ubuntu mysql安装目录_ubuntu下安装mysql(二进制)到自定义目录

本文详细介绍了如何通过MySQL命令行工具安全地配置root用户的密码,并移除匿名用户及测试数据库,确保MySQL的安全性。此外,还提供了将MySQL路径添加到环境变量中的步骤。

Enter current password for root (enter for none):

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] y

New password:

Re-enter new password:

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] y

... 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] y

... 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] y

- 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] y

... Success!

三,便利设置

1,将mysql的路径加到环境变量中去:

sudo gedit /etc/profile

然后加入:

1, export MYSQL_HOME=home/user/mysql;

2,在PATH=XX后面加入 :$MYSQL_HOME/bin
