Installing on Ubuntu and Debian (Manual)

Esta página aún no está disponible en tu idioma.

Preliminaries

Check disk size

$ df -h

Create user named openkm

$ sudo adduser openkm

Check if partners channels are enabled

$ cat /etc/apt/sources.list

In case they are not enabled, enable them.

$ sudo vim /etc/apt/sources.list
$ sudo apt-get update

Check server configuration

$ wget -Nc smxi.org/inxi
$ sudo chmod +x inxi
$ sudo ./inxi -F

Increase ulimit

$ sudo vim /etc/pam.d/su

uncomment the following line

#session required pam_limits.so

session required pam_limits.so

$ sudo vim /etc/security/limits.conf

and add the following lines to the end of the file (before the line # End of file)

* soft nofile 6084

* hard nofile 6084

Checking Java version

$ java -version

If Java is correctly installed on your computer, the name and version of the Java virtual machine is displayed:

openjdk version "1.8.0_212"
OpenJDK Runtime Environment (build 1.8.0_212-8u212-b03-0ubuntu1.18.04.1-b03)
OpenJDK 64-Bit Server VM (build 25.212-b03, mixed mode)

Install Java

In case of Ubuntu

$ sudo apt-get update
$ sudo apt-get install openjdk-8-jdk

In case of Debian

$ su -
$ apt-get update
$ apt-get install openjdk-8-jdk
$ exit

Set OpenJDK 1.8 as your default Java version

$ sudo update-alternatives --config java

Installing database

Install MySQL if you do not have it already installed:

$ sudo apt-get install mysql-server

When you install MySQL, the installer will ask you for a password for the root user. Keep this password handy.

Also you can install MariaDB, which replaces MySQL in latest versions:

$ sudo apt-get install mariadb-server

Change MySQL root password

Do it only if it’s necessary to change MySQL root password.

Method 1

$ /usr/bin/mysqladmin -u root -h localhost password 'password'

Method 2

$ sudo /etc/init.d/mysql stop
$ sudo mysqld --skip-grant-tables &
$ mysql -u root mysql
> UPDATE user SET Password=PASSWORD('YOURNEWPASSWORD') WHERE User='root';
> FLUSH PRIVILEGES;
> exit;

Method 3

$ mysql
> UPDATE mysql.user SET Password=PASSWORD('MyNewPass') WHERE User='root';
> flush privileges;

Method 4

$ sudo /etc/init.d/mysql stop
$ mysqld_safe --skip-grant-tables &
$ mysql -u root mysql
> UPDATE user SET Password=PASSWORD('YOURNEWPASSWORD') WHERE User='root';
> FLUSH PRIVILEGES;
> exit;

More information at MySQL : Reseting permissions.

Check InnoDB is default MySQL engine

$ mysql -h localhost -u root -p
> show engines;

If it not default, modify /etc/mysql/my.cnf

$ vim /etc/mysql/my.cnf

and under [mysqld] add

default-storage-engine = innodb

Create database

CREATE DATABASE okmdb DEFAULT CHARACTER SET utf8 DEFAULT COLLATE utf8_bin;
CREATE USER openkm@localhost IDENTIFIED BY 'password';
GRANT ALL ON okmdb.* TO openkm@localhost WITH GRANT OPTION;

Installing Tomcat

$ cd /home/openkm
$ unzip Tomcat-8.5.24.zip

Configuring Tomcat as a service

Create a file with the script:

$ sudo vim /etc/init.d/tomcat

#!/bin/sh

### BEGIN INIT INFO
# Provides:          tomcat
# Required-Start:    $remote_fs $syslog
# Required-Stop:     $remote_fs $syslog
# Default-Start:     2 3 4 5
# Default-Stop:      0 1 6
# Short-Description: Start and stop Apache Tomcat
# Description:       Enable Apache Tomcat service provided by daemon.
### END INIT INFO

ECHO=/bin/echo
TEST=/usr/bin/test
TOMCAT_USER=openkm
TOMCAT_HOME=/home/openkm/tomcat-8.5.24
TOMCAT_START_SCRIPT=$TOMCAT_HOME/bin/startup.sh
TOMCAT_STOP_SCRIPT=$TOMCAT_HOME/bin/shutdown.sh

$TEST -x $TOMCAT_START_SCRIPT || exit 0
$TEST -x $TOMCAT_STOP_SCRIPT || exit 0

start() {
    $ECHO -n "Starting Tomcat"
    su - $TOMCAT_USER -c "$TOMCAT_START_SCRIPT &"
    $ECHO "."
}

stop() {
    $ECHO -n "Stopping Tomcat"
    su - $TOMCAT_USER -c "$TOMCAT_STOP_SCRIPT 60 -force &"
    while [ "$(ps -fu $TOMCAT_USER | grep java | grep tomcat | wc -l)" -gt "0" ]; do
        sleep 5; $ECHO -n "."
    done
    $ECHO "."
}

case "$1" in
    start)
        start
        ;;
    stop)
        stop
        ;;
    restart)
        stop
        sleep 30
        start
        ;;
    *)
        $ECHO "Usage: tomcat {start|stop|restart}"
        exit 1
esac
exit 0

Make it executable:

$ sudo chmod 755 /etc/init.d/tomcat

Update the run-levels:

$ sudo update-rc.d tomcat defaults

Check the service

Start the service:

$ sudo service tomcat start

Stop the service:

$ sudo service tomcat stop

Installing OpenKM

With tomcat stopped copy the OpenKM.war file into /home/openkm/tomcat-8.5.24/webapps

$ cp OpenKM.war /home/openkm/tomcat-8.5.24/webapps

Installing third-party software

Software	Required	Command
LibreOffice or OpenOffice	Yes	`bash<br>$ apt-get install libreoffice<br>`
Tesseract	No	`bash<br>$ apt-get install tesseract-ocr tesseract-ocr-eng<br>` Depending on your locale you would like to install other language file.
Clamav	No	`bash<br>$ apt-get install clamav<br>`
Imagemagick	Yes	`bash<br>$ apt-get install imagemagick<br>`
Ghostscript	Yes	`bash<br>$ apt-get install ghostscript<br>`

Start application

Check OpenKM.cfg parameters

$ vim /home/openkm/tomcat-8.5.24/OpenKM.cfg

Your configuration should be something like this:

# OpenKM Hibernate configuration values
hibernate.dialect=org.hibernate.dialect.MySQL5InnoDBDialect
hibernate.hbm2ddl=create

First time application start:

$ service tomcat start

To see the startup process can execute the command:

$ tail -f /home/openkm/tomcat-8.5.24/log/catalina.log

When application is started you’ll see in log file the lines:

2015-07-04 18:28:10,680 [main] INFO  org.apache.coyote.http11.Http11Protocol - Starting ProtocolHandler ["http-bio-0.0.0.0-8080"]
2015-07-04 18:28:10,688 [main] INFO  org.apache.coyote.ajp.AjpProtocol - Starting ProtocolHandler ["ajp-bio-127.0.0.1-8009"]
2015-07-04 18:28:10,692 [main] INFO  org.apache.catalina.startup.Catalina - Server startup in 41456 ms

The application will be accessible at http://YOUR_IP:8080/OpenKM by user:okmAdmin with password:admin. ( Do not forget to change it !). For more information about Manage users and roles.

Configure default extensions:

Go to Administration > Utilities > Database query and execute:

INSERT INTO OKM_EXTENSION (EXT_UUID, EXT_NAME) VALUES ('808e7a42-2e73-470c-ba23-e4c9d5c3a0f4', 'Live Edit');
INSERT INTO OKM_EXTENSION (EXT_UUID, EXT_NAME) VALUES ('58392af6-2131-413b-b188-1851aa7b651c', 'HTML Editor 4');
INSERT INTO OKM_PROFILE_MSC_EXTENSION (PEX_ID, PEX_EXTENSION) VALUES (1, '808e7a42-2e73-470c-ba23-e4c9d5c3a0f4');
INSERT INTO OKM_PROFILE_MSC_EXTENSION (PEX_ID, PEX_EXTENSION) VALUES (1, '58392af6-2131-413b-b188-1851aa7b651c');

Other common additional configurations setup

OpenKM comes with a lot of configuration parameters. Please make sure to review: Recommended configuration parameters.
