ubuntu下安装mysql5.7

下载安装

sudo apt install mysql-server
mysql --version

运行安全脚本 mysql_secure_installation

安全脚本主要做如下事项，根据自己情况设置即可：

• 为root用户设置密码
• 删除匿名账号
• 取消root用户远程登录
• 删除test库和对test库的访问权限
• 刷新授权表使修改生效

lazycece@cc-ubuntu:~$ sudo mysql_secure_installation 

Securing the MySQL server deployment.

Connecting to MySQL using a blank password.

VALIDATE PASSWORD PLUGIN can be used to test passwords
and improve security. It checks the strength of password
and allows the users to set only those passwords which are
secure enough. Would you like to setup VALIDATE PASSWORD plugin?

Press y|Y for Yes, any other key for No: n
Please set the password for root here.

New password: 

Re-enter new password: 
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? (Press y|Y for Yes, any other key for No) : n

 ... skipping.


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? (Press y|Y for Yes, any other key for No) : n

 ... skipping.
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? (Press y|Y for Yes, any other key for No) : n

 ... skipping.
Reloading the privilege tables will ensure that all changes
made so far will take effect immediately.

Reload privilege tables now? (Press y|Y for Yes, any other key for No) : 

 ... skipping.
All done!

初始化数据库

sudo mysqld --initialize

mysql服务操作

service mysql start|stop|restart|reload|force-reload|status
