ansible读写系统默认变量

本文主要是介绍ansible读写系统默认变量,对大家解决编程问题具有一定的参考价值,需要的程序猿们随着小编来一起学习吧!

而且此处我们可以写成变量的形式,首先,我们用ansible的setup模块取出VCPU的表示
[root@ceshi ansible]# ansible -i hosts ceshi -m setup |grep "processor"
"ansible_processor": [
"ansible_processor_cores": 1,
"ansible_processor_count": 4,
"ansible_processor_threads_per_core": 1,
"ansible_processor_vcpus": 4,

然后修改 worker_processes auto; ------> worker_processes {{ ansible_processor_vcpus*2 }}; ###nginx进程数乘以2
修改完模板后,由于我们之前都已经装过包了,所以我们需要再次修改我们的playbook
---
- hosts: ceshi
remote_user: root

tasks:
- name: install package
yum: name=nginx
- name: copy template
template: src=nginx.conf.j2 dest=/etc/nginx/nginx.conf
notif: restart service
- name: start service
service: name=nginx state=started enabled=yes
handlers:
- name: restart service
service: name=nginx state=restarted
