尝试连接到远程MySQL主机(错误2003)
我有一个在Debian服务器上运行的MySQL实例,可以毫无问题地本地连接到它。但是,我无法远程连接到它。当我从命令行尝试此操作时,出现以下错误:
ERROR 2003 (HY000): Can't connect to MySQL server on '<server-ip>' (110)
我已将用户添加为mysql,分别为“ user’@’*’和’user’@’localhost”。该服务器中的skip-
networking设置为false,并且my.cnf中注释了绑定地址。我还尝试使用以下命令在iptables中打开端口3306:
/sbin/iptables -A INPUT -i eth0 -p tcp --destination-port 3306 -j ACCEPT
这是我所有的iptable防火墙规则的清单,我使用iptables -L检索了这些规则:
Chain INPUT (policy DROP)target prot opt source destination
ACCEPT all -- anywhere anywhere
REJECT tcp -- anywhere anywhere tcp dpt:auth reject-with icmp-port-unreachable
ACCEPT icmp -- anywhere anywhere icmp type 8 code 0 state NEW,RELATED,ESTABLISHED,UNTRACKED

ACCEPT tcp -- anywhere anywhere tcp dpt:mysql
LOG tcp -- anywhere anywhere tcp dpt:mysql LOG level debug
Chain FORWARD (policy ACCEPT)
target prot opt source destination
Chain OUTPUT (policy ACCEPT)
target prot opt source destination
有谁知道我应该从这里去哪里?
回答:
根据您的响应,您需要查找您与服务器之间是否存在阻止连接的设备。你也应该保证你可以telnet到3306上该服务器的以太网地址 时,登录到服务器
…如果不是,你可能还没有得到在绑定以太网服务my.cnf
…看bind-address
参数。
