Gitlab CI - SSH 权限被拒绝（公钥、密码）

Question

我一直在尝试为我的项目设置 CD。 我的 Gitlab CI runner 和我的项目将在同一台服务器上。 我已经关注了https://docs.gitlab.com/ee/ci/examples/deployment/composer-npm-deploy.html但我一直收到SSH Permission denied (publickey,password). 错误。 我的所有变量、私钥和其他变量都在项目设置中正确设置。

我已经使用没有密码的ssh-keygen -t rsa -C "my.email@example.com" -b 4096命令创建了我的 ssh 密钥，并使用~/.ssh/id_rsa文件的内容设置了我的PRODUCTION_PRIVATE_KEY变量。

这是我的gitlab-ci.yml ：

stages:
  - deploy

deploy_production:
  stage: deploy
  image: tetraweb/php
  before_script:
    - 'which ssh-agent || ( apt-get update -y && apt-get install openssh-client -y )'
    - eval $(ssh-agent -s)
    - ssh-add <(echo "$PRODUCTION_PRIVATE_KEY")
    - mkdir -p ~/.ssh
    - echo -e "Host *\n\tStrictHostKeyChecking no\n\n" > ~/.ssh/config
    - apt-get install rsync
  script:
    - ssh $PRODUCTION_SERVER_USER@$PRODUCTION_SERVER
    - hostname
  only:
    - master

这是 Gitlab CI runner 的输出：

提前致谢。

Answer 1

您需要将公钥添加到服务器，以便将其识别为身份验证密钥。 也就是说，将与您正在使用的私钥对应的公钥内容粘贴到$PRODUCTION_SERVER上的~/.ssh/authorized_keys 。

Answer 2

这是对我有用的脚本：

before_script:
                - 'which ssh-agent || ( apt-get update -y && apt-get install openssh-client -y )'
                - mkdir -p ~/.ssh
                - echo "$SSH_PRIVATE_KEY" | tr -d '\r' > ~/.ssh/id_rsa
                - chmod 700 ~/.ssh/id_rsa
                - eval "$(ssh-agent -s)"
                - ssh-add ~/.ssh/id_rsa
                - ssh-keyscan -t rsa 64.227.1.160 > ~/.ssh/known_hosts
                - echo -e "Host *\n\tStrictHostKeyChecking no\n\n" > ~/.ssh/config
                - chmod 644 ~/.ssh/known_hosts

而且我还必须取消对变量的保护。

Answer 3

还有一点很重要... ~/.ssh/authorized_keys 文件的权限应该是 600。

Answer 4

以下可以交替使用

some_stage:
        - eval $(ssh-agent -s)
        - cd ~
        - touch id.rsa
        - echo "$SSH_PRIVATE_KEY" > id.rsa
        - chmod 700 id.rsa
        - ssh -o StrictHostKeyChecking=no -i id.rsa $SSH_USER@$SERVER
