There are three parts to an REXEC installation:

1. Installing and configuring SSLeay.
2. Installing REXEC.
3. Starting the daemons and running applications.

1. Installing and configuring SSLeay.
(Yes, this should be automated and pathnames should be configurable.)

• gzip -d SSLeay-0.9.0b.tar.gz
• tar xvf SSLeay-0.9.0b.tar.gz
• cd SSLeay-0.9.0b
• Read the INSTALL file. Three things will are required:
  1. Telling SSL where perl is.
  2. Telling SSL where you want its home to be (e.g., /usr/local/ssl)
  3. Telling SSL what type of system you have (e.g. linux-elf).
• cp ssleay.cnf SSLeay-0.9.0b/apps/ssleay.cnf
• make
• make install
• mkdir -p /usr/mill/include
• mkdir -p /usr/mill/lib/ssl
• cd /usr/local/ssl
• Add /usr/local/ssl/bin to your PATH.
• cp include/* /usr/mill/include
• cp lib/* /usr/mill/lib/ssl
• bin/CA.sh -newca (creates directory demoCA).
  (Use 'Certificate Authority' for name.)
• mkdir -p /usr/mill/pkg/ssl/etc
• mv demoCA /usr/mill/pkg/ssl/etc/ca
• cd /usr/mill/pkg/ssl/etc/ca
• cp cacert.pem certs
• cd certs
• ln -s cacert.pem `x509 -noout -hash < cacert.pem`.0
• ssleay genrsa > svr_key.pem
• ssleay req -new -key svr_key.pem -out svr_req.pem
  (Use 'Cluster Node' for name.)
• ssleay ca -in svr_req.pem -out svr_cert.pem
• For each node in the cluster which will run jobs,
  
  • cp svr_key.pem /etc/svr_key.pem
    
  • cp svr_cert.pem /etc/svr_cert.pem
    
  • chmod 700 /etc/svr_key.pem
    
  • chmod 700 /etc/svr_cert.pem
    
• For each user who will run jobs on the cluster,
  (Users will execute these commands, except for the signing at the end.)
  • mkdir ~/.rexec
  • chmod 700 ~/.rexec
  • cd ~/.rexec
  • ssleay genrsa > cli_key.pem
  • ssleay req -new -key cli_key.pem -out cli_req.pem
    (Use your login name.)
  • ssleay ca -in cli_req.pem -out cli_cert.pem (CA does this)

2. Installing REXEC

• gzip -d rexec-1.3.tar.gz
• tar xvf rexec-1.3.tar
• cd rexec-1.3
• ./configure (defaults to /usr/local)
• make
• make install

3. Starting the daemons and running applications

• Read the README file in the rexec-1.3 directory.
