FTPでのファイル転送はrootで行う為に以下のサイトを参考

ソフトウェアのインストール

– Go to the server root directory with “cd /”
– yumでInstall required software with
“yum install python-virtualenv nginx gunicorn supervisor python-pip”

– apt-getでInstall required software with “
apt-get install python-virtualenv nginx gunicorn supervisor python-pip

ディレクトリの作成

– Create a new directory for the virtual environment with
“mkdir /opt/envs”

– Create a virtual environment with virtualenv
“virtualenv /opt/envs/virtual”

– Activate the virtual environment
“. /opt/envs/virtual/bin/activate”

– Install Python dependencies
“pip install bokeh”
“pip install flask”
“pip install gunicorn”

– Create a new directory inside the nginx server
“mkdir /var/log/nginx/flask”

– Create a new directory for uploading app files
“mkdir /opt/webapps” “mkdir /opt/webapps/bokehflask”

configuration filesの作成

– Make sure you have your configuration files ready
which are bokeh_serve.conf, flask.conf and default.

FTPアップロード

– Locate your local project directory on the left panel and select your
Python files and the templates directory or any other associated local directory,
but not configuration files

– Locate and select the server directory on the right panel and click Upload
/opt/webapps/bokehflaskにapp.pyとrandom_generator.pyをアップする

– Upload the file named “default” to
/etc/nginx/sites-available
using the same procedure

– Upload files
“bokeh_serve.conf”
and
“flask.conf”
to /etc/supervisor/conf.d using the same procedure

サーバー上での調整

– app.py を編集

以下のコマンドで開く
“nano /opt/webapps/bokehflask/app.py”

– インポート文を追加
“from werkzeug.contrib.fixers import ProxyFix”
to the remote app.py file.

– Modify the index function as follows:

def index():
    url="http://104.236.40.212:5006"
    session=pull_session(url=url,app_path="/random_generator")
    bokeh_script=autoload_server(None,app_path="/random_generator",session_id=session.id, url=url)
    return render_template("index.html", bokeh_script=bokeh_script)

def index():

url="http://104.236.40.212:5006"

session=pull_session(url=url,app_path="/random_generator")

bokeh_script=autoload_server(None,app_path="/random_generator",session_id=session.id, url=url)

return render_template("index.html", bokeh_script=bokeh_script)

– Add “app.wsgi_app = ProxyFix(app.wsgi_app)” to the remote app.py file after the index function.
– Save the file by pressing Control-X, then type y and then hit Enter.

– bokeh_serve.confを編集

以下のコマンドで開く
“nano /etc/supervisor/conf.d/bokeh_serve.conf”
and put your IP for –allow-websocket-origin and your IP and port 5006 for –host

実行

– Start the nginx webserver with
“service nginx restart”

– Start supervisor with
“service supervisor restart”

– Start flask with
“supervisorctl restart flask”

– Start bokeh server with
“supervisorctl restart bokeh_serve”

– Visit your app in the browswer at http://160.16.225.109 (put your own IP)
