Centos6.4乘64编译安装MYSQL5.6.12教程(2)

1.# vim /etc/profile

在55行export PATH 。。。后刺进
export PATH=$PATH:/usr/local/mysql/bin

view sourceprint?

1.# source /etc/profile

5、执行MySQL安全脚本

view sourceprint?

1.# mysql_secure_installation

NOTE: RUNNING ALL PARTS OF THIS SCRIPT IS RECOMMENDED FOR ALL MySQL
SERVERS IN PRODUCTION USE！ PLEASE READ EACH STEP CAREFULLY！
In order to log into MySQL to secure it，we’ll need the current
passwordfor the root user. If you’ve just installed MySQL，and
you haven’t set the root passwordyet，the password will be blank，
so you should just press enter here.
Enter current password for root (enter for none):<--假如设置了mysql的root暗码，需要在这输入
OK，successfully used password，moving on…
Setting the root password ensures that nobody can log into the MySQL
root user without the proper authorisation.
Set root password[Y/n] <-- 是否设置root暗码
New password: <-- 设置一个用户暗码
Re-enter new password: <-- 再输入一次你设置的暗码
Password updated successfully！
Reloading privilege tables..
… Success！
By default，a MySQL installation has an anonymous user，allowing anyone
to log into MySQL without having to have a user account created for
them. This is intended only for testing，and to make the installation
go a bit smoother. You should remove them before moving into a
production environment.
Remove anonymous users[Y/n] <-- 是否移除匿名用户
… Success！
Normally，root should only be allowed to connect from ’localhost’. This
ensures that someone cannot guess at the root password from the network.
Disallow root login remotely[Y/n] <--是否封闭root长途登录
… Success！
By default，MySQL comes with a database named ’test’ that anyone can
access. This is also intended only for testing，and should be removed
before moving into a production environment.
Remove test database and access to it[Y/n] <-- 是否删去test数据库
- Dropping test database…
… Success！
- Removing privileges on test database…
… Success！
Reloading the privilege tables will ensure that all changes made so far
will take effect immediately.
Reload privilege tables now[Y/n] <-- 是否重新载入权限表
… Success！
Cleaning up…
All done！ If you’ve completed all of the above steps，your MySQL
installation should now be secure.
Thanks for using MySQL！

假如不执行安全脚本也能够做下面设置

1、为root帐户设置初始暗码

view sourceprint?

1.# /usr/local/mysql/bin/mysqladmin -u root password 'new-password'

2、删去本机匿名衔接的空暗码帐号

view sourceprint?

1.# mysql -uroot -p

view sourceprint?

1.mysql>use mysql; //选择默认数据库mysql

2.mysql>update usersetpassword='root123' where user = '127.0.0.1';

3.mysql>delete from user where password="";//不答应root暗码为空
