# ./configure.py --bootstrap
# ln -s /root/ninja/ninja /usr/bin/ninja安装 gporca
这里啰嗦两句，gporca是 greenplum 新一代的优化器，在性能上有很大提升
legacy是早期针对单节点 greenplum 而构建的，主要应用于OLTP场景，greenplum在不安装orca的情况下使用的是legacy优化器。
为什么要有两个优化器，其实都是有历史原因的，现在的greenplum使用MPP，主要应用场景变为OLAP场景，legacy对此虽然进行了修改，但是从架构设计上，使得其维护和添加新的功能越来越困难，所以有了GPORCA优化器。
1、手动单独安装gporca （所有节点）
参考
https://github.com/greenplum-db/gporca
https://github.com/greenplum-db/gporca.git
# cd /root
# git clone https://github.com/greenplum-db/gporca.git
# cd gporca
# cmake -GNinja -H. -Bbuild
# ninja install -C build
--
--
-- Installing: /usr/local/include/gpopt/version.h
待安装完成后，进入/gporca/build目录，执行ctest命令进行检查,确保100% tests passed
# cd /root/gporca/build/
# /root/cmake/bin/ctest
100% tests passed, 0 tests failed out of 157
Total Test time (real) = 194.05 sec2、自动安装,其实最后都是拷贝文件到 /usr/local/include/ /usr/local/lib/
（所有节点）

===================================================================
Orca can now be installed on the local system using "make install"
and be used as any normal system library
If you'd rather compile GPDB using ORCA in it's current location and then
install ORCA into the gpdb installation location then first run the top
level configure as follows:
LD_LIBRARY_PATH=/tmp/gpdb-5.7.0/depends/build/lib ./configure
--with-libraries=/tmp/gpdb-5.7.0/depends/build/lib
--with-includes=/tmp/gpdb-5.7.0/depends/build/include
Then run "make".
Then run "LD_LIBRARY_PATH=/tmp/gpdb-5.7.0/depends/build/lib make install"
These steps should work on both MacOS and Linux

最后两条命令就是拷贝到系统路径里
# /bin/mkdir -p /usr/local

后来在 gpdb configure 的时候报了如下错误
checking Checking ORCA version... configure: error: Your ORCA version is expected to be 2.55.XXX
发现 gporca 的版本是 2.55.13 ，后来通过 第一种方式编译 gporca的版本为 2.55.20，没有再报错重装gporca前清空

SEG_PREFIX：设置segment的前缀，默认gpseg。
PORT_BASE：设置segment的起始端口，会从此端口往上增加，默认从40000开始。
DATA_DIRECTORY：设置segment primary的数据存储目录，有几个segment节点就需要设置几个数据存储目录。
MASTER_HOSTNAME：设置master的主机名。
MASTER_DIRECTORY：设置master的存储目录。
MASTER_PORT：设置master的端口，默认5432。
TRUSTED_SHELL：设置节点之间的信任方式，默认SSH。
CHECK_POINT_SEGMENTS：预写日志文件（WAL）数量，默认为8，这意味着为主机上的每个Segment或Master实例分配1088MB的WAL空间。
ENCODING=UNICODE：设置初始字符集，默认UNICODE（UTF-8）。
MACHINE_LIST_FILE：仅包含segment主机地址
注意，其中所有需要的目录都是在创建数据存储区域时做好的。gp初始化工具

熟悉吧，和 postgresql 的目录基本是一致的。
$ vi pg_hba.conf
$ psql -d postgres -c "select pg_reload_conf();"
$ psql -d postgres
psql (8.3.23)
Type "help" for help.
postgres=#
补充一下
$ gpinitsystem -c /usr/local/greenplum-db/gpinitsystem_config -h /usr/local/greenplum-db/all_host-h 应该是 /usr/local/greenplum-db/all_segment，当时拷贝错了，事后才发现。有空再重做一遍，增加下熟练度。
再次提醒自己，要细心，要细心，要细心
