uwsgi啟動Django應用

 

uWSGI是一個Web服務器，它實現了WSGI協議、uwsgi、http等協議。

 WSGI / uwsgi / uWSGI 三者區別：

WSGI是一種通信協議,Flask，webpy，Django、CherryPy等等都自帶WSGI，不過性能都不好。

uwsgi同WSGI一樣是一種通信協議。

uWSGI是實現了uwsgi和WSGI兩種協議的Web服務器。

自己配置

uwsgi.ini

# mysite_uwsgi.ini file
[uwsgi]

# Django-related settings
# the base directory (full path)
# 指定運行目錄
chdir = /home/log_collect_statistics
# Django's wsgi file
# 載入wsgi-file
# wsgi-file=log_collect_statistics/uwsgi.ini  #項目目錄下的uwsgi.ini
module= log_collect_statistics.wsgi:application
home = /opt/python
buffer-size = 65536
# process-related settings
# master
# 允許主進程存在
master = true
# maximum number of worker processes
# 開啟的進程數量  # workers 開啟的進程數量，等同於processes（官網的說法是spawn the specified number of  workers / processes）
processes = 4
# the socket (use the full path to be safe
# 地址和端口號，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

# 當服務器退出的時候自動清理環境，刪除unix socket文件和pid文件（try to remove all of the generated file/sockets）
vacuum = true

# 存放進程編號的文件
pidfile=uwsgi.pid

# 日志文件，因為uwsgi可以脫離終端在后台運行，日志看不見。我們以前的runserver是依賴終端的
# 使進程在后台運行，並將日志打到指定的日志文件或者udp服務器（daemonize uWSGI）。實際上最常用的，還是把運行記錄輸出到一個本地文件上
daemonize=logs/uwsgi.log

# 以固定的文件大小（單位KB），切割日志文件。 例如：log-maxsize = 50000000  就是50M一個日志文件。
log-maxsize = 50000000

# 不記錄請求信息的日志。只記錄錯誤以及uWSGI內部消息到日志中。如果不開啟這項，那么你的日志中會大量出現請求記錄
disable-logging = true

1.安裝uWSGI

pip install uwsgi

2.查找安裝的uwsgi位置

find / -name uwsgi

3.建立一個軟連接

ln -r uwsgilujing  /usr/bin/uwsgi

4.在應用目錄，也就是manage.py所在目錄下

 

vi uwsgi.ini[uwsgi]

#使用nginx連接時使用，Django程序所在服務器地址

# socket=ip:80

#直接做web服務器使用，Django程序所在服務器地址

http=ip:80    注意：我用的騰訊雲服務器，ip填寫的是內網地址，不然報錯bind(): Cannot assign requested address [core/socket.c line 769]

#項目目錄

chdir=/root/program/WxFindInfo/mysite/

#項目中wsgi.py文件的目錄，相對於項目目錄

wsgi-file=mysite/wsgi.py

# 進程數

processes=4

# 線程數

threads=2

# uwsgi服務器的角色

master=True

# 存放進程編號的文件

pidfile=uwsgi.pid

# 日志文件，因為uwsgi可以脫離終端在后台運行，日志看不見。我們以前的runserver是依賴終端的

daemonize=uwsgi.log

5.啟動uWSGI服務器

uwsgi --ini uwsgi.ini 

6.停止

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

7.重啟

uwsgi --reload uwsgi.pid
