Ansible一键部署Flask(nginx+Uwsgi)，ansibleflask
Ansible一键部署Flask(nginx+Uwsgi)，ansibleflask
问题：在一台安装有Ansible的主机上如何一键部署Flask到另外一台centos系统的主机?
前提：两台主机网络互通（参考“Ansible入门基础"进行配置）
一，新建目录app和其子目录conf,目录app用于存放Flaks项目文件(.py)，uwsgi配置文件（.ini），playbook运行文件（.yml），子目录conf用于存放nginx配置文件（.conf）
1.
准备目录创建Flask文件
>mkdir app
>cd app
>vim hello.py #创建Flask 项目hello.py
from flaskimportFlask
app = Flask(__name__)
@app.route（‘/’）
def index():
return'<h1>Hello World!!'
if __name__ =="__main__":
app.run(port=8088)
|
2.
>vim test_uwsgi.ini
[uwsgi]
socket =127.0.0.1:8088
chdir = /root/app
processes =4
threads =2
master =true
pythonpath = /root/app #Flask项目所在文件路径
module = hello #因为flask文件名为hello.py
callable = app #因为Flask项目文件中 app = Flask(__name__)
memory-report =true
daemonize =127.0.0.1:8088 #配置让uwsgi在后台运行
|
3.
创建nginx配置文件
>mkdir conf #在app目录下创建conf文件，用于存放nginx.conf配置文件
>cd conf
>vim nginx.conf #nginx 配置文件
include /etc/nginx/conf.d/*.conf;
server {
listen 80default_server;
listen [::]:80default_server;
server_name _;
include /etc/nginx/default.d/*.conf;
location /{
include uwsgi_params:
uwsgi_pass 127.0.0.1:8088 #IP和端口要求与uwsgi配置文件里面的socket值一致
}
}
|
4.
回到app目录下，创建playbook文件
>cd ..
>vim test_build.yml #ansible执行的playbook文件
---
- name: nginx and uwsgi build Flask
hosts:testservers
remote_user: root
tasks:
- name: install nginx and uwsgi and uwsgi-plugin-python
action: yum name={{ item.name }} state=present
with_items:
- { name:'nginx'}
- { name:'uwsgi'}
- { name:'uwsgi-plugin-python'}
- name: create directory
file: state=directory dest=/root/testb/conf
- name: copy file
copy: src={{ item.src }} dest={{ item.dest }}
with_items:
- { src:'/root/app/test_uwsgi.ini',dest:
'/root/testb/test_uwsgi.ini'}
- { src:'/root/app/hello.py', dest:'/root/testb/hello.py'}
- { src:'/root/app/conf/nginx.conf', dest:'/root/testb/conf/nginx.conf'}
- name: build flask
command: uwsgi --http-socket127.0.0.1:8088--plugin
python --ini /root/testb/test_uwsgi.ini
handlers: #handler 启动nginx
- name: start nginx
command: /root/nginx-1.2.7-c
/root/app/conf/nginx.conf #启动nginx指令为：nginx安装目录地址 -c nginx配置文件地址
|
5.
运行playbook文件test_build.yml
>ansible-playbook test_build.yml
|
运行结果截图：
6.
检测是否搭建成功
>curl127.0.0.1:8088
|
返回 Hello World!! 即成功
