OMERO.server installation on CentOS 7 and Ice 3.6 ================================================= This is an example walkthrough for installing OMERO on CentOS 7, using a dedicated system user, and should be read in conjunction with :doc:`install-web`. You can use this as a guide for setting up your own test server. For production use you should also read the pages listed under :ref:`index-optimizing-server`. These instructions assume your Linux distribution is configured with a UTF-8 locale (this is normally the default). For convenience in this walkthrough the main OMERO configuration options have been defined as environment variables. When following this walkthrough you can either use your own values, or alternatively source the following file: .. literalinclude:: walkthrough/settings.env :start-after: Substitute :download:`settings.env ` Installing prerequisites ------------------------ **The following steps are run as root.** Install Java 1.8, Ice 3.6 and PostgreSQL 9.4: To install Java 1.8 and other dependencies: .. literalinclude:: walkthrough/walkthrough_centos7.sh :start-after: #start-step01 :end-before: # install Ice To install Ice 3.6: .. literalinclude:: walkthrough/walkthrough_centos7.sh :start-after: #start-supported-ice :end-before: #end-supported-ice To install PostgreSQL 9.4: .. literalinclude:: walkthrough/walkthrough_centos7.sh :start-after: #end-supported-ice :end-before: #end-step01 See :download:`requirements.txt` Create an omero system user, and a directory for the OMERO repository: .. literalinclude:: walkthrough/walkthrough_centos7.sh :start-after: #start-step02 :end-before: #end-step02 Create a database user and initialize a new database for OMERO. As postgres who is the admin for a PostgreSQL installation, run: .. literalinclude:: walkthrough/walkthrough_centos7.sh :start-after: #start-step03 :end-before: #end-step03 Installing OMERO.server ----------------------- **The following steps are run as the omero system user.** Download, unzip and configure OMERO. The rest of this walkthrough assumes the OMERO.server is installed into the home directory of the omero system user. Note that this script requires the same environment variables that were set earlier in `settings.env`, so you may need to copy and/or source this file as the omero user. You will need to install the server corresponding to your Ice version. Install ``server-ice36.zip``: .. literalinclude:: walkthrough/walkthrough_centos6_py27_ius.sh :start-after: #start-release-ice36 :end-before: #end-release-ice36 Configure: .. literalinclude:: walkthrough/walkthrough_centos6_py27_ius.sh :start-after: #end-release-ice36 :end-before: #end-step04 Installing a web server ----------------------- To deploy OMERO.web, you can use either Nginx or Apache. Follow the steps to install your chosen web server. Nginx ^^^^^ See also :doc:`install-web/install-nginx`. **The following steps are run as root.** Install Nginx 1.8, copy the Nginx OMERO configuration file into the Nginx configuration directory, and disable the default configuration: .. literalinclude:: walkthrough/walkthrough_centos7.sh :start-after: #start-nginx :end-before: #end-nginx Apache (deprecated) ^^^^^^^^^^^^^^^^^^^ See also :doc:`install-web/install-apache`. As the **omero** system user, configure OMERO.web: .. literalinclude:: walkthrough/walkthrough_centos7.sh :start-after: #start-configure-apache :end-before: #end-configure-apache **The following steps are run as root.** Install Apache 2.4 and copy the Apache OMERO configuration file into the Apache configuration directory: .. literalinclude:: walkthrough/walkthrough_centos7.sh :start-after: #start-apache-install :end-before: #end-apache-install Running OMERO ------------- **The following steps are run as the omero system user.** OMERO should now be set up. To start the server run:: OMERO.server/bin/omero admin start If you deploy with Nginx, to start the OMERO.web client run:: OMERO.server/bin/omero web start The last command is **not** necessary if you deploy with Apache. Nginx or Apache should already be running so you should be able to log in as the OMERO root user by going to http://localhost/ in your web browser. Please read the SELinux_ section below. In addition some example `systemd.service` scripts are available should you wish to start OMERO and OMERO.web automatically: .. literalinclude:: walkthrough/walkthrough_centos7.sh :start-after: #start-step06 :end-before: #end-step06 | :download:`omero-systemd.service ` | :download:`omero-web-systemd.service ` Securing OMERO -------------- **The following steps are run as root.** If multiple users have access to the machine running OMERO you should restrict access to OMERO.server's configuration and runtime directories, and optionally the OMERO data directory: .. literalinclude:: walkthrough/walkthrough_centos7.sh :start-after: #start-step07 :end-before: #end-step07 Regular tasks ------------- **The following steps are run as root.** The default OMERO.web session handler uses temporary files to store sessions which should be deleted at regular intervals, for instance by creating a cron job: .. literalinclude:: walkthrough/walkthrough_centos7.sh :start-after: #start-omeroweb-cron :end-before: #end-omeroweb-cron Copy this script into the appropriate location: .. literalinclude:: walkthrough/walkthrough_centos7.sh :start-after: #start-copy-omeroweb-cron :end-before: #end-copy-omeroweb-cron | :download:`omero-web-cron ` SELinux ------- **The following steps are run as root.** If you are running a system with `SELinux enabled `_ and are unable to access OMERO.web you may need to adjust the security policy: .. literalinclude:: walkthrough/walkthrough_centos7.sh :start-after: #start-selinux :end-before: #end-selinux
