phpmyadmin 链接远程mysql
这个只是自己的笔记 新手 不记下来以后又忘记了~
在这以前已经给mysql设置了可以远程连接的账户
版本 phpMyAdmin-4.2.11-all-languages
解压到D盘下www 本地环境包
解压完了 找到 phpMyAdmin\libraries 下面的config.default.php
$cfg['Servers'][$i]['host'] = '自己的IP 家里的 一般都是花生壳的域名';//默认localhost
$cfg['Servers'][$i]['port'] = '3306';//端口什么的自己对应
$cfg['Servers'][$i]['auth_type'] = 'http';//默认是cookie
远程设置完毕 登录测试 完成 没有问题啦~ 以后省得自己老要查找了~
服务器上的mysql 要有远程权限
红色的为登录账号密码 phpmyadmin下修改方法 直接切换sql下
GRANT ALL PRIVILEGES ON *.* TO xxx@'%' IDENTIFIED BY '123456' WITH GRANT OPTION
如下图
要是不行 路由器里3306 等端口 进行端口映射
MYSQL控制台添加远程登录账号
mysql> grant all privileges on *.* to 'root'@'112.74.176.123' identified by 'xc15801654323' with grant option;

2. mysql 2003报错 ERROR 2003 (HY000): Can't connect to MySQL server on 'xxx.xxx.xxx.xxx' (10060)
wdlinux环境里 service iptables stop || service iptables start
添加规则：
vi /etc/sysconfig/iptables
-A INPUT -p tcp -m state --state NEW -m tcp --dport 3306 -j ACCEPT
ESC - [:wq]
service iptables stop
service iptables start
未解决问题：
1.如何判断是哪个防火墙
2.配置文件如何查找
常用命令：
service iptables status
