Ubuntu 安装 mysql

参考教程:

Ubuntu18.04 安装MySQL

1. 安装 MySQL

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

UbuntuMySQL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;
