1. Install third party library packages

   (1) Download third party library packages and put it in your home folder;

   Completed version for centos

   And we recommend you download completed version.(umcompleted version need to download some lib from source, we download all thirdparty libs for you)

    tar -xzvf thirdparty_CENTOS7.tar.gz 

(3) run the shell  
    Attention: Install process will ask you to write claims_home. (claims_home means the absolute path of CLAIMS folder)

   cd thirdparty
 
   ./autotools

   ./install.sh

   enter 1

2. Initialize git and git clone CLAIMS( checkout to latest version)

    git init

    git clone [email protected]:dase/CLAIMS.git

    git checkout for_auto_test 

Maybe you need to add claims_home in ~/.bashrc file. if you forget enter claims_home in (3) step.
[click here to see recommanded config and bashrc](https://github.com/dase/CLAIMS/wiki/Configure)

   vi ~/.bashrc

   add "export CLAIMS_HOME=/usr/claims/Desktop/git/CLAIMS"
      
   source ~/.bashrc

3. Compilation and Installation

   cd $CLAIMS_HOME
   
   ./build.sh init
   
   mkdir install
    
   cd install
   
   ../configure

   make -j4    

4. Configure

   Default configure file at /CLAIMS/conf/config, please set the path for data and catalog! and do not forget change ip。 please see Configure.

   In standalone mode you just need set data directory.

     eg. data="/home/claims/Desktop/data/"  
   

   Do not forget the slash at the end of it.

     data="/home/claims/Desktop/data" is wrong example

if you want to run test, please run (Under the premise of loaded data successfully)

   cd $CLAIMS_HOME/sbin/claims-test
   
   ./run-gtest.sh

Note: ./claimsserver -h can give you help, ./client ip port


./test --ip 127.0.0.1 --port 10000 for test if you have tpc-h sf=1 data 
and load it with partition=1. please see [[DDL of SQL]].
