零，报错日志 2002-Can't connect to server on'106.54.209.77'(1006x)

今天差点被这个报错给折磨疯掉

尝试一：对腾讯云服务器进行更改

尝试二：针对配置文件处理

step1

//确保注释 /etc/mysql/mysql.conf.d/mysqld.cnf 下# bind-address          = 127.0.0.1#  mysqlx-bind-address  = 127.0.0.1

step2 重新加载服务器配置文件

sudo systemctl daemon-reload

step3

sudo systemctl restart mysql

尝试三：开启MySQL的远程访问权限

USE mysql;
CREATE USER 'root'@'%' IDENTIFIED BY '密码';
GRANT ALL PRIVILEGES ON *.* TO 'root'@'%' WITH GRANT OPTION;
select user,host from user;

顺便对于vscode

顺便今天似乎vscode连接不上ubuntu，是因为乱处理上面的问题，给出如下方法

sudo ufw enable
#Command may disrupt existing ssh connections. Proceed with operation (y|n)? y
#Firewall is active and enabled on system startup
