使用xshell6远程控制服务器安装mysql

是用xshell6远程控制服务器安装mysql

 

可以从官网上下载http://dev.mysql.com/downloads/repo/yum/ 

也可以shell> wget http://dev.mysql.com/get/mysql57-community-release-el7-11.noarch.rpm

可以用linux指令查看是否下载成功 ls -l

3.安装mysql源 shell> yum localinstall mysql57-community-release-el7-11.noarch.rpm

下载和安装过程中会提示是否继续,输入y Enter继续。

4.检查mysql源是否安装成功 shell> yum repolist enabled | grep "mysql.*-community.*"

shell> yum install mysql-community-server

安装mysql服务完成之后启动mysql服务

shell> systemctl start mysqld

然后就可以查看MySQL的启动状态了。shell > systemctl status mysqld

Active:active(running)表示MySQL服务已经启动

设置开机启动

shell > systemctl enable mysqld

shell > systemctl daemon-reload

如果在启动mysql服务的时候出现

Failed to issue method call: Unit mysql.service failed to load: No such file or directory. See system logs and 'systemctl status mysql.service' for details.

的报错信息,则可能是系统权限的问题,shell > chown -r mysql:mysql /var/lib/mysql/  进行授权

shell > rpm -qa | grep -i mysql 可以查看已安装了的mysql组件

mysql安装完成之后,在/var/log/mysqld.log文件中给root生成了一个默认密码。通过下面的方式找到root默认密码,然后登录mysql进行修改:

shell > grep 'temporary password' /var/log/mysqld.log 

mysql > alter user 'root'@'localhost' identified by 'mysqlpassword'; 或 set password for 'root'@'localhost'=password('mysqlpassword');

注意:mysql5.7默认安装了密码安全检查插件(validate_password),默认密码检查策略要求密码必须包含:大小写字母、数字和特殊符号,并且长度不能少于8位。否则会提示ERROR 1819 (HY000): Your password does not satisfy the current policy requirements错误

如果想修改简单易记些的MySQL密码,可以在/etc/my.cnf文件添加validate_password_policy配置,指定密码策略,或直接禁用密码策略,添加 validate_password = off

重新启动(mysql > systemctl restart mysql) mysql服务使配置生效。

 

重置密码

ALTER USER USER() IDENTIFIED BY 'Xiaoming250';
