无法在mac上启动mysql服务器[email protected]

Question

我想在mac上设置[email protected]。我的本地有多个版本的mysql，我把它们都删除了，按照这个帖子的步骤安装了[email protected]。在通过Brew安装MySQL后，我得到了一个错误 - 服务器没有更新PID文件就退出了。:

brew remove mysql
brew cleanup
launchctl unload -w ~/Library/LaunchAgents/homebrew.mxcl.mysql.plist
rm ~/Library/LaunchAgents/homebrew.mxcl.mysql.plist
sudo rm -rf /usr/local/var/mysql

brew install [email protected]

ln -s /usr/local/Cellar/mysql\@5.6/5.6.47/bin/mysql /usr/local/bin/mysql

我没有 my.cnf 文件夹 /etc所以我用以下内容创建了这个。

 [mysqld]
 bind-address = 127.0.0.1

现在，当我做 mysql.server start遇到以下错误。

... ERROR! The server quit without updating PID file (/usr/local/var/mysql/my.pid).

我检查了日志文件，我看到以下错误。

2020-04-28 11:17:49 48498 [ERROR] Aborting

然后，我按照这个帖子。无法打开mysql.plugin表。请运行mysql_upgrade来创建它。并运行以下命令。

  /usr/local/Cellar/mysql\@5.6/5.6.47/bin/mysqld --initialize-insecure

但我还是看到同样的错误。

编辑：我找到了my.cnf文件，它位于usrlocaletc内。

我找到了my.cnf文件，它位于usrlocaletc里面。

我删除了mysqlx-bind-address，现在我得到了以下错误。

2020-04-28 14:16:13 97501 [ERROR] Fatal error: Can't open and lock privilege tables: Table 'mysql.user' doesn't exist
2020-04-28 14:16:35 98713 [ERROR] Can't open the mysql.plugin table. Please run mysql_upgrade to create it.

我已经解决了这个运行以下命令。

mysql_install_db --verbose --user=`whoami` --basedir=/usr/local/Cellar/mysql\@5.6/5.6.47 --datadir=/usr/local/var/mysql --tmpdir=/tmp

我从这里得到这个想法。https:/coderwall.compos6woquninstall-all-those-broken-versions-of-mysql-and-re-install-it-with-brew-on-mac-mavericks。

然后与 mysql.server start，mysql DB服务器起来了，没有任何错误。谢谢。
