Error 2002

[Επισκέπτης]

Τρέχω Debian 3.1 και χωρίς να πειράξω τίποτα σχετικά με τη mysql, απλά την εγκατέστησα, προσπαθώ να τη σηκώσω και βγαίνει:

 

ERROR 2002: Can't connect to local MySQL server through socket '/var/run/mysqld/mysqld.sock' (111)

 

Την έβγαλα την ξαναέβαλα και πάλι τα ίδια.

Κανονικά αφου δεν πείραξα τίποτα, δεν έπρεπε by default να δουλεύει σωστά :lol: ?

Απλά δεν τρέχεις το mysql server, πας να τρέξεις τον mysql command line client ;-)

Δοκίμασε /etc/init.d/mysql start πρώτα.

[Επισκέπτης]

Δοκίμασα και παίρνω αποτέλεσμα:

 

server1:~# /etc/init.d/mysql start

Starting MySQL database server: mysqld...failed.

Please take a look at the syslog.

/usr/bin/mysqladmin: connect to server at 'localhost' failed

error: 'Can't connect to local MySQL server through socket '/var/run/mysqld/mysqld.sock' (2)'

Check that mysqld is running and that the socket: '/var/run/mysqld/mysqld.sock' exists!

Πώς μπορώ να λύσω αυτό το πρόβλημα???

[capthookb]

Πρέπει να δεις στο syslog τι μηνύματα λάθους σου εμφανίζει, ώστε να δεις τι φταίει και να το φτιάξεις. (Πρέπει να είναι το αρχείο /var/log/syslog ή κάτι τέτοιο τέλος πάντων)

Έκανες κάποιο upgrade στην mysql;

Από λίγο που έψαξα κάτι έχει πάει στραβά με την εγκατάσταση. Όπως είδες στο log δε βρίσκει το αρχείο host.MYI

Πολλοί αντιμετώπισαν το ίδιο μήνυμα λάθους μετά από upgrade σε 4.1 και 2-3 έλυσαν το πρόβλημα αφαιρώντας πλήρως τη mysql και κάνοντας νέα εγκατάσταση.

[capthookb]

Μπορείς να ψάξεις να δεις που υπάρχει το αρχείο host.MYI ;

Σε κονσόλα γράψε:

>$ find / -name "host.MYI"

[Επισκέπτης]

/var/lib/mysql/mysql/host.MYI

[apoikos]

Μάλλον δεν έχει δημιουργηθεί σωστά η αρχική βάση δεδομένων. Δοκίμασε ένα dpkg-reconfigure mysql.

[Επισκέπτης]

Δεν υπάρχει πακέτο mysql οπότε και δεν τρέχει η εντολή

[capthookb]

Μήπως είναι mysql-server το πακέτο; Δηλαδή

>dpkg-reconfigure mysql-server
