Maven-3 is required, download and extract if not installed using distribution package management, and add to PATH.
WildFly 11 is required along with ovirt-engine-wildfly-overlay. Preferred way is to install following packages:
ovirt-engine-wildfly
ovirt-engine-wildfly-overlay
Both packages can be installed from ovirt-master-snapshot-static repository:
[ovirt-master-snapshot-static] name=Latest oVirt master additional nightly snapshot baseurl=http://resources.ovirt.org/pub/ovirt-master-snapshot-static/rpm/@DIST@$releasever/ enabled=1 skip_if_unavailable=1 gpgcheck=0
Please replace @DIST@
with fc
for Fedora or el
for Centos/RHEL.
OVN/OVS is an optional dependency. If you want to use it, check the requirements in the ovirt-engine.spec.in file for a list of packages. Otherwise, you should reply 'No' when asked about it by engine-setup.
Build locales requires at least 10240 file descriptors, create the following file, replace <user> with user that is used for building, and logout/login:
<user> hard nofile 10240
#<user> soft nofile 10240 # optional, to apply automatically
If soft limit was not set, before building, apply new limit using:
$ ulimit -n 10240
Configure PostgreSQL to accept user and password:
Locate pg_hba.conf
within your distribution, common locations are:
/var/lib/pgsql/data/pg_hba.conf
/etc/postgresql-*/pg_hba.conf
/etc/postgresql/*/main/pg_hba.conf
/var/opt/rh/rh-postgresql95/lib/pgsql/data/pg_hba.conf
(el7 with rh-postgresql95)
Within pg_hba.conf
set method to password
for 127.0.0.1/32
and
::1/128
.
Tune PostgreSQL configuration:
Locate postgresql.conf
within your distribution, common locations are:
/var/lib/pgsql/data
/etc/postgresql*
/var/opt/rh/rh-postgresql95/lib/pgsql/data/postgresql.conf
(el7 with rh-postgresql95)
Within postgresql.conf
set:
autovacuum_vacuum_scale_factor = 0.01 autovacuum_analyze_scale_factor = 0.075 autovacuum_max_workers = 6 max_connections = 150 work_mem = 8192
Restart the PostgreSQL service (systemctl restart rh-postgresql95-postgresql
for the SCL one).
Create database for ovirt-engine, usually the following sequence should
work to create a user named engine
that owns database named engine
:
# su - postgres -c "psql -d template1" # if on fedora or # su - postgres -c "scl enable rh-postgresql95 -- psql -d template1" # if on el7 with rh-postgresql95 template1=# create user engine password 'engine'; template1=# drop database engine; template1=# create database engine owner engine template template0 encoding 'UTF8' lc_collate 'en_US.UTF-8' lc_ctype 'en_US.UTF-8';
Development environment is supported only under non-root account. Do not run this sequence as root.
Each instance of application must be installed at different PREFIX
and
use its own database. Throughout this document application is installed
using PREFIX="${PREFIX}"
and engine database and user, these should be
changed if a new instance is required. Do not mix different versions of
product with same PREFIX/database
.
From this point on, the "${PREFIX}"
will be used to mark the prefix
in which you selected to install the development environment.
To build and install ovirt-engine at your home folder under ovirt-engine directory execute the following command:
$ make clean install-dev PREFIX="${PREFIX}"
Note
|
${PREFIX} should be replaced with the location in which you
intend to install the environment.
|
Note
|
Add DEV_BUILD_SCL_POSTGRESQL=1 in order to configure your local build for SCL rh-postgresql95. |
Build project.
Clean project.
Build project for development.
Install a development environment at PREFIX.
Create source tarball out of git repository.
Force execution of maven.
The following Makefile
environment variables are available for build
customization:
Installation root directory. Default is /usr/local
.
Build GWT. Default is 1
.
Build GWT applications for all supported
browsers. Default is 0
.
Build GWT applications for all supported locales.
default is 0
.
Add extra development flags. Usually this should not be
used directly, as the all-dev sets this. Default is 0
.
Perform unit tests during build. Default is 0
.
Maven JVM options. Can be defined as environment variable. Default is empty.
GWT compiler and dev mode JVM options. Can be defined as environment variable. default is empty.
Note
|
Note that BUILD_JAVA_OPTS_GWT overrides BUILD_JAVA_OPTS_MAVEN
when building GWT applications (BUILD_JAVA_OPTS_MAVEN settings still
apply, unless overridden).
|
Build "draft" version of GWT applications without
optimizations. This is useful when profiling compiled applications in
web browser. Default value is 0
.
Following changes are applied for draft builds: - Prevent code and CSS obfuscation. - Reduce the level of code optimizations.
+ On local development environment, using GWT Super Dev Mode (see below) is preferred, as it automatically disables all optimizations and allows you to recompile the GWT application on the fly.
Configure your local development deployment
to be used with SCL rh-postgresql95 instead of system PostgreSQL.
Default value is 0
.
Allows debugging GWT applications via
Super Dev Mode, using web browser’s JavaScript development tooling.
Default value is 0
.
Do a local Engine development build as you normally would. Then, start the Super Dev Mode code server as following:
$ make gwt-debug DEV_BUILD_GWT_SUPER_DEV_MODE=1
In your browser, open http://127.0.0.1:9876/ and save the "Dev Mode On" bookmark. Next, visit the GWT application URL (as served from Engine) and click "Dev Mode On". This allows you to recompile and reload the GWT application, reflecting any changes you’ve made in the UI code.
Any maven build flags required for building.
For example, if your machine is low on memory, limit maximum simultaneous GWT permutation worker threads:
DEV_EXTRA_BUILD_FLAGS="-Dgwt.compiler.localWorkers=1"
Any maven build flags required for building GWT applications.
By default, GWT applications are
built for Firefox only. To build for additional browsers, provide
comma-separated list of user agents, see
frontend/webadmin/modules/pom.xml
for full list.
For example, to build for Firefox and Chrome:
DEV_EXTRA_BUILD_FLAGS_GWT_DEFAULTS="-Dgwt.userAgent=gecko1_8,safari"
To build for all supported browsers, use BUILD_ALL_USER_AGENTS=1
.
For example, to build only the English and Japanese locale:
DEV_EXTRA_BUILD_FLAGS_GWT_DEFAULTS="-Dgwt.locale=en_US,ja_JP"
To build for all supported locales, use BUILD_LOCALES=1
.
Disable if only packaging components were modified.
Default is 1
.
Change location of WildFly overlay modules.
If you want to disable WildFly overlay configuration completely, please
set to empty string. Default is
/usr/share/ovirt-engine-wildfly-overlay/modules
.
If you want to use different WildFly/EAP installation, specify it at
--jboss-home=
parameter of setup.
Select a specific Java home.
Set to non zero to bypass Java compatibility check.
If there are no significant changes, such as file structure or database
schema, there is no need to run the setup again, make install-dev
<args>
will overwrite files as required, run engine-setup
to refresh
database schema.
Do remember to restart the engine service.
If there is a significant change, safest path is to stop service, remove
${PREFIX}
directory, build and setup.
The ${PREFIX}/bin/engine-cleanup
tool is also available to cleanup the
environment, it is useful for application changes, less for packaging
changes.
Most utilities and services are operational, including PKI, host deploy.
To start/stop the engine service use:
$ "${PREFIX}/share/ovirt-engine/services/ovirt-engine/ovirt-engine.py" start
While the service is running, this command will not exit. Press <Ctrl>-C to stop service.
Access using HTTP or HTTPS:
Debug port is available at 127.0.0.1:8787
.
ovirt-engine service supports jmx as management interface. Actually, this is the standard jboss jmx interface, while authentication can be done using any engine user with SuperUser role. Access is permitted only from the local host.
Access JMX shell using provide OPTIONAL_COMMAND for non interactive usage:
$ "${JBOSS_HOME}/bin/jboss-cli.sh" \ --connect \ --timeout=30000 \ --controller=localhost:8706 \ --user=admin@internal \ --commands="OPTIONAL_COMMA_SEPARATED_COMMANDS"
Useful commands:
/subsystem=logging/logger=org.ovirt.engine.core.bll:write-attribute(name=level,value=DEBUG)
/subsystem=logging/logger=org.ovirt.engine:add
ls /subsystem=datasources/data-source=ENGINEDataSource/statistics=jdbc/
ls /core-service=platform-mbean/type=threading/
By default JMX access is available only to localhost, to open JMX to
world, add ${PREFIX}/etc/ovirt-engine/engine.conf.d/20-setup-jmx-debug.conf
with:
ENGINE_JMX_INTERFACE=public
$ make install-dev PREFIX="${PREFIX}" $ make gwt-debug
Debug port is 8000, detailed instructions for GWT debugging are here.
GWT debug URL, provided components running on same machine:
Note that gwt.codesvr
parameter does not apply when using Super Dev Mode.
Create empty database for DAO tests refer to Database creation.
Provided user is engine
, password is engine
and database is
engine_dao_tests
.
$ PGPASSWORD=engine \ ./packaging/dbscripts/schema.sh \ -c apply -u engine -d engine_dao_tests
Run build as:
$ make maven BUILD_GWT=0 BUILD_UT=1 EXTRA_BUILD_FLAGS="-P enable-dao-tests \ -D engine.db.username=engine \ -D engine.db.password=engine \ -D engine.db.url=jdbc:postgresql://localhost/engine_dao_tests"
After the environment is setup and installed, some adjustments are required.
Copy vmconsole-host
configuration:
$ sudo cp -p "${PREFIX}/share/ovirt-engine/conf/ovirt-vmconsole-proxy.conf \ /etc/ovirt-vmconsole/ovirt-vmconsole-proxy/conf.d/50-ovirt-vmconsole-proxy.conf
If selinux is enabled on your machine, set type on vmconsole helper using:
$ sudo chcon --type=bin_t "${PREFIX}/libexec/ovirt-vmconsole-proxy-helper/ovirt-vmconsole-list.py"
$ make dist $ rpmbuild -ts @tarball@ # yum-builddep @srpm@ # rpmbuild -tb @tarball@
The following spec file variables are available for package customization:
Quick build, best for syntax checks. Default is 0
.
Build minimal Firefox only package. Default is
0
.
Build GWT components. Default is 1
.
Build GWT components for all supported
browsers. Default is 1
.
Build GWT components for all supported locales.
