Звучит как занятый 80 порт, попробуйте поменять в /etc/nginx/sites-available/default listen на 81

Answer 1

[Alexey Dmitriev]

Есть же информация об ошибке "nginx: configuration file /etc/nginx/nginx.conf test failed".
Запустите nginx -t - покажет строку с ошибкой.

Вот такая история
nginx: the configuration file /etc/nginx/nginx.conf syntax is ok
nginx: [emerg] socket() [::]:80 failed (97: Unknown error)
nginx: configuration file /etc/nginx/nginx.conf test failed

[Alexey Dmitriev]

Серая Мышь, ну вот - можете же, когда хотите. Гуглите, изучайте матчасть

Answer 2

[mikes]

устанавливая рокетчат устанавливается и caddy и висит на портах 80 и 443 которые пытается занять nginx
остановите caddy и nginx при установке отработает штатно

Answer 3

[Алексей Черемисин]

У Вас невалидная конфигурация nginx, проверьте количество закрывающих и открывающих скобочек фигурных {} в /etc/nginx/sites-available/default
Ну и перед перезапуском nginx -t для проверки.

nginx: configuration file /etc/nginx/nginx.conf test failed

[Алексей Черемисин]

Серая Мышь, netstat -anp | grep LIST | grep 80 смотрим, что торчит на 80-м и 443-м портах.

Answer 4

[AUser0]

У вас уже какой-то сервис занял порт 80, на котором должен работать nginx. Найдите и остановите, а лучше удалите сервис, занимающий 80-й порт. Поможет команда netstat -nltp |grep :80, в конце строки - имя сервиса.
