python Flask web项目uwsgi + nginx部署
1.安装python
略
2.虚拟环境
2.1安装vertualenv
pip3 install virtualenv
2.2创建虚拟环境
创建保存环境的目录：
mkdir venvs
创建虚拟环境：
[root@root /]# virtualenv /home/xxx/venvs/flask2 --python=python3
查看虚拟环境：
[root@root venvs]# ls
flask2
2.3激活虚拟环境
activiate是激活虚拟环境的命令脚本，在虚拟环境的bin目录下
[root@root bin]# ls
activate activate.fish activate.ps1 deactivate.nu pip3 pip3.7 python3 wheel wheel-3.7
activate.csh activate.nu activate_this.py pip pip-3.7 python python3.7 wheel3 wheel3.7
执行activate激活环境
[root@root bin]# source activate
(flask2) [root@root bin]#
3.环境-uwsgi
3.1安装uwsgi
激活虚拟环境，安装uwsgi
source activate
pip install uwsgi
3.2基于uwsgi运行flask项目
3.2.1命令的方式
uwsgi --http :8080 --wsgi-file app.py --callable app
3.2.2配置文件(推荐)
uwsgi.ini
[uwsgi]
socket = 127.0.0.1:8001
chdir = /home/xxx/data/code/xxx
wsgi-file = app.py
callable = app
processes = 1
virtualenv = /home/xxx/venvs/flask2
启动命令
uwsgi --ini uwsgi.ini
ctrl + c停止
后台启动
uwsgi -d --ini uwsgi.ini
停止
(flask2) [root@root flask]# ps -ef | grep uwsgi
root 7114 6277 0 22:13 pts/1 00:00:00 uwsgi --ini uwsgi.ini
root 7118 6277 0 22:15 pts/1 00:00:00 grep --color=auto uwsgi
(flask2) [root@root flask]# kill -9 7114
4.环境-nginx
4.1安装
4.1.1 yum安装
yum install nginx -y
yum安装失败，未找到nginx包，换使用压缩包编译安装
4.1.2 编译安装
原文：https://www.kuangstudy.com/bbs/1511610238649233410
下载nginx包
下载链接：https://nginx.org/en/download.html
1.nginx的环境依赖下载
编译工具gcc，一般系统都存在
yum install gcc-c++
pcre正则表达式库
yum install -y pcre pcre-devel
zlib解压和压缩库
yum install -y zlib zlib-devel
OpenSSL安全套接字密码库
yum install -y openssl openssl-devel
2.解压
tar -zxvf nginx-1.18.0.tar.gz
3.执行configure
./configure
说明：–prefix参数表示把nginx编译到指定目录
如：--prefix=/www/server/nginx/表示编译到/www/server/nginx/目录下
4.编译
make
5.安装
make install
默认安装目录为/usr/local/nginx
查看nginx安装是否成功
在/usr/local/nginx/sbin目录下执行，无报错则启动成功
./nginx
浏览器输入ip:80查看
如果访问失败，首先检查安全组是否开放80端口，若开放查看防火墙
查看防火墙是否开启
systemctl status firewalld
修改iptables防火墙规则，允许访问80
iptables -I INPUT -p tcp --dport 80 -j ACCEPT
4.2配置

/static/ -> /home/xxx/data/flask/static

4.3启动
在/usr/local/nginx/sbin目录下执行，无报错则启动成功
./nginx -s restart
5.部署
使用uwsgi后台启动项目，在浏览器输入url查看
