安装 Django
先安装pip,再通过pip安装Django。
1.安装pip
cd /data; mkdir tmp; cd tmp; wget https://bootstrap.pypa.io/get-pip.py; python ./get-pip.py;
2.使用 PIP，安装 Django
pip install Django==1.11.7
安装 Mysql
1.安装并启动 mariadb
因为 CentOS 7 之后的版本都不在提供 Mysql 安装源，这里我们使用 mariadb 代替 mysql，依次执行下列命令
yum install mariadb mariadb-server -y yum install MySQL-python -y systemctl start mariadb
2.对 mariadb 进行初始化设置
执行下面命令，根据提示操作
设置新密码为 test
默认密码为空，直接回车即可
mysql_secure_installation
3.使用设置的密码登陆 mariadb
登陆 db，这里假设密码被设置为 test
mysql -uroot -ptest
4.创建一个数据库
create database mysite;
5.成功后，输入 exit 命令退出 db
exit
创建 Django 项目
1.创建 mysite 项目
在 /data/ 目录下，创建一个名为 mysite 的 Django 项目
cd /data/ django-admin startproject mysite
2.修改配置文件，与 Mysql 数据库相关联
备注：SECRET_KEY 配置项无需修改
编辑 /data/mysite/mysite/settings.py
示例代码：/data/mysite/mysite/settings.py

3.创建 Django 数据库
cd /data/mysite python manage.py migrate
4.启动 Django
python manage.py runserver
如果没有报错，就说明 Django 已经安装成功了，并且跟 Mysql 的连接正常
5.退出 Django
按 ctrl+c 退出 Django 服务
安装 Nginx
1.通过 yum 安装 Nginx
yum install nginx -y
2.启动 Nginx 服务
systemctl start nginx
访问你的服务器IP，可以看到 nginx 的欢迎界面
http://<您的 server IP 地址>/
安装 uwsgi
使用 yum 命令安装 uwsgi
yum install uwsgi uwsgi-plugin-python -y
让 Nginx，uwsgi，Django 协同工作[精华部分]
1.修改 Nginx 配置文件
编辑 /etc/nginx/nginx.conf
# For more information on configuration, see:
# * Official English Documentation: http://nginx.org/en/docs/
# * Official Russian Documentation: http://nginx.org/ru/docs/
user nginx;
worker_processes auto;
error_log /var/log/nginx/error.log;
pid /run/nginx.pid;
# Load dynamic modules. See /usr/share/nginx/README.dynamic.
include /usr/share/nginx/modules/*.conf;
events {
worker_connections 1024;
}
http {
log_format main '$remote_addr - $remote_user [$time_local] "$request" '
'$status $body_bytes_sent "$http_referer" '
'"$http_user_agent" "$http_x_forwarded_for"';
access_log /var/log/nginx/access.log main;
sendfile on;
tcp_nopush on;
tcp_nodelay on;
keepalive_timeout 65;
types_hash_max_size 2048;
include /etc/nginx/mime.types;
default_type application/octet-stream;
# Load modular configuration files from the /etc/nginx/conf.d directory.
# See http://nginx.org/en/docs/ngx_core_module.html#include
# for more information.
include /etc/nginx/conf.d/*.conf;
server {
listen 80 default_server;
listen [::]:80 default_server;
server_name _;
root /usr/share/nginx/html;
# Load configuration files for the default server block.
include /etc/nginx/default.d/*.conf;
location / {
include uwsgi_params;
uwsgi_pass 127.0.0.1:8000;
}
error_page 404 /404.html;
location = /40x.html {
}
error_page 500 502 503 504 /50x.html;
location = /50x.html {
}
}
# Settings for a TLS enabled server.
#
# server {
# listen 443 ssl http2 default_server;
# listen [::]:443 ssl http2 default_server;
# server_name _;
# root /usr/share/nginx/html;
#
# ssl_certificate "/etc/pki/nginx/server.crt";
# ssl_certificate_key "/etc/pki/nginx/private/server.key";
# ssl_session_cache shared:SSL:1m;
# ssl_session_timeout 10m;
# ssl_ciphers HIGH:!aNULL:!MD5;
# ssl_prefer_server_ciphers on;
#
# # Load configuration files for the default server block.
# include /etc/nginx/default.d/*.conf;
#
# location / {
# }
#
# error_page 404 /404.html;
# location = /40x.html {
# }
#
# error_page 500 502 503 504 /50x.html;
# location = /50x.html {
# }
# }
}
2.重启 Nginx
/usr/sbin/nginx -s reload
3.创建 uwsgi 配置文件
在 /data/mysite 目录下创建 uwsgi.ini，参考下面的内容
示例代码：/data/mysite/uwsgi.ini
[uwsgi] socket = 127.0.0.1:8000 chdir = /data/mysite wsgi-file = mysite/wsgi.py processes = 4 threads = 2 stats = 127.0.0.1:9191 uid = nobody gid = nobody master = true harakiri = 30 daemonize = /data/mysite/uwsgi.log plugins = python
4.启动 uwsgi
uwsgi uwsgi.ini
