CentOS7 下的mysql安装与配置
之前虽然也安装过多次mysql,但每次都会遇到各种小问题,这次记录下来,以备后查。
首先是下载与安装
# wget http://dev.mysql.com/get/mysql-community-release-el7-5.noarch.rpm
# rpm -ivh mysql-community-release-el7-.noarch.rpm
# yum install mysql-community-server
安装过程中间会出现选择y/n的,直接输入y即可,如下:

[root@APP1 /]# wget http://dev.mysql.com/get/mysql-community-release-el7-5.noarch.rpm

设置密码
mysql> set password for 'root'@'localhost'=password('password');
Query OK, rows affected (0.00 sec) mysql> exit

配置编码格式
mysql> default-character-set =utf8
->
设置允许远程连接
mysql> grant all privileges on *.* to root@'%'identified by 'password';
Query OK, rows affected (0.00 sec) mysql>
如果允许root账号远程连接要对系统数据库的root账户设置远程访问的密码,与本地的root访问密码并不冲突。
1 grant all privileges on *.* to 'root'@'%' identified by '123456' with grant option; #123456为你需要设置的密码
