參數 | 可選值 | 含義 |
---|---|---|
sync_binlog | 0 | binlog刷盤持久化由操做系統完成,性能好,存在丟失binlog的風險 |
sync_binlog | 1 | 事務提交後刷盤持久化,最安全 |
sync_binlog | N | 在每N個事務提交後進行刷盤持久化 |
innodb_flush_log_at_trx_commit | 0 | 每秒鐘寫redo log 並刷盤持久化 |
innodb_flush_log_at_trx_commit | 1 | 事務提交後寫redo log 並刷盤持久化,最安全 |
innodb_flush_log_at_trx_commit | 2 | 事務提交後寫redo log , 每秒刷盤持久化 |

注意 sysbench 須要設置--db-ps-mode=disable 禁用預編譯語句,否則併發測試線程多時會報下面的錯誤 FATAL: mysql_stmt_prepare() failed FATAL: MySQL error: 1461 "Can't create more than max_prepared_stmt_count statements (current value: 16382)" FATAL: mysql_stmt_prepare() failed FATAL: MySQL error: 1461 "Can't create more than max_prepared_stmt_count statements (current value: 16382)" FATAL: thread_init' function failed: /usr/local/share/sysbench/oltp_common.lua:288: SQL API error FATAL: mysql_stmt_prepare() failed FATAL: MySQL error: 1461 "Can't create more than max_prepared_stmt_count statements (current value: 16382)" FATAL:
