Ubuntu 安装 mysql
Ubuntu 安装 mysql
参考教程:
1. 安装 MySQL
在Ubuntu
中,默认情况下,只有最新版本的MySQL
包含在APT
软件包存储库中,要安装它,只需更新服务器上的包索引并安装默认包apt-get
。
(base) simulate@simulate-VirtualBox:~$ sudo apt-get update
(base) simulate@simulate-VirtualBox:~$ sudo apt-get install mysql-server
2. 配置 MySQL
2.1 初始化配置
(base) simulate@simulate-VirtualBox:~$ sudo mysql_secure_installation
配置项较多,如下所示:
#1
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
Please set the password for root here...
New password: (输入密码:666)
Re-enter new password: (重复输入:666)
#3
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
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
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
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)
2.2 检查 mysql 服务状态
(base) simulate@simulate-VirtualBox:~$ systemctl status mysql.service
显示如下结果说明mysql
服务是正常的:
3. 配置远程访问
在Ubuntu
下MySQL
缺省是只允许本地访问的,使用workbench
连接工具是连不上的;
如果你要其他机器也能够访问的话,需要进行配置;
(base) simulate@simulate-VirtualBox:~$ sudo mysql -uroot -p
登入root
进行其他设置:
设置用户名:root,密码:666
mysql> update mysql.user set authentication_string=PASSWORD('666'), plugin='mysql_native_password' where user='root';
mysql> create user 'root'@'%' identified by '666';
mysql> grant all on *.* to 'root'@'%';
mysql> flush privileges;
