Amazon EC2 上的 MySQL 数据库复制错误 2013

Question

我目前在尝试使用 redhat os 在亚马逊 EC2 上创建 mysql 主/从服务器时遇到问题。在大多数情况下，我都遵循本教程 (http://www.howtoforge.com/how-to-set-up-mysql-database-replication-on-fedora-10)。

当调用 SHOW SLAVE STATUS\G;我明白了：

我的奴隶 my.cnf

# Disabling symbolic-links is recommended to prevent assorted security risks
symbolic-links=0

[mysqld_safe]
log-error=/var/log/mysqld.log
pid-file=/var/run/mysqld/mysqld.pid

和我的主人 my.cnf

[mysqld]

log-bin = /var/log/mysql/mysql-bin.log
binlog-do-db=mosaicschroma
server-id=1

datadir=/var/lib/mysql
socket=/var/lib/mysql/mysql.sock
user=mysql
# Disabling symbolic-links is recommended to prevent assorted security risks
symbolic-links=0

[mysqld_safe]
log-error=/var/log/mysqld.log
pid-file=/var/run/mysqld/mysqld.pid

当使用 nmap 检查我是否可以 ping 另一台服务器和端口 3306 时，我收到一个过滤报告，我认为这是正确的。

非常感谢任何帮助，谢谢！

我会先从从机尝试：

telnet master-machine 3306

如果您收到这样的 mysql 乱码消息，则说明您没有防火墙连接问题：

Trying 127.0.0.1...
Connected to 127.0.0.1.
Escape character is '^]'.
N
5.5.34-log>W~4%]$�>eb;>gi\rGK#mysql_native_password

也像grossvogel 所说，检查您尝试用于连接到主用户的从属用户的授权。
