supervisor的安装和使用方法

这篇文章主要介绍"supervisor的安装和使用方法"，在日常操作中，相信很多人在supervisor的安装和使用方法问题上存在疑惑，小编查阅了各式资料，整理出简单好用的操作方法，希望对大家解答"supervisor的安装和使用方法"的疑惑有所帮助！接下来，请跟着小编一起来学习吧！

一、安装

• 源码安装

先下载最新的supervisor安装包：https://pypi.python.org/pypi/supervisor ， 如：

cd /usr/local/srcwget https://pypi.python.org/packages/7b/17/88adf8cb25f80e2bc0d18e094fcd7ab300632ea00b601cbbbb84c2419eae/supervisor-3.3.2.tar.gztar -zxvf supervisor-3.3.2.tar.gzcd supervisor-3.3.2python setup.py install #本地python版本为python2.7# python2.7 setup.py install #本地python版本为python3以上

二、配置

1.生成配置文件

echo_supervisord_conf > /etc/supervisord.conf

2.启动

supervisord -c /etc/supervisord.conf

查看 supervisord 是否在运行：

ps aux | grep supervisord

3.配置

打开配置文件

vim /etc/supervisord.conf

在配置文件底部，配置include

[include]files=/etc/supervisor/*.conf #若你本地无/etc/supervisor目录，请自建

用supervisor管理进程，配置如下：

cd /etc/supervisorvim ossfs.conf # 这里的文件名称自定义

加入以下内容：

; 设置进程的名称，使用 supervisorctl 来管理进程时需要使用该进程名[program:your_program_name] command=python server.py --port=9000;numprocs=1                 ; 默认为1;process_name=%(program_name)s   ; 默认为 %(program_name)s，即 [program:x] 中的 xdirectory=/home/python/tornado_server ; 执行 command 之前，先切换到工作目录user=oxygen                 ; 使用 oxygen 用户来启动该进程; 程序崩溃时自动重启，重启次数是有限制的，默认为3次autorestart=true            redirect_stderr=true        ; 重定向输出的日志stdout_logfile = /var/log/supervisord/tornado_server.logloglevel=info

这里是启动要配置的参数，请根据自己的项目自定义添加

更改了supervisor配置文件，需要重启,运行以下指令：

supervisorctl reload

4.supervisorctl的用法

supervisord : 启动supervisorsupervisorctl reload :修改完配置文件后重新启动supervisorsupervisorctl status :查看supervisor监管的进程状态supervisorctl start 进程名 ：启动XXX进程supervisorctl stop 进程名 ：停止XXX进程supervisorctl stop all：停止全部进程，注：start、restart、stop都不会载入最新的配置文件。supervisorctl update：根据最新的配置文件，启动新配置或有改动的进程，配置没有改动的进程不会受影响而重启

5.若不使用控制台来管理进程，用浏览器来管理，该如何配置？

打开配置文件

vim /etc/supervisord.conf

配置 inet_http_server

[inet_http_server]       port=127.0.0.1:9001     ; 服务器ipusername=xxx        ;自定义password=xxx        ;自定义

三、设置开机启动

vim /etc/init.d/supervisord

添加以下脚本

#! /bin/sh### BEGIN INIT INFO# Provides:          supervisord# Required-Start:    $remote_fs# Required-Stop:     $remote_fs# Default-Start:     2 3 4 5# Default-Stop:      0 1 6# Short-Description: Example initscript# Description:       This file should be used to construct scripts to be#                    placed in /etc/init.d.### END INIT INFO# Author: Dan MacKinlay # Based on instructions by Bertrand Mathieu# http://zebert.blogspot.com/2009/05/installing-django-solr-varnish-and.html# Do NOT "set -e"# PATH should only include /usr/* if it runs after the mountnfs.sh scriptPATH=/usr/local/sbin:/usr/local/bin:/sbin:/usr/sbin:/bin:/usr/binDESC="Description of the service"NAME=supervisordDAEMON=/usr/local/bin/supervisordDAEMON_ARGS=" -c /etc/supervisord.conf"#PIDFILE=/var/run/$NAME.pidPIDFILE=/tmp/$NAME.pidSCRIPTNAME=/etc/init.d/$NAME# Exit if the package is not installed[ -x "$DAEMON" ] || exit 0# Read configuration variable file if it is present[ -r /etc/default/$NAME ] && . /etc/default/$NAME# Load the VERBOSE setting and other rcS variables. /lib/init/vars.sh# Define LSB log_* functions.# Depend on lsb-base (>= 3.0-6) to ensure that this file is present.. /lib/lsb/init-functions## Function that starts the daemon/service#do_start(){    # Return    #   0 if daemon has been started    #   1 if daemon was already running    #   2 if daemon could not be started    start-stop-daemon --start --quiet --pidfile $PIDFILE --exec $DAEMON --test > /dev/null \        || return 1    start-stop-daemon --start --quiet --pidfile $PIDFILE --exec $DAEMON -- \        $DAEMON_ARGS \        || return 2    # Add code here, if necessary, that waits for the process to be ready    # to handle requests from services started subsequently which depend    # on this one.

# 设置该脚本为可以执行sudo chmod +x /etc/init.d/supervisord# 设置为开机自动运行sudo update-rc.d supervisord defaults# 试一下，是否工作正常service supervisord stopservice supervisord start

若报错：insserv: warning: script 'service' missing LSB tags and overrides，请执行:

sudo apt-get remove insserv
