【已解决】CentOS中用supervisor去管理gunicorn的Flask的app

CentOS crifan 1426浏览 0评论

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:

[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)

</code>

然后对应的此处的其他logs,也是对的:

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

Server: Running supervisord automatically on startup for CentOS

</code>

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
