我剛剛使用MariaDB在Debian 9.1上遇到了這個問題,但這在Oracle MysqL中應該是相同的.我可以從命令行輕松登錄,但PHP無法訪問數據庫.

我花了幾分鐘才弄明白,但我記得當時我曾經在舊服務器上使用Arch Linux(順便說一句愚蠢的想法),需要命令MysqL_secure_installation才能讓它接受連接.

嘗試一下,這對我有用.

NOTE: RUNNING ALL PARTS OF THIS SCRIPT IS RECOMMENDED FOR ALL MariaDB

SERVERS IN PRODUCTION USE! PLEASE READ EACH STEP CAREFULLY!

In order to log into MariaDB to secure it,we'll need the current

password for the root user. If you've just installed MariaDB,and

you haven't set the root password yet,the password will be blank,so you should just press enter here.

Enter current password for root (enter for none):

OK,successfully used password,moving on...

Setting the root password ensures that nobody can log into the MariaDB

root user without the proper authorisation.

Set root password? [Y/n] n

... skipping.

By default,a MariaDB installation has an anonymous user,allowing anyone

to log into MariaDB without having to have a user account created for

them. This is intended only for testing,and to make the installation

go a bit smoother. You should remove them before moving into a

production environment.

Remove anonymous users? [Y/n] y

... Success!

Normally,root should only be allowed to connect from 'localhost'. This

ensures that someone cannot guess at the root password from the network.

Disallow root login remotely? [Y/n] y

... Success!

By default,MariaDB comes with a database named 'test' that anyone can

access. This is also intended only for testing,and should be removed

before moving into a production environment.

Remove test database and access to it? [Y/n] y

- Dropping test database...

... Success!

- Removing privileges on test database...

... Success!

Reloading the privilege tables will ensure that all changes made so far

will take effect immediately.

Reload privilege tables now? [Y/n] y

... Success!

Cleaning up...

All done! If you've completed all of the above steps,your MariaDB

installation should now be secure.

Thanks for using MariaDB!
