搭建备份到业务迁移---mysql

mysql安装启动以及配置

使用到阿里云主机直接yum安装以及配置

[root@yunwei-169 mysql]# yum install mysql  mysql-server

[root@yunwei-169 mysql]# mysql -V
mysql  Ver 14.14 Distrib 5.1.73, for redhat-linux-gnu (x86_64) using readline 5.1
[root@yunwei-169 mysql]# 
　　
安装这版本默认没有密码直接启动服务,创建abc用户，赋予所有库和表到权限
[root@yunwei-169 mysql]# /etc/init.d/mysqld start
[root@yunwei-169 mysql]# mysql -h 127.0.0.1 -uroot 
mysql>  update  mysql.user  set password=PASSWORD("youpassword")  where user="root";
mysql> select user,host,password from mysql.user;
+-------+------------+-------------------------------------------+
| user  | host       | password                                  |
+-------+------------+-------------------------------------------+
| root  | localhost  | *011BD6B76D153FF40E1B332A525F208A510B4297 |
| root  | yunwei-169 | *011BD6B76D153FF40E1B332A525F208A510B4297 |
| root  | 127.0.0.1  | *011BD6B76D153FF40E1B332A525F208A510B4297 |
|       | localhost  |                                           |
|       | yunwei-169 |                                           |
+-------+------------+-------------------------------------------+
6 rows in set (0.00 sec)

mysql> create user 'abc'@'%' IDENTIFIED BY 'password';
mysql> grant all privileges on *.* to  'abc'@'%';  #给予操作权限
mysql>flush privileges;­ #刷新权限使其生效

本地业务迁移前数据库是通过mysqldump –all-databases -h127.0.0.1 -uroot -pxxxxx> xxx.sql 的方式备份的数据

然后数据库创建导入

[mysql]> create database abc;
[mysql]>use adb;
[mysql]>set names utf8;
[mysql]>source /xxx.sql；

给新的web后台和本地维护添加权限

导入方式2:

 mysql -h127.0.0.1 -uxxx -pxxx tablename </tmp/aaa.sql &
