阿里雲伺服器安裝MySQL 8.0 (GA)

一. MySQL官方地址 MySQL Yum倉庫的RPM安裝包

這裡寫圖片描述

通過wget方式獲取yum包

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

這裡寫圖片描述

二. 安裝MySQL RPM安裝包

命令：

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

這裡寫圖片描述

看到安裝MySQL8.0安裝完成後可到/etc/yum.repos.d/目錄下看到：

mysql-community.repo
mysql-community-source.repo

兩個檔案,說明MySQL Yum倉庫新增成功。

三. 安裝MySQL

Complete!

完成之後資料庫會有一個初始密碼，可通過一下命令檢視：

[root@*******2dru8ftg3uz log]# sudo grep 'temporary password' /var/log/mysqld.log

這裡寫圖片描述

至此，MySQL8.0 安裝完成，下面進行啟動配置。

四、啟動MySQL8.0

##啟動MySQL服務
[[email protected]**********2dru8ftg3uz log]# sudo service mysqld start

##停止MySQL服務：service mysqld stop

五、進行一些必要的配置

1、修改初始密碼

##檢視預設密碼
shell> sudo grep 'temporary password' /var/log/mysqld.log
##使用預設密碼登陸
shell> mysql -uroot -p
#MySQL8.0修改密碼需要有大小寫字母、數字、特殊字元組合
mysql> ALTER USER 'root'@'localhost' IDENTIFIED BY 'MyNewPass4!';

官方給出的密碼修改說明：
這是官方

#預設情況下密碼策略要求密碼至少包含一個大寫字母、一個小寫字母、一個數字和一個特殊字元，並且總密碼長度至少為8個字元。
否則回報出：ERROR 1819 (HY000): Your password does not satisfy the current policy requirements

validate_password is installed by default. The default password policy implemented by validate_password requires that passwords contain at least one upper case letter, one lower case letter, one digit, and one special character, and that the total password length is at least 8 characters.

2、外網/客戶端訪問問題

客戶訪問報錯:ERROR 1130: Host '192.168.1.3' is not allowed to connect to this MySQL

解決方案：
    服務端登陸MySQL，修改user表登陸使用者的host。
