supervisor使用，需要注意python3 pip

在linux里用pip install supervisor，配置文件都在**/usr/local/python3/bin**里，安装时会有黄色字提醒的：

WARNING: The scripts echo_supervisord_conf, pidproxy, supervisorctl and supervisord are installed in '/usr/local/python3/bin' which is not on PATH.
Consider adding this directory to PATH or, if you prefer to suppress this warning, use --no-warn-script-location.

所以当我们在自己项目里用vim配置好自己写的supervisor.conf 时，执行
supervisord -c supervisor.conf 时，会报错：无法找到supervisord这个包。

解决办法：
cd /usr/local/python3/bin，里面有echo_supervisord_conf, pidproxy, supervisorctl and supervisord 。
我们只要

cp supervisord /usr/bin/

把supervisord复制到/usr/bin/目录下即可

再次执行，亲测可以成功。

/etc/supervisord.conf内容：

 

[supervisord]
logfile = /tmp/supervisord.log
logfile_maxbytes = 50MB
logfile_backups=10
loglevel = info
pidfile = /tmp/supervisord.pid

minfds = 1024
minprocs = 200
umask = 022
identifier = supervisor
directory = /tmp
nocleanup = true
childlogdir = /tmp
strip_ansi = false

[supervisorctl]
serverurl = unix:///tmp/supervisor.sock
prompt = mysupervisor
