3.3、安装cmake3.x
[root@rhmdw soft]# sh cmake-3.13.4-Linux-x86_64.sh
CMake Installer Version: 3.13.4, Copyright (c) Kitware
......
Do you accept the license? [yN]:
y
By default the CMake will be installed in:
"/soft/cmake-3.13.4-Linux-x86_64"
Do you want to include the subdirectory cmake-3.13.4-Linux-x86_64?
Saying no will install in: "/soft" [Yn]:
y
......
[root@rhmdw soft]# mv cmake-3.13.4-Linux-x86_64 /usr/bin/
[root@rhmdw soft]# ln -sf /usr/bin/cmake-3.13.4-Linux-x86_64/bin/cmake /usr/bin/cmake
3.4 配置时间同步
3.5 调整CPU调度模式，调整deadline，rhel 7 3.6 默认为该模式
3.6 修改磁盘预读参数
blockdev --setra 65535 /dev/sda
echo "blockdev --setra 65535 /dev/sda" >> /etc/rc.d/rc.local
=============================++++++++++++++
203 未配置，确定是否可以永久修改
4、mdw 安装greenplum
4.1、

4.2、配置互信
[gpadmin@rhmdw config]$ gpssh-exkeys -f hostlist
[STEP 1 of 5] create local ID and authorize on local host
... /home/gpadmin/.ssh/id_rsa file exists ... key generation skipped
[STEP 2 of 5] keyscan all hosts and update known_hosts file
[STEP 3 of 5] authorize current user on remote hosts
... send to rhsdw1
***
*** Enter password for rhsdw1:
... send to rhsdw2
[STEP 4 of 5] determine common authentication file content
[STEP 5 of 5] copy authentication files to all remote hosts
... finished key exchange with rhsdw1
... finished key exchange with rhsdw2
[INFO] completed successfully
4.3、互信验证
[gpadmin@rhmdw config]$ gpssh -f /gp/app/config/hostlist -e 'pwd'
[ rhmdw] pwd
[ rhmdw] /home/gpadmin
[rhsdw1] pwd
[rhsdw1] /home/gpadmin
[rhsdw2] pwd
[rhsdw2] /home/gpadmin
5、通过master端安装seg端软件：
******该方式可以跳过rhmdw的安装 ++++++++快照点
5.1、
[gpadmin@rhmdw config]$ gpseginstall -f hostlist -u gpadmin -p gpadmin
......
20190305:11:34:14:014689 gpseginstall:rhmdw:gpadmin-[INFO]:-SUCCESS -- Requested commands completed
5.2、验证
[gpadmin@rhmdw config]$ gpssh -f /gp/app/config/hostlist -e 'ls -lrt /gp/app'
5.3、配置seg环境变量
[gpadmin@rhmdw config]$ scp ~/.bash_profile rhsdw1:/home/gpadmin/
.bash_profile 100% 228 260.7KB/s 00:00
[gpadmin@rhmdw config]$ scp ~/.bash_profile rhsdw2:/home/gpadmin/
.bash_profile
5.4、相关主机上创建相关目录
[gpadmin@rhmdw config]$ cd /gp/
[gpadmin@rhmdw gp]$ mkdir -p gpdata/master
[gpadmin@rhmdw gp]$ gpssh -f /gp/app/config/seg_host -e 'mkdir -p /gp/gpdata/primary'
[rhsdw1] mkdir -p /gp/gpdata/primary
[rhsdw2] mkdir -p /gp/gpdata/primary
[gpadmin@rhmdw gp]$ gpssh -f /gp/app/config/seg_host -e 'mkdir -p /gp/gpdata/mirror'
[rhsdw2] mkdir -p /gp/gpdata/mirror
[rhsdw1] mkdir -p /gp/gpdata/mirror
6、系统检测
6.1、初始化数据库前检测master 参数检测，该问题可跳过
[gpadmin@rhmdw gp]$ gpcheck -f /gp/app/config/hostlist -m rhmdw

重新调整gp mount选项
nodev,noatime,inode64,allocsize=16m
参数性能检查
gpcheck -f /gp/app/config/hostlist -m mdw -s smdw
核对并修改下你感应系统参数。
2 性能检查
2.1 网络性能检查
gpcheckperf -f /gp/app/config/hostlist -r N -d /tmp > checknetwork.out
2.2 磁盘性能检查
gpcheckperf -f /gp/app/config/hostlist -r ds -D -d /gp/gpdata/primary -d /gp/gpdata/mirror r > checkio.out
检查磁盘IO的目标目录是数据库的数据文件目录，测试工具会写入系统内存的两倍大小的数据量。

7、创建GreenPlum数据库的参数文件(仅Master节点)
cp app/docs/cli_help/gpconfigs/gpinitsystem_config /gp/app/config/
[gpadmin@rhmdw config]$ more /gp/app/config/gpinitsystem_config | egrep -v "(^#|^$)"
ARRAY_NAME="Greenplum Data Platform"
SEG_PREFIX=gpseg
PORT_BASE=6000
declare -a DATA_DIRECTORY=(/gp/gpdata/primary)
MASTER_HOSTNAME=rhmdw
MASTER_DIRECTORY=/gp/gpdata/master
MASTER_PORT=5432
TRUSTED_SHELL=ssh
CHECK_POINT_SEGMENTS=8
ENCODING=UNICODE
ARRAY_NAME：设置阵列名称，默认EMC Greenplum DW。
SEG_PREFIX：设置segment的前缀，默认gpseg。
PORT_BASE：设置segment的起始端口，会从此端口往上增加，默认从40000开始。
DATA_DIRECTORY：设置segment primary的数据存储目录，有几个segment节点就需要设置几个数据存储目录。
MASTER_HOSTNAME：设置master的主机名。
MASTER_DIRECTORY：设置master的存储目录。
MASTER_PORT：设置master的端口，默认5432。
TRUSTED_SHELL：设置节点之间的信任方式，默认SSH。
CHECK_POINT_SEGMENTS：预写日志文件（WAL）数量，默认为8，这意味着为主机上的每个Segment或Master实例分配1088MB的WAL空间。
ENCODING=UNICODE：设置初始字符集，默认UNICODE（UTF-8）。
8、初始化数据库 master
[gpadmin@rhmdw config]$ gpinitsystem -c /gp/app/config/gpinitsystem_config -h seg_host
-c：指定初始化文件。
-h：指定segment主机文件。
-s：指定standby主机，创建standby节点。
