supervisor 是用python開(kāi)發(fā)的進(jìn)程管理工具，可以用來(lái)把自己寫(xiě)的腳本變成進(jìn)程矫付，每時(shí)每刻不斷地跑炫乓，而中斷時(shí)又能自動(dòng)重啟，開(kāi)機(jī)運(yùn)行

1钥屈、安裝supervisor

下載安裝包

wget https://pypi.python.org/packages/31/7e/788fc6566211e77c395ea272058eb71299c65cc5e55b6214d479c6c2ec9a/supervisor-3.3.3.tar.gz
tar -xvf supervisor-3.3.3.tar.gz
cd supervisor-3.3.3
python setup.py install

2、配置文件

echo_supervisord_conf > /etc/supervisord.conf #創(chuàng)建一個(gè)默認(rèn)配置文件

編輯內(nèi)容如下

; Sample supervisor config file.
;
; For more information on the config file, please see:
; http://supervisord.org/configuration.html
;
; Notes:
;  - Shell expansion ("~" or "$HOME") is not supported.  Environment
;    variables can be expanded using this syntax: "%(ENV_HOME)s".
;  - Quotes around values are not supported, except in the case of
;    the environment= options as shown below.
;  - Comments must have a leading space: "a=b ;comment" not "a=b;comment".
;  - Command will be truncated if it looks like a config file comment, e.g.
;    "command=bash -c 'foo ; bar'" will truncate to "command=bash -c 'foo ".
