Sorry - sent email to Mark by accident:
Systemd? Yes
[root at mythmaster ~]# pstree -p | grep system
systemd(1)-+-ModemManager(578)-+-{ModemManager}(604)
|-systemd-journal(366)
|-systemd-logind(584)
|-systemd-udevd(397)
Not sure how to find out if BE is running as root. If you mean under the
mythbackend.service file - ( vi /usr/lib/systemd/system/mythbackend.service)
-- then I tried both here:
# systemd changes execution from the calling user (possibly root) to this
user
# if you have permissions problems or obscure errors try logging in as
mythtv
User=mythtv
#User=root
I had commented out "user=mythtv" and put root instead - but that didn't
change anything.
What's in it - what was default i believe:
[Unit]
Description=MythTV backend service
After=network-online.target mariadb.service mysqld.service time-sync.target
# Uncomment the following line if you will be using the mythweb plugin on
the
# same system as mythbackend.
#Wants=httpd.service
[Service]
# Type=simple is recommended. If using Type=forking you will need to
specify a
# pidfile so systemd knows how to find the forked process PID, otherwise it
# presumes that the process being started will be the remaining process.
#Type=forking
Type=simple
Environment=MYTHCONFDIR=/etc/mythtv
# systemd changes execution from the calling user (possibly root) to this
user
# if you have permissions problems or obscure errors try logging in as
mythtv
User=mythtv
#User=root
# Uncomment one of the following...
# Use sysloging rather than separate logging:
#ExecStart=/usr/bin/mythbackend --syslog local7
# If Type=forking is set you must specify the --daemon and --pidfile
options:
#ExecStart=/usr/bin/mythbackend --daemon --logpath /var/log/mythtv
--loglevel crit --pidfile /run/mythbackend.pid
# Default setting for Type=simple.
ExecStart=/usr/bin/mythbackend --logpath /var/log/mythtv
[Install]
WantedBy=multi-user.target
--------------------------------
Also noticed that since the path is /etc/mythtv (not /root/.mythtv)
the permissions are:
[root at mythmaster ~]# ls -ahl /etc/mythtv
total 36K
drwxr-xr-x. 6 mythtv mythtv 4.0K Aug 1 22:44 .
drwxr-xr-x. 140 root root 12K Aug 1 22:23 ..
drwxr-xr-x. 2 mythtv mythtv 4.0K Aug 1 20:00 3rdParty
drwxr-xr-x. 2 mythtv mythtv 4.0K Aug 1 20:00 channels
-rw-r--r--. 1 mythtv mythtv 513 Aug 1 22:44 config.xml
-rw-r--r--. 1 root root 0 Aug 1 22:43 config.xml.old
drwxr-xr-x. 2 mythtv mythtv 4.0K Aug 1 20:00 themes
drwxr-xr-x. 3 mythtv mythtv 4.0K Aug 1 20:00 tmp
Wondering if there is a need to change either the path or permissions?
