This section describes how to configure the repo server in order to install Session Monitor.

1. Copy the RPMs to the repo server in a temporary directory, such as /tmp/ocsm/.
2. Install the following RPMs in this order:
   1. rpm -ivh vsftpd-3.0.2-25.el7.x86_64.rpm
   2. rpm -ivh deltarpm-3.6-3.el7.x86_64.rpm
   3. rpm -ivh python-deltarpm-3.6-3.el7.x86_64.rpm
   4. rpm -ivh createrepo-0.9.9-28.el7.noarch.rpm
3. Move the /tmp/ocsm/ directory to /var/ftp/pub/ by running the following command:

   mv /tmp/ocsm/  /var/ftp/pub/

   OCSM, MySQL, and other dependency RPMs are now located in /var/ftp/pub/ocsm/.
4. Create the repo by running the following command:

   createrepo  /var/ftp/pub/ocsm/

5. Add a comment in front of the root line of /eyc/vsftpd/ftpusers and /etc/vsftpd/user_list using "#" to say the following:

   [root@test vsftpd]# cat /etc/vsftpd/ftpusers
   # Users that are not allowed to login via ftp
   #root
   bin
   daemon
   adm
   lp
   sync
   shutdown
   halt
   mail
   news
   uucp
   operator
   games
   nobody
   

   [root@test vsftpd]# cat /etc/vsftpd/user_list
   # vsftpd userlist
   # If userlist_deny=NO, only allow users in this file
   # If userlist_deny=YES (default), never allow users in this file, and
   # do not even prompt for a password.
   # Note that the default vsftpd pam config also checks /etc/vsftpd/ftpusers
   # for users that are denied.
   #root
   bin
   daemon
   adm
   lp
   sync
   shutdown
   halt
   mail
   news
   uucp
   operator
   games
   nobody
   

6. Start the vsftp service by running the following commands:

   systemctl start vsftpd

   systemctl enable vsftpd

7. Check the status of vsftp service by running the following command:

   systemctl status vsftpd

   The status of the service should be active (running).
8. Disable the firewall by running the following commands:

   systemctl stop firewalld

   systemctl disable firewalld
