【problem appear】

Remote access is not enabled by default

It will prompt MySQL error: Can't connect to MySQL server (10060/1) error[1], we need to start from the following aspects: [Solution]

1. Any remote host can access the database  

     //[Explanation] Allow root user to access all databases with any IP address

mysql> GRANT ALL PRIVILEGES ON *.* TO 'root'@'%'WITH GRANT OPTION;

    

    //You need to enter the update command to make the changes take effect

mysql> FLUSH PRIVILEGES;      

    //quit

mysql> EXIT     

 

 

2. Modify the mysql configuration file my.cnf under the ubantu server.

     //The default binding is bind-address = 127.0.0.1, which needs to be modified

# sudo vim /etc/mysql/my.cnf    

      Comment out bind-address = ******** and add # before the sentence 

      Add the following two sentences:

          skip-external-locking

          skip-name-resolve

 

     // restart mysql

#sudo  service mysql restart 

 Usually the problem is solved in the second step.

 

3、sudo apt-get install mysql-server mysql-client[2]组件安装全。

 

4、关闭防火墙，或者是添加好3306端口的开放。[3]

#/sbin/iptables -I INPUT -p tcp --dport 3306 -j ACCEPT

 #/etc/rc.d/init.d/iptables save  保存：

  # service iptables restart 重启生效

 或者 /sbin/iptables-save 

 

当然除了开放3306端口外，还有一个方法就是关闭防火墙，命令为：

  # service iptables stop 

 

5、添加访问允许

/etc/hosts.allow [4]

mysqld : ALL : ALLOW

mysqld-max : ALL :ALLOW

 

修改/etc/hosts.allow和/etc/hosts.deny允许linux服务器允许和限制访问

 

对于能过xinetd程序启动的网络服务，比如ftp telnet，我们就可以修改/etc/hosts.allow和/etc/hosts.deny的配置，来许可或者拒绝哪些IP、主机、用户可以访问。
