! 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>
