一、环境配置
1、地址分配
192.168.1.201 mdw master 192.168.1.202 sdw1 segment1 192.168.1.203 sdw2 segment2
2、创建用户及用户组
$ groupadd -g gpadmin $ useradd gpadmin -u -g gpadmin $ passwd gpadmin
3、系统配置
- 在/etc/sysctl.conf 文件中加入有关共享内存与网络参数配置;执行 sysctl -p;使之生效
kernel.shmmax = kernel.shmmni = kernel.shmall = kernel.sem = kernel.sysrq = kernel.core_uses_pid = kernel.msgmnb = kernel.msgmax = kernel.msgmni = net.ipv4.tcp_syncookies = net.ipv4.ip_forward = net.ipv4.conf. net.ipv4.tcp_tw_recycle = net.ipv4.tcp_max_syn_backlog = net.ipv4.conf.all.arp_filter = net.ipv4.ip_local_port_range = net.core.netdev_max_backlog = net.core.rmem_max = net.core.wmem_max = vm.overcommit_memory =
- 在/etc/security/limits.conf 中加入限制参数
* soft nofile * hard nofile * soft nproc * hard nproc
- 编辑设备块大小
[root@localhost block]# blockdev --setra /dev/sda [root@localhost block]# blockdev --getra /dev/sda [root@localhost block]# more /sys/block/sda/queue/scheduler noop anticipatory deadline [cfq] [root@localhost block]# echo deadline > /sys/block/sda/queue/scheduler [root@localhost block]# more /sys/block/sda/queue/scheduler noop anticipatory [deadline] cfq
二、安装
1、安装数据库软件
软件下载地址：https://network.pivotal.io/products/pivotal-gpdb
[root@mdw software]# unzip greenplum-db--RHEL5-x86_64.zip [root@localhost software]# ./greenplum-db--RHEL5-x86_64.bin ******************************************************************************** Do you accept the Pivotal Database license agreement? [yes|no] ******************************************************************************** yes ******************************************************************************** Provide the installation path for Greenplum Database or press ENTER to accept the default installation path: /usr/local/greenplum-db-4.3.8.1 ******************************************************************************** /usr/local/greenplum-db438 ******************************************************************************** Install Greenplum Database into </usr/local/greenplum-db438>? [yes|no] ******************************************************************************** yes ******************************************************************************** /usr/local/greenplum-db438 does not exist. Create /usr/local/greenplum-db438 ? [yes|no] (Selecting no will exit the installer) ******************************************************************************** yes Extracting product to /usr/local/greenplum-db438 ******************************************************************************** Installation complete. Greenplum Database is installed in /usr/local/greenplum-db438 Pivotal Greenplum documentation is available for download at http://docs.gopivotal.com/gpdb ********************************************************************************
进入安装目录下cd /usr/local/greenplum；配置环境变量vi .bashrc
export GPHOME=/usr/local/greenplum-db438export PYTHONHOME="$GPHOME/ext/python"export PYTHONPATH=$GPHOME/lib/pythonexport PATH=$GPHOME/bin:$PYTHONHOME/bin:$PATHexport LD_LIBRARY_PATH=$GPHOME/lib:$PYTHONHOME/lib:$LD_LIBRARY_PATHexport OPENSSL_CONF=$GPHOME/etc/openssl.cnf
2、配置hostlist文件
[gpadmin@mdw config]$ cat hostlist mdw sdw1 sdw2 [gpadmin@mdw config]$ cat seg_hosts sdw1 sdw2
3、使用gpssh-exkeys打通所有服务器；
[gpadmin@localhost conf]$ gpssh-exkeys -f hostlist [STEP of ] create local ID and authorize on local host ... /home/gpadmin/.ssh/id_rsa file exists ... key generation skipped [STEP of ] keyscan all hosts and update known_hosts file [STEP of ] authorize current user on remote hosts ... send to mdw ... send to sdw1 *** *** Enter password for sdw1: ... send to sdw2 [STEP of ] determine common authentication file content [STEP of ] copy authentication files to all remote hosts ... finished key exchange with mdw ... finished key exchange with sdw1 ... finished key exchange with sdw2 [INFO] completed successfully
4、安装到各个机器上
【注意；2-4步骤可以直接在root用户下操作；可以避免一些问题；见FAQ】;当然这步可以手动操作；
[root@localhost greenplum]# gpseginstall -f /home/gpadmin/conf/hostlist -u gpadmin -p li0924 :::: gpseginstall:localhost:root-[INFO]:-Installation Info: link_name greenplum-db binary_path /usr/local/greenplum binary_dir_location /usr/local binary_dir_name greenplum :::: gpseginstall:localhost:root-[INFO]:-check cluster password access *** Enter password for mdw: :::: gpseginstall:localhost:root-[INFO]:-de-duplicate hostnames :::: gpseginstall:localhost:root-[INFO]:-master hostname: localhost.localdomain :::: gpseginstall:localhost:root-[INFO]:-check for user gpadmin on cluster :::: gpseginstall:localhost:root-[INFO]:-add user gpadmin on master :::: gpseginstall:localhost:root-[INFO]:-add user gpadmin on cluster :::: gpseginstall:localhost:root-[INFO]:-chown -R gpadmin:gpadmin /usr/local/greenplum-db :::: gpseginstall:localhost:root-[INFO]:-chown -R gpadmin:gpadmin /usr/local/greenplum :::: gpseginstall:localhost:root-[INFO]:-rm -f /usr/local/greenplum.tar; rm -f /usr/local/greenplum.tar.gz :::: gpseginstall:localhost:root-[INFO]:-cd /usr/local; tar cf greenplum.tar greenplum :::: gpseginstall:localhost:root-[INFO]:-gzip /usr/local/greenplum.tar :::: gpseginstall:localhost:root-[INFO]:-remote command: mkdir -p /usr/local :::: gpseginstall:localhost:root-[INFO]:-remote command: rm -rf /usr/local/greenplum :::: gpseginstall:localhost:root-[INFO]:-scp software to remote location :::: gpseginstall:localhost:root-[INFO]:-remote command: gzip -f -d /usr/local/greenplum.tar.gz :::: gpseginstall:localhost:root-[INFO]:-md5 check on remote location :::: gpseginstall:localhost:root-[INFO]:-remote command: cd /usr/local; tar xf greenplum.tar :::: gpseginstall:localhost:root-[INFO]:-remote command: rm -f /usr/local/greenplum.tar :::: gpseginstall:localhost:root-[INFO]:-remote command: cd /usr/local; rm -f greenplum-db; ln -fs greenplum greenplum-db :::: gpseginstall:localhost:root-[INFO]:-remote command: chown -R gpadmin:gpadmin /usr/local/greenplum-db :::: gpseginstall:localhost:root-[INFO]:-remote command: chown -R gpadmin:gpadmin /usr/local/greenplum :::: gpseginstall:localhost:root-[INFO]:-rm -f /usr/local/greenplum.tar.gz :::: gpseginstall:localhost:root-[INFO]:-Changing system passwords ... :::: gpseginstall:localhost:root-[INFO]:-exchange ssh keys for user root :::: gpseginstall:localhost:root-[INFO]:-exchange ssh keys for user gpadmin :::: gpseginstall:localhost:root-[INFO]:-/usr/local/greenplum-db/./sbin/gpfixuserlimts -f /etc/security/limits.conf -u gpadmin :::: gpseginstall:localhost:root-[INFO]:-remote command: . /usr/local/greenplum-db/./greenplum_path.sh; /usr/local/greenplum-db/./sbin/gpfixuserlimts -f /etc/security/limits.conf -u gpadmin :::: gpseginstall:localhost:root-[INFO]:-version :::: gpseginstall:localhost:root-[INFO]:-remote command: . /usr/local/greenplum-db/./greenplum_path.sh; /usr/local/greenplum-db/./bin/gpssh --version :::: gpseginstall:localhost:root-[INFO]:-remote command: . /usr/local/greenplum/greenplum_path.sh; /usr/local/greenplum/bin/gpssh --version :::: gpseginstall:localhost:root-[INFO]:-SUCCESS -- Requested commands completed
5、创建目录；在每个节点；
#mdw [gpadmin@localhost ~]$ mkdir -p /home/gpadmin/gpdata/pgmaster #sdw1 sdw2 [gpadmin@localhost ~]$ mkdir -p /home/gpadmin/gpdata/gpdatap [gpadmin@localhost ~]$ mkdir -p /home/gpadmin/gpdata/gpdatam
6. 参数监测；还有网络/io监测；
gpadmin@localhost ~]$ gpcheck -f /home/gpadmin/conf/hostlist -m mdw -s sdw1 :::: gpcheck:localhost:gpadmin-[INFO]:-dedupe hostnames :::: gpcheck:localhost:gpadmin-[INFO]:-Detected platform: Generic Linux Cluster :::: gpcheck:localhost:gpadmin-[INFO]:-generate data on servers :::: gpcheck:localhost:gpadmin-[INFO]:-copy data files from servers :::: gpcheck:localhost:gpadmin-[INFO]:-delete remote tmp files :::: gpcheck:localhost:gpadmin-[INFO]:-Using gpcheck config file: /usr/local/greenplum/etc/gpcheck.cnf :::: gpcheck:localhost:gpadmin-[ERROR]:-GPCHECK_ERROR host(None): utility will not check all settings when run as non-root user :::: gpcheck:localhost:gpadmin-[INFO]:-gpcheck completing...
三、初始化Greenplum
1、初始配置
[gpadmin@localhost ~]$ cp $GPHOME/docs/cli_help/gpconfigs/gpinitsystem_config config/gpinitsystem_config [gpadmin@localhost ~]$ chmod gpinitsystem_config
但是我这配置文件如下：
#数据库代号 ARRAY_NAME="EMC Greenplum DW" MACHINE_LIST_FILE=/home/gpadmin/conf/seg_hosts #Segment的名称前缀 SEG_PREFIX=gpseg #primary segment起始端口号 PORT_BASE= #指定primary segment的数据目录 declare -a DATA_DIRECTORY=(/home/gpadmin/gpdata/gpdatap) MASTER_HOSTNAME=mdw MASTER_DIRECTORY=/home/gpadmin/gpdata/gpmaster MASTER_PORT= #指定bash的版本 TRUSTED_SHELL=ssh #指定编码 ENCODING=UTF8 CHECK_POINT_SEGMENTS= #mirror segment起始端口号 MIRROR_PORT_BASE= #primary segment主备同步的起始端口号 REPLICATION_PORT_BASE= #mirror segment主备同步的起始端口号 MIRROR_REPLICATION_PORT_BASE= #mirror segment的数据目录 declare -a MIRROR_DATA_DIRECTORY=(/home/gpadmin/gpdata/gpdatam)
执行初始化命令
# -s sdw2 表示standby master指定的主机位置是sdw2

【FAQ】
1. 在执行“gpssh-exkeys -f hostlist”配置免密码登录时出现“[ERROR] ssl-keygen failed:”
解决方案： 执行 unset OPENSSL_CONF ；在执行命令可以避免
2. 执行“ gpseginstall -f /home/gpadmin/config/hostlist -u gpadmin -p li0924”结果失败；
分析：查看日志信息是“tar cf greenplum-db438.tar greenplum-db438”这步出错；很明显是没权限执行；前面有提示
解决方案：用root用户执行；或者直接手动去操作；这步骤就是把该目录复制到各个segment节点；避免在segement再进行安装
