is also a good portrayal of TechTarget's findings on the Linux operating system of the data center last year ). Ubuntu's most popular industry is the technology and education sector, which of course is not surprising. On the other hand, most respondents said they are using Ubuntu to complete some key tasks and intend to increase the number of Ubuntu servers in the future. Although they do not rush to take action, they have realized that Ubuntu is a g

disk. If your site is mostly static content, you'd better use the Mod_cache option, if your memory is large enough, you can use the Mod_mem_cache option. The first option caches information on disk, and it works well when used with the Mod_include option, which saves its final version in the cache when you create a page. Use Mod_mem_cache to save cached content in a memory heap that can be shared by all Apache processes. Using faster disks or using RAID further can improve Apache access to disk

security reasons, the primary server does not allow any DNS servers to replicate data from its own zone, and by default only DNS servers in this zone are allowed to be secondary DNS servers. As the following illustration shows, switching to the "Zone copy" tab in the properties of the hexun.com zone, we find that the default setting is to allow zone replication,

In some cases you may want to run multiple servers on the same machine. For example, you may want to test a new MySQL version so that your existing production system settings are not disturbed, or you may want to provide a separate MySQL installation for different customers with an Internet service provider. If you want to run multiple servers, the easiest way to do this is to recompile the server with dif

Label:Let's take a look at a basic concept of replication. What is replication? replication is the distribution of multiple copies (replicas) of data to each server in the company, providing the same data for multiple servers through replication. This allows the user to access the same information on different servers. for an enterprise with a large number of users, replication can spread the load of use
