brew安装不起作用。这是日志。

Try 'mysqld --help' if you have problems with paths.  Using
--general-log gives you a log in /usr/local/var/mysql that may be helpful.

Warning: The post-install step did not complete successfully
You can try again using `brew postinstall mariadb`
==> Caveats
A "/etc/my.cnf" from another install may interfere with a Homebrew-built
server starting up correctly.

MySQL is configured to only allow connections from localhost by default

To start mariadb:
  brew services start mariadb
Or, if you don't want/need a background service you can just run:
  mysql.server start

我已尝试执行mysql_install_db

我试过在没有brew的情况下执行mysql_install_db。这是日志。brew只显示最后15行，所以我没办法。

Couldn't set an owner to '/usr/local/Cellar/mariadb/10.4.13/lib/plugin/auth_pam_tool_dir/auth_pam_tool'.
It must be root, the PAM authentication plugin doesn't work otherwise..

Installation of system tables failed!  Examine the logs in

The problem could be conflicting information in an external
my.cnf files. You can ignore these by doing:

    shell> /usr/local/Cellar/mariadb/10.4.13/bin/mysql_install_db --defaults-file=~/.my.cnf

You can also try to start the mysqld daemon with:

    shell> /usr/local/Cellar/mariadb/10.4.13/bin/mysqld --skip-grant-tables --general-log &

and use the command line tool /usr/local/Cellar/mariadb/10.4.13/bin/mysql
to connect to the mysql database and look at the grant tables:

    shell> /usr/local/Cellar/mariadb/10.4.13/bin/mysql -u root mysql
    mysql> show tables;

Try 'mysqld --help' if you have problems with paths.  Using
--general-log gives you a log in /usr/local/var/mysql that may be helpful.

我注意到系统无法将chown用于auth_pam_tool，因为不允许操作。

验证pam工具权限

这是我的权限目录。

% ls -l /usr/local/Cellar/mariadb/10.4.13/lib/plugin/auth_pam_tool_dir/auth_pam_tool
-r-xr-xr-x  1 shingo  staff  13608  5 10 04:28 /usr/local/Cellar/mariadb/10.4.13/lib/plugin/auth_pam_tool_dir/auth_pam_tool

如何修复不允许的操作？
还是有其他原因导致无法安装？
