using acme-tiny with apache2. split signed_chain.crt into separate files.

cd /root/acme_tiny
python ./acme_tiny.py --account-key ./account.key --csr ./domain.csr --acme-dir /var/www/challenges/ > ./signed_chain.crt.tmp || exit
mv ./signed_chain.crt.tmp ./signed_chain.crt

# Split signed_chain.crt into two files domain_signed.pem and chain.pem
# for apache2 support
python -c 'f = open("signed_chain.crt", "r"); l = f.read(); f.close(); end = "\n\n"; certs = l.split(end); f = open("domain_signed.pem", "w"); f.write(certs[0]+"\n"); f.close(); f = open("chain.pem", "w"); f.write(end.join(certs[1:])+"\n"); f.close()'
