不能让它工作。这是我到目前为止所做的：
mysql> CREATE USER 'admin'@'localhost' IDENTIFIED BY 'xxxxxx';
mysql> GRANT ALL PRIVILEGES ON *.* TO 'admin'@'localhost' WITH GRANT OPTION;
mysql> CREATE USER 'admin'@'%' IDENTIFIED BY 'xxxxxx';
mysql> GRANT ALL PRIVILEGES ON *.* TO 'admin'@'%' WITH GRANT OPTION;
在 AWS 控制台 -> EC2 -> 网络和安全 -> 安全组 -> quick-start-1 -> 入站选项卡 -> 从下拉列表中选择“MYSQL” -> 添加规则 -> 应用
编辑/etc/my.cnf并添加bind-address，然后
sudo /etc/init.d/mysqld restart
sudo /sbin/iptables -A INPUT -i eth0 -p tcp --destination-port 3306 -j ACCEPT
sudo service iptables save
最后从我的电脑：
[nir@dhcppc4 ~]$ mysql -h xxx.xxx.xxx.xxx -u admin -p
Enter password:
ERROR 2003 (HY000): Can't connect to MySQL server on 'xxx.xxx.xxx.xxx' (113)
编辑：
运行netstat -lp | grep mysql（我没有在输出中看到端口号）：
tcp 0 0 *:mysql *:* LISTEN -
unix 2 [ ACC ] STREAM LISTENING 16003 - /var/lib/mysql/mysql.sock
添加在/etc/my.cnf
port=3306
现在netstat -lp | grep mysql是
tcp 0 0 *:mysql *:* LISTEN -
unix 2 [ ACC ] STREAM LISTENING 37757 - /var/lib/mysql/mysql.sock
/etc/my.cnf文件：
[mysqld]
datadir=/var/lib/mysql
socket=/var/lib/mysql/mysql.sock
user=mysql
port=3306
bind-address = 0.0.0.0
#skip-networking
# 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
另外我尝试通过其他计算机连接，但我无法连接，所以我想这不是连接计算机的问题
我的 telnet 被拒绝访问：
[nir@dhcppc4 ~]$ telnet xxx.xxx.xxx.xxx 3306
Trying xxx.xxx.xxx.xxx...
telnet: connect to address xxx.xxx.xxx.xxx: No route to host
** 我也在尝试在亚马逊 ec2 论坛中解决它
