Enable VS Code Remote-SSH on CentOS 7

License: MIT CentOS 7 VS Code

🚀 Install glibc 2.28 and libstdc++ on CentOS 7 for VS Code Remote-SSH compatibility

한국어 | English

한국어

📋 개요

CentOS 7은 2024년 6월 30일에 **EOL(End of Life)**을 맞이했으며, 기본 glibc 버전(2.17)이 너무 낮아 최신 VS Code Remote-SSH 서버가 작동하지 않습니다.

이 프로젝트는 CentOS 7에서 glibc 2.28과 **libstdc++.so.6 (GLIBCXX_3.4.21+)**을 설치하여 VS Code Remote-SSH를 사용할 수 있게 해주는 자동화 스크립트입니다.

⚠️ 해결하는 문제

문제 1: CentOS 7 EOL로 인한 저장소 접근 불가

Could not resolve host: mirrorlist.centos.org

문제 2: glibc 버전이 낮아 VS Code 서버 실행 불가

version `GLIBC_2.28' not found

문제 3: libstdc++ 버전이 낮아 node 실행 불가

version `GLIBCXX_3.4.21' not found
version `CXXABI_1.3.9' not found

✨ 특징

  • ✅ 완전 자동화: 한 번의 실행으로 모든 설정 완료
  • ✅ 멱등성 보장: 재실행 가능 (이미 설치된 구성 요소는 건너뜀)
  • ✅ 안전성: 에러 처리 및 Fallback 로직 구현
  • ✅ EOL 대응: vault.centos.org로 자동 전환
  • ✅ 최신 라이브러리: glibc 2.28 + libstdc++ (gcc 9.3.0)

🔧 설치 방법

1단계: 스크립트 다운로드

# GitHub에서 다운로드
wget https://raw.githubusercontent.com/YourBestDeveloper/vscode-remote-ssh-centos7/main/enable-remote-ssh-centos7.sh

# 또는 curl 사용
curl -O https://raw.githubusercontent.com/YourBestDeveloper/vscode-remote-ssh-centos7/main/enable-remote-ssh-centos7.sh

2단계: 실행

# 실행 권한 부여
chmod +x enable-remote-ssh-centos7.sh

# root로 실행
sudo bash enable-remote-ssh-centos7.sh

3단계: VS Code Remote-SSH 연결

VS Code에서 Remote-SSH로 연결하면 자동으로 작동합니다! 🎉

⏱️ 소요 시간

프로세서 성능에 따라 15-25분 정도 소요됩니다.

🛠️ 기술적 세부사항

설치되는 구성 요소

  1. glibc 2.28

    • 설치 위치: /opt/glibc-2.28
    • VS Code 서버가 요구하는 최신 glibc

  2. libstdc++.so.6 (gcc 9.3.0)

    • 설치 위치: /opt/rh/devtoolset-9/root/usr/lib64
    • GLIBCXX_3.4.21+, CXXABI_1.3.9+ 지원

  3. devtoolset-9

    • gcc 9.3.1
    • make 4.2.1
    • g++ 9.3.1

환경변수 설정

자동으로 다음 파일에 환경변수가 설정됩니다:

  • /etc/profile.d/vscode-glibc.sh
  • /etc/environment
export VSCODE_SERVER_CUSTOM_GLIBC_LINKER=/opt/glibc-2.28/lib/ld-2.28.so
export VSCODE_SERVER_CUSTOM_GLIBC_PATH=/opt/glibc-2.28/lib:/opt/rh/devtoolset-9/root/usr/lib64:/usr/lib64:/lib64
export VSCODE_SERVER_PATCHELF_PATH=/bin/patchelf
export LD_LIBRARY_PATH=/opt/rh/devtoolset-9/root/usr/lib64:${LD_LIBRARY_PATH}

📦 스크립트 구조

1. Root 권한 체크
2. CentOS 7 EOL 처리 (vault.centos.org 전환)
3. EPEL 저장소 활성화
4. 필수 패키지 설치
   4a. devtoolset-9 설치
   4b. libstdc++.so.6 빌드
5. glibc 2.28 빌드
6. 환경변수 설정
7. 완료

🔍 문제 해결

VS Code 연결이 여전히 실패하는 경우

# 환경변수 확인
cat /etc/profile.d/vscode-glibc.sh

# VS Code 서버 프로세스 종료 후 재시도
pkill -9 -f '.vscode-server'

# 스크립트 재실행
sudo bash enable-remote-ssh-centos7.sh

특정 구성 요소만 재빌드

# libstdc++ 파일 삭제 후 재실행
sudo rm -f /opt/rh/devtoolset-9/root/usr/lib64/libstdc++.so.6*
sudo bash enable-remote-ssh-centos7.sh

# glibc 삭제 후 재실행
sudo rm -rf /opt/glibc-2.28
sudo bash enable-remote-ssh-centos7.sh

⚠️ 주의사항

  • 이 스크립트는 시스템 glibc를 교체하지 않습니다 (안전)
  • /opt/glibc-2.28에 별도로 설치됩니다
  • 기존 시스템 라이브러리는 영향받지 않습니다
  • VS Code Remote-SSH 전용 설정입니다

📋 Overview

CentOS 7 reached EOL (End of Life) on June 30, 2024, and its default glibc version (2.17) is too old for the latest VS Code Remote-SSH server.

This project provides an automated script to install glibc 2.28 and libstdc++.so.6 (GLIBCXX_3.4.21+) on CentOS 7, enabling VS Code Remote-SSH functionality.

⚠️ Problems Solved

Problem 1: CentOS 7 EOL - Repository Access Denied

Could not resolve host: mirrorlist.centos.org

Problem 2: glibc Version Too Low

version `GLIBC_2.28' not found

Problem 3: libstdc++ Version Too Low

version `GLIBCXX_3.4.21' not found
version `CXXABI_1.3.9' not found

✨ Features

  • ✅ Fully Automated: One-command setup
  • ✅ Idempotent: Safe to re-run (skips already installed components)
  • ✅ Safe: Comprehensive error handling and fallback logic
  • ✅ EOL Ready: Automatically switches to vault.centos.org
  • ✅ Modern Libraries: glibc 2.28 + libstdc++ (gcc 9.3.0)

🔧 Installation

Step 1: Download Script

# Download from GitHub
wget https://raw.githubusercontent.com/YourBestDeveloper/vscode-remote-ssh-centos7/main/enable-remote-ssh-centos7.sh

# Or use curl
curl -O https://raw.githubusercontent.com/YourBestDeveloper/vscode-remote-ssh-centos7/main/enable-remote-ssh-centos7.sh

Step 2: Run

# Make executable
chmod +x enable-remote-ssh-centos7.sh

# Run as root
sudo bash enable-remote-ssh-centos7.sh

Step 3: Connect with VS Code Remote-SSH

Connect via Remote-SSH in VS Code - it will work automatically! 🎉

⏱️ Execution Time

Approximately 15-25 minutes depending on your processor performance.

🛠️ Technical Details

Installed Components

  1. glibc 2.28

    • Location: /opt/glibc-2.28
    • Required by VS Code server

  2. libstdc++.so.6 (gcc 9.3.0)

    • Location: /opt/rh/devtoolset-9/root/usr/lib64
    • Supports GLIBCXX_3.4.21+, CXXABI_1.3.9+

  3. devtoolset-9

    • gcc 9.3.1
    • make 4.2.1
    • g++ 9.3.1

Environment Variables

Automatically configured in:

  • /etc/profile.d/vscode-glibc.sh
  • /etc/environment
export VSCODE_SERVER_CUSTOM_GLIBC_LINKER=/opt/glibc-2.28/lib/ld-2.28.so
export VSCODE_SERVER_CUSTOM_GLIBC_PATH=/opt/glibc-2.28/lib:/opt/rh/devtoolset-9/root/usr/lib64:/usr/lib64:/lib64
export VSCODE_SERVER_PATCHELF_PATH=/bin/patchelf
export LD_LIBRARY_PATH=/opt/rh/devtoolset-9/root/usr/lib64:${LD_LIBRARY_PATH}

🔍 Troubleshooting

VS Code Connection Still Fails

# Check environment variables
cat /etc/profile.d/vscode-glibc.sh

# Kill VS Code server and retry
pkill -9 -f '.vscode-server'

# Re-run script
sudo bash enable-remote-ssh-centos7.sh

Rebuild Specific Components

# Rebuild libstdc++
sudo rm -f /opt/rh/devtoolset-9/root/usr/lib64/libstdc++.so.6*
sudo bash enable-remote-ssh-centos7.sh

# Rebuild glibc
sudo rm -rf /opt/glibc-2.28
sudo bash enable-remote-ssh-centos7.sh

⚠️ Important Notes

  • This script does NOT replace system glibc (safe)
  • Installs separately in /opt/glibc-2.28
  • Existing system libraries remain untouched
  • Specific to VS Code Remote-SSH
