Question

我面临着大多数人在启动MYSQL时遇到的相同问题。我在Stack Overflow和其他论坛上阅读了很多主题，但没有任何帮助。

我在寻找一些帮助，请。

以下是我尝试的步骤-

Shrek-MacBook-Pro:~ Shrek_User$ brew services start mariadb
==> Successfully started `mariadb` (label: homebrew.mxcl.mariadb)

Shrek-MacBook-Pro:~ Shrek_User$ brew services list
Name       Status  User       Plist
grafana    stopped            
httpd      stopped            
mariadb    started Shrek_User /Users/Shrek_User/Library/LaunchAgents/homebrew.mxcl.mariadb.plist
php@5.6    stopped            
prometheus stopped 



Shrek-MacBook-Pro:~ Shrek_User$ which mysql
/usr/local/bin/mysql

Shrek-MacBook-Pro:~ Shrek_User$ mysql -u root
ERROR 1045 (28000): Access denied for user 'root'@'localhost' (using password: NO)
Shrek-MacBook-Pro:~ Shrek_User$



Shrek-MacBook-Pro:~ Shrek_User$ mysql -u root -p
Enter password: 
ERROR 1045 (28000): Access denied for user 'root'@'localhost' (using password: NO)


Shrek-MacBook-Pro:~ Shrek_User$ mysql -u root -p
Enter password: 
ERROR 1045 (28000): Access denied for user 'root'@'localhost' (using password: YES)
Shrek-MacBook-Pro:~ Shrek_User$

尝试以相同模式停止和启动。

Shrek-MacBook-Pro:~ Shrek_User$ brew services stop mariadb
Stopping `mariadb`... (might take a while)

==> Successfully stopped `mariadb` (label: homebrew.mxcl.mariadb)
Shrek-MacBook-Pro:~ Shrek_User$

Shrek-MacBook-Pro:~ Shrek_User$ 
Shrek-MacBook-Pro:~ Shrek_User$ sudo mysqld_safe --skip-grant-tables --skip-networking
Password:
190201 22:24:49 mysqld_safe Logging to '/usr/local/var/Shrek-MacBook-Pro.local.err'.
190201 22:24:49 mysqld_safe Starting mysqld daemon with databases from /usr/local/var
Shrek-MacBook-Pro:~ Shrek_User$

但是，当在 '/usr/local/var/Shrek-MacBook-Pro.local.err' 日志文件看去，它打印：

Shrek-MacBook-Pro:~ Shrek_User$ cat /usr/local/var/Shrek-MacBook-Pro.local.err

Shrek-MacBook-Pro:~ Shrek_User$

当通过另一壳/终端窗口试图登录，看起来像服务器进程没有启动。

Shrek-MacBook-Pro:~ Shrek_User$ mysql -u root
ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/tmp/mysql.sock' (2)
Shrek-MacBook-Pro:~ Shrek_User$

如何解决此问题？任何帮助表示赞赏。

我尝试了以下方法，并且有效。

brew remove mariadb
brew cleanup
brew services list
sudo rm -rf /usr/local/var/mysql

brew install mariadb

mysql --version
   mysql  Ver 15.1 Distrib 10.3.12-MariaDB, for osx10.14 (x86_64) using readline 5.1

brew services start mariadb

我能够启动MariaDB服务器-

Shrek-MacBook-Pro:~ Shrek_User $ mysql -u root
Welcome to the MariaDB monitor.  Commands end with ; or \g.
Your MariaDB connection id is 10
Server version: 10.3.12-MariaDB Homebrew

Type 'help;' or '\h' for help. Type '\c' to clear the current input statement.
