Before looking at the signal, there is not much attention to the comparison of different signals. When I see it again today, I suddenly feel very similar to some of the signals, and even very easy to confuse. Let's take a moment to summarize this

Starting and stopping the database is the most basic operation of the database, and it is also a precondition for the database to provide service and be connected to management. There are some differences in the way the database starts and stops,

Before you introduce job management, you need to know that job management is used in the bash environment. This means "when the login system is acquired bash shell , under a single terminal interface, multiple jobs are managed simultaneously". It

The signal is the oldest of the process communication methods used by UNIX systems. Signals can be sent from the kernel to a single process, or from one process to another. For example, a user starts a program in the background to run for a long

LINUX Signal Concept DetailedWe run the following command to see a list of supported signals from Linux:# kill-l1) SIGHUP 2) SIGINT 3) Sigquit 4) SIGILL5) SIGTRAP 6) SIGABRT 7) Sigbus 8) SIGFPE9) SIGKILL (SIGUSR1) SIGSEGV) SIGUSR213) sigpipe)

The KILL command in Linux is used to terminate the operation of the specified process (terminate a process). Kill to send the specified information to the program. The preset information is sigterm (15), which terminates the specified program.(1)

Linux-Proficient KILL command 　　 No matter which operating system you use, you must encounter an application that is behaving erratically, locking itself down and refusing to shut down. On Linux (and Mac), you can force an end to it with a "kill"

One, can be reentrant function: Reentrant functions Follow the following three features. 1. A function cannot use any static or global variable that is not const. This is a better understanding, shared variables to ensure that can not be modified,

We're all looking through the error log.Inside the Rsyncd.log or the. err file, you can open the view with Notepad. Note that under Windows we need to give svcwrsync users the ability to manage all the permissions on the sync directory, basically.

Server normal operation 2 months, the day before yesterday the whole station suddenly appeared 502 bad Gateway, all pages are not open, using the NGINX+PHP-FPM mode.Server situation: This server traffic is relatively large, PV around 300,000 per day,

In the process of program development, we have to use a number of timers, usually if the time precision is not high, you can use the Sleep,uslepp function to allow the process to sleep for a period of time to achieve timing, The former unit is

The process of server shutdown can be summarized as follows: 1. Start and close the process 2. The server creates a thread to close the thread as needed. 3. The server stops receiving new connections. 4. The server terminates the current activity. 5.
