ubuntu18.04安装mysql
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。
#命令1
sudo apt-get update
#命令2
sudo apt-get install mysql-server
2.配置MySQL
2.1 初始化配置
sudo mysql_secure_installation
#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)
Re-enter new password: (重复输入)
#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
systemctl status mysql.service
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;
3.1 首先用根用户进入
sudo mysql -uroot -p
GRANT ALL PRIVILEGES ON *.* TO [email protected] IDENTIFIED BY "password";
4 修改配置文件
vim /etc/mysql/mysql.conf.d/mysqld.cnf
注释 bind-address
备注:
出现报错client does not support authentication protocol requested by server consider
sudo mysql -uroot -p
ALTER USER 'root'@'localhost' IDENTIFIED WITH mysql_native_password BY 'password';
FLUSH PRIVILEGES;
