Log all mysql queries

For the record, to log all mysql queries (as opposed to the slow query log, which only runs "slow" queries, even when you set the threshold to 0) on a running database (i.e. without a restart):

mysql> set global general_log=1;
Query OK, 0 rows affected (0.02 sec)

mysql> select @@global.general_log;
+----------------------+
| @@global.general_log |
+----------------------+
|                    1 |
+----------------------+
1 row in set (0.00 sec)

mysql> select @@global.general_log_file;
+--------------------------------+
| @@global.general_log_file      |
+--------------------------------+
| /usr/local/var/mysql/peach.log |
+--------------------------------+
1 row in set (0.00 sec)

then tail -f /usr/local/var/mysql/peach.log to get your stream of queries.
