Linux學習20-nohup掛後臺啓動django

前言

django在linux上運行，通常在xshell遠程鏈接後，是經過python manage.py runserver 0.0.0.0:8000啓動服務。可是這樣有個弊端，窗口關閉服務就中止了。 nohup能夠啓動的時候掛後臺運行

nohup後臺運行

cd到django的manage.py目錄，啓動以前先殺掉進程

[root@yoyo ~]# cd /usr/local/django2/
[root@yoyo django2]# ps -aux | grep python|xargs kill -9
kill: cannot find process "root"
kill: sending signal to 21029 failed: No such process
kill: cannot find process "0.0"
kill: cannot find process "0.0"
kill: sending signal to 112660 failed: No such process
kill: sending signal to 968 failed: No such process
kill: cannot find process "pts/2"
kill: cannot find process "S+"
kill: cannot find process "14:32"
kill: cannot find process "0:00"
kill: cannot find process "grep"
kill: cannot find process "--color=auto"
kill: cannot find process "python"
[root@yoyo django2]#

接着使用nohup啓動進程,能夠指定日誌輸出到djo.out,若是不指定默認是在nohup.out。指定日誌路徑後面加上2>&1 &

[root@yoyo django2]# nohup python manage.py runserver 0.0.0.0:8000 >djo.out 2>&1 &
[1] 21616
[root@yoyo django2]# tail -f djo.out 
nohup: ignoring input
[25/Mar/2019 14:36:31] "GET / HTTP/1.1" 200 24
[25/Mar/2019 14:36:37] "GET / HTTP/1.1" 200 24
[25/Mar/2019 14:36:38] "GET / HTTP/1.1" 200 24
[25/Mar/2019 14:36:39] "GET / HTTP/1.1" 200 24

查看實時日誌能夠用tail -f djo.out

start.sh和stop.sh

接着能夠在manage.py目錄下一個start.sh文件啓動django，再寫個stop.sh停掉django服務。 使用vim start.sh編輯如下2行，編輯完成後Esc退出，輸入:wq保存退出

[root@yoyo django2]# vim start.sh

ps -aux | grep python|xargs kill -9
nohup python manage.py runserver 0.0.0.0:8000 >djo.out 2>&1 &

繼續使用vim start.sh編輯,編輯完成後Esc退出，輸入:wq保存退出

ps -aux | grep python|xargs kill -9

編輯完成以後，受權這2個文件

[root@yoyo django2]# chmod +777 start.sh

[root@yoyo django2]# chmod +777 stop.sh

啓動django

啓動服務執行./start.sh,關閉服務執行./stop.sh

啓動完成後，在瀏覽器輸入地址，而後執行tail -f djo.out能夠看到實時日誌
