Django + Nginx + Uwsgi 配置服務器

Django + Nginx + Uwsgi 配置服務器

---

Django

• 安裝
  密碼：qrzd

tar -zxvf Django-1.6.11.tar.gz
cd Django-1.6.11
python setup.py install

• 新建項目、應用

django-admin.py startproject ~/jiarenyf # 項目名爲jiarenyf
cd ~/jiarenyf
python manage.py startapp ydf # 應用名爲ydf

• 運行應用

 python manage.py runserver 0.0.0.0:4567 # 發佈的ip

Uwsgi

• 安裝

sudo apt-get install python-dev pip # 需要更新python
sudo pip install uwsgi # 需要pip安裝，才能直接支持django

• 支持django

cd ~/jiarenyf
uwsgi --http :4567 --chdir ~/jiarenyf --module ydf.uwsgi
# 但是css、js文件無法加載，需結合nginx

• 配置文件寫法（結合nginx）

<!-- 文件路徑：~/jiarenyf/uwsgi/ydf_socket.xml -->
<uwsgi>
    <socket>/dev/shm/ydf.sock</socket>
    <!-- <socket>127.0.0.1:9000</socket> -->
    <!-- 上述兩種選一種即可，對應的nginx配置要相同 -->
    <chdir>~/jiarenyf</chdir>
    <module>ydf.wsgi</module>
    <processes>4</processes>
    <enable-threads/>
    <chmod-socket>666</chmod-socket>
    <!-- 必須是666…… -->
    <listen>1024</listen>
    <!-- linux默認是128，要修改配置，如下小節 -->
    <!-- <daemonize>~/jiarenyf/uwsgi/ydf_uwsgi.log</daemonize> -->
    <!-- 若使用daemonize參數，則uwsgi會在後臺運行，並將輸出記錄在~/jiarenyf/uwsgi/ydf_uwsgi.log中> -->
</uwsgi>

<!-- 命令行： uwsgi -x ~/jiarenyf/uwsgi/ydf_socket.xml -->

• 修改系統socket最大連接數

vim /etc/sysctl.conf
# 添加：
net.core.somaxconn=1024
# 退出vim
sysctl -p # 使之生效

Nginx

• 安裝

sudo apt-get install nginx

• 收集靜態文件

vim ~/jiarenyf/jiarenyf/settings.py
# 添加：
    STATIC_ROOT=~/jiarenyf/ydf/static
# 退出vim
cd ~/jiarenyf
python manage.py collectstatic

• 配置文件編寫

# 文件路徑：~/jiarenyf/nginx/ydf_nginx.conf
upstream ydf_django{
    server unix:///dev/shm/ydf.sock;
    # server 127.0.0.1:9000;
    # 二選一，要與~/jiarenyf/uwsgi/ydf_socket.xml中socket對應
}

server{
    listen 4567;
    server_name  0.0.0.0;
    charset utf-8;

    client_max_body_size 5M;

    access_log ~/jiarenyf/nginx/access.log;
    error_log ~/jiarenyf/nginx/error.log;

    location /{
        include /etc/nginx/uwsgi_params;
        uwsgi_pass ydf_django;
    }

    location /static{
        alias ~/jiarenyf/ydf/static;
    }

    location /media{
        alias ~/jiarenyf/ydf/media;
    }
}

• 使配置文件生效

sudo ln ~/jiarenyf/nginx/ydf_nginx.conf -s /etc/nginx/site-enabled
sudo service nginx restart
# 或 sudo nginx -s reload
