\"csfSecurity is one of the most\u00a0important things you need to\u00a0consider if you have an online business. The best security practices for keeping your server protected include an advanced firewall service. Today we will discuss and explain\u00a0how to install Config Server Firewall (CSF), which is one of the most advanced firewall services for a Linux VPS<\/a>. The installation process is,\u00a0as a matter of fact, very\u00a0simple and it is not time consuming at all, so if you are ready, we can begin.<\/p>\n

<\/p>\n

For today’s tutorial, we are using a CentOS VPS <\/a>,\u00a0but do not worry if you are using another Linux distribution on your VPS since it should work without any problems.<\/p>\n

The first thing you need to do is to update all your system software to the latest version available. For that purpose, you can carry out\u00a0the command:<\/p>\n

yum update<\/pre>\n
Once you execute this command, your system will be up to date and you\u00a0can commence\u00a0the installation of Config Server Firewall. Navigate to your \/root directory:<\/p>\n
cd \/root<\/pre>\n
Now, when you are in your \/root directory you can download the Config Server Firewall from the official web site. For that purpose you can use the following command:<\/p>\n
wget https:\/\/download.configserver.com\/csf.tgz<\/pre>\n
Next thing you need to do is to unpack the archive:<\/p>\n
tar -zxvf csf.tgz<\/pre>\n
Enter into the newly created directory on your Linux VPS:<\/p>\n
cd csf\/<\/pre>\n
And start the installation script:<\/p>\n
sh install.sh<\/pre>\n
After few seconds of time, the Config Server Firewall should be installed on your Linux VPS<\/a> and it should be ready to use.
\nAs many other services, Config Server Firewall can be started, stopped, or restarted using init scripts. For instance, to start your Config Server Firewall you can use the command:<\/p>\n
\/etc\/init.d\/csf start<\/pre>\n
If you like to stop your Config Server Firewall, you can execute the command:<\/p>\n
\/etc\/init.d\/csf stop<\/pre>\n
Or, in case\u00a0you like to restart your Config Server Firewall service you can run the command:<\/p>\n
\/etc\/init.d\/csf restart<\/pre>\n
Also, as many other Linux services, you can configure Config Server Firewall\u00a0to meet\u00a0your needs. The main configuration file is stored in your \/etc directory under \/csf.<\/p>\n
\/etc\/csf\/csf.conf<\/pre>\n
Finally, we will show you how to use Config Server Firewall. If you like to allow a specific\u00a0IP address to access your Linux VPS, you can use the command:<\/p>\n
csf -a IPADDRESS<\/pre>\n
Please do not forget to replace IPADDRESS with the actual IP address.
\nIn case\u00a0you like to block certain IP address, you can use the command:<\/p>\n
csf -d IPADDRESS<\/pre>\n
Again, do not forget to replace IPADDRESS with the actual IP address.
\nIn\u00a0the end, if you like to reload all the rules you can execute:<\/p>\n
csf -r<\/pre>\n
Of course you don\u2019t have to do any of this if you use one of our Linux VPS hosting services<\/a>, in which case you can simply ask our expert Linux admins to install Config Server Firewall for you. They are available 24\u00d77 and will take care of your request immediately.<\/p>\n
