1.1 ! raeburn 1: <h1>Installing LON-CAPA on a minimal SuSE Linux 10.3 System</h1>
! 2: <p>
! 3: This document guides you through the process of setting up a new LON-CAPA
! 4: server running SuSE Linux 10.3 with a minimum of packages installed.
! 5: The computer will be configured solely as a LON-CAPA server and will be
! 6: expected to have no other services running. Your server is expected to have a reasonably fast connection to the internet.
! 7: </p><p>
! 8: More information is available at
! 9: <a href="http://install.lon-capa.org/">http://install.lon-capa.org/</a>.
! 10: </p>
! 11: <h2>Before you begin</h2>
! 12: <p>
! 13: Installing Linux is getting easier and easier. You will be required to log in to the machine and execute some routine Unix commands. Familiarity with the Apache web server, mod_perl, perl, and MySQL are not required to install and run LON-CAPA.
! 14: </p>
! 15: <h2>Installation Overview</h2>
! 16: <p>
! 17: The installation process takes the following steps:
! 18: </p>
! 19: <ol>
! 20: <li> Obtain SuSE 10.3 installation media (DVD, or CD)</li>
! 21: <li> Determine Network Settings</li>
! 22: <li> Install Suse 10.3</li>
! 23: <li> Update your system</li>
! 24: <li> Install LON-CAPA</li>
! 25: <li> Create a Domain Coordinator</li>
! 26: <li> Start/Restart services</li>
! 27: <li> Log in to LON-CAPA</li>
! 28: </ol>
! 29: <h2>Obtain SuSE Linux 10.3</h2>
! 30: <p>
! 31: A SuSE 10.3 iso for burning to DVD can be obtained from the opensuse download site: <a href="http://software.opensuse.org/">http://http://software.opensuse.org/</a>, or from an opensuse mirror site - <a href="http://en.opensuse.org/Mirrors_Released_Version">http://en.opensuse.org/Mirrors_Released_Version</a>. You will also find links there to sites with iso files for burning a Start-CD-Image (a mini.iso) used in a network install, if burning a CD is more convenient for you.
! 32: </p>
! 33: <h2>Determine Network Settings</h2>
! 34: <p>
! 35: You will need to know the following network settings for your installation.
! 36: <b>Note:</b>You must have a static IP address to use LON-CAPA.
! 37: DHCP is <em>not</em> supported.
! 38: </p>
! 39: <ul>
! 40: <li>ip address </li>
! 41: <li>netmask </li>
! 42: <li>hostname </li>
! 43: <li>gateway </li>
! 44: <li>domain name server(s) </li>
! 45: </ul>
! 46: <h2>Minimal SuSE 10.3 Install</h2>
! 47: <p>
! 48: Installing SuSE 10.3 is quite easy if you've installed Linux products
! 49: before. Some documentation is available from
! 50: <a href="http://en.opensuse.org/INSTALL_Local">
! 51: http://en.opensuse.org/INSTALL_Local</a> for installations from DVD and
! 52: <a href="http://en.opensuse.org/INSTALL_Internet">http://en.opensuse.org/INSTALL_Internet</a> for installations via the network, booting from the mini.iso CD.<br /><br />
! 53: Most of the subsequent installation screens are self explanatory.
! 54: There are a few steps that require comment and are dealt with below.
! 55: </p>
! 56: <dl style="list-style:square outside none">
! 57: <dt>Desktop Selection</dt>
! 58: <dd>Click <i>Other</i> and choose <i>Text Mode</i></dd>
! 59: <dt>Software Selection</dt>
! 60: <dd>Choose Expert Mode and for Software enable Base System, Yast Installation Packages and Software Management</dd>
! 61: <dt>Partitioning your Drive</dt>
! 62: <dd>For a LON-CAPA library server (i.e., the main server used
! 63: for permanent storage of course and user data),
! 64: a separate partition is recommended for /home, as this
! 65: simplifies future upgrades of the operating system.
! 66: If you are adding an additional access server to an
! 67: existing LON-CAPA domain, this does not apply as no
! 68: permenent data are stored on an access server.
! 69: As LON-CAPA resource files are stored in the /home directory,
! 70: the majority of the disk space should be allocated here.
! 71: If you have 20 GB of space for SuSE 10.3, /home should
! 72: receive at least 10 to 12 gigs. Since MySQL uses the /var
! 73: filesystem to store its databases you should have as least
! 74: 4 gigs of space available on /var. Be sure to
! 75: include adequate swap space. A minimum is 512 Megs, but you should
! 76: typically have 1 or 2x as much swap space as you do physical RAM.
! 77: </dd>
! 78: </dl>
! 79: <p>Once you system has rebooted, you will use yast to complete the configuration. Change the following settings:
! 80: <dl style="list-style:square outside none">
! 81: <dt>Network Configuration</dt>
! 82: <dd>LON-CAPA will <b>not</b> work with a machine set up to use a dynamic
! 83: IP address. When configuring your network card, you should include host name information (e.g., host name = tmp1, domain = lite.msu.edu), as well as name server. Other settings (ip address, gateway, netmask will have been set when you included them in the boot configuration).
! 84: </dd>
! 85: <dt>Firewall</dt>
! 86: <dd>Enable the firewall, and allow the following services: web services (http and https) and login services (SSH). Use the "Advanced..." option to open the following ports for TCP services: 8080 5663.</dd>
! 87: <dt>Online Update Configuration</dt>
! 88: <dd>It is recommended that you register your server with Novell for future updates during the installation process, and then run the online update.</dd>
! 89: </dt>
! 90: </dl>
! 91: <p>
! 92: After finishing the online update, the system should reboot, and
! 93: proceed to have you create a user account, show you the Release Notes,
! 94: and let you configure any extra hardware, and then finish up the boot
! 95: process. At the prompt login as root.
! 96: </p>
! 97: <h2>Change software sources for your system</h2>
! 98: <p>If you do not already have a SuSE 10.3 installation source at your location, you may want to consider creating one from the iso file for the DVD. Proceed as follows (e.g., for 32 bit):</p>
! 99: <pre>
! 100: mkdir -p suse103/DVD
! 101: mount -o ro,loop SUSE-Linux-10.3-GM-i386-DVD.iso /mnt
! 102: cp -rv /mnt/* suse103/DVD
! 103: umount /mnt
! 104: </pre>
! 105: Next you will use yast to import packages required for LON-CAPA.<br />
! 106: Execute:
! 107: </p>
! 108: <pre>
! 109: yast
! 110: </pre>
! 111: <p>
! 112: Select "Installation Source" and change to point at OSS and non-OSS repositories: (http://download.opensuse.org/distribution/10.3/repo/oss and http://download.opensuse.org/distribution/10.3/repo/non-oss) or alternatively at iternet installation repositories close to your location (see <a href="http://en.opensuse.org/Mirrors_Released_Version">http://en.opensuse.org/Mirrors_Released_Version</a>), or a local institutional source you have built from the SuSE 10.3 DVD, or you may prefer to continue to point at the installation DVD.
! 113: </p>
! 114: <h3>Add an additional installation source</h3>
! 115: <p>Add the LON-CAPA SuSE 10.3 repository as an additional installation source. Once this is done, software installation in yast should then have access to a minimum of three repositories - a YUM source for SuSE updates (established when you run online update from yast), an installation source (for OSS packages included in the standard distribution) and the LON-CAPA repository (for extra packages needed to run LON-CAPA). For the LON-CAPA source you will use:
! 116: <dl style="list-style:square outside none">
! 117: <dd>Media Type</dd>
! 118: <dt>HTTP</dt>
! 119: <dd>Protocol</dd>
! 120: <dt>HTTP</dt>
! 121: <dd>Server Name</dd>
! 122: <dt>install.loncapa.org</dt>
! 123: <dd>Directory on server</dd>
! 124: <dt>suse/10.3/</dt>
! 125: <dd>Authentication</dd>
! 126: <dt>Anonymous</dt>
! 127: </dl>
! 128: After saving this configuration information for the LON-CAPA repository, you will need to import a public LON-CAPA key, before the catalog is read, and the repository is available to you. Quit yast.
! 129: </p>
! 130: <h2>Installing LON-CAPA</h2>
! 131: <h3>Install prerequisites</h3>
! 132: <p> Execute: </p>
! 133: <pre>
! 134: yast -i LONCAPA-prerequisites
! 135: </pre><p>
! 136: This may take a moment due to LON-CAPA's large number of dependencies.
! 137: </p>
! 138: <h3>Retrieve and execute LON-CAPA setup program</h3>
! 139: <p>
! 140: Retrieve the LON-CAPA setup with the following command:
! 141: </p>
! 142: <pre>
! 143: wget http://install.loncapa.org/versions/suse/10.3/suse10.3_install.tar
! 144: </pre>
! 145: <p>
! 146: Extract the archive with the following command:
! 147: </p>
! 148: <pre>
! 149: tar xf suse10.3_install.tar
! 150: </pre>
! 151: <p>
! 152: This creates a directory named <tt>installation</tt>. Change to it and
! 153: execute the setup script with the following commands:
! 154: </p>
! 155: <pre>
! 156: cd installation
! 157: ./install.pl
! 158: </pre>
! 159: <p>
! 160: This script will prompt you for the MySQL root password and will download the latest LON-CAPA release.
! 161: </p>
! 162: <h3>Determine LON-CAPA Settings</h3>
! 163: <p>
! 164: LON-CAPA requires a number of identifying parameters to be set in order
! 165: for it to function at all. Below is a list with descriptions.
! 166: </p>
! 167: <dl>
! 168: <dt>Host Type (library or access)</dt>
! 169: <dd>The server must be designated a 'library' or an 'access' server. In
! 170: general you should have a library server for your instructors to create
! 171: their course content on and run their courses. Students should connect
! 172: to access servers. If you are doing the first install of LON-CAPA at
! 173: your site, or if you are playing with it for your own edification you
! 174: should make your machine a 'library' server.</dd>
! 175: <dt>LON-CAPA domain</dt>
! 176: <dd>Each site or school which installs LON-CAPA needs its own domain.
! 177: Here at MSU we use 'msu'. You should choose something short but
! 178: meaningful. <i>Restriction: One word, no hyphens, underscores, or
! 179: special characters.</i>
! 180: </dd>
! 181: <dt>LON-CAPA host id</dt>
! 182: <dd>Each LON-CAPA server requires a unique internal name. We use names
! 183: such as "msul1" for the first library server. <i>Restriction: One word,
! 184: no hyphens, underscores, or special characters.</i>
! 185: </dd>
! 186: <dt>Host administrator email</dt>
! 187: <dd>The amount of email sent to this address is relatively minimal. Messages
! 188: are sent every time the system starts up, or if the system is in
! 189: serious trouble. On a laptop, make this <tt>root@localhost</tt>.
! 190: </dd>
! 191: </dl>
! 193: <h3>Configuring LON-CAPA</h3>
! 194: <p>
! 195: To configure and install LON-CAPA, execute the following commands:
! 196: </p>
! 197: <pre>
! 198: cd /root/loncapa-N.N (N.N should correspond to a version number like '2.2.2')
! 199: ./UPDATE
! 200: </pre>
! 201: <p>
! 202: You will need to enter the LON-CAPA configuration information you determined
! 203: in the previous section.
! 204: </p>
! 205: <h2>Creating a Domain Coordinator</h2>
! 206: <p>
! 207: You will need at least one user at your site who has the role of
! 208: 'domain coordinator'. This user creates accounts for other users and
! 209: grants them additional privileges. The make_domain_coordinator.pl script
! 210: invoked below requires that you enter the users password. The password will
! 211: show in plaintext as you type it. Feel free to use the "passwd username"
! 212: command to change it later. Replace USERNAME and DOMAIN with an
! 213: appropriate user name and your domain.
! 214: </p>
! 215: <pre>
! 216: cd /root/loncapa-N.N/loncom/build
! 217: perl make_domain_coordinator.pl USERNAME DOMAIN
! 218: (WILL PROMPT FOR PASSWORD HERE)
! 219: </pre>
! 220: <h2>Start/Restart Services</h2>
! 221: <p>
! 222: The LON-CAPA network services take a moment to start. Most misconfigurations
! 223: will be apparent at this step.
! 224: </p>
! 225: <pre>
! 226: /etc/init.d/loncontrol start
! 227: /etc/init.d/apache2 start
! 228: </pre>
! 229: <p>
! 230: If you receive warnings about missing perl modules when starting apache2,
! 231: please make sure you followed the instructions in
! 232: <b>Installing LON-CAPA Dependencies</b>. If you still have errors, please
! 233: contact the LON-CAPA support team.
! 234: </p>
! 235: <h2>Log in to your LON-CAPA Machine</h2>
! 236: <p>
! 237: Point a web browser at your new machine and log in as the domain
! 238: coordinator. Congratulations!
! 239: </p>
! 240: <h2>If things aren't working right</h2>
! 241: <p>
! 242: If you've followed the steps above and the server doesn't start or you think
! 243: there's something wrong, please get in touch with the LON-CAPA support team.
! 244: You can submit a help request using our web form:<br />
! 245: <a href="http://support.loncapa.org/help/">http://support.loncapa.org/help/</a><br />
! 246: If there were errors in installation of the dependency RPMs or during the
! 247: automatic setup, please send us as much information as possible.
! 248: Please let us know if any parts of this document are unclear.
! 249: </p>
