Reconfigured document - do update as soon as possible.  Turn off httpd
upon initial boot of system.  (There was a slapper infection on a LON-CAPA
install in East Texas.).  Added lecture on keeping your system up to date.

However, it is still a 22: non-trivial undertaking and experience with Red Hat Linux will make this 23: process easier. You will be required to log in to the machine and execute 24: some routine Unix commands. Some familiarity with Linux is assumed. 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 Red Hat 7.3 </li> 33: <li> Gather information for installing Red Hat </li> 34: <li> Install Red Hat 7.3 </li> 35: <li> Determine your LON-CAPA Settings </li> 36: <li> Install LON-CAPA </li> 37: <li> Configure LON-CAPA </li> 38: <li> Pick a hosts.tab file </li> 39: <li> Create a Domain Coordinator </li> 40: <li> Start/Restart services </li> 41: <li> Log in to LON-CAPA </li> 42: </ol> 43: 44: <h2>Obtain the Red Hat 7.3 installation CDs</h2> 45: <p> 46: These are freely available on the internet. 47: </p> 48: 49: <h2>Determine Network settings for your site</h2> 50: <p> 51: You will need to have the following information for your site. You must 52: have a static IP address (do not use DHCP). 53: </p> 54: <ul> 55: <li>ip address </li> 56: <li>netmask </li> 57: <li>network </li> 58: <li>broadcast </li> 59: <li>hostname </li> 60: <li>gateway </li> 61: <li>domain name server(s) </li> 62: </ul> 63: 64: <h2>Install Red Hat 7.3</h2> 65: <p> 66: When you install RedHat you will need to ensure the following (the list below 67: is in the order the issues appear in the installation of Red Hat 7.3): 68: </p> 69: <dl> 70: <dt>Installation Type</dt> 71: <dd>You should definitely do a "Server" install. We do not recommend 72: Trying to install LON-CAPA with a different installation type.</dd> 73: <dt>Partitioning your Drive</dt> 74: <dd>You may want to use the automatic partitioning feature of Red Hat, 75: however you should review the results and be prepared to modify them. 76: LON-CAPA resource files are stored in the /home directory, so the 77: lion's share of the drive should be allocated here. If you have 8 GB 78: of space for Red Hat, /home should receive 4 to 6 gigs. 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.</dd> 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, be sure to unselect 84: the DHCP option and enter in your network information.</dd> 85: <dt>Firewall Configuration</dt> 86: <dd>The installation script will remove and disable your firewall.</dd> 87: <dt>Package Group Selection</dt> 88: <dd>At a minimum, install the following packages: 89: <ul> 90: <li>NFS File Server </li> 91: <li>Windows File Server </li> 92: <li>Web Server </li> 93: </ul> 94: Other packages can be installed as you like.</dd> 95: <dt>X Windows Configuration</dt> 96: <dd>If you chose to install the X-windows packages you will need to 97: configure them. If you are unsure of the support for your video 98: card you may wish to skip the configuration.</dd> 99: </dl> 100: <p> 101: Other notes: 102: </p> 103: <ul> 104: <li>Use md5 and shadow passwords if you are given the choice (this is 105: the default). </li> 106: </ul> 107: 108: <h2>Determine LON-CAPA settings</h2> 109: <p> 110: LON-CAPA requires a number of identifying parameters be set in order 111: for it to function at all. Below is a list with descriptions. 112: </p> 113: <dl> 114: <dt>Host Type (library or access)</dt> 115: <dd>The server must be designated a 'library' or an 'access' server. In 116: general you should have a library server for your instructors to create 117: their course content on and run their courses. Students should connect 118: to access servers. If you are doing the first install of LON-CAPA at 119: your site, or if you are playing with it for your own edification, you 120: should make your machine a 'library' server.</dd> 121: <dt>LON-CAPA domain</dt> 122: <dd>Each site or school which installs LON-CAPA needs its own domain. 123: Here at MSU we use 'msu'. You should choose something short but 124: meaningful. 125: <i>Restriction: One word, no hyphens, underscores, or special characters</i> 126: </dd> 127: <dt>LON-CAPA host id</dt> 128: <dd>Each LON-CAPA server requires a unique internal name. We use names 129: such as "msul1" for the first library server. 130: <i>Restriction: One word, no hyphens, underscores, or special characters</i> 131: </dd> 132: <dt>Host administrator email</dt> 133: <dd>The amount of email sent to this address is relatively minimal. Messages 134: are sent every time the system starts up, or if the system is in 135: serious trouble. On a laptop, make this <tt>root@localhost</tt>. 136: </dd> 137: <dt>Root password for SQL database</dt> 138: <dd>In order to keep people from corrupting the MYSQL database, a root 139: password is needed. You'll need to remember this.</dd> 140: </dl> 141: 142: <h2>Install LON-CAPA</h2> 143: <p> 144: Log in as root with the password you provided during the Red Hat 145: installation process. 146: </p><p> 147: Stop the http daemon while we're installing LON-CAPA. 148: <pre> 149: /etc/init.d/httpd stop 150: </pre> 151: </p><p> 152: Retrieve the LON-CAPA installation package 153: <pre> 154: wget http://install.loncapa.org/versions/rh73install/loncapa-rh73install.tar 155: tar xf loncapa-rh73install.tar 156: cd install 157: ./install.pl 158: </pre> 159: </p> 160: 161: <h2>Configure LON-CAPA</h2> 162: <p> 163: Execute the following commands 164: </p> 165: <pre> 166: cd /root/loncapa-N.N (N.N should correspond to a version number like '0.6') 167: ./UPDATE 168: </pre> 169: <p> 170: You will need to enter the LON-CAPA configuration information you requested 171: above. 172: </p> 173: 174: <h2>Update your system</h2> 175: <p> 176: It is very important that you update your LON-CAPA system to use the 177: latest RedHat packages. LON-CAPA uses CHECKRPMS to notify users their system 178: needs updating. 179: <pre> 180: /usr/local/loncapa/bin/CHECKRPMS 181: </pre> 182: CHECKRPMS will give you the option of downloading the updates you need. 183: Say yes. Then issue the following commands: 184: <pre> 185: cd /tmp/loncapa_rpm_updates' 186: rpm -Uvh * 187: </pre> 188: </p><p> 189: You will need to reboot your system to begin running the new Linux Kernel 190: put out by RedHat. You can wait until the end of the LON-CAPA installation 191: process to reboot. 192: </p><p> 193: Congratulate yourself - your system is up to date. Please do your best to 194: keep it that way! When LON-CAPA is installed it sets itself up to run 195: CHECKRPMS script every night and email you the results. 196: <b>Please do not ignore these emails.</b> 197: You will need to update the RPMs yourself when it notifies you. 198: Keeping your system up-to-date goes a long way towards ensuring the 199: integrity of your student records. 200: </p> 201: 202: <h2>Picking a hosts.tab file</h2> 203: <p> 204: The "hosts.tab" file controls which LON-CAPA servers your server attempts 205: to access and which servers it will respond to. If this is your first 206: install of LON-CAPA on your network, we suggest choosing a 'standalone' 207: "hosts.tab". On a laptop, you must choose 'standalone'. 208: Please contact the support staff at www.loncapa.org for 209: information about adding more hosts to your "hosts.tab" file. 210: </p> 211: <p> 212: <b>Note:</b> for <b>non</b>-standalone configurations, you do need to add 213: yourself to the <tt>/home/httpd/lonTabs/hosts.tab</tt> to initially test your 214: configuration. Eventually, you will be added to the general cluster tables by 215: LON-CAPA staff, so this is temporary. A <tt>hosts.tab</tt> entry has the 216: format 217: </p> 218: <pre> 219: lonHostID:domain:hosttype:dns-name:ipaddress 220: </pre> 221: <p> 222: for example 223: </p> 224: <pre> 225: 103l5:library:s17.lite.msu.edu:35.8.63.27 226: </pre> 227: <p> 228: Please edit this file with a UNIX editor, not a PC or Mac one, so that the 229: linebreaks are correct. 230: </p> 231: 232: <h2>Creating a Domain Coordinator</h2> 233: <p> 234: You will need at least one user at your site who has the role of 235: 'domain coordinator'. This user creates accounts for other users and 236: grants them additional privileges. The make_domain_coordinator.pl script 237: invoked below requires that you enter the users password. The password will 238: show in plaintext as you type it. Feel free to use the "passwd username" 239: command to change it later. Replace USERNAME and DOMAIN with an 240: appropriate user name and your domain. 241: </p> 242: <pre> 243: cd /root/loncapa-N.N/loncom/build 244: perl make_domain_coordinator.pl USERNAME DOMAIN 245: (WILL PROMPT FOR PASSWORD HERE) 246: mkdir ~USERNAME/public_html 247: chown USERNAME:www ~USERNAME/public_html 248: chmod 0775 ~USERNAME/public_html 249: chmod a+x ~USERNAME 250: </pre> 251: 252: <h2>Start/Restart Services</h2> 253: <p> 254: The LON-CAPA network services take about a minute to start. 255: </p> 256: <pre> 257: /etc/init.d/loncontrol start 258: /etc/init.d/httpd restart 259: </pre> 260: 261: <h2>Make Sure that Services Autostart on Boot</h2> 262: <p>On Redhat 7.3 it is not guaranteed that Apache and MySQL automatically 263: restart on boot. You should run /usr/sbin/ntsysv and set the following 264: daemons to be started at boot: 265: </p> 266: <pre> 267: httpd 268: mysqld 269: </pre> 270: <p> 271: It is not necessary to reboot after doing this as they should already be 272: running by this point in the installation. 273: </p> 274: <pre> 275: /etc/init.d/httpd restart 276: /etc/init.d/mysqld restart 277: </pre> 278: 279: <h2>Log in to your LON-CAPA Machine</h2> 280: <p> 281: Point a web browser at your new machine and log in as the domain 282: coordinator.
