MYSQL启动错误之[ERROR] Failed to open log (file './mysql-bin.000039', errno 2)

       今天收到报警说MYSQL的slave挂掉了，检查日志，发现是因为之前搭建主从的时候没有将主库的event传过来，而在主库又更新了event的属性，在参数文件中忽略掉这个错误：

    max_connections = 1000
max_connect_errors = 10
table_open_cache = 8096
#external-locking
max_allowed_packet = 16M
binlog_cache_size = 1M
max_heap_table_size = 8M
sort_buffer_size = 256M
join_buffer_size = 8M
thread_cache_size = 8
slave-skip-errors=1539

 

接着重启数据库，发现启动报错：

160407 17:19:44  InnoDB: Initializing buffer pool, size = 1.0G
160407 17:19:44  InnoDB: Completed initialization of buffer pool

不知道为什么，从库上会报这个错

解决：将从库上的log-bin 注释掉了，重启成功

如果是主库这样做会有风险的
