一、安裝Apache

# yum install -y httpd httpd-devel

# systemctl start httpd.service    # 啟動# systemctl stop httpd.service     # 關閉# systemctl restart httpd.service   # 重啟# systemctl enable httpd.service    # 開機自啟

防火墻開放80端口

# firewall-cmd --zone=public --add-port=80/tcp --permanent# firewall-cmd --reload

開啟Apache，外網(wǎng)已經(jīng)可以通過ip訪問Apache的默認頁面了

二、安裝Python36、pip3、virtualenv

# yum install -y epel-release# yum install -y python36# python36 -VPython 3.6.6

# yum install -y python36-setuptools# easy_install-3.6 pip# pip3 -Vpip 18.1 from /usr/local/lib/python3.6/site-packages/pip-18.1-py3.6.egg/pip (python 3.6)

# pip3 install virtualenv

三、創(chuàng)建項目

創(chuàng)建flask項目（最簡單的，一個項目文件夾、一個啟動文件）

# mkdir /var/www/flask_test    # 項目文件夾# vi /var/www/flask_test/app.py  # 啟動文件

啟動文件例子： 

from flask import Flask, request app = Flask(__name__) @app.route('/')def hello_world():  return 'Hello World' @app.route('/hello')def hello():  name = request.args.get('name','')  return 'Hello ' + name + '!' if __name__ == '__main__':  app.run()

在項目文件夾下創(chuàng)建虛擬環(huán)境，安裝flask

# cd /var/www/flask_test# virtualenv py3env      # 創(chuàng)建虛擬環(huán)境# source py3env/bin/activate  # 進入虛擬環(huán)境 (py3env) # pip install flask  # 安裝flask(py3env) # deactivate     # 退出虛擬環(huán)境

四、在虛擬環(huán)境中用pip安裝mod_wsgi

# yum install -y python36-devel.x86_64   # 一個依賴，不安裝的話，下面pip會報錯。。# source py3env/bin/activate        # 進入虛擬環(huán)境(py3env) # pip install mod_wsgi      # 安裝mod_wsgi(py3env) # mod_wsgi-express install-module # 執(zhí)行該命令，把輸出內(nèi)容復制下來LoadModule wsgi_module "/usr/lib64/httpd/modules/mod_wsgi-py36.cpython-36m-x86_64-linux-gnu.so"WSGIPythonHome "/var/www/flask_test/py3env" (py3env) # deactivate           # 退出虛擬環(huán)境

修改Apache的配置

# vi /etc/httpd/conf/httpd.conf

復制上面得到的這行內(nèi)容，添加到配置文件的最后

復制代碼 代碼如下:LoadModule wsgi_module "/usr/lib64/httpd/modules/mod_wsgi-py36.cpython-36m-x86_64-linux-gnu.so"

五、配置mod_wsgi

# vi /var/www/html/flask_test/app.wsgi

寫入以下內(nèi)容（根據(jù)：https://dormousehole.readthedocs.io/en/latest/deploying/mod_wsgi.html）

activate_this = '/var/www/flask_test/py3env/bin/activate_this.py'with open(activate_this) as file_:  exec(file_.read(), dict(__file__=activate_this)) import syssys.path.insert(0, '/var/www/flask_test')from app import app as application
