折腾：
【未解决】supervisord的普通stdout的log却输出到表示错误的stderr的log中
期间，对于之前的supervisor去管理gunicorn的flask，是好的。
但是加了点log方面的配置：
<code> ;2MB=2*1024*1024=2097152 stdout_logfile=/Users/crifan/dev/dev_root/company/naturling/projects/robotDemo/logs/supervisord_out.log stdout_logfile_maxbytes=2097152 stdout_logfile_backups=10 stderr_logfile=/Users/crifan/dev/dev_root/company/naturling/projects/robotDemo/logs/supervisord_err.log stderr_logfile_maxbytes=2097152 stderr_logfile_backups=10 redirect_stderr=true </code>
结果运行：
<code>➜ robotDemo supervisorctl status all robotDemo STARTING ➜ robotDemo supervisorctl status all robotDemo RUNNING pid 11132, uptime 0:00:00 ➜ robotDemo which python /usr/bin/python ➜ robotDemo supervisorctrl stop all zsh: command not found: supervisorctrl ➜ robotDemo supervisorctl stop all robotDemo: stopped ➜ robotDemo supervisorctl start all robotDemo: started ➜ robotDemo supervisorctl status all robotDemo STARTING ➜ robotDemo supervisorctl status all robotDemo STARTING ➜ robotDemo supervisorctl status all robotDemo STARTING ➜ robotDemo supervisorctl status all robotDemo STARTING ➜ robotDemo supervisorctl status all robotDemo STARTING ➜ robotDemo supervisorctl status all robotDemo STARTING </code>
出错了：
err中空了：
out中：
全是：
<code>supervisor: couldn't setuid to 0: Can't drop privilege as nonroot user supervisor: child process was not spawned supervisor: couldn't setuid to 0: Can't drop privilege as nonroot user supervisor: child process was not spawned </code>
去掉
redirect_stderr=true
试试
结果问题依旧：
另外和之前一样，去调用get接口时出错：
<code>org.apache.http.conn.HttpHostConnectException: Connect to 127.0.0.1:32851 [/127.0.0.1] failed: Connection refused (Connection refused) </code>
难道是没有指定配置文件？
那为何其可以找得到我之前的app的名字呢？
去试试指定配置文件：
<code>➜ robotDemo supervisorctl -c supervisord.conf robotDemo STOPPED Apr 20 06:05 PM supervisor> ^D ➜ robotDemo supervisorctl -c supervisord.conf robotDemo STOPPED Apr 20 06:05 PM supervisor> ^D ➜ robotDemo supervisord -c supervisord.conf Error: Another program is already listening on a port that one of our HTTP servers is configured to use. Shut this program down first before starting supervisord.

Shut this program down first before starting supervisord. For help, use /Users/crifan/Library/Python/2.7/bin/supervisord -h </code>
supervisor: couldn’t setuid to 0: Can’t drop privilege as nonroot user
CRIT Can’t drop privilege as nonroot user · Issue #695 · Supervisor/supervisor
难道是之前给
supervisord.conf
加了配置：
<code>user=root </code>
导致的？
“*、不通过root启动
修改用户
[supervisord]
user=user1 ; (default is current user, required if root)
[supervisorctl]
username=user1 ; should be same as http_username if set”

去用sudo用户去停止掉supervisor
<code>➜ robotDemo sudo supervisorctl stop all Password: robotDemo: stopped ➜ robotDemo sudo supervisorctl status all robotDemo STOPPED Apr 23 09:06 AM </code>
然后把之前自己加到：
supervisord.conf
中的user去掉：
然后再去（默认用当前用户去）启动：
<code>➜ robotDemo supervisorctl status all robotDemo STARTING ➜ robotDemo supervisorctl status all robotDemo RUNNING pid 1041, uptime 0:00:00 ➜ robotDemo supervisorctl status all robotDemo STARTING ➜ robotDemo supervisorctl status all robotDemo RUNNING pid 1059, uptime 0:00:00 ➜ robotDemo supervisorctl status all robotDemo RUNNING pid 1069, uptime 0:00:00 </code>
结果问题依旧。
再去停止掉，继续试试supervisorctl是否正常。
结果又提示：
<code>➜ robotDemo supervisorctl status all unix:///tmp/supervisor.sock no such file ➜ robotDemo supervisorctl start all unix:///tmp/supervisor.sock no such file </code>
搜：
supervisorctl unix:///tmp/supervisor.sock no such file
supervisorctl报错unix:///tmp/supervisor.sock no s… – 简书
去看看，是否存在此文件
<code>➜ robotDemo ll /tmp/supervisord.log -rw-r--r-- 1 crifan wheel 19M 4 23 09:18 /tmp/supervisord.log ➜ robotDemo ll /tmp/supervisor* -rw-r--r-- 1 crifan wheel 19M 4 23 09:18 /tmp/supervisord.log </code>
只有一个log
没有这个sock文件
“unix:///tmp/supervisor.sock no such file” 错误处理 – CashQian Blog
此处不用去改，先去update，表示更新配置文件，试试如何
<code>➜ robotDemo supervisorctl update </code>
error: <class ‘socket.error’>, [Errno 2] No such file or directory: file: /System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/socket.py line: 228
结果找不到socket
还是去换个路径吧
但是感觉随便换还是不太好。

嗯，去touch一下
<code>➜ robotDemo touch /tmp/supervisor.sock ➜ robotDemo ll /tmp/supervisor* -rw-r--r-- 1 crifan wheel 0B 4 23 09:28 /tmp/supervisor.sock -rw-r--r-- 1 crifan wheel 19M 4 23 09:18 /tmp/supervisord.log ➜ robotDemo rm /tmp/supervisord.log ➜ robotDemo ll /tmp/supervisor* -rw-r--r-- 1 crifan wheel 0B 4 23 09:28 /tmp/supervisor.sock </code>
然后再去运行看看
结果又提示，不是socket文件：
<code>➜ robotDemo supervisorctl status all error: <class 'socket.error'>, [Errno 38] Socket operation on non-socket: file: /System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/socket.py line: 228 </code>
刚发现此处一个小问题：
配置文件中，没看到之前就有：
[supervisord]
后面自己加了：
[supervisord]
所以去掉最后的，使用前面的。
另外参考：
http://www.cashqian.net/blog/001472975510127673ea63db9234c4e8293cf43cefcafde000
去改为：
把所有的
/tmp/
都改为
/var/run/

然后更新一下配置文件，结果还是报错：
<code>➜ robotDemo supervisorctl update error: <class 'socket.error'>, [Errno 2] No such file or directory: file: /System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/socket.py line: 228 </code>

解决 supevisor 提示 socket error 错误
然后去新建，给权限，弄了一半，算了放弃吧：

再去搜：

Stopping supervisord: Shut down – Stack Overflow
然后发现：
此处虽然显示出：
<code>➜ robotDemo supervisord -c supervisord.conf Unlinking stale socket /var/run/supervisor.sock </code>
但是实际上是已经正常运行了
所以再去运行就提示：
<code>➜ robotDemo supervisord -c supervisord.conf Error: Another program is already listening on a port that one of our HTTP servers is configured to use. Shut this program down first before starting supervisord. For help, use /Users/crifan/Library/Python/2.7/bin/supervisord -h </code>
以及去测试自己的Flask接口，也是OK的了，也可以看到对应的log：
【总结】
此处，最终是去修改配置文件：
supervisord.conf
把：
/tmp/
都改为
/var/run/
变成：
<code>[unix_http_server] ;file=/tmp/supervisor.sock ; the path to the socket file file=/var/run/supervisor.sock ; the path to the socket file chmod=0766 ; socket file mode (default 0700) </code>
[supervisord]
;logfile=/tmp/supervisord.log ; main log file; default $CWD/supervisord.log
logfile=/var/run/supervisord.log ; main log file; default $CWD/supervisord.log
logfile_maxbytes=50MB ; max main logfile bytes b4 rotation; default 50MB
logfile_backups=10 ; # of main logfile backups; 0 means none, default 10
loglevel=info ; log level; default info; others: debug,warn,trace
;pidfile=/tmp/supervisord.pid ; supervisord pidfile; default supervisord.pid
pidfile=/var/run/supervisord.pid ; supervisord pidfile; default supervisord.pid
[supervisorctl]
;serverurl=unix:///tmp/supervisor.sock ; use a unix:// URL for a unix socket
serverurl=unix:///var/run/supervisor.sock ; use a unix:// URL for a unix socket
然后再去对应的文件夹中创建对应文件，且更改为当前用的权限：
<code>➜ robotDemo sudo touch /var/run/supervisor.sock ➜ robotDemo sudo touch /var/run/supervisord.log ➜ robotDemo sudo touch /var/run/supervisord.pid ➜ robotDemo sudo chown crifan:staff /var/run/supervisor* ➜ robotDemo ll /var/run/supervisor* -rw-r--r-- 1 crifan staff 0B 4 23 09:44 /var/run/supervisor.sock -rw-r--r-- 1 crifan staff 0B 4 23 09:47 /var/run/supervisord.log -rw-r--r-- 1 crifan staff 0B 4 23 09:47 /var/run/supervisord.pid </code>
其中crifan:staff是参考：
<code>➜ robotDemo ll total 80 -rw-r--r-- 1 crifan staff 212B 4 20 10:15 Pipfile -rw-r--r-- 1 crifan staff 7.8K 4 20 10:16 Pipfile.lock drwxr-xr-x 3 crifan staff 96B 4 20 16:55 __pycache__ -rw-r--r-- 1 crifan staff 8.3K 4 20 13:46 app.py -rw-r--r-- 1 crifan staff 1.6K 4 20 13:45 gunicorn_config.py drwxr-xr-x 7 crifan staff 224B 4 23 09:17 logs -rw-r--r-- 1 crifan staff 9.8K 4 23 09:36 supervisord.conf </code>
看到的。
以及再去给此处的/var/run允许当前用户访问的权限：
<code>➜ robotDemo sudo chmod 777 /var/run </code>
最终才能正常运行supervisord：
<code>➜ robotDemo supervisord -c supervisord.conf Unlinking stale socket /var/run/supervisor.sock </code>
注意：
此处输出：
Unlinking stale socket /var/run/supervisor.sock
不是错误 -》实践上supervisord已经正常运行了。
-〉后来发现是：
其实log已经都输出到：
supervisord.conf
中配置的：
<code>[supervisord] logfile=/Users/crifan/dev/dev_root/company/naturling/projects/robotDemo/logs/supervisord.log </code>
中了：
