+---------------------------------+----------------------------------------+
/etc/my.cnf 파일에 wait_timeout을 1800000 값을 주고 다시 뛰우니. 다음과 같이 값을 얻어올 수 있었다.
mysql> select @@global.wait_timeout
-> ;
+-----------------------+
| @@global.wait_timeout |
+-----------------------+
| 1800000 |
+-----------------------+
1 row in set (0.00 sec)
mysql> select @@session.wait_timeout
-> ;
+------------------------+
| @@session.wait_timeout |
+------------------------+
| 28800 |
+------------------------+
1 row in set (0.00 sec)
