In order to solve the problem that the cost of building a server system for small and medium-sized enterprises is too high, a solution is proposed to build a multi-function server system using free (open-source) software such as CentOS and MySQL. With Ghost technology, you can quickly install a multi-function server sy

As small and medium-sized enterprises develop to a certain stage, more servers are needed to support the operation as the business volume increases. For the choice of servers, small and medium-sized enterprises consider factors that are more detailed, trivial, and more practical than large enterprises. This is why many small and medium-sized enterprises use high-

of enterprise operations and the speed of market response. Compared with large enterprises, most small and medium-sized enterprises have disadvantages such as weak technical strength, reserve, small scale, and ability to withstand system disasters and risks. In addition, due to the competitive environment and cost pressure, the IT status of SMEs is also uneven. Therefore, it is necessary to establish a con

number of records in that bucket. That is, if there is a bucket, the first three barrels of record count is 10, and the number of the 4th Poke is 6, then the 5th and 6th barrels of records must also be 6.According to the above two conventions, the following algorithm can be obtained:MoD indicates the remainder, Div indicates roundingIf (total number of records mod barrels = = 0){RecordCount = total number of records div buckets;Set the number of records per bucket to RecordCount}Else{RecordCoun

In addition, the VPs server system itself and other programs will also use some memory, but the VPs with M memory is enough. In general, after optimization, the VPs
