mysql安装

PLEASE REMEMBER TO SET A PASSWORD FOR THE MySQL root USER !
To do so, start the server, then issue the following commands:

/usr/bin/mysqladmin -u root password 'new-password'
/usr/bin/mysqladmin -u root -h BJ-DZM-100.360buy.com password 'new-password'

Alternatively you can run:
/usr/bin/mysql_secure_installation

which will also give you the option of removing the test
databases and anonymous user created by default.  This is
strongly recommended for production servers.

See the manual for more instructions.

Please report any problems with the /usr/bin/mysqlbug script!

/etc/init.d/mysql start

service iptables stop

设置Mysql可以远程访问

错误提示:
ERROR 1130: Host '192.168.1.3' is not allowed to connect to this MySQL server

第一:更改 “mysql” 数据库里的 “user” 表里的 “host” 项,从”localhost”改称'%'。
或者新加条记录,“host” 项为要访问的ip地址,并授权。重启mysql服务。
第二:在系统防火墙添加例外端口:3306,并允许例外。

解决方法:
1。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"改称"%"
1.mysql -u root -pvmware
mysql>use mysql;
mysql>update user set host = '%' where user = 'root';
mysql>select host, user from user;  

2. 授权法。例如,你想myuser使用mypassword从任何主机连接到mysql服务器的话。

GRANT ALL PRIVILEGES ON *.* TO 'myuser'@'%' IDENTIFIED BY 'mypassword' WITH GRANT OPTION;
如果你想允许用户myuser从ip为192.168.1.3的主机连接到mysql服务器,并使用mypassword作为密码
GRANT ALL PRIVILEGES ON *.* TO 'myuser'@'192.168.1.3' IDENTIFIED BY 'mypassword' WITH GRANT OPTION;

3.在window自带的防火墙里的例外添加3306端口

总结:
mysql -u root -p
mysql>use mysql;
mysql>select host from user where user='root';
mysql>update user set host = '%' where user ='root' and host='localhost';
mysql>flush privileges;
mysql>select 'host'   from user where user='root';
第一句是以权限用户root登录
第二句:选择mysql库
第三句:查看mysql库中的user表的host值(即可进行连接访问的主机/IP名称)
第四句:修改host值(以通配符%的内容增加主机/IP地址),当然也可以直接增加IP地址
第五句:刷新MySQL的系统权限相关表
第六句:再重新查看user表时,有修改。。
重起mysql服务即可完成。
