Please read this sentence carefully if the parent class has a private property. Then the parent class's method is only a private property service for the parent class. Here's a list of the following to deepen your understanding. This example looks strange, redefining an attribute $sal in a subclass, and the system returns the properties of the parent class. Copy CodeThe code is as follows: Class employee{ Private $sal = 3000; protected $sal = 3000; Public Function Getsal () { return $this->sal

. Symmetric Nat does not guarantee the consistency between the private and public IP addresses in all sessions. Instead, it assigns a new port number for each new session. The full name of the STUN Protocol is simple traversal of user datateprotocol through network address translators. The main function is to check whether it is behind Nat. If it is behind Nat, what is the address and port after Nat translation? In addition, you can check the NAT type. Now machine A is connected to machine B.

optimizer can automatically optimize queries based on the where clause, it is still necessary for you to understand the working principle of the "query optimizer". If not, sometimes the query optimizer does not perform quick queries according to your intention. In the query and analysis phase, the query optimizer checks each stage of the query and determines whether the data volume to be scanned is useful. If a phase can be used as a scan parameter (SARG), it is called an Optimized phase and th

The previous section learned and practiced the foundation and installation of Docker, and this section mainly studies the main concepts and commands of Docker Docker has three core concepts: Mirroring, container, warehouse one, mirroring Docker mirroring is a precondition for running a container, and if there is no mirror locally, Docker will attempt to download from the default Mirror warehouse (Docker hub), and users can configure their own private warehouses to download mirrors from a private

Docker Public Mirror Market https://hub.docker.com/Warehouses (Repository) are places where images are centrally stored, divided into public warehouses and private warehouses. The registration service is the specific server that holds the warehouse, a registration service can have multiple warehouses, and each warehouse can have multiple mirrors. For example, warehouse address Private-docker.com/ubuntu, private-docker.com is the registered server address, Ubuntu is the warehouse name. Speed Clo

Label: docker Although the official docker hub of docker provides a lot of images, it basically includes what we need to use, but its access is slow. If you want to customize the image, sharing among multiple servers is inconvenient to use this image. At this time, we urgently need a local private warehouse. The following figure illustrates the role of a private docker repository. The docker private repository can be implemented through the docker-registry project and uploaded and down

is actually equivalent to the sudo docker pull registry.hub.docker.com/ubuntu:12.04 command, which is downloaded from the Ubuntu repository in the registry server registry.hub.docker.com to 1 2.04 of the image.Sometimes the official warehouse registration server download is slow and can be downloaded from other warehouses. You need to specify the full warehouse registration server address when downloading from another warehouse. For example$ sudo docker pull dl.dockerpool.com:

Run containers based on private repository Images By default, the repository is stored in the/tmp/registry directory of the container. If the container is deleted, the image stored in the container will also be lost, therefore, we usually specify a local directory to be mounted to the/tmp/registry directory of the container! · The default storage path
