Linebot Django 6

LINE BOT Message 初學者記錄(六) 

Only $2.5 build LINE BOT platform Due to RHC Openshift v2 platform going to closed on 9/30/2017. 只好租個每月 $2.5 美金的 VPS-Vultr. 選它的理由不外乎價位比較便宜且 bot 非商業用途, 硬體需求低.

$2.5 Vultr Plan Spec:

• 20GB SSD
• 1 CPU
• 512MB Memory
• 500GB Bandwidth

Setup:

• OS: CentOS 7
• WebServer: OpenLiteSpeed
• WSGI Server: Gunicorn
• Language: Python3
• Domain: Free source
• SSL: Let’s Encrypt

Step1 - Create VPS and install OS:

Create vultr account then deploy the plan you want. Choose server with CentOS 7x64

You will get server IP and password from overview page

Step2 - Install free web server:

yum update -y
rpm -ivh http://rpms.litespeedtech.com/centos/litespeed-repo-1.1-1.el7.noarch.rpm
yum install openlitespeed -y

Step3 - Install Py3 and Django:

yum -y install https://centos7.iuscommunity.org/ius-release.rpm
yum -y install python36u python36u-devel
yum -y install python36u-pip
pip3.6 install django
django-admin startproject Djangoproject
python3.6 manage.py startapp trips

Step4 - Install Gunicorn:

pip3.6 install gunicorn

Create three files for gunicorn setup:

cat <<EOF>> /etc/systemd/system/gunicorn.socket
Description=gunicorn socket
[Socket]
ListenStream=127.0.0.1:5003
[Install]
WantedBy=sockets.target
EOF

cat <<EOF>> /etc/systemd/system/gunicorn.service
[Unit]
Description=gunicorn daemon
Requires=gunicorn.socket
After=network.target
[Service]
PIDFile=/run/gunicorn/pid
User= root
Group=root
RuntimeDirectory=gunicorn
WorkingDirectory=/root/Djangoproject
ExecStart=/usr/bin/gunicorn --pid /run/gunicorn/pid   \
            --bind 127.0.0.1:5003 trips.wsgi
ExecReload=/bin/kill -s HUP $MAINPID
ExecStop=/bin/kill -s TERM $MAINPID
PrivateTmp=true
[Install]
WantedBy=multi-user.target
EOF

cat <<EOF>> /etc/tmpfiles.d/gunicorn.conf
d /run/gunicorn 0755 root root -
EOF

systemctl start gunicorn.socket

Step5 - Web Server Settings:

WebAdmin > Listensers

1. One Listener for port 80, the other one for 443
2. Both listeners add “Virtual Host Mappings” with $your_domain
3. After Step6 setup, you need to add SSL Key&Cert for port 443

• Private Key: /etc/letsencrypt/live/$your_domain/privkey.pem
• Certificate: /etc/letsencrypt/live/$your_domain/cert.pem
• CA Certificate: /etc/letsencrypt/live/$your_domain/chain.pem

WebAdmin > Server Configuration > External App > Add a “Web Server” Name: gunicorn Address:127.0.0.1:5003 Max Connections:100 Initial Request Timeout: 60 Retry Timeout: 0

WebAdmin console > Configuration > Virtual Hosts > “Virtual Host Name” > Rewrite Rewrite set to Yes **Rewrite</span> **Rewrite Rules:

RewriteCond %{ORG_REQ_URI} !/static
RewriteRule ^/(.*)$ http://gunicorn/$1 [P]

Step6 - Apply for free Domain and SSL:

I choose NCTU.me as my domain hosting, it’s free, immediately effect, easy to use than e.g. HE I choose Let’s encrypt - certbot as my SSL, it’s free and LINE accept it, easy to use and popular. Choose “None of the above” on “CentOS 7” Let’s Encrypt Install:

yum -y install yum-utils
yum-config-manager --enable rhui-REGION-rhel-server-extras rhui-REGION-rhel-server-optional
yum install certbot
certbot certonly
