问题描述

mysql看起来在公网提供服务

$ netstat -tulpn | grep mysqld
tcp        0      0 127.0.0.1:3306          0.0.0.0:*               LISTEN      4381/mysqld

telnet 127.0.0.1 3306可以通

但是telnet 公网ip 3306 报connection refused

解决办法

修改bind-address

vi /etc/mysql/mysql.conf.d/mysqld.cnf

将bind-address改为0.0.0.0

重启mysql

systemctl restart mysql

    Hi,

    I was looking at your website and noticed something interesting.

    Most businesses are losing potential customers because they are not actively managing their online reviews.

    Reviews can significantly increase trust and conversions when handled properly.

    I recently found a tool that automatically collects, manages, and improves online reviews for businesses.

    You can see how it works here:

    It’s surprisingly simple and can make a big difference in attracting new customers.

    Hi,

    I just visited liushiming.cn and wondered if you’d ever thought about having an engaging video to explain what you do?

    Our videos cost just $195 (USD) for a 30 second video ($239 for 60 seconds) and include a full script, voice-over and video.

    I can show you some previous videos we’ve done if you want me to send some over. Let me know if you’re interested in seeing samples of our previous work.

    Regards,
    Joanna

    Hey,

    I used to feel tired and low on energy after eating, and I thought it was normal.

    But then I found out it could be related to blood sugar balance.

    I came across a simple explanation and something that helped me feel more stable during the day.

    So I shared it here if you want to check it out:
