1、官方安装文档
http://dev.mysql.com/doc/mysql-yum-repo-quick-guide/en/
2、下载 Mysql yum包,官方链接,可自行选择版本
http://dev.mysql.com/downloads/repo/yum/
下载到本地再上传到服务器,或者使用wget 直接下载
wget http://repo.mysql.com/mysql57-community-release-el7-10.noarch.rpm
3、安转软件源
将mysql57-community-release-el7-10.noarch.rpm
替换为你下载的rpm名
sudo rpm -Uvh mysql57-community-release-el7-10.noarch.rpm
4、安装mysql服务端(这里可能要很久,网速不好的话)
yum install -y mysql-community-server
5、启动mysql
service mysqld start
systemctl start mysqld.service
6、接着检查mysql 的运行状态
service mysqld status
之后与如下提示,说明启动成功了
[root@localhost Desktop]# service mysqld status
Redirecting to /bin/systemctl status mysqld.service
● mysqld.service - MySQL Server

7、修改临时密码
Mysql5.7默认安装之后root是有密码的。
7.1 获取MySQL的临时密码
为了加强安全性,MySQL5.7为root用户随机生成了一个密码,在error log中,关于error log的位置,如果安装的是RPM包,则默认是/var/log/mysqld.log。
只有启动过一次mysql才可以查看临时密码
如果之前安装过MySQL则这里可能会有多个密码,用最后一个,注意这个密码输入时是可以粘贴的
grep 'temporary password' /var/log/mysqld.log
如:
[root@localhost Desktop]# grep 'temporary password' /var/log/mysqld.log
2019-03-13T07:37:54.834875Z 1 [Note] A temporary password is generated for root@localhost: Z5j&8Bv>&m9a
我的密码就是:Z5j&8Bv>&m9a
7.2 登陆并修改密码
mysql -uroot -pZ5j&8Bv>&m9a
修改密码(注意,登录后的操作后面都最好要有;结尾)
ALTER USER 'root'@'localhost' IDENTIFIED BY '111111';
如果密码设置太简单出现以下的提示如下:
mysql> ALTER USER 'root'@'localhost' IDENTIFIED BY '111111';
ERROR 1819 (HY000): Your password does not satisfy the current policy requirements
如何解决ERROR 1819 (HY000): Your password does not satisfy the current policy requirements呢?
必须修改两个全局参数:
首先,修改validate_password_policy参数的值
mysql> set global validate_password_policy=0;
再修改密码的长度
set global validate_password_length=1;
再次执行修改密码就可以了
ALTER USER 'root'@'localhost' IDENTIFIED BY '111111';
8、授权其他机器登陆或其他地方登录如:Navicat
注意: 后面对密码一定不能错,需要根据具体的做修改
GRANT ALL PRIVILEGES ON *.* TO 'root'@'%' IDENTIFIED BY '111111' WITH GRANT OPTION;
FLUSH PRIVILEGES;
