+
+If you are using CentOS7, starting from ePortal version 2.4-2, it's necessary to install the `centos-release-scl` package. 
+You can do so with the following command:
+
+```
+yum install centos-release-scl
+```
+
+For RHEL7 users, you'll need to enable the necessary repositories to ensure access to the required packages. Use the subscription-manager utility with the following commands:
+
+```
+subscription-manager repos --enable rhel-7-server-optional-rpms
+subscription-manager repos --enable rhel-server-rhscl-7-rpms
+```
