ansible 用变量简单渲染nginx配置文件
1.首先在ansible上形成vhost.fact cat books.txtw ip1 dev 8021 8688 api
w ip2 dev 8021 8688 api
w是tomcat应用名称，api是域名名称
nginx.py
#!/usr/bin/env python
# -*- coding: utf-8 -*-
import ConfigParser
import string, os, sys
def ynameconf():
sfile = 'books.txt'
inventory = {}
with open(sfile, 'rb') as f:
for i in f.readlines():
ip = i.strip().split()
yname = i.strip().split()# 域名
if not yname in inventory:
inventory = []
inventory.append(ip)
return inventory
def ynameParser():
cf = ConfigParser.ConfigParser()
ynameyname=ynameconf()
for k,v in ynameyname.iteritems():
cf.add_section('general')
cf.set("general", "pro_dir", k)
cf.set("general", "ip1", v)
cf.set("general", "ip2", v)
# cf.set(k, ','.join(v))
cf.write(open("vhost.fact", "w"))
ynameP=ynameParser()
生成的vhost.fact的样子
pro_dir = api
ip1 = ip1
ip2 = ip2
还有很多问题
1.假如有三台以上机器怎么处理
2.多个域名怎么同时处理，搞到我想到了协程
2.写yml文件，就几行
mkdir -p /etc/ansible/nginx
├── hosts
├── roles
│ └── vhost
│ ├── default
│ ├── files
│ ├── handlers
│ │ └── main.yml
│ ├── meta
│ ├── tasks
│ │ ├── install.yml
│ │ └── main.yml
│ ├── templates
│ │ ├── set.conf
│ │ └── vhost.conf
│ └── vars
└── vhost.yml
主要tasks/install.yml
- name: mkdir
shell: mkdir -p /etc/ansible/facts.d
- name: copy vhost.fact
copy: src=/etc/ansible/vhost.fact dest=/etc/ansible/facts.d/vhost.fact
- name: flush
setup:
- name: copy
template: src=set.conf dest=/usr/local/tengine/conf/SET/{{ ansible_local.vhost.general.pro_dir }}.conf
- name: copy
template: src=vhost.conf dest=/usr/local/tengine/conf/conf.d/{{ ansible_local.vhost.general.pro_dir }}.conf
3.手动执行命令
#nginx域名渲染
cd /etc/ansible && python nginx.py
cd /etc/ansible/nginx/
#'host=nginx' 这个是nginx服务器名称
ansible-playbook -i /etc/ansible/hosts vhost.yml --extra-vars 'host=nginx'
ansible -i /etc/ansible/hosts nginx -m shell -a '/usr/local/tengine/sbin/nginx -c /usr/local/tengine/conf/nginx.conf -t'
ansible -i /etc/ansible/hosts nginx -m shell -a '/usr/local/tengine/sbin/nginx -c /usr/local/tengine/conf/nginx.conf -s reload'
达到的效果，利用ansible使两台机器立刻部署完tomcat后，然后加入到nginx中。
土。
