! 13: <h1>Installing LON-CAPA on a Fedora Linux System</h1>
! 14: <p>
! 15: This document guides you through the process of setting up a new LON-CAPA
! 16: server running Fedora Linux. The computer will be configured solely as
! 17: a LON-CAPA server and will be expected to have no other services running
! 18: on it.
! 19: </p><p>
! 20: More information is available at <a href="http://install.lon-capa.org/">
! 21: http://install.lon-capa.org/</a>.
! 22: </p>
! 23:
! 24: <h2>Before you begin</h2>
! 25: <p>
! 26: Installing Linux is getting easier and easier. However, it is still a
! 27: non-trivial undertaking and experience with Red Hat Linux will make this
! 28: process easier. You will be required to log in to the machine and execute
! 29: some routine Unix commands. Some familiarity with Linux is assumed.
! 30: Familiarity with the Apache web server, mod_perl, perl, and MySQL are not
! 31: required to install and run LON-CAPA.
! 32: </p>
! 33:
! 34: <h2>Installation Overview</h2>
! 35: <p>
! 36: The installation process takes the following steps:
! 37: </p>
! 38: <ol>
! 39: <li> Obtain Fedora Linux </li>
! 40: <li> Determine Network Settings</li>
! 41: <li> Install Fedora </li>
! 42: <li> Install LON-CAPA Dependencies </li>
! 43: <li> Determine your LON-CAPA Settings </li>
! 44: <li> Install LON-CAPA </li>
! 45: <li> Configure LON-CAPA </li>
! 46: <li> Pick a hosts.tab file </li>
! 47: <li> Create a Domain Coordinator </li>
! 48: <li> Start/Restart services </li>
! 49: <li> Log in to LON-CAPA </li>
! 50: </ol>
! 51:
! 52: <h2>Obtain Fedora Linux</h2>
! 53: <p>
! 54: Fedora linux ISO files can be obtained from the projects main site,
! 55: <a href="http://fedora.redhat.com/">http://fedora.redhat.com/</a>.
! 56: </p>
! 57:
! 58: <h2>Determine Network Settings</h2>
! 59: <p>
! 60: You will need to know the following network settings for your installation.
! 61: <b>Note:</b>You must have a static IP address to use LON-CAPA.
! 62: DHCP is <em>not</em> supported.
! 63: </p>
! 64: <ul>
! 65: <li>ip address </li>
! 66: <li>netmask </li>
! 67: <li>hostname </li>
! 68: <li>gateway </li>
! 69: <li>domain name server(s) </li>
! 70: </ul>
! 71:
! 72: <h2>Gather needed information</h2>
! 73:
! 74:
! 75:
! 76: <h2>Install Fedora</h2>
! 77: <p>
! 78: Installing Fedora is quite easy if you've installed any of the Red Hat products
! 79: before. Some documentation is available from
! 80: <a href="http://fedora.redhat.com/projects/anaconda-installer/">
! 81: http://fedora.redhat.com/projects/anaconda-installer/</a>.
! 82: There are a few sections that require comment.
! 83: </p>
! 84: <dl style="list-style:square outside none">
! 85: <dt>Installation Type</dt>
! 86: <dd>You should do a "Server" install. We do not recommend
! 87: trying to install LON-CAPA with a different installation type.</dd>
! 88: <dt>Partitioning your Drive</dt>
! 89: <dd>You may want to use the automatic partitioning feature of the installer,
! 90: however you should review the results and be prepared to modify them.
! 91: LON-CAPA resource files are stored in the /home directory, so the
! 92: lion's share of the drive should be allocated here. If you have 20 GB
! 93: of space for Fedora, /home should receive 16 gigs. Be sure to
! 94: include adequate swap space. A minimum is 512 Megs, but you should
! 95: typically have 1 or 2x as much swap space as you do physical RAM.</dd>
! 96: <dt>Network Configuration</dt>
! 97: <dd>LON-CAPA will <b>not</b> work with a machine set up to use a dynamic
! 98: IP address. When configuring your network card, be sure to unselect
! 99: the DHCP option and enter in your network information.</dd>
! 100: <dt>Firewall Configuration</dt>
! 101: <dd>The firewall should be customized to allow incoming ssh and www.
! 102: Additional ports used by LON-CAPA are 5663 and 8080.
! 103: Enter these in the entry box as <nobr>"5663:tcp, 8080:tcp"</nobr>.</dd>
! 104: <dt>Package Group Selection</dt>
! 105: <dd>
! 106: <b>Do not</b> install a web server. It is intentially omitted from
! 107: this list. Installing packages not listed below is not recommended.
! 108: If you install packages not listed below you should expect difficulties
! 109: when installing the LON-CAPA dependencies.
! 110: <ul>
! 111: <li>Editors</li>
! 112: <li>Text Based Internet</li>
! 113: <li>Authoring and Publishing</li>
! 114: <li>Development Tools
! 115: <li>Administration Tools
! 116: <li>Printing Support
! 117: </ul>
! 118: </dd>
! 119: </dl>
! 120: <p>
! 121: Finish installing your server, reboot it, and log in as root.
! 122: </p>
! 123:
! 124: <h2>Retrieving the LON-CAPA Installation Archive</h2>
! 125: <p>
! 126: Execute the following command:
! 127: </p>
! 128: <pre>
! 129: wget http://install.loncapa.org/versions/fedora/fedora_install.tar
! 130: </pre>
! 131: <p>
! 132: This will retrieve from the LON-CAPA website all the packages needed to get
! 133: LON-CAPA running on your system, except for the LON-CAPA source itself.
! 134: </p>
! 135: <p>
! 136: Extract the archive with the following command:
! 137: </p>
! 138: <pre>
! 139: tar xf fedora_install.tar
! 140: </pre>
! 141: <p>
! 142: This creates a directory named <tt>installation</tt>.
! 143: </p>
! 144:
! 145: <h2>Installing LON-CAPA Dependencies</h2>
! 146: <p>
! 147: This section walks you through installing the packages which LON-CAPA requires.
! 148: There are a lot of dependencies to deal with. They have been grouped in a
! 149: somewhat logical fashion to make them easier to deal with. When installing
! 150: the rpms you should watch for errors.
! 151: </p><p>
! 152: The quick instructions are:
! 153: </p>
! 154: <pre>
! 155: cd installation
! 156: cd mysql
! 157: rpm -Uvh *rpm
! 158: cd ../apache
! 159: rpm -Uvh *rpm
! 160: cd ../mod_perl
! 161: rpm -Uvh *rpm
! 162: cd ../perl_dependencies
! 163: rpm -Uvh *rpm
! 164: cd ../GD
! 165: rpm -Uvh *rpm
! 166: cd ../gnuplot
! 167: rpm --install --oldpackage readline-2.2.1-6.i386.rpm
! 168: rpm --install --oldpackage --excludedocs libpng-1.0.12-2.i386.rpm
! 169: rpm -Uvh gnuplot-3.7.1-5.i386.rpm libgd-1.3-4.i386.rpm ncurses4-5.0-5.i386.rpm
! 170: cd ../misc
! 171: rpm -Uvh *rpm
! 172: cd ..
! 173: </pre>
! 174: <p>
! 175: <b>Notes:</b>
! 176: <ul>
! 177: <li>MySQL is used to store caches of data, not original copies.
! 178: Administering LON-CAPA machines does not yet mean becoming a
! 179: database administrator.</li>
! 180: <li>Apache 1.3 and mod_perl 1.x are required by LON-CAPA. These are
! 181: provided in the installation package.
! 182: <li>A specific version of Gnuplot is required by LON-CAPA. Do not
! 183: install a version different from the one included in the LON-CAPA
! 184: installation package.</li>
! 185: </ul>
! 186: </p>
! 187:
! 188: <h2>Configuring LON-CAPA Dependencies</h2>
! 189: <p>
! 190: We have prepared a script which takes care of most of the configuration that
! 191: must be done to get the newly installed packages working with LON-CAPA.
! 192: This script will retrieve the latest LON-CAPA release from
! 193: <a href="http://install.loncapa.org">http://install.loncapa.org</a>.
! 194: You will be prompted for a root password for your MySQL server. You
! 195: will need to remember this password in case you should ever need to make
! 196: changes the the server.
! 197: </p><p>
! 198: Execute the script as follows:
! 199: </p>
! 200: <pre>
! 201: cd setup;
! 202: ./install.pl
! 203: </pre>
! 204:
! 205: <h2>Determine LON-CAPA Settings</h2>
! 206: <p>
! 207: LON-CAPA requires a number of identifying parameters be set in order
! 208: for it to function at all. Below is a list with descriptions.
! 209: </p>
! 210: <dl>
! 211: <dt>Host Type (library or access)</dt>
! 212: <dd>The server must be designated a 'library' or an 'access' server. In
! 213: general you should have a library server for your instructors to create
! 214: their course content on and run their courses. Students should connect
! 215: to access servers. If you are doing the first install of LON-CAPA at
! 216: your site, or if you are playing with it for your own edification you
! 217: should make your machine a 'library' server.</dd>
! 218: <dt>LON-CAPA domain</dt>
! 219: <dd>Each site or school which installs LON-CAPA needs its own domain.
! 220: Here at MSU we use 'msu'. You should choose something short but
! 221: meaningful. <i>Restriction: One word, no hyphens, underscores, or
! 222: special characters.</i>
! 223: </dd>
! 224: <dt>LON-CAPA host id</dt>
! 225: <dd>Each LON-CAPA server requires a unique internal name. We use names
! 226: such as "msul1" for the first library server. <i>Restriction: One word,
! 227: no hyphens, underscores, or special characters.</i>
! 228: </dd>
! 229: <dt>Host administrator email</dt>
! 230: <dd>The amount of email sent to this address is relatively minimal. Messages
! 231: are sent every time the system starts up, or if the system is in
! 232: serious trouble. On a laptop, make this <tt>root@localhost</tt>.
! 233: </dd>
! 234: </dl>
! 235:
! 236: <h2>Configuring LON-CAPA</h2>
! 237: <p>
! 238: To configure and install LON-CAPA, execute the following commands:
! 239: </p>
! 240: <pre>
! 241: cd /root/loncapa-N.N (N.N should correspond to a version number like '1.1')
! 242: ./UPDATE
! 243: </pre>
! 244: <p>
! 245: You will need to enter the LON-CAPA configuration information you determined
! 246: in the previous section.
! 247: </p>
! 248:
! 249: <h2>Creating a Domain Coordinator</h2>
! 250: <p>
! 251: You will need at least one user at your site who has the role of
! 252: 'domain coordinator'. This user creates accounts for other users and
! 253: grants them additional privileges. The make_domain_coordinator.pl script
! 254: invoked below requires that you enter the users password. The password will
! 255: show in plaintext as you type it. Feel free to use the "passwd username"
! 256: command to change it later. Replace USERNAME and DOMAIN with an
! 257: appropriate user name and your domain.
! 258: </p>
! 259: <pre>
! 260: cd /root/loncapa-N.N/loncom/build
! 261: perl make_domain_coordinator.pl USERNAME DOMAIN
! 262: (WILL PROMPT FOR PASSWORD HERE)
! 263: </pre>
! 264:
! 265: <h2>Start/Restart Services</h2>
! 266: <p>
! 267: The LON-CAPA network services take a moment to start. Most misconfigurations
! 268: will be appearant at this step.
! 269: </p>
! 270: <pre>
! 271: /etc/init.d/loncontrol start
! 272: /etc/init.d/httpd start
! 273: </pre>
! 274:
! 275: <h2>Log in to your LON-CAPA Machine</h2>
! 276: <p>
! 277: Point a web browser at your new machine and log in as the domain
! 278: coordinator. Congratulations!
! 279: </p>
