Install, configure, and migrate FastDFSV3.02Background: We used fastdfsV3.02 on the original server, and now we want to migrate it to the new server. There are no relevant documents on the Internet and it has been a long time. Now we will record the migration process as follows to facilitate the configuration and migration of other students.Tracker server: 192.168.1.246 Storage Server: 192.168.1.246 Deploy tracker and storage on the same server when

). The direction of the packet can also be obtained by ctinfo/ip_ct_is_reply, but a more convenient macro ctinfo2dir (Ctinfo) can be used, defined in Connection Tracker The connection tracker is a very important part of the connection tracking architecture and relates to the implementation of the State firewall. Its main task is to find the corresponding connection information for an IP packet and ensure

1, picture access exception problem descriptionBuild a new environment of the Fastdfs file server, just set up the time, uploaded a picture, normal, but because the port is not open, there is no authentication access problem. The environment is being shelved for testing.Later in the test, because there are too many image files to upload, so directly copy the production environment DFS data directory, replace the data directory of the new environment, and the following files are still used in the

control services with Visual Studio, you must have VSS or an alternate provider installed on each source control client. Install the visual SourceSafe 6.0c as the MSSCCI provider to run Setup.exe from the root directory of the visual SourceSafe 6.0c version of the installation CD. After you install the source control provider, the next step is to create a source control database to store the server version of your team's shared files. Create a source control database The following procedure a

management is certainly not beyond it. However, as we have mentioned, the particularity of the open source software development model also puts forward new and stricter process requirements for its bug tracking and management process. In this case, it is necessary to have a more correct understanding of the defect tracking system (bug Tracker) first. Defects include product errors, requirements and design changes, new features or extensions (Feature,

A Brief introduction Fastdfs is an open-source lightweight Distributed File System , it manages files, including: file storage, file synchronization, file access (file upload, file download), and so on, to solve the problem of large-capacity storage and load balancing. Especially suitable for file-based online services, such as photo album sites, video sites and so on. The Fastdfs server has two roles: Tracker (

A: PT (Private Tracker) download is actually a BT download, but there are two obvious improvements: one is the private small-scale download, the second is to carry out traffic statistics, based on the amount of upload to determine your permissions.When BT downloads, The software will analyze the. torrent seed file to get the tracker address, and then connect to the trac
