python3 nginx+uwsgi+Django 部署

安装Nginx(centos7)

1.添加源

sudo rpm -Uvh http://nginx.org/packages/centos/7/noarch/RPMS/nginx-release-centos-7-0.el7.ngx.noarch.rpm

2.安装

sudo yum install -y nginx

3.启动nginx

systemctl start nginx.service
systemctl restart nginx.service
systemctl stop nginx.service

4.浏览器查看效果

在浏览器输入localhost显示Welcon to nginx则安装成功

安装uwsgi

1.安装

pip3 install uwsgi

2.检查

查看/usr/local/bin 或者/usr/bin 中是否有uwsgi命令，因为我的系统中既安装了python2 页安装了python3 ，而我是用pip3安装的uwsgi 所以是安装在了python3的文件夹下的bin中，所以直接输入uwsgi系统找不到该命令，Linux的命令是放在/usr/bin 或/usr/local/bin中，只有在这两个文件中存在才能使用，需要把uwsgi软连接到/usr/bin下才能直接执行命令。

ln -s /usr/local/python3/bin/uwsgi /usr/bin

安装Django

pip3 install Django

部署Django

1.setting中配置项目静态文件路径

STATIC_URL='/static/'

STATICFILES_DIRS=(
os.path.join(BASE_DIR,"static"),
)

STATIC_ROOT='/usr/local/static'
#注意静态文件不要放在root文件夹下，读取的时候会出现权限问题导致网页没有样式，可以自己在根目录下创建一个文件夹存放。

2.收集静态文件

命令：
python3 manage.py collectstatic

3.修改nginx配置

用命令whereis nginx 找到nginx 在/etc/nginx目录下，修改nginx.conf,修改之前最好备份一份。在nginx.conf 的http 中添加server模块。每一个server对应一个服务（app）。

server {
        listen   8500;      #端口
        server_name 0.0.0.0:8500;  #linux中设置为0.0.0.0
        root /root/workspace/projects/python_project/VoiceBotService;#项目路径
        client_max_body_size 100M;
  
        #指定生成的日志路径
        access_log    /root/workspace/projects/python_project/VoiceBotService/nginx_access.log  main;
        error_log     /root/workspace/projects/python_project/VoiceBotService/nginx_error.log  error;

       #项目静态文件路径即setting中的静态路径
        location /static {
            alias /usr/local/VoiceBotService/static/;
        }

       #与uwsgi通信的参数，uwsgi_pass必须和uwsgi.ini文件中法sock一致，必须指定include为uwsgi_params
        location / {
            uwsgi_pass  unix:///usr/local/VoiceBotService/voicebotservice.scok;
            include     /etc/nginx/uwsgi_params;
            proxy_http_version 1.1;
            proxy_redirect off;
            proxy_set_header Upgrade $http_upgrade;
            proxy_set_header Connection "upgrade";
    }

4.创建uwsgi配置文件uwsgi.ini

在项目manage.py 所在目录创建uwsgi.ini文件，添加内容如下：

#uwsgi.ini file
[uwsgi]

# Django-related settings
#http = 0.0.0.0:8500
#socket必须与nginx中一致
socket =  /usr/local/VoiceBotService/voicebotservice.scok
uid = root
pid = root

buffer-size = 65535
#项目路径
chdir = /root/workspace/projects/python_project/VoiceBotService

# Django s wsgi file
#项目wsgi.py路径appname.uwsgi
module = VoiceBotService.wsgi
pipfile=/root/workspace/projects/python_project/VoiceBotService/uwsgi.pid
# process-related settings
# master
master = true
vacuum=true
thunder-lock=true
harakiri=3000
post-buffering=4096

# maximum number of worker processes
processes = 4
# ... with appropriate permissions - may be needed
chmod-socket = 666
# clear environment on exit
vacuum = true
#日志路径
daemonize=/root/workspace/projects/python_project/VoiceBotService/uwsgi.log

5.启动uwsgi

在uwsgi.ini目录下执行命令：
uwsgi --ini uwsgi.ini
执行完命令后会在socket参数指定的目录下生成sockt文件

6.重启Nginx

systemctl restart nginx.restart

每次更新完代码后都要执行5.6步骤。
