openssl rsa -in privkey.pem -out key.pem
openssl x509 -in cert.csr -out cert.pem -req -signkey key.pem -days 1001
cat key.pem >> cert.pem
cp cert.pem /etc/nginx/sites-available

server {
  server_name my-vhost.xxx.com;
  root        /home/myaccount/vhost/my-vhost
  access_log  /var/log/nginx/my-vhost.access.log;

Certbot 2.x (Let's Encrypt)

• Certbot official site

sudo snap install --classic certbot
# sudo ln -s /snap/bin/certbot /usr/bin/certbot

Install nginx on macOS 10.13+

Default nginx package in Homebrew is missing many modules.

Tap 3rd party package is useful for development.

brew tap denji/nginx

brew install nginx-full \
  --with-echo-module \
  --with-autols-module \
  --with-geoip2-module \
  --with-http2 \
  --with-upload-module \
  --with-upload-progress-module

Running nginx as nobody is inconvenient for development. Running as login account is better.

/usr/local/etc/nginx/nginx.conf:2

#     user      group
user  myaccount admin;

When using nobody, response would be 403 forbidden and hard to debug.

Like this: (/usr/local/var/log/nginx/error.log)
