Tha iad ag ràdh gur e am facal-faire as fheàrr am fear nach fheum thu cuimhneachadh. A thaobh MySQL tha seo comasach le taing don plugan
Chan eil an dà plugan seo ùr idir; chaidh tòrr a ràdh mun deidhinn san aon bhlog seo, mar eisimpleir san artaigil mu dheidhinn
Mar a thuirt mi, chan e naidheachd a tha seo, agus nuair a bhios tu a ’stàladh MySQL a’ cleachdadh na pasganan .deb le taic bhon sgioba Debian, thèid cleachdaiche freumh a chruthachadh airson dearbhadh socaid. Tha seo fìor airson an dà chuid MySQL agus MariaDB.

Le pasganan Debian airson MySQL, tha an neach-cleachdaidh freumha air a dhearbhadh mar a leanas:
root@app:~# whoami
root=
root@app:~# mysql

1 row in set (0.01 sec)
Tha an aon rud fìor leis a’ phacaid .deb airson MariaDB:
10.0.38-MariaDB-0ubuntu0.16.04.1 Ubuntu 16.04
MariaDB [(none)]> show grants;
+------------------------------------------------------------------------------------------------+
| Grants for root@localhost |
+------------------------------------------------------------------------------------------------+

| GRANT PROXY ON ''@'%' TO 'root'@'localhost' WITH GRANT OPTION |
+------------------------------------------------------------------------------------------------+
2 rows in set (0.00 sec)
Bidh na pasganan .deb bho stòras oifigeil Percona cuideachd a 'rèiteachadh dearbhadh cleachdaiche bunaiteach fo auth-socket agus airson Percona Server. Bheir sinn eisimpleir le
root@app:~# whoami
root
root@app:~# mysql

Mar sin dè an draoidheachd a th’ ann? Bidh am plugan a’ dèanamh cinnteach gu bheil an cleachdaiche Linux a’ maidseadh an neach-cleachdaidh MySQL a’ cleachdadh an roghainn socaid SO_PEERCRED gus fiosrachadh a chruinneachadh mun neach-cleachdaidh a tha a’ ruith a’ phrògram teachdaiche. Mar sin, chan urrainnear am plugan a chleachdadh ach air siostaman a bheir taic don roghainn SO_PEERCRED, leithid Linux. Leigidh an roghainn socaid SO_PEERCRED leat faighinn a-mach uid a’ phròiseis co-cheangailte ris an t-socaid. Agus an uairsin tha e mu thràth a’ faighinn an t-ainm-cleachdaidh co-cheangailte ris an uid seo.
Seo eisimpleir leis a’ chleachdaiche “vagrant”:
vagrant@mysql1:~$ whoami
vagrant
vagrant@mysql1:~$ mysql
ERROR 1698 (28000): Access denied for user 'vagrant'@'localhost'
Leis nach eil neach-cleachdaidh “vagrant” ann am MySQL, tha ruigsinneachd air a dhiùltadh dhuinn. Cruthaichidh sinn a leithid de chleachdaiche agus feuch ris a-rithist:
MariaDB [(none)]> GRANT ALL PRIVILEGES ON *.* TO 'vagrant'@'localhost' IDENTIFIED VIA unix_socket;
Query OK, 0 rows affected (0.00 sec)
vagrant@mysql1:~$ mysql

Thachair!
Uill, dè mu dheidhinn cuairteachadh neo-Debian far nach eil seo air a thoirt seachad gu bunaiteach? Feuch sinn Percona Server airson MySQL 8 air a chuir a-steach air CentOS 7:
mysql> show variables like '%version%comment';
+-----------------+---------------------------------------------------+
| Variable_name | Value |
+-----------------+---------------------------------------------------+
| version_comment | Percona Server (GPL), Release 7, Revision 613e312 |
+-----------------+---------------------------------------------------+
1 row in set (0.01 sec)
mysql> CREATE USER 'percona'@'localhost' IDENTIFIED WITH auth_socket;
ERROR 1524 (HY000): Plugin 'auth_socket' is not loaded
Bummer. Dè bha a dhìth? Plugin gun luchdachadh:
mysql> pager grep socket
PAGER set to 'grep socket'
mysql> show plugins;
47 rows in set (0.00 sec)
Nach cuir sinn plugan ris a’ phròiseas:
mysql> nopager
PAGER set to stdout
mysql> INSTALL PLUGIN auth_socket SONAME 'auth_socket.so';
Query OK, 0 rows affected (0.00 sec)
mysql> pager grep socket; show plugins;
PAGER set to 'grep socket'
| auth_socket | ACTIVE | AUTHENTICATION | auth_socket.so | GPL |
48 rows in set (0.00 sec)
A-nis tha a h-uile dad a tha a dhìth oirnn. Feuch sinn a-rithist:
mysql> CREATE USER 'percona'@'localhost' IDENTIFIED WITH auth_socket;
Query OK, 0 rows affected (0.01 sec)
mysql> GRANT ALL PRIVILEGES ON *.* TO 'percona'@'localhost';
Query OK, 0 rows affected (0.01 sec)
Faodaidh tu a-nis logadh a-steach leis an ainm-cleachdaidh “percona”.
[percona@ip-192-168-1-111 ~]$ whoami
percona
[percona@ip-192-168-1-111 ~]$ mysql -upercona

+---------+-----------+-------------+-----------------------+
1 row in set (0.00 sec)
Agus dh'obraich e a-rithist!
Ceist: am bi e comasach logadh a-steach don t-siostam fon aon logadh a-steach percona, ach mar neach-cleachdaidh eile?
[percona@ip-192-168-1-111 ~]$ logout
[root@ip-192-168-1-111 ~]# mysql -upercona
ERROR 1698 (28000): Access denied for user 'percona'@'localhost'
Chan e, chan obraich e.
co-dhùnadh
Tha MySQL gu math sùbailte ann an grunn thaobhan, agus is e aon dhiubh an dòigh dearbhaidh. Mar a chì thu bhon phost seo, gheibhear ruigsinneachd às aonais faclan-faire, stèidhichte air luchd-cleachdaidh OS. Faodaidh seo a bhith feumail ann an cuid de shuidheachaidhean, agus tha aon dhiubh nuair a bhios tu a’ gluasad bho RDS/Aurora gu MySQL gu cunbhalach a’ cleachdadh
