先去下载 https://dev.mysql.com/downloads/mysql/
然后上传到Linux
进入存放目录，解压到指定目录【我这里是/soft/mysql8】
[root@localhost ~]# cd /soft/ [root@localhost soft]# mkdir mysql8 [root@localhost soft]# tar -xvf mysql-8.0.16-2.el7.x86_64.rpm-bundle.tar -C mysql8/ mysql-community-libs-8.0.16-2.el7.x86_64.rpm mysql-community-embedded-compat-8.0.16-2.el7.x86_64.rpm mysql-community-devel-8.0.16-2.el7.x86_64.rpm mysql-community-server-8.0.16-2.el7.x86_64.rpm mysql-community-libs-compat-8.0.16-2.el7.x86_64.rpm mysql-community-client-8.0.16-2.el7.x86_64.rpm mysql-community-common-8.0.16-2.el7.x86_64.rpm mysql-community-test-8.0.16-2.el7.x86_64.rpm
进入解压后的目录，安装
[root@localhost soft]# cd mysql8/
[root@localhost mysql8]# yum install mysql-community-{server,client,common,libs}-*

到此就安装结束，下面开启防火墙端口3306并启动。开启防火墙端口是希望外界可以访问。
[root@localhost mysql8]# firewall-cmd --zone=public --add-port=3306/tcp --permanent
success
[root@localhost mysql8]# systemctl restart firewalld
[root@localhost mysql8]# systemctl start mysqld
[root@localhost mysql8]# systemctl status mysqld

下面因为第一次启动，需要修改密码。
[root@localhost mysql8]# cat /var/log/mysqld.log | grep password 2019-05-23T21:20:25.393815Z 5 [Note] [MY-010454] [Server] A temporary password is generated for root@localhost: U3ZlzC>KAAc< [root@localhost mysql8]# mysql -u root -p Enter password: Welcome to the MySQL monitor.

到此安装以及初始化完毕，你可以在此执行一些SQL语句。
你要创建一个新用户并授权。
mysql> CREATE USER ‘tom‘@‘%‘ IDENTIFIED BY ‘Abc123-S‘; Query OK, 0 rows affected (0.02 sec) mysql> GRANT ALL ON *.* TO ‘tom‘@‘%‘; Query OK, 0 rows affected (0.02 sec)
连接的时候会出现
这是因为不支持当前的加密协议。MySQL8 创建用户默认使用caching_sha2_password，所以我们可以更改为MySQL5.7的mysql_native_password。
mysql> ALTER USER ‘tom‘@‘%‘ IDENTIFIED WITH mysql_native_password BY ‘Abc123-S‘; Query OK, 0 rows affected (0.00 sec)
