1-Django - uwsgi

常见报错

bind(): Cannot assign requested address [core/socket.c line 769]

阿里云 + centos7.5 + python3.9 + django3.2 + uwsgi

首先这可能是偶然的问题，因为我之前的uwsgi.ini的配置是这样的：

[uwsgi]

# 填写crm项目的根目录
chdir=/opt/evcode/demo/

# 填写与项目同名的目录，这是个相对路径，主要就是找到其内的wsgi.py这个文件
module=demo.wsgi

# 虚拟环境的根目录，也就是工作目录
home=/opt/evcode/evenv

# uwsgi的主进程，其他的uwsgi的进程都是这个主进程的子进程，当你kill时，杀掉的也是这个master主进程
master=true

# uwsgi并发时的工作进程的数量，官网的建议是：2 * cup核数 + 1
# 由这几个进程来分摊并发请求
processes=3

# 临时使用http，实际部署时，通过nginx反向代理
#http=0.0.0.0:8566
socket=0.0.0.0:8566

# 当服务器退出时，自动删除unix socket文件和pid文件
vacuum=true

之前运行也好好，直到......某次项目失败......
通过排查发现uwsgi启动失败:

经查百度，有铁子说是阿里云的网络问题，因为我uwsgi.ini配置文件相关的配置是：

socket=0.0.0.0:8566

人家说这个0.0.0.0或者是127.0.0.1需要换成阿里云服务器的内网IP，开始我还不信！后来是在没招了，就抱着试一试的态度，将0.0.0.0换成了我的阿里云服务器的内网ip，然后就好了..........
mmp，希望是个个例！
