Centos django+uwsgi+nginx部署
安装Python
CentOS 7 Linux发行版默认包含Python 2。但是，Python 2将于1月1日停产。尽管一些遗留应用程序可能由于各种原因需要访问Python 2，但是启动Python 3中的新项目至关重要。
通过软件管理包Yum
更新环境
$ yum update -y
-y：安装包的时候会询问y/n,这个参数是所有询问默认y，下边不再提醒，在终端输入以上命令时，直接下载安装，不再要求确认。
在7.7之前的CentOS 7版本中，CentOS基本存储库没有提供Python 3软件包。从CentOS 7.7开始，Python 3可在基本软件包存储库中使用！
安装Python3
$ yum install -y python3
源码安装
环境依赖
$ yum install gcc openssl-devel bzip2-devel libffi-devel -y
下载Python
# 下载$ wget /ftp/python/3.8.3/Python-3.8.3.tgz# 解压$ tar -xzf Python-3.8.3.tgz
安装Python3
进入目录
$ cd Python-3.8.3/
编译
$ ./configure --enable-optimizations
安装
$ make && make install
uwsgi
安装uwsgi
由于uWSGI由EPEL提供，因此无需使用进行安装pip。
$ yum -y install uwsgi uwsgi-plugin-python3
配置uwsgi
在django项目manage.py同级目录下，创建uwsgi.ini文件。
[uwsgi]chdir=/home/wj/Project/data_analysismodule=data_analysis.wsgi:applicationsocket=:8000processes=5threads=2master=Truepidfile=uwsgi.pidvacuum=Truemax-requests=5000daemonize=uwsgi.logenv DJANGO_SETTINGS_MODULE=data_analysis.settingshome=/home/wj/Envs/django
注意：如果后期运行时出现以下这种错误，只需在uwsgi.ini文件里添加plugins = python36（python36是Python版本）
-- unavailable modifier requested: 0 --
运行uwsgi
$ uwsgi --ini uwsgi.ini
会生成指定自己指定名称的.log文件和.pid文件
停止uwsgi
$ uwsgi --stop uwsgi.pid
nginx
安装
$ yum install -y nginx
配置nginx
查看nginx配置文件位置
$ nginx -tnginx: the configuration file /etc/nginx/nginx.conf syntax is oknginx: configuration file /etc/nginx/nginx.conf test is successful
查看配置文件/etc/nginx/nginx.conf
$ cat /etc/nginx/nginx.conf# For more information on configuration, see:# * Official English Documentation: /en/docs/# * Official Russian Documentation: /ru/docs/user nginx;worker_processes auto;error_log /var/log/nginx/error.log;pid /var/run/nginx.pid;# Load dynamic modules.

我们只需关注include /etc/nginx/conf.d/*.conf;
进入/etc/nginx/conf.d/，在此目录下创建以.conf结尾的文件。
创建配置文件
$ vim django.conf# mysite_nginx.confupstream django {server 127.0.0.1:8001; # 服务器的套接字}server {# 监听的端口号listen8000;# 编码charsetutf-8;# Finally, send all non-media requests to the Django server.location / {uwsgi_pass django;includeuwsgi_params; # 可下载，也可自己创建文件。}}
uwsgi_params：/nginx/nginx/blob/master/conf/uwsgi_params
uwsgi_param QUERY_STRING $query_string;uwsgi_param REQUEST_METHOD$request_method;uwsgi_param CONTENT_TYPE $content_type;uwsgi_param CONTENT_LENGTH$content_length;uwsgi_param REQUEST_URI $request_uri;uwsgi_param PATH_INFO$document_uri;uwsgi_param DOCUMENT_ROOT$document_root;uwsgi_param SERVER_PROTOCOL $server_protocol;uwsgi_param REQUEST_SCHEME$scheme;uwsgi_param HTTPS $https if_not_empty;uwsgi_param REMOTE_ADDR $remote_addr;uwsgi_param REMOTE_PORT $remote_port;uwsgi_param SERVER_PORT $server_port;uwsgi_param SERVER_NAME $server_name;
检查nginx配置
$ nginx -tnginx: the configuration file /etc/nginx/nginx.conf syntax is oknginx: configuration file /etc/nginx/nginx.conf test is successful
启动nginx
$ service nginx restart
