@(tigerfive)[学习笔记][flask][python][环境搭建]
1.环境的准备
yum -y install gcc gcc-c++ zlib zlib-devel openssl openssl-devel pcre pcre-devel GeoIP gd libXpm libxslt sqlite-devel nginx
systemctl restart nginx
检测nginx
ps -ef | grep nginx 或 直接浏览器访问
wget https://dev.mysql.com/get/mysql57-community-release-el7-11.noarch.rpm
yum -y install mysql-community-server 安装的是5.7
systemctl start mysqld systemctl enable mysqld
grep password /var/log/mysqld.log
mysqladmin -u root -p‘原密码‘ password ‘新密码‘
mysql -u root -p‘新密码‘
检测mysql
ps -ef | grep mysql 或者
wget https://www.python.org/ftp/python/3.6.0/Python-3.6.0.tgz
2.安装python3.6
tar xvf Python-3.6.0.tgz
cd Python-3.6.0
./configure --prefix=/usr/local/python3.6 && make && make install
3.删除2.7的命令链接,并新建链接
rm -rf /usr/bin/python
ln -s /usr/local/python3.6/bin/python3.6 /usr/bin/python
4.修改环境变量
vim ~/.bash_profile
PATH=$PATH:$HOME/bin:.usr/local/python3.6/bin
5.解决yum失效问题
vim /usr/bin/yum 修改解释器为python2.7
6.测试python是否安装成功
python -V
7.使用pip安装python模块
rm -rf /usr/bin/pip
ln -s /usr/local/python3.6/bin/pip3.6 /usr/bin/pip
8.安装flask
pip install flask
9.创建项目目录
mkdir /root/flask_pro
vim /root/flask_pro/flask_app.py
#vim /root/flask_pro/flask_app.py
from flask import Flask, request
app = Flask(name)br/>@app.route(‘/helloworld/‘)
def helloword():
return ‘hello world‘
if name == ‘main‘ :
app.run(host=‘0.0.0.0‘, port=5005)
测试：python flask_app.py http://+ip/域名:5005/*/
10.安装uwsgi 是python的web容器
pip install uwsig
11.配置uwsgi
vim /root/flask_pro/uwsgi.ini
[uwsgi]
socket=127.0.0.1:5005
chdir=/root/flask_pro/
wsgi-file=flask_app.py
callable=app
processes=2
threads=2
buffer-size=65536
12.nginx配置文件：
#vim /usr/local/nginx/conf/nginx.conf 添加一个虚拟主机，添加到default server前面
server {
listen 80;
server_name xiangmu.buy360.xyz;
location / {
include uwsgi_params;
uwsgi_pass 127.0.0.1:5005;
}
}
注意：添加内容后要把nginx.conf中原先的 server{ listen 80;……} 配置删除或注释掉。
13.uwsgi --ini /root/flask_pro/uwsgi.ini &
实际使用要把上面的命令写到开机启动文件内：rc.local
14.systemctl restart nginx
15.测试：http://192.168.100.10/helloworld/
项目测试
1 拷贝乐居项目 到ls /root/flask_pro/
[root@localhost flask_pro]# ls
app flask_app.py manage.py migrations requirements.txt tests uwsgi.ini venv
而后安装依赖包。
#pip install -r requirements.txt
查看flask项目使用的哪个端口：
#cat manage.py 修改如下内容
if name == ‘main‘:
manager.run(host=‘0.0.0.0‘,port=5000)
2 修改初始化文件，指向乐居
vim uwsgi.ini
[uwsgi]
socket=127.0.0.1:5000
chdir=/root/flask_pro/
wsgi-file=manage.py
callable=app
processes=2
threads=2
buffer-size=65536
3 修改nginx端口转发
server {
listen 80;
server_name xiangmu.buy360.xyz;
location / {
include uwsgi_params;
uwsgi_pass 127.0.0.1:5000;
}
}
4 python 加载uwsgi.ini
#uwsgi -d --ini /root/flask_pro/uwsgi.ini
做开机启动：
#vim /etc/rc.local 追加如下内容
uwsgi -d --ini /root/flask_pro/uwsgi.ini
#chmod +x /etc/rc.d/rc.local
#systemctl enable rc-local
5 重启nginx，并访问。
#systemctl restart nginx
http://xiangmu.buy360.xyz
看到
“RESTFul API 开发测试”
即可。
nginx+uwsgi+python+flask环境搭建
