supervisor nginx terminado pelo SIGABRT; inesperado

Question

Estou executando o .net core no Ubuntu. Se eu apenas executar meu aplicativo com dotnet run , meu aplicativo será executado com sucesso

Mas quero executar meu aplicativo no nginx com supervisor Aqui está minha configuração:

nginx / etc / nginx / sites-disponível / padrão:

# You should look at the following URL's in order to grasp a solid understanding
# of Nginx configuration files in order to fully unleash the power of Nginx.

# http://wiki.nginx.org/QuickStart
# http://wiki.nginx.org/Configuration
#
# Generally, you will want to move this file somewhere, and start with a clean
# file but keep this around for reference. Or just disable in sites-enabled.

Acho que tenho um problema com a configuração. Pode ser que alguém possa ajudar?

    

Answer 1

Certifique-se de que seu arquivo .conf de supervisor use o .dll que você publicou.

Se você olhar o arquivo de Scott como abaixo, certifique-se de que a dll que você publicou é a que está no arquivo. Para mim foi testweb.dll.

link

[program:dotnettest]
command=/usr/bin/dotnet /var/dotnettest/testweb.dll --server.urls:http://*:5123
directory=/var/dotnettest/
autostart=true
autorestart=true
stderr_logfile=/var/log/dotnettest.err.log
stdout_logfile=/var/log/dotnettest.out.log
environment=ASPNETCORE_ENVIRONMENT=Production
user=www-data
stopsignal=INT

Eu tive alguns outros problemas que eu postei aqui ... link

    

Answer 2

Encontrei o mesmo problema e consegui resolvê-lo alterando a primeira linha para usar --port = 5010 em vez de --server.urls: http: // *: 5010

Recebi mais detalhes sobre onde o erro estava ocorrendo observando o log de erros:

$ cat /var/log/supervisor/testapp.err.log

Quando eu executei esse comando, vi o seguinte erro:

Unhandled Exception: System.FormatException: Value for switch '--server.urls:http://*:5010' is missing.

Isso me fez pensar em mudar para a opção --port em vez de --server depois de analisar as Documentação dos arquivos de configuração do supervisor

Mudar a primeira linha do meu arquivo .conf para ler como o abaixo resolveu o problema:

command=/usr/bin/dotnet /var/dotnettest/testapp.dll --port=5010

    

Answer 3

há um erro aqui: --server.urls:http://*:5000 - deve haver um = entre o server.urls e o http... .

Então você precisa corrigi-lo para --server.urls=http://*:5000
