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 passwordpassword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
