我正在測試通過Ubuntu上啓動 - 停止守護進程運行的簡單php腳本輸出的日誌記錄。從啓動 - 停止守護進程調用的php腳本記錄錯誤輸出
測試腳本,loop.php
的含量,如下所示:
<?php
while (true) {
error_log('Running at '.date('Y-m-d H:i:s').'...');
sleep(10);
}
當從命令行運行,如所預期到/tmp/loop.log
輸出被記錄:
php loop.php >> /tmp/loop.log 2>&1
即按預期工作,但現在我想通過start-stop-demon運行腳本。
我已經使用了example script作爲模板來進行設置:
#! /bin/sh
# Installation
# - Move this to /etc/init.d/myservice
# - chmod +x this
#
# Starting and stopping
# - Start: `service myservice start` or `/etc/init.d/myservice start`
# - Stop: `service myservice stop` or `/etc/init.d/myservice stop`

case "$1" in

echo -n "Starting ${DESC}: "
start-stop-daemon $START_OPTS >> $LOGFILE 2>&1
echo "$NAME."
;;
stop)
echo -n "Stopping $DESC: "
start-stop-daemon $STOP_OPTS
echo "$NAME."
rm -f $PIDFILE
;;
restart|force-reload)
echo -n "Restarting $DESC: "
start-stop-daemon $STOP_OPTS
sleep 1
start-stop-daemon $START_OPTS >> $LOGFILE 2>&1
echo "$NAME."
;;
*)
N=/etc/init.d/$NAME
echo "Usage: $N {start|stop|restart|force-reload}" >&2
exit 1
;;
esac
exit 0
我可以啓動和停止守護程序,一切按預期工作,但沒有東西寫/var/log/myservice.log
。
爲什麼腳本輸出沒有被記錄到指定的日誌文件?
