• 下載MySQL yum源

wget https://dev.mysql.com/get/mysql80-community-release-el7-1.noarch.rpm

• 安裝yum源

yum localinstall mysql80-community-release-el7-1.noarch.rpm

• 更新yum源

yum clean all
yum makecache

• 建立Mysql帳戶

groupadd mysql
useradd -g mysql mysql

• 開始安裝MySQL

yum install mysql-community-server

• 啓動MySQL

systemctl  start  mysqld

• 查看初始化密碼

cat /var/log/mysqld.log | grep password

• 登陸MySQL

mysql -u root -p

• 修改初始化密碼（密碼必定要大小寫字母+數字+符號，如：Aa-123456789）

ALTER USER 'root'@'localhost' IDENTIFIED BY 'yourpassword';

• 遠程設置

use mysql;
update user set host='%' where user='root';

• 容許任何主機訪問數據庫

GRANT ALL PRIVILEGES ON *.* TO 'root'@'%'WITH GRANT OPTION;
FLUSH PRIVILEGES;

• 容許myuser用戶使用mypassword密碼從任何主機鏈接到mysql服務器

GRANT ALL PRIVILEGES ON *.* TO 'myuser'@'%'IDENTIFIED BY 'mypassword' WITH GRANT OPTION;

• 容許用戶myuser從ip爲192.168.1.6的主機鏈接到mysql服務器，並使用mypassword做爲密碼

GRANT ALL PRIVILEGES ON *.* TO 'myuser'@'192.168.1.3'IDENTIFIED BY 'mypassword' WITH GRANT OPTION;

報錯備註

ERROR 1045 (28000): Access denied for user 'root'@'localhost' (using password: YES)

解決：/etc/my.cnf 下[mysqld]後添加 skip-grant-tables

ERROR 1290 (HY000): The MySQL server is running with the --skip-grant-tables option so it cannot execute this statement

解決：刷新權限：flush privileges;
