1. You can’t deploy service on IP 127.0.0.1 for the following reasons:

  1. each service has at least one obj to serve foreign clients;

  2. each service has a obj for administration, it binds to ip 127.0.0.1 and the same port which servant obj binds to.

2. Tars consists of RPC framework, basic services, web management system, etc.

The RPC framework supports C++ , Java, Go, Php, Nodejs. Each language has its related baselib, idl generate-code tools, and implementation of client’s and server’s code, all can run on linux/mac/windows.

3. The software and tools that Tars depends must be prepared before deploy Tars, see Install.md.

4. The steps of deploying Tars must follow the specified order described in Install.md

5. After executing of tars_start.sh, please execute command ps -ef|grep tars to check that the core service processes of Tars are alive, ie, tarsregistry, tarsAdminRegistry, tarsnode, tarsconfig and tarspatch.

6. The paths in which services deployed as below:

Log file path: /usr/local/app/tars/app_log/${Application}/${ServiceName}/, such as

/usr/local/app/tars/app_log/Test/HelloServer/

Executable file path: /usr/local/app/tars/tarsnode/data/${Application}.${ServiceName}/bin/, such as

/usr/local/app/tars/tarsnode/data/Test.HelloServer/bin/

Template config file path: /usr/local/app/tars/tarsnode/data/${Application}.${ServiceName}/conf/, such as

/usr/local/app/tars/tarsnode/data/Test.HelloServer/conf/

Cache file path: /usr/local/app/tars/tarsnode/data/${Application}.${ServiceName}/data/, such as

/usr/local/app/tars/tarsnode/data/Test.HelloServer/data/

7. How to check logs
