Information about Fedora is available from 9: <a href="http://fedora.redhat.com/">http://fedora.redhat.com/</a>. 10: More information about LON-CAPA is available from 11: <a href="http://www.loncapa.org">http://www.loncapa.org</a> and 12: <a href="http://install.loncapa.org">http://install.loncapa.org</a>. 13: </p><p> 14: These instructions assume you have installed Fedora Core 3 on your system 15: and it is running properly. All of the LON-CAPA data is stored in 16: /home/httpd. MySQL is used to store temporary caches of system data, by 17: default this uses storage space in /var/lib/mysql. You will want to be sure 18: you have enough disk space for these two partitions. 19: </p><p> 20: Please keep your system up to date. By default, LON-CAPA will add its 21: own repository to your /etc/yum.conf file. Additionally, yum will be run 22: every morning to determine if there are any packages which need to be 23: upgraded. If there are, an email will be sent to the server administrator 24: (specified in the LON-CAPA installation). It behooves you to keep your 25: system up to date. 26: </p> 27: 28: <h2>Installation Overview</h2> 29: <p> 30: The installation must be done as root. 31: </p><p> 32: The installation process takes the following steps: 33: </p> 34: <ol> 35: <li> Install LON-CAPA </li> 36: <li> Create a Domain Coordinator </li> 37: <li> Start/Restart services </li> 38: <li> Log in to LON-CAPA </li> 39: </ol> 40: 41: <h2>Install LON-CAPA</h2> 42: <h3>Remove conflicting packages</h3> 43: <p> 44: You will need to remove the following packages which conflict with LON-CAPA. 45: <ul> 46: <li> httpd 47: <li> php 48: <li> mod_throttle 49: <li> mod_bandwidth 50: <li> mod_perl 51: </ul> 52: List the packages you have installed that match by executing: 53: <pre> 54: rpm -q -f | grep PACKAGENAME 55: </pre> 56: You can remove the packages individually using 57: <pre> 58: rpm -e PACKAGENAME 59: </pre> 60: You will need to remove all of the packages which depend on the ones you are 61: removing. 62: You can remove the associated packages en mass if you are satisfied the prior 63: command selected all the appropriate packages: 64: <pre> 65: rpm -q -a | grep PACKAGENAME | rpm -e 66: </pre> 67: </p> 68: 69: <h3>Install prerequisites</h3> 70: <p> 71: We have provided many of the packages needed for LON-CAPA in the installation 72: bundle. They reside in the prerequisites directory. You will need to install them using the following commands: 73: <pre> 74: cd prerequisites 75: rpm -Uvh *rpm 76: </pre> 77: You will need to resolve any errors this process generated. For packages that are already installed you can simply remove them from the directory: 78: <pre> 79: mv CONFLICTINPACKAGE*.rpm .. 80: </pre> 81: And try the installation command again. If there are required packages which 82: have not been installed, these should be found on your Fedora Core 3 installation CDs. 83: </p> 84: 85: <h3>Determine LON-CAPA Settings</h3> 86: <p> 87: LON-CAPA requires a number of identifying parameters be set in order 88: for it to function at all. Below is a list with descriptions. 89: </p> 90: <dl> 91: <dt>Host Type (library or access)</dt> 92: <dd>The server must be designated a 'library' or an 'access' server. In 93: general you should have a library server for your instructors to create 94: their course content on and run their courses. Students should connect 95: to access servers. If you are doing the first install of LON-CAPA at 96: your site, or if you are playing with it for your own edification you 97: should make your machine a 'library' server.</dd> 98: <dt>LON-CAPA domain</dt> 99: <dd>Each site or school which installs LON-CAPA needs its own domain. 100: Here at MSU we use 'msu'. You should choose something short but 101: meaningful. <i>Restriction: One word, no hyphens, underscores, or 102: special characters.</i> 103: </dd> 104: <dt>LON-CAPA host id</dt> 105: <dd>Each LON-CAPA server requires a unique internal name. We use names 106: such as "msul1" for the first library server. <i>Restriction: One word, 107: no hyphens, underscores, or special characters.</i> 108: </dd> 109: <dt>Host administrator email</dt> 110: <dd>The amount of email sent to this address is relatively minimal. Messages 111: are sent every time the system starts up, or if the system is in 112: serious trouble. On a laptop, make this <tt>root@localhost</tt>. 113: </dd> 114: </dl> 115: 116: <h3>Install and Configuring LON-CAPA</h3> 117: <p> 118: To configure and install LON-CAPA, execute the following commands: 119: </p> 120: <pre> 121: cd ~/loncapa_install/ 122: ./install.pl 123: </pre> 124: You will need to enter a root password for MySQL. Once this is complete 125: you will need to execute: 126: <pre> 127: cd /root/loncapa-1.3.2 128: ./UPDATE 129: </pre> 130: <p> 131: You will need to enter the LON-CAPA configuration information you determined 132: in the previous section. 133: </p> 134: 135: <h2>Creating a Domain Coordinator</h2> 136: <p> 137: You will need at least one user at your site who has the role of 138: 'domain coordinator'. This user creates accounts for other users and 139: grants them additional privileges. The make_domain_coordinator.pl script 140: invoked below requires that you enter the users password. The password will 141: show in plaintext as you type it. Feel free to use the "passwd username" 142: command to change it later. Replace USERNAME and DOMAIN with an 143: appropriate user name and your domain. 144: </p> 145: <pre> 146: cd /root/loncapa-1.3.2/loncom/build 147: perl make_domain_coordinator.pl USERNAME DOMAIN 148: (WILL PROMPT FOR PASSWORD HERE) 149: mkdir ~USERNAME/public_html 150: chown USERNAME:www ~USERNAME/public_html 151: chmod 0775 ~USERNAME/public_html 152: chmod a+x ~USERNAME 153: </pre> 154: 155: <h2>Start/Restart Services</h2> 156: <p> 157: The LON-CAPA network services take a moment to start. Most misconfigurations 158: will be appearant at this step. 159: </p> 160: <pre> 161: /etc/init.d/loncontrol start 162: /etc/init.d/httpd start 163: </pre> 164: <p> 165: If you receive warnings when starting the httpd about missing perl modules, 166: please make sure you followed the instructions in 167: <b>Installing LON-CAPA Dependencies</b>. If you still have errors, please 168: contact the LON-CAPA development team. 169: </p> 170: <h2>Log in to your LON-CAPA Machine</h2> 171: <p> 172: Point a web browser at your new machine and log in as the domain 173: coordinator. Congratulations! 174: </p> 175: 176: <h2>If Things aren't working right</h2> 177: <p> 178: If you've followed the steps above and the server doesn't start or you think 179: there's something wrong, please get in touch with the LON-CAPA developers. 180: If there were errors in installation of the dependency RPMs or during the 181: automatic setup, please send us as much information as possible. 182: If some part of this document is unclear please let us know. 183: </p> 184: 185: </body> 186: </html>
