100, the acquisition request of the Hadoop service page for the user that receiving front-end equipment is sent；
101, it is marked according to the port of the mark of the cluster carried in the acquisition request of Hadoop service page and service type
Know, Hadoop service page is obtained from corresponding cluster；
102, the URL in Hadoop service page is rewritten as being able to carry out the URL of outside access；
103, the Hadoop service page after rewriteeing URL is sent to the client of user by headend equipment.
The executing subject of the access method of the service page of the present embodiment is proxy server.The agency service of the present embodiment
The front end (Front End) of website is arranged between equipment and group system in device.May include in the group system of the present embodiment
Multiple clusters (Cluster), the cluster in the present embodiment is specially Hadoop cluster.
Since the Hadoop service page of Hadoop cluster is the state and log information that user grasps operation operation, institute
It needs to access the Hadoop service page in actual operation with user.The access method of the service page of the present embodiment is used for
Hadoop service page is provided for user.For example, the Hadoop service page in the present embodiment is specifically as follows Yarn management page
Face or Hue administration page.
In the present embodiment, the acquisition request of the Hadoop service page for the user that headend equipment is sent is specifically as follows use
Family is sent to headend equipment by used client.It is taken in the acquisition request of Hadoop service page in the present embodiment
The mark of cluster where the band Hadoop service page to be accessed and the port-mark of service type；Such as the mark tool of cluster
Body can be general exclusive identification code (the Universally Unique Identifier of the cluster；UUID).Service type
Port-mark can be the port numbers of the service type.The acquisition request of the Hadoop service page of the present embodiment is specifically as follows
One obtains uniform resource locator (the Uniform Resoure Locator of the Hadoop service page；URL).It is following to use
The acquisition request of one Hadoop service page at family is following URL:
https://bmr.bce.baidu.com/476308c-5d5b-11e6-83c4-00e0ec261caa/8088/
cluster；
Wherein, bmr.bce.baidu.com is used for location proxy server, after headend equipment receives the request, solution
The URL is analysed, it, in this way can be by the Hadoop according to the IP address of the proxy server inside bmr.bce.baidu.com parsing
The acquisition request of service page is transmitted to proxy server, so that proxy server gets following URL sections therein:
f476308c-5d5b-11e6-83c4-00e0ec261caa/8088/Cluster。
Wherein 476308c-5d5b-11e6-83c4-00e0ec261caa is the UUID of cluster, and 8088 be service type
Port numbers；Cluster is the mark of cluster.
In the present embodiment, proxy server, which is equal to, to be arranged inside website, can be with any service in any one cluster
Device node is communicated, regardless of the server node is ordinary node or Master node.Therefore, in the present embodiment, agency
The mark for the cluster that server can also carry in the acquisition request according to Hadoop service page and the port mark of service type
Know, communicated with any server node in corresponding cluster, Hadoop service is obtained from the server node of cluster
The page.
Specifically, the step 101 of the present embodiment is " according to the mark of the cluster carried in the acquisition request of Hadoop service page
Know the port-mark with service type, Hadoop service page obtained from corresponding cluster ", it can specifically include following step
It is rapid:
(a1) according to the mark of cluster, the address of cluster is obtained from Cluster Database；
(a2) according to the port-mark of the address of cluster and service type, to corresponding collection pocket transmission Hadoop service page
Acquisition request；
(a3) the Hadoop service page that cluster is returned according to the acquisition request of the Hadoop service page is received.
In the present embodiment, company-data lab setting in the cluster, is stored with all of each cluster in the Cluster Database
Information, such as it is stored with the corresponding relationship of the mark of each cluster and the address of cluster, as the mark of cluster is specifically as follows
The address of the UUID of cluster, cluster are specifically as follows the IP address of cluster.Cluster is specifically can store in Cluster Database
UUID and cluster IP address between corresponding relationship.In this way, proxy server can be according to the UUID of cluster, from cluster number
According to the IP address for obtaining the cluster in library.Then according to the port-mark of the IP address of the cluster and service type, to corresponding
Server node in cluster sends the acquisition request of Hadoop service page.Server node in the cluster is according to this
The acquisition request of Hadoop service page obtains corresponding Hadoop service page, and returning to the proxy server should
Hadoop service page.
It is the Hadoop service page inside website since proxy server receives the Hadoop service page that cluster returns,
The URL of the Hadoop service page is specially internal address, due to the external user that user is the website, if directly will collection
The Hadoop service page that group returns is sent to user, and user also can not directly access the URL of the Hadoop service page.Cause
It needs for the URL in Hadoop service page to be rewritten as in this present embodiment to be able to carry out the URL of outside access；And pass through front end
Equipment sends the Hadoop service page after rewriteeing URL to the client of user.The finally obtained Hadoop service of user in this way
The page is only accessible significant service page.
The access method of the service page of the present embodiment passes through the user's that is sent by proxy server receiving front-end equipment
The acquisition request of Hadoop service page；According to the mark and service of the cluster carried in the acquisition request of Hadoop service page
The port-mark of type obtains Hadoop service page from corresponding cluster；URL in Hadoop service page is rewritten as
It is able to carry out the URL of outside access；The Hadoop service page after rewriteeing URL is sent to the client of user by headend equipment
Face.Using the technical solution of the present embodiment, user can obtain Hadoop service page by headend equipment and proxy server,
Compared with the prior art is by way of establishing SSH Tunnel and accessing Hadoop service page, do not need user have it is certain
Technical foundation saves configuration of the user to SSH Tunnel process is established, and greatly reduces access Hadoop service page
Complexity.And the technical solution of the present embodiment, it is directly logged onto cluster internal with existing user, passes through textual form
Browser Lynx access Hadoop service page is compared, and the Hadoop service page of user's access can be with exhibiting pictures, Er Qieke
Operability is also stronger.
Still optionally further, in " the Hadoop service for the user that receiving front-end equipment is sent of the step 100 of above-described embodiment
After the acquisition request of the page ", step 101 " according to the mark of the cluster carried in the acquisition request of Hadoop service page and
It can also include the following: basis before the port-mark of service type, from acquisition Hadoop service page in corresponding cluster "
The access of cluster limits, and authenticates to the identity of user；And determine that user identity authentication passes through.
Have public network access ability since Hadoop cluster internal has a server node, directly opens the server
The serve port user of node can access, but Hadoop primary service page, such as Yarn administration page, not mention
For user authentication function, if directly open, malicious user can steal user job information by modes such as IP exhaustions,
There can be very big security risk in this way, so in the prior art, the Hadoop service page of the Hadoop cluster inside VPC is logical
It often cannot directly be accessed by browser in user client, cluster internal can only be logged on to by user or is being locallyd create
The mode of SSH Tunnel accesses.In order to increase the safety of Hadoop service page, the technical solution of the present embodiment can be with
The access of cluster limits, and authenticates provided with the identity to user, to increase the safety of Hadoop service page.Such as generation
Reason server receive headend equipment transmission user Hadoop service page acquisition request after, proxy server to
During cluster requests corresponding Hadoop service page, it is found that the cluster is provided with access limitation, need to request
The identity of the user of Hadoop service page authenticates, and does not otherwise provide Hadoop service page, can only be when to the user's
Authentication passes through, and just can provide Hadoop service page to the user.User is in the username and password of cluster can be with
Cluster internal registration is directly logged in pass through before user.
Still optionally further, " being limited according to the access of cluster, to the identity of user in the technical solution of above-described embodiment
Authenticated ", it can specifically include following steps:
(b1) it is limited according to the access of cluster, identity request information is sent to the client of user by headend equipment；
(b2) username and password of user is received by headend equipment；
(b3) according to the mark of cluster, the subscriber identity information of cluster is obtained from Cluster Database；
(b4) user of user and password are authenticated according to the subscriber identity information of cluster.
Limitation is accessed when proxy server determines that the cluster has, identity is sent to the client of user by headend equipment
Solicited message；Such as return to user can be a webpage.For example, Fig. 2 is a kind of agency's clothes provided in an embodiment of the present invention
Business device returns to the identity request page of user.As shown in Fig. 2, the page shows that proxy server passes through headend equipment to user
The identity request information that sends of client, i.e. the input frame of username and password.User is used by inputting in the input frame
Then name in an account book and password are clicked and are determined, the username and password of user is just sent to proxy server by headend equipment.This
The Cluster Database of embodiment is used to store the subscriber identity information of each cluster, for example, each cluster all users user name
With corresponding password.
After proxy server receives the username and password of the user of headend equipment transmission, such as according to the mark of cluster
The UUID of cluster obtains the identity information of all users of the cluster from Cluster Database, then according to the cluster of acquisition
The identity information of all users verify the username and password of the user.Judge the identity information of all users of the cluster
In whether include the user name and corresponding password, if do not have in all subscriber identity informations of cluster the user name or should
The corresponding password of user name and the password that user inputs are inconsistent, then do not pass through to the subscriber authentication.Only when cluster
It include the user name in all subscriber identity informations, and the corresponding password of the user name is consistent with the password that user inputs,
The subscriber authentication is passed through.
It can be seen from the above, the proxy server of the present embodiment uses HTTPS+BA (Basic Authentication；Substantially
Authentication) mode guarantee only by certification and there is user's request of operating right can just be forwarded to pair cluster
The cluster answered, the username and password that the username and password of certification uses cluster server example to log in, services domain name and card
Book is configured in front end (FrontEnd；FE) in equipment.
Proxy server cannot be directly returned to user browser after obtaining Hadoop service page from purpose cluster,
It needs to parse Hadoop service page, will wherein all URL handle, so that treated Hadoop service page
In URL user be able to access that.Specifically, in the technical solution of above-described embodiment, step 102 " will be in Hadoop service page
URL be rewritten as being able to carry out the URL " of outside access, can specifically include following several situations:
The first situation, the Content-Type of Hadoop service page include JSON character string；Can specifically include as
Lower step:
(c1) judge whether the Content-Type of Hadoop service page includes JSON character string；If including executing step
Suddenly (c2)；If not including, terminate；
(c2) whether judge in Hadoop service page including the URL to be rewritten in predefined list；If including executing
Step (c3)；If not including, terminate；
(c3) by the Host of the URL to be rewritten of Hadoop service page be rewritten as the external domain name of proxy server, to
Plus the port-mark of the mark of cluster and service type in the Path of the URL of rewriting.
The principle that URL in Hadoop service page is rewritten, is that the Host of all URL will be replaced with proxy server
External domain name, will be plus the UUID of mark cluster and the port of service type in Path.It is as described in Table 1 a kind of heavy
Write example.
Table 1
As shown in table 1, the present embodiment, can be by http when doing the URL rewriting in Hadoop service page: //
8.8.8.8:8888/Cluster https can be replaced by: //bmr.bce.baidu.com/f476308c-5d5b-11e6-
83c4-00e0ec261caa/8888/Cluster；The browser of user terminal can continue the URL after access is rewritten in this way.Agency
Server will receive request, and find cluster address according to f476308c-5d5b-11e6-83c4-00e0ec261caa
8.8.8.8, then the destination server node of cluster is forwarded requests to.
Proxy server need to Hadoop service page parse obtain rewriting in need URL, according to the page
The difference of Content Type includes JSON character string in the present embodiment in different ways with page Content-Type
For.
Specifically, judge whether the Content-Type of Hadoop service page includes JSON character string；If including；For
The JSON page can be predefined to contain in a predefined list such as preDefinedList, this preDefinedList and be wanted
The prefix of the URL of rewriting, since proxy server is mainly the relevant service page of Hadoop acted on behalf of, so this
PreDefinedList can be enumerated, and so directly be written over the field string in preDefinedList list i.e.
Can, the principle specifically rewritten is that the Host of the URL to be rewritten of Hadoop service page is rewritten as to proxy server externally
Domain name, URL to be rewritten Path in plus cluster mark and service type port-mark.
Second situation, the Content-Type of Hadoop service page include JavaScript or CSS；It specifically can be with
Include the following steps:
(d1) judge whether the Content-Type of Hadoop service page includes JavaScript or CSS；If including,
It executes step (d2)；If not including, terminate；
(d2) after obtaining the URL rewriting in Hadoop service page wait rewrite by the way of regular expression matching
URL expression formula；
(d3) by the position Host of the external domain name write-in URL expression formula of proxy server, in the Path of URL expression formula
In addition the mark of cluster and the port-mark of service type.
Unlike the first above-mentioned situation, in the second situation, with the Content- of Hadoop service page
Type is comprising for JavaScript or CSS.Specifically, judge Hadoop service page Content-Type whether include
JavaScript or CSS；If the URL in JavaScript type page is usually fixed including JavaScript or CSS
The code form of mode, the mode that regular expression matching can be used at this time are handled.Such as format " url s* (s*
(?: [" '] (? P<link>[^ " '] *) [" '] | (? P<link>S+)) " will be matched to code URL (" http: //
8.8.8.8:8888/Cluster "), and then available wherein URL to be rewritten；Then according to that proxy server is external
Domain name be written URL expression formula the position Host, in the Path of URL expression formula plus cluster mark and service type end
Mouth mark, is written over URL.That is the URL of each type is expressed to can be matched to a kind of regular expression
URL expression formula.Then according to this expression formula, URL wherein to be rewritten is rewritten according to the rewriting principle of URL.
Simultaneously in order to avoid all Hadoop service pages will carry out traversal processing to all regular expressions, in reality
Regular expression can be done according to the keyword of demand file and be classified on now, different files is only needed to be traversed in the page and can be used
The regular expression list arrived；
The third situation, the processing of html page；It can specifically include following steps:
(e1) judge whether Hadoop service page is html page；If so, executing step (e2)；If not including, terminate；
(e2) obtain Hadoop service page in include URL to be rewritten label；
(e3) Host of the URL to be rewritten in label is rewritten as the external domain name of proxy server, URL to be rewritten
Path in plus cluster mark and service type port-mark.
If the Content Type in Hadoop service page contains the keyword in excludedList,
Keyword in excludedList has csv, image, stream, xml, xsl etc., and the page of these types does not have to process.
