Along with the application of group system is more and more extensive, the performance of cluster more and more becomes the problem that user is concerned about very much.As the iozone of one of the important tool of test cluster disk/file system performance, usage frequency is more and more higher, the use especially under Linux platform.
Iozone is the benchmark instrument of a file system, can test the readwrite performance of the file system in different operating system.Read can be tested, the hard disk performance under the different modes such as write, re-read, re-write.The default use rsh of iozone cluster test, in order to improve security of system, reduces the complexity of cluster configuration simultaneously, the invention provides the collocation method that a kind of iozone cluster connected by ssh is tested.
Summary of the invention
The present invention is directed to the weak point that prior art exists, propose a kind of method configuring the test of iozone cluster.
A kind of method configuring the test of iozone cluster of the present invention, the technical scheme solving the problems of the technologies described above employing is as follows: the mode that the method is connected by ssh realizes, and improves the security of group system; Adopt between the basic configuration-clustered node of multiplexing cluster and configure the method for ssh without password login, alleviate cluster configuration complexity, realize the test of iozone cluster; Mainly comprise following three steps: 1) the internodal ssh of allocation cluster is without password login; 2) by amendment environmental variance, the configuration that ssh is used as default rsh is realized; 3) the cluster test node file of iozone is set.
Preferably, the internodal ssh of allocation cluster, without password login, refers to that the main frame of cluster and other machines can log in without password by ssh mutually.
Preferably, by amendment environmental variance, realize the configuration that ssh is used as default rsh, the mode by revising temporarily: under shell, perform successively: export RSH=ssh; Export rsh=ssh.
Preferably, by amendment environmental variance, the configuration that ssh is used as default rsh is realized, the mode by forever revising: in environmental variance file ~/.bashrc, add: export RSH=ssh; Export rsh=ssh;
Then perform source. bashrc under shell, variable is come into force.
Preferably, the cluster test node file of Iozone is set, comprises the cluster IP address (machine name) that Iozone is set, the file system name of testing, Iozone path.
Preferably, by each test node is copied multirow, open multiple process at each test node and test.
The beneficial effect that the method for a kind of iozone of configuration cluster test of the present invention compared with prior art has is: the iozone cluster test that this method is connected by ssh, improves the security of group system; And without the characteristic of password login between the multiplexing well basic configuration-clustered node of cluster of the method, alleviate cluster configuration complexity, improve work efficiency.
Accompanying drawing explanation
Accompanying drawing 1 is the process flow diagram of the method for configuration iozone cluster test.
Embodiment
For making the object, technical solutions and advantages of the present invention clearly understand, below in conjunction with specific embodiment, and with reference to accompanying drawing, a kind of method configuring the test of iozone cluster of the present invention is further described.
A kind of method configuring the test of iozone cluster of the present invention, propose the collocation method of the iozone cluster test that a kind of ssh connects, when iozone cluster is tested, the mode connected by ssh is realized, and improves the security of group system; Adopt between the basic configuration-clustered node of multiplexing cluster and configure the method for ssh without password login, alleviate cluster configuration complexity, realize the test of iozone cluster.
Embodiment 1:
A kind of method configuring the test of iozone cluster described in the present embodiment, on the one hand, adopt the encrypted transmission of ssh, the mechanism features of key authentication can improve the security of group system; On the other hand at present ssh has become the basic configuration of Linux group system without password login, and the test of iozone cluster can this characteristic of multiplexing Linux group system, and then alleviates the complexity of configuration, improves work efficiency.
The method of this configuration iozone cluster test, as shown in Figure 1, mainly comprises following three steps: 1) the internodal ssh of allocation cluster is without password login; 2) by amendment environmental variance, the configuration that ssh is used as default rsh is realized; 3) the cluster test node file of iozone is set.
1) the internodal ssh of allocation cluster is without password login, specifically comprises: should cluster main frame can ssh without the other machines in password login cluster, and other machines also want can ssh without password login main frame.The configuration of this step is carried out in the basic configuration of cluster in early stage, direct multiplexing early stage cluster configuration.
2) by amendment environmental variance, realize the configuration that ssh is used as default rsh: default the uses rsh of the cluster of iozone test, and at present rsh substantially replace by ssh, therefore needing to configure ssh is used as default rsh, realized by amendment environmental variance, have two kinds of modes:
(1) mode of interim amendment: under shell, perform successively: export RSH=ssh; Export rsh=ssh;
(2) mode of permanent amendment: in environmental variance file ~/.bashrc, add: export RSH=ssh; Export rsh=ssh;
Then perform source. bashrc under shell, variable is come into force.
3) the cluster test node file of Iozone is set, comprises IP address (machine name), the file system name of test, Iozone path, such as: nodeA/clustere/root/iozone3_413/src/current/iozone
nodeB /clusterb /root/iozone3_413/src/current/iozone
If want that opening multiple process at each test node tests, and can copy multirow each test node.
