如何解决在运行于EC2的Django实例中更高的内存利用率,这是由于gunicorn.sock的多个运行进程引起的吗?

我的Django实例在ubuntu 16.04.2 LTS之上的EC2上运行。我的api响应非常慢,在调试过程中,我发现几乎所有的内存都被利用了。

以下是屏幕截图供您参考:

ubuntu@ip-xxx-31-22-205:~/Django/user$ free -m
              total        used        free      shared  buff/cache   available
Mem:            990         860          69          10          60          14
Swap:             0           0           0

Top命令对内存利用率并没有多说。这是ps -aux命令的输出

ubuntu@ip-xxx-31-22-205:~/django/user$ ps aux --sort=-%mem | awk 'NR<=10{print $0}'

这是ps -ef命令的输出:

我从这里了解到,在后台运行着多个gunicorn实例。 我创建了一个脚本start_gunicorn.sh来启动gunicorn实例。据我了解,我只能启动实例,但是此脚本无法重启或停止实例。我在这里有两个问题:

  1. gunicorn的多个实例是否导致更高的内存消耗?如果我杀死所有的pid并启动gunicorn脚本,那会有所帮助并且安全吗?

  2. 重新启动和/或停止gunicorn实例的方式是什么?
