session保存在redis内,多出来好多记录

Jun 06, 2016 pm 08:09 PM
php redis session

我在php.ini中更改了

<code>session.save_handler = files    ->    session.save_handler = redis
session.save_path = "/tmp"    ->    session.save_path = "tcp://127.0.0.1:6379"</code>
Copy after login
Copy after login

更改之后访问了一下,就突然多出这么多字段,但是都没有值。
如下:
session保存在redis内,多出来好多记录

这东西到底是什么鬼。


不好意思没有讲清楚。这些东西是在没有访问的情况下保存的,我完全没有访问服务器,又多了三个。


顺便提问一下,这样设置的session最后可以自动释放吗?过期时间到了之后会自动删除吗?

session_id

你再看看phpini里面session.autostart配置的是啥。
如果这个配置成1了,你不调用session_start系统会自动帮你调用会生成session ID,你不存东西,自然就是空的

可以查看 session 的配置 (http://php.net/manual/zh/session.configuration.php) 了解详细的情况
session 默认是有概率触发 gc 的,也就是垃圾回收
session 如果已经过期了,但是没有触发 gc, 那么还会存在着,等到下次 gc 的时候删去

至于你说的,没有访问服务器多了几条记录,你在仔细看看,确实发生了访问

php应该已经触发了,在mac中好像有其他东西在触发。

How to build the redis cluster mode How to build the redis cluster mode Apr 10, 2025 pm 10:15 PM

Redis cluster mode deploys Redis instances to multiple servers through sharding, improving scalability and availability. The construction steps are as follows: Create odd Redis instances with different ports; Create 3 sentinel instances, monitor Redis instances and failover; configure sentinel configuration files, add monitoring Redis instance information and failover settings; configure Redis instance configuration files, enable cluster mode and specify the cluster information file path; create nodes.conf file, containing information of each Redis instance; start the cluster, execute the create command to create a cluster and specify the number of replicas; log in to the cluster to execute the CLUSTER INFO command to verify the cluster status; make

How to implement the underlying redis How to implement the underlying redis Apr 10, 2025 pm 07:21 PM

Redis uses hash tables to store data and supports data structures such as strings, lists, hash tables, collections and ordered collections. Redis persists data through snapshots (RDB) and append write-only (AOF) mechanisms. Redis uses master-slave replication to improve data availability. Redis uses a single-threaded event loop to handle connections and commands to ensure data atomicity and consistency. Redis sets the expiration time for the key and uses the lazy delete mechanism to delete the expiration key.
