mysql数据库中my.ini的优化,2G内存,针对站多,抗压型的设置.大家可以借鉴下。
物理内存越大,设置就越大.默认为2402,调到512-1024最佳
innodb_additional_mem_pool_size=4M 默认为2M
innodb_flush_log_at_trx_commit=1
(设置为0就是等到innodb_log_buffer_size列队满后再统一储存,默认为1)
innodb_log_buffer_size=2M 默认为1M
innodb_thread_concurrency=8 你的服务器CPU有几个就设置为几,建议用默认一般为8
key_buffer_size=256M 默认为218 调到128最佳
tmp_table_size=64M 默认为16M 调到64-256最挂
read_buffer_size=4M 默认为64K
read_rnd_buffer_size=16M 默认为256K
sort_buffer_size=32M 默认为256K
max_connections=1024 默认为1210
thread_cache_size=120 默认为60
query_cache_size=64M
