060721 19:25:38  mysqld started
060721 19:25:38  Warning: Could not increase number of max_open_files to more than 200 (request: 8192)

我设置的
[mysqld]
port            = 8848
socket          = /opt/var/mysql.sock
skip-locking
back_log = 100
key_buffer_size = 384M
max_allowed_packet = 2M
table_cache = 512
sort_buffer_size = 2M
read_buffer_size = 2M
read_rnd_buffer_size = 8M
myisam_sort_buffer_size = 64M
thread_cache = 8
query_cache_size= 32M
max_connections=450
open_files_limit = 8192
skip-name-resolv



这个max_open_files 是从哪里设置的？
