The word "if" as used herein may be interpreted as "at … …" or "when … …" or "in response to a determination", depending on the context.
In the related art, the Linux system may perform system initialization by using a/etc/inittab file, where the content of the file is as follows:
::sysinit:/etc/init.d/sysinit
::wait:-/usr/bin/startup
::respawn:/sbin/agetty
the Linux system program is divided into a kernel mode program and a user mode program. The kernel-state program can exist for a long time, and if a fault occurs, the Linux system is crashed and restarted, so that the life cycle of the kernel-state program can be considered as equal to that of the system.
When the Linux system is started, the kernel mode program is initialized first, then the/etc/inittab file is parsed, and the sysinit specified program is started, which can be generally used for the initialization of the file system. Then starting a program specified by wait, wherein the program can be generally used for recovering the configuration of the user mode module, and then starting a terminal monitor program which manages a console port; the console port is a common control port of a network/security device, and can be connected with the console port and the PC of the device by using a dedicated connection line, and then the console port can be taken over by a terminal simulation program of the PC terminal to manage the device, and the management interface is a command line interface. After the terminal monitor is started, the user can only execute the commands provided by the terminal monitor, but cannot execute the commands (such as ls, mv, rm, and the like) provided by the terminal monitor (such as a shell) of the Linux system.
When the terminal monitor exits for some reason (for example, the process crashes due to a failure, or is actively stopped by a kernel-state program, and the system maintenance personnel needs to restart the process in order to repair a local failure of the process), the program represented by the resume line is started, the program is generally a console login verification program (for example, agent), after the terminal program exits, the system is automatically switched to the program, in this case, the console port of the device and the PC need to be connected by a dedicated connection line through an administrator, the console port needs to be taken over by a terminal simulation program at the PC, then a login verification interface is displayed at the PC, the login is verified by using a user account and a password, and the terminal monitor program is restarted.
On one hand, after the terminal monitoring program exits, the PC and the console port of the device must be connected through a dedicated connection line, then the console port is connected through the terminal simulation program of the PC, and then a login verification interface is displayed on the PC, so that the management can perform login verification operation and recover the operation of the terminal monitoring program. Wherein, the availability is the probability that the system or a specific program can normally operate within a certain investigation time or the expected value of the time occupancy.
On the other hand, although the terminal listener is not exited, the process does not respond for some reason (for example, is attacked by a specific message), and the process cannot be operated through the console port, telnet, SSH (Secure Shell protocol), and the like.
In order to solve the problems in the related art, the application provides an initialization method of a Linux system, which is applied to terminal equipment carrying the Linux system, and a kernel mode program terminates a terminal monitor when the terminal monitor loses response; when the terminal monitoring program exits, the system automatically runs the respawn program; then, the respawn program judges whether the starting times of the terminal monitoring program in a preset period reach a preset threshold value; if the starting times reach a preset threshold value, starting a login verification program; and if the starting times do not reach the preset threshold value, restarting the terminal monitoring program.
On one hand, the automatic restart program of the system is changed into the self-defined respaw program, and the self-defined respaw program can start the terminal monitoring program, so that the program in the respaw can be automatically executed after the terminal monitoring program in the wait exits, and the terminal monitoring program can be automatically restarted, so that the condition that the terminal monitoring program can be restarted after the terminal program exits and an administrator is required to verify and log in can be avoided, and the purpose of improving the usability of equipment can be realized.
On the other hand, the automatic restart program respawn of the system is changed into the self-defined respawn program, the starting times of the terminal monitoring program can be checked in the self-defined respawn program, when the starting times of the terminal monitoring program exceed the preset threshold value, the system can terminate the terminal monitoring program, start the login verification program and wait for the processing of a system administrator, so that the situation that the system is busy in the state of infinitely restarting the terminal monitoring program to cause that the console port cannot carry out any operation when the terminal monitoring program has serious faults can be avoided, and the purpose of improving the usability of the equipment can be realized.
In addition, whether the terminal monitor is in a non-response state or not is judged by detecting whether the survival information periodically sent by the terminal monitor is received or not within the timing time through the kernel mode program. When the terminal monitor program is in a non-response state, the kernel-state program can terminate the terminal monitor program, and the terminal monitor program is automatically restarted through respawn, so that the condition that the terminal monitor program cannot provide service for a long time when the terminal monitor process has no response can be avoided, and the purpose of improving the equipment availability can be realized.
Referring to fig. 1, fig. 1 is a flowchart of an initialization method of a Linux system according to an exemplary embodiment of the present application, which is applied to a terminal device equipped with the Linux system, where a program specified by a respaw in an inittab file of the Linux system is modified into a custom respaw program (hereinafter, respaw program), and the following steps are specifically executed:
step 101: when the terminal monitoring program loses response, the kernel mode program terminates the terminal monitoring program; when the terminal monitoring program exits, the system automatically runs the respawn program;
step 102: the respawn program judges whether the starting times of the terminal monitoring program in a preset period reach a preset threshold value or not;
step 103: if the starting times reach a preset threshold value, starting a login verification program; and if the starting times do not reach the preset threshold value, restarting the terminal monitoring program.
In this embodiment, in order to avoid the problem of service interruption caused by the terminal monitor being unable to automatically restart after the terminal monitor exits abnormally, an initialization procedure of the existing Linux-based operating system may be modified, specifically, a login verification program specified by respawn in an inittab file of the Linux system may be modified into the terminal monitor.
For example, taking the Linux-based derivative operating system, Conplat, in which the terminal monitor is the Consplat _ cli, the sequence of respawn:/sbin/agent may be modified to respawn:/respawn _ conti, and when the Linux system is initialized, sysinit:/etc/init.d/sysinit is executed first, and after the program of the sysinit row is executed, wait:/usr/bin/startup is executed, and then the terminal monitor can take over the console port.
When the terminal listener exits due to some abnormal reasons (including forced termination by a kernel-mode program or a fault that causes self-termination of the terminal listener, such as a memory access error), in such a case, the system may automatically execute a program specified by respown, that is, the terminal listener. Therefore, the terminal monitoring program can be prevented from being restarted after the terminal program exits and the administrator is required to perform verification and login, and the purpose of improving the equipment usability can be achieved.
However, considering that the terminal listener itself may have a serious fault and cannot be started under a specific condition, the system is busy with infinitely restarting the terminal listener, so that the console port cannot perform any operation, and since the automatic restart of the terminal listener is automatically restarted by the system itself, the administrator cannot terminate, and once such a fault occurs, the system loses response and cannot manage.
In order to solve the above problem, the program designated by respawn may be modified to have a function of detecting the number of times the terminal listens to the start of the program.
When the initialization process of the Linux system runs to a program specified by respaw, the terminal monitoring program can be automatically restarted, then the respaw program can check whether the starting frequency of the terminal monitoring program reaches a preset threshold value or not since the system is started, when the starting frequency of the terminal monitoring program reaches the preset threshold value, the respaw program can terminate the automatic restart of the terminal monitoring program, the automatic restart is converted into a starting login verification program, and after a system administrator performs login verification and solves the problem, the automatic restart process of the terminal monitoring program is recovered.
For example, taking the Linux-based derivative operating system, in the conplay operating system, the terminal listener is a contit _ cli, and when the concst _ cli is implemented, the terminal listener can be modified to have a function of checking the boot frequency, the modified terminal listener is a contit _ respawn, a program specified by the respawn can be modified to be the terminal listener, and the boot frequency of the terminal listener can be checked through the modified terminal listener.
In an embodiment shown, the preset threshold may be a ratio of a duration corresponding to the preset period to a sum of a duration required for starting the terminal monitor and a duration for manually terminating the automatic restart of the terminal monitor by an administrator. The preset period is used for an inspection process of automatic restart of the terminal monitoring program.
When setting the threshold, whether the time length from the current start to the next start of the terminal monitor is enough to allow a system administrator to actively terminate the automatic restart of the terminal monitor through a command line needs to be considered, so that the duration of the automatic restart should be as short as possible, so that the administrator can terminate the automatic restart of the terminal monitor as soon as possible; also considering the problem of the availability of the device, if the preset threshold is small, it may cause the termination of the terminal listener after several occasional restarts, which may reduce the availability of the device, and therefore the preset threshold may not be too high, otherwise the administrator may not terminate the terminal listener by hand, nor too low, otherwise the availability of the device may be reduced.
For example, if the preset period is 600 seconds, the terminal listener start time needs 10 seconds, and the administrator manually terminates the automatic restart of the terminal listener time needs 20 seconds, the preset threshold cannot exceed 20[600/(10+20) ] times.
In an embodiment shown, when counting the number of times of automatic restart of the terminal monitor, a block of memory may be applied in the memory of the Linux system for storing the start time of the terminal monitor, where the block of memory may be in a kernel mode program or an independent memory at any position of a terminal device carrying the Linux system.
After the terminal monitor is started, the kernel mode program may generate a time record corresponding to the start time of the terminal monitor, add the start time record to the memory, and then count the number of times of starting the terminal monitor based on the number of time records recorded in the memory.
In this embodiment, after counting the number of times of starting the terminal monitor, the respawn procedure can determine whether the number of times of starting the terminal monitor reaches a preset threshold value in a preset period. If the starting times of the terminal monitoring program reach a preset threshold value, the restarting times of the terminal monitoring program are frequent at the moment, and the terminal monitoring program is likely to be infinitely restarted due to the fact that serious faults may exist in the terminal monitoring program, under the condition, the automatic restarting process of the terminal monitoring program can be stopped, and the login verification program can be started immediately; of course, if the number of times of starting the terminal monitor does not reach the preset threshold, the restart process of the terminal monitor can be normally executed, and the terminal monitor can be restarted.
In an embodiment shown, when the automatic restart process of the terminal monitor is terminated and the login verification program is started, the kernel-state program may further empty the generated time record corresponding to the time when the terminal monitor is started, and after the administrator repairs the fault, the terminal monitor may be restarted through the login verification and enter the next cycle.
Of course, except that the administrator manually terminates the automatic restart of the terminal monitor through the command line, and the respaw program terminates the automatic restart of the terminal monitor when the startup frequency of the terminal monitor reaches the preset threshold, the generated time record corresponding to the startup time of the terminal monitor can be also recorded and emptied after the whole Linux system is restarted.
In this case, besides the problem of the above-described unlimited restart, the terminal monitor program may also have an abnormal problem that the terminal monitor process has no response for unknown reasons. For this case, the following measures may be taken.
In one embodiment, the terminal listener may periodically send a survival signal to the kernel-mode program based on a preset period, where the preset period is used to determine whether the terminal listener is abnormal. Then, the kernel mode program may start a timer, and check whether the survival signal sent by the terminal monitor is received within a preset time period, and if the survival signal sent by the terminal monitor is not received within the preset time period, it may be determined that the terminal monitor is abnormal.
For example, if the preset period for the terminal listener to periodically send the alive signal to the kernel mode is 10 seconds, and the time duration for the kernel mode program to start is 100 seconds, the kernel mode program may determine that the terminal listener is abnormal if the kernel mode program does not receive the alive message sent by the terminal listener within the 100 seconds.
In an embodiment shown, when the kernel-state program determines that the terminal monitor program is abnormal, the kernel-state program may terminate the terminal monitor program, and then the kernel-state program may execute a custom reset-specified program to restart the terminal monitor program, and recover an automatic restart flow of the terminal monitor program.
According to the technical scheme provided by the application, when the terminal monitor loses response, the kernel mode program terminates the terminal monitor; when the terminal monitoring program exits, the system automatically runs the respawn program to restart the terminal monitoring program; then, the respawn program judges whether the starting times of the terminal monitoring program in a preset period reach a preset threshold value; if the starting times reach a preset threshold value, starting a login verification program; and if the starting times do not reach the preset threshold value, restarting the terminal monitoring program.
On one hand, the automatic restart program of the system is changed into the self-defined respaw program, and the self-defined respaw program can start the terminal monitoring program, so that the program in the respaw can be automatically executed after the terminal monitoring program in the wait exits, and the terminal monitoring program can be automatically restarted, so that the condition that the terminal monitoring program can be restarted after the terminal program exits and an administrator is required to verify and log in can be avoided, and the purpose of improving the usability of equipment can be further realized.
On the other hand, the automatic restart program respawn of the system is changed into the self-defined respawn program, the starting times of the terminal monitoring program can be checked in the self-defined respawn program, when the starting times of the terminal monitoring program exceed the preset threshold value, the system can terminate the terminal monitoring program, start the login verification program and wait for the processing of a system administrator, so that the situation that the system is busy in the state of infinitely restarting the terminal monitoring program to cause that the console port cannot carry out any operation when the terminal monitoring program has serious faults can be avoided, and the purpose of improving the usability of the equipment can be realized.
In addition, whether the terminal monitor is in a non-response state or not is judged by detecting whether the survival information periodically sent by the terminal monitor is received or not within the timing time through the kernel mode program. When the terminal monitor program is in a non-response state, the kernel-state program can terminate the terminal monitor program and automatically restart the terminal monitor program through respawn, so that the situation that the terminal monitor program cannot provide service for a long time when the terminal monitor process is blocked can be avoided, and the purpose of improving the equipment availability can be realized.
