此文参考我前面的文章《在CentOS上用yum方式安装MySQL8过程记录》之前比较曲折现在再安装一台mysql。
因为之前很多坑已经走过加上这台Linux之前没安装过MYSQL所以整个过程算是非常顺利。
安装环境centos7
mysql版本8.0.35
过程中使用过的命令
#查看CentOS版本
[root@localhost ~]# cat /etc/centos-release
#查看是否安装了其它版本的mysql
[root@localhost ~]# rpm -qa | grep mysql
#安装MYSQL8的yum源
[root@localhost ~]# yum localinstall https://repo.mysql.com//mysql80-community-release-el7-11.noarch.rpm
#列出已启用的软件包仓库
[root@localhost ~]# yum repolist enabled
#过滤出包含 “mysql.-community.” 关键字的软件包仓库。
[root@localhost ~]# yum repolist enabled | grep "mysql.*-community.*"
[root@localhost ~]# yum repolist all | grep mysql
[root@localhost ~]# yum repolist all | grep "启用"
#安装Mysql
[root@localhost ~]# yum install mysql-community-server
#启动mysqld
[root@localhost ~]# systemctl start mysqld
#查看mysqld状态
[root@localhost ~]# systemctl status mysqld
#获取临时密码
[root@localhost ~]# grep 'temporary password' /var/log/mysqld.log
#登录mysql
[root@localhost ~]# mysql -u root -p
mysql> use mysql;
#允许所有主机访问
mysql> update user set host = '%' where user = 'root';
mysql> FLUSH PRIVILEGES;
#修改密码和密码规则
mysql> alter user root@'%' identified with mysql_native_password by 'New*Password5';
mysql> FLUSH PRIVILEGES;
#查看密码
mysql> select Host,User,Plugin from mysql.user;
#防火墙放开端口
[root@localhost ~]# firewall-cmd --zone=public --add-port=3306/tcp --permanent
[root@localhost ~]# firewall-cmd --reload
真实操作记录
为方便理解以下为完整过程
[root@localhost ~]# cat /etc/centos-release
CentOS Linux release 7.9.2009 (Core)
[root@localhost ~]# rpm -qa | grep mysql
[root@localhost ~]#
[root@localhost ~]# yum localinstall https://repo.mysql.com//mysql80-community-release-el7-11.noarch.rpm
