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: If you like, you may contact the LON-CAPA development staff and we can 47: mail the CDs to you. Another option is to download the cd images and 48: burn them yourself, or install from a mirror site using ftp or http. 49: </p> 50: 51: <h2>Determine Network settings for your site</h2> 52: <p> 53: You will need to have the following information for your site. You must 54: have a static IP address (do not use DHCP). 55: </p> 56: <ul> 57: <li>ip address </li> 58: <li>netmask </li> 59: <li>network </li> 60: <li>broadcast </li> 61: <li>hostname </li> 62: <li>gateway </li> 63: <li>domain name server(s) </li> 64: </ul> 65: 66: <h2>Install Red Hat 7.3</h2> 67: <p> 68: When you install RedHat you will need to ensure the following (the list below 69: is in the order the issues appear in the installation of Red Hat 7.3): 70: </p> 71: <dl> 72: <dt>Installation Type</dt> 73: <dd>You should definitely do a "Server" install. We do not recommend 74: Trying to install LON-CAPA with a different installation type.</dd> 75: <dt>Partitioning your Drive</dt> 76: <dd>You may want to use the automatic partitioning feature of Red Hat, 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: lion's share of the drive should be allocated here. If you have 8 GB 80: of space for Red Hat, /home should receive 4 to 6 gigs. Be sure to 81: include adequate swap space. A minimum is 512 Megs, but you should 82: typically have 1 or 2x as much swap space as you do physical RAM.</dd> 83: <dt>Network Configuration</dt> 84: <dd>LON-CAPA will <b>not</b> work with a machine set up to use a dynamic 85: IP address. When configuring your network card, be sure to unselect 86: the DHCP option and enter in your network information.</dd> 87: <dt>Firewall Configuration</dt> 88: <dd>The installation script will remove and disable your firewall.</dd> 89: <dt>Package Group Selection</dt> 90: <dd>At a minimum, install the following packages: 91: <ul> 92: <li>NFS File Server </li> 93: <li>Windows File Server </li> 94: <li>Web Server </li> 95: </ul> 96: Other packages can be installed as you like.</dd> 97: <dt>X Windows Configuration</dt> 98: <dd>If you chose to install the X-windows packages you will need to 99: configure them. If you are unsure of the support for your video 100: card you may wish to skip the configuration.</dd> 101: </dl> 102: <p> 103: Other notes: 104: </p> 105: <ul> 106: <li>Use md5 and shadow passwords if you are given the choice (this is 107: the default). </li> 108: </ul> 109: 110: <h2>Determine LON-CAPA settings</h2> 111: <p> 112: LON-CAPA requires a number of identifying parameters be set in order 113: for it to function at all. Below is a list with descriptions. 114: </p> 115: <dl> 116: <dt>Host Type (library or access)</dt> 117: <dd>The server must be designated a 'library' or an 'access' server. In 118: general you should have a library server for your instructors to create 119: their course content on and run their courses. Students should connect 120: to access servers. If you are doing the first install of LON-CAPA at 121: your site, or if you are playing with it for your own edification, you 122: should make your machine a 'library' server.</dd> 123: <dt>LON-CAPA domain</dt> 124: <dd>Each site or school which installs LON-CAPA needs its own domain. 125: Here at MSU we use 'msu'. You should choose something short but 126: meaningful. 127: <i>Restriction: One word, no hyphens, underscores, or special characters</i> 128: </dd> 129: <dt>LON-CAPA host id</dt> 130: <dd>Each LON-CAPA server requires a unique internal name. We use names 131: such as "msul1" for the first library server. 132: <i>Restriction: One word, no hyphens, underscores, or special characters</i> 133: </dd> 134: <dt>Host administrator email</dt> 135: <dd>The amount of email sent to this address is relatively minimal. Messages 136: are sent every time the system starts up, or if the system is in 137: serious trouble. On a laptop, make this <tt>root@localhost</tt>. 138: </dd> 139: <dt>Root password for SQL database</dt> 140: <dd>In order to keep people from corrupting the MYSQL database, a root 141: password is needed. You'll need to remember this.</dd> 142: </dl> 143: 144: <h2>Install LON-CAPA</h2> 145: <p> 146: Log in as root with the password you provided during the Red Hat 147: installation process. 148: </p> 149: <pre> 150: wget http://install.loncapa.org/versions/rh73install/loncapa-rh73install.tar 151: tar xf loncapa-rh73install.tar 152: cd install 153: ./install.pl 154: </pre> 155: 156: <h2>Configure LON-CAPA</h2> 157: <p> 158: Execute the following commands 159: </p> 160: <pre> 161: cd /root/loncapa-N.N (N.N should correspond to a version number like '0.4') 162: ./UPDATE 163: </pre> 164: <p> 165: You will need to enter the LON-CAPA configuration information you requested 166: above. 167: </p> 168: 169: <h2>Picking a hosts.tab file</h2> 170: <p> 171: The "hosts.tab" file controls which LON-CAPA servers your server attempts 172: to access and which servers it will respond to. If this is your first 173: install of LON-CAPA on your network, we suggest choosing a 'standalone' 174: "hosts.tab". On a laptop, you must choose 'standalone'. 175: Please contact the support staff at www.loncapa.org for 176: information about adding more hosts to your "hosts.tab" file. 177: </p> 178: <p> 179: <b>Note:</b> for <b>non</b>-standalone configurations, you do need to add 180: yourself to the <tt>/home/httpd/lonTabs/hosts.tab</tt> to initially test your 181: configuration. Eventually, you will be added to the general cluster tables by 182: LON-CAPA staff, so this is temporary. A <tt>hosts.tab</tt> entry has the 183: format 184: </p> 185: <pre> 186: lonHostID:domain:hosttype:dns-name:ipaddress 187: </pre> 188: <p> 189: for example 190: </p> 191: <pre> 192: 103l5:library:s17.lite.msu.edu:35.8.63.27 193: </pre> 194: <p> 195: Please edit this file with a UNIX editor, not a PC or Mac one, so that the 196: linebreaks are correct. 197: </p> 198: 199: <h2>Creating a Domain Coordinator</h2> 200: <p> 201: You will need at least one user at your site who has the role of 202: 'domain coordinator'. This user creates accounts for other users and 203: grants them additional privileges. The make_domain_coordinator.pl script 204: invoked below requires that you enter the users password. The password will 205: show in plaintext as you type it. Feel free to use the "passwd username" 206: command to change it later. Replace USERNAME and DOMAIN with an 207: appropriate user name and your domain. 208: </p> 209: <pre> 210: cd /root/loncapa/loncom/build 211: perl make_domain_coordinator.pl USERNAME DOMAIN 212: (WILL PROMPT FOR PASSWORD HERE) 213: mkdir ~USERNAME/public_html 214: chown USERNAME:www ~USERNAME/public_html 215: chmod 0775 ~USERNAME/public_html 216: chmod a+x ~USERNAME 217: </pre> 218: 219: <h2>Start/Restart Services</h2> 220: <p> 221: The services take about 10 minutes to start. 222: </p> 223: <pre> 224: /etc/init.d/loncontrol start 225: /etc/init.d/httpd restart 226: </pre> 227: 228: <h2>Make Sure that Services Autostart on Boot</h2> 229: <p>On Redhat 7.3 it is not guaranteed that Apache and MySQL automatically 230: restart on boot. You should run /usr/sbin/ntsysv and set the following 231: daemons to be started at boot: 232: </p> 233: <pre> 234: httpd 235: mysqld 236: </pre> 237: <p> 238: It is not necessary to reboot after doing this as they should already be 239: running by this point in the installation. 240: </p> 241: <pre> 242: /etc/init.d/httpd restart 243: /etc/init.d/mysqld restart 244: </pre> 245: 246: <h2>Log in to your LON-CAPA Machine</h2> 247: <p> 248: Point a web browser at your new machine and log in as the domain 249: coordinator.
