ubuntu安装mysql
今天突然想起来之前的阿里云送的机子还没用，留着可就浪费了=，=
1.使用apt源安装
sudo apt-get install mysql-server
2.对mysql初始化配置
sudo mysql_secure_installation
#1 是否需要检查验证密码
VALIDATE PASSWORD PLUGIN can be used to test passwords...
Press y|Y for Yes, any other key for No: N (我的选项)
#2 输入root密码
Please set the password for root here...
New password: (输入密码)
Re-enter new password: (重复输入)
#3 是否需要安装一个匿名用户
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...
Remove anonymous users? (Press y|Y for Yes, any other key for No) : N (我的选项)
#4 root账号是否开启远程登录权限
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) : Y (我的选项)
#5 是否删除Test数据库
By default, MySQL comes with a database named 'test' that
anyone can access...
Remove test database and access to it? (Press y|Y for Yes, any other key for No) : N (我的选项)
#6 是否重新加载特权表
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) : Y (我的选项)
