Salut
Am o problema mare si poate reusesc s-o rezolv cu ajutorul vostru:
am un server web si un site realizat cu ajutorul unui cms. Acest cms foloseste mysql ca si server de baze de date....
problema mea este ca nu ma mai pot conecta la server, zice ceva de genul: ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/var/lib/mysql/mysql.sock' (2).
Exista vre-o metoda de a rezolva problema fara reinstalarea serverului mysql?
Multumesc anticipat

ls -al /var/lib/mysql/mysql.sock ce zice? mysql e pornit?
Sper ca ai creat o baza de date si un user cu privilegii de scriere in ea ;D
ls: /var/lib/mysql/mysql.sock: No such file or directory
:(
Serverul a functionat pina ieri, cind, din graba si viteza am sters (mai mult decit probabil) mysql.sock
Pot recupara cumva acel fisier?
???

Am facut un test:
- am sters /var/lib/mysql/mysql.sock
- am repornint /etc/rc.d/init.d/mysqld
- socketul a fost creat inapoi
Vezi in /etc/my.cnf sa i pusa liniile de socket. La mine un "cat /etc/my.cnf | grep sock" returneaza asta:
[root@localhost mysql]# cat /etc/my.cnf | grep sock
socket = /var/lib/mysql/mysql.sock
socket = /var/lib/mysql/mysql.sock
# All interaction with mysqld must be made via Unix sockets or named pipes.
socket=/var/lib/mysql/mysqlmanager.sock
Sper sa-ti iasa, bafta.

fisierul ala se creeaza de fiecare data cand pornesti mysql
ps aux|grep mysql ce zice? mysql ruleaza?
La comanda:
[marius@marius cdrom]$ mysql -umarius -p
Enter password:

acelasi text il primesc si eu la comanda:
cat /etc/my.cnf | grep sock
[marius@marius cdrom]$ cat /etc/my.cnf | grep sock
socket = /var/lib/mysql/mysql.sock
socket = /var/lib/mysql/mysql.sock
# All interaction with mysqld must be made via Unix sockets or named pipes.
socket=/var/lib/mysql/mysqlmanager.sock
[marius@marius cdrom]$

aha, foarte ciudat, deci mysql merge, in my.cnf e definit socketul, dar el nu exista.
ia vezi, exista /tmp/mysql.sock?
Da Maxx, exact aeleasi linii ca si la tine... :(

tail -f /var/log/mysqld/mysqlmanager.log zice ceva?
nu, nu exista /tmp/mysql.sock

Probabil ca am sters ceva ce nu trebuia... (din lipsa de spatiu)

adauga in my.cnf: skip-innodb (banuiesc ca folosesti engine-ul MyISAM)
Maxx, ai o bere maaaare de la mine
Functioneaza, urraaa
Totusi, ca si "incepator", ce s-a intimplat?
Mersi mult de tot

probabil ai sters din fisierele alea .bin (care pot creste destul de mari) si atunci nu a mai mers innodb-ul (de care oricum nu prea ai nevoie).
Maaaaaaxx, asta nu este o rezolvare, ci o carpeala. Mie candva mi s-a rezolvat "mai adevarat": http://beranger.org/index.php?page=3k&article=661
Mai exact:
su mysql -c /usr/bin/mysql_install_dbomu stersese niste fisiere .bin legate de functionarea motorului innodb. in rest db-urile erau ok. mysql_install_db nu reinitializeaza tabelele user si db din baza mysql? asta ar fi fost neplacut.
