SVN open firewall port introduction, svn firewall port
Preface

Due to the previous laziness, the firewall was shut down after the server was installed with svn. Recently, the server was told to show signs of virus, so the Firewall should be enabled, however, opening the firewall will lead to svn access failure, so now there is a new requirement to open the svn service port.

Disable the firewalld Firewall service provided by the Virtual Machine

systemctl stop firewalld

Disable firewall auto-start

systemctl disabled firewalld

Install iptables-services

yum install -y iptables-services

Start the iptables service

systemctl start iptables

Set iptables to start automatically

systemctl enable iptables

Open/etc/sysconfig/iptables and enter the following content. Note that this sentence should be placed on the top of the last sentence, otherwise it will not take effect.

-A INPUT -m state --state NEW -m tcp -p tcp --dport 3690 -j ACCEPT-A OUTPUT -m state --state NEW -m tcp -p tcp --dport 3690 -j ACCEPT

Restart the firewall to make the modification take effect.

service iptables restart

The VM firewall port 3690 is enabled. You can also run the following command to enable it:

iptables -I INPUT -p tcp --dport 8080 -j ACCEPTiptables -I OUTPUT -p tcp --dport 8080 -j ACCEPTservice iptables save

It takes effect after the service is restarted.

Summary

In fact, the process is not difficult, but we are a little lazy when we are doing it. When the problem arises, we will return to solve it again. Therefore, we will not be able to develop it in the first place, do a good job.
