1: <h1>Installing LON-CAPA on a minimal SuSE Linux 11.2 System</h1> 2: <p> 3: This document guides you through the process of setting up a new LON-CAPA 4: server running SuSE Linux 11.2 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: 12: <h2>Before you begin</h2> 13: <p> 14: 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. 15: </p> 16: 17: <h2>Installation Overview</h2> 18: <p> 19: The installation process takes the following steps: 20: </p> 21: <ol> 22: <li><a href="#obt">Obtain SuSE 11.2 installation media (DVD)</a></li> 23: <li><a href="#net">Determine Network Settings</a></li> 24: <li><a href="#lin">Install Suse 11.2</a></li> 25: <li><a href="#upd">Update your system</a></li> 26: <li><a href="#ilc">Install LON-CAPA</a></li> 27: <li><a href="#cdc">Create a Domain Coordinator</a></li> 28: <li><a href="#sts">Start/Restart services</a></li> 29: <li><a href="#log">Log in to LON-CAPA</a></li> 30: </ol> 31: <hr /> 32: 33: <h2>1. <a name="obt">Obtain SuSE Linux 11.2</a></h2> 34: <p> 35: A SuSE 11.2 iso for burning to DVD can be obtained from the opensuse download site: <a href="http://software.opensuse.org/">http://software.opensuse.org/</a>, or from an opensuse mirror site - <a href="http://download.opensuse.org/">http://download.opensuse.org/</a>. You will also find links there to sites with iso files for burning a Start-CD-Image (e.g., openSUSE-11.2-NET-i586.iso for 32 bit) used in a network install, if burning a CD is more convenient for you. 36: </p> 37: 38: <h2>2. <a name="net">Determine Network Settings</a></h2> 39: <p> 40: You will need to know the following network settings for your installation. 41: <b>Note:</b>You must have a static IP address to use LON-CAPA. 42: DHCP is <em>not</em> supported. 43: </p> 44: <ul> 45: <li>ip address </li> 46: <li>netmask </li> 47: <li>hostname </li> 48: <li>gateway </li> 49: <li>domain name server(s) </li> 50: </ul> 51: 52: <h2>3. <a name="lin">Minimal SuSE 11.2 Install</a></h2> 53: <p> 54: Installing SuSE 11.2 is quite easy if you've installed Linux products 55: before. Some documentation is available from the 56: <a href="http://doc.opensuse.org/products/opensuse/openSUSE/opensuse-startup/art.osuse.installquick.html"> 57: Installation Quick Start</a> guide.<br /><br /> 58: Most of the installation screens are self explanatory. 59: There are a few steps that require comment and are dealt with below. 60: </p> 61: <dl style="list-style:square outside none"> 62: <dt>Installation Language</dt> 63: <dd>Use English as your installation language.</dd> 64: <dt>Desktop Selection</dt> 65: <dd>Click <i>Other</i> and choose <i>Text Mode</i></dd> 66: <dt>Software Selection</dt> 67: <dd>Choose Expert Mode and for Software enable Base System, Yast Installation Packages and Software Management</dd> 68: <dt>Partitioning your Drive</dt> 69: <dd>For a LON-CAPA library server (i.e., the main server used 70: for permanent storage of course and user data), 71: a separate partition is recommended for /home, as this 72: simplifies future upgrades of the operating system. 73: If you are adding an additional access server to an 74: existing LON-CAPA domain, this does not apply as no 75: permenent data are stored on an access server. 76: As LON-CAPA resource files are stored in the /home directory, 77: the majority of the disk space should be allocated here. 78: If you have 20 GB of space for SuSE 11.2, /home should 79: receive at least 10 to 12 gigs. Since MySQL uses the /var 80: filesystem to store its databases you should have as least 81: 4 gigs of space available on /var. Be sure to 82: include adequate swap space. A minimum is 512 Megs, but you should 83: typically have 1 or 2x as much swap space as you do physical RAM. 84: </dd> 85: </dl> 86: <p>Once you system has rebooted, you will use yast to complete the configuration. Change the following settings: 87: <dl style="list-style:square outside none"> 88: <dt>Network Configuration</dt> 89: <dd>LON-CAPA will <b>not</b> work with a machine set up to use a dynamic 90: 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). 91: </dd> 92: <dt>Firewall</dt> 93: <dd>Enable the firewall, and allow login services (SSH).</dd> 94: </dl> 95: <p> 96: After finishing the online update, the system should reboot, and 97: proceed to have you create a user account, show you the Release Notes, 98: and let you configure any extra hardware, and then finish up the boot 99: process. At the prompt login as root. 100: </p> 101: 102: <h2>4. <a name="upd">Change software sources for your system</a></h2> 103: Next you will use yast to import packages required for LON-CAPA.<br /> 104: Execute: 105: </p> 106: <pre> 107: yast 108: </pre> 109: <p> 110: Select "Installation Source" and change to point at OSS and non-OSS repositories: (http://download.opensuse.org/distribution/11.2/repo/oss and http://download.opensuse.org/distribution/11.2/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 11.2 DVD, or you may prefer to continue to point at the installation DVD. 111: </p> 112: <h3>Add additional installation sources</h3> 113: <p>Add the LON-CAPA SuSE 11.2 repository as an additional installation source.</p> 114: <p>Use zypper to add the LON-CAPA SuSE 11.2 repository and two additional repositiories provide by openSuSE - one for the R statistics package (the R-patched repo), and one for the Maxima computer algebra system (the science repo). Use the following commands to add them. 115: <pre> 116: zypper ar -f 'http://install.loncapa.org/suse/11.2' LON-CAPA 117: zypper ar -f 'http://download.opensuse.org/repositories/devel:languages:R:patched/openSUSE_11.2' R-patched 118: zypper ar -f 'http://download.opensuse.org/repositories/science/openSUSE_11.2' science 119: </pre> 120: You will need to confirm that you wish to trust the key used to sign the packages in the LON-CAPA SuSE 11.2 repository. 121: </p> 122: <h2>5. <a name="ilc">Installing LON-CAPA</a></h2> 123: <h3>Install prerequisites</h3> 124: <p> Execute: </p> 125: <pre> 126: yast -i LONCAPA-prerequisites 127: </pre><p> 128: This may take some minutes due to LON-CAPA's large number of dependencies. 129: </p> 130: <h3>Configure firewall settings for Apache</h3> 131: <p>After Apache has been installed use yast to configure the Firewall to open port 80 for http (and port 443 for https, if you plan to use Apache with SSL). 132: <dl style="list-style:square outside none"> 133: <dt>Firewall</dt> 134: <dd>Allow the following services: web services (http and https).</dd> 135: </dl> 136: </p> 137: <h3>Retrieve and execute LON-CAPA setup program</h3> 138: <p> 139: Retrieve the LON-CAPA setup with the following command: 140: </p> 141: <pre> 142: wget http://install.loncapa.org/linux/install.tar 143: </pre> 144: <p> 145: Extract the archive with the following command: 146: </p> 147: <pre> 148: tar xf install.tar 149: </pre> 150: <p> 151: This creates a directory named <tt>installation</tt>. Change to it and 152: execute the setup script with the following commands: 153: </p> 154: <pre> 155: cd installation 156: ./install.pl 157: </pre> 158: <p> 159: The script is used to prepare a Linux system to run LON-CAPA, and can also be 160: used to check the configuration of a system on which LON-CAPA has already been installed. Typically, though, you will run this script only once, when you first install LON-CAPA. 161: </p> 162: <p> 163: The script will analyze your system to determine which actions are recommended. The script will then prompt you to choose the actions you would like taken. 164: Once a choice has been entered for all nine possible actions, required changes will be made. 165: </p> 166: <p>The possible actions are: 167: <ul> 168: <li>Create the www user/group</li> 169: <li>Install the package LON-CAPA uses to authenticate users.</li> 170: <li>Set-up the MySQL database</li> 171: <li>Set-up MySQL permissions</li> 172: <li>Configure Apache web server</li> 173: <li>Configure start-up of services</li> 174: <li>Check firewall settings</li> 175: <li>Stop services not used by LON-CAPA,<br /> 176: e.g., services for a print server: cups daemon</li> 177: <li>Download LON-CAPA source code in readiness for installation</li> 178: </ul> 179: </p> 180: <h3>Determine LON-CAPA Settings</h3> 181: <p> 182: LON-CAPA requires a number of identifying parameters to be set in order 183: for it to function at all. Below is a list with descriptions. 184: </p> 185: <dl> 186: <dt>Host Type (library or access)</dt> 187: <dd>The server must be designated a 'library' or an 'access' server. In 188: general you should have a library server for your instructors to create 189: their course content on and run their courses. Students should connect 190: to access servers. If you are doing the first install of LON-CAPA at 191: your site, or if you are playing with it for your own edification you 192: should make your machine a 'library' server.</dd> 193: <dt>LON-CAPA domain</dt> 194: <dd>Each site or school which installs LON-CAPA needs its own domain. 195: Here at MSU we use 'msu'. You should choose something short but 196: meaningful. <i>Restriction: One word, no hyphens, underscores, or 197: special characters.</i> 198: </dd> 199: <dt>LON-CAPA host id</dt> 200: <dd>Each LON-CAPA server requires a unique internal name. We use names 201: such as "msul1" for the first library server. <i>Restriction: One word, 202: no hyphens, underscores, or special characters.</i> 203: </dd> 204: <dt>Host administrator email</dt> 205: <dd>The amount of email sent to this address is relatively minimal. Messages 206: are sent every time the system starts up, or if the system is in 207: serious trouble. On a laptop, make this <tt>root@localhost</tt>. 208: </dd> 209: </dl> 210: 211: <h3>Configuring LON-CAPA</h3> 212: <p> 213: To configure and install LON-CAPA, execute the following commands: 214: </p> 215: <pre> 216: cd /root/loncapa-X.Y.Z (X.Y.Z should correspond to a version number like '2.10.0') 217: ./UPDATE 218: </pre> 219: <p> 220: You will need to enter the LON-CAPA configuration information you determined 221: in the previous section. 222: </p> 223: 224: <h2>6. <a name="cdc">Creating a Domain Coordinator</a></h2> 225: <p> 226: You will need at least one user at your site who has the role of 227: 'domain coordinator'. This user creates accounts for other users and 228: grants them additional privileges. The make_domain_coordinator.pl script 229: invoked below requires that you enter the user's password. 230: Feel free to use the "passwd username" command to change it later. 231: Replace USERNAME and DOMAIN with an appropriate user name and your domain. 232: </p> 233: <pre> 234: cd /root/loncapa-X.Y.Z/loncom/build 235: perl make_domain_coordinator.pl USERNAME DOMAIN 236: </pre> 237: 238: <h2>7. <a name="sts">Start/Restart Services</a></h2> 239: <p> 240: The LON-CAPA network services take a moment to start.
