! 6: <h1>Installing LON-CAPA on a minimal Fedora Core 4 Linux System</h1>
! 7: <p>
! 8: This document guides you through the process of setting up a new LON-CAPA
! 9: server running Fedora Core 4 (FC4) with a minimum of packages installed.
! 10: The computer will be configured solely as a LON-CAPA server and will be
! 11: expected to have no other services running. Your server is expected to have
! 12: a reasonably fast connection to the internet.
! 13: </p><p>
! 14: More information is available at
! 15: <a href="http://install.lon-capa.org/">http://install.lon-capa.org/</a>.
! 16: </p>

! 18: <h2>Before you begin</h2>
! 19: <p>
! 20: Installing Linux is getting easier and easier. However, it is still a
! 21: non-trivial undertaking and experience with Red Hat Linux will make this
! 22: process easier. You will be required to log in to the machine and execute
! 23: some routine Unix commands.Familiarity with the Apache web server, mod_perl,
! 24: perl, and MySQL are not required to install and run LON-CAPA.
! 25: </p>
! 26:
! 27: <h2>Installation Overview</h2>
! 28: <p>
! 29: The installation process takes the following steps:
! 30: </p>
! 31: <ol>
! 32: <li> Obtain Fedora Core 4 installation CDs</li>
! 33: <li> Determine Network Settings</li>
! 34: <li> Install Fedora Core 4 </li>
! 35: <li> Update your system </li>
! 36: <li> Install LON-CAPA </li>
! 37: <li> Create a Domain Coordinator </li>
! 38: <li> Start/Restart services </li>
! 39: <li> Log in to LON-CAPA </li>
! 40: </ol>
! 41:
! 42: <h2>Obtain Fedora Core 4</h2>
! 43: <p>
! 44: FC4 ISO files can be obtained from the projects main site,
! 45: <a href="http://fedora.redhat.com/">http://fedora.redhat.com/</a>.
! 46: For the minimal install you will need only the first ISO image (e.g., FC4-i386-disc1.iso CD for x86-compatible 32-bit).
! 47: </p>
! 48:
! 49: <h2>Determine Network Settings</h2>
! 50: <p>
! 51: You will need to know the following network settings for your installation.
! 52: <b>Note:</b>You must have a static IP address to use LON-CAPA.
! 53: DHCP is <em>not</em> supported.
! 54: </p>
! 55: <ul>
! 56: <li>ip address </li>
! 57: <li>netmask </li>
! 58: <li>hostname </li>
! 59: <li>gateway </li>
! 60: <li>domain name server(s) </li>
! 61: </ul>
! 62:
! 63: <h2>Minimal FC4 Install</h2>
! 64: <p>
! 65: Installing Fedora is quite easy if you've installed any of the Red Hat products
! 66: before. Some documentation is available from
! 67: <a href="http://fedora.redhat.com/projects/anaconda-installer/">
! 68: http://fedora.redhat.com/projects/anaconda-installer/</a>.
! 69: Most of the installation screens are self explanatory.
! 70: There are a few steps that require comment and are dealt with below.
! 71: </p>
! 72: <dl style="list-style:square outside none">
! 73: <dt>Installation Type</dt>
! 74: <dd>Choose "Server" installation
! 75: <dt>Partitioning your Drive</dt>
! 76: <dd>You may want to use the automatic partitioning feature of the installer,
! 77: however you should review the results and be prepared to modify them.
! 78: LON-CAPA resource files are stored in the /home directory, so the
! 79: majority of the disk space should be allocated here. If you have 20 GB
! 80: of space for FC4, /home should receive at least 10 to 12 gigs.
! 81: Since MySQL uses the /var filesystem to store its databases you should
! 82: have at least 4 gigs of space available on /var. Be sure to
! 83: include adequate swap space. A minimum is 512 Megs, but you should
! 84: typically have 1 or 2x as much swap space as you do physical RAM.</dd>
! 85: <dt>Network Configuration</dt>
! 86: <dd>LON-CAPA will <b>not</b> work with a machine set up to use a dynamic
! 87: IP address. When configuring your network card, be sure to unselect
! 88: the DHCP option and enter in your network information.</dd>
! 89: <dt>Firewall Configuration</dt>
! 90: <dd>Select SSH (remote login), HTTP/HTTPS (web server).</dd>
! 91: <dt>SELinux Configuration</dt>
! 92: <dd>Choose an SElinux setting of 'disabled' or 'warn', unless you are
! 93: familiar with SElinux and writing security policies
! 94: <b>and want to help us write a security policy for LON-CAPA</b>.
! 95: <dt>Package Group Selection</dt>
! 96: <dd>Choose 'Minimal' which is the last item on the list.</dd>
! 97: </dl>
! 98: <p>
! 99: Finish installing your server, reboot it, and log in as root.
! 100: </p>
! 101:
! 102: <!---
! 103:
! 104: The firewall should be customized to allow incoming ssh and www.
! 105: Additional ports used by LON-CAPA are 5663 and 8080.
! 106: Enter these in the entry box as <nobr>"5663:tcp, 8080:tcp"</nobr>.</dd>
! 107:
! 108: -->
! 109:
! 110: <h2>Update your system</h2>
! 111: <p>
! 112: Update your system to the latest versions of the system software using yum.
! 113: Yum is configured to check encyption keys for the packages it installs, so
! 114: you need to import the keys before invoking yum.
! 115: </p>
! 116: <pre>
! 117: rpm --import /etc/pki/rpm-gpg/RPM-GPG-KEY-fedora
! 118: rpm --import /etc/pki/rpm-gpg/RPM-GPG-KEY-fedora-extras
! 119: yum update
! 120: </pre>
! 121: <p>
! 122: Reboot your system before continuing with the installation.
! 123: </p>
! 124: <p>
! 125: Retrieve the FC4_loncapa_yum file from the LON-CAPA install site:
! 126: </p>
! 127: <pre>
! 128: wget http://install.loncapa.org/versions/fedora/4/FC4_loncapa_yum.conf
! 129: </pre>
! 130: <p>
! 131: Install the FC4_loncapa_yum.conf
! 132: </p>
! 133: <pre>
! 134: mv /etc/yum.conf /etc/yum.conf.backup
! 135: cp FC4_loncapa_yum.conf /etc/yum.conf
! 136: yum update
! 137: </pre>
! 138: </p>

! 141: <h2>Installing LON-CAPA</h2>
! 142: <h3>Install prerequisites</h3>
! 143: <p> Execute: </p>
! 144: <pre>
! 145: yum install LONCAPA-prerequisites
! 146: </pre><p>
! 147: This may take a moment due to LON-CAPA's large number of dependencies.
! 148: </p>
! 149: <h3>Retrieve and execute LON-CAPA setup program</h3>
! 150: <p>
! 151: Retrieve the LON-CAPA setup with the following command:
! 152: </p>
! 153: <pre>
! 154: wget http://install.loncapa.org/versions/fedora/4/fedora_install.tar
! 155: </pre>
! 156: <p>
! 157: Extract the archive with the following command:
! 158: </p>
! 159: <pre>
! 160: tar xf fedora_install.tar
! 161: </pre>
! 162: <p>
! 163: This creates a directory named <tt>installation</tt>. Change to it and
! 164: execute the setup script with the following commands:
! 165: </p>
! 166: <pre>
! 167: cd installation
! 168: ./install.pl
! 169: </pre>
! 170: <p>
! 171: This script will prompt you for the MySQL root password and will download the latest LON-CAPA release.<br />
! 172: You can safely ignore the following warnings from gcc 4 when compiling pwauth:<br />
! 173: <tt>
! 174: pwauth.c: In function ‘lastlog’:
! 175: <ul>
! 176: <li>pwauth.c:541: warning: incompatible implicit declaration of built-in function ‘strncpy’</li>
! 177: <li>pwauth.c:543: warning: incompatible implicit declaration of built-in function ‘strlen’</li>
! 178: </ul>
! 179: pwauth.c: In function ‘main’:
! 180: <ul>
! 181: <li>pwauth.c:692: warning: incompatible implicit declaration of built-in function ‘strlen’</li>
! 182: </ul>
! 183: </tt>
! 184:
! 185: </p>
! 186:
! 187: <h3>Determine LON-CAPA Settings</h3>
! 188: <p>
! 189: LON-CAPA requires a number of identifying parameters to be set in order
! 190: for it to function at all. Below is a list with descriptions.
! 191: </p>
! 192: <dl>
! 193: <dt>Host Type (library or access)</dt>
! 194: <dd>The server must be designated a 'library' or an 'access' server. In
! 195: general you should have a library server for your instructors to create
! 196: their course content on and run their courses. Students should connect
! 197: to access servers. If you are doing the first install of LON-CAPA at
! 198: your site, or if you are playing with it for your own edification you
! 199: should make your machine a 'library' server.</dd>
! 200: <dt>LON-CAPA domain</dt>
! 201: <dd>Each site or school which installs LON-CAPA needs its own domain.
! 202: Here at MSU we use 'msu'. You should choose something short but
! 203: meaningful. <i>Restriction: One word, no hyphens, underscores, or
! 204: special characters.</i>
! 205: </dd>
! 206: <dt>LON-CAPA host id</dt>
! 207: <dd>Each LON-CAPA server requires a unique internal name. We use names
! 208: such as "msul1" for the first library server. <i>Restriction: One word,
! 209: no hyphens, underscores, or special characters.</i>
! 210: </dd>
! 211: <dt>Host administrator email</dt>
! 212: <dd>The amount of email sent to this address is relatively minimal. Messages
! 213: are sent every time the system starts up, or if the system is in
! 214: serious trouble. On a laptop, make this <tt>root@localhost</tt>.
! 215: </dd>
! 216: </dl>
! 217:
! 218: <h3>Configuring LON-CAPA</h3>
! 219: <p>
! 220: To configure and install LON-CAPA, execute the following commands:
! 221: </p>
! 222: <pre>
! 223: cd /root/loncapa-N.N (N.N should correspond to a version number like '1.3')
! 224: ./UPDATE
! 225: </pre>
! 226: <p>
! 227: You will need to enter the LON-CAPA configuration information you determined
! 228: in the previous section.
! 229: </p>
! 230:
! 231: <h2>Creating a Domain Coordinator</h2>
! 232: <p>
! 233: You will need at least one user at your site who has the role of
! 234: 'domain coordinator'. This user creates accounts for other users and
! 235: grants them additional privileges. The make_domain_coordinator.pl script
! 236: invoked below requires that you enter the users password. The password will
! 237: show in plaintext as you type it. Feel free to use the "passwd username"
! 238: command to change it later. Replace USERNAME and DOMAIN with an
! 239: appropriate user name and your domain.
! 240: </p>
! 241: <pre>
! 242: cd /root/loncapa-N.N/loncom/build
! 243: perl make_domain_coordinator.pl USERNAME DOMAIN
! 244: (WILL PROMPT FOR PASSWORD HERE)
! 245: mkdir ~USERNAME/public_html
! 246: chown USERNAME:www ~USERNAME/public_html
! 247: chmod 0775 ~USERNAME/public_html
! 248: chmod a+x ~USERNAME
! 249: </pre>
! 250:
! 251: <h2>Start/Restart Services</h2>
! 252: <p>
! 253: The LON-CAPA network services take a moment to start. Most misconfigurations
! 254: will be appearant at this step.
! 255: </p>
! 256: <pre>
! 257: /etc/init.d/loncontrol start
! 258: /etc/init.d/httpd start
! 259: </pre>
! 260: <p>
! 261: If you receive warnings when starting the httpd about missing perl modules,
! 262: please make sure you followed the instructions in
! 263: <b>Installing LON-CAPA Dependencies</b>. If you still have errors, please
! 264: contact the LON-CAPA development team.
! 265: </p>
! 266: <h2>Log in to your LON-CAPA Machine</h2>
! 267: <p>
! 268: Point a web browser at your new machine and log in as the domain
! 269: coordinator. Congratulations!
! 270: </p>
! 271:
! 272: <h2>If things aren't working right</h2>
! 273: <p>
! 274: If you've followed the steps above and the server doesn't start or you think
! 275: there's something wrong, please get in touch with the LON-CAPA developers.
! 276: If there were errors in installation of the dependency RPMs or during the
! 277: automatic setup, please send us as much information as possible.
! 278: If some part of this document is unclear please let us know.
! 279: </p>
