Postgresql-XL安装部署
机器准备：
3台虚拟机信息：

安装(三台虚机同时按下面步骤安装)：
1、下载源码：官方下载，网盘下载。
2、解压源码
tar xvf postgres-xl-v9.2-src.tar.gz3、编译安装
./configure --prefix=/opt/pgxl make make install注：编译过程中出现的问题（centos5会出现此问题，6则不会）：
'/usr/bin/perl' /bin/collateindex.pl -f -g -i 'bookindex' -o bookindex.sgml HTML.index Can't open perl script "/bin/collateindex.pl": No such file or directory make[4]: *** [bookindex.sgml] Error 2 make[4]: Leaving directory `/root/postgres-xl/doc-xc/src/sgml' make[3]: *** [sql_help.h] Error 2 make[3]: Leaving directory `/root/postgres-xl/src/bin/psql' make[2]: *** [all-psql-recurse] Error 2 make[2]: Leaving directory `/root/postgres-xl/src/bin' make[1]: *** [all-bin-recurse] Error 2 make[1]: Leaving directory `/root/postgres-xl/src' make: *** [all-src-recurse] Error 2解决方法：
#yum install docbook-style-dsssl #find / -name collateindex.pl /usr/bin/collateindex.pl #cp /usr/bin/collateindex.pl /bin/节点部署：
新建用户（三台虚机依次操作，注意：一定要用相同的用户，否则会发生用户找不到的问题）：
[root@localhost opt]# useradd pgxl [root@localhost opt]# chown -R pgxl pgxl/ [root@localhost opt]# su pgxl [pgxl@localhost pgxl]$ ls bin data_gtm include lib share [pgxl@localhost pgxl]$ cd bin/ [pgxl@localhost bin]$ ls clusterdb createuser dropuser gtm_ctl initgtm pg_config pg_dump pg_resetxlog postmaster vacuumdb createdb dropdb ecpg gtm_proxy makesgml pg_controldata pg_dumpall pg_restore psql createlang droplang gtm initdb pg_basebackup pg_ctl pg_receivexlog postgres reindexdb [pgxl@localhost bin]$
初始化：
gtm初始化：[pgxl@localhost bin]$ ./initgtm -D /opt/pgxl/data_gtm/ -Z gtm
The files belonging to this GTM system will be owned by user "pgxl".
This user must also own the server process.
creating directory /opt/pgxl/data_gtm ... ok
creating configuration files ... ok
Success. You can now start the GTM server using:
./gtm -D /opt/pgxl/data_gtm
or
./gtm_ctl -Z gtm -D /opt/pgxl/data_gtm -l logfile start
[pgxl@localhost bin]$ node1初始化（initdb初始化过程和pg初始化过程一致，这里就不多赘述了）：
[pgxl@localhost bin]$ ./initdb -D /opt/pgxl/data/coordinator1/ --nodename coordinator1 [pgxl@localhost bin]$ ./initdb -D /opt/pgxl/data/datanode1/ --nodename datanode1 [pgxl@localhost bin]$ ./initgtm -D /opt/pgxl/data/gtm_proxy1/ -Z gtm_proxy The files belonging to this GTM system will be owned by user "pgxl". This user must also own the server process. creating directory /opt/pgxl/data/gtm_proxy1 ... ok creating configuration files ... ok Success. You can now start the GTM proxy server using: ./gtm_proxy -D /opt/pgxl/data/gtm_proxy1 or ./gtm_ctl -Z gtm_proxy -D /opt/pgxl/data/gtm_proxy1 -l logfile startnode2初始化：
