The installation is pretty straight forward. You can see the instructions via this link: http://centos-webpanel.com/cwp-installation or see the bellow:
CentOS 7: Installer for CentOS 7
If the download link doesn’t work then you can use the following:
CentOS 6: http://dl1.centos-webpanel.com/files/cwp2-latest
CentOS 7: http://dl1.centos-webpanel.com/files/cwp-el7-latest
Reboot your server so that all updates can take effect and CWP gets started.
OPTIONAL: INSTALLER ARGUMENTS
Available long name arguments
–restart yes (for automatic restart after successfull install)
–phpfpm [5.3|5.4|5.5|5.6|7.0|7.1|7.2|7.3] (you can use only one)
–softaculous yes (install softaculous – script installer)
Available short name arguments
-r yes (for automatic restart after successfull install)
-p [5.3|5.4|5.5|5.6|7.0|7.1|7.2|7.3] (you can use only one)
-s yes (install softaculous – script installer)
Example for centos 7 (you can combine short and long name arguments)
sh cwp-el7-latest -r yes --phpfpm 5.6 --softaculous yes
Any of this additionals can be also installed later from cwp gui.
Once CWP is installed you can tweak the sever security using CSF. Additionally you can disable the password login authentication for ssh and allow login only with ssh keys as well.
Hope this helps.
