Each microservice in 0.X has a root directory that exists independently. The main advantage of this directory structure is that it is easy to distinguish microservices and facilitate individual Microservices are managed, but there are some obvious problems:</p><ol><li>The microservice catalog is too complicated and it is not convenient to switch catalog management</li><li>There is no unified startup script, which makes it more troublesome to start and stop microservices</li><li>There are a large number of duplicate service configurations, and the same configuration often needs to be modified in many places</li><li>There are a large number of repeated Lib dependencies, which increases the size of the installation package and the risk of dependency conflicts</li></ol><p>Therefore, in Linkis 1.0, we have greatly optimized and adjusted the installation directory structure, reducing the number of microservice directories, reducing the jar packages that are repeatedly dependent, and reusing configuration files and microservice management scripts as much as possible. Mainly reflected in the following aspects:</p><p>1.The bin folder is no longer provided for each microservice, and modified to be shared by all microservices.</p><blockquote><p>The Bin folder is modified to the installation directory, which is mainly used to install Linkis 1.0 and check the environment status. The new sbin directory provides one-click start and stop for Linkis, and provides independent start and stop for all microservices by changing parameters.</p></blockquote><p>2.No longer provide a separate conf directory for each microservice, and modify it to be shared by all microservices.</p><blockquote><p>The Conf folder contains two aspects of content. On the one hand, it is the configuration information shared by all microservices. This type of configuration information contains information that users can customize configuration according to their own environment; on the other hand, it is the special characteristics of each microservice. Configuration, under normal circumstances, users do not need to change by themselves.</p></blockquote><p>3.The lib folder is no longer provided for each microservice, and modified to be shared by all microservices</p><blockquote><p>The Lib folder also contains two aspects of content, on the one hand, the common dependencies required by all microservices; on the other hand, the special dependencies required by each microservice.</p></blockquote><p>4.The log directory is no longer provided for each microservice, modified to be shared by all microservices</p><blockquote><p>The Log directory contains log files of all microservices.</p></blockquote><p>The simplified directory structure of Linkis 1.0 is as follows.</p><div class="codeBlockContainer_J+bg"><div

sponsored by the Apache Incubator. Incubation is required of all newly accepted projects until a further review indicates that the infrastructure, communications, and decision making process have stabilized in a manner consistent with other successful ASF projects. While incubation status is not necessarily a reflection of the completeness or stability of the code, it does indicate that the project has yet to be fully endorsed by the ASF.</p><p></p> |
