[root@localhost ~]# ls mysql-5.7.28-1.el7.x86_64.rpm-bundle.tar
mysql-5.7.28-1.el7.x86_64.rpm-bundle.tar
[root@localhost ~]# mkdir mysql
[root@localhost ~]# [root@localhost ~]# tar -xf mysql-5.7.28-1.el7.x86_64.rpm-bundle.tar -C mysql
[root@localhost ~]# cd mysql
此处使用yum的本地安装 localinstall 但是建议使用网络yum 因为有以下两个包需要联网下载
(1/2): perl-Data-Dumper-2.145-3.el7.x86_64.rpm | 47 kB 00:00:00
(2/2): perl-JSON-2.59-2.el7.noarch.rpm | 96 kB 00:00:04
[root@localhost mysql]# yum -y localinstall *.rpm
3. 启动并设置密码
[root@localhost mysql]# systemctl start mysqld
[root@localhost mysql]# grep "temporary password" /var/log/mysqld.log
2019-12-26T13:39:18.805675Z 1 [Note] A temporary password is generated for root@localhost: aTb#ynPk?8Jj
aTb#ynPk?8Jj 是临时密码 可以用于首次登陆 如下
[root@localhost mysql]# mysql -uroot -p'aTb#ynPk?8Jj'
mysql: [Warning] Using a password on the command line interface can be insecure.
