Debian MariaDB内存调整策略:解决数据库运行速度痛点
使用者痛点:MariaDB运行缓慢、查询响应时间长、内存使用不合理导致频繁GC,程序负载过高?别担心,
1. 主要参数调优:精准分配每一字节
innodb_buffer_pool_size = 10G
innodb_buffer_pool_instances = 4
innodb_log_file_size = 256M
innodb_flush_log_at_trx_commit = 2
innodb_flush_method = O_DIRECT
key_buffer_size = 16M
query_cache_type = 0
max_connections = 200
thread_cache_size = 100
read_buffer_size = 128K
read_rnd_buffer_size = 256K
sort_buffer_size = 2M
join_buffer_size = 1M
binlog_cache_size = 64K
tmp_table_size = 128M
max_heap_table_size = 128M
关键说明:
-
innodb_buffer_pool_size设为总内存的70% - 推荐值。
