一、系统环境
yum update升级以后的系统版本为
[root@yl-web yl]# cat /etc/redhat-release CentOS Linux release 7.1.1503 (Core)
二、mysql安装
# wget http://dev.mysql.com/get/mysql-community-release-el7-5.noarch.rpm # rpm -ivh mysql-community-release-el7-5.noarch.rpm # yum install mysql-community-server
安装成功后重启mysql服务。
初次安装mysql，root账户没有密码。
[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. Oracle is a registered trademark of Oracle Corporation and/or its affiliates. Other names may be trademarks of their respective owners. Type 'help;' or '\h' for help. Type '\c' to clear the current input statement. mysql> show databases; +--------------------+ | Database | +--------------------+ | information_schema | | mysql | | performance_schema | | test | +--------------------+ 4 rows in set (0.01 sec) mysql>
设置密码
mysql> set password for 'root'@'localhost' =password('password'); Query OK, 0 rows affected (0.00 sec) mysql> 不需要重启数据库即可生效。
三、配置mysql
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 'password';
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。
