一、编译发布Asp.net core 应用

直接使用vs2019编译发布后,通过ftp上传到centos的 /www/ 目录下，不再赘述。

二、centos安装asp.net core runtime和nginx

1、安装asp.net core runtime

#注册 Microsoft 密钥。注册产品存储库。安装必需的依赖项。sudo rpm -Uvh https://packages.microsoft.com/config/centos/7/packages-microsoft-prod.rpm#安装 .NET Core 运行时sudo yum install aspnetcore-runtime-3.1

2、安装nginx

添加源：

sudo rpm -Uvh http://nginx.org/packages/centos/7/noarch/RPMS/nginx-release-centos-7-0.el7.ngx.noarch.rpm

安装 nginx

$ sudo yum -y install nginx

Nginx常用命令

# 卸载 nginx$ sudo yum remove nginx # 设置开机启动 $ sudo systemctl enable nginx # 启动 nginx 服务$ sudo service nginx start # 停止 nginx 服务$ sudo service nginx stop # 重启 nginx 服务$ sudo service nginx restart # 重新加载配置，一般是在修改过 nginx 配置文件时使用。$ sudo service nginx reload #查看nginx版本$ nginx -v 

3、使用nginx反向代理

在 /etc/nginx/ 目录下新建AspnetCoreDemo.conf，内容如下

server { listen 80; server_name example.com; location / { proxy_pass http://localhost:5000; 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; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; proxy_set_header X-Forwarded-Proto $scheme; }}

4、重新加载nginx配置

# 验证配置文件的语法$ sudo nginx -t # 强制 Nginx 选取更改。$ sudo nginx -s reload 

三、添加Systemd守护

1、Systemd service内容如下

路径 /etc/systemd/system/AspnetCoreDemo.service 新建文件

[Unit]Description=AspnetCoreDemo running on Centos[Service]WorkingDirectory=/wwwExecStart=/usr/bin/dotnet /www/AspnetCoreDemo.dllRestart=always# Restart service after 10 seconds if the dotnet service crashes:RestartSec=10KillSignal=SIGINTSyslogIdentifier=AspnetCoreDemoUser=www-data#Production：生产环境 Development：开发环境Environment=ASPNETCORE_ENVIRONMENT=Development Environment=DOTNET_PRINT_TELEMETRY_MESSAGE=false[Install]WantedBy=multi-user.target

2、Systemd基本操作命令

#启用systemctl enable AspnetCoreDemo.service#启动systemctl start AspnetCoreDemo.service#状态systemctl status AspnetCoreDemo.service#重启systemctl restart AspnetCoreDemo.service#关闭systemctl stop AspnetCoreDemo.service

四、防火墙设置（不需要端口访问，可忽略此步）

1、开放端口firewall-cmd --zone=public --add-port=5000/tcp --permanent # 开放5000端口firewall-cmd --zone=public --remove-port=5000/tcp --permanent #关闭5000端口firewall-cmd --reload # 配置立即生效 2、查看防火墙所有开放的端口firewall-cmd --zone=public --list-ports 3.、关闭防火墙如果要开放的端口太多，嫌麻烦，可以关闭防火墙，安全性自行评估systemctl stop firewalld.service 4、查看防火墙状态 firewall-cmd --state
