我已经用 centos 在 ec2 rails 服务器上部署了我的网站。 ec2服务器重启时如何运行sidekiq？我关注了这个http://dxta.github.io/blog/2014/03/06/init-script-for-sidekiq-in-centos/，我写了一个如下所示的 bash 脚本，但 sidekiq 没有按预期重新启动

"#! /bin/bash
#
# sidekiq Init script for sidekiq

# chkconfig: 345 99 1

return $RETVAL
  else
    echo "$SIDEKIQ message processor is already running .. "
  fi


}

stop() {

    echo "Stopping $SIDEKIQ message processor .."
    SIG="INT"
    kill -$SIG `cat  $PID_FILE`
    RETVAL=$?
    [ $RETVAL -eq 0 ] && rm -f $LOCK_FILE
    return $RETVAL
}
status() {

  ps -ef | grep 'sidekiq [0-9].[0-9].[0-9]' | grep -v grep
  return $?
}

restart() {
  stop
  start
}

reload() {
  restart
}

force_reload() {
case "$1" in
    start)


    stop)


    restart)
  ;;
    reload)
  ;;
    force_reload)
  ;;
    status)

       status

        if [ $? -eq 0 ]; then
         echo "$SIDEKIQ message processor is running .."
         RETVAL=0
     else
         echo "$SIDEKIQ message processor is stopped .."
         RETVAL=1
     fi

*)

    exit 0

esac
exit $RETVAL

目前我正在手动运行 sidekiq。 bundle exec sidekiq -q mailer -q default -e qa -d -L /home/ec2-user/www/sps_qa/current/log/sidekiq.log 2>&1

【解决方案1】：

创建一个 upstart 作业，以便在引导期间触发 sidekiq。 sidekiq wiki 中有一个示例。更改参数以匹配您的参数。 https://github.com/mperham/sidekiq/blob/master/examples/upstart/manage-one/sidekiq.conf
