Install MythTV Frontend v27.5 on Centos v7.1 (scrpms)
Old notes from a previous install from 2016.
These are notes on installing MythTV frontend on a low end old AMD frontend, with a nVidia graphics card, a Microsoft remote and NFS for video. The MythTV backend and MySQL/MariaDB database server run on independent virtual machines (not covered by these notes).
This install was done while ATrpms was down (with the possibility that it may not return). I had a local copy of the ATrpms mirror I used for dependencies.
Steps
- Install base machine (CentOS 7)
- Install nVidia graphics driver
- Install MythTV frontend
- Add a mythtv user that auto-logins in and runs mythtv frontend
- Disable screen savers
- Add an NFS share with videos
- Configure sound via HDMI
Install the base operating system with gnome and setup network connectivity.
Set the hostname in '/etc/hostname':
cobalt.lucidsolutions.co.nz
Disable network manager on the main network interface:

Lock down ssh.
Repositories
Setup the following RPM repositories:
- scrpms (mythtv)
- atrpms (dead)
- epel (dependency)
- elrepo (nVidia driver)
# rpm -Uvh http://mirror.xnet.co.nz/pub/epel/7/x86_64/e/epel-release-7-5.noarch.rpm # rpm -Uvh http://dl.atrpms.net/all/atrpms-repo-7-7.el7.x86_64.rpm # yum install http://www.elrepo.org/elrepo-release-7.0-2.el7.elrepo.noarch.rpm
Create a local repo file for scrpms in '/etc/yum.repos.d/scrpms.repo':
[scrpms]
name=A CentOS Build of MythTV v0.27 by Stephen Collier
baseurl=http://scrpms.net/pub/RPMS/el7/$basearch/
ftp://167.160.167.42/pub/RPMS/el7/$basearch/
http://share.lucidsolutions.co.nz/scrpms/RPMS/el7/$basearch/
gpgkey=http://scrpms.net/pub/RPM-GPG-KEY.scrpms
enabled=1
gpgcheck=1
Note: At the time of writing ATRpms was down, so I used my local (private) mirror:
# rpm -Uvh http://mirror.lucidsolutions.co.nz/atrpms/el7/x86_64/stable/atrpms-repo-7-7.el7.x86_64.rpm
Install
yum install kmod-nvidia
yum remove xorg-x11-glamor
# yum install mythtv-frontend
Disable nouvea driver
Add a blacklist command to the linux command line in '/etc/default/grub':
GRUB_CMDLINE_LINUX="crashkernel=auto rhgb quiet rdblacklist=nouveau"
And regenerate the grub configuration:
# grub2-mkconfig -o /boot/grub2/grub.cfg
Frontend User
Add a user for the front-end.
# adduser mythtv # passwd mythtv
Automatic lauch
Auto login
Edit '/etc/gdm/custom.conf' to configure the mythtv user to automatically log in:
[daemon]
AutomaticLoginEnable=true
AutomaticLogin=mythtv
Auto start
Create a startup script that will lauch (and re-lauch if it crashes) the mythfrontend program as '/usr/local/bin/start-mythtvfrontend'. Tweak this up as required to display screen savers etc. Due to bug 12034 I have to display the http proxy settings otherwise recordings won't play.
#!/bin/bash # see https://code.mythtv.org/trac/ticket/12034 export http_proxy= export https_proxy= export ftp_proxy= export no_proxy= xset -dpms s off xsetroot -solid black while ( ! $( mythfrontend > /tmp/mythfrontend.log 2>&1 ) ) ; do echo "Restart in a few seconds" sleep 5s done
Create a gnome autostart desktop file '~mythtv/.config/autostart/mythtv-frontend.desktop':
[Desktop Entry] Type=Application Name=MythTV Frontend Exec=/usr/local/bin/start-mythtvfrontend Icon=mythfrontend.png Categories=X-Red-Hat-Extra;Application;AudioVideo;
Videos
Mount the collection of video using NFS. This is made available over a storage VLAN. Add a network sub-interface configuration file '/etc/sysconfig/network-scripts/ifcfg-enp3s0.200':
VLAN=yes DEVICE=enp3s0.200 TYPE=Ethernet ONBOOT=yes BOOTPROTO=none NM_CONTROLLED=no # IPv4 IPADDR=10.20.100.5 NETMASK=255.255.255.0 MTU=9000 # IPv6 IPV6ADDR=fd0c:898b:471c:0064::5/64 IPV6_MTU=9000
Create a directory for the NFS mount
# mkdir /mnt/mp4
Add an entry to '/etc/fstab':
10.20.100.2:/mnt/puddle/ds-video /mnt/mp4 nfs4 ro 0 0
Verify that the NFS mount is operational (mount -a)
Remote control
Add Linux device input support
# yum install v4l-utils lirc lirc-remotes iguanaIR libcecNote: '
iguanaIR' is an unexpressed library dependency.
/bin/cp /usr/share/lirc-remotes/devinput/lircd.conf.devinput /etc/lirc/lircd.conf systemctl enable lircd systemctl start lircd
Disable unused services
# for S in ModemManager cups firewalld bluetooth ; do systemctl stop $S ; systemctl stop $S ; done
