Ubuntu supervisor 启动脚本

2016年11月8日

此脚本主要是针对 pip   python 或者 easy_install  安装 的supervisor    ，  apt-get 安装的不需要会自动生成  ，其实这个就是apt-get 安装生成的。   不过注意一件事  pip   python 或者 easy_install  安装 的supervisor  在 /usr/local/bin  为了适应此脚本需要做一个软连接到  /usr/bin/

  1. root@167646:/etc/init.d# ln -s /usr/local/bin/supervisord /usr/bin/
  2. root@167646:/etc/init.d# ln -s /usr/local/bin/supervisorctl /usr/bin/

cat  /etc/init.d/supervisor

  1. #! /bin/sh
  2. #
  3. # skeleton      example file to build /etc/init.d/ scripts.
  4. #               This file should be used to construct scripts for /etc/init.d.
