Askbot是一个开源问题，答案Web论坛，看起来类似于stackoverflow。
Askbot基于Django框架，大多数零件都以Python编程语言编写，具有一些基于业力的系统，投票和内容审核等良好功能。

Askbot由Ask-Fedoraproject和Ask-OpenStack项目使用，以使用户能够提出问题并让社区其他成员提供贡献。

在我们在Ubuntu 18.04上的AskBot安装中，我们将设置以下准备工作：

数据库服务器 - MySQL/MariaDB/PostgresqluwsgiWeb服务器 - Nginx

第1步：安装askbot依赖项

首先安装所有必需的依赖项，这将是Python软件包和PIP包管理器。

更新和升级系统包：

sudo apt-get update && sudo apt-get upgrade

安装Python依赖项：

sudo apt-get install -y python-dev python-setuptools python-pip libmysqlclient-dev

第2步：安装和配置数据库

对于数据库服务器，我们将使用MariaDB数据库服务器。
请参阅下面的教程，了解如何在Ubuntu 18.04上安装和配置MariaDB数据库服务器：在Ubuntu 18.04和CentOS 7上安装MariaDB 10.3

如果我们有兴趣使用MySQL Server，请检查在CentOS 7/CentOS 6上安装MySQL Server

安装数据库服务器后，为AskBot创建数据库和关联用户：

Hyman@theitroad:~# mysql -u root -p
Enter password: 
Welcome to the MariaDB monitor. Commands end with ; or \g.
Your MariaDB connection id is 21
Server version: 10.3.7-MariaDB-1:10.3.7+maria~bionic mariadb.org binary distribution
Copyright (c) 2000, 2016, Oracle, MariaDB Corporation Ab and others.
Type 'help;' or '\h' for help. Type '\c' to clear the current input statement.
MariaDB [(none)]> CREATE DATABASE askbot_db;
Query OK, 1 row affected (0.000 sec)
MariaDB [(none)]> create user Hyman@theitroad identified by 'Password';
Query OK, 0 rows affected (0.000 sec)
MariaDB [(none)]> grant all privileges on askbot_db.* to Hyman@theitroad;
Query OK, 0 rows affected (0.00 sec)
MariaDB [(none)]> flush privileges;
Query OK, 0 rows affected (0.000 sec)
MariaDB [(none)]> exit
Bye

第3步：安装和配置AskBot

现在我们已经安装了我们需要安装kiskbot的软件包，我们准备好了一个数据库，让我们安装arkbot应用程序。
我们将使用Python Virtualenv为此。

首先创建AskBot用户：

Hyman@theitroad:~# adduser askbot
Adding user `askbot' ...
Adding new group `askbot' (1000) ...
Adding new user `askbot' (1000) with group `askbot' ...
Creating home directory `/home/askbot' ...
Copying files from `/etc/skel' ...
New password: 
Retype new password: 
passwd: password updated successfully
Changing the user information for askbot
Enter the new value, or press ENTER for the default
Full Name []: 
Room Number []: 
Work Phone []: 
Home Phone []: 
Other []: 
Is the information correct? [Y/n] y
Hyman@theitroad:~# id askbot
uid=1000(askbot) gid=1000(askbot) groups=1000(askbot)

将AskBot用户添加到Sudo Group：

$sudo usermod -aG sudo askbot

安装virtualenv：

$sudo pip install virtualenv

100% |████████████████████████████████| 1.9MB 526kB/s 
Installing collected packages: virtualenv
Successfully installed virtualenv-16.0.0

为AskBot内容创建一个目录：

# mkdir /srv/askbot
# chown askbot:askbot /srv/askbot/
# su - askbot
$cd /srv/askbot/

安装VirtualEnv软件包后，为AskBot创建虚拟环境：

$virtualenv venv
New python executable in /srv/askbot/venv/bin/python
Installing setuptools, pip, wheel...done.

来源ENV开始使用它：

$cd venv/
$Hyman@theitroad:/srv/askbot/venv$source bin/activate
(venv) Hyman@theitroad:/srv/askbot/venv$

然后安装AskBot和MySQL Python模块：

$pip install askbot gunicorn mysqlclient mysql-python

Setup AskBot：

(venv) Hyman@theitroad:/srv/askbot/venv$mkdir askbot-app
(venv) Hyman@theitroad:/srv/askbot/venv$cd askbot-app

运行命令 askbot-setup安装问。

(venv) Hyman@theitroad:/srv/askbot/venv/askbot-app$askbot-setup

生成静态文件到Askbot安装目录：

$python manage.py collectstatic

如果我们收到"TypeError：在调用MetaClass Bases时出错"的错误，则会有修复。
我们需要安装六个1.10.0版本。
卸载最新版本并安装v1.10.0

(venv) Hyman@theitroad:/srv/askbot/askbot-app$pip uninstall six 
(venv) Hyman@theitroad:/srv/askbot/askbot-app$pip install six==1.10.0

完成后，将静态文件生成arkbot安装目录：

$python manage.py collectstatic

输入"是"，然后按Enter键继续完成文件的生成。

然后运行 makemigrations和 migrate命令

(venv) Hyman@theitroad:/srv/askbot/askbot-app$python manage.py makemigrations
WARNING!!! You are using a 'locmem' (local memory) caching backend,
which is OK for a low volume site running on a single-process server.
For a multi-process configuration it is neccessary to have a production
cache system, such as redis or memcached.
With local memory caching and multi-process setup you might intermittently
see outdated content on your site.
System check identified some issues:

使用选项生成MySQL数据库 migrate。

(venv) Hyman@theitroad:/srv/askbot/askbot-app$python manage.py migrate

我们也可以使用：

$python manage.py syncdb
...
Synchronizing apps without migrations:
Creating tables...

Installing custom SQL...
Running migrations:
No migrations to apply.
You have installed Django's auth system, and don't have any superusers defined.
Would you like to create one now? (yes/no): yes
Username (leave blank to use 'askbot'): askbot
Email address: Hyman@theitroad
Password: 
Password (again): 
Superuser created successfully.

当脚本询问我们如果要创建超级用户时，请在答案中应答，如果要创建一个。
默认情况下，AskBot为自动创建的第一个用户设置管理状态(超级用户)，但也支持此表单。

使用：测试AskBot安装：

(venv):/srv/askbot/askbot-app$python manage.py runserver 0.0.0.0:8080

访问服务器IP和端口8080.如果一切正常，则应到达下面的仪表板：

步骤5：安装和配置UWSGI&nginx

从APT安装UWSGI：

$sudo apt-get install uwsgi

为AskBot创建UWSGI配置文件：

$sudo vim /etc/uwsgi/apps-enabled/askbot.ini

添加内容：

[uwsgi]

# uwsgi configurations
master = true
processes = 5
uid = www-data
gid=www-data
listen.owner = www-data
listen.group = www-data

# App configurations
chdir=/srv/askbot/askbot-app
wsgi-file=/srv/askbot/askbot-app/django.wsgi
virtualenv=/srv/askbot/venv
socket = /srv/askbot/askbot.sock
chown-socket = www-data:www-data
chmod-socket = 664
vacuum = true
die-on-term = true
logto = /var/log/uwsgi.log
log-master-stream = true

相应地修改文件，然后保存它。

安装nginx：

$sudo apt-get install nginx

重新启动UWSGI服务 www-data作为套接字文件所有者：

$sudo systemctl restart uwsgi

安装CERTBOT for生成Letsencrypt SSL证书：

# wget https://dl.eff.org/certbot-auto -P /usr/local/bin
# chmod a+x /usr/local/bin/certbot-auto

生成Letsencrypt SSL证书：

# systemctl stop nginx
# export DOMAIN='ask.theitroad.com'
# export EMAIL="Hyman@theitroad"
# certbot-auto certonly --standalone -d $DOMAIN \
--preferred-challenges http --agree-tos -n -m $EMAIL \
--keep-until-expiring

如果成功，Certbot将为我们提供成功的信息：

Cleaning up challenges

IMPORTANT NOTES:
 - Congratulations! Your certificate and chain have been saved at:
   /etc/letsencrypt/live/ask.theitroad.com/fullchain.pem
   Your key file has been saved at:
   /etc/letsencrypt/live/ask.theitroad.com/privkey.pem
   Your cert will expire on 2016-09-28. To obtain a new or tweaked
   version of this certificate in the future, simply run certbot-auto
   again. To non-interactively renew *all* of your certificates, run
   "certbot-auto renew"
 - Your account credentials have been saved in your Certbot
   configuration directory at /etc/letsencrypt. You should make a
   secure backup of this folder now. This configuration directory will
   also contain certificates and private keys obtained by Certbot so
   making regular backups of this folder is ideal.
 - If you like Certbot, please consider supporting our work by:

   Donating to ISRG/Let’s Encrypt:   https://letsencrypt.org/donate
   Donating to EFF:                    https://eff.org/donate-le

创建nginx配置文件：

$sudo vim /etc/nginx/conf.d/askbot.conf

确保将变量替换为有效值，然后保存文件。

# Askbot Nginx cofiguration

# cofiguration for https
server {
        listen 443 ssl http2;
        server_name ask.theitroad.com www.ask.theitroad.com;

        ssl on;
        ssl_certificate /etc/letsencrypt/live/ask.theitroad.com/fullchain.pem;
        ssl_certificate_key /etc/letsencrypt/live/ask.theitroad.com/privkey.pem;
        ssl_protocols TLSv1 TLSv1.1 TLSv1.2;

        location /static {
          alias /srv/askbot/askbot-app/static;
        }


        location/{
          include uwsgi_params;
          uwsgi_pass unix:/srv/askbot/askbot.sock;
        }
}

# http to https redirect
server {
        listen 80;
        server_name ask.theitroad.com www.ask.theitroad.com;
        return    301 https://$server_name$request_uri;
}

确认语法是可以的：

$sudo nginx -t
nginx: the configuration file /etc/nginx/nginx.conf syntax is ok
nginx: configuration file /etc/nginx/nginx.conf test is successful

重新启动两者 uwsgi和 nginx改变后的服务。

$sudo systemctl restart uwsgi nginx
