This tutorial shows you how to prepare the server for test or production use of CzechIdM. If you are looking for a much quicker way of installing CzechIdM, use the demo setup described here Getting Started

• 1 server (can be virtualized) for everything: backend, frontend and database.
• OS Windows, ideally W2012 and newer
• PostgreSQL - installed from OpenSCG
• Java - installed from Oracle JDK
• Apache Tomcat - installed by Tomcat .exe installer
• Services start via system services (services.msc)

Prerequisities - Basic installation of Windows Server 2012.

• Install the Telnet Client system feature through Programs and Features. This is optional but greatly helps with debugging network problems.
• Install Firefox. Also optional, but greatly helps with debugging IdM webapp problems.
• Install Git Bash. This will be essential when configuring IdM and checking its logs.
  • Use checkout-windows, commit unix style endings. It does not really matter, we will not use the git command for anything.:)
  • Do not enable integration with windows cmd.
• Disable unnecessary windows services.
• Disable Microsoft IIS if installed.

On Windows, we use OpenSCG PostgreSQL distribution, version at least 9.6.

• Leave locations at default.
• Make sure you check the option to install the windows service.

Open the elevated shell (right-click on cmd and select "run as admin") and install the pgAdmin:

cd c:/postgresql
pgc install pgadmin3

If your server does not have Internet access, you can download and install pgAdmin from here.

Edit the PostgreSQL configuration file C:\PostgreSQL\data\pg96\postgresql.conf to make it listen on 127.0.0.1 only. Adjust the database sizing as necessary. The following example is for 6GB RAM. Do not hasten to overwrite your PgSQL configuration out of hand! When in doubt, use a calculator.

listen_addresses = '127.0.0.1'		# what IP address(es) to listen on;
port = 5432				# (change requires restart)
max_connections = 150			# (change requires restart)
superuser_reserved_connections = 3	# (change requires restart)
shared_buffers = 512MB			# min 128kB
work_mem = 12815kB			# min 64kB
maintenance_work_mem = 384MB
dynamic_shared_memory_type = windows	# the default is the first option
wal_level = hot_standby
wal_buffers = 16MB			# min 32kB, -1 sets based on shared_buffers
max_wal_size = 2GB
min_wal_size = 1GB
checkpoint_completion_target = 0.7	# checkpoint target duration, 0.0 - 1.0
max_wal_senders = 5
wal_keep_segments = 32
max_replication_slots = 5
effective_cache_size = 4608MB
default_statistics_target = 100		# range 1-10000
logging_collector = on
log_directory = 'C:/POSTGR~1/data/logs/pg96'
log_filename = 'postgresql-%a.log'
log_truncate_on_rotation = on 
log_checkpoints = on
log_line_prefix =  '%t [%p]: [%l-1] user=%u,db=%d,app=%a,client=%h '
log_lock_waits = on
log_temp_files = 0
log_timezone = 'Europe/Belgrade'
update_process_title = off
track_io_timing = on
log_autovacuum_min_duration = 0
datestyle = 'iso, mdy'
timezone = 'Europe/Belgrade'
lc_messages = 'English_United States.1252'			# locale for system error message
lc_monetary = 'English_United States.1252'			# locale for monetary formatting
lc_numeric = 'English_United States.1252'			# locale for number formatting
lc_time = 'English_United States.1252'				# locale for time formatting
default_text_search_config = 'pg_catalog.english'

Configure the authentication in the C:\PostgreSQL\data\pg96\pg_hba.conf to accept passwords. The basic configuration file should then look like this:

# TYPE  DATABASE        USER            CIDR-ADDRESS            METHOD

# IPv4 local & remote connections:
host    all             all             127.0.0.1/32            md5
host    all             all             0.0.0.0/0               md5
# IPv6 local connections:
host    all             all             ::1/128                 md5

Open Windows services' dialogue (Win+r and type services.msc therein). Look for the "PostgreSQL 9.6 Server" service and set its StartupType to Automatic. Then start the service.

Install the Oracle JDK (minimal version is 1.8). You can download it from here. Be sure to download the JDK, and not only JRE.

Install the Java into a standard directory in Program Files. Having finished the installation, it is necessary to set up JAVA\_HOME and PATH variables. Open the sysdm.cpl (Win+r ant type sysdm.cpl) dialogue and navigate to > Advanced > Environment Variables. Add system-wide variable JAVA\_HOME=C:\Program Files\Java\jdk1.8.0\_152 (adjust the path accordingly to the Java version you just installed). Add the %JAVA_HOME%\bin to the PATH. Then run java -version from the windows cmd to check if it is working properly.

Download and install the latest 8.5 branch of Apache Tomcat from here. Use the Windows installer.

• Leave the installation paths on default.
• Let the setup create admin user for the Tomcat console.
• Modify the JRE path to make it point to installe Oracle JDK.
• Do not install the example application.
• Let the setup create a Tomcat windows service.

After installation, run the Monitor Tomcat application from the Start menu. Configure following settings:

• initial memory pool: 512MB (example for about 5GB RAM).
• maximum memory pool: 4096MB (example for about 5GB RAM).
• Add C:\CzechIdM\etc;C:\CzechIdM\lib;C:\CzechIdM\lib\\*; to the beginning of the CLASSPATH.

Configure addresses the server will listen on. Open the server.xml configuration file in the Tomcat installation. Make these changes:

• Add address="127.0.0.1" to the 8080/tcp and 8009/tcp connectors. This will make Tomcat listen only on localhost.
• Change port number 8005 to -1 at the Shutdown Port setting. This will effectively turn off the shutdown port.

Use the services.msc dialogue to set the Apache Tomcat StartupType to Automatic (Delayed Start). This will make the application container start after the PostgreSQL database.

For roles and advanced management configuration, please see the relevant chapters in the Server Preparation - Linux tutorial.

It is possible to open Apache Tomcat to the network directly, but somewhat inconvenient. You want the users to access CzechIdM on user-friendly ports 80/tcp or 443/tcp. So we use Apache httpd as a reverse proxy and add a few security features along the way. Apache httpd will allow access to data via https on port 443/tcp and http on port 80/tcp. Communication via http protocol is enabled, but we redirect all communication to https. Communication between Apache httpd and Tomcat takes place on local machine via AJP protocol. In httpd, there will be mod_security installed (optional but recommended), which serves as an application firewall.

The configuration example is written for the server which allows access to its services under the name "demo.czechidm.com".

First, install necessary VCredist library.

Download Apache HTTPd from the apachelounge distribution and unpack it into C:\apache24 folder.

Fire up an elevated shell and install the Apache HTTPd service:

cd C:\apache24\bin
httpd.exe -k install

Open the services.msc and reconfigure "Apache2.4" service to have StartupType=Automatic (Delayed start).

Configure the HTTPd in its core config file C:\Apache24\conf\httpd.conf. You can use the following file, just replace values for ServerAdmin and ServerName.

httpd.conf

ServerRoot "c:/Apache24"

Supply SSL certificate and key in x509 PEM form to c:/Apache24/conf/server.key and c:/Apache24/conf/server.crt files. Apache HTTPd will not start without those files. If you need to generate some ad-hoc certificates, use for example this guide. You can easily invoke the openssl tool from the Git Bash prompt.

Download the mod\_security module from the Apache Lounge project. Unpack the zip and perform following actions:

• Copy the mod\_security2.so int C:\Apache24\modules directory.
• Copy libcurl.dll and yajl.dll into C:\Apache24\bin directory.

Create general mod\_security configuration file C:\Apache24\conf\extra\modsec.conf:

modsec.conf

Create empty directories C:\Apache24\modsec\_tmp and C:\Apache24\modsec\_lib for mod_security working data.

Mod\_security will become operational but will have no filtering rules. To obtain filtering rules, please visit Mod Security project homepage. Remember to obtain 2.x version of rules, not the newest 3.x version!

Now you can start the Apache HTTPd using its service. If it fails to start, check the Windows EventLog for errors.
