一陈惰、安裝
下載最新的supervisor安裝包：https://pypi.python.org/pypi/supervisor
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
Tips：錯(cuò)誤1：ImportError: No module named setuptools
## 下載pip
wget https://files.pythonhosted.org/packages/c2/f7/c7b501b783e5a74cf1768bc174ee4fb0a8a6ee5af6afa92274ff964703e0/setuptools-40.8.0.zip
unzip setuptools-40.8.0.zip
cd setuptools-40.8.0
python setup.py install
Tips：錯(cuò)誤2：error: Could not find suitable distribution for Requirement.parse(‘meld3>=0.6.5‘)畦徘，安裝meld擴(kuò)展
wget https://pypi.python.org/packages/45/a0/317c6422b26c12fe0161e936fc35f36552069ba8e6f7ecbd99bbffe32a5f/meld3-1.0.2.tar.gz#md5=3ccc78cd79cffd63a751ad7684c02c91
tar zxvf meld3-1.0.2.tar.gz
cd meld3-1.0.2
python setup.py install
Tips：本地python版本為python3以下
二、配置
1.生成配置文件
echo_supervisord_conf > /etc/supervisord.conf
2.啟動(dòng)
supervisord -c /etc/supervisord.conf
##查看 supervisord 是否在運(yùn)行：
ps aux | grep supervisord
3.基礎(chǔ)配置
（1）打開配置文件
vim /etc/supervisord.conf
（2）在配置文件底部抬闯，配置include
[include]
files=/etc/supervisor/*.conf #若你本地?zé)o/etc/supervisor目錄井辆，請(qǐng)自建
（3）用supervisor管理進(jìn)程，配置如下：
cd /etc/supervisor
vim ossfs.conf # 這里的文件名稱自定義
（4）加入以下內(nèi)容：
; 設(shè)置進(jìn)程的名稱溶握，使用 supervisorctl 來管理進(jìn)程時(shí)需要使用該進(jìn)程名
[program:your_program_name]
command=python server.py --port=9000
;numprocs=1 ; 默認(rèn)為1
;process_name=%(program_name)s ; 默認(rèn)為 %(program_name)s杯缺，即 [program:x] 中的 x
directory=/home/python/tornado_server ; 執(zhí)行 command 之前，先切換到工作目錄
user=oxygen ; 使用 oxygen 用戶來啟動(dòng)該進(jìn)程
; 程序崩潰時(shí)自動(dòng)重啟睡榆，重啟次數(shù)是有限制的萍肆，默認(rèn)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
（5）這里是啟動(dòng)要配置的參數(shù)，請(qǐng)根據(jù)自己的項(xiàng)目自定義添加
更改了supervisor配置文件胀屿，需要重啟,運(yùn)行以下指令：
supervisorctl reload
（6）服務(wù)啟動(dòng)
supervisord -c /etc/supervisord.conf
（7）用瀏覽器來管理進(jìn)程配置
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(wù)器ip
username=username ;自定義
password=password ;自定義
三塘揣、supervisorctl的用法
supervisord : 啟動(dòng)supervisor
supervisorctl reload :修改完配置文件后重新啟動(dòng)supervisor
supervisorctl status :查看supervisor監(jiān)管的進(jìn)程狀態(tài)
supervisorctl start all | 進(jìn)程名 ：?jiǎn)?dòng)全部或某進(jìn)程
supervisorctl stop all | 進(jìn)程名 ：停止全部或某進(jìn)程
supervisorctl stop all：停止進(jìn)程，注：start宿崭、restart亲铡、stop都不會(huì)載入最新的配置文件。
supervisorctl update：根據(jù)最新的配置文件葡兑，啟動(dòng)新配置或有改動(dòng)的進(jìn)程奖蔓，配置沒有改動(dòng)的進(jìn)程不會(huì)受影響而重啟
四、設(shè)置開機(jī)啟動(dòng)
（1）添加開機(jī)腳本
vim /etc/init.d/supervisord
腳本如下：
#! /bin/sh

（2）設(shè)置該腳本為可以執(zhí)行
sudo chmod +x /etc/init.d/supervisord
（3）設(shè)置為開機(jī)自動(dòng)運(yùn)行
sudo update-rc.d supervisord defaults
（4）試一下讹堤，是否工作正常
service supervisord stop
service supervisord start
若報(bào)錯(cuò)：insserv: warning: script 'service' missing LSB tags and overrides吆鹤，請(qǐng)執(zhí)行:
sudo apt-get remove insserv
五、錯(cuò)誤排查
1洲守、unix:///var/run/supervisor/supervisor.sock no such file
問題描述：安裝好supervisor沒有開啟服務(wù)直接使用supervisorctl報(bào)的錯(cuò)
解決辦法：?jiǎn)?dòng)服務(wù)
supervisord -c /etc/supervisord.conf
2疑务、啟動(dòng)了多個(gè)supervisord服務(wù)，導(dǎo)致無法正常關(guān)閉服務(wù)
問題描述：多次運(yùn)行supervisord -c /etc/supervisord.conf 或supervisord岖沛，導(dǎo)致有些進(jìn)程被多個(gè)superviord管理暑始，無法正常關(guān)閉進(jìn)程。
解決辦法：kill相關(guān)的進(jìn)程婴削。
ps -fe | grep supervisord #查看所有啟動(dòng)過的supervisord服務(wù)
kill -9 PID #kill相關(guān)進(jìn)程
3、supervisord 啟動(dòng)失敗 Error: Another program is already listening on a port that one of our HTTP serve...
unlink /var/run/supervisor.sock
unlink /tmp/supervisor.sock
這個(gè)錯(cuò)誤的原因就是supervisor.sock 這個(gè)文件會(huì)被系統(tǒng)自動(dòng)刪除或者其它原因不存在了牙肝，刪除軟連接就可以了唉俗。 supervisor.sock 生成的位置可以去 supervisor 的配置文件中找到嗤朴。
