Bathi igama eliyimfihlo elingcono kakhulu lelo akudingekile ukuba ulikhumbule. Endabeni ye-MySQL lokhu kungenzeka ngenxa ye-plugin kanye nenguqulo yayo ye-MariaDB - .
Womabili lawa ma-plugin awamusha nhlobo; kuningi osekushiwo ngawo kule bhulogi efanayo, isibonelo esihlokweni mayelana . Kodwa-ke, ngenkathi ngibheka ukuthi yini entsha ku-MariaDB 10.4, ngathola ukuthi i-unix_socket manje isifakwe ngokuzenzakalelayo futhi ingenye yezindlela zokuqinisekisa (βeyodwa yazoβ, ngoba ku-MariaDB 10.4 i-plugin engaphezu kweyodwa itholakala kumsebenzisi oyedwa ukuze iqinisekiswe, okuyinto kuchazwe embhalweni ).
Njengoba ngishilo, lokhu akuzona izindaba, futhi lapho ufaka i-MySQL usebenzisa amaphakheji we-.deb asekelwa ithimba le-Debian, umsebenzisi wempande udalelwa ukuqinisekiswa kwesokhethi. Lokhu kuyiqiniso kokubili i-MySQL ne-MariaDB.

1 row in set (0.00 sec)Uyini-ke umlingo? I-plugin ihlola ukuthi umsebenzisi we-Linux ufana nomsebenzisi we-MySQL esebenzisa inketho yesokhethi ye-SO_PEERCRED ukuqoqa ulwazi mayelana nomsebenzisi osebenzisa uhlelo lweklayenti. Ngakho, i-plugin ingasetshenziswa kuphela kumasistimu asekela inketho ye-SO_PEERCRED, njenge-Linux. Inketho yesokhethi ye-SO_PEERCRED ikuvumela ukuthi uthole i-uid yenqubo ehlotshaniswa nesokhethi. Futhi-ke usevele ethola igama lomsebenzisi elihlobene nale uid.
Nasi isibonelo ngomsebenzisi "vagrant":
vagrant@mysql1:~$ whoami
vagrant
vagrant@mysql1:~$ mysql
ERROR 1698 (28000): Access denied for user 'vagrant'@'localhost'Njengoba engekho umsebenzisi "ohambahambayo" ku-MySQL, sinqatshelwe ukufinyelela. Masidale umsebenzisi onjalo bese sizame futhi:
MariaDB [(none)]> GRANT ALL PRIVILEGES ON *.* TO 'vagrant'@'localhost' IDENTIFIED VIA unix_socket;
Query OK, 0 rows affected (0.00 sec)

Nokho, kuthiwani ngokusabalalisa okungeyona i-Debian lapho lokhu kunganikezwa ngokuzenzakalelayo? Ake sizame i-Percona Server ye-MySQL 8 efakwe ku-CentOS 7:

mysql> pager grep socket
PAGER set to 'grep socket'
mysql> show plugins;
47 rows in set (0.00 sec)Masingeze i-plugin kunqubo:
mysql> nopager

mysql> pager grep socket; show plugins;

mysql> GRANT ALL PRIVILEGES ON *.* TO 'percona'@'localhost';

isiphetho
I-MySQL iguquguquka kakhulu ezicini ezimbalwa, enye yazo indlela yokuqinisekisa. Njengoba ubona kulokhu okuthunyelwe, ukufinyelela kungatholwa ngaphandle kwamaphasiwedi, ngokusekelwe kubasebenzisi be-OS. Lokhu kungaba wusizo ezimeni ezithile, futhi esinye sazo kulapho ufuduka usuka ku-RDS/Aurora uye ku-MySQL evamile usebenzisa. ukuze uthole ukufinyelela, kodwa ngaphandle kwamaphasiwedi.
