upstart ubuntu php

我有下面的Upstart脚本。当我运行以下命令时 service worker-1 start ,一切都很完美。我可以看到跑步的工人 ps aux | grep php 。我也可以使用 service worker-1 stop 我需要重新启动/更新工作人员。但不幸的是,该脚本仅在重新启动时部分工作。脚本已执行(开始:作业已在运行:worker-1,当我尝试时 服务工作人员-1启动 )但我看不到任何带 ps辅助|grep php 当然 服务工作人员-1停止 返回 stop: Unknown instance: 你知道会出什么问题吗?

description "Starts/kills workers."
author "Jiri Mihal"
start on (started php5-fpm and started mysql)
stop on shutdown

pre-start script
    echo "[`date`] Workers started" >> /var/log/worker-1.log
    exec 2>>/var/log/worker-1.log
end script

post-start script
    echo $$ > /var/run/worker-1.pid
    for i in `seq 1 5`;
    do
        exec php /home/jiri/workers/dlapi.workers/workers/RpcWorkerLauncher.php Worker-1 >/dev/null 2>&1 &
    done
end script

post-stop script
    read -r FIRSTLINE < /var/run/worker-1.pid
    kill $(($FIRSTLINE + 2))
    kill $(($FIRSTLINE + 3))
    kill $(($FIRSTLINE + 4))
    kill $(($FIRSTLINE + 5))
    kill $(($FIRSTLINE + 6))
    rm /var/run/worker-1.pid
    echo "[`date`] Workers stopped" >> /var/log/worker-1.log
end script

上面的脚本几乎是正确的。主要问题是PHP脚本启动了RabbitMQ工作程序,但RabbitMQserver尚未就绪。

我做了一些额外的调整,下面是一个有效的解决方案:

description "Starts/kills workers."
author "Jiri Mihal"
start on (rabbitmq-server-running or started rabbitmq-server)
stop on (shutdown or rabbitmq-server-stopped or stopping rabbitmq-server)

env WORKER=Workername
env COUNT=5

pre-start script
    echo "[`date`] Workers started" >> /var/log/worker-$WORKER.log
end script

post-start script
    for i in `seq 1 $COUNT`;
    do
        exec php /home/jiri/workers/dlapi.workers/workers/RpcWorkerLauncher.php $WORKER >/dev/null 2>&1 &
        if [ $i = 1 ]; then
           echo $! > /var/run/worker-$WORKER.pid
        fi
    done
end script

post-stop script
    read -r PID < /var/run/worker-$WORKER.pid
    for i in `seq 1 $COUNT`;
    do
        kill $(($PID + $i - 1))
    done
    rm /var/run/worker-$WORKER.pid
    echo "[`date`] Workers stopped" >> /var/log/worker-$WORKER.log
end script
