When you use obd.sh to run mysqltest for test, you must use an OceanBase database deployed by using obd.sh. This topic describes how to compile the source code, use obd.sh to deploy OceanBase Database, and run mysqltest for test.
Background information
To simplify operations, we have encapsulated some commands of OceanBase Deployer (OBD) into the obd.sh script. The script is stored in the oceanbase/tools/deploy directory of the OceanBase source code. In this example, mysqltest calls the obd test mysqltest command in OBD.
Concepts
mysqltest runs entry tests for OceanBase Database. It uses a written test case file as the input and compares the database output against the expected output. mysqltest cases are all located in the oceanbase/tools/deploy/mysql_test directory of the OceanBase source code.
A case is the minimum execution unit of mysqltest, and contains at least one test file and one result file. A suite is a collection of cases of the same type.
mysqltest tests can be classified into different modes. Each mode consists of different nodes.
Note
For more information about the parameters in mysqltest, see Appendix.
c mode: Connect to the server node where the primary zone resides and run mysqltest. If the OceanBase cluster is deployed by using the
distributed.yamlconfiguration file, connect to the cluster based on the settings in theserver1section in the configuration file to run the test../obd.sh mysqltest -n <name> --suite acs --test-server=server1Slave mode: Connect to the server node where a non-primary zone resides to run mysqltest. If the OceanBase cluster is deployed by using the
distributed.yamlconfiguration file, connect to the cluster based on the settings in theserver2section in the configuration file to run the test../obd.sh mysqltest -n <name> --suite acs --test-server=server2Proxy mode: Use OceanBase Database Proxy (ODP) to connect to an OceanBase cluster to run mysqltest. For example, use the
distributed-with-proxy.yamlconfiguration file to deploy a cluster and run the test../obd.sh mysqltest -n <name> --all
Procedure
This topic uses an x86 CentOS Linux 7.9 server as the environment. For more information about the compilation and deployment process, see GitHub repository.
Step 1: Compile the source code of OceanBase Database
Download the source code of OceanBase Database.
[admin@obtest ~]$ git clone https://github.com/oceanbase/oceanbase.gitPrepare the dependency package based on the operating system.
[admin@obtest ~]$ sudo yum install git wget rpm* cpio make glibc-devel glibc-headers binutils m4Perform compilation.
[admin@obtest ~]$ cd oceanbase [admin@obtest oceanbase]$ bash build.sh release --init --make
Step 2: Deploy the compiled OceanBase file
Prepare the configuration file.
[admin@obtest ~]$ sudo yum install -y yum-utils [admin@obtest ~]$ sudo yum-config-manager --add-repo https://mirrors.aliyun.com/oceanbase/OceanBase.repo [admin@obtest ~]$ sudo yum install -y libtool libaio obclient [admin@obtest ~]$ cd oceanbase/tools/deploy [admin@obtest deploy]$ ./obd.sh prepareThe
obd.sh preparecommand copies the binary file from the compilation directory, such as build_release, creates an image, and then generates a default configuration file based on the current environment. If multiple compilation directories exist, the command selects the first one by default.You can use the default configuration file that is generated during the deployment. You can also download other configuration files from the GitHub repository and modify them as needed. You must select a configuration file based on the test mode of mysqltest.
Note
For more information about test modes of mysqltest, see Concepts.
You can use any configuration file to run a mysqltest test in c mode.
To run a mysqltest test in slave mode, you must use the
distributed.yamlordistributed-with-proxy.yamlfile to deploy a two-node cluster.To run a mysqltest test in proxy mode, you must use the
distributed-with-proxy.yamlfile to deploy an OceanBase cluster and deploy ODP in the OceanBase cluster.
(Optional) Modify the configuration file.
To modify the port and directory information in a configuration file, run the following command:
[admin@obtest deploy]$ vim distributed-with-proxy.yamlThe following table describes the key parameters.
Parameter Required Description servers Yes Specify each server in the format of - name: server identifier (line feed) ip: server IP address. You can specify multiple servers. The server identifiers must be unique.
You can specify unique server IP addresses in the format of- <ip> (line feed)- <ip>, where- <ip>is equivalent to- name: server IP address (line feed) ip: server IP address.mysql_port Yes The port number for the SQL service protocol. rpc_port Yes The port number for remote access, which is the RPC communication port between the observer process and other node processes. home_path Yes The installation path of the component. production_mode Yes Specifies whether to enable the production mode. If the production mode is enabled, mysqltest checks whether the server resources meet the production environment requirements. We recommend that you disable this mode for a test scenario. Otherwise, the deployment may fail. devname No The network interface card (NIC) corresponding to the IP address specified in servers. You can view the mapping between IP addresses and NICs by using theip addrcommand.listen_port Yes The listening port of ODP. prometheus_listen_port Yes The Prometheus service port of ODP. Deploy OceanBase Database.
[admin@obtest deploy]$ ./obd.sh deploy -c distributed-with-proxy.yaml -n testHere,
-cspecifies the path of the configuration file for deployment. In this example, thedistributed-with-proxy.yamlfile is used.-nspecifies the name of the cluster to be deployed. In this example,testis used.
Step 3: Run the mysqltest test
You can select a full test or specify the cases or suites for the test.
Run the following commands to perform a full test, namely to run all suites in the
mysql_test/test_suitedirectory:[admin@obtest ~]$ cd oceanbase/tools/deploy [admin@obtest deploy]$ ./obd.sh mysqltest -n test --allRun the following commands to perform a test by specifying the test cases, for example, test cases in
mysql_test/test_suite/alter/t/alter_log_archive_option.test:[admin@obtest ~]$ cd oceanbase/tools/deploy [admin@obtest deploy]$ ./obd.sh mysqltest -n test --test-dir ./mysql_test/test_suite/alter/t --result-dir ./mysql_test/test_suite/alter/r --test-set alter_log_archive_optionRun the following commands to perform a test by specifying the test suites, for example, suites in the
mysql_test/test_suitedirectory:[admin@obtest ~]$ cd oceanbase/tools/deploy [admin@obtest deploy]$ ./obd.sh mysqltest -n test --suite acs
Appendix
When you run a mysqltest test, you can configure options as required. The following table describes the options.
| Option | Required | Data type | Default value | Description |
|---|---|---|---|---|
| -n | Yes | String | Empty | The name of the cluster where the test is executed. |
| --component | No | String | Empty | The name of the component to be tested. Valid values: obproxy, obproxy-ce, oceanbase, and oceanbase-ce. If you do not specify a value, the existence of obproxy, obproxy-ce, oceanbase, and oceanbase-ce is checked sequentially. The traversal stops when a component is found, and the component is then tested. |
| --test-server | No | String | The name of the first node under the specified component. | You can set this parameter to the value of name in servers in the .yaml file. If name is not specified for the servers parameter, you can use the ip value. It must be a node under the specified component. |
