr/local/mysql/data/XXXXs-MacBook-Air.local.pid).

尝试检查管理版本并收到以下错误:

XXXXs-MacBook-Air:mysql XXXX$ bin/mysqladmin version mysqladmin: connect to server at 'localhost' failed error: 'Can't connect to local MySQL server through socket '/tmp/mysql.sock' (2)' Check that mysqld is running and that the socket: '/tmp/mysql.sock' exists!

尝试从命令行打开/temp/mysql.sock，但发现它不存在

尝试过这个:

XXXXs-MacBook-Air:mysql XXXX$ % mysqladmin variables -bash: fg: %: no such job XXXXs-MacBook-Air:mysql XXXX$ mysqladmin variables -bash: mysqladmin: command not found

尝试按照 this post 删除 my.cnf并重新启动服务器

sudo rm -rf /etc/my.cnf sudo /usr/local/mysql/support-files/mysql.server start

已尝试这些说明 MySql server startup error 'The server quit without updating PID file '

XXXXs-MacBook-Air:mysql XXXX$ ps -ef | grep mysql 501 9173

现在我又回到了这个错误:

ERROR! The server quit without updating PID file (/usr/local/mysql/data/XXXXs-MacBook-Air.local.pid).

请帮忙!

编辑:我用brew卸载并重新安装。使用这些说明:http://stefan.magnuson.co/articles/osx/reinstalling-mysql-on-osx-with-homebrew/现在可以了。
