1上傳已編譯完的包至/data/目錄

2.解壓

3 修改gpadmin的環(huán)境變量

1. [gpadmin@DB-01 ~]$ more .bash_profile
   

2. # .bash_profile
   

3. 
   

4. # Get the aliases and functions
   

5. if [ -f ~/.bashrc ]; then
   

6.         . ~/.bashrc
   

7. fi
   

8. 
   

9. # User specific environment and startup programs
   

10. 
    

11. PATH=$PATH:$HOME/bin
    

12. 
    

13. export PATH
    

14. source /data/gpdb/greenplum_path.sh    ---bin目錄
    

15. export MASTER_DATA_DIRECTORY=/data/gpdb/gpdata2/gpmaster/gpseg-1  --數(shù)據(jù)目錄
    

16. export PGPORT=5432
    

17. export PGDATABASE=ecejdatainfo

4 修改初始化配置文件

1. [gpadmin@DB-01 conf]$  pwd
   /home/gpadmin/conf
   

2. [gpadmin@DB-01 conf]$ ll
   

3. total 16
   

4. -rw-rw-r-- 1 gpadmin gpadmin 2910 May 26 14:04 gpinitsystem_config
   

5. -rw-rw-r-- 1 gpadmin gpadmin 2703 Jul  6 20:58 gpinitsystem_config2
   

6. -rw-rw-r-- 1 gpadmin gpadmin   62 May 26 10:17 hostlist
   

7. -rw-rw-r-- 1 gpadmin gpadmin   51 May 26 10:17 seg_hosts

8. [gpadmin@DB-01 conf]$ more gpinitsystem_config2   ---修改對(duì)應(yīng)的數(shù)據(jù)目錄 /data/gpdb/gpdata2
   # FILE NAME: gpinitsystem_config
   
   
   # Configuration file needed by the gpinitsystem

2. [gpadmin@DB-01 gpdata2]$ ll
   

3. total 36
   

4. drwxrwxr-x 2 gpadmin gpadmin 4096 Jul  6 20:57 gpdatam1
