4. 1. Turn off Ubuntu firewall UFW disable
2. Uninstall iptables apt get remove iptables
1. Use iptables - F to turn off the firewall, but before using this command, please remember to use iptables
- L to check the default target of all chains in your system. Iptables
- f only clears all rules, Just don't really turn off iptables. Imagine that if the default target of your chain is drop, originally you have rules to allow some specific ports,
but once you apply iptables - L and clear all the rules, the default target will block any access, Of course, you are included in the remote SSH management server.
so my recommended command to close the firewall is
iptables - P input accept
iptables - P forward accept
iptables - P output accept
iptables - f
in short, when you want to make any changes on your server, In addition, to make good use of iptables, it is necessary to understand the operation principle of
iptables and know how to handle iptables for each packet. Only in this way can you write rules accurately and avoid unnecessary trouble

If it's a Windows host, I suggest you install the website management assistant, which will be installed automatically after the selection in the environment detection, and the network search and download. If it is a Linux host, install WDCP. After the installation, it integrates MySQL and has a web management panel, which is very convenient to use.
