mysql不能从其他机器连接解决总结_MySQL
bitsCN.com
最近在配置mysql的时候遇到了各种问题，现在归纳总结一下。
mysql安装完毕以后，本机可以连接，但是其他机器不行，连不上，原因有以下几个：
1 权限问题，可以用grant给某个用户分配权限，比如localhost/某些ip地址等等，具体可以搜索“mysql grant”，资料也很多，这里就不展开了
2 防火墙问题。RHEL系统的防火墙在安装的时候是默认打开的，这样其他机器连这台的mysql就会被拒绝，最简单的办法就是把防火墙关掉。（切换到root用户，输入setup，进入服务器配置界面，选择“Firewall configuration”，把Firewall: [＊] Enabled 的星号去掉，保存，退出）
3 绑定ip的问题。Ubuntu server系统安装的mysql，在my.cnf配置文件里面是有个bind ip选择项，如果bind ip=127.0.0.1 或者这里的ip和你当前机器的ip不一样，就会造成mysql不能被其他机器连接，解决方法是注释掉bind ip这行，或者把ip写正确。
