38 .. todo:: consider whether a central MySQL service should be setup
39
40 Many containers contain their own instance of MySQL. It might be a better
41 idea to centralize the MySQL setups in a single container.
42
43 .. todo:: consider whether a central PostgreSQL service should be setup
44
45 .. todo::
46
47 setup a central syslog service and install syslog clients in each container
48
49 .. _setup_apt_checking:
50
51 .. topic:: Setup package update monitoring for a new container
52
53 For Icinga to be able to check the update status of packages on you server
54 you need to install NRPE, a helper service. Install the necessary packages::
55
56 sudo aptitude install nagios-plugins-basic nagios-nrpe-server
57
58 Put :doc:`systems/monitor` on the list of allowed hosts to access the NRPE
59 service by adding the following line to :file:`/etc/nagios/nrpe_local.cfg`::
60
61 allowed_hosts=172.16.2.18
62
63 Tell the NRPE service that there is such a thing as the check_apt command by
64 creating the file :file:`/etc/nagios/nrpe.d/apt.cfg` with the following
65 contents::
66
67 # 'check_apt' command definition
68 command[check_apt]=/usr/lib/nagios/plugins/check_apt
69
70 # 'check_apt_distupgrade' command definition
71 command[check_apt_distupgrade]=/usr/lib/nagios/plugins/check_apt -d
72
73 Restart the NRPE service::
74
75 sudo service nagios-nrpe-server restart
76
77 Check that everything went well by going to https://monitor.cacert.org/,
78 going to the APT service on the host and clicking :guilabel:`"Re-schedule
79 the next check of this service"`. Make sure that :guilabel:`"Force Check"`
80 is checked and click :guilabel:`"Commit"`. Now you should see a page with a
81 green background. If not something went wrong, please contact the
82 :doc:`systems/monitor` administrators with the details.
83
84 That's it, now the package update status should be properly displayed in
85 Icinga.
86
87 .. todo:: think about replacing nrpe with Icinga2 satellites

89 Checklist
90 =========
91
92 .. index::
93 single: etckeeper
94 single: nrpe
95
96 * All containers should be monitored by :doc:`systems/monitor` and should
97 therefore have :program:`nagios-nrpe-server` installed
98 * All containers should use :program:`etckeeper` to put their local setup into
99 version control. All local setup should use :file:`/etc` to make sure it is
100 handled by :program:`etckeeper`
101 * All infrastructure systems must send their mail via :doc:`systems/emailout`
102 * All infrastructure systems should have an system-admin@cacert.org alias to
103 reach their admins
104 * The installation of :index:`systemd-sysv` in containers can be blocked by
105 putting the following lines in :file:`/etc/apt/preferences.d/systemd-sysv`::
106
107 Package: systemd-sysv
108 Pin: release a=stable
109 Pin-Priority: -1
110
111 .. todo:: document how to setup the system-admin alias on the email system
