Tips

クライアントからTCPプロトコルで接続できない?

[root@localhost /]# mysql --protocol=tcp -u root -p
Enter password:
ERROR 1045 (28000): Access denied for user 'root'@'localhost.localdomain' (using password: YES)

あ〜、、ホスト指定も必要だった。

[root@localhost /]# mysql --host=localhost -u root -p
Enter password:
Welcome to the MySQL monitor.  Commands end with ; or \g.
Your MySQL connection id is 15 to server version: 4.1.12

Type 'help;' or '\h' for help. Type '\c' to clear the buffer.

mysql> exit
Bye

でも外部からは接続できない・・・

接続元のホスト名、MySQLのユーザ名 でのアクセス制御で接続拒否されているっぽい。

↓ホスト名を任意でユーザ作成

mysql> grant all on *.* to root@'%' identified by '*********';
Query OK, 0 rows affected (0.05 sec)

mysql> use mysql
Reading table information for completion of table and column names
You can turn off this feature to get a quicker startup with -A

mysql> show tables;

  -?, --help          Display this help and exit.
  -I, --help          Synonym for -?
  --auto-rehash       Enable automatic rehashing. One doesn't need to use
                      'rehash' to get table and field completion, but startup
                      and reconnecting may take a longer time. Disable with
                      --disable-auto-rehash.
  -A, --no-auto-rehash
                      No automatic rehashing. One has to use 'rehash' to get
                      table and field completion. This gives a quicker start of
                      mysql and disables rehashing on reconnect. WARNING:

                      starts with this option ENABLED by default! Disable with
                      '-G'. Long format commands still work from the first
