一、安裝Apache

# yum install -y httpd httpd-devel

# systemctl start httpd.service    # 啟動(dòng)# systemctl stop httpd.service     # 關(guān)閉# systemctl restart httpd.service   # 重啟# systemctl enable httpd.service    # 開(kāi)機(jī)自啟

防火墻開(kāi)放80端口

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

開(kāi)啟Apache，外網(wǎng)已經(jīng)可以通過(guò)ip訪問(wèn)Apache的默認(rèn)頁(yè)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(xiàng)目

創(chuàng)建flask項(xiàng)目（最簡(jiǎn)單的，一個(gè)項(xiàng)目文件夾、一個(gè)啟動(dòng)文件）

# mkdir /var/www/flask_test    # 項(xiàng)目文件夾# vi /var/www/flask_test/app.py  # 啟動(dòng)文件

啟動(dòng)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(xiàng)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(jìn)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(gè)依賴(lài)，不安裝的話，下面pip會(huì)報(bào)錯(cuò)。。# source py3env/bin/activate        # 進(jìn)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(fù)制下來(lái)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(fù)制上面得到的這行內(nèi)容，添加到配置文件的最后

復(fù)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(xiě)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

配置Apache

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

寫(xiě)入以下內(nèi)容（根據(jù)：https://dormousehole.readthedocs.io/en/latest/deploying/mod_wsgi.html#id1）

<VirtualHost *:80>  ServerName example.com  WSGIScriptAlias / /var/www/flask_test/app.wsgi  <Directory /var/www/flask_test>    Require all granted  </Directory></VirtualHost>

OK了，啟動(dòng)Apache，通過(guò)這臺(tái)服務(wù)器的ip就能訪問(wèn)網(wǎng)頁(yè)了

測(cè)試一些app.py里面寫(xiě)的兩個(gè)路徑
