第一部分 - Linux Configuration 「所有节点」

Add User 「所有节点执行」添加用户

groupadd -g 530 gpadmin
useradd -g 530 -u 530 -m -d /home/gpadmin -s /bin/bash gpadmin
chown -R gpadmin.gpadmin /home/gpadmin
echo "gpadmin" | passwd --stdin gpadmin

关闭 SELinux 、 iptables

cat /etc/selinux/config | grep "^SELINUX="

SELINUX=disabled

sestatus # 查看当前SeLinux配置是 disabled

/etc/init.d/iptables status

chkconfig --list | grep iptables | grep on

Yum 「防止初始化失败，ed 命令来修改配置文件」

yum install ed -y

配置主机名 hosts

vim /etc/hosts

127.0.0.1   localhost localhost.localdomain localhost4  localhost4.localdomain4
::1         localhost localhost.localdomain localhost6  localhost6.localdomain6
172.24.3.76  dbaone
172.24.3.77  dbatwo
172.24.3.78  dbathree
172.24.3.79  dbafour

scp /etc/hosts dbaone:/etc
scp /etc/hosts dbatwo:/etc
scp /etc/hosts dbathree:/etc
scp /etc/hosts dbafour:/etc

配置内核参数

vim /etc/sysctl.conf

#xfs_mount_options = rw,noatime,inode64,allocsize=16m   # 因为使用不是xfs，所以注释此行kernel.shmmax = 500000000

net.core.wmem_max = 2097152
#vm.overcommit_memory = 2     ### 测试环境要取消这个，否则oracle启不来 ### 值为1

sysctl -p

配置资源限制

vim /etc/security/limits.conf

soft nofile 65536* hard nofile 65536
soft nproc 131072
hard nproc 131072

vim /etc/security/limits.d/90-nproc.conf # 「将1024 修改为131072」

soft nofile 65536
hard nofile 65536
soft nproc 131072
hard nproc 131072

XFS 分区

yum install xfsprogs

mkfs.xfs -f /dev/[device]

vim /etc/fstab # 后2位是 1 1 吗？

 /dev/[device] /[partition] xfs rw,noatime,inode64,allocsize=16m 0 0

设置Linux调度器规则，默认为 CFQ ，更改为 deadline

cat /sys/block/{devname}/queue/scheduler

noop anticipatory [deadline] cfq

echo deadline > /sys/block/{devname}/queue/scheduler

固化配置
cat /etc/rc.d/rc.local

echo deadline > /sys/block/**{devname**/queue/scheduler

禁用 Transparent Huge Pages (THP)

创建数据目录「gpmaster保存Master数据，每个机器gpdata1、gpdata2分别对应这个机器的两个主数据节点(Primary)，gpdatam1、gpdatam2对应备数据节点(Mirror)」

gpssh -f /opt/greenplum/greenplum-db/conf/hostlist -e -v "mkdir -p /opt/greenplum/greenplum-db/gpdata/{gpmaster,gpdatap1,gpdatap2,gpdatam1,gpdatam2}"

配置环境变量

$ gpssh -f /opt/greenplum/greenplum-db/conf/hostlist -e -v "cat >> /home/gpadmin/.bash_profile <<EOF

source /opt/greenplum/greenplum-db/greenplum_path.sh
export MASTER_DATA_DIRECTORY=/opt/greenplum/greenplum-db/gpdata/gpmaster/gpseg-1
export GPPORT=5432
export PGDATABASE=testDB
EOF"

. .bash_profile

系统参数校验："$PGHOME/etc/gpcheck.cnf"

gpcheck -f /opt/greenplum/greenplum-db/conf/hostlist

网络测试

gpcheckperf -d /tmp/ upload -r N -f /opt/greenplum/greenplum-db/conf/seg_hosts

gpcheckperf -d /tmp/ upload -r N -h dbathree -h dbafour # "单独测试2台机器网络"

文件系统测试

gpcheckperf -f seg_hosts -d /opt/greenplum/greenplum-db/gpdata/gpdatap1 -d /opt/greenplum/greenplum-db/gpdata/gpdatap2 -d /opt/greenplum/greenplum-db/gpdata/gpdatam1 -d /opt/greenplum/greenplum-db/gpdata/gpdatam2 -r ds

初始化 Greenplum 配置文件
配置文件模板都在 /opt/greenplum/greenplum-db/docs/cli_help/gpconfigs
gpinitsystem_config 是初始化 Greenplum 的模板，此模板中 Mirror Segment的配置都被注释

[gpadmin@dbaone ~]$ cd /opt/greenplum/greenplum-db/docs/cli_help/gpconfigs

$ cp gpinitsystem_config initgp_config

$ vim initgp_config

ARRAY_NAME="EMC Greenplum DW"
MACHINE_LIST_FILE=/opt/greenplum/greenplum-db/conf/seg_hosts
SEG_PREFIX=gpseg
PORT_BASE=40000
declare -a DATA_DIRECTORY=(/opt/greenplum/greenplum-db/gpdata/gpdatap1 /opt/greenplum/greenplum-db/gpdata/gpdatap2)
MASTER_HOSTNAME=dbaone
MASTER_DIRECTORY=/opt/greenplum/greenplum-db/gpdata/gpmaster
MASTER_PORT=5432
TRUSTED_SHELL=ssh
CHECK_POINT_SEGMENTS=8
ENCODING=UNICODE
MIRROR_PORT_BASE=50000
REPLICATION_PORT_BASE=41000
MIRROR_REPLICATION_PORT_BASE=51000
declare -a MIRROR_DATA_DIRECTORY=(/opt/greenplum/greenplum-db/gpdata/gpdatam1 /opt/greenplum/greenplum-db/gpdata/gpdatam2)

初始化pg，-s 表示 standby master，若gp版本为3.8.0 不要在初始化加 standby master。

备份方案有2种（Grouped Miior、Spread Mirror）,-S 表示使用Spread Mirror 分配 mirror节点，防止一个节点挂掉，另外一个节点集中成为瓶颈！ P301

[gpadmin@dbaone gpconfigs]$ gpinitsystem -c initgp_config -s dbafour -S

$ gpinitsystem -c initgp_config -S

若初始化失败，需要删除数据目录重新来
gpssh -f /opt/greenplum/greenplum-db/conf/hostlist -e -v "cd /opt/greenplum/greenplum-db/gpdata/ && rm -rf gpmaster/* && rm -rf gpdatap1/* && rm -rf gpdatap2/* && rm -rf gpdatam1/* && rm -rf gpdatam2/* "

Greenplum 配置

1>、配置远程可登陆

[gpadmin@dbaone ~]$ psql postgres
psql (8.2.15)
Type "help" for help.

testdb=# alter role gpadmin with password 'gpadmin';
ALTER ROLE

为了保证与standby master 配置文件一致，standby master的配置文件也要修改！

[gpadmin@dbaone ~]$ vim $MASTER_DATA_DIRECTORY/pg_hba.conf

host all gpadmin 0.0.0.0/0 md5

[gpadmin@four ~]$ vim $MASTER_DATA_DIRECTORY/pg_hba.conf

host all gpadmin 0.0.0.0/0 md5

使配置生效！

启动与关闭数据库「-a 不会手动输入yes了」

$ gpstart -a

$ gpstop -a

reload 配置文件

第三部分 - 图形工具 GUI

 Navicat Premium
 
 pgAdmin

      http://www.pgadmin.org/download/?lang=zh_CN

      http://www.postgresql.org/ftp/pgadmin3/release/

保存密码
警告：你已经选择了保存密码，在 *nix 下它将被保存在 home 目录的纯文本文件中，而在 Windows 系统下它将被保存在用户的配置文件中。如果你不想这么做，请点击 Cancel 按钮。
pgAdmin 使用 PostgreSQL 的 'pgpass' 机制保存密码。在 *nix 系统下，密码将被保存在 ~/.pgpass 文件中；而在 Windows 系统下，它将被保存在 %APPDATA%\PostgreSQL\pgpass.conf 文件中（%APPDATA% 是位于用户配置文件之内的 'Application Data' 文件夹）。这个机制被用来作为使用 libpg 库连接数据库服务器的所有程序的缺省机制，包括命令行程序（例如 pg_dump 和 pg_restore）、其他 GUI 程序、驱动程序（例如： psqlODBC）。这意味着这些程序都可以使用这个保存的密码自动连接到数据库，如果你不想这样做，不要使用 pgAdmin 的 Store Password 的选项。

第四部分 -- Standby Master

添加 Standby Master

参考：greenplum数据库master节点搭建standby

删除 standby master

 gpinitstandby -r

重新同步 Standby Master「若已有 Standby Master，但这个节点已经不同步了，需要重启同步」

 gpinitstandby -n

查看 Standby Master 是否同步

GP 4.1
testdb=# select * from gp_master_mirroring;

GP 4.3
testdb=# select procpid,state from pg_stat_replication;
procpid | state
---------+-----------
1806 | streaming
