Je ne peux pas telnet MySQL sur mon hôte local. MySQL est opérationnel et fonctionne correctement avec le serveur Apache-SSL / PHP / MySQL, mais je ne peux pas me connecter par telnet:
telnet 127.0.0.1 3306
Trying 127.0.0.1...
telnet: Unable to connect to remote host: Connection timed out
La même chose pour localhost
telnet localhost 3306
Trying 127.0.0.1...
Trying ::1...
telnet: Unable to connect to remote host: Connection timed out
Netstat confirme que MySQL est exécuté sur le port 3306:
netstat -alpent | grep 3306
tcp 0 0 127.0.0.1:3306 0.0.0.0:* LISTEN 105 522804419 17231/mysqld

Je peux me connecter avec -h localhost:
mysql -h localhost -u root -p
Enter password:

Mais je ne peux pas me connecter avec -h 127.0.0.1:
mysql -h 127.0.0.1 -u root -p
Enter password:
ERROR 2003 (HY000): Can't connect to MySQL server on '127.0.0.1' (110)
Et pourtant, j'ai mis bind-address 127.0.01, vi /etc/mysql/my.cnf: ...
# Instead of skip-networking the default is now to listen only on
# localhost which is more compatible and is not less secure.
#bind-address = localhost
bind-address = 127.0.0.1
Et j'ai redémarré MySQL:
/etc/init.d/mysql restart
Rather than invoking init scripts through /etc/init.d, use the service(8)
utility, e.g. service mysql restart
Since the script you are attempting to invoke has been converted to an
Upstart job, you may also use the stop(8) and then start(8) utilities,
e.g. stop mysql ; start mysql. The restart(8) utility is also available.
mysql stop/waiting
mysql start/running, process 17464
Les règles IPTables sont vides:

Donc, je ne sais pas quoi vérifier et Postfix ne peut pas se connecter à MySQL. Est-ce que quelqu'un sait ce que je devrais vérifier?
En fait, je ne peux pas me connecter à aucun service du serveur:
telnet 127.0.0.1 80
Trying 127.0.0.1...
telnet: Unable to connect to remote host: Connection timed out
telnet 127.0.0.1 443
