AntDB上使用uuid

安装uuid相关依赖

sudo yum install -y uuid*

停止集群

adbmgr 进入：
stop all mode fast;
stop agent all;

重新编译antdb

 ../antdb/configure --prefix=/home/adb/antdb/app --with-ossp-uuid --with-perl --with-python --with-openssl --with-pam --with-ldap --with-libxml --with-libxslt --enable-thread-safety --enable-debug --enable-cassert CFLAGS="-DWAL_DEBUG -O2 -ggdb3 -fsigned-char"

make install-world-contrib-recurse  

configure 参数需要添加：–with-ossp-uuid

在adbhome下查找uuid相关文件

[adb@bogon ~]$ find antdb/app -name 'uuid*'
antdb/app/lib/postgresql/uuid-ossp.so
antdb/app/share/postgresql/extension/uuid-ossp--1.1.sql
antdb/app/share/postgresql/extension/uuid-ossp--unpackaged--1.0.sql
antdb/app/share/postgresql/extension/uuid-ossp.control
antdb/app/share/postgresql/extension/uuid-ossp--1.0--1.1.sql
antdb/app/include/postgresql/server/utils/uuid.h
[adb@bogon ~]$ 

启动antdb集群

adbmgr 进入：
deploy all;
start agent all;
start all;

记得要进行deploy，保证各个主机上的adbhome下都有uuid相关文件

创建uuid扩展

postgres=# create extension "uuid-ossp";
CREATE EXTENSION
postgres=# select * from pg_extension ;
  extname  | extowner | extnamespace | extrelocatable | extversion | extconfig | extcondition 
-----------+----------+--------------+----------------+------------+-----------+--------------
 plpgsql   |       10 |           11 | f              | 1.0        |           | 
 uuid-ossp |       10 |         2200 | t              | 1.1        |           | 
(2 rows)

uuid已经安装成功。

查看uuid相关函数

postgres=# \df uuid_*
