安装:
yum install -y mysql-server
使用
- 重启: service mysqld restart
初次安装mysql，root账户没有密码。
#进入控制台
[root@yl-web yl]# mysql -u root Welcome to the MySQL monitor. Commands end with ; or \g. Your MySQL connection id is 3 Server version: 5.6.26 MySQL Community Server (GPL) Copyright (c) 2000, 2015, Oracle and/or its affiliates. All rights reserved.

设置密码(不需要重启数据库即可生效)。
mysql> set password for ‘root‘@‘localhost‘ =password(‘123456‘); Query OK, 0 rows affected (0.00 sec) mysql>
配置
mysql配置文件为/etc/my.cnf
1、编码
mysql配置文件为/etc/my.cnf
最后加上编码配置
[mysql] default-character-set =utf8
这里的字符编码必须和/usr/share/mysql/charsets/Index.xml中一致。
2、远程连接设置
把在所有数据库的所有表的所有权限赋值给位于所有IP地址的root用户。
mysql> grant all privileges on *.* to root@‘%‘identified by ‘123456‘;
如果是新用户而不是root，则要先新建用户
mysql>create user ‘username‘@‘%‘ identified by ‘password‘;
此时就可以进行远程连接了。
