ubuntu上mysql服务器安装后只能本地连接不能远程连接的问题

  •  进行授权

 (1)直接授权

mysql>GRANT ALL PRIVILEGES ON *.* TO ‘root‘@‘%‘ IDENTIFIED BY ‘123456‘ WITH GRANT OPTION;
mysql>FLUSH RIVILEGES

  (2)改表法 可能是你的帐号不允许从远程登陆,只能在localhost。这个时候只要在localhost的那台电脑,登入mysql后,更改 “mysql” 数据库里的 “user” 表里的 “host” 项,从”localhost”改成”%”

mysql -u root -p passwd 
mysql>use mysql;
mysql>update user set host = ‘%‘ where user = ‘root‘;
mysql>select host, user from user;
但是在进行第一步的时候,my.cnf里的内容确却是如下这样的:
#

# The MySQL database server configuration file.

#

# You can copy this to one of:

# - "/etc/mysql/my.cnf" to set global options,

# - "~/.my.cnf" to set user-specific options.

# 

# One can use all long options that the program supports.

# Run program with --help to get a list of available options and with

# --print-defaults to see which it would actually understand and use.

#

# For explanations see

# http://dev.mysql.com/doc/mysql/en/server-system-variables.html

 

#

# * IMPORTANT: Additional settings that can override those from this file!

#   The files must end with ‘.cnf‘, otherwise they‘ll be ignored.

#


!includedir /etc/mysql/conf.d/

!includedir /etc/mysql/mysql.conf.d/

 最后发现,需要修改 的是  /etc/mysql/mysql.conf.d/mysqld.cnf

   使用 sudo vim /etc/mysql/mysql.conf.d/mysqld.cnf

   然后重启mysql服务即可: sudo /etc/init.d/mysql restart
