■list-unit-filesに認識されているか確認
$ sudo systemctl list-unit-files --type=service|grep nginx
nginx.service                     disabled
  
■有効化する
$ sudo systemctl enable nginx.service
Created symlink from /etc/systemd/system/multi-user.target.wants/nginx.service to /usr/lib/systemd/system/nginx.service.

確認

■起動確認
$ sudo systemctl start nginx.service
$ ps -ef|grep ngin
root      9887     1  0 16:29 ?        00:00:00 nginx: master process /usr/local/nginx/sbin/nginx -c /usr/local/nginx/conf/nginx.conf

root      9971 32341  0 16:29 pts/1    00:00:00 grep --color=auto ngin
  
■systemctl statusで確認
□確認項目
・PIDがpsで引いたものと合致しているか
・ExecStart, ExecStartPreがそれぞれ動いたか
