php ini change local value

由 巧了我就是萌 提交于 2019-12-10 10:39:13
问题 I just setup php55 with apache on CentOS. I am also running Couchbase to handle memcached sessions. I have one server running fine. The other keeps trying to save php sessions locally. Not sure why. The php config has session.save_handler=memcached and session.save_path="cb.path:11211" The phpinfo page still lists the temp session path as the "local" option and the handler to files, but get_session_save_path() returns the couchbase url. How do I find where the local value is being set? 回答1:

Couchbase Server （前身是 Membase） 是一个分布式的面向文档的 NoSQL 数据库管理系统，该系统联合了 CouchDB 的简单和可靠以及 Memcached 的高性能。 网上有MongoDB与Couchbase的对比，请参考： http://www.infoworld.com/d/data-management/nosql-showdown-mongodb-vs-couchbase-214912 Couchbase主页： http://www.couchbase.com/ 本文的目标是搭建简单的Couchbase环境并用Java语言进行读写测试。 1.准备工作 1）下载 Couchbase Server ，本文用到的版本是 version 2.1.1 for win64 ，2.0在某些机器上装不上，内核问题。 2）下载 Java相关类库 相关下载链接： http://www.couchbase.com/download 2.安装Couchbase Server 1)安装过程很简单，在官网下载并安装即可。 2)安装完成后Couchbase Console程序会自动打开http://localhost:8091地址，这时候有可能会打不开，最有可能出现的问题就是端口被占用了。 （占用与否，可以用cmd查一下） 这时再打开http://localhost

问题 We have used Couchbase Server in our product. Its an Intranet application whose front end is pure JavaScript. We however use Erlang/OTP for the Business Logic, authentication ( Mnesia ), yaws web server and a bunch of other erlang libraries. Now, we are still using the Couch Base Single Server whose download has been removed from the Couch base site. We have found it very stable. In now, 5 months of running live, it has never gone down. We are running it on top of Ubuntu Server. So, our

What is the best document storage strategy in NoSQL databases?

由 六月ゝ 毕业季﹏ 提交于 2019-12-09 02:05:16
问题 NoSQL databases like Couchbase do hold a lot of documents in memory, hence their enormous speed but it's also putting a greater demand on the memory size of the server(s) it's running on. I'm looking for the best strategy between several contrary strategies of storing documents in a NoSQL database. These are: Optimise for speed Putting the whole information into one (big) document has the advantage that with a single GET the information can be retrieved from memory or from disk (if it was

问题 I am using Couchbase 5 and Go Lang 1.11 , trying to query results based on an exact value. The code below is finding rows with a status of "Available" and "Not Available". How can I make it only return "Available" rows? qp.And(cbft.NewConjunctionQuery( cbft.NewMatchQuery("Available").Field("status") )) 回答1: It will depend on how you analyze the input field, it would help to know what analyzer you are using, but I'll assume the default, "standard", analyzer for now. Don't use the default

Does the Couchbase REST API support NON-JSON data (binary data)

由 99封情书 提交于 2019-12-08 07:10:54
问题 I am storing c structures to couchbase, I am doing so so that I can read back these structures later and process directly, I am avoiding the steps of 1 )C structure - > JSON while storing and 2 )JSON -> C structure while retrieving. This is working well when I use lcb_get() and lcb_set() But I also need have a requirement for making hits to views using the REST model and lcb_make_http_request () call. So I was wondering how the lcb_make_http_request () will handle my non-JSON C structure ,
