In accordance with an embodiment of the present invention, there is provided an embodiment of a command issuing method, it should be noted that the steps shown in the flowchart of the figure may be executed in a computer system such as a set of computer executable instructions, and that although a logical order is shown in the flowchart, in some cases, the steps shown or described may be executed in an order different from that here.
Fig. 1 is a flow chart of an alternative command issuing method according to an embodiment of the present invention. As shown in fig. 1, the method comprises the steps of:
step S102, a first server list is obtained, wherein the first server list lists all online first servers.
Step S104, a plurality of first commands are obtained, wherein the first commands are commands which need to be issued to a second type server by a first type server in a first type server list.
Step S106, traversing the first-class server list, and sequentially pushing a first command to the first-class servers, wherein one first command is pushed to one first-class server each time.
The first type of server may be a master and the second type of server may be a minus, the functions of the first type of server and the second type of server are different.
In the embodiment of the invention, the first command is a command which needs to be issued to the second server by the first server in the first server list, the first server list lists all online first servers, the first command is pushed to the first servers in sequence by traversing the first server list, wherein one first command is pushed to one first server at a time, after the first server receives the first command, the first command is issued to the second server, and the first commands pushed to the first servers are different, so that the first commands issued to the second servers by each first server are different, the problem that the second server repeatedly executes the same command is avoided, and the first servers work at the same time, the problem of resource waste caused by idle first servers is avoided, and the technical effect of improving the working efficiency of the multi-master architecture is achieved.
Optionally, the obtaining the plurality of first commands comprises: acquiring a second command to be issued, wherein the second command carries identification information of a plurality of second servers; and splitting each second command into a plurality of first commands, wherein each first command carries identification information of one second type server.
The number of the split first commands is equal to the number of the identification information of the second type server carried by the second commands.
The second command may be a command entered by the operation and maintenance personnel.
And splitting the second command into R first commands under the assumption that the second command carries the identification information of R second-class servers, wherein each first command carries the identification information of one second-class server.
The following examples illustrate:
a second command: salt-L 'mini 1, mini 2, mini 3' cmd.run "ipconfig"
The second command means that a command for executing the shell is issued to the time 1, time 2, and time 3.
Splitting the second command into 3 first commands:
1 st first command: salt 'finish 1' cmd.
Second command: run "ipconfig" in Salt 'finish 2' cmd.
The 3 rd first command: run "ipconfig" with Salt 'finish 3' cmd.
Wherein, the 1 st first command carries the identification information of a second type server (minus 1); the 2 nd first command carries identification information of a second type server (minus 2); the 3 rd first command carries identification information of a second type server (minus 3).
Optionally, there are N first-class servers in the first-class server list, and there are M first commands, traversing the first-class server list, and sequentially pushing the first commands to the first-class servers, where the method includes: sequencing the M first commands to obtain a 1 st first command, a 2 nd first command, a 8230command, an ith first command, an 8230command and an Mth first command; and pushing an ith first command to an ith first type server in the first type server list, wherein i sequentially takes 1 to M.
The following description is divided into two cases.
The first condition is as follows: n is greater than or equal to M, namely, the number of the first type servers is greater than or equal to the number of the first commands. In this case, the first-class server list is traversed, and a first command is pushed to each first-class server in sequence for distribution.
For example, as shown in table 1, there are 5 first type servers in the first type server list and 4 first commands. Pushing a 1 st first command to a 1 st first type server in the first type server list; pushing a 2 nd first command to a 2 nd first server in the first server list; pushing a 3 rd first command to a 3 rd first server in the first server list; and pushing a 4 th first command to a 4 th first server in the first server list.
TABLE 1
| A first command | First class server |
| 1 st first command | 1 st first type server |
| 2 nd first command | 2 nd first type server |
| 3 rd first command | 3 rd first type server |
| 4 th first command | 4 th first type server |
Case two: n is less than M, i.e., the number of first class servers is less than the number of first commands. In this case, the first-class server list is traversed, and a first command is pushed to each first-class server in sequence for distribution. And when the first-class server list is traversed and the first commands are not completely pushed, continuously traversing the first-class server list again, sequentially pushing a first command to each first-class server, and distributing until all the first commands are pushed to the first-class servers.
For example, as shown in table 2, there are 5 first-class servers in the first-class server list, and there are 12 first commands. Pushing a 1 st first command to a 1 st first type server in the first type server list; pushing a 2 nd first command to a 2 nd first server in the first server list; pushing a 3 rd first command to a 3 rd first server in the first server list; pushing a 4 th first command to a 4 th first server in the first server list; pushing a 5 th first command to a 5 th first server in the first server list; pushing a 6 th first command to a 1 st first type server in a first type server list; pushing a 7 th first command to a 2 nd first-class server in the first-class server list; pushing an 8 th first command to a 3 rd first-class server in a first-class server list; pushing a 9 th first command to a 4 th first type server in the first type server list; pushing a 10 th first command to a 5 th first-class server in the first-class server list; pushing an 11 th first command to a 1 st first-class server in a first-class server list; and pushing a 12 th first command to a 2 nd first server in the first server list.
TABLE 2
Optionally, the obtaining the first type server list includes: polling the IP in the first type server list; sending a test command to a target server to obtain a test result, wherein the target server is a first type server corresponding to the IP polled; and determining whether to update the first type server list according to the test result.
Optionally, determining whether to update the first server list according to the test result includes: if the test result indicates that the target server can work normally, keeping the first type of server list unchanged; and if the test result indicates that the working state of the target server is abnormal, deleting the target server from the first-class server list.
And after receiving the test command, the target server tests whether the target server can normally work to obtain a test result.
There are many methods for the target server to test whether it can work normally, and one of them is listed below. For example, a salt test command is sent to the target server, after the target server receives the salt test command, a simple HELLO test is performed on any one of the second type servers, and if the result is returned to True, it is proved that the target server can normally operate, that is, the test result indicates that the target server can normally operate, and in this case, the list of the first type servers is kept unchanged. And if the link returns to the Flase link or the ssh link cannot be carried out at all, the target server is proved to be incapable of working normally, namely the test result indicates that the working state of the target server is abnormal, and in this case, the target server is deleted from the first-class server list.
By deleting the first-class server with abnormal working state from the first-class server list, the first-class server list is updated in time, and the usability of the multi-master framework is guaranteed to be improved.
This scheme includes 4 parts:
1. available master list (first class server list)
The method is a list of server ip, records the ip of all available masters (first class servers) at present, and when a task needs to be issued, the task distribution module needs to rely on the list.
Master monitoring module
This module is an active monitoring program, the deployment location does not need to be specified, but the program needs to be put together with an "available master list", which continuously actively polls the IP in the available master list and sends a salt test command (i.e. the test command mentioned above) to the target machine (target server) through ssh, and judges the availability of the master by returning the result True or False or no response. Ping, which will cause the master to perform a simple HELLO test on any of the minions (servers of the second type), if True is returned, the master is certified as available, if either fiase or ssh link is returned, the master is considered as unavailable, and when an unavailable condition occurs, this module will update the "available master list" and delete the IP of the unavailable master from the list.
3. Task receiving module
The module is used as a use module of salt, when an operation and maintenance person needs to issue a task, the module is used to fill in a command to be issued and a target minus ion (a plurality of) lists, after the module receives the command, the module traverses the target minus ion list specified in the command, and changes the command (a second command) which is transmitted by the operation and maintenance and needs to be issued to a plurality of minus ions into a single salt '< traversed target machine >' cmd style small task (a first command) which is directed to a single minus ion. Examples are:
the commands input by the operation and maintenance personnel are as follows:
Salt-L 'finish 1, finish 2, finish 3' cmd.run "ipconfig" (second command)
The above-mentioned command means that the machine of minus 1, minus 2, minus 3 issues the command for executing shell
The commands after the disassembly of the modules are as follows:
salt 'creation 1' cmd.run "ipconfig" (first command)
Salt 'finish 2' cmd.run "ipconfig" (first command)
Salt 'finish 3' cmd.run "ipconfig" (first command)
All commands for single station Minion are obtained by disassembling, and all the commands (first commands) are transmitted to the task distribution module.
4. Task distribution module
And traversing the 'available master list' after obtaining all commands facing to the single station Minion, pushing one command by each master according to the sequence of the tasks for distribution, and continuing traversing until all the commands are pushed to the masters if the 'available master list' is traversed and the commands are not completely pushed.
The push uses ssh remote linking, which is not described here.
When a large amount of tasks need to be issued, only one machine works in a multi-master framework in the prior art, other machines are idle, a plurality of machines share the work together in the scheme, the execution efficiency is improved, and the fault master can be monitored, so that the tasks are not born, and the task loss is avoided.
