Python flask项目部署
1、安装python3依赖包(以centos7为参考)
yum -y install zlib-devel bzip2-devel openssl-devel ncurses-devel sqlite-devel readline-devel tk-devel
2、下载python3源代码到/usr/local/src
wget https://www.python.org/ftp/python/3.6.8/Python-3.6.8.tgz -O /usr/local/src
3、解压源码包
tar -xzf Python-3.6.8.tgz
4、进入解压后的文件夹
cd Python-3.6.8
5、设置python3编译安装的参数,这里设置安装路径
./configure --prefix=/usr/local/python3.6
6、编译,然后编译安装
make && make install
7、安装完成,设置软连接到/usr/local/bin下
ln -s /usr/local/python3.6/bin/python3.6 /usr/local/bin/python3.6
ln -s /usr/local/python3.6/bin/pip3.6 /usr/local/bin/pip3.6
8、安装和配置 nginx
a.yum install nginx
b.nginx根目录下,配置nginx.conf文件(这里使用的是gunicorn运行脚本)
server {
listen 80;
server_name example.org; # 这是HOST机器的外部域名,用地址也行
location / {
proxy_pass http://127.0.0.1:8080; # 这里是指向 gunicorn host 的服务地址
proxy_set_header Host $host;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
}
}
c.flask项目通过ProxyFix运行
d.最后在nginx根目录下重启nginx:nginx -s reload
9、安装运行python的虚拟环境venv: yum install python-virtualenv
10、创建虚拟环境 virtualen venv
11、进入虚拟环境 source ./bin/activate
12、安装部署flask项目的程序:pip3 install gunicorn
a.运行:cd到flask根目录下 gunicorn -w 4 -b 127.0.0.1:8080 app:app
b.退出:deactivate
13、查看进程:pstree -ap | grep nginx / ps -ef|grep nginx 结束进程:kill -9 ...
14、安装mysql5.7,本地连接服务器mysql:
a、云服务器安全组 - 配置规则 - 添加安全组规则,端口为3306,授权对象0.0.0.0/0
b、授权:GRANT ALL PRIVILEGES ON *.* TO 'root'@'%' IDENTIFIED BY 'root' WITH GRANT OPTION;
c、刷新授权列表:flush privileges;(刷新后还是不行,重启mysql)
