我们最近对我们的基础设施进行了一些更改，现在我无法保持 MySQL 复制运行。奴隶抱怨二进制日志损坏，重置它无济于事。我一直在我的主日志中看到这样的条目：
二进制日志' WFxKTRNJAAAAPwAAAKY/YwAAABsAAAAAAAEACHdlYmVkaTMwAA1QYXJ0bmVyQ29uZmlnAAQICA8P BC0AYwAA WFxKTRhJAAAAXAAAAAAJAYwAAABsAAAAAAAEABP//8BoSAAAAAAAAAAggMAAAAAAAAJUEFDS0NPVU5U Azc3MfAaEgAAAAAAAIIDAAAAAAAACVBBQ0tDT1VOVAM3NzI= '/*!*/;
在从属日志中，这只是作为“未知事件”出现，并且复制在该位置失败。
这是我给主人的 my.cnf：

我在 ubuntu 机器上运行了 mysql-5.1.41 master-master 设置，下面是 master 的配置：
skip-host-cache
skip-name-resolve
event_scheduler = ON
max_connections = 500
max_connect_errors = 1000
server-id = 10
replicate-same-server-id = 0
auto-increment-increment = 10
auto-increment-offset = 1
master-host = 192.168.1.106
master-user = repli
master-password = secret
master-connect-retry = 60
binlog-format = MIXED
binlog-ignore-db = information_schema
binlog-ignore-db = lb1
log-bin = /var/log/mysql/mysql-bin
log-bin-index = /var/log/mysql/bin-log.index
log-slave-updates
report-host = 192.168.1.105
replicate-ignore-db = information_schema
replicate-ignore-db = lb2
relay-log = /var/log/mysql/relay.log
relay-log-index = /var/log/mysql/relay-log.index
日志文件似乎每天都在增长。有谁知道我应该在上面的配置中包含什么参数来自动删除/刷新旧的不必要的日志，并具有适当的值，不会损坏同步？。
