Question

我正在尝试重新安装Mac OSX LAMP并运行命令

#include <stdio.h>
#include <stdlib.h>

int yylex (void);
void yyerror (char const *);

我输入了root密码，当我遇到此错误时，我必须输入一个新密码，有没有人有这方面的经验？

mysql_secure_installation

Answer 1

请执行以下命令重试完全删除mysql：

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

然后重新启动计算机以确保所有进程都已被终止。

然后执行这些命令来安装MySQL：

brew update
brew install mysql
unset TMPDIR
mysql_install_db --verbose --user='<your-username>' --basedir="$(brew --prefix mysql)" --datadir=/usr/local/var/mysql --tmpdir=/tmp
mysql.server start

这应该可以解决问题。

我认为安装中存在损坏，并决定删除并使用brew进行安装，现在一切都很好！请按照以下步骤操作

然后通过Brew安装

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*

＆＃39; ./ MySQL的/ user.MYD就＆＃39;未找到（错误代码：13 - 权限被拒绝）
