terminal can be generated using the ANSI non-normal character sequence. Example:Echo-e "\033[44;37;5m ME \033[0m Cool"The above command sets the background to blue, the foreground is white, the blinking cursor, the output character "ME", and then reset the screen to the default settings, the output character "cool". "E" is an optional option for command Echo, which activates the parser for special characters. "\033" boots a sequence of unconventional
and running is not the end of the boot; This is only the first phase (sometimes called running level one, run levels 1). After running level one, the kernel back transfers control to a program called INIT, which starts some user processes. The first thing the Init process does is check the integrity of your disk. Disk file systems are very important; if they are due to a hardware problem or a sudden power outage, there is a good reason to check and fix them before the UNIX system

1. In a Linux system, access the device in a file format.
2. When the Linux kernel boots, read the file system to be loaded from the file/etc/fstab.
3. Each file in the Linux file system is identified by the I node.
4. All disk blocks are composed of four parts, namely, the boot block, the private block, the I node table block and the data storage block.
5. Links are divided into: hard links and symbolic links.

MySQL server with no privileged user account
Before discussing how to start the server, consider which account you should run when the server starts. The server can be started manually and automatically. If it is started manually, the server runs as a UNIX user (you are registered as that user). That is, if the author registers with Paul and starts the server, it will run as Paul. If you switch the user to root and then start the server with the S U command, the server runs as root.

can be done! The script is best to simply extend the Redis for smaller atomic operations and simple logical control needs, bugs in the Lua script can raise the entire Redis server lock-preferably keeping the script short and easy to debug.
While these scripts are generally short, we do not want to use the full Lua script every time we execute it, but we can actually register the Lua script (or register it when you deploy) in the program Step by step (application
A constant is the most basic element in a program and cannot be assigned again after it is defined. The constant types in the Go language are Boolean constants, integer constants, floating-point constants, Word constants, string constants, and complex constants.
Boolean Constants
Copy Code code as follows:
Const X = True
Fmt. Print (x)//Output True
Integer constants
Copy Code code as follows:
Const X = 20
Fmt. Print (x)//Output 20

very likely that you will schedule the server to run automatically as part of the standard boot process when the system boots. In Unix, the boot process is performed by the system as a UNIX R o T user, and any processes that are started in the process are run with root permissions.
You should keep in mind the two goals of the MySQL server startup process:
To start the server as some non-root user. Typically, you should limit the ability of any proces

To support remote access debugging, you need to annotate bind 127.0.0.1 in the configuration file, in addition to the need to open server port number 6379, but should be released from the production environment to avoid hacker attacks
