How to use on Solaris based operating sytsems - acmesh-official/acme.sh GitHub Wiki

I ran this on Illumos, with Apache22

1. get acme.sh

pkg install gnu-sed wget

your path needs to include GNU sed before "Sun" sed, and include the path to "apachectl"
you need to set "ACME_DIR" to be somewhere at least chmod 755 readable by the Apache web server (i.e. don't use /root/acme because the /root directory is not read/exec by "other". The default ACME_DIR is set to be the automounted "/home/.acme" directory. (Neil suggests possibly using /tmp/.acme)

export PATH ; PATH=/usr/gnu/bin:/usr/bin:/usr/sbin:/sbin:/usr/apache2/2.2/bin
export ACME_DIR ; ACME_DIR=/tmp/.acme

Please don't specify the "-w" option, this will only cause confusion
if you are using Proxy forwarding, like I was, or any other similar configuration; you will need to modify the Apache configuration to allow "/.well-known" to pass through
I never had any luck with curl, so I force the use of wget. YMMV
if you are going to play with this a lot, you will want to add "--test" to the command, which will use the "staging area" of letencrypt.com, and/or --debug to check that it is working. If you do use the "staging area"; when you come to do this for real you will need to add "--force" to the command

./acme.sh --issue --apache -d online.domain.com --use-wget

the simple command to add this to cron is:

./acme.sh --install-cronjob

however you might well need to copy/move the "acme.sh" command into ~/.acme.sh for this to pick up the location correctly.
