折腾：
【已解决】把Python3的Flask部署到远程CentOS7服务器
期间，之前Mac本地已经折腾完毕了，现在已在CentOS中弄好了gunicorn。
现在接着去弄supervisor。
不过之前mac本地折腾的supervisor，不是全局安装的。
现在CentOS服务器中要全局安装，尤其是配置要全局。
因为后期可能会用supervisor去管理，不止当前这一个app。
所以supervisor的log，倒是考虑放在全局，而不是当前app下面。
然后对于supervisor的其他如sock和pid等文件，最好放的，重启服务器不会删掉的非tmp的目录，比如之前的/var/run，但是为了更加规范不乱，可以考虑放到：
/var/run/supervisor/
中。
现在继续重新研究：

【已解决】CentOS中用python2的pip去安装supervisor后找不到/etc/supervisor中的默认配置文件supervisord.conf
看了看默认的配置：

[include]
files = supervisord.d/*.ini
[root@naturling-general-01 robotDemo]#
</code>好像有点奇怪：
<code>[include] files = supervisord.d/*.ini </code>
为何不是*.conf？
默认sock文件：file=/var/run/supervisor/supervisor.sock
默认log文件：logfile=/var/log/supervisor/supervisord.log
默认pid文件：pidfile=/var/run/supervisord.pid
默认：serverurl=unix:///var/run/supervisor/supervisor.sock
对于此处supervisor的运行机制，加载配置的机制，感觉是：
如果别人在项目目录下创建的配置文件中只是简单的：
<code>[program:myapp] directory= /home/flask command= gunicorn -w4 -b0.0.0.0:5000 run:app </code>
而没有配置sock，log，pid等文件，则：
估计是supervisor先去加载系统默认的：
/etc/supervisor.conf
然后再去加载单个app的配置的。
然后对于某个（Flask的app）项目 的supervisor配置文件的存放的位置，感觉是：
可以放到项目目录下
也可以放到（此处的）/etc/supervisord.d/中-》让supervisor自动识别
鉴于官网：
Configuration File — Supervisor 3.3.4 documentation
提到的搜索路径，没包含此处CentOS用yum安装后的supervisor的conf的路径：
/etc/supervisord.d
以及默认配置：
/etc/supervisord.conf
中最后竟然include是ini而不是conf，所以去参考：
python – supervisor.conf default location – Stack Overflow
修改现有的：
/etc/supervisord.conf
的最后部分为：
<code>(robotDemo-dwdcgdaG) [root@naturling-general-01 robotDemo]# cat /etc/supervisord.conf [include] ;files = supervisord.d/*.ini files = /etc/supervisord.d/*.conf </code>
这样就可以让supervisor自动包含：
/etc/supervisord.d/
下面所有的conf配置了。
不过此处还是为了项目逻辑性更清晰，把自己的supervisor的conf放到自己项目根目录下吧
继续参考：
supervisor 和gunicorn部署django项目-Linux运维日志
优化配置：
supervisord_robotDemo.conf
<code>[program:robotDemo] command=/root/.local/share/virtualenvs/robotDemo-dwdcgdaG/bin/gunicorn -c gunicorn_config.py app:app directory=/root/naturling_20180101/web/server/robotDemo startsecs=0 stopwaitsecs=0 autostart=true autorestart=true killasgroup=true stopasgroup=true stdout_logfile=/root/naturling_20180101/web/server/robotDemo/logs/%(program_name)s-stdout.log stdout_logfile_maxbytes=2MB stdout_logfile_backups=10 stderr_logfile=/root/naturling_20180101/web/server/robotDemo/logs/%(program_name)s-stderr.log stderr_logfile_maxbytes=2MB stderr_logfile_backups=10 </code>
结果运行却出错：
<code>[root@naturling-general-01 robotDemo]# supervisord -c supervisord_robotDemo.conf Error: .ini file does not include supervisord section For help, use /usr/bin/supervisord -h </code>
很明显，此处是由于没有包含：
[supervisord]
但是别人为何这么写。
然后发现别人都是放到/etc下面的
所以还是去放到/etc下面去看看吧
<code>[root@naturling-general-01 robotDemo]# mv supervisord_robotDemo.conf /etc/supervisord.d/ [root@naturling-general-01 robotDemo]# ll /etc/supervisord.d total 4 -rw-r--r-- 1 root root 568 Apr 24 13:38 supervisord_robotDemo.conf </code>
然后再去运行，不加参数：
<code>[root@naturling-general-01 robotDemo]# supervisord /usr/lib/python2.7/site-packages/supervisor/options.py:296: UserWarning: Supervisord is running as root and it is searching for its configuration file in default locations (including its current working directory); you probably want to specify a "-c" argument specifying an absolute path to a configuration file for improved security. 'Supervisord is running as root and it is searching ' </code>
好像还是没有运行？
貌似已经运行了：
<code>[root@naturling-general-01 robotDemo]# ps -ef | grep supervisor root 32338 1 0 13:43 ? 00:00:00 /usr/bin/python /usr/bin/supervisord root 32438 31807 0 13:44 pts/0 00:00:00 grep --color=auto supervisor </code>
然后再去运行supervisorctl看看
<code>[root@naturling-general-01 robotDemo]# supervisorctl status all robotDemo RUNNING pid 32340, uptime 0:01:17 </code>
和log：
<code>[root@naturling-general-01 robotDemo]# cat /var/log/supervisor/supervisord.log 2018-04-24 13:43:37,742 CRIT Supervisor running as root (no user in config file) 2018-04-24 13:43:37,742 WARN Included extra file "/etc/supervisord.d/supervisord_robotDemo.conf" during parsing 2018-04-24 13:43:37,765 INFO RPC interface 'supervisor' initialized 2018-04-24 13:43:37,765 CRIT Server 'unix_http_server' running without any HTTP authentication checking 2018-04-24 13:43:37,767 INFO daemonizing the supervisord process 2018-04-24 13:43:37,768 INFO supervisord started with pid 32338 2018-04-24 13:43:38,771 INFO spawned: 'robotDemo' with pid 32340 2018-04-24 13:43:39,306 INFO success: robotDemo entered RUNNING state, process has stayed up for > than 0 seconds (startsecs) </code>
然后对应的此处的其他logs，也是对的：

</code>然后再去试试其他命令：
<code>[root@naturling-general-01 robotDemo]# supervisorctl stop all robotDemo: stopped [root@naturling-general-01 robotDemo]# supervisorctl status all robotDemo STOPPED Apr 24 01:49 PM [root@naturling-general-01 robotDemo]# supervisorctl restart all robotDemo: started [root@naturling-general-01 robotDemo]# supervisorctl status all robotDemo RUNNING pid 32741, uptime 0:00:03 [root@naturling-general-01 robotDemo]# supervisorctl status all robotDemo RUNNING pid 32741, uptime 0:00:04 </code>
貌似也都是正常的。
接着，再去考虑加到启动中
centos supervisor bootable
centos supervisor add to autostart
install and configure supervisord on centos 7.
<code>systemctl -a | grep supervisor </code>
好像并没有找到supervisor

很明显，此处貌似是有：
supervisord.service
的，但是systemctl失败了。
但是失败的错误，通过
<code>systemctl status supervisord.service journalctl -xe </code>
好像看不太懂。
去看看service文件：
<code>[root@naturling-general-01 robotDemo]# ll /usr/lib/systemd/system/supervisord.service -rw-r--r-- 1 root root 221 Jul 29 2017 /usr/lib/systemd/system/supervisord.service [root@naturling-general-01 robotDemo]# cat /usr/lib/systemd/system/supervisord.service [Unit] Description=Process Monitoring and Control Daemon After=rc-local.service nss-user-lookup.target [Service] Type=forking ExecStart=/usr/bin/supervisord -c /etc/supervisord.conf [Install] WantedBy=multi-user.target [root@naturling-general-01 robotDemo]# </code>
在CentOS上安装并配置Supervisor – 为程序员服务
Job for supervisord.service failed because the control process exited with error code
systemctl start supervisord failed
在centos7上使用systemd启动supervisor – 简书
去对比看看此处的配置，好像是少了很多，比如：
ExecStop=/usr/bin/supervisorctl $OPTIONS shutdown
ExecReload=/usr/bin/supervisorctl $OPTIONS reload
但是看到ExecStart的/usr/bin/supervisord
那么就去手动试试：
<code>[root@naturling-general-01 robotDemo]# /usr/bin/supervisord -c /etc/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 /usr/bin/supervisord -h </code>
很明显，是有端口被占用了。。。
所以去看看是哪个程序占用了
<code>[root@naturling-general-01 robotDemo]# ps -ef | grep supervisor root 1149 31807 0 14:04 pts/0 00:00:00 grep --color=auto supervisor root 32338 1 0 13:43 ? 00:00:00 /usr/bin/python /usr/bin/supervisord </code>
很明显是之前的还没有kill掉，去kill掉：
<code>[root@naturling-general-01 robotDemo]# ps -ef | grep supervisor root 1237 1199 0 14:05 pts/0 00:00:00 grep --color=auto supervisor root 32338 1 0 13:43 ? 00:00:00 /usr/bin/python /usr/bin/supervisord [root@naturling-general-01 robotDemo]# kill -9 1237 -bash: kill: (1237) - No such process [root@naturling-general-01 robotDemo]# kill -9 32338 [root@naturling-general-01 robotDemo]# ps -ef | grep supervisor root 1264 1199 0 14:05 pts/0 00:00:00 grep --color=auto supervisor </code>
然后再去systemctl试试

貌似就可以了。
即，kill之前正在运行的supervisord后，再去：
systemctl start supervisord
systemctl restart supervisord
都可以正常启动的。
然后通过：
systemctl enable supervisord
实现加到开机启动
其他命令：
查看状态：systemctl status supervisord
停止：systemctl stop supervisord
然后直接去reboot服务器，看看机器启动后，是否正常启动supervisord

说明是正常启动的。
【总结】
此处去：
CentOS：yum install supervisord
Ubuntu：apt-get install supervisord
安装supervisord，则可以在/etc中看到默认的配置和对应文件夹：
/etc/supervisord.conf
/etc/supervisord.d/
（注：如果用pip去安装，则会导致supervisord被安装到python的site-packages目录下了，比如：
/usr/lib/python2.7/site-packages/supervisor/
-》/etc中就找不到默认的配置文件supervisord.conf了。
然后由于此处
/etc/supervisord.conf
最后是：include包含ini文件，所以改为希望的conf：
<code>[include] ;files = supervisord.d/*.ini files = /etc/supervisord.d/*.conf </code>
接着，去创建一个项目的supervisor的配置文件，如下：
supervisord_robotDemo.conf
<code>[program:robotDemo] command=/root/.local/share/virtualenvs/robotDemo-dwdcgdaG/bin/gunicorn -c gunicorn_config.py app:app directory=/root/naturling_20180101/web/server/robotDemo startsecs=0 stopwaitsecs=0 autostart=true autorestart=true killasgroup=true stopasgroup=true stdout_logfile=/root/naturling_20180101/web/server/robotDemo/logs/supervisor-%(program_name)s-stdout.log stdout_logfile_maxbytes=2MB stdout_logfile_backups=10 stderr_logfile=/root/naturling_20180101/web/server/robotDemo/logs/supervisor-%(program_name)s-stderr.log stderr_logfile_maxbytes=2MB stderr_logfile_backups=10 </code>
然后再去：
<code>systemctl start supervisord </code>
即可正常启动。
添加到开机启动：systemctl enable supervisord
注意：此处估计是CentOS中通过yum去install，属于通过系统包管理工具去安装，所以默认帮忙生成好了对应的supervisord.service，所以才能直接用systemctl去管理的。否则估计要自己建立对应的supervisord.service文件，并配置合适的参数，加到合适的位置，才可以实现开机启动。
其他管理命令：
重新启动：systemctl restart supervisord
停止：systemctl stop supervisord
查看状态：systemctl status supervisord
当然也可以通过supervisorctl去管理：
查看状态：supervisorctl status all
全部停止：supervisorctl stop all
（当配置文件或文件本身更改后，想要重新加载）：supervisorctl reload
