.netcore2.0 发布CentOS7

1.一般在windows pc上使用vscode 开发好.netcore 程序如果需要发布到其他平台需要注意一些事情

首先需要明白2个概念：FDD（Framework-dependent deployment）和 SCD （Self-contained deployment）

2.# FDD

Framework-dependent deployment. As the name implies, framework-dependent deployment (FDD) relies on the presence of a shared system-wide version of .NET Core on the target system. Because .NET Core is already present, your app is also portable between installations of .NET Core. Your app contains only its own code and any third-party dependencies that are outside of the .NET Core libraries. FDDs contain .dll files that can be launched by using the dotnet utility from the command line. For example, dotnet app.dll runs an application named app.

3.#

SCD 

Self-contained deployment. Unlike FDD, a self-contained deployment (SCD) doesn't rely on the presence of shared components on the target system. All components, including both the .NET Core libraries and the .NET Core runtime, are included with the application and are isolated from other .NET Core applications. SCDs include an executable (such as app.exe on Windows platforms for an application named app), which is a renamed version of the platform-specific .NET Core host, and a .dll file (such as app.dll), which is the actual application.

5.# 修改 .csproj 项目文件

<RuntimeIdentifiers>win7-x64;centos.-x64</RuntimeIdentifiers>

完整如下图：

6.# 直接执行 build 如果依赖项目较多可能会等很久

先执行 dotnet restore 命令

这样会下载安装一些依赖项目等完成后

再执行 build 命令

测试下在 windows 下是 ok 的

最后执行publish 指令：

dotnet publish -c Release -r centos.-x64

最后会生成Release版本：

最后生成文件非常多：

下一步使用FTP工具上传到 CentOS publish 目录：

最后一步使用 putty 命令执行就可以了

dotnet xxx.dll

--------------------------------------------------------------------------------------------------------------

注意事项 以上是基于 FDD模式 (感觉4G技术 娃哈哈哈哈）

要提前手工安装 .netcore 2.0 SDK

参考命令如下：

# 解压安装文件
$ tar -xzf ~/dotnet/dotnet-dev-centos-x64.1.0.-preview1-.tar.gz
# 软连接
ln -s /home/jake/leak/dotnet/dotnet /usr/local/bin
# 删除软连接
rm -rf /usr/local/bin/dotnet
# 查看版本
dotnet --version
