CentOS 8.x Control Web panel Initial configuration

Home > CentOS > CentOS 8.x > CentOS 8.x email servers > CentOS 8.x Control Web panel > Initial configuration

Once installed initial configuration of CWP can be done as follows:

1. After Web login on https://<server-fqdn-or-ip>:2031/, click "Set Root Email" and update "Admin Email"

   Ideally also select "Forward server system emails" checkbox

2. If you are planning to host emails then
   1. Configure RDNS entries as per https://www.linode.com/docs/guides/configure-your-linode-for-reverse-dns/
   2. Open support ticket and request for email sending limitations removal. https://cloud.linode.com/support/tickets?type=closed&drawerOpen=true
3. In CWP go to "Server Settings" -> "Change Date & Time"

   Select correct timezone

   Click on "Apply this date and time below" against Your browser date & time

   Click "Change Date & Time"

4. Click on "/usr/local/php/php.ini" and the other php71/php.ini link
   1. In both files search for date.timezone setting and set it to

      date.timezone = "Asia/Kolkata"

   2. Save file
5. Go to PHP Settings -> PHP Version switcher. Select latest version. ("8.1.3" at time of this writing). Validate options esp. pgsql support and click "Save and build"

   We should get path to monitor progress such as "tail -f /var/log/php-rebuild.log". SSH to server and use the same to monitor installation progress.

   Monitoring the full progress would slow down the installation. Ideally have a look at log for a short while. Ctlr+c. Then open again.

6. Go to PHP Settings -> PHP Info and you should see selected version
7. Go to CWP Settings -> Back configuration. Unselect "Enable backup" and click "Save changes"
8. Go to Dashboard -> Mail services. Start all mail related services
9. Go to Dashboard -> Firewall. Click on "Enable firewall"
10. Create 2GB swap file using CentOS 7.x adding swap space using file
11. Also configure Storing date / time along with commands in history
12. Change SSH port as follows.
    1. Go to Dashboard and click link which takes to edit '/etc/ssh/sshd_config file
    2. Under #port 22 add line such as

       Port 36548

       Use other port based on your choice instead of 36548 given as example here

    3. Restart ssh service by going to Dashboard and clicking restart against SSH service.
13. Configure backup for server using rsnapshot and test one full backup. Take backup of at least /etc, /backup, /root, /home and /var

    backup          root@<server-ip-or-fqdn>:/etc/     <server-ip-or-fqdn>/       +ssh_args=-p 36548
    backup          root@<server-ip-or-fqdn>:/backup/  <server-ip-or-fqdn>/       +ssh_args=-p 36548
    backup          root@<server-ip-or-fqdn>:/home/    <server-ip-or-fqdn>/       +ssh_args=-p 36548
    backup          root@<server-ip-or-fqdn>:/root/    <server-ip-or-fqdn>/       +ssh_args=-p 36548
    backup          root@<server-ip-or-fqdn>:/var/     <server-ip-or-fqdn>/       +ssh_args=-p 36548

    The backup port mentioned in ssh_args should match the port on which SSH service is listening.

14. yum -y install logwatch
15. Edit root alias in /etc/aliases file and run

    newaliases

16. Test whether logwatch email is getting send properly or not by running

    /etc/cron.daily/0logwatch
