单机安装greenplum记录

1.假设单机hostname为bsa175

2.将greenplum-db-4.3.10.0-build-1-rhel5-x86_64.zip解压缩，可以得到greenplum-db-4.3.10.0-build-1-rhel5-x86_64.bin文件

3.运行./greenplum-db-4.3.10.0-build-1-rhel5-x86_64.bin，将安装路径设置为~/greenplum（视自己想安装的路径情况而定）

4.在~/greenplum中写入文件seg_hosts和hostlist，里面的内容为bsa175

5.使用gpssh-exkeys将所有机器通道打开

~/greenplum/bin/gpssh-exkeys -f ~/greenplum/hostlist

6.新建数据目录

mkdir -p ~/greenplum/gpdata/gpmaster

mkdir -p ~/greenplum/gpdata/gpdatap1

mkdir -p ~/greenplum/gpdata/gpdatap2

mkdir -p ~/greenplum/gpdata/gpdatam1

mkdir -p ~/greenplum/gpdata/gpdatam2

7.将~/greenplum/docs/cli_help/gpconfigs/gpinitsystem_config拷贝为~/greenplum/initgp_config

8.修改~/.bashrc

source ~/greenplum/greenplum_path.sh
export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/home/bsaworker/greenplum/lib
export GPHOME=/home/bsaworker/greenplum
export MASTER_DATA_DIRECTORY=/home/bsaworker/greenplum/gpdata/gpmaster/gpseg-1

然后令其生效,source ~/.bashrc

9.修改~/greenplum/initgp_config

红字为修改之处。

10.运行

~/greenplum/bin/gpseginstall -f ~/greenplum/hostlsit -u ${user} -p ${pass}

11.运行

~/greenplum/bin/gpinitsystem -c ~/greenplum/initgp_config 

当显示的结果中有，“Greenplum Database instance successfully created”即安装成功。

即可以使用psql -p 2345 -d postgres进行访问。
