uwsgi启动Django应用

uWSGI是一个Web服务器，它实现了WSGI协议、uwsgi、http等协议。

WSGI / uwsgi / uWSGI 三者区别：

WSGI是一种通信协议,Flask，webpy，Django、CherryPy等等都自带WSGI，不过性能都不好。

uwsgi同WSGI一样是一种通信协议。

uWSGI是实现了uwsgi和WSGI两种协议的Web服务器。

自己配置

uwsgi.ini

# mysite_uwsgi.ini file

[uwsgi]

# Django-related settings

# the base directory (full path)

# 指定运行目录

chdir = /home/log_collect_statistics

# Django's wsgi file

# 载入wsgi-file

# wsgi-file=log_collect_statistics/uwsgi.ini  #项目目录下的uwsgi.ini

module= log_collect_statistics.wsgi:application

home = /opt/python

buffer-size = 65536

# process-related settings

# master

# 允许主进程存在

master = true

# maximum number of worker processes

# 开启的进程数量  # workers 开启的进程数量，等同于processes（官网的说法是spawn the specified number of  workers / processes）

processes = 4

# the socket (use the full path to be safe

# 地址和端口号，例如：socket = 127.0.0.1:50000

socket = :8080

#http= 192.168.8.192:8081

#http-socket = 192.168.8.192:8081

#http://60.205.211.11 172.17.36.8

# ... with appropriate permissions - may be needed

# chmod-socket = 664

# clear environment on exit

#http-socket = 172.17.36.8:8081

enable-threads = true

# 当服务器退出的时候自动清理环境，删除unix socket文件和pid文件（try to remove all of the generated file/sockets）

vacuum = true

# 存放进程编号的文件

pidfile=uwsgi.pid

# 日志文件，因为uwsgi可以脱离终端在后台运行，日志看不见。我们以前的runserver是依赖终端的

# 使进程在后台运行，并将日志打到指定的日志文件或者udp服务器（daemonize uWSGI）。实际上最常用的，还是把运行记录输出到一个本地文件上

daemonize=logs/uwsgi.log

# 以固定的文件大小（单位KB），切割日志文件。 例如：log-maxsize = 50000000  就是50M一个日志文件。

log-maxsize = 50000000

# 不记录请求信息的日志。只记录错误以及uWSGI内部消息到日志中。如果不开启这项，那么你的日志中会大量出现请求记录

disable-logging = true

1.安装uWSGI

pip install uwsgi

2.查找安装的uwsgi位置

find / -name uwsgi

3.建立一个软连接

ln -r uwsgilujing /usr/bin/uwsgi

4.在应用目录，也就是manage.py所在目录下

vi uwsgi.ini[uwsgi]

#使用nginx连接时使用，Django程序所在服务器地址

# socket=ip:80

#直接做web服务器使用，Django程序所在服务器地址

http=ip:80 注意：我用的腾讯云服务器，ip填写的是内网地址，不然报错bind(): Cannot assign requested address [core/socket.c line 769]

# 存放进程编号的文件

pidfile=uwsgi.pid

# 日志文件，因为uwsgi可以脱离终端在后台运行，日志看不见。我们以前的runserver是依赖终端的

daemonize=uwsgi.log

5.启动uWSGI服务器

uwsgi --ini uwsgi.ini

6.停止

uwsgi --stop uwsgi.pid/kill -9 pid

7.重启

uwsgi --reload uwsgi.pid
