一.场景
环境:centos7 mysql源 http://repo.mysql.com/mysql57-community-release-el7-8.noarch.rpm
1.Mysql安装好后 linux服务器端操作正常,但使用Navicat链接报错
Can't connect to MYSQL server on ''(10060)
二.问题排查
1.开放端口
[root@localhost ~]# firewall-cmd --permanent --zone=public --add-port=3306/tcp
[root@localhost ~]# firewall-cmd --reload
2.再链接正常
