$ sudo /usr/local/lsws/bin/lswsctrl start
Access Web Server
By default, OpenLiteSpeed web server will be available on HTTP Port 8088 while the administrative WebAdmin console will be available on Port 7080. If you have firewall firewalld enabled, you need to open the respective ports for access.
Configure Firewall for Port Access
Add the firewall rules
$ sudo firewall-cmd --permanent --zone=trusted --add-service=http $ sudo firewall-cmd --permanent --zone=trusted --add-service=https $ sudo firewall-cmd --permanent --zone=public --add-port=8088/tcp $ sudo firewall-cmd --permanent --zone=public --add-port=7080/tcp
Reload firewalld to effect the changes
$ sudo firewall-cmd --reload
To confirm that the ports have been opened on the firewall, list everything added or enabled on the zone.
[linuxuser@centos7-litespeed ~]$ sudo firewall-cmd --list-all public (active) target: ACCEPT icmp-block-inversion: no interfaces: eth0 sources: services: http https ports: 7080/tcp 8088/tcp protocols: masquerade: no forward-ports: source-ports: icmp-blocks: rich rules:
Once the firewall has given access to those two ports, then you can access the web server.
In our case, it’s http://126.96.36.199:8088/ as shown belowFor the Webadmin Console
In our case it’s https://188.8.131.52:7080/ as shown belowAt first, you’ll get “Your connection is not secure” error since the browser does not recognize the site’s ssl certificate as it was automatically generated and self-signed by the Linux server during the web server installation.
Ignore that error and Click Advanced, then Click Add Exception as shown below:
“Add Security Exception” Tab pops up. Click Confirm Security Exception
Finally, the login page appears as shown below:
