Hello everyone
I have some remarks about starting FRED components automatically after boot in Ubuntu
16.04 LTS
xenial. If anyone has some input, please share.
First, I suspect that upstart job definitions are obsolete and should removed. I mean the
files:
/etc/init/fred-adifd.conf
/etc/init/fred-logd.conf
/etc/init/fred-msgd.conf
/etc/init/fred-pifd.conf
/etc/init/fred-rifd.conf
Next, right after installation the services of FRED were not enabled, hence:
# cd /lib/systemd/system
# systemctl enable fred*
This is not enough, since fred-pyfred failed because it was started too early (before
omniorb name
server), therefore I modified unit definition of fred-pyfred in
/lib/systemd/system/fred-pyfred.service
so now it looks like this:
[Unit]
Description=fred-pyfred
After=omniorb4-nameserver.service
#ConditionPathExists=!/etc/ssh/sshd_not_to_be_run
Requires=omniorb4-nameserver.service
[Service]
User=fred
WorkingDirectory=/
StandardOutput=null
StandardError=null
ExecStart=/usr/sbin/fred-pyfred -d
KillMode=process
Restart=on-failure
[Install]
WantedBy=multi-user.target
and generates the following result:
# systemd-analyze critical-chain fred-pyfred.service
The time after the unit is active or started is printed after the "@"
character.
The time the unit takes to start is printed after the "+" character.
fred-pyfred.service @6.814s
└─omniorb4-nameserver.service @6.774s +23ms
└─network-online.target @6.764s
└─NetworkManager-wait-online.service @927ms +5.837s
└─NetworkManager.service @665ms +185ms
└─dbus.service @639ms
└─basic.target @639ms
└─sockets.target @639ms
└─snapd.socket @637ms +1ms
└─sysinit.target @634ms
└─swap.target @634ms
└─dev-disk-by\x2duuid-d8b40e4d\x2d4e62\x2d4436\x2db09b\x2d8cfc2a2d8a1d.swap
@629ms +3ms
└─dev-disk-by\x2duuid-d8b40e4d\x2d4e62\x2d4436\x2db09b\x2d8cfc2a2d8a1d.device
@623ms
(of course your delays will vary).
To check if FRED services are running, one may use
# systemctl status fred*
Maybe this page could get an update? https://fred.nic.cz/page/2906/installation-ubuntu/
