安装 mysql
1.下载mysql的repo源
$ wget http://repo.mysql.com/mysql-community-release-el7-5.noarch.rpm
2.安装mysql-community-release-el7-5.noarch.rpm包
$ sudo rpm -ivh mysql-community-release-el7-5.noarch.rpm
安装这个包后,会获得两个mysql的yum repo源:/etc/yum.repos.d/mysql-community.repo,/etc/yum.repos.d/mysql-community-source.repo。
3.安装mysql
$ sudo yum install mysql-server
根据提示安装就可以了,不过安装完成后没有密码,需要重置密码
4.重置mysql密码
$ mysql -u root
登录时有可能报这样的错:ERROR 2002 (HY000): Can‘t connect to local MySQL server through socket ‘/var/lib/mysql/mysql.sock‘ (2),原因是/var/lib/mysql的访问权限问题。下面的命令把/var/lib/mysql的拥有者改为当前用户:
$ sudo chown -R root:root /var/lib/mysql
重启mysql服务
$ service mysqld restart
接下来登录重置密码:
$ mysql -u root //直接回车进入mysql控制台
mysql > use mysql;
mysql > update user set password=password('123456') where user='root';
mysql > exit;
导入导出操作:
mysqldump -uroot -p123456 databse.table > xxx.file
mysqlimport -uroot -p123456 test xddd.file
mysql source xxx.sql 导入文件
