问题 I am using the exec command as below in PHP : exec("/usr/bin/php /path/to/Notification.php >> /path/to/log_file.log 2>&1 &"); In my local environment (MAMP), I know the PHP installation path, so I can replace /usr/bin/php with /Applications/MAMP/bin/php/php5.4.10/bin/php . But I don't know where the PHP installation (PHP binary) is located on the production server. 回答1: It's usually /usr/bin/php but you could try to capture and parse the output of the command ' whereis php ' or ' which php' '

问题 I'm using Apache Commons Pool library to maintaing a pool of couchbase connections (can be seen as any kind of connection, doesn't really matter). The problem I'm facing is that the only way I've found to return objects to the pool is to do it programmatically by calling the returnObject method from the GenericObjectPool class. This forces the application to guarantee the return of the object once is borrowed from the pool, regardless any exception or unexpected behavior in the application.

问题 In Grunt or Gulp, I used to define all the requirements myself, like: stuff should be minified only for production, livereload should be enabled only in dev server. Webpack handles this on its own, via its -d and -p options, that toggle the loaders' minimize mode (most loaders ship with their relevant minifiers), the devtool and similar stuff (I don't know what exactly). Most of that "just works". But on the other hand, there are some libraries that have a development and production mode. For

问题 I am trying to deploy code using Capistrano, and it fails on deploy:start or deploy:stop because the Unicorn process is already killed. However if I try to cap deploy:start , I get a stderr claiming that Address already in use - /tmp/my_app.socket . How would this happen, and how might I get out of this mess? 回答1: Still not sure how this happens, but the following solution seems to work: lsof /tmp/my_app.socket - lists the pids kill -9 pid - (replace 'pid' with one of those listed) Then cap

问题 I am attempting to solve performance issues with a large and complex tomcat java web application. The biggest issue at the moment is that, from time to time, the memory usage spikes and the application becomes unresponsive. I've fixed everything I can fix with log profilers and Bayesian analysis of the log files. I'm considering running a profiler on the production tomcat server. A Note to the Reader with Gentle Sensitivities: I understand that some may find the very notion of profiling a

问题 I am using play framework with java to develop a web application. I have wanted to read a file at the run time and the file has been included in a folder in the project. But at the production environment the folder is not available. Is there a way to make the folder available at the run time? And specially, is there a default method in play to handle such a scenario? I went through the question "How to read a file in Play Framework 2.2.1?1" But there is no mention about the problem in the

问题 Closed . This question needs to be more focused. It is not currently accepting answers. Want to improve this question? Update the question so it focuses on one problem only by editing this post. Closed 3 years ago . We have a linux production server and a number of scripts we are writing that we want to run on it to collect data which then will be put into a Spark data lake. My background is SQL Server / Fortran and there are very specific best practices that should be followed. Production

问题 I'm working on some open-source project and wouldn't like to keep URL of production servers in public repository with source code, but at the same time I'd like to have an opportunity to deploy using tomcat-maven-plugin. I tried to move server url from pom.xml to settings.xml, but it didn't work. Could You please give me a hint, what is the best way to keep url out of pom.xml? Thank You very much. Here is my configuration: settings.xml <settings> <servers> <server> <id>prod</id> <username

问题 I have written a little tool a few days ago (see Github project here) that works as a single .exe portable file. It is compiled/linked with: cl mytool.c I have uploaded the .exe on internet, but when people try to download it (direct link here), the file is seen as malware / potential threat, and thus can't be downloaded. ( Note that when disabling antivirus for 10 minutes, it is possible to download it successfully. ) How to compile/link my tool so that my .exe file is seen as potential
