不好意思，现在看是有错误日志的。我尝试过从 bin_log 文件的第一个位置开始同步，和最新的主库的位置开始同步都没成功 。
[Warning] Neither --relay-log nor --relay-log-index were used; so replication may break when this MySQL server acts as a slave and has his hostname changed!! Please use '--relay-log=localhost-relay-bin' to avoid this problem.
[Warning] Storing MySQL user name or password information in the master info repository is not secure and is therefore not recommended. Please consider using the USER and PASSWORD connection options for START SLAVE; see the 'START SLAVE Syntax' in the MySQL Manual for more information.
