嗨，我正在创建一个新的 init 脚本来监视 ruby 程序。
NAME=differ
FILE_PATH=/home/amer/Documents/ruby_projects/differ/
PIDFILE=/home/amer/pid/differ.pid
PID=$$
EXEC='/home/amer/.rvm/rubies/ruby-2.0.0-p247/bin/ruby main_scheduler.rb'
do_start(){
echo "started"
cd $FILE_PATH
pwd
$EXEC >> init_log/output.log &
echo $! > $PIDFILE
echo "---------"
echo `cat $PIDFILE`
echo "all are DONE "
}
do_stop(){
PID=`cat $PIDFILE`
echo $PID
if ps -p $PID ; then
kill -6 $PID
echo "it is over"
else
echo "its not running"
fi
}
case "$1" in
start)
echo $$
echo -n "Starting script differ "
do_start
;;
stop)
echo "stopping ...."
do_stop
;;
status)
PID=`cat $PIDFILE`
echo "STATUS $PID"
if ps -p $PID -f; then
echo running
else
echo not running
fi
;;
restart|reload|condrestart)
do_stop
do_start
;;
*)
echo "Usage: /etc/init.d/blah {start|stop}"
exit 1
;;
esac
exit 0
我的监控过程是
check process differ with pidfile /home/amer/pid/differ.pid
if changed pid then exec "/etc/init.d/differ start"
start program = "/etc/init.d/differ start"
stop program = "/etc/init.d/differ stop"
if 5 restarts within 5 cycles then timeout
但是当我在我的监视器中执行启动服务时，状态是“执行失败”，我检查了监视器的日志文件，它说
info : 'differ' start: /bin/bash
error : 'differ' failed to start
error : 'differ' process is not running
当我分析问题的根源时。原因是 monit 以 root 身份运行，执行 ruby 的脚本将作为sudo /etc/init.d/differ.sh start执行，但 ruby 仅安装在用户 'amer' 中。我努力了
sudo -u amer $EXEC >>init_log/output.log &
它显示错误为
amer@amer-Inspiron-1525:~$ /home/amer/.rvm/rubies/ruby-2.0.0-p247/lib/ruby/2.0.0/rubygems/core_ext/kernel_require.rb:45:in `require': cannot load such file -- bundler/setup (LoadError)

from main_scheduler.rb:2:in `<main>'
请帮助解决这个问题。我有两个红宝石版本。
