问题 I run a flask app on uwsgi. I use supervisor to manage uwsgi process. I find the log saying that your server socket listen backlog is limited to 100 connections. How to overcome 100 connections limitation? My running script is as below: [program:myapp] command=uwsgi --master -s /tmp/app.sock --module myapp:app --processes 2 -H /srv/sites/mysite chmod-socket 666 --enable-threads 回答1: Note that a "listen backlog" of 100 connections doesn't mean that your server can only handle 100 simultaneous

Shut this program down first before starting supervisord. For help, use /usr/bin/supervisord -h 解决办法 Terminal上输入 ps -ef | grep supervisord 获取所有supervisord正在运行的pid root 2503 1 0 Nov19 ? 00:03:23 /usr/bin/python /usr/bin/supervisord root 21337 2556 0 18:15 pts/8 00:00:00 grep --color=auto supervisord pid=2503 kill -s SIGTERM 2503 之后在重新执行 supervisord -c /etc

一、添加好配置文件后 二、更新新的配置到supervisord supervisorctl update 三、重新启动配置中的所有程序 supervisorctl reload 四、启动某个进程(program_name=你配置中写的程序名称) supervisorctl start program_name 五、查看正在守候的进程 supervisorctl 六、停止某一进程 (program_name=你配置中写的程序名称) pervisorctl stop program_name 七、重启某一进程 (program_name=你配置中写的程序名称) supervisorctl restart program_name 八、停止全部进程 supervisorctl stop all 注意:显示用stop停止掉的进程,用reload或者update都不会自动重启。 来源: https://my.oschina.net/u/3371661/blog/3109088

Laravel Artisan Queues - high cpu usage

元气小坏坏 提交于 2019-11-30 04:56:14
I have set up queues in Laravel for my processing scripts. I am using beanstalkd and supervisord. There are 6 different tubes for different types of processing. The issue is that for each tube, artisan is constantly spawning workers every second. The worker code seems to sleep for 1 second and then the worker thread uses 7-15% cpu, multiply this by 6 tubes... and I would like to have multiple workers per tube.. my cpu is being eaten up. I tried changing the 1 second sleep to 10 seconds. This helps but there is still a huge cpu spike every 10 seconds when the workers wake back up. I am not even

Alternative to supervisord for docker

问题 Supervisord is really great tool even for docker environment. It helps a lot with stderr redirection and signals forwarding. But it has a couple of disadvantages: It doesn't support delayed startup. It could be useful to delay some agent startup until main app is initializing. Priority doesn't solve this issue. If some app enters FATAL state supervisord just logs it but continue to work. So you can't see it until look at logs of container. It could much more friendly if supervisord just stops

Supervisor 进程管理工具

简介 Supervisor 是基于 Python 的进程管理工具,可以帮助我们更简单的启动、重启和停止服务器上的后台进程,是 Linux 服务器管理的效率工具。什么情况下我们需要进程管理呢?就是执行一些需要以守护进程方式启动的程序,比如一个后台任务、一组 Web 服务的进程(说是一组,是因为经常用 Nginx 来做负载均衡),这些很可能是一些网站、REST API 的服务、消息推送的后台服务、日志数据的处理分析服务等等。注意:Supervisor 是通用的进程管理工具,可以用来启动任意进程,不仅仅是用来管理 Python 进程。 Supervisor 有两个主要的组成部分: 1 supervisord,运行 Supervisor 时会启动一个进程 supervisord,它负责启动所管理的进程,并将所管理的进程作为自己的子进程来启动,而且可以在所管理的进程出现崩溃时自动重启。 2 supervisorctl,是命令行管理工具,可以用来执行 stop、start、restart 等命令,来对这些子进程进行管理。 安装 sudo pip install supervisor 通过如上命令即可实现,需要注意的是如果你电脑既有python2和python3,那么需要使用 sudo pip3 install supervisor 配置文件 创建 echo_supervisord_conf >

supervisor主要由Supervisord、Supervisorctl、Web server和XML-RPC interface组成。 Supervisord:主进程,负责管理进程的server,它会根据配置文件创建指定数量的应用程序的子进程,管理子进程的整个生命周期,对crash的进程重启,对进程变化发送事件通知等。同时通过内置web server和XML-RPC Interface可以轻松实现进程管理。 Supervisorctl:管理client,用户通过命令行发送消息给supervisord,可以查看进程状态,加载配置文件,启停进程,查看进程标准输出和错误输出,远程操作等。 Web server:superviosr提供了web server功能,可通过web控制进程。 XML-RPC interface: XML-RPC接口,提供XML-RPC服务来对子进程进行管理和监控。 安装方法: >brew install supervisor >sudo npm install supervisor -g //mac 常用命令: # 启动supervisor >python /usr/bin/supervisord # 启动监控的进程 >supervisorctl start all # 关闭监控的进程 >supervisorctl stop all # 查看状态

1. 安装配置Supervisor supervisor是用Python开发的一个client/server服务,是Linux/Unix系统下的一个进程管理工具。 可以很方便的监听、启动、停止、重启一个或多个进程。用supervisor管理的进程,当一个进程意外被杀死, supervisor监听到进程死后,会自动将它重启,很方便的做到进程自动恢复的功能,不再需要自己写shell脚本来控制。 在Ubuntu17.04中安装Supervisor 首先保证本地的python环境是ok的,且python是2.x版本的,如有多个版本需要切换到2.x sudo apt-get install supervisor 基于python库安装 pip2 install supervisor easy_install supervisor 2. 安装成功后默认安装路径: /etc/supervisor supervisor文件夹下有supervisord.conf配置文件 upervisord.conf是一些默认配置,可自行修改: 配置自己的 Supervisor信息和目录路径: 打开/etc/supervisor/路径下的supervisord.conf文件。尾部找到如下文本片段: ;[include] ;files=/etc/supervisor/conf.d/*.conf 注意:[include
