为什么我不能重建工作？

Question

我有一个jenkins服务器，jenkins从2.220升级到2.387.1，所有插件都升级了。

当我重建工作时，它给了我这样的产出：

Started by user abc
Running as SYSTEM
Building in workspace /var/lib/jenkins/workspace/DEF_GW_ENROLL_USER_PREPROD
[DEF_GW_ENROLL_USER_PREPROD] $ /bin/bash -x /tmp/jenkins81696621479514690.sh
+ export SSH_CONF=/var/lib/jenkins/.ssh/config/ssh_config_preprod-ue1
+ SSH_CONF=/var/lib/jenkins/.ssh/config/ssh_config_preprod-ue1
+ echo PREPROD
PREPROD
+ export targets=batch-host
+ targets=batch-host
+ for host in '$targets'
+ ssh -F /var/lib/jenkins/.ssh/config/ssh_config_preprod-ue1 batch-host 'sudo python add_user_pastdated.py web.pre.domain.com abc1234 1 target.internal.domain.com false AUTHSERVER_V1R1 KPREHA_002 8  PST true'
ssh_exchange_identification: Connection closed by remote host
Build step 'Execute shell' marked build as failure
[WS-CLEANUP] Deleting project workspace...[WS-CLEANUP] Skipped based on build state FAILURE
Finished: FAILURE

我尝试做一个手动ssh，通过将配置文件从/var/lib/jenkins/.ssh/config/ssh_config_preprod-ue1复制到~/.ssh/，然后运行ssh命令，成功地建立了连接，我能够进入服务器。

jenkins.log是空的，ssh插件没有显示错误消息，所以我现在没有任何线索。

根本原因是什么？

Answer 1

您可以做的测试很少:检查文件权限/var/lib/jenkins/.ssh/config/ssh_config_preprod-ue1和相应的私钥，然后所有权，它必须由Jenkins用户拥有，必要时使用chown。

sudo chown jenkins:jenkins /var/lib/jenkins/.ssh/config/ssh_config_preprod-ue1
sudo chown jenkins:jenkins /var/lib/jenkins/.ssh/id_rsa (or the corresponding private key file)

还请检查ssh配置/var/lib/jenkins/.ssh/config/ssh_config_preprod-ue1。

尝试以Jenkins用户的身份手动建立SSH连接

sudo su - jenkins
ssh -F /var/lib/jenkins/.ssh/config/ssh_config_preprod-ue1 batch-host

您还可以查看远程主机日志/var/log/auth.log (或/var/log/secure )。
