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 --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

在这里插入图片描述

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

在这里插入图片描述

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

普通请求 -> 8001

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