1 # Upgrading Icinga 2 <a id="upgrading-icinga-2"></a>
3 Upgrading Icinga 2 is usually quite straightforward. Ordinarily the only manual steps involved
4 are scheme updates for the IDO database.
6 Specific version upgrades are described below. Please note that version
7 updates are incremental. An upgrade from v2.6 to v2.8 requires to
8 follow the instructions for v2.7 too.
10 ## Upgrading to v2.8.2 <a id="upgrading-to-2-8-2"></a>
12 With version 2.8.2 the location of settings formerly found in `/etc/icinga2/init.conf` has changed. They are now
13 located in the sysconfig, `/etc/sysconfig/icinga2` (RPM) or `/etc/default/icinga2` (DPKG) on most systems. The
14 `init.conf` file has been removed and its settings will be ignored. These changes are only relevant if you edited the
15 `init.conf`. Below is a table displaying the new names for the affected settings.
17 Old `init.conf` | New `sysconfig/icinga2`
18 ----------------|------------------------
19 RunAsUser | ICINGA2\_USER
20 RunAsGroup | ICINGA2\_GROUP
21 RLimitFiles | ICINGA2\_RLIMIT\_FILES
22 RLimitProcesses | ICINGA2\_RLIMIT\_PROCESSES
23 RLimitStack | ICINGA2\_RLIMIT\_STACK
26 ## Upgrading to v2.8 <a id="upgrading-to-2-8"></a>
28 ### DB IDO Schema Update to 2.8.0 <a id="upgrading-to-2-8-db-ido"></a>
30 There are additional indexes and schema fixes which require an update.
32 Please proceed here for [MySQL](16-upgrading-icinga-2.md#upgrading-mysql-db) or [PostgreSQL](16-upgrading-icinga-2.md#upgrading-postgresql-db).
36 > `2.8.1.sql` fixes a unique constraint problem with fresh 2.8.0 installations.
37 > You don't need this update if you are upgrading from an older version.
39 ### Changed Certificate Paths <a id="upgrading-to-2-8-certificate-paths"></a>
41 The default certificate path was changed from `/etc/icinga2/pki` to
42 `/var/lib/icinga2/certs`.
45 ---------------------------------------------------|---------------------------------------------------
46 `/etc/icinga2/pki/icinga2-client1.localdomain.crt` | `/var/lib/icinga2/certs/icinga2-client1.localdomain.crt`
47 `/etc/icinga2/pki/icinga2-client1.localdomain.key` | `/var/lib/icinga2/certs/icinga2-client1.localdomain.key`
48 `/etc/icinga2/pki/ca.crt` | `/var/lib/icinga2/certs/ca.crt`
50 This applies to Windows clients in the same way: `%ProgramData%\etc\icinga2\pki`
51 was moved to `%ProgramData%\var\lib\icinga2\certs`.
54 ----------------------------------------------------------------|----------------------------------------------------------------
55 `%ProgramData%\etc\icinga2\pki\icinga2-client1.localdomain.crt` | `%ProgramData%\var\lib\icinga2\certs\icinga2-client1.localdomain.crt`
56 `%ProgramData%\etc\icinga2\pki\icinga2-client1.localdomain.key` | `%ProgramData%\var\lib\icinga2\certs\icinga2-client1.localdomain.key`
57 `%ProgramData%\etc\icinga2\pki\ca.crt` | `%ProgramData%\var\lib\icinga2\certs\ca.crt`
62 > The default expected path for client certificates is `/var/lib/icinga2/certs/ + NodeName + {.crt,.key}`.
63 > The `NodeName` constant is usually the FQDN and certificate common name (CN). Check the [conventions](06-distributed-monitoring.md#distributed-monitoring-conventions)
64 > section inside the Distributed Monitoring chapter.
66 The [setup CLI commands](06-distributed-monitoring.md#distributed-monitoring-setup-master) and the
67 default [ApiListener configuration](06-distributed-monitoring.md#distributed-monitoring-apilistener)
68 have been adjusted to these paths too.
70 The [ApiListener](09-object-types.md#objecttype-apilistener) object attributes `cert_path`, `key_path`
71 and `ca_path` have been deprecated and removed from the example configuration.
73 #### Migration Path <a id="upgrading-to-2-8-certificate-paths-migration-path"></a>
77 > Icinga 2 automatically migrates the certificates to the new default location if they
78 > are configured and detected in `/etc/icinga2/pki`.
80 During startup, the migration kicks in and ensures to copy the certificates to the new
81 location. This will also happen if someone updates the certificate files in `/etc/icinga2/pki`
82 to ensure that the new certificate location always has the latest files.
84 This has been implemented in the Icinga 2 binary to ensure it works on both Linux/Unix
85 and the Windows platform.
87 If you are not using the built-in CLI commands and setup wizards to deploy the client certificates,
88 please ensure to update your deployment tools/scripts. This mainly affects
94 * Custom scripts, e.g. Windows Powershell or self-made implementations
96 In order to support a smooth migration between versions older than 2.8 and future releases,
97 the built-in certificate migration path is planned to exist as long as the deprecated
98 `ApiListener` object attributes exist.
100 You are safe to use the existing configuration paths inside the `api` feature.
104 Look at the following example taken from the Director Linux deployment script for clients.
106 * Ensure that the default certificate path is changed from `/etc/icinga2/pki` to `/var/lib/icinga2/certs`.
109 -ICINGA2_SSL_DIR="${ICINGA2_CONF_DIR}/pki"
110 +ICINGA2_SSL_DIR="${ICINGA2_STATE_DIR}/lib/icinga2/certs"
113 * Remove the ApiListener configuration attributes.
116 object ApiListener "api" {
117 - cert_path = SysconfDir + "/icinga2/pki/${ICINGA2_NODENAME}.crt"
118 - key_path = SysconfDir + "/icinga2/pki/${ICINGA2_NODENAME}.key"
119 - ca_path = SysconfDir + "/icinga2/pki/ca.crt"
120 accept_commands = true
125 Test the script with a fresh client installation before putting it into production.
129 > Please support module and script developers in their migration. If you find
130 > any project which would require these changes, create an issue or a patchset in a PR
131 > and help them out. Thanks in advance!
133 ### On-Demand Signing and CA Proxy <a id="upgrading-to-2-8-on-demand-signing-ca-proxy"></a>
135 Icinga 2 v2.8 supports the following features inside the cluster:
137 * Forward signing requests from clients through a satellite instance to a signing master ("CA Proxy").
138 * Signing requests without a ticket. The master instance allows to list and sign CSRs ("On-Demand Signing").
140 In order to use these features, **all instances must be upgraded to v2.8**.
142 More details in [this chapter](06-distributed-monitoring.md#distributed-monitoring-setup-sign-certificates-master).
144 ### Windows Client <a id="upgrading-to-2-8-windows-client"></a>
146 Windows versions older than Windows 10/Server 2016 require the [Universal C Runtime for Windows](https://support.microsoft.com/en-us/help/2999226/update-for-universal-c-runtime-in-windows).
148 ### Removed Bottom Up Client Mode <a id="upgrading-to-2-8-removed-bottom-up-client-mode"></a>
150 This client mode was deprecated in 2.6 and was removed in 2.8.
152 The node CLI command does not provide `list` or `update-config` anymore.
156 > The old migration guide can be found on [GitHub](https://github.com/Icinga/icinga2/blob/v2.7.0/doc/06-distributed-monitoring.md#bottom-up-migration-to-top-down-).
158 The clients don't need to have a local `conf.d` directory included.
160 Icinga 2 continues to run with the generated and imported configuration.
161 You are advised to [migrate](https://github.com/Icinga/icinga2/issues/4798)
162 any existing configuration to the "top down" mode with the help of the
163 Icinga Director or config management tools such as Puppet, Ansible, etc.
166 ### Removed Classic UI Config Package <a id="upgrading-to-2-8-removed-classicui-config-package"></a>
168 The config meta package `classicui-config` and the configuration files
169 have been removed. You need to manually configure
170 this legacy interface. Create a backup of the configuration
171 before upgrading and re-configure it afterwards.
174 ### Flapping Configuration <a id="upgrading-to-2-8-flapping-configuration"></a>
176 Icinga 2 v2.8 implements a new flapping detection algorithm which splits the
177 threshold configuration into low and high settings.
179 `flapping_threshold` is deprecated and does not have any effect when flapping
180 is enabled. Please remove `flapping_threshold` from your configuration. This
181 attribute will be removed in v2.9.
183 Instead you need to use the `flapping_threshold_low` and `flapping_threshold_high`
184 attributes. More details can be found [here](08-advanced-topics.md#check-flapping).
186 ### Deprecated Configuration Attributes <a id="upgrading-to-2-8-deprecated-configuration"></a>
189 --------------|------------------
190 ApiListener | cert\_path (migration happens)
191 ApiListener | key\_path (migration happens)
192 ApiListener | ca\_path (migration happens)
193 Host, Service | flapping\_threshold (has no effect)
195 ## Upgrading to v2.7 <a id="upgrading-to-2-7"></a>
197 v2.7.0 provided new notification scripts and commands. Please ensure to
198 update your configuration accordingly. An advisory has been published [here](https://www.icinga.com/2017/08/23/advisory-for-icinga-2-v2-7-update-and-mail-notification-scripts/).
200 In case are having troubles with OpenSSL 1.1.0 and the
201 public CA certificates, please read [this advisory](https://www.icinga.com/2017/08/30/advisory-for-ssl-problems-with-leading-zeros-on-openssl-1-1-0/)
202 and check the [troubleshooting chapter](15-troubleshooting.md#troubleshooting).
204 If Icinga 2 fails to start with an empty reference to `$ICINGA2_CACHE_DIR`
205 ensure to set it inside `/etc/sysconfig/icinga2` (RHEL) or `/etc/default/icinga2` (Debian).
207 RPM packages will put a file called `/etc/sysconfig/icinga2.rpmnew`
208 if you have modified the original file.
213 vim /etc/sysconfig/icinga2
215 ICINGA2_CACHE_DIR=/var/cache/icinga2
217 systemctl restart icinga2
220 ## Upgrading the MySQL database <a id="upgrading-mysql-db"></a>
222 If you want to upgrade an existing Icinga 2 instance, check the
223 `/usr/share/icinga2-ido-mysql/schema/upgrade` directory for incremental schema upgrade file(s).
227 > If there isn't an upgrade file for your current version available, there's nothing to do.
229 Apply all database schema upgrade files incrementally.
232 # mysql -u root -p icinga < /usr/share/icinga2-ido-mysql/schema/upgrade/<version>.sql
235 The Icinga 2 DB IDO feature checks the required database schema version on startup
236 and generates an log message if not satisfied.
239 **Example:** You are upgrading Icinga 2 from version `2.4.0` to `2.8.0`. Look into
240 the `upgrade` directory:
243 $ ls /usr/share/icinga2-ido-mysql/schema/upgrade/
244 2.0.2.sql 2.1.0.sql 2.2.0.sql 2.3.0.sql 2.4.0.sql 2.5.0.sql 2.6.0.sql 2.8.0.sql
247 There are two new upgrade files called `2.5.0.sql`, `2.6.0.sql` and `2.8.0.sql`
248 which must be applied incrementally to your IDO database.
251 # mysql -u root -p icinga < /usr/share/icinga2-ido-mysql/schema/upgrade/2.5.0.sql
252 # mysql -u root -p icinga < /usr/share/icinga2-ido-mysql/schema/upgrade/2.6.0.sql
253 # mysql -u root -p icinga < /usr/share/icinga2-ido-mysql/schema/upgrade/2.8.0.sql
256 ## Upgrading the PostgreSQL database <a id="upgrading-postgresql-db"></a>
258 If you want to upgrade an existing Icinga 2 instance, check the
259 `/usr/share/icinga2-ido-pgsql/schema/upgrade` directory for incremental schema upgrade file(s).
263 > If there isn't an upgrade file for your current version available, there's nothing to do.
265 Apply all database schema upgrade files incrementally.
268 # export PGPASSWORD=icinga
269 # psql -U icinga -d icinga < /usr/share/icinga2-ido-pgsql/schema/upgrade/<version>.sql
272 The Icinga 2 DB IDO feature checks the required database schema version on startup
273 and generates an log message if not satisfied.
275 **Example:** You are upgrading Icinga 2 from version `2.4.0` to `2.8.0`. Look into
276 the `upgrade` directory:
279 $ ls /usr/share/icinga2-ido-pgsql/schema/upgrade/
280 2.0.2.sql 2.1.0.sql 2.2.0.sql 2.3.0.sql 2.4.0.sql 2.5.0.sql 2.6.0.sql 2.8.0.sql
283 There are two new upgrade files called `2.5.0.sql`, `2.6.0.sql` and `2.8.0.sql`
284 which must be applied incrementally to your IDO database.
287 # export PGPASSWORD=icinga
288 # psql -U icinga -d icinga < /usr/share/icinga2-ido-pgsql/schema/upgrade/2.5.0.sql
289 # psql -U icinga -d icinga < /usr/share/icinga2-ido-pgsql/schema/upgrade/2.6.0.sql
290 # psql -U icinga -d icinga < /usr/share/icinga2-ido-pgsql/schema/upgrade/2.8.0.sql
