我的Mysql环境是ubuntu+mysql5
1.修改/etc/mysql/my.conf,修改bind-address,指定为本机实际IP地址，你的my.con修改完大概是如下的样子
[mysqld]
#
# * Basic Settings
#
default-character-set=utf8
default-storage-engine=INNODB
bind-address = 192.168.1.107
user = mysql
pid-file = /var/run/mysqld/mysqld.pid
socket = /var/run/mysqld/mysqld.sock
port = 3306
basedir = /usr
datadir = /var/lib/mysql
tmpdir = /tmp
language = /usr/share/mysql/english
skip-external-locking
2.用root登陆mysql执行如下命令
grant all on sonardb.* to sonar@'%' identified by '123456';
grant all on sonardb.* to sonar@localhost identified by '123456';
sonardb替换为你想访问的数据库名，sonar是你的想使用的用户名，123456替换为你的密码，这样就开启了远程访问功能。
