supervisor 從安裝到使用

(轉)https://www.jianshu.com/p/3658c963d28b

1、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版本爲python2.7 # python2.7 setup.py install #本地python版本爲python3以上 

2、配置

1.生成配置文件

echo_supervisord_conf > /etc/supervisord.conf 

2.啓動

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，配置以下：

cd /etc/supervisor vim ossfs.conf # 這裏的文件名稱自定義 

加入如下內容：

; 設置進程的名稱，使用 supervisorctl 來管理進程時須要使用該進程名
[program:your_program_name] 
command=python server.py --port=9000 ;numprocs=1 ; 默認爲1 ;process_name=%(program_name)s ; 默認爲 %(program_name)s，即 [program:x] 中的 x directory=/home/python/tornado_server ; 執行 command 以前，先切換到工做目錄 user=oxygen ; 使用 oxygen 用戶來啓動該進程 ; 程序崩潰時自動重啓，重啓次數是有限制的，默認爲3次 autorestart=true redirect_stderr=true ; 重定向輸出的日誌 stdout_logfile = /var/log/supervisord/tornado_server.log loglevel=info 

這裏是啓動要配置的參數，請根據本身的項目自定義添加

更改了supervisor配置文件，須要重啓,運行如下指令：

supervisorctl reload

4.supervisorctl的用法

supervisord : 啓動supervisor
supervisorctl reload :修改完配置文件後從新啓動supervisor
supervisorctl status :查看supervisor監管的進程狀態
supervisorctl start 進程名 ：啓動XXX進程
supervisorctl stop 進程名 ：中止XXX進程
supervisorctl stop all：中止所有進程，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，啓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啓

5.若不使用控制檯來管理進程，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

3、設置開機啓動

vim /etc/init.d/supervisord

添加如下腳本

#! /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.

# 設置該腳本爲能夠執行 sudo chmod +x /etc/init.d/supervisord # 設置爲開機自動運行 sudo update-rc.d supervisord defaults # 試一下，是否工做正常 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
