环境
{
"操作系统":"CentOS 7.5 64位",
"CPU":"1核",
"内存":"2GB",
"公网带宽":"1Mbps"
}0.[校验]先查看系统是否已经安装了dotnet
[[email protected]_0_12_centos /]# dotnet
-bash: dotnet: command not found
如果返回"command not found",继续看下去,
如果已经安装了dotnet,请关闭本页面.
1.[先决条件]查看yum版本号
[[email protected]_0_12_centos /]# yum --version
3.4.3
[[email protected]_0_12_centos /]# yum update
//省略N多代码...
Complete!关yum啥事情?
1.看了篇博客,说要更新下yum版本,所以我查看了下yum的版本,
紧接着不管现在的版本号,就更新了yum的版本...
2.微软官方文档上也是用yum这种方式来进行安装的.
This article describes how to use a package manager to install .NET Core on CentOS 7.
2.[正式开始.热身阶段]开始之前,先需要做以下准备
- Register the Microsoft key
- register the product repository
- Install required dependencies
[[email protected]_0_12_centos ~]# sudo rpm -Uvh https://packages.microsoft.com/config/centos/7/packages-microsoft-prod.rpm
Retrieving https://packages.microsoft.com/config/centos/7/packages-microsoft-prod.rpm
Preparing... ################################# [100%]
Updating / installing...
1:packages-microsoft-prod-1.0-1 ################################# [100%]
虽然他们说了这么多,但是我只是最后执行了一下,最后给的命令,
没有太关注细节...(对,我相信这条命令一定把所有的依赖都处理掉了...)
2.5[正式开始.]曲折的安装SDKs之路
为什么这个步骤是"2.5"呢...因为刚开始的时候,把这个步骤忘记了,
我觉得只要我安装{ASP.NET Core runtime},会自动将这个依赖给安装上呢...
直到输入"dotnet --version",根据提示信息才发现问题,详情见下文.
[[email protected]_0_12_centos ~]# sudo yum install dotnet-sdk-3.0
//省略N多输出...
[Errno 2] No such file or directory: '/tmp/yum_save_tx.2019-11-29.13-12.0qLwqf.yumtx'
很明显报错了.搜索错误.得出以下老司机神奇代码↓任意门GoGoGo
[[email protected]_0_12_centos ~]# wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-7.repo
[[email protected]_0_12_centos ~]# yum makecache然后怀着一盒忐忑的心,再次执行了一下命令
[[email protected]_0_12_centos ~]# sudo yum install dotnet-sdk-3.0
//省略N多输出...
Installed:
dotnet-sdk-3.0.x86_64 0:3.0.101-1
Dependency Installed:
aspnetcore-targeting-pack-3.0.x86_64 0:3.0.1-1
dotnet-apphost-pack-3.0.x86_64 0:3.0.1-1
dotnet-targeting-pack-3.0.x86_64 0:3.0.0-1
netstandard-targeting-pack-2.1.x86_64 0:2.1.0-1
Complete!
3.[正式开始.runtime的抉择]Install the ASP.NET Core runtime
If you‘re installing the runtime, we suggest you install the ASP.NET Core runtime, as it includes both .NET Core and ASP.NET Core runtimes.
官网推荐直接安装{ASP.NET Core runtime},因为全啊...
[[email protected]_0_12_centos ~]# sudo yum install aspnetcore-runtime-3.0
//省略N多输出...
Installed:
aspnetcore-runtime-3.0.x86_64 0:3.0.1-1
Dependency Installed:
dotnet-host.x86_64 0:3.0.1-1 dotnet-hostfxr-3.0.x86_64 0:3.0.1-1
dotnet-runtime-3.0.x86_64 0:3.0.1-1 dotnet-runtime-deps-3.0.x86_64 0:3.0.1-1
libicu.x86_64 0:50.2-3.el7
Complete!
从上面的也看得出来,确实安装{ASP.NET Core runtime}的时候,
会自动安装其依赖{dotnet-runtime-3.0.x86_64}
4.[完美结束]打完收工
[[email protected]_0_12_centos ~]# dotnet --version
3.0.101终于Ok了...
9.[号外]中途的小意外
安装完了,看下是否安装好了,结果出现了下面的提示:
[[email protected]_0_12_centos ~]# dotnet --version
It was not possible to find any installed .NET Core SDKs
Did you mean to run .NET Core SDK commands? Install a .NET Core SDK from:
https://aka.ms/dotnet-download提示很明显,没有安装{.NET Core SDKs},可能因为我看了这句话,
If you‘re installing the runtime, we suggest you install the ASP.NET Core runtime, as it includes both .NET Core and ASP.NET Core runtimes.
理所当然觉得安装了{ASP.NET Core runtime}就万事大吉了.
后知后觉的理下丝路:
//1.安装{ASP.NET Core runtime}会安装
[
"dotnet-host.x86_64",
"dotnet-runtime-3.0.x86_64",
"libicu.x86_64"
]
//2.必须要单独安装
{
".NET Core SDKs"
}
//3.{ASP.NET Core runtime}和{".NET Core SDKs"}关系可以参考
[
"Jre",
"JDK"
]然后我就添加了步骤"2.5"
