闲来生雅趣,无事乐逍遥。对窗相望雪,一盏茶香飘。

Linux下允许MySQL被远程访问

#Linux #MySQL


在Windows上安装MySQL,折腾了无数次,随后都是失败。无奈找了一台旧机器装个Linux,运行MySQL。但是却发现,默认的MySQL只能本地访问。

几个核心点

修改bind-address

我的MySQL是通过lnmp安装的,配置文件就在/ets/my.cnf。其他情况请自行查找。

基本原则就是删除“bind-address = ”或者将其设置为“bind-address = 0.0.0.0”

修改iptables

检查iptable

sudo iptables -L --line-numbers
Chain INPUT (policy ACCEPT)
num  target     prot opt source               destination
1    ACCEPT     all  --  anywhere             anywhere
2    ACCEPT     all  --  anywhere             anywhere             state RELATED,ESTABLISHED
3    ACCEPT     tcp  --  anywhere             anywhere             tcp dpt:ssh
4    ACCEPT     tcp  --  anywhere             anywhere             tcp dpt:http
5    ACCEPT     tcp  --  anywhere             anywhere             tcp dpt:https
6    DROP       tcp  --  anywhere             anywhere             tcp dpt:mysql
7    ACCEPT     icmp --  anywhere             anywhere             icmp echo-request

Chain FORWARD (policy ACCEPT)
num  target     prot opt source               destination

Chain OUTPUT (policy ACCEPT)
num  target     prot opt source               destination

注意,是不是有个类似上面6的东西?把它删除了。命令如下:

iptables -D INPUT 6
