Developer Guide and Troubleshooting

Uninstall Guide

1. Stop all tars processes

            /usr/local/app/tars/tars-stop.sh

       2. Delete files

           rm -rf /usr/local/app/tars

           rm -rf /usr/local/app/patchs

           rm -rf /usr/local/app/web

           rm -rf /usr/local/tars

       3. Delete crontab

           crontab -e

           **Delete this line " * * * * * /usr/local/app/tars/tarsnode/util/monitor.sh "**

Troubleshooting

1. You can’t deploy service on IP 127.0.0.1 for the following reasons:
  a)Each service has at least one obj to serve foreign clients;
  b)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. After executing of tars_start.sh, please execute command ps -ef|grep tars to check that the core service processes of Tars are alive,
  i.e., tarsregistry, tarsAdminRegistry, tarsnode, tarsconfig and tarspatch.

3. The paths in which services deployed as below:
  a)Log file path: /usr/local/app/tars/app_log/${Application}/${ServiceName}/, such as
     /usr/local/app/tars/app_log/Test/HelloServer/
  b)Executable file path: /usr/local/app/tars/tarsnode/data/${Application}.${ServiceName}/bin/, such as
     /usr/local/app/tars/tarsnode/data/Test.HelloServer/bin/
  c)Template config file path: /usr/local/app/tars/tarsnode/data/${Application}.${ServiceName}/conf/, such as
     /usr/local/app/tars/tarsnode/data/Test.HelloServer/conf/
  d)Cache file path: /usr/local/app/tars/tarsnode/data/${Application}.${ServiceName}/data/, such as
     /usr/local/app/tars/tarsnode/data/Test.HelloServer/data/

4. How to check logs
  For example, there will be a log file named Test.HelloServer.log in directory
  /usr/local/app/tars/app_log/Test/HelloServer/. If something failed, please check it.

5. tarsnode can not run java server: cannot execute java
  Please restart tarsnode after install jdk
  /usr/local/app/tars/tarsnode/util/start.sh
