1.安裝python

略

2.虛擬環(huán)境

2.1安裝vertualenv

pip3 install virtualenv

2.2創(chuàng)建虛擬環(huán)境

創(chuàng)建保存環(huán)境的目錄：

mkdir venvs

創(chuàng)建虛擬環(huán)境：

[root@root /]# virtualenv /home/xxx/venvs/flask2 --python=python3

查看虛擬環(huán)境：

[root@root venvs]# ls
flask2

2.3激活虛擬環(huán)境

activiate是激活虛擬環(huán)境的命令腳本，在虛擬環(huán)境的bin目錄下

[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

執(zhí)行activate激活環(huán)境

[root@root bin]# source activate
(flask2) [root@root bin]# 

3.環(huán)境-uwsgi

3.1安裝uwsgi

激活虛擬環(huán)境，安裝uwsgi

source activate
pip install uwsgi

3.2基于uwsgi運(yùn)行flask項(xiàng)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(推薦)

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

啟動(dòng)命令

uwsgi --ini uwsgi.ini

ctrl + c停止

后臺(tái)啟動(dòng)

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.環(huán)境-nginx

4.1安裝

4.1.1 yum安裝

yum install nginx -y

yum安裝失敗，未找到nginx包，換使用壓縮包編譯安裝

4.1.2 編譯安裝

原文：https://www.kuangstudy.com/bbs/1511610238649233410

下載nginx包

下載鏈接：https://nginx.org/en/download.html

1.nginx的環(huán)境依賴下載

編譯工具gcc，一般系統(tǒng)都存在

yum install gcc-c++

pcre正則表達(dá)式庫

yum install -y pcre pcre-devel

zlib解壓和壓縮庫

yum install -y zlib zlib-devel

OpenSSL安全套接字密碼庫

yum install -y openssl openssl-devel

2.解壓

tar -zxvf nginx-1.18.0.tar.gz 

3.執(zhí)行configure

./configure

說明：–prefix參數(shù)表示把nginx編譯到指定目錄

如：--prefix=/www/server/nginx/表示編譯到/www/server/nginx/目錄下

4.編譯

make

5.安裝

make install

默認(rèn)安裝目錄為/usr/local/nginx

查看nginx安裝是否成功

在/usr/local/nginx/sbin目錄下執(zhí)行，無報(bào)錯(cuò)則啟動(dòng)成功

./nginx

瀏覽器輸入ip:80查看

如果訪問失敗，首先檢查安全組是否開放80端口，若開放查看防火墻

查看防火墻是否開啟

systemctl  status  firewalld

修改iptables防火墻規(guī)則，允許訪問80

iptables -I INPUT -p tcp --dport 80 -j ACCEPT

4.2配置
