Detailed Description

In order to make the objects, technical solutions and advantages of the embodiments of the present invention more apparent, the embodiments of the present invention are further described in detail below with reference to the accompanying drawings. The exemplary embodiments and descriptions of the present invention are provided to explain the present invention, but not to limit the present invention.

The embodiment of the invention provides a cluster system deployment method, which is used for solving the technical problem that serious accidents may occur to an online database due to the fact that the existing MySQL high-availability cluster deployment operation is complicated and errors are easy to occur.

Fig. 1 is a flowchart of a method for deploying a cluster system in an embodiment of the present invention, as shown in fig. 1, the method includes the following steps:

s101, importing a software program package of the cluster system to be deployed.

It should be noted that, in the cluster system, a plurality of servers are collected to provide a certain service, and the client appears as if there is only one server. The cluster system to be deployed in the embodiment of the present invention may be, but is not limited to, a MySQL high-availability architecture cluster system. The software package imported in S101 includes all software installation packages and dependency packages required for deploying the cluster system to be deployed.

Optionally, when the cluster system to be deployed is a MySQL high-availability architecture cluster system, the software package at least includes: MySQL configuration files, MySQL installation packages, MHA configuration files, MHA dependency packages and MHA installation packages.

Further, in order to simplify the deployment operation of the cluster system and implement one-key installation deployment, in an embodiment, the software package may further include a one-key installation script, where the one-key installation script is used to install the MySQL installation package according to the MySQL configuration file, and install the MHA dependency package and the MHA installation package according to the MHA configuration file.

S102, acquiring parameter information of each server of the cluster system to be deployed.

In one embodiment, in order to implement optimal deployment of the cluster system, the one-key installation script is further used for parameter information of each server, determining a MySQL server and an MHA server of the cluster system to be deployed, and setting configuration parameters of the MySQL server and the MHA server.

Since the CPU utilization and the memory utilization of the servers may affect the performance of the cluster system, in one implementation, the parameter information of each server acquired in the above step S102 at least includes: the CPU utilization rate and the memory utilization rate of each server; the configuration parameters of the MySQL server and the MHA server set by the one-key installation script at least comprise: reading data thread number, writing data thread number, refreshing data thread number and caching upper limit value.

S103, logging in each server according to the parameter information of each server, installing a software program package of the cluster system to be deployed, and completing the deployment of the cluster system to be deployed.

It should be noted that the foregoing S101 to S103 may be applied to one central control server, that is, the software package of the cluster system to be deployed is imported into one central control server, and the central control server logs in to another server to perform deployment of the cluster system.

In one embodiment, the central control server can log in to each server in an SSH password-free login mode. When the central control server deploys the cluster system, the deployment of the cluster system to be deployed can be rapidly completed in a copying mode.

As can be seen from the above, in the cluster system deployment method provided in the embodiment of the present invention, the software package of the cluster system to be deployed is imported into the central control server, and the central control server logs in each server according to the parameter information of each server, installs the software package of the cluster system to be deployed, completes the deployment of the cluster system to be deployed, and is not required to be connected to the internet, thereby achieving the rapid deployment of the cluster system, reducing the difficulty of the cluster deployment, and improving the efficiency of the cluster deployment.

Since a certain server may be down in the cluster system frequently, in an embodiment, the software package imported in S01 may further include: and the switching script is used for switching the service provided by the downtime server to other normal servers under the condition that the downtime server exists in the cluster.

When the cluster system deployment method provided in the embodiment of the present invention is applied to a MySQL high-availability architecture cluster system, the deployment of the cluster system to be deployed may be completed through the following steps: deploying the MHA management node on a single server; and the system is deployed on MHA data nodes and MySQL master and slave databases on other servers.

It should be noted that mha (master High availability) is a relatively mature solution in terms of MySQL High availability at present, and is an excellent set of High-availability software for failover and master-slave promotion in the MySQL High-availability environment. In the MySQL fault switching process, the MHA can automatically complete the fault switching operation of the database within 0-30 seconds, and in the fault switching process, the MHA can ensure the consistency of data to the maximum extent so as to achieve high availability in the true sense.

The software consists of two parts: MHA Manager and MHA Node. Node runs on each MySQL server, that is, whether MySQL master server or MySQL slave server, Node is installed, and Manager usually runs on a separate server, but if hardware resources are tight, one MySQL slave server can also play the role of Manager. The MHA Manager will periodically detect the Master node in the cluster, when the Master fails, it can automatically promote the latest data Slave to the new Master, and then redirect all other Slave to the new Master. The entire failover process is completely transparent to the application.

In an embodiment, as shown in fig. 2, after logging in each server according to parameter information of each server, installing a software package of a cluster system to be deployed, and completing deployment of the cluster system to be deployed, the cluster system deployment method provided in the embodiment of the present invention may further include the following steps:

s104, receiving a database access request from a client;

and S105, connecting the databases of the deployed cluster systems through the VIP addresses according to the database access request.

Fig. 3 is a schematic diagram of a MySQL high-availability architecture provided in an embodiment of the present invention, as shown in fig. 3, including: MHA management node, a master-slave replication group 1, a master-slave replication group 2 and a master-slave replication group 3.

The MHA management node is usually deployed on an independent machine or directly on one of the MySQL Slave. Managing a plurality of Master/Slave clusters or a cluster, wherein each Master/Slave cluster is called application; the main roles of MHA manager are: master automatic switching and failover command operation. 2. Other maintenance scripts run, such as manual switch Master, Master/Slave status checks. Is the brain and command of the MHA high-availability cluster.

Master and Slave in the Master-Slave copy group 1, the Master-Slave copy group 2 and the Master-Slave copy group 3 refer to Master and Slave libraries of MySQL, and a MySQL binlog copy mode is adopted. Meanwhile, node applications of the MHA are also deployed on the master libraries and the slave libraries. The MHA data nodes are operated on each MySQL server, and accelerate the fault transfer by monitoring scripts with the functions of analyzing and cleaning logs. The main functions are as follows: a. binding log data of the solid execution host node; b. comparing the relay log files of the slave nodes; c. the relay log is deleted regularly without stopping the SQL thread of the slave node. The MHA data nodes are carriers and executors of the MHA high-availability cluster.

The working principle of MHA is as follows:

saving binary log events (binlog events) from a Master that crashes the downtime;

identifying the Slave containing the latest update;

thirdly, applying the relay log (relay log) of the difference to other Slave;

(iv) applying binary log events (binlog events) saved from Master;

fifthly, one Slave is promoted to be a new Master;

and sixthly, connecting other Slave to a new Master for copying.

Fig. 4 is a flowchart of an application of MySQL high availability architecture provided in the embodiment of the present invention, and as shown in fig. 4, the application server may be a Web application server or an APP application server. When a user makes requests from a Web application or APP application, the application server will accept these requests for the first time.

And when the application server receives the request, processing the information, and if the request of the back-end MySQL needs to be accessed, connecting the database through the VIP. The VIP layer has the effect that when the rear-end MySQL main library is down switched, the externally exposed IP address is not changed, and the application program does not need to switch the MySQL main library and change the IP address.

The MySQL master-slave replication group shown in fig. 4 is a cluster built up by MySQL master-slave replication. By default, the VIP is bound to the Master node, and the Master is requested to be connected by default. Meanwhile, MHA node applications are deployed in both master and slave libraries in the cluster.

The MHA manager shown in fig. 4 is a node outside the MySQL master slave replication group, and is deployed independently. The deployment has the advantages that the deployment is not influenced by the availability of the copy group, and one manager node can be used for controlling a plurality of MySQL master-slave copy groups. When the disadvantage is that there is only one set of MySQL master-slave copies, this deployment wastes one machine. At this time, it is better to deploy one of the Slave together.

As shown in fig. 5, a MySQL high-availability architecture deployment flow provided in the embodiment of the present invention is shown, and as can be seen from fig. 5, the cluster system deployment method provided in the embodiment of the present invention can implement one-key deployment of a cluster.

The central server shown in fig. 5 can log on to all other servers in an SSH password-free login manner. And the central control server stores all installation packages and dependency packages which are needed to be used by the MySQL high-availability cluster deployment. The method comprises the following steps: the system comprises a one-key installation script, a MySQL configuration file, a MySQL installation package, an MHA configuration file, an MHA dependency package, an MHA installation package, a switching script and the like.

The MySQL installation package is an installation package which is re-tar packaged after directory structure adjustment, redundant module filtration and adjustment by combining the content of the configuration file according to a binary installation package provided by a MySQL official network. The method is mainly used for installing MySQL; MHA dependent packets mainly include createrepo rpm (rpm packet for making local image), perl rpm (installation packet of perl language environment required by MHA), telnet rpm (for testing port connectivity). The MHA installation package mainly comprises two installation packages of MHA4MySQL-manager-0.58-0.el7. centros. nanoch. rpm and MHA4MySQL-node-0.58-0.el7. centros. nanoch. rpm, and is mainly used for installing MHA.

The one-key installation script can determine the MySQL server and the MHA server which need to be deployed according to the transmitted parameters; determining a master-slave relationship according to the incoming parameters; setting the optimal configuration of the MySQL configuration parameters according to the parameters; the MHA parameter configuration is adjusted according to the incoming parameters.

The required incoming parameters are:

-c 1: the number of cores that allow MySQL to use cpu at most is specified.

-m 4: specifying the size that allows MySQL to use the content at most. The unit G.

-p/data/: the path of the MySQL installation is specified.

-Mip: the master library ip is specified.

-Sip 1; ip 2: the slave library ip is specified.

-Uroot: mha manage accounts for MySQL instances.

-Ppasswd: mha password to MySQL instance.

-t mha: the parameters can be selected from mha, ms and alone. The start mha selects that a-v parameter must be added. ms is the master-slave relationship. And the Alone is a single machine.

-vip: the designation vip, mha will be used. T parameter selection mha before the parameter becomes valid.

The MySQL configuration parameters and MHA configuration parameters mentioned above have most of the parameters set to the optimal configuration, which is placed in the installation package. The optimal configuration of a small part of parameters is related to the resource configuration of the server, so that in the parameters transmitted by the one-key installation script, the cpu and the memory index are particularly important, and the optimal configuration can be carried out according to the index by the nested optimization scheme in the script. The method comprises the read-write thread number (related to the cpu number) of MySQL, the thread number (related to the cpu) of MySQL refreshing log and the preset cache upper limit (related to the memory) of MySQL.

For example, when a cluster deployment worker deploys a set of MySQL clusters, after determining the base version, the cluster deployment worker needs to confirm and grasp the information such as: MySQL configuration parameters, high available architecture solutions, how to deploy MySQL high available architecture, etc. The deployment is strictly limited in time, for example, the deployment needs to be completed in half a day, at the moment, the knowledge system of cluster deployment workers is limited, the skills are not completely mastered, and the online teaching documents are difficult to digest in half a day. The company or the first party is urging to be urgent.

By the cluster system deployment method provided by the embodiment of the invention, cluster deployment workers can determine all problems of cluster deployment within a few minutes by simply transmitting parameters, inputting parameter information of the server and clicking to enter, so that tasks can be quickly completed, and the deployment can be completed in an optimal mode.

Based on the same invention concept, the embodiment of the invention also provides a cluster system deployment device, which is used for solving the technical problem that the existing MySQL high-availability cluster deployment operation is complicated and is easy to make mistakes, so that serious accidents may occur to the online database. As described in the examples below. Because the principle of solving the problems of the device is similar to the cluster system deployment method, the implementation of the device can be referred to the implementation of the cluster system deployment method, and repeated details are not repeated.
