Embodiment
Below in conjunction with specific embodiment, the present invention is described in detail.Following examples will contribute to those skilled in the art and understand the present invention further, but not limit the present invention in any form.It should be pointed out that to those skilled in the art, without departing from the inventive concept of the premise, some distortion and improvement can also be made.These all belong to protection scope of the present invention.
First illustratively in cluster, how individual node carries out application program update.
Utilize an application program source to safeguard up-to-date application program, when needs upgrade cluster, only need to upgrade the program in application program source or configuration, the more new script so on clustered node will automatically detect and changes and automatically upgrade.
Automatically more the processing logic of new script is as follows:
1, latest edition file is downloaded from application program source server assigned address;
2, compare city edition presents and latest edition file, check whether it is latest edition;
3, if not latest edition, first delete local application file, then copy application program source server application file version to this locality.
If but under cluster environment, all nodes are upgraded, then simultaneously cluster service at no point in the update process can be made to be in down state, can not to accomplish that the heat of cluster is disposed.
Accomplish that the heat of cluster is disposed, can be realized by each node upgraded successively in cluster, can accomplish that the application of any moment cluster is all in upstate like this.
These needs realize at certain station server (can put together with application program source server) of separate cluster node the script that upgrades clustered node successively, and this script specific implementation step is as follows:
1, the list of all nodes in cluster is obtained, by the node in step 2 traversal of lists;
2, obtain node address, long-range be connected to this node and perform automatically more new script carry out version updating;
3, step 2 is repeated, until all nodes all upgrade complete in cluster.
By above method, the renewal of all nodes in cluster can be realized, and make this cluster in renewal process be in upstate all always.But at no point in the update process, the simultaneous situation of new early version can be there is, the service state that so this cluster will be made to provide is inconsistent, because reverse proxy service may be forwarded to request the node at redaction place for a moment, is forwarded to again the node at legacy version place for a moment.
Upgrade each node in cluster successively, but when have in cluster redaction node can with after, reverse proxy is understood and new request is automatically forwarded on new node.In this way, service is in upstate to profit always, and only has a version simultaneously and be that latest edition can be used.
These needs safeguard new node pond and old node pool on Reverse Proxy, and it is as follows that this script performs step:
1, the latest edition file in down load application program source;
2, all node listings of cluster are obtained, according to step 3,4 traversal of lists;
3, obtain the version file on node, and compare with latest edition file;
If the version file of 4 nodes is identical with latest edition file, then this node is added in new node pond, otherwise add in old node pool point pond;
5, step 3,4 is repeated, until traveled through all nodes in cluster.
Reverse Proxy, when carrying out request forward, can judge according to the number in new node pond, when new node pool count is 0, then can be old node pool point pond for the node pool forwarded; Otherwise, can be new node pond Dian Chi for the node pool forwarded.This ensures that there, once there be a node updates to complete, then new request just will all be forwarded on the application server of redaction.
Above specific embodiments of the invention are described.It is to be appreciated that the present invention is not limited to above-mentioned particular implementation, those skilled in the art can make various distortion or amendment within the scope of the claims, and this does not affect flesh and blood of the present invention.
