安裝 Nginxmysql
在本教程中,咱們使用 Nginx 做爲 Web 服務器。linux
執行以下命令來安裝 nginxnginx
yum install nginx
安裝完成後,執行以下命令來啓動 Nginxweb
systemctl start nginx.service systemctl enable nginx.service
本實驗以 Python 最新版 , Python 3.6 爲基礎開發。sql
首先,咱們來安裝 Python 3.6django
yum install https://centos7.iuscommunity.org/ius-release.rpm -y yum install python36u -y yum install python36u-pip python36u-devel -y
爲了提高依賴的下載速度,這裏咱們使用清華提供的鏡像源centos
首先,咱們來建立文件夾,用於存儲咱們的配置文件服務器
mkdir ~/.config/pip/
而後在文件內添加以下代碼session
[global] index-url = https://pypi.tuna.tsinghua.edu.cn/simple
首先,咱們來安裝 MySQL ,這裏咱們使用的是 MySQL 的一個發行版 —— MariaDB 。
yum install mariadb mariadb-server -y systemctl start mariadb.service systemctl enable mariadb.service
安裝完成後,執行以下命令來進行 mariadb 的初始化,並根據提示設置 root 的密碼(默認密碼爲空)
mysql_secure_installation
爲了避免影響外界環境的清潔,因此咱們使用虛擬環境來配置 Django 項目
cd /home/ mkdir django cd django python3.6 -m venv venv
建立完成後,執行命令,進入虛擬環境
source venv/bin/activate
而後在虛擬環境中安裝 django 並初始化項目
pip install django django-admin startproject my cd my python manage.py startapp mine
建立完成 App 後,咱們須要修改 my/settings.py
使 Django 能處理來作全部域名中的請求

修改完成後,執行以下命令來啓動 Django 的測試服務器。
python /home/django/my/manage.py runserver 0.0.0.0:80
這時,你能夠訪問 http://<您的 server IP 地址> 查看預覽界面
執行以下命令,退出虛擬環境。
deactivate
接下來,咱們來安裝配置 Uwsgi
yum install gcc -y python3.6 -m pip install uwsgi
執行以下命令,測試使用 uwsgi 來啓動 django
uwsgi --http :80 --chdir /home/django/my --home=/home/django/venv --module my.wsgi
此時,你能夠訪問 https://<您的 Server IP 地址> ,確認是否能夠查看到 django 的測試頁面。
能夠看到後,按下 Ctrl + C ,退出 uwsgi 進程。接下來咱們來配置 Uwsgi。
首先,咱們來建立一個目錄用於存放 Django 的配置文件
mkdir -p /home/django_conf
而後在這個目錄下建立一個文件 [uwsgi.ini].
[uwsgi] socket = /home/django_conf/my.sock chdir = /home/django/my wsgi-file = my/wsgi.py plugins = python virtualenv = /home/django/venv/ processes = 2 threads = 4 chmod-socket = 664 chown-socket = nginx:nginx vacuum = true
這裏的 nginx:nginx 是 nginx 本身的用戶組和用戶名
配置完成 Uwsgi 後,咱們來建立 Nginx 的配置文件(/etc/nginx/conf.d/my.conf)
server { listen 80; server_name <您的 Server IP 地址>; charset utf-8; client_max_body_size 75M; location /media { alias /home/django/my/media; } location /static { alias /home/django/my/static; } location / { uwsgi_pass unix:///home/django_conf/my.sock; include /etc/nginx/uwsgi_params; } }
而後,重啓 Nginx
systemctl restart nginx.service
接下來,咱們來配置 Supervisord ,確保咱們的 django 能夠持久運行
首先,咱們要安裝 pip ,用來安裝 Supervisord。
yum install python-pip -y
安裝完成後,咱們使用 pip 來安裝 supervisord,並輸出配置文件
python -m pip install supervisor echo_supervisord_conf > /etc/supervisord.conf
並在配置文件(/etc/supervisord.conf)底部添加以下代碼
[program:my] command=/usr/bin/uwsgi --ini /home/django_conf/uwsgi.ini directory=/home/django/my startsecs=0 stopwaitsecs=0 autostart=true autorestart=true
添加完成後,執行以下命令來啓動 supervisord
supervisord -c /etc/supervisord.conf
這時,你能夠訪問 http://<您的 Server IP 地址> 查看網站
