Letsencrypt Is it possible to install letsencrypt without creating a new vhost?

Not really as letsencrypt requires domain validation and that requires verifying domain name DNS wise goes to the server IP and that you own the domain. The verification is done via webroot authentication which means for Centmin Mod, letsencrypt client i.e. addons/acemtool.sh underlying acme.sh client will auto create a verification file in domain.com's web root at /home/nginx/domains/domain.com/public and then letsencrypt servers access domain.com/path/to/verification/file to confirm your domain. So you do need create a new vhost via centmin.sh menu option 2 if you enable addons/acmetool.sh in 123.09beta01. There's also manual methods if you don't want to use centmin.sh menu option 2 via addons/acmetool.sh. But it still involves creating nginx vhost as webroot authentication is need for letsencrypt to verify your domain.

manual methods

• addons/acmetool.sh manual instruction mode
• Official Nginx Vhost Generator Add Letsencrypt SSL Support

 

Oh i thought you meant get letsencrypt ssl cert without creating an existing domain nginx vhost site. If you already have existing nginx vhost site, you can directly use addon/acmetool.sh for automated letsencrypt on new or existing domain but it's beta and needs testing and feedback. Or you can do it manually via manual methods

manual methods

• addons/acmetool.sh manual instruction mode
• Official Nginx Vhost Generator Add Letsencrypt SSL Support <-- probably the easier method to follow

which work on existing nginx vhost domains

 

then manual methods outlined above are what you need to do if you don't want to beta test addons/acmetool.sh directly

 

beta testing may mess up your nginx vhost files in certain combination or choices i.e. if you do test ssl cert then re-run for live ssl cert so yes may cause site downtime.

The manual methods won't cause any such as you manually make the changes to the nginx vhost files as instructed

no if you follow manual methods they ssl certs get auto renewed via underlying acme.sh cronjob

 

• Official Nginx Vhost Generator Add Letsencrypt SSL Support <-- probably the easier method to follow

direct link to official nginx vhost generator at https://centminmod.com/vhost.php

 

no read the auto generated instructions

creating the vhost and vhost file are 2 separate things

creating vhost means directory structures at /home/nginx/domains/domain.com/* etc

while creating vhost file structure is needed for letsencrypt and is what the vhost generator does

 

works for me for utahfishkeepers.us - no http just domain name itself

 

no follow all generated steps that is just the first part (first 3 cmds)

backup existing domain.us.conf file just in case

 

no no.. you need to follow all steps listed on entire generated page down to the new domain.com.ssl.conf and replacing the 3 ssl cert file paths.

everything on generated page needs to be done including the other commands
