.NET Core SDK：2.2.402?
安裝.NET Core SDK?
1.1?安裝依賴yum install libunwind libicudotnet?的repo，需注冊(cè)Microsoft簽名密鑰并添加Microsoft產(chǎn)品密鑰?
rpm -Uvh https://packages.microsoft.com/config/rhel/7/packages-microsoft-prod.rpm1.2?安裝dotnet SDK?
yum updateyum install dotnet-sdk-2.21.3?驗(yàn)證查看?

1.5?部署啟動(dòng).NET Core項(xiàng)目應(yīng)用?
進(jìn)入到項(xiàng)目應(yīng)用：?
cd /usr/soft/package/Web?
啟動(dòng)dotnet應(yīng)用?
dotnet /usr/soft/package/Web/HiCore.PreventFraudAPI.Web.dll這里存在一問(wèn)題，以上方式啟動(dòng)的應(yīng)用非后臺(tái)啟動(dòng)，如果Ctrl+Z就退出了應(yīng)用，所以這里需要一個(gè)Daemon守護(hù)進(jìn)程，讓?xiě)?yīng)用獨(dú)立的運(yùn)行，這里引入Supervisor。?
Nginx配置應(yīng)用虛擬主機(jī)?
這里Nginx安裝略，主要將Nginx配置的虛擬主機(jī)配置文件說(shuō)明下。默認(rèn)proxy_pass反代的端口為5000，可根據(jù)實(shí)際項(xiàng)目修改。這里.NET Core的應(yīng)用項(xiàng)目配置的端口在項(xiàng)目中的hosting.json文件里配置，如：hosting.json {"server.urls": "http://*:8001"}Nginx配置的該虛擬主機(jī)文件配置如：?
server {listen 80;location / { ???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;}}文件保存后，執(zhí)行命令nginx -s reload重啟Nginx即可訪問(wèn)。?
Supervisor配置守護(hù)進(jìn)程?
Supervisor是用Python開(kāi)發(fā)的Linux/Unix系統(tǒng)下的一個(gè)進(jìn)程管理工具?？梢允惯M(jìn)程脫離終端，成為后臺(tái)Daemon守護(hù)進(jìn)程。實(shí)時(shí)監(jiān)控進(jìn)程狀態(tài)，異常退出時(shí)能自動(dòng)重啟。?
3.1?安裝Supervisor?
官方推薦首選安裝方法是使用easy_install，它是setuptools（Python包管理工具）的一個(gè)功能。yum install python-setuptools安裝?
easy_install supervisor版本?
supervisord --version3.2?初始化supervisor配置?
mkdir /etc/supervisor?
mkdir -p /etc/supervisor/conf.d?
echo_supervisord_conf > /etc/supervisor/supervisord.conf打開(kāi)supervisord.conf文件，修改默認(rèn)[include]配置項(xiàng)，改為如下：?
[include]files = conf.d/*.confSupervisor會(huì)自動(dòng)加載?/etc/supervisor/conf.d目錄下.conf后綴的文件作為共同服務(wù)配置。Supervisor管理的每個(gè)進(jìn)程單獨(dú)寫(xiě)一個(gè)配置文件放在該目錄下，/etc/supervisor/supervisord.conf配置文件中保留公共配置。?
3.3?編寫(xiě).NET Core項(xiàng)目應(yīng)用配置?
