[Q1] 解决mysql远程登录
一、确认服务器端口号开放
1、确认3306端口是否对外开放
ubuntu@ubuntu:~$ netstat -an | grep 3306 tcp0 0 127.0.0.1:3306 0.0.0.0:* LISTEN
此处3306端口只监听本地的(127.0.0.1)连接,修改/etc/mysql/my.cnf中的bind-address,注释掉或者改成指定的IP
二、授权远程连接用户<br>
1、登录:
mysql -uroot -pxxxx
2、授权
grant all privilege on [database].[table] to [user]@[ip] identified by [password] mysql>grant all on *.* to user_name@‘%‘ identified by ‘user_password‘;
database:授权的数据库名,所有的数据库用匹配符`*`<br>
table:授权的表名,所有的表用匹配符`*`<br>
user:授权的用户名<br>
ip:授权的ip地址,例如 ‘xxx.xxx.xxx.xxx‘
password:授权用户名的密码,例如 ‘xxxxxx‘
3、刷新授权或者mysql重启
flush privilege sudo /etc/init.d/mysql restart
