Deployment environment

OS:CentOS7

.NET Core SDK:2.2.402

Install .NET Core SDK

1.1 installation depends on yum install libunwind libicu

Repo of dotnet, you need to register the Microsoft signing key and add the Microsoft product key

Rpm-Uvh https://packages.microsoft.com/config/rhel/7/packages-microsoft-prod.rpm

1.2 install dotnet SDK

Yum updateyum install dotnet-sdk-2.2

1.3 Verification View

# dotnet-info

.net Core SDK (reflecting any global.json): Version: 2.2.402Commit: c7f2f96116Runtime Environment:OS Name: centosOS Version: 7OS Platform: LinuxRID: centos.7-x64Base Path: / usr/share/dotnet/sdk/2.2.402/Host (useful for support): Version: 2.2.8Commit: b9aa1abc51.NET Core SDKs installed:2.2.402 [/ usr/share/dotnet/sdk] .NET Core runtimes installed:Microsoft.AspNetCore.All 2.2 .8 [/ usr/share/dotnet/shared/Microsoft.AspNetCore.All] Microsoft.AspNetCore.App 2.2.8 [/ usr/share/dotnet/shared/Microsoft.AspNetCore.App] Microsoft.NETCore.App 2.2.8 [/ usr/share/dotnet/shared/Microsoft.NETCore.App] To install additional .NET Core runtimes or SDKs: https://aka.ms/dotnet-download

Create a soft link for the dotnet command:

/ usr/bin/dotnet-> / usr/share/dotnet/dotnet

1.5 deploy and start the .NET Core project application

Go to the project application:

Cd / usr/soft/package/Web

Start the dotnet application

Dotnet / usr/soft/package/Web/HiCore.PreventFraudAPI.Web.dll

There is a problem here. The application launched in the above way is not started in the background, and if Ctrl+Z exits the application, a Daemon daemon is needed to allow the application to run independently. Here, Supervisor is introduced.

Nginx configuration application virtual host

Here Nginx is installed slightly, mainly under the description of the virtual host configuration file of Nginx configuration. The default proxy_pass reverse port is 5000, which can be modified according to the actual project. Here, the port of the application project configuration of the .NET Core is configured in the hosting.json file in the project, such as: hosting.json {"server.urls": "http://*:8001"}"

The virtual host file configured by Nginx is configured as follows:

Server {listen 80location position / {proxy_pass http://localhost:8001; proxy_http_version 1.1; proxy_set_header Upgrade $http_upgrade; proxy_set_header Connection keep-alive; proxy_set_header Host $host; proxy_cache_bypass $http_upgrade;}}

After the file is saved, execute the command nginx-s reload to restart Nginx to access it.

Supervisor configuration daemon

Supervisor is a process management tool under the Linux/Unix system developed with Python. It can make the process break away from the terminal and become the background Daemon daemon. Monitor the status of the process in real time, and restart automatically when an exception exits.

3.1 install Supervisor

It is officially recommended that the preferred installation method is to use easy_install, which is a feature of setuptools (Python package management tool). Yum install python-setuptools

Installation

Easy_install supervisor

Version

Supervisord-version

3.2 initialize the supervisor configuration

Mkdir / etc/supervisor

Mkdir-p / etc/supervisor/conf.d

Echo_supervisord_conf > / etc/supervisor/supervisord.conf

Open the supervisord.conf file and modify the default [include] configuration item as follows:

[include] files = conf.d/*.conf

Supervisor automatically loads the files with the .conf suffix in the / etc/supervisor/conf.d directory as a common service configuration. Each process managed by Supervisor writes a separate configuration file and places it in that directory, while the / etc/supervisor/supervisord.conf configuration file retains the common configuration.

3.3.Writing .NET Core project application configuration

Vim / etc/supervisor/conf.d/netcoreAPI.conf

[program:PreventFraudAPI.Web] command=dotnet Web.dll # Startup Command directory=/usr/soft/package/FraudAPI.Web # Startup Application Directory autostart=true # when Supervisord starts, whether the program starts startretries=5 # automatically starts startretries=5 # when the program exits, and the number of automatic retries that failed. Default is 3startsecs=1 # automatic restart interval user=root # start process user, default rootpriority=999 # default 999 Small value priority starts stderr_logfile=/var/log//PreventFraudAPI.err.log # error_logstdout_logfile=/var/log//PreventFraudAPI.out.log # out_logenvironment=ASPNETCORE_ENVIRONMENT=Production # process environment variable stopsignal=INT # signal used to kill the program when a request is stopped

Start the Supervisor service command, but do not start it here, and then set Supervisor to boot.

Supervisord-c / etc/supervisor/supervisord.conf

3.4.Setting Supervisor to boot

Create the Supervisor startup service script supervisor.service, directory / usr/lib/systemd/system/.

The content of the supervisor.service script:

[Unit] Description=Supervisor daemon [service] Type=forkingExecStart=/usr/bin/supervisord-c / etc/supervisor/supervisord.confExecStop=/usr/bin/supervisorctl $OPTIONS shutdownExecReload=/usr/bin/supervisorctl $OPTIONS reloadKillMode=processRestart=on-failureRestartSec=42s [Install] WantedBy=multi-user.target

Set up boot boot

Systemctl enable supervisor

3.5 Supervisorctl Management process

After the Supervisor service starts, the processes managed by it run in the background. Client processes can be managed through the supervisorctl command.

# supervisorctl

PreventFraudAPI.Web RUNNING pid 15921, uptime 0:22:51supervisor > supervisor > helpdefault commands (type help): = = add exit open reload restart start tail avail fg pid remove shutdown status update clear maintail quit reread signal stop version
