This article mainly introduces the use of automatic operation and maintenance tool clip, the article is very detailed, has a certain reference value, interested friends must read it!

Clip is an automated operation and maintenance tool, suitable for massive server management scenarios, can reduce the risk of system misoperation, improve work efficiency and so on.

Clip replaces the traditional IP management latitude with String management latitude. The change of management mode makes mass operation and maintenance more convenient, reliable and efficient. Clip is the Clip S architecture, which stores the IP relationship on the server side, and the client side can download SDK, traverse the IP and module relationship on the server side through SDK, and reorganize and rearrange the acquired IP module relationship locally, which is called Clip. On this basis, Clip also provides functions such as remote commands, file copy, IP organization tree traversal, historical command viewing, positive and negative parsing and import of String relations corresponding to IP. For the massive server operation and maintenance escort, lay the foundation.

The following is a detailed description of the following clip, an automatic exchange tool for operation and maintenance.

First of all, compared with String management, there are three advantages of String management:

1) the traditional management mode is IP. IP is composed of four groups of meaningless numbers, which is difficult to remember. Compared with the traditional way, String can see the name and meaning, and is convenient to remember.

2) when managing massive services, IP similarity often leads to operational failures, such as module A (10.131.24.37) and module B (10.117.24.37). The latter two digits are the same, and the two B modules are habitually considered to be module A, and sending configuration leads to online failure. This problem can be easily avoided through string management.

3) String can parse an IP or a set of IP, or reverse parse the String correspondence according to IP, which makes it more convenient for us to manage a group of services.

Let's take a look at the composition of String again. String is composed of (idc-product-modules-group) 4 segments. Students who know cmdb will find that its structure is very similar to that of cmdb. Level 4 module locates a service, but with the development of business, the author feels that level 4 service can no longer be located to a service. For example, when different business modules are mixed on a server, level 4 can only be located to the IP level of the service, but not to the real service. So Clip adds one level (idc-product-modules-group-port) on this basis, port port, through 5 segments to locate a service, which is also the advantage of Clip, flexible transformation to locate a group of services to meet business needs. Let's take another practical example. In the Shanghai computer room, module A uses port 80 to provide services, and module B uses port 8080 to provide services. At present, there are more than 100 machines, due to the decline in business traffic. In order to save resources, I currently want to merge the resources of the two modules, but the functions are not merged. We can represent two services into an impassable String, such as module A (sh-weixin-friend-a-80) and module B (sh-weixin-friend-b-8080). It is easy to separate the two services through String and deploy them on the same server to provide services.

We just introduced that Clip is Cramp S architecture. The IP relationship corresponding to String is stored in the server server. Client acquires IP through Clip's SDK. Its advantages are as follows:

1) after IP and String suggest a relationship, it can be called on all servers through SDK.

2) SDK provides other rich functions on the basis of parsing IP, such as scanning server, remote command, remote copy and so on.

3) Clip provides simple and clear API and SDK code structure and documentation, when Clip can not meet our needs, we can easily expand Clip through documentation to meet our needs.

Next, let's take a look at Clip SDK. Currently, there are eight subcommands in SDK:

The functions of each SDK subcommand are as follows:

◆ scan: used to scan the port survival status of the IP corresponding to String

◆ cstring: used to parse the IP corresponding to String and the String relationship corresponding to IP

◆ ssh: used to remotely execute system commands to IP corresponding to String

◆ scp: used to copy files remotely to IP corresponding to String

◆ tree: traversing child nodes under String

◆ history: displays commands executed in history

◆ import: import IP corresponding to String relationship

◆ lt: acquire IP relationships locally for management

◆ help: shows how many subcommands Clip has on the day.

*. Let's take a look at the application case to compare the differences of traditional vs clip management methods:

Traditional method: execute the uptime command on the 100servers of module A, the specific steps are as follows:

1) find the ip list of A modules to be synchronized

2) write a script to establish a connection with the server in the ip list

3) enter the account password when connecting to the server

4) copy files after successful account password verification

5) repeat the above steps for each IP.

Clip mode:

1) establish the correspondence between the ip list of module An and string, such as tj-qzone-qzoneini-access6

2) clip ssh-p password root@tj-qzone-qzoneini-access6 "execute command", the following is the structure.

Clip SDK usage

The Clip SDK function is used to obtain IP relationships on Server and to reorganize IP relationships on Client. (note: currently, clip also supports storing IP to local files for management.) Currently, Clip provides 8 subcommands, and the parameters of the following Clip SDK subcommands are explained and demonstrated (more case reference: Clipper case):
