2.1.评估存储能力
2.1.1.计算可用的空间
步骤1：初始存储能力=硬盘大小*硬盘数
步骤2：配置RAID10，格式化磁盘空间=(初始存储能力*0.9)/2
步骤3：可用磁盘空间=格式化磁盘空间*0.7
步骤4：用户数据使用空间
使用镜像：(2*用户数据)+用户数据/3=可用磁盘空间
不使用镜像：用户数据+用户数据/3=可用磁盘空间
2.1.2.计算用户数据大小
平均来说，实际占用磁盘空间大小=用户数据*1.4
页面开销：32KB页面需要20 bytes
行开销：每行24 bytes，‘append-only‘表需要4bytes
索引开销：
B-tree:唯一值*(数据类型大小+24bytes)
Bitmap:(唯一值*行数*1bit*压vi缩比率/8)+(唯一值*32)
为元数据和日志计算空间需求
系统元数据：20M
预写日志(WAL)：WAL被拆分成多个64M的文件，WAL文件数最多为
2*checkpoint_segments+1，checkpoint_segments默认值为8。也就意味着每个实例需要1088MB的WAL空间
GP数据库日志文件：日志轮转
性能监控数据

修改主机名和IP映射：
|
[[email protected] ~]# vi /etc/sysconfig/network NETWORKING=yes NETWORKING_IPV6=no HOSTNAME=master [[email protected] ~]# vi /etc/hosts # Do not remove the following line, or various programs # that require network functionality will fail. 127.0.0.1 localhost.localdomain localhost ::1 localhost6.localdomain6 localhost6 192.168.80.200 master |
2.2.3.3.系统参数配置
包括共享内存、网络、用户限制等，修改或添加/etc/sysctl.conf
|
# Kernel sysctl configuration file for Red Hat Linux # For binary values, 0 is disabled, 1 is enabled.

2.2.3.4.系统设置（所有节点）
配置/etc/security/limits.conf文件
|
# for greenplum begin * soft nofile 65536 * hard nofile 65536 * soft nproc 131072 * hard nproc 131072 # for greenplum end |
设置磁盘访问I/O调度策略
说明：介绍文章：http://blog.csdn.net/theorytree/article/details/6259104
deadline的调度策略可以平衡IO调度和进程调度，不会造成等待进程频繁的等待
|
[[email protected] ~] # cat /sys/block/sda/queue/scheduler noop anticipatory deadline [cfq] [[email protected] ~] # cat /sys/block/fd0/queue/scheduler noop anticipatory deadline [cfq] [[email protected] ~]# dmesg | grep -i scheduler io scheduler noop registered io scheduler anticipatory registered io scheduler deadline registered io scheduler cfq registered (default) |
|
[[email protected] ~]# echo deadline > /sys/block/sda/queue/scheduler [[email protected] ~]# echo deadline > /sys/block/fd0/queue/scheduler [[email protected] ~]# cat /sys/block/sda/queue/scheduler noop anticipatory [deadline] cfq [[email protected] ~]# cat /sys/block/fd0/queue/scheduler noop anticipatory [deadline] cfq |
设置预读块的值为16384;
16384：数据仓库的最大特点是用于保存历史数据，存在大量的数据操作，包括增删改查，当设置的块越大时读取性能越高；16384是greenplum数据库要求的最低要求。
|
[[email protected] ~]# /sbin/blockdev --setra 16384 /dev/sda [[email protected] ~]# /sbin/blockdev --setra 16384 /dev/sda1 [[email protected] ~]# /sbin/blockdev --setra 16384 /dev/sda2 [[email protected] ~]# /sbin/blockdev --setra 16384 /dev/sda3 [[email protected] ~]# fdisk -l Disk /dev/sda: 21.4 GB, 21474836480 bytes 255 heads, 63 sectors/track, 2610 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Device Boot Start End Blocks Id System /dev/sda1 * 1 653 5245191 83 Linux /dev/sda2 654 914 2096482+ 82 Linux swap / Solaris /dev/sda3 915 1045 1052257+ 83 Linux |
修改/etc/hosts，添加如下内容
|
127.0.0.1 localhost.localdomain localhost ::1 localhost6.localdomain6 localhost6 192.168.80.200 master 192.168.80.201 slave1 192.168.80.202 slave2 |

2.2.5.验证操作系统设置
2.2.5.1.创建存储区域
a) 创建Master数据存储区域
# mkdir -p /data/master
b) 改变目录的所有权
# chown gpadmin /data/master
c) 创建一个包含所有segment主机的文件seg_hosts
|
[[email protected] ~]# mkdir /tmp/greenplum [[email protected] ~]# cd /tmp/greenplum/ [[email protected] greenplum]# vi seg_hosts slave1 slave2 "seg_hosts" [New] 2L, 14C written [[email protected] greenplum]# cat seg_hosts slave1 slave2 |
d) 使用gpssh工具在所有segment主机上创建主数据和镜像数据目录
|
[[email protected] greenplum]# . /usr/local/greenplum-db/greenplum_path.sh [[email protected] greenplum]# gpssh -f seg_hosts -e ‘mkdir -p /data/primary‘ [slave1] mkdir -p /data/primary [slave2] mkdir -p /data/primary [[email protected] greenplum]# gpssh -f seg_hosts -e ‘mkdir -p /data/mirror‘ [slave1] mkdir -p /data/mirror [slave2] mkdir -p /data/mirror [[email protected] greenplum]# gpssh -f seg_hosts -e ‘chown gpadmin /data/primary‘ [slave1] chown gpadmin /data/primary [slave2] chown gpadmin /data/primary [[email protected] greenplum]# gpssh -f seg_hosts -e ‘chown gpadmin /data/mirror‘ [slave1] chown gpadmin /data/mirror [slave2] chown gpadmin /data/mirror |
2.2.5.2.同步系统时间
a) 在Master主机上编辑/etc/ntp.conf来设置如下内容：
|
[[email protected] greenplum]# cat /etc/ntp.conf # Permit time synchronization with our time source, but do not # permit the source to query or modify the service on this system. restrict default kod nomodify notrap nopeer noquery restrict -6 default kod nomodify notrap nopeer noquery # Permit all access over the loopback interface.

b) 在Segment主机上编辑/etc/ntp.conf
|
# Undisciplined Local Clock. This is a fake driver intended for backup # and when no outside source of synchronized time is available. #server 127.127.1.0 # local clock server master # local clock fudge 127.127.1.0 stratum 10 |
c) 在Master主机上，通过NTP守护进程同步系统时钟
|
