Everything has been installed, but before you can run the site, you will need
|
|
to edit several config files:
|
|
|
|
${BLUE_BOLD}Caddy${RESET}: /home/caddy/Caddyfile
|
|
|
|
Get an API token from Cloudflare and add it to the Caddyfile to allow the
|
|
ACME challenge to succeed. The token must have the Zone / Zone / Read and
|
|
Zone / DNS / Edit permissions (as laid out in the following links).
|
|
|
|
https://github.com/caddy-dns/cloudflare
|
|
https://github.com/libdns/cloudflare
|
|
|
|
Add the Cloudflare token to allow the ACME challenge to succeed, and add
|
|
the correct domains. (Don't forget to include both the normal and wildcard
|
|
domains.)
|
|
|
|
Also, in the CGI config, add the name of the Git branch you would like to
|
|
use when deploying. For example, a deployment of the beta site should use
|
|
the `beta` branch.
|
|
|
|
${BLUE_BOLD}Monit${RESET}: ~/.monitrc
|
|
|
|
Add the password for the email server.
|
|
|
|
${BLUE_BOLD}Deploy Secret${RESET}: /home/hmn/hmn/server/deploy.conf
|
|
|
|
First, go to GitLab and add a webhook with a secret. Set it to trigger on
|
|
push events for the branch you are using for deploys.
|
|
|
|
https://git.handmade.network/hmn/hmn/hooks
|
|
|
|
Then, edit the above file and fill in the secret value from the
|
|
GitLab webhook.
|
|
|
|
${BLUE_BOLD}Website${RESET}: /home/hmn/hmn/src/config/config.go
|
|
|
|
Fill out everything :)
|
|
|
|
Then rebuild the site:
|
|
|
|
su hmn
|
|
cd ~/hmn
|
|
go build -o /home/hmn/bin/hmn src/main.go
|
|
|
|
${BLUE_BOLD}Cinera${RESET}: /home/hmn/hmn/cinera/cinera.conf
|
|
|
|
Add the correct domain.
|
|
|
|
|
|
${BLUE_BOLD}===== Next steps =====${RESET}
|
|
|
|
Restore a database backup:
|
|
|
|
su hmn
|
|
cd ~
|
|
/home/hmn/bin/hmn seedfile <I dunno man figure it out>
|
|
|
|
Start up Caddy:
|
|
|
|
systemctl start caddy
|
|
|
|
Then run the deploy script:
|
|
|
|
/home/hmn/hmn/server/deploy.sh
|
|
|
|
