说明:
参考文档:https://channels.readthedocs.io/en/latest/deploying.html
一、源码修改
1.1、将settings.py
中的DEBUG
的True
改为False
。
1.2、收集静态文件,在settings.py
添加STATIC_ROOT = os.path.join(BASE_DIR, "build/")
,
然后在 manage
的终端中运行collectstatic
可以把静态文件全部复制到build
目录下。
二、运行Daphne
Daphne
是一个用于HTTP、HTTP2和WebSocket协议的ASGI服务器。
# Django2.0.13安装daphne2.2.5版本
pip3 install daphne==2.25
# 可以先cd到项目里面运行下,没报错则继续(静态文件会404,无视它)
cd 项目的路径
cd /root/DeepLearningtaskscopy
# pytho环境路径 -p 监听的端口号 -b 监听的ip asgi的相对位置
/root/py3-env/bin/daphne -p 8002 -b 0.0.0.0 -t 650 DeepLearningtaskscopy.asgi:application
三、安装Nginx
Nginx
是一个高性能的Web服务器/反向代理服务器。
3.1、打开/etc/yum.repos.d/nginx.repo
输入:
[nginx]
name=nginx.repo
baseurl=http://nginx.org/packages/mainline/centos/7/$basearch/
gpgcheck=0
enable=1
3.2、安装:
yum clean all
yum install -y nginx
systemctl enable nginx
systemctl start nginx
四、配置Nginx
4.1、打开/etc/nginx/nginx.conf
修改如下:
主要是把第一行用户nginx
修改为root
,其他修改为优化选项。
include
指定包含其他扩展配置文件,从而简化nginx
主配置文件,实现多个站点功能。
user root;
worker_processes 1;
error_log /var/log/nginx/error.log warn;
pid /var/run/nginx.pid;
events {
worker_connections 1024;
}
http {
include /etc/nginx/mime.types;
default_type application/octet-stream;
log_format main '$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 6500;
types_hash_max_size 2048;
client_max_body_size 10240m;
proxy_connect_timeout 6500;
proxy_send_timeout 6500;
proxy_read_timeout 6500;
send_timeout 6500;
#gzip on;
include /etc/nginx/conf.d/*.conf;
}
4.2、在/etc/nginx/conf.d
目录下新建deeplearning_nginx.conf
配置文件:
location /static/
是匹配static
开头的静态文件直接在alias
目录下查找。
proxy_to_app
是代理Daphne
的配置。
upstream channels-backend {
# http和websocket请求转发配置
server localhost:8001;
}
# configuration of the server
server {
# the port your site will be served on
listen 8008;
# the domain name it will serve for
server_name 192.168.10.180; # substitute your machine's IP address or FQDN
charset utf-8;
location /favicon.ico {
alias /root/DeepLearningtaskscopy/static/favicon.ico;
}
location /static/ {
alias /root/DeepLearningtaskscopy/static/;
}
location / {
try_files $uri @proxy_to_app;
}
location @proxy_to_app {
proxy_pass http://channels-backend;
proxy_http_version 1.1;
proxy_set_header Upgrade $http_upgrade;
proxy_set_header Connection "upgrade";
proxy_redirect off;
proxy_set_header Host $host;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header X-Forwarded-Host $server_name;
proxy_read_timeout 6500;
proxy_send_timeout 6500;
keepalive_timeout 6500;
}
}
4.3、 重新加载 nginx
以应用更改:sudo service nginx reload
五、安装Supervisor
Supervisor
是一套通用的进程管理程序,能监控进程状态,异常退出时能自动重启。
yum install epel-release
yum install -y supervisor
systemctl enable supervisord
systemctl start supervisord
六、配置Supervisor
6.1、Supervisor
的默认配置文件是/etc/supervisord.conf
。
在/etc/supervisord.d
目录下新建deeplearning_daphne.ini
配置文件,管理daphne
进程 :
[program:daphne]
# 执行用户
user = root
# 在该目录下执行下面command命令
directory = /root/DeepLearningtaskscopy
# 执行的命令
command = /root/py3-env/bin/daphne -p 8002 -t 650 DeepLearningtaskscopy.asgi:application
# 日志文件配置,当指定目录不存在时无法正常启动,需要手动创建目录。
loglevel = info
stdout_logfile = /root/deeplearninglogs/daphne.log
stderr_logfile = /root/deeplearninglogs/daphne_error.log
stdout_logfile_maxbytes = 100MB
stdout_logfile_backups = 3
# 给每个进程命名,便于管理
process_name = daphne_worker%(process_num)s
# 启动的进程数
numprocs_start = 1
numprocs = 1
max-requests = 5000
# 设置自启和重启
autostart = true
autorestart = true
redirect_stderr = true
6.2、重新加载 Supervisor
以应用更改:
sudo supervisorctl reread
sudo supervisorctl update
6.3、访问IP:端口,成功!
supervisorctl restart <application name> ;重启指定应用
supervisorctl stop <application name> ;停止指定应用
supervisorctl start <application name> ;启动指定应用
supervisorctl restart all ;重启所有应用
supervisorctl stop all ;停止所有应用
supervisorctl start all ;启动所有应用
supervisorctl status ;查看当前应用状态
