where the file is located, and then read the file.2. The execution of php files does not require the execution permission of the files. You only need the read permission of the nginx and php-fpm running accounts.3. Whether a folder can be listed after a trojan is uploaded depends on the folder read permission of the php-fpm running account.4. the permission to run commands on trojans depends on the account

floating point type is 1010.10101. Similar to decimal, each digit has a corresponding weight. Only the digits after the decimal point. For example, 0.1 indicates 1/2 = 0.5, 0.01 indicates 1/4 = 0.25, and 0.11 indicates 1/2 + 1/4 = 0.75, at last, we can only extend the number to infinitely close to 0.1. If you want to

port like php-cgi for unified management and load balancing, it can save a lot of deployment effort. When I saw uWSGI, I found that I never knew that it was so convenient to deploy the tool in a unified manner. UWSGI, neither wsgi nor fcgi, is a self-built uwsgi protocol. It is said that the Protocol is about 10 times faster than the fcgi protocol. For more information, see: UWSGI has the following features: ◆ Ultra-fast performance. ◆ The low memor

From the code structure, nginx can be divided into three parts: infrastructure, concurrency model and application module. We have introduced the modular design of nginx and analyzed the nginx concurrency model. The concurrency model is mainly implemented by the core class module and event class module. The application module mainly refers to the HTTP and mail mod

for large chunks of data . The b-tree algorithm reduces the intermediate process that is experienced when locating records, thus speeding up the access speed. Widely used in databases and file systems . ”DefinedA B-tree can be seen as an extension of the 2-3 lookup tree, that is, he allows each node to have M-1 child nodes. Root node has at least two child nodes Each node has a M-

Java data structure and algorithm analysis (10)--2-3 Tree Binary lookup trees are efficient in most cases of finding and inserting, but they are less efficient in the worst cases. The data structure of the balanced lookup tree guarantees LGN efficiency in the worst-case scenario, and to achieve this we need to ensure that the tree remains in balance after the insert completes, which is the balanced lookup
