Step 1: Install repository

CentOS 7:

yum install epel-release
rpm -ivh http://rpms.litespeedtech.com/centos/litespeed-repo-1.1-1.el7.noarch.rpm 

CentOS 6:

yum install epel-release
rpm -ivh http://rpms.litespeedtech.com/centos/litespeed-repo-1.1-1.el6.noarch.rpm

Step 2: Ensure you have removed any other HTTP web server (apache,nginx)

You can check this by executing this command:

rpm -qa | grep 'apache\|nginx'

Install latest/recent version of OpenLiteSpeed from yum:

yum install openlitespeed

Then we need to symlink the lib folder

ln -s /usr/local/lsws/lsphp56/lib64 /usr/local/lsws/lsphp56/lib

Step 4: Firewall configurations

If you have firewall installed ensure this ports are open:

  • 80
  • 443
  • 8080
  • 7080

For iptables use this commands to open the ports:

iptables -I INPUT -p tcp --dport 80 -j ACCEPT
iptables -I INPUT -p tcp --dport 443 -j ACCEPT
iptables -I INPUT -p tcp --dport 8080 -j ACCEPT
iptables -I INPUT -p tcp --dport 7080 -j ACCEPT

Step 5: Start OpenLiteSpeed and login to dashboard

To start OpenLiteSpeed:

systemctl start lsws

To stop and restart:

systemctl stop lsws
systemctl restart lsws

Now we need to reset the OpenLiteSpeed admin password :

cd /usr/local/lsws/admin/misc
./admpass.sh

When prompting for username leave it blank eg.:

[[email protected] ~]# cd /usr/local/lsws/admin/misc
[[email protected] misc]# ./admpass.sh

Please specify the user name of administrator.
This is the user name required to login the administration Web interface.

User name [admin]:

Please specify the administrator's password.
This is the password required to login the administration Web interface.

Password: 
Retype password: 
Administrator's username/password is updated successfully!

Step 6: Login to OpenLiteSpeed admin panel

https://10.135.87.168:7080

replace 10.135.87.168 with your server ip.

Step 7: Configure port 80 (http) and 443 (https)

The default http port for OpenLiteSpeed is 8080, it’s used to receive the client requests. In this step, we will change the port to 80 from the OpenLiteSpeed management GUI.

On the left side, go to the “Listeners” section to see the listeners configuration. You will see the default listener with port 8080. Click “view” zoom icon to see details configuration. Now click “Edit”.

IP Address: ANY
Port 80

Change the port to 80 and save the configuration.

For SSL 443 follow this official documentation: https://openlitespeed.org/mediawiki/index.php/Help:SSL_Setup
To apply changes, please perform a graceful restart.
