1: <html><head><title>Setting up a Red Hat7.3 LON-CAPA Server</title></head><body> 2:  3: <h1>Setting up a Red Hat7.3 LON-CAPA Server</h1> 4: 5: <h2>Before you begin</h2> 6: <p> 7: Installing Linux is getting easier and easier. However, it is still a 8: non-trivial undertaking and experience with Red Hat Linux will make this 9: process easier. You will be required to log in to the machine and execute 10: some routine Unix commands. Some familiarity with Linux is assumed. 11: </p> 12: 13: <h2>Installation Overview</h2> 14: <p> 15: The installation process takes the following steps: 16: <ol> 17: <li> Obtain Red Hat 7.3 18: <li> Gather information for installing Red Hat 19: <li> Install Red Hat 7.3 20: <li> Determine your LON-CAPA Settings 21: <li> Install LON-CAPA 22: <li> Configure LON-CAPA 23: <li> Pick a hosts.tab file 24: <li> Create a Domain Coordinator 25: <li> Start/Restart services 26: <li> Log in to LON-CAPA 27: </ol> 28: </p> 29: 30: <h2>Obtain the Red Hat 7.3 installation CDs</h2> 31: <p> 32: If you like, you may contact the LON-CAPA development staff and we can 33: mail the CDs to you. Another option is to download the cd images and 34: burn them yourself. 35: </p> 36: 37: <h2>Gather information for the Red Hat Installation</h2> 38: <p> 39: You will need to gather some network information for your server. You will 40: also need to determine some of the LON-CAPA configuration information before 41: you begin. 42: </p> 43: <h3>Network settings for your site</h3> 44: <p> 45: <ul> 46: <li>ip address 47: <li>netmask 48: <li>network 49: <li>broadcast 50: <li>hostname 51: <li>gateway 52: <li>domain name server(s) 53: </ul> 54: </p> 55: 56: <h2>Install Red Hat 7.3</h2> 57: <p> 58: When you install RedHat you will need to ensure the following (the list below 59: is in the order the issues appear in the installation of Red Hat 7.3): 60: <dl> 61: <dt>Installation Type 62: <dd>You should definitely do a "Server" install. We do not recommend 63: Trying to install LON-CAPA with a different installation type. 64: <dt>Partitioning your Drive 65: <dd>You may want to use the automatic partitioning feature of Red Hat, 66: however you should review the results and be prepared to modify them. 67: LON-CAPA resource files are stored in the /home directory, so the 68: lion's share of the drive should be allocated here. If you have 8 GB 69: of space for Red Hat, /home should receive 4 to 6 gigs. Be sure to 70: include adequate swap space. A minimum is 512 Megs, but you should 71: typically have 1 or 2x as much swap space as you do physical RAM. 72: <dt>Network Configuration 73: <dd>LON-CAPA will <b>not</b> work with a machine set up to use a dynamic 74: IP address. When configuring your network card, be sure to unselect 75: the DHCP option and enter in your network information. 76: <dt>Firewall Configuration 77: <dd>The installation script will remove and disable your firewall. 78: <dt>Package Group Selection 79: <dd>At a minimum, install the following packages: 80: <ul> 81: <li>NFS File Server 82: <li>Windows File Server 83: <li>Web Server 84: </ul> 85: Other packages can be installed as you like. 86: <dt>X Windows Configuration 87: <dd>If you chose to install the X-windows packages you will need to 88: configure them. If you are unsure of the support for your video 89: card you may wish to skip the configuration. 90: </dl> 91: Other notes: 92: <ul> 93: <li>Use md5 and shadow passwords if you are given the choice (this is 94: the default). 95: </ul> 96: </p> 97: 98: <h2>Determine LON-CAPA settings</h2> 99: <p> 100: LON-CAPA requires a number of identifying parameters be set in order 101: for it to function at all. Below is a list with descriptions. 102: <dl> 103: <dt>Host Type (library or access) 104: <dd>The server must be designated a 'library' or an 'access' server. In 105: general you should have a library server for your instructors to create 106: their course content on and run their courses. Students should connect 107: to access servers. If you are doing the first install of LON-CAPA at 108: your site, or if you are playing with it for your own edification, you 109: should make your machine a 'library' server. 110: <dt>LON-CAPA domain 111: <dd>Each site or school which installs LON-CAPA needs its own domain. 112: Here at MSU we use 'msu'. You should choose something short but 113: meaningful. 114: <dt>LON-CAPA host id 115: <dd>Each LON-CAPA server requires a unique internal name. We use names 116: such as "msul1" for the first library server. 117: <dt>Host administrator email 118: <dd>The amount of email sent to this address is relatively minimal. Messages 119: are sent every time the system starts up. 120: <dt>Root password for SQL database 121: <dd>In order to keep people from corrupting the MYSQL database, a root 122: password is needed. You'll need to remember this. 123: </dl> 124: </p> 125: 126: <h2>Install LON-CAPA</h2> 127: <p> 128: Log in as root with the password you provided during the Red Hat 129: installation process. 130: <pre> 131: wget http://install.loncapa.org/versions/rh73install/loncapa-rh73install.tar 132: tar xf loncapa-rh73install.tar 133: cd install 134: ./install.pl 135: </pre> 136: </p> 137: 138: <h2>Configure LON-CAPA</h2> 139: <p> 140: Execute the following commands 141: <pre> 142: cd /root/loncapa/ 143: ./UPDATE 144: </pre> 145: You will need to enter the LON-CAPA configuration information you requested 146: above. Additionally, you will need to enter the following information 147: (options 5 and 6 in the menu): 148: <dl> 149: <dt>Cache Expiration Time 150: <dd>86400 151: <dt>Server Load 152: <dd>2.0 153: </dl> 154: </p> 155: 156: <h2>Picking a hosts.tab file</h2> 157: The "hosts.tab" file controls which LON-CAPA servers your server attempts 158: to access and which servers it will respond to. If this is your first 159: install of LON-CAPA on your network, we suggest choosing a 'standalone' 160: "hosts.tab". Please contact the support staff at www.loncapa.org for 161: information about adding more hosts to your "hosts.tab" file. 162: 163: <h2>Creating a Domain Coordinator</h2> 164: <p> 165: You will need at least one user at your site who has the role of 166: 'domain coordinator'. This user creates accounts for other users and 167: grants them additional privileges. The make_domain_coordinator.pl script 168: invoked below requires that you enter the users password. The password will 169: show in plaintext as you type it. Feel free to use the passwd username 170: command to change it later. Replace USERNAME and DOMAIN with an 171: appropriate user name and your domain. 172: <pre> 173: cd /root/loncapa/loncom/build 174: perl make_domain_coordinator.pl USERNAME DOMAIN 175: mkdir ~USERNAME/public_html 176: chown USERNAME:www ~USERNAME/public_html 177: chmod 0775 ~USERNAME/public_html 178: </pre> 179: </p> 180: 181: <h2>Start/Restart Services</h2> 182: <p> 183: The services take about 10 minutes to start. 184: <pre> 185: /etc/init.d/loncontrol start 186: /etc/init.d/httpd restart 187: </pre> 188: </p> 189: 190: <h2>Log in to your LON-CAPA Machine</h2> 191: <p> 192: Point a web browser at your new machine and log in as the domain 193: coordinator. Congratulations! 194: </p> 195: 196: 197:
