HTTP**cow配置-折腾笔记

一、cow安装

请参考链接1

二、监控启动

监控工具:supervisor

[program:cow]
command=/home/pi/tools/cow/cow-linux-armv7l-0.9.8
directory=/home/pi/tools/cow
user=pi
autostart=true
autorestart=true
stopsignal=KILL
killasgroup=true
stopasgroup=true
redirect_stderr=true
stdout_logfile=/home/pi/tools/cow/cow.log
environment=HOME=/home/pi

如上所示。以前不能引导是因为少了HOME变量

以下全部作废:

配置:

[program:cow]
command=sudo -u root -H -- /usr/local/bin/cow  >/var/log/cow 2>&1 &
directory=/etc/cow
user=root
autostart=true
autorestart=true

启动配置:

#!/bin/bash
### BEGIN INIT INFO
# Provides:          cow
# Required-Start:    $network
# Required-Stop:     $network
# Default-Start:     2 3 4 5
# Default-Stop:      0 1 6
# Short-Description: COW: Climb Over the Wall http proxy
# Description:       Automatically detect blocked site and use parent proxy.
### END INIT INFO

# Put this script under /etc/init.d/, then run "update-rc.d cow defaults".

# Note: this script requires sudo in order to run COW as the specified
# user. Please change the following variables in order to use this script.
# COW will search for rc/direct/block/stat file under user's $HOME/.cow/ directory.
BIN=/usr/local/bin/cow
USER=root
GROUP=grp
PID_DIR=/var/run
PID_FILE=$PID_DIR/cow.pid
LOG_FILE=/var/log/cow

RET_VAL=0

check_running() {
  if [[ -r $PID_FILE ]]; then
    read PID <$PID_FILE
    if [[ -d "/proc/$PID" ]]; then
      return 0
    else
      rm -f $PID_FILE
      return 1
    fi
  else
    return 2
  fi
}

do_status() {
  check_running
  case $? in
    0)
      echo "cow running with PID $PID"
      ;;
    1)
      echo "cow not running, remove PID file $PID_FILE"
      ;;
    2)
      echo "Could not find PID file $PID_FILE, cow does not appear to be running"
      ;;
  esac
  return 0
}

do_start() {
  if [[ ! -d $PID_DIR ]]; then
    echo "creating PID dir"
    mkdir $PID_DIR || echo "failed creating PID directory $PID_DIR"; exit 1
    chown $USER:$GROUP $PID_DIR || echo "failed creating PID directory $PID_DIR"; exit 1
    chmod 0770 $PID_DIR
  fi
  if check_running; then
    echo "cow already running with PID $PID"
    return 0
  fi
  echo "starting cow"
  # sudo will set the group to the primary group of $USER
  sudo -u $USER -H -- $BIN >$LOG_FILE 2>&1 &
  PID=$!
  echo $PID > $PID_FILE
  sleep 0.3
  if ! check_running; then
    echo "start failed"
    return 1
  fi
  echo "cow running with PID $PID"
  return 0
}

do_stop() {
  if check_running; then
    echo "stopping cow with PID $PID"
    kill $PID
    rm -f $PID_FILE
  else
    echo "Could not find PID file $PID_FILE"
  fi
}

do_restart() {
  do_stop
  do_start
}

case "$1" in
  start|stop|restart|status)
    do_$1
    ;;
  *)
    echo "Usage: cow {start|stop|restart|status}"
    RET_VAL=1
    ;;
esac

exit $RET_VAL

三、问题

1、sudo: sorry, you must have a tty to run sudo错误。

表述:无法通过supervisor移动

来源:/var/log/cow日志文件

解决方法

使用不同账户,执行执行脚本时候sudo经常会碰到 sudo: sorry, you must have a tty to run sudo这个情况,其实修改一下sudo的配置就好了

vi /etc/sudoers (最好用visudo命令)

注释掉 Default requiretty 一行

#Default requiretty

意思就是sudo默认需要tty终端。注释掉就可以在后台执行了。-
