1.确保你的虚拟机能上网
2.我们使用的时yum安装的 下载mysql的repo源
键入如下命令:
$ wget http://repo.mysql.com/mysql-community-release-el7-5.noarch.rpm
[root@slave1 ~]# wget http://repo.mysql.com/mysql-community-release-el7-5.noarch.rpm
--2018-03-15 15:38:59-- http://repo.mysql.com/mysql-community-release-el7-5.noarch.rpm
正在解析主机 repo.mysql.com (repo.mysql.com)... 23.207.113.116

2018-03-15 15:38:59 (293 MB/s) - 已保存 “mysql-community-release-el7-5.noarch.rpm” [6140/6140])
返回200 Ok说明成功
3.安装mysql-community-release-el7-5.noarch.rpm包
$ sudo rpm -ivh mysql-community-release-el7-5.noarch.rpm
[root@slave1 ~]# sudo rpm -ivh mysql-community-release-el7-5.noarch.rpm
准备中... ################################# [100%]
正在升级/安装...
1:mysql-community-release-el7-5 ################################# [100%]
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。
4.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
安装过程中可能会出现如下错误:
[root@slave1 ~]# sudo yum install mysql-server
已加载插件:fastestmirror, langpacks
/var/run/yum.pid 已被锁定,PID 为 3761 的另一个程序正在运行。
Another app is currently holding the yum lock; waiting for it to exit...
另一个应用程序是:PackageKit
内存:114 M RSS (450 MB VSZ)
已启动: Thu Mar 15 15:38:40 2018 - 00:59之前
状态 :睡眠中,进程ID:3761

另一个应用程序是:PackageKit
内存:114 M RSS (450 MB VSZ)
已启动: Thu Mar 15 15:38:40 2018 - 01:01之前

解决办法 你看到这个进程ID 3761
用如下命令:kill -9 强制杀死该命令
[root@slave1 ~]# kill -9 3761
如果问题没有解决多来几次就好了

5.重置mysql密码
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
[root@slave1 ~]# mysql -u root
ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/var/lib/mysql/mysql.sock' (2)
[root@slave1 ~]# sudo chown -R root:root /var/lib/mysql
6.重启mysql服务
$ service mysqld restart
[root@slave1 ~]# service mysqld restart
Redirecting to /bin/systemctl restart mysqld.service
7.再次登陆
[root@slave1 ~]# mysql -u root

8.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('root') where user='root';
mysql > exit;
注意分号结尾
mysql> use mysql

10.其他
Linux下配置Mysql允许远程访问详解
操作非常简单,就5步骤,如下:
1.进入 mysql:
/usr/local/mysql/bin/mysql -u root -p
2.使用 mysql库 :
use mysql;
3.查看用户表 :
SELECT `Host`,`User` FROM user;
4.更新用户表 :
UPDATE user SET `Host` = '%' WHERE `User` = 'root' LIMIT 1;
5.强制刷新权限 :
flush privileges;
完成以上步骤即可远程连接数据库了,上边关键的一句是
UPDATE user SET `Host` = '%' WHERE `User` = 'root' LIMIT 1;
其中%的意思是允许所有的ip远程访问,如果需要指定具体的某个ip就写上具体的ip即可
