I will describe here, step by step, my installation of SignServer 4.0.0 (https://www.signserver.org/) on GNU/Linux Debian 9. When writing this document, I used Debian 9.4

So let's start and assume you have an up-to-date operating system. We will install WildFly as application server and for testing we will create our own PKI using openssl tool. We will also using MariaDB as database server.

Official install guide is https://www.signserver.org/doc/current/manual/installguide.html

apt-get install unzip openjdk-8-jdk ant

Do not install MariaDB from debian repository, because we need to use at least version 10.2.2 (otherwise index key prefix length is will be a problem https://stackoverflow.com/questions/45822688/key-was-too-long-in-mariadb-but-same-script-with-same-encoding-works-on-mysql).

We will create a jboss user which will execute the application server WildFly.

addgroup jboss
adduser  --disabled-password --home /home/jboss --shell /bin/bash --ingroup jboss jboss

I do not configure password for this account, not needed. I will just add my SSH key to his authorized_keys file :

mkdir /home/jboss/.ssh
vi /home/jboss/.ssh/authorized_keys
chown jboss.jboss /home/jboss/.ssh -R
chmod og-r /home/jboss/.ssh/authorized_keys 

When editing authorized_keys file, just add your SSH key.

Download SignServer 4.0.0 archive (binary edition) : https://www.signserver.org/download.html

wget https://sourceforge.net/projects/signserver/files/signserver/4.0/signserver-ce-4.0.0-bin.zip

And unzip it in /opt directory

unzip signserver-ce-4.0.0-bin.zip -d /opt
ln -s /opt/signserver-ce-4.0.0 /opt/signserver
chown jboss.jboss /opt/signserver* -R

From WildFly download page http://wildfly.org/downloads/, get the 9.0.2.Final version :

wget http://download.jboss.org/wildfly/9.0.2.Final/wildfly-9.0.2.Final.tar.gz

Unpack archive in /opt directory

tar xfz wildfly-9.0.2.Final.tar.gz -C /opt
ln -s /opt/wildfly-9.0.2.Final /opt/wildfly
chown jboss.jboss /opt/wildfly* -R

Edit jboss .bashrc to add environment variables :

vi /home/jboss/.bashrc

and add at the end of the file :

export APPSRV_HOME=/opt/wildfly
export SIGNSERVER_NODEID=node1

We need to install MariaDB server version >= 10.2.2. It was not possible to install such mariadb version from debian repository.

From https://mariadb.com/downloads/mariadb-tx, download current debian version (release = current / version = 10.2.14 GA / OS = debian / OS Version = Debian 9 (Stretch))

wget https://downloads.mariadb.com/MariaDB/mariadb-10.2.14/repo/debian/mariadb-10.2.14-debian-stretch-amd64-debs.tar

Unpack and install :

tar xf mariadb-10.2.14-debian-stretch-amd64-debs.tar
cd mariadb-10.2.14-debian-stretch-amd64-debs
./setup_repository
apt-get update && apt-get install mariadb-server

Create database :

mysql -u root -p mysql

create database signserver;
grant all on signserver.* to "signserver"@"localhost" identified by "signserver";
flush privileges;
quit

We need to install MariaDB java connector to wildfly. From https://mariadb.com/downloads/mariadb-tx/connector, download the connector (type = database client / language = java / version = 2.2.3 GA)

wget https://downloads.mariadb.com/Connectors/java/connector-java-2.2.3/mariadb-java-client-2.2.3.jar
mkdir -p /opt/wildfly/modules/system/layers/base/org/mariadb/main/
mv mariadb-java-client-2.2.3.jar /opt/wildfly/modules/system/layers/base/org/mariadb/main/

Create the file module.xml

vi /opt/wildfly/modules/system/layers/base/org/mariadb/main/module.xml

<?xml version="1.0" encoding="UTF-8"?>
<module xmlns="urn:jboss:module:1.0" name="org.mariadb">
  <resources>
      <resource-root path="mariadb-java-client-2.2.3.jar"/>
  </resources>
  <dependencies>
      <module name="javax.api"/>
      <module name="javax.transaction.api"/>
  </dependencies>
</module>

chown jboss.jboss -R /opt//wildfly*

Connect as user jboss. From root, use sudo, or connect via SSH. I recommand you to use another terminal, because we will launch wildfly ni foreground (and be able to see all log information).

sudo -u jboss -s

And start standalone wildfly

cd /opt/wildfly
./bin/standalone.sh

Open another terminal with jboss user connected in, and launch jboss CLI :

cd /opt/wildfly
./bin/jboss-cli.sh

then connect (just typing connect after [disconnected /] prompt)

You are disconnected at the moment. Type 'connect' to connect to the server or 'help' for the list of supported commands.
[disconnected /]  connect
[standalone@localhost:9990 /] 

Register the mariadb connector (in jboss CLI) :

[standalone@localhost:9990 /] /subsystem=datasources/jdbc-driver=org.mariadb.jdbc.Driver:add(driver-name=org.mariadb.jdbc.Driver,driver-module-name=org.mariadb,driver-xa-datasource-class-name=org.mariadb.jdbc.MySQLDataSource)
{"outcome" => "success"}
[standalone@localhost:9990 /] :reload
{
    "outcome" => "success",
    "result" => undefined
}

And then configure database (in jboss CLI) :

In this command, you can see the mariadb username, password and database name we used when create database. Change here if you choose another values.

[standalone@localhost:9990 /] data-source add --name=signserverds --driver-name="org.mariadb.jdbc.Driver" --connection-url="jdbc:mysql://127.0.0.1:3306/signserver" --jndi-name="java:/SignServerDS" --use-ccm=true --driver-class="org.mariadb.jdbc.Driver" --user-name="signserver" --password="signserver" --validate-on-match=true --background-validation=false --prepared-statements-cache-size=50 --share-prepared-statements=true --min-pool-size=5 --max-pool-size=150 --pool-prefill=true --transaction-isolation=TRANSACTION_READ_COMMITTED --check-valid-connection-sql="select 1;"
[standalone@localhost:9990 /] shutdown

Last shutdown command will stop wildfly application server. Just restart it in first jboss terminal with standalone.sh script.

From our own PKI (see PKI.md), create a certificate for the wildfly service. The common name of the certificate must be the same as the FQDN you will use in the service url.

Create a keystore which will contains the wildfly SSL certificate :

mkdir /opt/wildfly/standalone/configuration/keystore
keytool -importkeystore -deststorepass keystorepwd  -destkeypass keystorepwd -destkeystore /opt/wildfly/standalone/configuration/keystore/wildfly.keystore.jks -srckeystore /opt/pki/certificats/wildfly.p12 -srcstoretype PKCS12 -srcstorepass p12secret -alias wildfly

I choose keystorepwd as keystore password. Be carefull, deststorepass and destkeypass must be the same. Otherwise wildfly will not be able to retrieve key file. Change srcstorepass with your p12 export password.

You can migrate the keystore as warning message tell you :

keytool -importkeystore -srckeystore /opt/wildfly/standalone/configuration/keystore/wildfly.keystore.jks -destkeystore /opt/wildfly/standalone/configuration/keystore/wildfly.keystore.jks -deststoretype pkcs12

Use keystore password choose previously (keystorepwd for me)

Now, we have to create the truststore file which will contains users certificate. They will be able to connect to HTTPs private area with they own certificate (SSL connection will verify the client certificate).

keytool -alias john.smith -import -file /opt/pki/certificats/user.john.crt -keystore /opt/wildfly/standalone/configuration/keystore/truststore.jks

I choose trustpwd as truststore password.

You need need also to import the certificat of the CA in the user certificat chain. In our example, just import the ca.crt

keytool -alias myownca -import -file /opt/pki/certificats/ca.crt -keystore /opt/wildfly/standalone/configuration/keystore/truststore.jks

chown jboss.jobss /opt/wildfly* -R

We are now able to configure wildfly SSL. For that, we will use the jboss CLI (under user jboss). So return to the terminal in which you previously launch the jboss CLI.

(code starting with [standalone@localhost:9990 /] must be paste into jboss CLI)

[standalone@localhost:9990 /]
 /interface=http:add(inet-address="0.0.0.0")
/interface=httpspub:add(inet-address="127.0.0.1")
/interface=httpspriv:add(inet-address="0.0.0.0")

Secure the CLI by removing the http-remoting-connector from using the http port and instead use a separate port 4447.

[standalone@localhost:9990 /]
/subsystem=remoting/http-connector=http-remoting-connector:remove
/subsystem=remoting/http-connector=http-remoting-connector:add(connector-ref="remoting",security-realm="ApplicationRealm")
/socket-binding-group=standard-sockets/socket-binding=remoting:add(port="4447")
/subsystem=undertow/server=default-server/http-listener=remoting:add(socket-binding=remoting)
:reload

[standalone@localhost:9990 /]
/socket-binding-group=standard-sockets/socket-binding=httpspriv:add(port="8443",interface="httpspriv")
/core-service=management/security-realm=SSLRealm:add()
/core-service=management/security-realm=SSLRealm/server-identity=ssl:add(keystore-path="keystore/wildfly.keystore.jks", keystore-relative-to="jboss.server.config.dir", keystore-password="keystorepwd", alias="wildfly")
/core-service=management/security-realm=SSLRealm/authentication=truststore:add(keystore-path="keystore/truststore.jks", keystore-relative-to="jboss.server.config.dir", keystore-password="trustpwd")
/subsystem=undertow/server=default-server/https-listener=httpspriv:add(socket-binding="httpspriv", security-realm="SSLRealm", verify-client=REQUIRED)

Pay attention to the third and the fourth command :

3. keystore-password must be the password you choose to use when creating the wildfly.keystore.jks file. Alias is the alias you choose when importing the wildfly SSL certificate.
4. keystore-password must be the password you choose to use when creating the truststore.jks file.

Set-up the public SSL port which doesn't require the client certificate

[standalone@localhost:9990 /]
/socket-binding-group=standard-sockets/socket-binding=httpspub:add(port="8442",interface="httpspub")
/subsystem=undertow/server=default-server/https-listener=httpspub:add(socket-binding="httpspub", security-realm="SSLRealm")

Then reload all the configuration change

reload

Hope you do not have red message in wildfly console.

Port 8443 and 8442 must be open. Command netstat -taonp will help you to check for it.

Fix web service problem in JBoss AS 7/EAP 6/WildFly

Configure WSDL web-host rewriting to use the request host. Needed for webservices to work correctly when requiring client certificate.

[standalone@localhost:9990 /]
/subsystem=webservices:write-attribute(name=wsdl-host, value=jbossws.undefined.host)
/subsystem=webservices:write-attribute(name=modify-wsdl-address, value=true)

If the server is not so fast, we have to wait a little before we can reload, otherwise it will be bad

[standalone@localhost:9990 /]
:reload

Copy conf/signserver_deploy.properties.sample to conf/signserver_deploy.properties and open it for editing.

cp /opt/signserver/conf/signserver_deploy.properties.sample /opt/signserver/conf/signserver_deploy.properties
vi /opt/signserver/conf/signserver_deploy.properties

Uncomment lines :

appserver.home=${env.APPSRV_HOME}
database.name=mysql

chown jboss.jboss /opt/signserver* -R

As user jboss, deploy configuration :

cd /opt/signserver
./bin/ant deploy

Check signserver version :

bin/signserver getstatus brief all
Current version of server is : SignServer EE 4.0.0

This work will manage key used to sign. It will store key as p12 (in order to have private and public key).

We will create a store with a generic key pair.

Create the keystore including the generic certificate :

mkdir /opt/signserver/myconfig
keytool -importkeystore -deststorepass keystorepwd  -destkeypass keystorepwd -destkeystore /opt/signserver/myconfig/worker.crypto.keystore.jks -srckeystore /opt/pki/certificats/crypto.generic.p12 -srcstoretype PKCS12 -srcstorepass generic -alias generic
keytool -importkeystore -srckeystore /opt/signserver/myconfig/worker.crypto.keystore.jks -destkeystore /opt/signserver/myconfig/worker.crypto.keystore.jks -deststoretype pkcs12

Create the properties file /opt/signserver/myconfig/worker-crypto.properties.

Defaultkey is the name of the generic certificate imported in the keystore (-alias generic)

Import the configuration into SignServer :

cd /opt/signserver
./bin/signserver setproperties /opt/signserver/myconfig/worker

Check worker status :

bin/signserver getstatus brief all
Current version of server is : SignServer CE 4.0.0

Status of CryptoWorker with id 1 (MyCryptoTokenP12) is:
   Worker status : Active
   Token status  : Active

Activate the CrytoToken worker :

bin/signserver activatecryptotoken 1

Create the file /opt/signserver/myconfig/worker-xmlsigner.properties

and import it :

cd /opt/signserver
./bin/signserver setproperties myconfig/worker-xmlsigner.properties

Check status and retrieve worker id (ie 2)

./bin/signserver getstatus brief all

You must see Worker status and Token status = Active. Hoping so.
