Unbutu18.10 安装mysql

目录

 

1 安装MySQL

2 进入mysql

3 远程Navicat连接mysql


1 安装MySQL

  • sudo apt-get update
  • sudo apt-get install mysql-server 
  • sudo mysql_secure_installation

接下来认真看提示,按照下面进行配置:

VALIDATE PASSWORD PLUGIN can be used to test passwords…
Press y|Y for Yes, any other key for No: N
Please set the password for root here…
New password: (输入密码)
Re-enter new password: (重复输入)
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
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
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
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

2 进入mysql

  • sudo mysql -uroot -p

   使用如下命令修改root密码

  • update mysql.user set authentication_string=PASSWORD('你要修改的密码'), plugin='mysql_native_password' where user='root';
  • flush privileges;

  此时通过mysql -u root -p 免sudo登录mysql了

3 远程Navicat连接mysql

使用命令退出mysql

  • mysql>exit;

使用如下命令进入mysqld.cnf,注释bind-address = 127.0.0.1

  • sudo vim /etc/mysql/mysql.conf.d/mysqld.cnf
