**mysql 8.0.18官网源**  
    https://dev.mysql.com/downloads/repo/yum/

找到适合的linux7版本，点击download,跳过打赏  
**右键点击复制下载地址**  
    https://dev.mysql.com/get/mysql80-community-release-el7-3.noarch.rpm

**终端输入**  
 \#> wget https://dev.mysql.com/get/mysql80-community-release-el7-3.noarch.rpm

**安装**  
 \#> yum -y localinstall mysql80-community-release-el7-3.noarch.rpm  
 \#> yum -y install mysql-community-server

**开机启动**  
\# systemctl start mysqld  
\# systemctl enable mysqld  
\# systemctl daemon-reload

**获取临时密码**  
 \#> vim /var/log/mysqld.log

**登录mysql使用mysql库**  
    mysql> use mysql

**允许远程主机，使用用户root登录**  
8.0.18要先新增用户  
    mysql> CREATE USER 'root'@'%' IDENTIFIED BY 'YourPassword';  
    Query OK, 0 rows affected (0.04 sec)

再赋予权限

mysql> grant all privileges on \*.\* to 'root'@'%';  
    Query OK, 0 rows affected (0.03 sec)  
另外，如果远程连接的时候报plugin caching\_sha2\_password could not be loaded这个错误，  
可以尝试修改密码加密插件：

mysql> alter user 'root'@'%' identified with mysql\_native\_password by 'YourPassword';  
赋权  
 \#> GRANT ALL PRIVILEGES ON \*.\* TO 'root'@'%' IDENTIFIED BY 'YourPassword' WITH GRANT OPTION;

刷新权限表【没啥屁用】

flush privileges;

测试连接，搞定！
