使用 Ansible 在服务器上执行 shell 脚本

Question

I have to run shell script on multiple server using Ansible. I am using following code.

-name: start script
 hosts: list_of_host
 become: yes
 gather_facts: no
 role:
   - startscript

in startscript i have below code...

-name: start script
 shell: /bin/bash /home/ansible/test_script.sh
 chnaged_when: false

Test_script is forever running process on sever. so when i am executing this command it's not coming out from that server. I need that it should start script on server and come out and go to another server to start script.

Answer 1

If /home/ansible/test_script.sh is "forever running", you should convert that to a service and start it via systemctl.

Obviously ansible would wait for the shell: command to complete..

shell should not be used for "forever running" scripts.

You can also start the /home/ansible/test_script.sh by starting a screen and executing the script within it, so it continues to run after ansible exits,

or you can try and push that script to background execution by adding & at the end of your shell: command, as well as prefixing the command with nohup so it is not terminated when ansible's ssh connection disconnects
