    2: a newly installed LON-CAPA system

    7: 
    8: There are 17 steps to this procedure.  (Eventually
    9: this procedure will be replaced with interfaces.
   10: Till then, enjoy the UNIX command line.)
   11: 
   12: You need to decide on three pieces of information
   13: to create a domain coordinator.
   14: 
   15: * USERNAME (kermit, albert, joe, etc)
   16: * DOMAIN (should be the same as lonDefDomain in /etc/httpd/conf/access.conf)
   17: * PASSWORD (don't tell me)
   18: 
   19: The examples in these instructions will be based
   20: on three example pieces of information:
   21: * USERNAME=dc103
   22: * DOMAIN=103
   23: * PASSWORD=sesame
   24: 
   25: You will also need to know your "root" password
   26: and your "www" password.
   27: 
   28: 1. login as root on your Linux system
   29:    [prompt %] su
   30: 
   31: 2 (as root). add the user
   32:    Command: [prompt %] /usr/sbin/adduser USERNAME
   33:    Example: [prompt %] /usr/sbin/adduser dc103
   34: 
   35: 3 (as root). enter in a password
   36:    Command: [prompt %] passwd USERNAME
   37:             New UNIX password: PASSWORD
   38:             Retype new UNIX passwd: PASSWORD
   39:    Example: [prompt %] passwd dc103
   40:             New UNIX password: sesame
   41:             Retype new UNIX passwd: sesame
   42: 
   43: 4 (as root). Make www a member of the new user group.
   44:    You will need to change 1 line in /etc/group
   45:    Assuming USERNAME=dc103
   46:    (your values are different)
   47:    Change this line in /etc/group
   48:    dc103:x:NUMBER:   
   49:    to be
   50:    dc103:x:NUMBER:www
   51: 
   52: 5. Login as the new user
   53:    Command: [prompt %] su USERNAME
   54:    Example: [prompt %] su dc103
   55: 
   56: 6 (as USERNAME).  Create a public_html directory for the new user.
   57:    (This step does not need to be done.  Only if new user will
   58:     also be an "author" on the system.)
   59:    Command: [prompt %] install -d /home/USERNAME/public_html
   60:    Example: [prompt %] install -d /home/dc103/public_html
   61: 
   62: 7. (as USERNAME). Set permissions for /home/dc103 and /home/dc103/public_html
   63: #    to be readable and writeable by www.
   64: # See immediately below for newer instructions:
   65: #   Command: [prompt %] chmod g+rwx /home/USERNAME
   66: #            [prompt %] chmod g+rwx /home/USERNAME/public_html
   67: #   Example: [prompt %] chmod g+rwx /home/dc103
   68: #            [prompt %] chmod g+rwx /home/dc103/public_html
   69:     New instructions:
   70:     (This step does not need to be done. Only if the new user will
   71:     also be an author on the system.)
   72:     As root, make /home world executable (chmod a+x /home)
   73:     As dc103 (or whatever the domain coordinator name is,
   74:     chmod g+x /home/dc103
   75:     chmod g+srw /home/dc103/public_html
   76: 
   77: 8. login as user=www
   78:    Command: [prompt %] su www
   79:             Password: WWWPASSWORD
   80: 
   81: 9. (as www). cd /home/httpd/lonUsers
   82: 
   83: 10. (as www) Create user directory for your new user.
   84:    Let U equal first letter of USERNAME
   85:    Let S equal second letter of USERNAME
   86:    Let E equal third letter of USERNAME
   87:    Command: [prompt %] install -d DOMAIN/U/S/E/USERNAME
   88:    Example: [prompt %] install -d 103/d/c/1/dc103
   89: 
   90: 11. (as www) Enter the newly created user directory.
   91:    Command: [prompt %] cd DOMAIN/U/S/E/USERNAME
   92:    Example: [prompt %] cd 103/d/c/1/dc103
   93: 
   94: 12. (as www). Set your password mechanism to 'unix' 
   95:    Command: [prompt %] echo "unix:" > passwd
   96: 
   97: 13. (as www). Create and run the following script with the arguments
   98:   Create the file described below "script.pl" or whatever name you want
   99:   (it is in CVS:loncapa/doc/rolesmanip.pl).
  100: 
  101:   Command: [prompt %] perl script.pl DOMAIN USERNAME
  102:   Example: [prompt %] perl script.pl 103 dc103
  103: 
  104: #!/usr/bin/perl
  105: 
  106: # quick temporary script
  107: # brought up-to-date by Scott Harrison, 03/01/2001
  108: 
  109: 
  110: print "Usage: rolesmanip.pl DOMAIN USERNAME\n" unless @ARGV;
  111: 
  112: my $domain=shift @ARGV;
  113: my $name=shift @ARGV;
  114: 
  115: my ($l1,$l2,$l3)=split(//,substr($name,0,3));
  116: 
  117: use GDBM_File;
  118: my %hash;
  119:         tie(%hash,'GDBM_File',
  120: "/home/httpd/lonUsers/$domain/$l1/$l2/$l3/$name/roles.db",
  121: 	    &GDBM_WRCREAT,0640);
  122: 
  123: $hash{'/'.$domain.'/_dc'}='dc';
  124: open OUT, ">/home/httpd/lonUsers/$domain/$l1/$l2/$l3/$name/roles.hist";

  128: close OUT;
  129: 
  130: untie %hash;
  131: 
  132: 14. login as root
  133:     Command: [prompt %] su
  134: 
  135: 15. Restart the lon processes (/etc/rc.d/init.d/loncontrol restart)
  136: 16. Restart the httpd processes (/etc/rc.d/init.d/httpd restart)
  137: 17. You may further define the domain coordinator user (i.e. dc103)
  138:     by going to http://MACHINENAME/adm/createuser.
