如何进行MySQL数据库mysql-bin日志的管理与维护,相信很多没有经验的人对此束手无策,为此本文总结了问题出现的原因和解决方法,通过这篇文章希望你能解决这个问题。
在Mysql中,如果启用mysql-bin日志记录,则Mysql的变更修改都会被记录到日志文件中:
1 2 3 4 5 6 7 8 9 10 11 12 13 | mysql> show global variables like ‘%bin%’; +———————————+———————-+ | Variable_name | Value | +———————————+———————-+ | binlog_cache_size | 32768 | | innodb_locks_unsafe_for_binlog | OFF | | log_bin | ON | | log_bin_trust_function_creators | OFF | | max_binlog_cache_size | 18446744073709547520 | | max_binlog_size | 104857600 | | sync_binlog | 0 | +———————————+———————-+ 7 rows in set (0.00 sec) |
如果使用了配置文件,则可以修改 /etc/my.cnf 把里面的log-bin这一行注释掉,重启mysql服务即可关闭bin日志的记录。
一个客户的数据库,积累了大量的bin日志:
