安装Linux版MySql教程,命令行操作

 

2018更新

ubuntu最新安装可按照此步骤:

1.安装mysql

#命令1
sudo apt-get update
#命令2
sudo apt-get install mysql-server

输入Y确认,中间会弹出让输入root用户密码,输入一遍下一步再输入确认一遍;


2.配置mysql

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)
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)


3.检查mysql服务状态

systemctl status mysql.service
看到active(running)字样证明启动正常



4.配置远程访问

先去 /etc/mysql/my.cnf 或者 /etc/mysql/mysql.conf.d/mysqld.cnf 找到如下配置项:

bind-address            = 127.0.0.1
修改为:

bind-address            = 0.0.0.0


然后进入mysql

mysql -u root -p password
password为安装步骤时你设置的root密码

grant all privileges on *.* to root@"%" identified by "password" with grant option; 
password同上,然后依次执行如下命令:

flush privileges;

exit

/etc/init.d/mysql restart 





结束,旧版 ubuntu 或 CentOS6 参考如下安装
