【已解决】CentOS中用supervisor去管理gunicorn的Flask的app
期间，在CentOS中，参考别人帖子，去用pip去安装gunicorn

期间可见：
默认的pip竟然是python3的
也是醉了。
懒得去解决了。
直接用pip2去安装supervisor
因为supervisor不支持python3
<code>[root@naturling-general-01 robotDemo]# ll /etc/su subgid subuid sudo.conf sudoers sudoers.d/ sudo-ldap.conf [root@naturling-general-01 robotDemo]# ll /etc/sup </code>
可见，此处
/etc/下面并没有我们要的supervisor的配置
难道是应该在CentOS中用
yum install supervisor
才会在/etc/下面有配置？
去看看环境变量中是否包含了：echo_supervisord_conf
是有的：
<code>[root@naturling-general-01 robotDemo]# which echo_supervisord_conf -bash: alias: write error: Success /usr/bin/echo_supervisord_conf </code>
not found /etc/supervisor
not supervisord.conf
Configuration File — Supervisor 3.3.4 documentation
默认会去：
“1. $CWD/supervisord.conf
2. $CWD/etc/supervisord.conf
3. /etc/supervisord.conf
4. /etc/supervisor/supervisord.conf (since Supervisor 3.3.0)
5. ../etc/supervisord.conf (Relative to the executable)
6. ../supervisord.conf (Relative to the executable)”
找
python – supervisor.conf default location – Stack Overflow
“You may have installed supervisor via pip and therefore have the unpatched version in
/usr/local/lib/python2.7/dist-packages/supervisor/“
所以去看看：
<code># ll /usr/local/lib/pytho^C </code>
也没有
所以去：
<code>[root@naturling-general-01 robotDemo]# pip2 uninstall supervisor Uninstalling supervisor-3.3.4: Would remove: /usr/bin/echo_supervisord_conf /usr/bin/pidproxy /usr/bin/supervisorctl /usr/bin/supervisord /usr/lib/python2.7/site-packages/supervisor-3.3.4-py2.7-nspkg.pth /usr/lib/python2.7/site-packages/supervisor-3.3.4-py2.7.egg-info /usr/lib/python2.7/site-packages/supervisor/childutils.py /usr/lib/python2.7/site-packages/supervisor/confecho.py /usr/lib/python2.7/site-packages/supervisor/datatypes.py /usr/lib/python2.7/site-packages/supervisor/dispatchers.py /usr/lib/python2.7/site-packages/supervisor/events.py /usr/lib/python2.7/site-packages/supervisor/http.py /usr/lib/python2.7/site-packages/supervisor/http_client.py /usr/lib/python2.7/site-packages/supervisor/loggers.py /usr/lib/python2.7/site-packages/supervisor/medusa/* /usr/lib/python2.7/site-packages/supervisor/options.py /usr/lib/python2.7/site-packages/supervisor/pidproxy.py /usr/lib/python2.7/site-packages/supervisor/poller.py /usr/lib/python2.7/site-packages/supervisor/process.py /usr/lib/python2.7/site-packages/supervisor/rpcinterface.py /usr/lib/python2.7/site-packages/supervisor/scripts/loop_eventgen.py /usr/lib/python2.7/site-packages/supervisor/scripts/loop_listener.py /usr/lib/python2.7/site-packages/supervisor/scripts/sample_commevent.py /usr/lib/python2.7/site-packages/supervisor/scripts/sample_eventlistener.py /usr/lib/python2.7/site-packages/supervisor/scripts/sample_exiting_eventlistener.py /usr/lib/python2.7/site-packages/supervisor/skel/sample.conf /usr/lib/python2.7/site-packages/supervisor/socket_manager.py /usr/lib/python2.7/site-packages/supervisor/states.py /usr/lib/python2.7/site-packages/supervisor/supervisorctl.py /usr/lib/python2.7/site-packages/supervisor/supervisord.py /usr/lib/python2.7/site-packages/supervisor/tests/* /usr/lib/python2.7/site-packages/supervisor/ui/images/button_refresh.gif /usr/lib/python2.7/site-packages/supervisor/ui/images/button_restart.gif /usr/lib/python2.7/site-packages/supervisor/ui/images/button_stop.gif /usr/lib/python2.7/site-packages/supervisor/ui/images/icon.png /usr/lib/python2.7/site-packages/supervisor/ui/images/rule.gif /usr/lib/python2.7/site-packages/supervisor/ui/images/state0.gif /usr/lib/python2.7/site-packages/supervisor/ui/images/state1.gif /usr/lib/python2.7/site-packages/supervisor/ui/images/state2.gif /usr/lib/python2.7/site-packages/supervisor/ui/images/state3.gif /usr/lib/python2.7/site-packages/supervisor/ui/images/supervisor.gif /usr/lib/python2.7/site-packages/supervisor/ui/status.html /usr/lib/python2.7/site-packages/supervisor/ui/stylesheets/supervisor.css /usr/lib/python2.7/site-packages/supervisor/ui/tail.html /usr/lib/python2.7/site-packages/supervisor/version.txt /usr/lib/python2.7/site-packages/supervisor/web.py /usr/lib/python2.7/site-packages/supervisor/xmlrpc.py Proceed (y/n)? y Successfully uninstalled supervisor-3.3.4 </code>
原来是放在了：
/usr/lib/python2.7/site-packages/supervisor/
中了。
不是我们希望的。
所以换成CentOS中的yum去安装：
<code>[root@naturling-general-01 robotDemo]# echo_supervisord_conf ^C [root@naturling-general-01 robotDemo]# which echo_supervisord_conf -bash: alias: write error: Success /usr/bin/echo_supervisord_conf [root@naturling-general-01 robotDemo]# which supervisor -bash: alias: write error: Success /usr/bin/which: no supervisor in (/root/.local/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/root/bin) [root@naturling-general-01 robotDemo]# which supervisord -bash: alias: write error: Success /usr/bin/supervisord [root@naturling-general-01 robotDemo]# which supervisorctl -bash: alias: write error: Success /usr/bin/supervisorctl [root@naturling-general-01 robotDemo]# ll /etc/supervisord.* -rw-r--r-- 1 root root 7953 Jul 29 2017 /etc/supervisord.conf /etc/supervisord.d: total 0 [root@naturling-general-01 robotDemo]# ll /etc/supervisord* -rw-r--r-- 1 root root 7953 Jul 29 2017 /etc/supervisord.conf /etc/supervisord.d: total 0 [root@naturling-general-01 robotDemo]# ll /etc/supervisord. supervisord.conf supervisord.d/ [root@naturling-general-01 robotDemo]# ll /etc/supervisord.d/ total 0 [root@naturling-general-01 robotDemo]# </code>
就安装了，其能找到：
echo_supervisord_conf
/etc/supervisord.conf
/etc/supervisord.d/
了。
【总结】
对于CentOS这类系统，如果用pip去安装的supervisor的话，则默认supervisor会被安装到python所在目录，比如此处的：
<code>pip2 install supervisor </code>
结果supervisor会被安装到，当前python2下：
/usr/lib/python2.7/site-packages/supervisor/
所以，在：
/etc/
下找不到：
supervisord.conf
解决办法是：
用pip去卸载掉：
<code>pip uninstall supervisor pip2 uninstall supervisor </code>
重新用包管理器去安装
CentOS：yum install supervisord
Ubuntu：apt-get install supervisord
即可看到：
/etc/supervisord.conf
/etc/supervisord.d/
