最近服务器日志上老出现错误提示，改了几次配置还是有，请各位有经验的朋友指点一下。Changed limits: max_open_files: 2048 max_connections: 1024 table_cache: 507For more information, see Help and Support Center at http://www.mysql.com.
内存是4G
引擎是INNODB
操作中select居多，update略次
网站与数据库同一机器，流量约2万IP左右，并发没统计过，请指点，下面的配置要更改那些？当前配置：# The default character set that will be used when a new schema or table is
# created and no character set is defined
default-character-set=gbk# The default storage engine that will be used when create new tables when
default-storage-engine=INNODB# Set the SQL mode to strict

max_connections=1024query_cache_size=128Mtable_cache=500 估计你这是由于max_connections 、max_open_files、table_cache 相关值不匹配造成的。
max_allowed_packet = 1M
table_open_cache = 512
sort_buffer_size = 2M
read_buffer_size = 2M
read_rnd_buffer_size = 8M
myisam_sort_buffer_size = 64M
thread_cache_size = 8
query_cache_size = 32M
thread_concurrency = 85.1.36版本和你不一样，大同小异
