1,本地链接服务器链接不上
Connection to project_name@ip failed. [08S01] Communications link failure. The last packet sent successfully to the server was 0 milliseconds ago. The driver has not received any packets from the server
这是因为mysql里面的配置没有配置你本机
1,找到mysql文件夹,然后找到内部的mysqld.conf文件
2,修改里面的bind-address,修改成你的ip或者是0.0.0.0(任何ip都允许)
cd /etc/mysql/mysqld.conf.d
vim mysqld.conf
修改bind-address,并把之前屏蔽掉
bind-address = 0.0.0.0
