Update directions on building local repository from SLES10 iso files.

1: <h1>Installing LON-CAPA on a minimal SuSE Linux Enterprise Server (SLES) 10</h1> 2: <p> 3: This document guides you through the process of setting up a new LON-CAPA 4: server running SuSE Linux Enterprise Server 10 (SLES 10) 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 7: a reasonably fast connection to the internet. 8: </p><p> 9: More information is available at 10: <a href="http://install.lon-capa.org/">http://install.lon-capa.org/</a>. 11: </p> 12: 13: <h2>Before you begin</h2> 14: <p> 15: Installing Linux is getting easier and easier. 16: You will be required to log in to the machine and execute 17: some routine Unix commands. Familiarity with the Apache web server, mod_perl, 18: perl, and MySQL are not required to install and run LON-CAPA. 19: </p> 20: 21: <h2>Installation Overview</h2> 22: <p> 23: The installation process takes the following steps: 24: </p> 25: <ol> 26: <li> Obtain SLES 10 installation media</li> 27: <li> Determine Network Settings</li> 28: <li> Install SLES 10</li> 29: <li> Update your system </li> 30: <li> Install LON-CAPA </li> 31: <li> Create a Domain Coordinator </li> 32: <li> Start/Restart services </li> 33: <li> Log in to LON-CAPA </li> 34: </ol> 35: 36: <h2>Obtain SuSE Linux Enterprise Server 10</h2> 37: <p> 38: SuSE ISO files can be obtained from the Novell site: <a href="http://www.novell.com/products/server/">http://www.novell.com/products/server/</a>. 39: </p> 40: 41: <h2>Determine Network Settings</h2> 42: <p> 43: You will need to know the following network settings for your installation. 44: <b>Note:</b>You must have a static IP address to use LON-CAPA. 45: DHCP is <em>not</em> supported. 46: </p> 47: <ul> 48: <li>ip address </li> 49: <li>netmask </li> 50: <li>hostname </li> 51: <li>gateway </li> 52: <li>domain name server(s) </li> 53: </ul> 54: 55: <h2>Minimal SLES 10 Install</h2> 56: <p> 57: Installing SuSE Linux Enterprise Server is quite easy if you've installed Linux products 58: before. Some documentation is available from 59: <a href="http://www.novell.com/documentation/sles10/"> 60: http://www.novell.com/documentation/sles10/</a>.<br /><br /> 61: Most of the subsequent installation screens are self explanatory. 62: There are a few steps that require comment and are dealt with below. 63: </p> 64: <dl style="list-style:square outside none"> 65: <dt>Partitioning your Drive</dt> 66: <dd>For a LON-CAPA library server (i.e., the main server used 67: for permanent storage of course and user data), 68: a separate partition is recommended for /home, as this 69: simplifies future upgrades of the operating system. 70: If you are adding an additional access server to an 71: existing LON-CAPA domain, this does not apply as no 72: permanent data are stored on an access server. 73: As LON-CAPA resource files are stored in the /home directory, 74: the majority of the disk space should be allocated here. 75: If you have 20 GB of space for SLES10, /home should 76: receive at least 10 to 12 gigs. Since MySQL uses the /var 77: filesystem to store its databases you should have as least 78: 4 gigs of space available on /var. Be sure to 79: include adequate swap space. A minimum is 512 Megs, but you should 80: typically have 1 or 2x as much swap space as you do physical RAM. 81: </dd> 82: <dt>Software Selection</dt> 83: <dd> 84: Installation of the minimum set of packages is recommended. This will involve unchecking all checkboxes except for the base SuSE installation.</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 you static IP address, netmask, host name information (e.g., host name = tmp1, domain = lite.msu.edu), as well as name servers and gateway. 91: </dd> 92: <dt>Online update</dt> 93: <dd>Indicate "Yes" when prompted to "run online update now?"</dd> 94: </dt> 95: </dl> 96: <p> 97: Finish installing your server, read the "readme", reboot and log in as root. 98: </p> 99: <h2>Configure Firewall Settings</h2> 100: <p>After reboot you should start yast, and select Security and Users -> Firewall. At step 2 include the following services: HTTP, HTTP with SSL, and Secure Shell. Use the "Expert..." option to add additional TCP services on ports 5663 and 8080. 101: </p> 102: <h2>Change software sources for your system</h2> 103: <p> 104: You will use yast to import packages required for LON-CAPA.<br /> 105: Execute: 106: </p> 107: <pre> 108: yast 109: </pre> 110: <p> 111: Select "Change Source of Installation". The media you used to install SLES10 will be listed as an installation source. If you do not already have a SLES10 installation source at your location, you may want to consider creating one from the 4 iso files for CDs 1 - 4, to avoid the need to flip CDs during LON-CAPA installation. Proceed as follows (e.g., for 32 bit):</p> 112: <pre> 113: mkdir -p sles10/CD1 114: mount -o ro,loop SLES-10-x86-CD1.iso /mnt 115: cp -rv /mnt/* sles10/CD1 116: umount /mnt 117: </pre> 118: <p> 119: Repeat those steps with CD2, CD3 and CD4.</p> 120: <h3>Add an additional installation source</h3> 121: <p>Add the LON-CAPA SLES 10 repository as an additional installation source, so software installation in yast will have access to at least two repositories - a SuSE/Novell source (for packages included for the standard distribution) and the LON-CAPA repository (for extra packages needed to run LON-CAPA). For the LON-CAPA source you will use: 122: <dl style="list-style:square outside none"> 123: <dd>Protocol</dd> 124: <dt>HTTP</dt> 125: <dd>Server Name</dd> 126: <dt>install.loncapa.org</dt> 127: <dd>Directory on server</dd> 128: <dt>suse/sles10/</dt> 129: <dd>Authentication</dd> 130: <dt>Anonymous</dt> 131: </dl> 132: After saving this configuration information for the LON-CAPA repository, quit yast. 133: </p> 134: <h3>Install prerequisites</h3> 135: <p> Execute: </p> 136: <pre> 137: yast -i LONCAPA-prerequisites 138: </pre><p> 139: This may take a moment due to LON-CAPA's large number of dependencies. 140: </p> 141: <h3>Retrieve and execute LON-CAPA setup program</h3> 142: <p> 143: Retrieve the LON-CAPA setup with one of the following commands: 144: </p> 145: <pre> 146: wget http://install.loncapa.org/versions/suse/sles10/sles10_install.tar 147: </pre> 148: <p> 149: Extract the archive with the following command: 150: </p> 151: <pre> 152: tar xf sles10_install.tar 153: </pre> 154: <p> 155: This creates a directory named <tt>installation</tt>. Change to it and 156: execute the setup script with the following commands: 157: </p> 158: <pre> 159: cd installation 160: ./install.pl 161: </pre> 162: <p> 163: This script will prompt you for the MySQL root password and will download the latest LON-CAPA release. 164: </p> 165: <h3>Determine LON-CAPA Settings</h3> 166: <p> 167: LON-CAPA requires a number of identifying parameters to be set in order 168: for it to function at all. Below is a list with descriptions. 169: </p> 170: <dl> 171: <dt>Host Type (library or access)</dt> 172: <dd>The server must be designated a 'library' or an 'access' server. In 173: general you should have a library server for your instructors to create 174: their course content on and run their courses. Students should connect 175: to access servers. If you are doing the first install of LON-CAPA at 176: your site, or if you are playing with it for your own edification you 177: should make your machine a 'library' server.</dd> 178: <dt>LON-CAPA domain</dt> 179: <dd>Each site or school which installs LON-CAPA needs its own domain. 180: Here at MSU we use 'msu'. You should choose something short but 181: meaningful. <i>Restriction: One word, no hyphens, underscores, or 182: special characters.</i> 183: </dd> 184: <dt>LON-CAPA host id</dt> 185: <dd>Each LON-CAPA server requires a unique internal name. We use names 186: such as "msul1" for the first library server. <i>Restriction: One word, 187: no hyphens, underscores, or special characters.</i> 188: </dd> 189: <dt>Host administrator email</dt> 190: <dd>The amount of email sent to this address is relatively minimal. Messages 191: are sent every time the system starts up, or if the system is in 192: serious trouble. On a laptop, make this <tt>root@localhost</tt>. 193: </dd> 194: </dl> 195: 196: <h3>Configuring LON-CAPA</h3> 197: <p> 198: To configure and install LON-CAPA, execute the following commands: 199: </p> 200: <pre> 201: cd /root/loncapa-N.N.N (N.N.N should correspond to a version number like '2.2.2') 202: ./UPDATE 203: </pre> 204: <p> 205: You will need to enter the LON-CAPA configuration information you determined 206: in the previous section. 207: </p> 208: <p>After installing LON-CAPA, and taking any actions included in the WARNINGS file created during installation, it is recommended that you set loncontrol to start automatically on boot, by executing the following command:</p> 209: <pre> 210: /sbin/chkconfig --level 345 loncontrol on 211: </pre> 212: <h2>Creating a Domain Coordinator</h2> 213: <p> 214: You will need at least one user at your site who has the role of 215: 'domain coordinator'. This user creates accounts for other users and 216: grants them additional privileges. The make_domain_coordinator.pl script 217: invoked below requires that you enter the users password. The password will 218: show in plaintext as you type it. Feel free to use the "passwd username" 219: command to change it later. Replace USERNAME and DOMAIN with an 220: appropriate user name and your domain. 221: </p> 222: <pre> 223: cd /root/loncapa-N.N/loncom/build 224: perl make_domain_coordinator.pl USERNAME DOMAIN 225: (WILL PROMPT FOR PASSWORD HERE) 226: </pre> 227: <h2>Start/Restart Services</h2> 228: <p> 229: The LON-CAPA network services take a moment to start. Most misconfigurations 230: will be apparent at this step. 231: </p> 232: <pre> 233: /etc/init.d/loncontrol start 234: /etc/init.d/apache2 start 235: </pre> 236: <p> 237: If you receive warnings when starting the httpd about missing perl modules, 238: please make sure you followed the instructions in 239: <b>Installing LON-CAPA Dependencies</b>. If you still have errors, please 240: contact the LON-CAPA support team. 241: </p> 242: <h2>Log in to your LON-CAPA Machine</h2> 243: <p> 244: Point a web browser at your new machine and log in as the domain 245: coordinator. Congratulations! 246: </p> 247: <h2>If things aren't working right</h2> 248: <p> 249: If you've followed the steps above and the server doesn't start or you think 250: there's something wrong, please get in touch with the LON-CAPA support team. 251: You can submit a help request using our web form:<br /> 252: <a href="http://support.loncapa.org/help/">http://support.loncapa.org/help/</a><br /> 253: If there were errors in installation of the dependency RPMs or during the 254: automatic setup, please send us as much information as possible. 255: If some part of this document is unclear please let us know. 256: </p>
