MySQL 物理组成

MySQL 物理组成的配置

log-bin = /mysql/log/mysql-bin # binlog的存储路径
innodb_log_file_size = 1000M # 每个redo log文件的大小
innodb_log_files_in_group = 3 # redo log文件数量
log-error = /mysql/log/mysql-error.log # 错误日志的存储路径
slow_query_log = 1 #开启慢查询
long_query_time = 1 #设置慢查询阈值为1s
slow_query_log_file = /mysql/log/mysql-slow.log #设置慢查询日志存储路径
general_log = OFF #默认是关闭的
general_log_file = /mysql/data/mysql-general.log #设置查询日志存储路径
innodb_file_per_table = 1  #1 为开启独享表空间
