This article provides instructions on how to check if the Server Name Indication (SNI) extension is installed on your server.
To check if the Apache web server with SNI support is installed, use the Autoinstaller utility.
Check if "Apache web server with SNI support" is included in the list of installed components: # /usr/local/psa/admin/sbin/autoinstaller --select-release-current --show-components |grep SNI apache-sni [up2date] - Apache web server with SNI support
You can check it with this package:
# rpm -qa |grep sni apache-sni-configurator-2.2.22-12051419
Or this command:
[root@test]# cat /etc/psa/psa.conf | grep SNI # SNI SNI_SUPPORT true
NOTE: Some operating Systems support SNI by default, so it will not be avaiable in Plesk autoinstaller for installation. Operating Systems that support SNI by default:
Redhat enterprise Linux 6.x and later Fedora 10 and later Centos 6.x SNI Debian 6.x and later Ubuntu 10.04 and later
