• 国产中标麒麟Linux部署dotnet core 环境并运行项目 （二） 部署运行控制台项目

    背景
    在上一篇文章安装dotnet core，已经安装好dotnet core了。之前只是安装成功了dotnet, 输入dotnet --info，可以确认安装成功了，但是在运行代码时，还是报错了，本章记录在部署好dotnet core后，到能运行控制台程序当中的错误。

    首先将项目用vs发布一下，然后把文件放到中标麒麟的系统上，在文件夹打开终端，执行 dotnet **.dll，结果如下：

    [root@gumis02 PublishOutput]# dotnet Beyondbit.ConsoleFrameworkNetStandard.IntegrationTests.dll
Failed to load ufffd=l, error: libunwind.so.8: cannot open shared object file: No such file or directory
Failed to bind to CoreCLR at '/home/dotnet/shared/Microsoft.NETCore.App/2.0.7/libcoreclr.so'

[root@gumis02 PublishOutput]#

    错误 error : libunwind.so.8: cannot open shared object file: No such file or directory

    修复此问题的解决方案是安装 libunwind

    手动源码安装 libunwind

    libunwind的源代码现在已经托管到github上了，libunwind github 地址
    我安装的是最新版1.2.1, 输入下面命令安装：

    wget https://github.com/libunwind/libunwind/releases/download/v1.2.1/libunwind-1.2.1.tar.gz
tar -xf libunwind-1.2.1.tar.gz
cd libunwind-1.2.1
CFLAGS=-fPIC ./configure　　#添加编译参数 
make CFLAGS=-fPIC 
make CFLAGS=-fPIC install 

    安装成功后，再执行dotnet **.dll，会发现依然报错ibunwind.so.8: cannot open shared object file: No such file or directory
    在输入以下命令修复:

    [root@gumis02 dotnet]# find / -name libunwind.so.8
/home/.Trash-0/files/libunwind-1.2.1/src/.libs/libunwind.so.8
/home/NetCoreSdk/libunwind-1.2.1/src/.libs/libunwind.so.8
/usr/local/lib/libunwind.so.8
[root@gumis02 dotnet]# ln -s /usr/local/lib/libunwind.so.8 /lib64/
[root@gumis02 dotnet]# ln -s /usr/local/lib/libunwind.so.8 /lib

[root@gumis02 dotnet]# find / -name libunwind-x86_64.so.8
/home/.Trash-0/files/libunwind-1.2.1/src/.libs/libunwind-x86_64.so.8
/home/NetCoreSdk/libunwind-1.2.1/src/.libs/libunwind-x86_64.so.8
/usr/local/lib/libunwind-x86_64.so.8

[root@gumis02 dotnet]# ln -s /usr/local/lib/libunwind-x86_64.so.8 /lib64/
[root@gumis02 dotnet]# ln -s /usr/local/lib/libunwind-x86_64.so.8 /lib

    输入后，再执行dotnet **.dll，发现上面的问题已经消失。但是出现新的错误提示：

    FailFast: Couldn't find a valid ICU package installed on the system. Set the configuration flag System.Globalization.Invariant to true if you want to run with no globalization support.

[root@gumis02 PublishOutput]#

    下一步，准备修复这个错误.

    错误 Couldn't find a valid ICU package installed on the system. Set the configuration flag System.Globalization.Invariant to true if you want to run with no globalization support.

    查找资料显示，这是NET Core 全球化的模式，可见微软的文章 NET Core Globalization Invariant Mode

    摘取一段原文说明背景

    Globalization rules and the data that represents those rules frequently change, often due to country-specific policy changes (for example, changes in currency symbol, sorting behavior or time zones). Developers expect globalization behavior to always be current and for their applications to adapt to new data over time. In order to keep up with those changes, .NET Core (and the .NET Framework, too) depends on the underlying OS to keep up with these changes.

    Relying on the underlying OS for globalization data has the following benefits:

    • .NET apps have the same globalization behavior on a given OS as native apps (assuming they also rely on the OS).
    • .NET apps do not have to carry this data.
    • The .NET team doesn't have to maintain this data themselves (it's very expensive to do this!).

    Globalization support has the following potential challenges for applications:

    • Different behavior across OSes (and potentially OS versions).
    • Installing/carrying the ICU package on Linux (~28 MB).

    Note: On Linux, .NET Core relies on globalization data from ICU. For example, .NET Core Linux Docker images install this component. Globalization data is available on Windows and macOS as part of their base installs.

    上文提到依赖 ICU Package，可点击链接去查看。

    有两种解决方案：

    1. 在runtimeconfig.json中添加以下配置即可，不想纠结原理的就使用这种方式即可：
        "configProperties": {
      "System.Globalization.Invariant": true
    }

    完整的在runtimeconfig.json 如下：

    {
  "runtimeOptions": {
    "tfm": "netcoreapp2.0",
    "framework": {
      "name": "Microsoft.NETCore.App",
      "version": "2.0.0"
    },
   "configProperties": {
      "System.Globalization.Invariant": true
    }
  }
}

    注意
    这种方式，证明了是可以解决问题的，但是他开启了Globalization.Invariant Mode 模式，在简单的应用下，程序可以正常运行，但是在遇到复杂的应用很有可能会遇到一个异常，System.ArgumentNullException: SafeHandle cannot be null，见我正式项目的运行结果，这个异常在github上有很多人提到，如：

    我的测试项目就是用了log4net导致的，目前net corefx团队收到了反馈已经在着手解决了。要想终极解决此问题，需要用以下第二种方式来解决，安装 ICU Package模块。

    1. 安装ICU Package

    ICU Package

    我们使用源码的方式安装icu. 我选择的是59.1版本，输入以下命令：

    wget http://download.icu-project.org/files/icu4c/59.1/icu4c-59_1-src.tgz 
tar -xzvf icu4c-59_1-src.tgz
cd icu/source
./configure --prefix=/usr/local/icu

make 
make install

    参看是否安装成功：

    [root@gumis02 ~]# icu-config --version
59.1
[root@gumis02 ~]# icuinfo
icuinfo: error while loading shared libraries: libicutu.so.59: cannot open shared object file: No such file or directory

    看到安装成功了，但是查看具体信息会提示缺少 libicutu.so.59，其他缺少的dll，同样处理。
    输入以下命令查找，并映射so文件：

    [root@gumis02 ~]# find / -name libicutu.so.59
/home/NetCoreSdk/icu/source/lib/libicutu.so.59
/home/NetCoreSdk/icu2/source/lib/libicutu.so.59
/usr/lib/libicutu.so.59
/usr/local/icu/lib/libicutu.so.59

[root@gumis02 ~]# ln -s /usr/local/icu/lib/libicutu.so.59 /lib64/
[root@gumis02 ~]# ln -s /usr/local/icu/lib/libicui18n.so.59 /lib64/
[root@gumis02 ~]# ln -s /usr/local/icu/lib/libicuuc.so.59 /lib64/
[root@gumis02 ~]# ln -s /usr/local/icu/lib/libicudata.so.59 /lib64/
[root@gumis02 ~]# ln -s /usr/local/icu/lib/libicudata.so.59 /lib64/

ICU Initialization returned: U_ZERO_ERROR

    参考：

    install ICU-61.1
    安装完成后，再测试正式的项目，执行成功了，数据插入到数据库了。

    运行测试

    HelloWorld 项目

    采用配置了 runtimeconfig.json中添加以下配置

        "configProperties": {
      "System.Globalization.Invariant": true
    }

    HelloWorld程序运行测试：

    Microsoft .NET Core Shared Framework Host

    正式控制台项目

    在runtimeconfig.json中添加以下配置即可，不想纠结原理的就使用这种方式即可：

        "configProperties": {
      "System.Globalization.Invariant": true
    }

    上面的这种方式，我使用helloworld程序是能正常运行的，但是在正式的项目中，用到了log4net，运行的话，会报其他的错误：

    可以看到错误的调用堆栈，是由log4net运行出来的，这个很有可能是里面需要增加全局资源文件，因为看到了System.Globalization命名空间，不过呢，已经能看到了正常的net 错误堆栈，可以证明dotnet 已经在中标麒麟的操作系统上能运行了。

    这个异常产生的原因我在上面已经说明了，要解决这个问题，不能开启Globalization.Invariant，必须讲他设置成false，同时安装ICU Packet解决
    在runtimeconfig.json中添加以下配置即可，不想纠结原理的就使用这种方式即可：

        "configProperties": {
      "System.Globalization.Invariant": false
    }

    执行结果：

    [root@gumis02 PublishOutput]# dotnet Beyondbit.ConsoleFrameworkNetStandard.IntegrationTests.dll
用户插入成功
[root@gumis02 PublishOutput]#

    dotnet core 2.0 在真实项目上，还有很多的未知，还等待我去解决和探索。 Keep going.

    总结：
    经过一个星期的摸爬滚打终于在中标麒麟Linux系统上成功的运行了dotnet core 正式的项目，而不是helloworld程序。心力交瘁中也收获了很多东西，在这一个星期中，我一个linux盲，也掌握了很多linux命令，如:mkdir,ln, find,ll,ldd 等等。

    当然用了一个星期的时间，主要还是自己两方面的问题：

    1. 对linux不熟悉，基本是linux盲
    2. 对net core 底层的编译知识还不熟悉，在摸索当中

    后续还要加强两方面的学习，学无止境

    后续

    成功的是控制台程序，下一步开始把做好的dotnet core web api + 前端 vuejs项目部署到麒麟系统上，我预计到又是一段打怪路程，通关后，我会继续将通关记录分享出来。

    最后晒下截图：
