Scenario:
Apache Port Change:
We all know that the default Port number of Apache is 80. For more security purpose we will be forced for Apache port change, Please see below mentioned steps inorder to change the port number.Assume you need to change the port number of httpd from 80 to 8080 and for https from 443 to 1023
Search the httpd configuration file
#vi /usr/local/apache/conf/httpd.conf
For changing httpd port
Find this line- Listen 80 in the configuration file.
Listen 0.0.0.0:80
Change it to
Listen 0.0.0.0:8080
Now save the edited file.
For changing https port
Find this line- Listen 443 in the configuration file.
Listen 0.0.0.0:443
Replace the following line by Listen 0.0.0.0:1023
Listen 0.0.0.0:1023
Now save the edited file.
Finally restart the Apache service.
#/etc/init.d/httpd restart
he Port has been changed successfully.
Now you need to open those ports in firewall. Inorder to open the ports follow below mentioned steps.
# Allow incoming TCP ports
TCP_IN = “20,21,22,25,53,8080,110,143,1023,465,587,993,995,2077,2078,2082,2083,2086,2087,2095,2096,23220,287,3306″
# Allow outgoing TCP ports
TCP_OUT = “20,21,22,25,37,43,53,8080,110,113,1023,587,873,2087,2089,2703,3306″
And Restart the CSF
#/etc/init.d/csf restart
Follow the steps to check the modifications are working correctly or not.
For example consider the IP 67.228.194.218
#telnet 67.228.194.218 8080
Trying 67.228.194.218…
Connected to 67.228.194.218.
Escape character is ‘^]’.
^]
telnet> q
Connection closed.#telnet 67.228.194.218 1023
Trying 67.228.194.218…
Connected to 67.228.194.218.
Escape character is ‘^]’.
^]
telnet> q
Connection closed.
If the telnet is connected to the server, we can confirm that the port has been changed successfully.
