這篇文章主要介紹“supervisor的安裝和使用方法”,在日常操作中,相信很多人在supervisor的安裝和使用方法問題上存在疑惑,小編查閱了各式資料,整理出簡單好用的操作方法,希望對大家解答”supervisor的安裝和使用方法”的疑惑有所幫助!接下來,請跟著小編一起來學習吧!
一、安裝
源碼安裝
先下載最新的supervisor安裝包:https://pypi.python.org/pypi/supervisor , 如:
cd /usr/local/src wget https://pypi.python.org/packages/7b/17/88adf8cb25f80e2bc0d18e094fcd7ab300632ea00b601cbbbb84c2419eae/supervisor-3.3.2.tar.gz tar -zxvf supervisor-3.3.2.tar.gz cd supervisor-3.3.2 python setup.py install #本地python版本為python2.7 # python2.7 setup.py install #本地python版本為python3以上
二、配置
1.生成配置文件
echo_supervisord_conf > /etc/supervisord.conf
2.啟動
supervisord -c /etc/supervisord.conf
查看 supervisord 是否在運行:
ps aux | grep supervisord
3.配置
打開配置文件
vim /etc/supervisord.conf
在配置文件底部,配置include
[include] files=/etc/supervisor/*.conf #若你本地無/etc/supervisor目錄,請自建
用supervisor管理進程,配置如下:
cd /etc/supervisor vim ossfs.conf # 這里的文件名稱自定義
加入以下內容:
; 設置進程的名稱,使用 supervisorctl 來管理進程時需要使用該進程名 [program:your_program_name] command=python server.py --port=9000 ;numprocs=1 ; 默認為1 ;process_name=%(program_name)s ; 默認為 %(program_name)s,即 [program:x] 中的 x directory=/home/python/tornado_server ; 執行 command 之前,先切換到工作目錄 user=oxygen ; 使用 oxygen 用戶來啟動該進程 ; 程序崩潰時自動重啟,重啟次數是有限制的,默認為3次 autorestart=true redirect_stderr=true ; 重定向輸出的日志 stdout_logfile = /var/log/supervisord/tornado_server.log loglevel=info
這里是啟動要配置的參數,請根據自己的項目自定義添加
更改了supervisor配置文件,需要重啟,運行以下指令:
supervisorctl reload
4.supervisorctl的用法
supervisord : 啟動supervisor supervisorctl reload :修改完配置文件后重新啟動supervisor supervisorctl status :查看supervisor監管的進程狀態 supervisorctl start 進程名 :啟動XXX進程 supervisorctl stop 進程名 :停止XXX進程 supervisorctl stop all:停止全部進程,注:start、restart、stop都不會載入最新的配置文件。 supervisorctl update:根據最新的配置文件,啟動新配置或有改動的進程,配置沒有改動的進程不會受影響而重啟
5.若不使用控制臺來管理進程,用瀏覽器來管理,該如何配置?
打開配置文件
vim /etc/supervisord.conf
配置 inet_http_server
[inet_http_server] port=127.0.0.1:9001 ; 服務器ip username=xxx ;自定義 password=xxx ;自定義
三、設置開機啟動
vim /etc/init.d/supervisord
添加以下腳本
#! /bin/sh ### BEGIN INIT INFO # Provides: supervisord # Required-Start: $remote_fs # Required-Stop: $remote_fs # Default-Start: 2 3 4 5 # Default-Stop: 0 1 6 # Short-Description: Example initscript # Description: This file should be used to construct scripts to be # placed in /etc/init.d. ### END INIT INFO # Author: Dan MacKinlay <danielm@phm.gov.au> # Based on instructions by Bertrand Mathieu # http://zebert.blogspot.com/2009/05/installing-django-solr-varnish-and.html # Do NOT "set -e" # PATH should only include /usr/* if it runs after the mountnfs.sh script PATH=/usr/local/sbin:/usr/local/bin:/sbin:/usr/sbin:/bin:/usr/bin DESC="Description of the service" NAME=supervisord DAEMON=/usr/local/bin/supervisord DAEMON_ARGS=" -c /etc/supervisord.conf" #PIDFILE=/var/run/$NAME.pid PIDFILE=/tmp/$NAME.pid SCRIPTNAME=/etc/init.d/$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.

[ "$RETVAL" = 2 ] && return 2 # Wait for children to finish too if this is a daemon that forks # and if the daemon is only ever run from this initscript. # If the above conditions are not satisfied then add some other code # that waits for the process to drop all resources that could be # needed by services started subsequently.

# 設置該腳本為可以執行 sudo chmod +x /etc/init.d/supervisord # 設置為開機自動運行 sudo update-rc.d supervisord defaults # 試一下,是否工作正常 service supervisord stop service supervisord start
若報錯:insserv: warning: script 'service' missing LSB tags and overrides,請執行:
sudo apt-get remove insserv
