[help] Linux e mysql strano errore

[Mitchell]

ciao a tutti raga ho installato su una debian mysql e phpmyadmin da apt e fin qui tutto bene quando tento di fare il test mysql mi esce con questo messaggio:
mysqltest: Failed in mysql_real_connect(): Can't connect to local MySQL server through socket '/var/run/mysqld/mysqld.sock' (2)
e andato su phpmyadmin mi dice:
#2002 - Can't connect to local MySQL server through socket '/var/lib/mysql/mysql.sock' (2)
qualcunoi ne sa qualcosa per come risolverelo ?

[ingpeo]

mysqld è installato e funzionante?
Riesci ad accederci con phpmyadmin?
Se si controlla di avere i privilegi di utente per collegarti.

[RaouL_BennetH]

a me sembra che appunto il demone mysqld non stia girando. Prova a dare semplicemente mysqld e poi riprova a connetterti.

[Mitchell]

allora raga mysqld lo messo da apt
però adesso che do
mysqld mi da questa cosa

To see what values a running MySQL server is using, type
'mysqladmin variables' instead of 'mysqld --help'.
The default values (after parsing the command line arguments) are:

tmpdir: /tmp/
language: /usr/share/mysql/english/
pid file: /var/run/mysqld/mysqld.pid
TCP port: 3306
Unix socket: /var/run/mysqld/mysqld.sock

system locking is not in use

scusate per il post kilometrico

[ingpeo]

e se provi a a fare: /etc/init.d/mysqld start
che succede?

[Mitchell]

succede questo:
~# /etc/init.d/mysqld start
bash: /etc/init.d/mysqld: No such file or directory

vabbe non e messo nel init.d ma però manualmente dovrebbe partire nò ?
