Installing Globus ToolKit 2.4:  Installing Globus ToolKit 2.4 Dr. Itzhak Ben-Akiva (TAU) David Front (WI) Agenda:  Agenda Globus Overview Distributions available Packaging tools available Installation overview Installation step-by-step Obtaining Certificates Testing the Installation Configuring the server daemons Last words Globus Overview:  Globus Overview The Globus Project provides software tools that make it easier to build computational grids and grid-based applications. These tools are collectively called the Globus Toolkit(tm). The composition of the Globus Toolkit can be pictured as three pillars. Each pillar represents a primary component of the Globus Toolkit and makes use of a common foundation of security. Resource Management Information Services Data Management Globus Overview – cont.:  Globus Overview – cont. GRAM implements a resource management protocol. MDS implements an information services protocol. GridFTP implements a data transfer protocol. They all use the GSI security protocol at the connection layer. Note: A detailed explanation of each component was given by David Front What is available?:  What is available? Globus is available in two different format for installation: Binary distribution Build a Grid environment develop Grid-enabled Applications Use Grid Tools Source distribution Change Globus ToolKit Code Debug GTK code at source level Install GTK on a platform fr which precompiled binaries are not available What bundles are available?:  What bundles are available? Globus is available in three different bundles: Client: constains the necessary pieces to be a consumer of Grid services Server: constains the necessary pieces to install the Grid servers (GridFTP, MDS, GateKeeper, etc) SDK: contains the libraries and headers required to compile and link your application to Globus. If you developing against Globus, this package is certainly your choise. You can download the bundles from http://globus.org/gt2.4/download.html Installation Overview:  Installation Overview The installation will follow these steps: Create a user named 'globus' (optional, but recommended) Create a location to install Globus Install GPT or VDT Use GPT to install the source or binary bundles Obtaining Certificates Creating grid-mapfile Configure the installation Testing your installation Step 1: Create a user named “globus”:  Step 1: Create a user named 'globus' It is recommended to create a user named 'globus' and execute the installation as this user. Exception to the above will happen when you have to set up server services. Step 2: Create location to install:  Step 2: Create location to install Create two directories, one where you want to install GTK and the other to install GPT. They should be owned by user 'globus'. Set up the Globus environment variables: {csh} setenv GLOBUS_LOCATION andlt;globus_install_dirandgt; {bash} export GLOBUS_LOCATION=andlt;globus_install_dirandgt; Set up GPT environment variables: {csh} setenv GPT_LOCATION andlt;gpt_install_dirandgt; {bash} export GPT_LOCATION=andlt;gpt_install_dirandgt; Step 3: Installing GPT:  Step 3: Installing GPT What is GPT (Grid Packaging Tool)? - GPT is a multi-platform packaging system used to deploy Grid middleware, developed by NCSA. GPT was designed to re-implement the deployment requirements of Globus plus shared libraries. - Most of Globus is libraries. - Globus has deployment requirements for client tools, service daemons, and development/build environments. - Globus wants to release individual components separately. - Globus wants to add outside software (ie. openssl, openldap) to these deployments. - Globus wants to work on multiple platforms. More information can be found on http://www.ncsa.uiuc.edu/Divisions/ACES/GPT/ Step 3a: Installating GPT – cont.:  Step 3a: Installating GPT – cont. GPT requires Perl 5.005 or greater and GNU tar and GNU make. In the directory where you downloaded the tarballs, do the following: 1. tar -xzvf gpt-2.2.9-src.tar.gz 2. cd gpt-2.2.9 3. ./build_gpt You are done! Installing Globus and Condor w/ VDT:  Installing Globus and Condor w/ VDT Another option is to install Globus and Condor together through the packaging tool named VDT. For a detailed installation instruction on VDT, refer to http://www.lsc-group.phys.uwm.edu/vdt/installation.html Step 4: Binary Bundle Installation:  Step 4: Binary Bundle Installation To install the binary bundle on Intel i686 platform, run the following commands: $GPT_LOCATION/sbin/gpt-install \ globus-all-2.4.0-i686-pc-linux-gnu-bin.tar.gz {csh} source $GLOBUS_LOCATION/etc/globus-user-env.csh or {sh} . $GLOBUS_LOCATION/etc/globus-user-env.sh $GPT_LOCATION/sbin/gpt-postinstall If you install any sdk bundle, you have to run the following command: $GPT_LOCATION/sbin/gpt-build andlt;flavorandgt; -nosrc Note: The binary bundles contained on the download page use gcc32dbg as the build flavor for Linux. Step 4a: Source Bundle Installation:  Step 4a: Source Bundle Installation You have to run the following command for each source bundle you downloaded: $GPT_LOCATION/sbin/gpt-build andlt;bundleandgt; andlt;flavorsandgt; \ -logdir=andlt;log directoryandgt; List of Source Bundles:  List of Source Bundles globus-data-management-client-2.4.0-src_bundle.tar.gz gcc32dbg globus-data-management-sdk-2.4.0-src_bundle.tar.gz gcc32dbg globus-data-management-server-2.4.0-src_bundle.tar.gz gcc32dbg globus-information-services-client-2.4.0-src_bundle.tar.gz gcc32dbgpthr globus-information-services-sdk-2.4.0-src_bundle.tar.gz gcc32dbgpthr globus-information-services-server-2.4.0-src_bundle.tar.gz gcc32dbg globus-resource-management-client-2.4.0-src_bundle.tar.gz gcc32dbg globus-resource-management-sdk-2.4.0-src_bundle.tar.gz gcc32dbg globus-resource-management-server-2.4.0-src_bundle.tar.gz gcc32dbg globus-resource-management-server-2.4.0-src_bundle.tar.gz gcc32dbg Step 4b: Source bundle installation:  Step 4b: Source bundle installation You need to source the following file before we finish our install. To do so, run the following command depending on your shell: {csh} source $GLOBUS_LOCATION/etc/globus-user-env.csh {sh} . $GLOBUS_LOCATION/etc/globus-user-env.sh Lastly, run the following commands: $GPT_LOCATION/sbin/gpt-postinstall Installation Structure:  Installation Structure $GLOBUS_LOCATION programs libraries include etc setup lib libexec gcc32 headers gcc32pthr headers packaging metadata sbin Step 5: Configuring your installation:  Step 5: Configuring your installation Now, you have to become root to run the command to set up GSI. Run $GLOBUS_LOCATION/setup/globus/setup-gsi This will install GSI files into /etc/grid-security If you do not have root on the system, run $GLOBUS_LOCATION/setup/globus/setup-gsi -nonroot to install the security information into $GLOBUS_LOCATION/etc instead of /etc/grid-security. The -nonroot option is aimed at client-side installs. Obtaining Certificates:  Obtaining Certificates Security is at the heart of Globus. As such, you will not be able to test Globus until you get a certificate for yourself. Currently, Globus has three diferent types of certificates: - User Certificate - Host Certificate - LDAP Certificate I will describe here how to obtain a Globus Certificate. However, be aware that there are CA, which will involve the configuration step of adding trusted CA into Globus. Obtaining Globus Certificates:  Obtaining Globus Certificates Make sure you are running as your normal user account. Run grid-cert-request grid-cert-request will ask for a password to protect your key, and give you a set of instructions for how to mail your request to the CA. Three files will be generated into ~/.globus: usercert_request.pem, userkey.pem and usercert.pem When you receive your certificate from Globus, place it into ~/.globus directory. Create the grid-mapfile:  Create the grid-mapfile Once you get your user certificate, you must create the grid-mapfile, which must contain the pair subject name ans user account of all user allowed to access your Grid services. Run grid-proxy-init to create a user proxy and afterwards run: grid-proxy-info -subject to get your subject name. Become root. Create a file named: /etc/grid-security/grid-mapfile and add an entry like this: '/O=Grid/O=Globus/OU=tau.ac.il/CN=Itzhak Ben-Akiva' benakiva Obtaining Host Certificate:  Obtaining Host Certificate Very important: The certificate must be for a machine that has a consistent name in the DNS; it should not run on a machine where a different name could be assigned to it. Become root and run the following command: - grid-cert-request -service host -host andlt;your-hostname-hereandgt; Then, using your regular, user mail agent, send an email to ca@globus.org and copy and paste the contents of the request into it. grid-cert-request will output the location of the request. Please do not include this file as an attachment. Do not send this mail from the root account. Obtaining LDAP Certificates:  Obtaining LDAP Certificates Become root and run the following command: - grid-cert-request -service ldap -host andlt;FQDNandgt; Then, using your regular, user mail agent, send an email to ca@globus.org and copy and paste the contents of the request into it. grid-cert-request will output the location of the request. Please do not include this file as an attachment. When you receive the certificate, save the entire email to /etc/grid-security/ldap/ldapcert.pem and to /etc/grid-security/ldap/ldapkey.pem. Testing your installation: GRAM:  Testing your installation: GRAM As your normal user run the following command to create a proxy: grid-proxy-init -debug -verify Start your personal gatekeeper by running: - globus-personal-gatekeeper -start This will generate a contact string like: alzt1.tau.ac.il:39705:/O=Grid/O=Globus/OU=tau.ac.il/CN=benakiva Run globus-job-run andlt;contactandgt; /bin/date. Substitute the contact string by the one generated by globus-personal-gatekeeper Top the personal gatekeeper and destroy the proxy by running: - globus-personal-gatekeeper -killall - grid-proxy-destroy Testing your Installation: MDS:  Testing your Installation: MDS By default, MDS allows anonymous access, which we will use for the purpose of this test. For information on how to configure MDS for non-anonymous access, refer to http://globus.org/gt2.4/admin/guide-configure.html#mds Start MDS by running the command: GLOBUS_LOCATION/sbin/globus-mds start Send a test query on a local host by running the command: GLOBUS_LOCATION/bin/grid-info-search -anonymous -L Testing your Installation: GridFTP:  Testing your Installation: GridFTP First, create a user proxy: - grid-proxy-init Create a file named ~/.gridmap and add an entry with your subject, like: '/O=Grid/O=Globus/OU=tau.ac.il/CN=Itzhak Ben-Akiva' your-username Start the GridFTP server: - $GLOBUS_LOCATION/sbin/in.ftpd -S -p 5678 -S leaves the daemon in the background -p specify the port Create a file name /tmp/file1 and run the followinf command: - globus-url-copy -s '`grid-cert-info -subject`' \ gsiftp://localhost:5678/tmp/file1 file:///tmp/file2 Check to make sure that /tmp/file2 now exists. Services Startup:  Services Startup I showed before how to start your services manually. Howerver, you can configure them to start automatically with your system. We will learn how to configure the startup of the following services: - GRAM - MDS - GridFTP Starting GRAM:  Starting GRAM All the following modifications must be done as root. In the file /etc/services add a new services: gsigatekeeper 2119/tcp # Globus Gatekeeper If you're running inetd add the following entry all in one line into the file /etc/inetd.conf: gsigatekeeper stream tcp nowait root /usr/bin/env env LD_LIBRARY_PATH=GLOBUS_LOCATION/lib GLOBUS_LOCATION/sbin/globus-gatekeeper -conf GLOBUS_LOCATION/etc/globus-gatekeeper.conf Be sure to replace GLOBUS_LOCATION below with the actual value of $GLOBUS_LOCATION in your environment. Or, if you're running xinetd: Configuring xinetd:  Configuring xinetd Add a file named 'globus-gatekeeper' to the /etc/xinetd.d/ directory with the following content: service gatekeeper { socket_type = stream protocol = tcp wait = no user = root env = LD_LIBRARY_PATH=GLOBUS_LOCATION/lib server = GLOBUS_LOCATION/sbin/globus-gatekeeper server_args = -conf GLOBUS_LOCATION/etc/globus-gatekeeper.conf disable = no } Restart the service: killall -HUP inetd or /etc/rc.d/init.d/xinetd restart Starting MDS:  Starting MDS Start MDS 2.2 with the following command: GLOBUS_LOCATION/sbin/globus-mds start Create a script calling this command and put it into /etc/rc.d/init.d/mds and a call to that script made in the appropriate /etc/rc.d/rc?.d (where ? is the default runlevel of your system, as specified in /etc/inittab) Starting GridFTP:  Starting GridFTP All the following modifications must be done as root. Add an entry to /etc/services reading: gsiftp 2811/tcp # GridFTP Service For inetd, add the following entry, all on one line, to /etc/inetd.conf. Be sure to replace GLOBUS_LOCATION below with the actual value of $GLOBUS_LOCATION in your environment: gsiftp stream tcp nowait root /usr/bin/env env LD_LIBRARY_PATH=GLOBUS_LOCATION/lib GLOBUS_LOCATION/sbin/in.ftpd -l -a -G GLOBUS_LOCATION Restarts inetd by running killall -HUP inetd Configuring xinetd for GridFTP:  Configuring xinetd for GridFTP Add a file named 'grid-ftp' to the /etc/xinetd.d/ directory with the following content: service gsiftp { socket_type = stream protocol = tcp wait = no user = root env = LD_LIBRARY_PATH=GLOBUS_LOCATION/lib server = GLOBUS_LOCATION/sbin/in.ftpd server_args = -l -a -G GLOBUS_LOCATION log_on_success += DURATION USERID log_on_failure += USERID nice = 10 disable = no } Restart the service by running /etc/rc.d/init.d/xinetd restart Advanced Configuration:  Advanced Configuration On how to configure the server daemons beyond the default configuration, I will direct you to the following web page:http://globus.org/gt2.4/admin/guide-configure.html By this time you're done with the configuration Last words:  Last words Globus is under constant development. Bugs fixes, security and enhancements are released frequently. As an advice, check frequently the advisory page: http://www-unix.globus.org/toolkit/2.4/advisories/
