centos 6.5 安装dotnet core 2.2

2024-04-28 07:59•移动端•阅读 643

.net core 官网地址

https://dotnet.microsoft.com/download

本次安装版本为.net core SDK v2.2.101

1、查看系统版本, 升级系统基本lib库

[root@test ~]# cat /etc/redhat-release
CentOS release 6.5 (Final)
[root@test ~]# yum update     //可以执行此步骤，减少后面lib库依赖的痛苦。

2、下载.net core SDK v2.2.101 安装文件,并解压到指定目录

[root@test ~]#wget https://download.visualstudio.microsoft.com/download/pr/80e1d007-d6f0-402f-b047-779464dd989b/9ae5e2df9aa166b720bdb92d19977044/dotnet-sdk-2.2.101-linux-x64.tar.gz -P /usr/local/src
[root@test ~]#cd /usr/local/src
[root@test src]#mkdir -p /usr/local/dotnetcore
[root@test src]#tar -zxf dotnet-sdk-2.2.101-linux-x64.tar.gz -C /usr/local/dotnetcore

3、添加net core环境变量

[root@test src]# vi /etc/profile

增加以下几行

#set dotnet core
export DOTNET_ROOT=/usr/local/dotnetcore
export PATH=$PATH:$DOTNET_ROOT

#生效环境变量

[root@test src]#source /etc/profile

4、查看dotnet 版本

[root@test src]# dotnet --version
dotnet: /usr/lib64/libstdc++.so.6: version `GLIBCXX_3.4.18' not found (required by dotnet)
dotnet: /usr/lib64/libstdc++.so.6: version `GLIBCXX_3.4.17' not found (required by dotnet)
dotnet: /usr/lib64/libstdc++.so.6: version `CXXABI_1.3.5' not found (required by dotnet)
dotnet: /usr/lib64/libstdc++.so.6: version `GLIBCXX_3.4.14' not found (required by dotnet)
dotnet: /usr/lib64/libstdc++.so.6: version `GLIBCXX_3.4.15' not found (required by dotnet)

5、OMG，报错了。接下来才是重点，一步步解决到错误，首先查看GCC版本和默认动态库

5.1查看默认的gcc版本

[root@test src]# gcc --version
gcc (GCC) 4.4.7 20120313 (Red Hat 4.4.7-23)
Copyright (C) 2010 Free Software Foundation, Inc.
This is free software; see the source for copying conditions.  There is NO
warranty; not even for MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.

5.2查看默认动态库

[root@test src]# strings /usr/lib64/libstdc++.so.6 | grep GLIBC
GLIBCXX_3.4
GLIBCXX_3.4.1
GLIBCXX_3.4.2
GLIBCXX_3.4.3
GLIBCXX_3.4.4
GLIBCXX_3.4.5
GLIBCXX_3.4.6
GLIBCXX_3.4.7
GLIBCXX_3.4.8
GLIBCXX_3.4.9
GLIBCXX_3.4.10
GLIBCXX_3.4.11
GLIBCXX_3.4.12
GLIBCXX_3.4.13
GLIBC_2.2.5
GLIBC_2.3
GLIBC_2.4
GLIBC_2.3.2
GLIBCXX_FORCE_NEW
GLIBCXX_DEBUG_MESSAGE_LENGTH
##低版本的gcc 不支持C++11的特性没有 GLIBCXX_3.4.14\GLIBCXX_3.4.15\GLIBCXX_3.4.17\GLIBCXX_3.4.18

此时有两种解决办法，首先，从其他地方拷贝一个libstdc++.so.6.0.19版本，或者其他高版本

上传文件到/usr/lib64 目录下

ln -sf libstdc++.so.6.0.19 libstdc++.so.6

此时在查看

[root@test src]# strings /usr/lib64/libstdc++.so.6 | grep GLIBC

已经支持C++11 特性了。！！！

我上传一下我的编译好的libstdc++.so.6.0.19 文件，

链接：https://pan.baidu.com/s/1vgojWen8FNmlXaIupLcQjQ

提取码：7hfz

或者自己编译gcc，下面步骤是编译gcc 4.8.5

5.3因为在centos 7 安装直接安装官方文档即可，默认centos7 gcc版本是4.8.5 ，所以在此也选择升级到版本为4.8.5

GCC官网链接：https://gcc.gnu.org/

5.3.1下载gcc 4.8.5 安装包并解压

[root@test src]#wget http://mirror.linux-ia64.org/gnu/gcc/releases/gcc-4.8.5/gcc-4.8.5.tar.gz
[root@test src]#tar -zxf gcc-4.8.5.tar.gz

5.3.2 检查链接gcc升级依赖包mpfr-2.4.2、gmp-4.3.2、mpc-0.8.1

[root@test src]#cat gcc-4.8.5/contrib/download_prerequisites
#! /bin/sh

# Download some prerequisites needed by gcc.
# Run this from the top level of the gcc source tree and the gcc
# build will do the right thing.

MPFR=mpfr-2.4.2
GMP=gmp-4.3.2
MPC=mpc-0.8.1

wget ftp://gcc.gnu.org/pub/gcc/infrastructure/$MPFR.tar.bz2 || exit 1
tar xjf $MPFR.tar.bz2 || exit 1
ln -sf $MPFR mpfr || exit 1

wget ftp://gcc.gnu.org/pub/gcc/infrastructure/$GMP.tar.bz2 || exit 1

ln -sf $GMP gmp || exit 1

wget ftp://gcc.gnu.org/pub/gcc/infrastructure/$MPC.tar.gz || exit 1
tar xzf $MPC.tar.gz || exit 1
ln -sf $MPC mpc || exit 1

rm $MPFR.tar.bz2 $GMP.tar.bz2 $MPC.tar.gz || exit 1

5.3.3 按照脚本指示下载、解压、链接

[root@test src]# wget ftp://gcc.gnu.org/pub/gcc/infrastructure/mpfr-2.4.2.tar.bz2
[root@test src]# wget ftp://gcc.gnu.org/pub/gcc/infrastructure/gmp-4.3.2.tar.bz2
[root@test src# wget ftp://gcc.gnu.org/pub/gcc/infrastructure/mpc-0.8.1.tar.gz

查看下载的文件

[root@test src]# ls *tar.*
gmp-4.3.2.tar.bz2  mpc-0.8.1.tar.gz  mpfr-2.4.2.tar.bz2

[root@test src]# tar xjf mpfr-2.4.2.tar.bz2
[root@test src]# tar xjf gmp-4.3.2.tar.bz2
[root@test src]# tar -xzf mpc-0.8.1.tar.gz
[root@test src]# ln -sf mpfr-2.4.2 gcc-4.8.5/mpfr
[root@test src]# ln -sf gmp-4.3.2 gcc-4.8.5/gmp
[root@test src]# ln -sf mpc-0.8.1 gcc-4.8.5/mpc

5.3.4生成编译文件

[root@test src]cd gcc-4.8.5
[root@test gcc-4.8.5]# ./configure -enable-checking=release -enable-languages=c,c++ -disable-multilib
##如果没有报错，接着执行make ，如果多核心可以make -j4 ,过程比较长，可以看个小黄片，泡个咖啡等上半个小时。

[root@test gcc-4.8.5]#make -j4

[root@test gcc-4.8.5]#make install

5.3.5安装完GCC，检查一下

[root@test src]# ls /usr/local/bin| grep gcc
gcc
gcc-ar
gcc-nm
gcc-ranlib
x86_64-unknown-linux-gnu-gcc
x86_64-unknown-linux-gnu-gcc-4.8.5
x86_64-unknown-linux-gnu-gcc-ar
x86_64-unknown-linux-gnu-gcc-nm
x86_64-unknown-linux-gnu-gcc-ranlib

##此时证明安装gcc成功

[root@test src]#cp /usr/local/lib64/libstdc++.so.6.0.19 /usr/lib64/

[root@test src]#cd /usr/lib64/

[root@test lib64]#rm -f libstdc++.so.6

[root@test lib64]#ln -s libstdc++.so.6.0.19 libstdc++.so.6

5.3.6 再次检查dotnet core 版本

[root@test gcc-4.8.5]# dotnet --version
Failed to load  error: /lib64/libc.so.6: version `GLIBC_2.14' not found (required by /usr/local/dotnetcore/host/fxr/2.2.0/libhostfxr.so)
The library libhostfxr.so was found, but loading it from /usr/local/dotnetcore/host/fxr/2.2.0/libhostfxr.so failed
  - Installing .NET Core prerequisites might help resolve this problem.

###又提示报错，需要GLIBC_2.14支持

6.查看系统glibc支持的版本

[root@test src]# strings /lib64/libc.so.6 |grep GLIBC_
GLIBC_2.2.5
GLIBC_2.2.6
GLIBC_2.3
GLIBC_2.3.2
GLIBC_2.3.3
GLIBC_2.3.4
GLIBC_2.4
GLIBC_2.5
GLIBC_2.6
GLIBC_2.7
GLIBC_2.8
GLIBC_2.9
GLIBC_2.10
GLIBC_2.11
GLIBC_2.12
GLIBC_PRIVATE

##可以看到最高的版本是GLIBC_2.12,没有GLIBC_2.14。我们在此解决一下

6.1 下载glibc

[root@test src]# cd /usr/local/lib
[root@test lib]# wget -c http://ftp.gnu.org/gnu/glibc/glibc-2.14.tar.gz
[root@test lib]# tar -zxf glibc-2.14.tar.gz
[root@test lib]# cd glibc-2.14

6.2 在glibc源码目录建立构建目录,并make 安装

[root@test glibc-2.14]#mkdir build && cd build
[root@test build]# ../configure --prefix=/opt/glibc-2.14
[root@test build]#make j4

[root@test build]#make j4 localedata/install-locales     //如果不执行这一步，直接就导致了后面locale的设置问题

[root@test build]#make j4 install

6.3配置

[root@test glibc-2.14]cp /etc/ld.so.c* /opt/glibc-2.14/etc/
[root@test glibc-2.14]ln -sf /opt/glibc-2.14/lib/libc-2.14.so /lib64/libc.so.6

注意

删除libc.so.6之后可能导致系统命令不可用的情况, 可使用如下方法解决:

如果上述更新失败可使用如下命令还原:

此项是系统升级前的版本

6.4查看版本库支持

[root@test build]# strings /lib64/libc.so.6 |grep GLIBC_
GLIBC_2.2.5
GLIBC_2.2.6
GLIBC_2.3
GLIBC_2.3.2
GLIBC_2.3.3
GLIBC_2.3.4
GLIBC_2.4
GLIBC_2.5
GLIBC_2.6
GLIBC_2.7
GLIBC_2.8
GLIBC_2.9
GLIBC_2.10
GLIBC_2.11
GLIBC_2.12
GLIBC_2.13
GLIBC_2.14
GLIBC_PRIVATE


##已经支持 GLIBC_2.14

6.5 再次检查dotnet core 版本

[root@test build]#dotnet --version
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.

   at System.Environment.FailFast(System.String)

   at System.AppDomain.InitializeCompatibilityFlags()

   at System.AppDomain.Setup(System.Object)

###又提示缺少ICU，真是一波三折啊

7.安装ICU，使用源码的方式安装icu. 我选择的是59.1版本，安装59.1可能有报错信息，如下：

make[1]: *** [stubdata.o] Error 1

make[1]: Leaving directory `/root/icu/source/stubdata'

make: *** [all-recursive] Error 2

换成56.1版本可以解决下载地址http://download.icu-project.org/files/icu4c/56.1/icu4c-56_1-src.tgz

安装过程一样，软链接创建时候请注意不要直接copy

但是本次使用59.1安装

[root@test build]# cd /usr/local/src/
[root@test src]# wget http://download.icu-project.org/files/icu4c/59.1/icu4c-59_1-src.tgz
[root@test src]#tar -xzvf icu4c-59_1-src.tgz
[root@test src]#cd icu/source
[root@test source]#./configure --prefix=/usr/local/icu
[root@test source]#gmake  && make install

参看是否安装成功：
[root@test source]#cd /usr/local/icu/bin
[root@test bin]#./icu-config --version
59.1

[root@test bin]#./icuinfo
./icuinfo: error while loading shared libraries: libicutu.so.59: cannot open shared object file: No such file or directory

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。

[root@test bin]# find / -name libicutu.so.59
/lib64/libicutu.so.59
/usr/local/icu/lib/libicutu.so.59

8.再次执行dotnet --version

[root@test bin]# dotnet --version
2.2.101
