E ai ki a ratou ko te kupuhipa pai rawa atu ko te mea kaore koe e mahara. I roto i te take o MySQL ka taea tenei whakawhetai ki te mono me tana putanga mo MariaDB - .
Ko enei mono e rua ehara i te mea hou; he maha nga korero mo ratou i roto i tenei blog kotahi, hei tauira i roto i te tuhinga mo . Heoi, i a au e titiro ana ki nga mea hou i roto i te MariaDB 10.4, i kitea e au ko te unix_socket kua whakauruhia inaianei ma te taunoa me tetahi o nga tikanga motuhēhēnga (“tetahi o”, no te mea kei roto i te MariaDB 10.4 neke atu i te kotahi mono kei te waatea ki te kaiwhakamahi kotahi mo te whakamotuhēhēnga, e kua whakamaramatia i roto i te tuhinga ).
Ka rite ki taku korero, ehara tenei i te korero, a, i te wa e whakauru ana i a MySQL ma te whakamahi i nga kohinga .deb e tautokohia ana e te roopu Debian, ka hangaia he kaiwhakamahi pakiaka mo te motuhēhēnga turanga. He pono tenei mo MySQL me MariaDB.

1 row in set (0.00 sec)Na he aha te makutu? Ka tirohia e te mono kei te taurite te kaiwhakamahi Linux ki te kaiwhakamahi MySQL ma te whakamahi i te whiringa turanga SO_PEERCRED hei kohikohi korero mo te kaiwhakamahi e whakahaere ana i te kaupapa kiritaki. No reira, ka taea anake te whakamahi i te mono ki nga punaha e tautoko ana i te whiringa SO_PEERCRED, penei i a Linux. Ko te kōwhiringa turanga SO_PEERCRED ka taea e koe te kimi i te uid o te tukanga e pa ana ki te turanga. Na ka whiwhi ia i te ingoa kaiwhakamahi e hono ana ki tenei uid.
Anei tetahi tauira me te kaiwhakamahi "vagrant":
vagrant@mysql1:~$ whoami
vagrant
vagrant@mysql1:~$ mysql
ERROR 1698 (28000): Access denied for user 'vagrant'@'localhost'I te mea karekau he "kaiwhakamahi" i MySQL, karekau matou e uru. Me hanga he kaiwhakamahi penei ka ngana ano:
MariaDB [(none)]> GRANT ALL PRIVILEGES ON *.* TO 'vagrant'@'localhost' IDENTIFIED VIA unix_socket;
Query OK, 0 rows affected (0.00 sec)

Ae, me pehea te tohatoha kore-Debian kaore i te whakaratohia ma te taunoa? Me whakamatau te Percona Server mo MySQL 8 i whakauruhia ki CentOS 7:

mysql> pager grep socket
PAGER set to 'grep socket'
mysql> show plugins;
47 rows in set (0.00 sec)Me taapiri he mono ki te tukanga:

mutunga
He tino ngawari a MySQL i roto i nga waahanga maha, ko tetahi ko te tikanga motuhēhēnga. Ka taea e koe te kite mai i tenei pou, ka taea te uru me te kore kupuhipa, i runga i nga kaiwhakamahi OS. Ka whai hua tenei ki etahi ahuatanga, a ko tetahi o enei ko te heke mai i te RDS/Aurora ki te whakamahi i a MySQL. kia whai waahi tonu, engari kaore he kupuhipa.
