Greenplum 数据库安装部署(生产环境)
硬件配置:
16 台 IBM X3650,
节点配置:CPU 2 * 8core,内存 128GB,硬盘 16 * 900GB,万兆网卡。
万兆交换机。
安装需求:
1台Master,1台Standby Master,14台Segment计算节点。
安装步骤:
先确认各节点目录结构保持一致:
[root@XXXGPM01 db]# df -h
Filesystem Size Used Avail Use% Mounted on
/dev/sda6 20G 440M 18G 3% /
tmpfs 63G 76K 63G 1% /dev/shm

/dev/sda7 20G 5.8G 13G 32% /usr
/dev/sda10 9.7G 338M 8.8G 4% /var
主节点/etc/hosts文件,追加内容(万兆网卡的IP地址和主机名):

cd /data1; unzip /opt/db.zip
mkdir -p /data1/gpinstall
在 XXXGPM1 节点上,将 greenplum-db-4.x.x.x-build-5-RHEL5-x86_64.zip 解开, 以 root 用户执行得到的.bin 文件。按照提示进行安装。
# /bin/bash greenplum-db-4.3.2.0-build-1-RHEL5-x86_64.bin
选择自定义安装目录: /data1/gpinstall/greenplum-db-4.3.2.0
安装完成之后,可以看到如下目录
[root@XXXGPM01 gpinstall]# pwd
/data1/gpinstall
[root@XXXGPM01 gpinstall]# ls -lh
总用量 4.0K
lrwxrwxrwx. 1 root root 22 6月 4 18:51 greenplum-db -> ./greenplum-db-4.3.2.0
drwxr-xr-x. 11 root root 4.0K 6月 4 18:51 greenplum-db-4.3.2.0
mkdir -p /data1/gpinstall/config
创建两个配置文件

source /data1/gpinstall/greenplum-db/greenplum_path.sh
gpssh-exkeys -f /data1/gpinstall/config/allnodes.txt
测试可以正常互信。此时就可以方便的去同步配置所有的参数。
先写脚本同步各节点的/etc/hosts文件:
#!/bin/bash
#Usage: copy files to other hosts in cluster.
#ex: sh bulkcp.sh /etc/hosts /etc/hosts
#Author: AlfredZhao
#Version: 1.0.0
for((i=18;i<=33;i++))
do
scp $1 172.16.99.$i:$2
echo "scp $1 172.16.99.$i:$2"
done
gpssh -f /data1/gpinstall/config/allnodes.txt -e ‘‘ 回车即可进入交互性界面。
检查是否关闭及开机启动项设置:
service iptables status
service ip6tables status
service libvirtd status
service iptables stop
service ip6tables stop
service libvirtd stop
chkconfig libvirtd off
chkconfig iptables off
chkconfig ip6tables off
检查SELinux的当前状态和配置:
getenforce
more /etc/selinux/config | grep SELINUX=
临时关闭SELinux和永久禁用SELinux:
setenforce 0
sed -i ‘s/SELINUX=enforcing/SELINUX=disabled/g‘ /etc/selinux/config
检查当前的磁盘调度算法:
cat /sys/block/sd*/queue/scheduler
原厂给的设置方法:
修改/boot/grub/menu.lst 找到 kernel /vmlinuz-xxx 这一行,在最后添加 elevator=deadline
检查/验证方法:
系统启动正常后,执行 cat /sys/block/*/queue/scheduler 应能看到: noop anticipatory [deadline] cfq
实际遇到问题:RHEL6.5系统 没有/boot/grub/menu.lst 这个文件。
nl /boot/grub/menu.lst
换一个思路,利用rc.local配置加两行信息如下:
echo deadline > /sys/block/sda/queue/scheduler
echo deadline > /sys/block/sdb/queue/scheduler
这里为了快速同步集群的配置统一,将这两行写入临时配置文件/tmp/gpconfig/1deadline.conf,然后同步到各节点。
mkdir -p /tmp/gpconfig
最后在交互性界面执行命令:
cat /tmp/gpconfig/1deadline.conf >> /etc/rc.d/rc.local
检查磁盘预读取设置,应都是 16384:
blockdev --getra /dev/sd* blockdev --getra /dev/dm-*
设置办法:
修改/etc/rc.d/rc.local 增加两行
blockdev --setra 16384 /dev/sd*
blockdev --setra 16384 /dev/dm-*
检查办法:
系统重启后,运行
blockdev --getra /dev/sd* blockdev --getra /dev/dm-*
应都是 16384
/etc/rc.d/rc.local
sh bulkcp.sh /tmp/gpconfig/2rclocal.conf /tmp/gpconfig/2rclocal.conf
gpssh -f /data1/gpinstall/config/allnodes.txt -e ‘‘
cat /tmp/gpconfig/2rclocal.conf >> /etc/rc.d/rc.local
检查语言和字符集:echo $LANG
en_US.UTF-8
设置办法:系统安装时指定。
检查办法:登录系统,执行命令 locale 结果应该是 en_US.UTF-8
修改:
sed -i ‘s/zh_CN.UTF-8/en_US.UTF-8/g‘ /etc/sysconfig/i18n
配置sysctl.conf
sysctl -p
有时需要 modprobe bridge
设置办法: 修改/etc/sysctl.conf,
增加以下内容:
net.ipv4.ip_forward = 0
net.ipv4.conf.default.accept_source_route = 0
kernel.sysrq = 0
kernel.core_uses_pid = 1
net.ipv4.tcp_syncookies = 1
kernel.msgmnb = 65536
kernel.msgmax = 65536
kernel.sem = 250 64000 100 2048
kernel.shmmax = 5000000000
kernel.shmmni = 40960
kernel.shmall = 40000000000
net.ipv4.tcp_tw_recycle=1
net.ipv4.tcp_max_syn_backlog=4096
net.core.netdev_max_backlog=10000
vm.overcommit_memory=2
net.ipv4.conf.all.arp_filter = 1
net.ipv4.ip_local_port_range = 1025 65535
然后执行 sysctl -p。
vi /tmp/gpconfig/4sysctl.conf
sh bulckcp.sh /tmp/gpconfig/4sysctl.conf /tmp/gpconfig/4sysctl.conf
gpssh -f /data1/gpinstall/config/allnodes.txt -e ‘‘
cat /tmp/gpconfig/4sysctl.conf >> /etc/sysctl.conf
检查办法: 用 sysctl ,检查上述各参数是否匹配。
查看用户资源限额:
ulimit -a
设置办法:
修改 /etc/security/limits.d/90-nproc.conf
Replace with:
* soft nofile 1048576
* hard nofile 1048576
* soft nproc 1048576
* hard nproc 1048576
同步修改:
vi /tmp/gpconfig/5limits.conf
sh bulkcp.sh /tmp/gpconfig/5limits.conf /tmp/gpconfig/5limits.conf
nl /etc/security/limits.d/90-nproc.conf
cat /tmp/gpconfig/5limits.conf >> /etc/security/limits.d/90-nproc.conf
检查办法: 用任意普通用户登录,执行 ulimit -a,检查上述参数是否匹配。
检查时间:
date
校对时间:
--2015年6月5日9:17
date 060509172015
hwclock -w
确定需要启用的网卡:eth2
ifconfig eth2 | grep 172
more /etc/sysconfig/network-scripts/ifcfg-eth2 |grep ONBOOT
修改eth2网卡配置,开启自启动
sed -i ‘s/ONBOOT=no/ONBOOT=yes/g‘ /etc/sysconfig/network-scripts/ifcfg-eth2
以上步骤修改完毕后统一重启下机器,再次验证以上各个步骤是否修改成功。
这个也可以在gpseginstall时指定选项创建,这里为了规范业务用户的uid和gid事先先创建好组和用户:
写一个小脚本,分发到各节点,然后在交互式界面下统一执行脚本建立组,用户,密码:
#!/bin/bash
#Usage: create gpadmin
#Author: AlfredZhao
#version: 1.0.0
groupadd gpadmin -g 3030
useradd gpadmin -u 3030 -g 3030
passwd gpadmin <<EOF
> gpadminpwd
> gpadminpwd
> EOF
Master 目录:
gpssh -h XXXGPM01 -e ‘mkdir -p /data1/master‘
gpssh -h XXXGPM02 -e ‘mkdir -p /data1/master‘
gpssh -h XXXGPM01 -e ‘chown gpadmin:gpadmin /data1/master‘
gpssh -h XXXGPM02 -e ‘chown gpadmin:gpadmin /data1/master‘
数据库数据文件存储目录:
注意这里配置文件变为nodes.txt,主节点并不需要创建这些目录。
gpssh -f /data1/gpinstall/config/nodes.txt -e ‘‘
mkdir -p /data1/primary
mkdir -p /data1/mirror
mkdir -p /data2/primary
mkdir -p /data2/mirror
chown gpadmin:gpadmin /data1/primary
chown gpadmin:gpadmin /data1/mirror
chown gpadmin:gpadmin /data2/primary
chown gpadmin:gpadmin /data2/mirror
gpseginstall -f allnodes.txt -c csv
如果前面没有手工提前建立gpadmin用户,这里可以指定用户密码(-u -p),统一建立gpadmin用户和密码
[root@XXXGPM01 data1]# gpseginstall -f /data1/gpinstall/config/allnodes.txt -c csv
