php - 如何在 Plesk 服务器中启动 HTTP 服务器时自动运行 WebSocket(socketo.me) 服务器

Question

我需要运行以 PHP 24/7/365 脚本编写的 PHP WebSocket

名为 websocket_server.php 的脚本的路径位于以下路径

/var/www/vhosts/abc.xy/httpdocs/proj_ci/application/libraries/websocket_server.php

为了首先运行上述脚本，它需要注册为服务并自动调用此命令。 我对在 Linux (Ubuntu 16.04) 中设置服务了解不多。所以我已经开始设置 crown 作业调度程序。但由于错误，它没有产生任何结果。

为了在任务调度程序中运行，我添加了三个命令，它们如下:

1. @reboot root nohup php /var/www/vhosts/abc.xy/httpdocs/proj_ci/application/libraries/server/websocket_server.php 2>&1 >/dev/null &

   
   Task "@reboot root nohup php /var/www/vhosts/abc.xy/httpdocs/proj_ci/application/libraries/websocket_server.php 2>&1 >/dev/null &" successfully completed in 0 seconds, output:
   -: @reboot: command not found
   

2. httpdocs/proj_ci/application/libraries/server/websocket_launch.sh with arguments cron:run

   
     Task "httpdocs/proj_ci/application/libraries/server/websocket_launch.sh" successfully completed in 0 seconds, output:
     PID=<code>ps -aef | grep "websocket_server.php" | grep -v grep | awk '{print $2}'</code>
     if [ -z $PID ]
     then<p></p>
     
     #echo "Launching now" nohup php websocket_server.php > error_log & else # echo "Running as PID $PID" fi
   

1. /usr/bin/php /var/www/vhosts/abc.xy/httpdocs/proj_ci/application/libraries/server/websocket_server.php

Task "/usr/bin/php /var/www/vhosts/abc.xy/httpdocs/proj_ci/application/libraries/server/websocket_server.php" completed with error in 0 seconds, output:
Could not open input file: /usr/bin/php /var/www/vhosts/abc.xy/httpdocs/proj_ci/application/libraries/server/websocket_server.php

这是来自 PuTTY 终端

root@h3069528:/var/www/vhosts/abc.xy/httpdocs/proj_ci/application/libraries# php /var/www/vhosts/abc.xy/httpdocs/proj_ci/application/libraries/server/websocket_server.php

root@h3069528:/var/www/vhosts/abc.xy/httpdocs/proj_ci/application/libraries/server#

除了增加 crown jobs 之外还有什么更好的方法吗？ 请尽可能帮助我解决问题。由于来自 PuTTY 终端， 我可以运行命令，一切正常

Answer 1

<?php 
# The maximum execution time, in seconds. If set to zero, no time limit is imposed.
set_time_limit(0);

# Make sure to keep alive the script when a client disconnect.
ignore_user_abort(true);

error_reporting(E_ALL);
ini_set('display_errors', 'On');
error_reporting(-1); // reports all errors
ini_set("display_errors", "1"); // shows all errors
ini_set("log_errors", 1);
ini_set("error_log", "/var/www/vhosts/abc.xy/httpdocs/websocket.log");

echo "Script start at: " . date('h:i:s') . "\n"; 
exec('bash -c "exec nohup php websocket_server.php >> /var/www/vhosts/abc.xy/httpdocs/websocket.log 2>&1 &"');
shell_exec('nohup php /var/www/vhosts/abc.xy/httpdocs/proj_ci/application/libraries/server/websocket_server.php 2>&1 >> /var/www/vhosts/abc.xy/httpdocs/websocket.log &');
echo "Script end at: " . date('h:i:s'); 
?>

这会将所有日志保存在给定的指定路径中 /var/www/vhosts/abc.xy/httpdocs/websocket.log

如果您从浏览器按名称访问指定的脚本，则上述脚本可以正常工作。如果服务器重新启动，您将能够在 Cron 作业中安排它

如果 exec() 方法在某些托管服务器中失败 shell_exec() 将正常工作而不会影响它是否已经在端口 8080 中启动
