问题 Here is the situation... I have a cron job scheduled to run that is used to backup my database. Because of the way php is installed, I'm having to use lynx to hit the php script that is performing the backup. Because this script has to live within my public_html folder I want to deny all requests except for the ones that come directly from my server (i.e.: localhost). Also, I'm assuming that the ip I'll be coming from is 127.0.0.1. I'm not exactly sure if that's true but I can't think of what

阅读更多关于 kafka在windows下的安装和配置

博主最近在学习有关kafka的配置安装以及在spring的集成使用。但网上关于kafka的配置参考资料基本都是于linux下的配置，于是博主在整理了相关windows下kafka的配置记录在博客里。由于是简单配置所以在这里只建了一个topic以及一个producer和两个consumer。关于kafka具体是什么以及他的设计原理使用场景等等请看上篇博客，转自大佬。传送门： http://www.cnblogs.com/wdfordream/p/7324975.html 。在官网上下载 zookeeper和kafka( 我下的版本kafka_2.11-0.11.0.0，这个版本中bin目录下有windows目录 )，注意不要下载源码包（名字中带有src），否则启动的时候会报错。 1、配置好jdk环境 2、解压zookeeper到指定目录，找到解压后目录中conf文件夹中zoo_sample - 副本.cfg文件，复制在conf中改名为zoo.cfg。在bin文件夹中打开zkServer.bat启动zookeeper。至此，zookeeper启动完成。 3、解压kafka到指定目录。查看kafka根目录中config文件夹下server.properties，确认其中关于zookeeper的连接端口和zookeep中zoo.cfg的端口一致。　　3.1、启动kafka

问题 I'm new to the mac world and have just been setting up my webserver. I used the following guide: https://alan.ivey.dev/posts/2011/os-x-10.7-lion-development-native-mamp-with-mysql-installer/ I've transferred my sites and databases and everything is going pretty well.

Is it possible to run a socket server and socket client on the same machine?

阅读更多关于 Is it possible to run a socket server and socket client on the same machine?

问题 In java it is possible to create a socket server and a socket client, is it possible to have an instance of the socket server running and a socket/server client that is receiving data from the socket server on the same machine? e.g the socket server runs on port 60010 and the socket client is running on the same machine connecting to that port through a socket or will I need to by a new machine and add it to my network? If it has a unique IP Address and port number running on the TCP/IP layer

Test PHP's mail function from localhost

阅读更多关于 Test PHP's mail function from localhost

问题 I need to test a function that uses PHP's mail() How can I do this without uploading the script to a server and test it online? What's even more I am developing with no Internet connection at all. I am on Mac OSX running localhost from XAMPP. 回答1: You don't have to install an MTA on your computer to test PHP's mail() function. On Unix based systems (Linux, *BSD, OS X, etc.) you can set sendmail_path to something like tee mail.out > /dev/null . This will put the emails (including the headers)

问题 I'm trying to access the Deezer API from localhost, but I'm keep getting the following error: Fetch API cannot load http://api.deezer.com/search/track/autocomplete?limit=1&q=eminem. Response to preflight request doesn't pass access control check: No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'http://localhost' is therefore not allowed access. If an opaque response serves your needs, set the request's mode to 'no-cors' to fetch the resource with CORS
