services, greatly increased maintainability, This is one of the reasons why fcgi and other similar patterns are so popular.
However, it is because of this model, but also brings a number of problems. For example, the "Nginx File Parsing Vulnerability" released by 80sec last year is actually a problem because of fcgi and Webserver's understanding of the script path-level parameters. In addition, since fcgi and webserver are communicated through the network, more and more clusters will be fcgi di

Hadoop. tmp. DIR is the basic configuration that the hadoop file system depends on. Many Paths depend on it. Its default location is under/tmp/{$ user}, but the storage in the/tmp path is insecure, because the file may be deleted after a Linux restart.
After following the steps in the Single Node setup section of hadoop getting start, the pseudo-distributed file is running. How can I change the default hadoop. tmp. dir path and make it take effect? Follow these steps:
1. Edit CONF/core-site.
five bytes to the 5 bytes starting from the address of the original function (the function to be linked) in the memory. What does this mean? Some people may not know that 0xe9 is equivalent to the JMP command in the Assembly. (Of course, people who have a bit of disassembly basics know that 0xc3 = ret, 0xe9 = JMP, and many) in the Assembly, JMP is a jump command. Here, it is redirected to the position indicated by the next four bytes (our function address) to achieve the hook goal, this is why
