如何解决未找到python解释器时,Ansible播放挂起冻结
如果有人想尝试,可以重现此问题。
当目标主机“ 10.9.88.205”未安装python时,Ansible挂起。
我从ansible到目标主机成功建立了ssh连接,如下所示:
ansible-host# ssh root@10.9.88.205
下面是我的剧本:
- name: Play 2- Configure Source nodes
hosts: all
user: root
ignore_errors: yes
gather_facts: false
tasks:
- name: Get HTTPD userid on server
raw: id mwweb || id webadm || ls -ld /web
- name: Get OHS userid on server
raw: id mwweb
下面是我运行剧本的方式
[ansibleuser@ansiblehost checkssh]$ ansible-playbook -i 10.9.88.205,-f 5 testpython.yml -vvvv
ansible-playbook 2.9.4
config file = /etc/ansible/ansible.cfg
configured module search path = [u'/home/ansibleuser/.ansible/plugins/modules',u'/usr/share/ansible/plugins/modules']
ansible python module location = /usr/lib/python2.7/site-packages/ansible
executable location = /usr/bin/ansible-playbook
python version = 2.7.5 (default,Sep 26 2019,13:23:47) [GCC 4.8.5 20150623 (Red Hat 4.8.5-39)]
Using /etc/ansible/ansible.cfg as config file
setting up inventory plugins

它仅在打印TASK [Get HTTPD userid on server]
后挂起,并且从未完成。
所有未安装python且可通过ssh访问的IP都会遇到这种情况。
下面是我的烦人的版本。
ansible --version
ansible 2.9.4
config file = /etc/ansible/ansible.cfg
configured module search path = [u'/home/.ansible/plugins/modules',u'/usr/share/ansible/plugins/modules']
ansible python module location = /usr/lib/python2.7/site-packages/ansible
executable location = /usr/bin/ansible
python version = 2.7.5 (default,13:23:47) [GCC 4.8.5 20150623 (Red Hat 4.8.5-39)]
然后,我从ansible输出中手动尝试了ssh
命令,该命令也冻结了。请参阅下面的ssh输出:
[ansibleuser@ansiblehostcheckssh]$ ssh -vvv -C -o ControlMaster=auto -o ControlPersist=60s -o 'IdentityFile="/app/ssh_keys/id_rsa"' -o KbdInteractiveAuthentication=no -o PreferredAuthentications=gssapi-with-mic,publickey -o PasswordAuthentication=no -o 'User="root"' -o ConnectTimeout=10 -o StrictHostKeyChecking=no -o ControlPath=/home/ansibleuser/.ansible/cp/6abdc12511 -tt 10.9.88.205 'id mwweb || id webadm || ls -ld /web'

我进一步调查并确定了是否从ssh中删除了 -o ControlPath=/home/ansibleuser/.ansible/cp/6abdc12511 -tt
,表明ansible构造了ssh可以正常工作并且不会挂起。
因此,下面手动构造的ssh
可以正常工作。
ssh -vvv -C -o ControlMaster=auto -o ControlPersist=60s -o 'IdentityFile="/app/ssh_keys/id_rsa"' -o KbdInteractiveAuthentication=no -o PreferredAuthentications=gssapi-with-mic,publickey -o PasswordAuthentication=no -o 'User="root"' -o ConnectTimeout=10 -o StrictHostKeyChecking=no 10.9.88.205 'id mwweb || id webadm || ls -ld /web'
您能建议我如何使自己不挂死并继续执行下一个任务吗?
