  小编这次要给大家分享的是CentOS7版本如何安装Mysql8.0.20版本数据库,文章内容丰富,感兴趣的小伙伴可以来了解一下,希望大家阅读完这篇文章之后能够有所收获。
 
  官网下载有时速度比较慢,直接点击链接也可以下载:mysql 8.0.20
 
  官网下载8.0.20Mysql包(bundle版本)
 
  1.创建mysql文件夹:
 
  [root@localhost ~]# mkdir /usr/local/mysql
  [root@localhost ~]# cd /usr/local/mysql/
  将下载的mysql包放在创建的MySQL文件夹内:
 
  [root@localhost mysql]# ll
  总用量 815000
  -rw-r--r--. 1 root root 834560000 5月 13 10:44 mysql-8.0.20-1.el7.x86_64.rpm-bundle.tar
  mysql的安装版MD5码查看是否和官网上的相对应:
 
  [root@localhost mysql]# md5sum mysql-8.0.20-1.el7.x86_64.rpm-bundle.tar
  c8d062c1f74d9aab7dbdd5300b202b6e mysql-8.0.20-1.el7.x86_64.rpm-bundle.tar
  将mysql的包解压得到几个内安装包:
 
  [root@localhost mysql]# tar -xvf mysql-8.0.20-1.el7.x86_64.rpm-bundle.tar
  mysql-community-libs-8.0.20-1.el7.x86_64.rpm

  [root@localhost mysql]# systemctl start mysqld.service
  [root@localhost mysql]# systemctl status mysqld.service

  查看数据库初始的密码:
 
  [root@localhost mysql]# cat /var/log/mysqld.log | grep password

  使用初始密码登陆数据库:后更改密码:
 
  [root@localhost mysql]# mysql -uroot -p
  Enter password:
