Supervisorをインストールしてdotnetを動かす

■ 環境

• Ubuntu20.04(vagrant+virtualBox)

• dotnet version3.1

• すでにnginxでhttpsリバースプロキシを構築し.Net Coreアプリを動かすでnginxでリバースプロキシが構築されていること。

There’s an tool called Supervisor that is good at that so I’ll add it.

WebサーバーSupervisorをインストール

$ sudo apt-get install supervisor

DotnetアプリをRelease Buildする

$ sudo mkdir -p /var/aspnetcore
$ cd ~/hellomvc
$ sudo dotnet publish --configuration Release
Microsoft (R) Build Engine version 16.6.0+5ff7b0c9e for .NET Core

  Determining projects to restore...
  Restored /home/vagrant/data/hellomvc/hellomvc.csproj (in 2.47 sec).
  hellomvc -> /home/vagrant/data/hellomvc/bin/Release/netcoreapp3.1/hellomvc.dll
  hellomvc -> /home/vagrant/data/hellomvc/bin/Release/netcoreapp3.1/publish/

アプリケーションの公開ディレクトリへコピーする

$ sudo cp -R ./bin/Release/netcoreapp3.1/publish/* /var/aspnetcore/
$ ls /var/aspnetcore/
appsettings.Development.json  appsettings.json  hellomvc  hellomvc.deps.json  hellomvc.dll  hellomvc.pdb  hellomvc.runtimeconfig.json  web.config

 SupervisorのConfigファイルを生成する(/etc/supervisor/conf.d/hellomvc.conf)

$ sudo vim /etc/supervisor/conf.d/hellomvc.conf
[program:dotnettest]
command=/usr/bin/dotnet /var/aspnetcore/hellomvc.dll --urls "http://*:5000"
directory=/var/aspnetcore/
autostart=true
autorestart=true
stderr_logfile=/var/log/hellomvc.err.log
stdout_logfile=/var/log/hellomvc.out.log
environment=ASPNETCORE_ENVIRONMENT=Production
user=www-data
stopsignal=INT

※dotnetコマンドをたたいて、公開ディレクトリのdllと、5000ポートを指定していますね。

いよいよ、supervisor起動

$ sudo service supervisor stop
$ sudo service supervisor start
$ sudo tail -f /var/log/supervisor/supervisord.log
