Let's install a brand new Centos 7 Server along with needed database, web servers and Wordpress. INSTALL SSL ON HAPROXY CENTOS 7 OR UBUNTU 14.04 FOR MOODLE; INSTALL SEPARATE MEMCACHE SERVER (SESSION) FOR MOODLE ON CENTOS 7. Firewall Settings $ sudo firewall-cmd --permanent --add-service=http. Transparent Proxy Issues w/ HAProxy Centos 7. Having issues following steps to transparent proxy outlined here: Believe to successfully done all the steps but having issues layer 4 TLS requests. The goal being in TCP mode load balance http requests on port 80 and port 443 onto webserver, where webserver terminates TLS connections.

Once you’ve from SSH on your server, the next step is to install a basic firewall to filter out nasty incoming connections. This includes a “Login Failure Daemon” to watch out for repeated login errors and block out the IP addresses for a certain time. Configuring a CentOS firewall on a fresh installation is easy. You just need to have a little bit of background so you know what you’re doing.
IPTables and CSF Though there are many firewall management tools for Linux, they all rely on a more fundamental service called “iptables”. By itself, Iptables can be rather complicated and difficult to use. So we’re going to use a popular package called CSF (ConfigServer Security & Firewall) to manage Iptables on our behalf.
It makes tasks such as opening a port, and blocking an IP address much easier than having to do it directly through Iptables. Unlike Iptables, CSF can be easily configured through a single configuration file that already has several helpful defaults built into it. The syntax is easy to figure out and you can interact with CSF through the command line as well. In addition, the CSF package also has a login daemon that protects us against brute force attacks. So let’s start with installing CSF on a fresh CentOS server. Step 1: Check if Perl is Installed CSF relies on the Perl module, which usually comes installed with most Linux distros. Check and see whether or not it’s installed using the following command.
Vi /etc/csf/csf.conf Once the file /etc/csf/csf.conf is opened, scroll down to the line called TESTING = “1” and change “1” to “0” as shown here. This disables test mode and allows the login daemon to work. Also, if you log in via SSH through a port other than 22, scroll down till you find the line starting with “TCPIN”, and add your port to the end of the comma separated list of numbers: Step 5: Basic CSF Configuration Before we enable the firewall, here are some configuration settings you can set right away in /etc/csf/csf.conf.
