title: Greenplum6单机安装攻略 date: 2019-07-18 11:10:27 categories: Greenplum
本文记录了GP安装的艰辛历程，本文重点记录了单机安装的流（cai）程（keng），多机集群的安装方法是类似的，使用不同的配置就好。踩坑无数，尽量严格按照下面顺序安装。
1 目录规划
这里有个技巧，可以用端口号命名文件夹，隔离不同的集群，例如后面你还可以用3500装另一个集群
源码目录：/home/mingjie.gmj/projects/gpdb
gp安装配置文件：/home/mingjie.gmj/gpconfigs/hostfile_gpinitsystem
gp安装配置文件：/home/mingjie.gmj/gpconfigs/gpinitsystem_config
master数据目录：/home/mingjie.gmj/databases/data/gpdata3400/master
segments数据目录：/home/mingjie.gmj/databases/data/gpdata3400/segments
2 系统参数
sudo vi /etc/sysctl.conf
kernel.shmmax = 500000000
kernel.shmmni = 4096
kernel.shmall = 4000000000
kernel.sem = 500 2048000 200 40960
kernel.sysrq = 1
kernel.core_uses_pid = 1
kernel.msgmnb = 65536
kernel.msgmax = 65536
kernel.msgmni = 2048
net.ipv4.tcp_syncookies = 1
net.ipv4.conf.default.accept_source_route = 0
net.ipv4.tcp_max_syn_backlog = 4096
net.ipv4.conf.all.arp_filter = 1
net.ipv4.ip_local_port_range = 10000 65535
net.core.netdev_max_backlog = 10000
net.core.rmem_max = 2097152
net.core.wmem_max = 2097152
vm.overcommit_memory = 2

sudo vi /etc/security/limits.conf
* soft nofile 524288
* hard nofile 524288
* soft nproc 131072
* hard nproc 131072
sudo vi /etc/ld.so.conf
/usr/local/lib
避免安装报错
echo "RemoveIPC=no" >> /etc/systemd/logind.conf
service systemd-logind restart
3 软件安装
下载源码
git clone https://github.com/greenplum-db/gpdb.git 6X_STABLE
# 安装依赖包
./README.CentOS.bash
cmake
装完了记得加PATH
wget -S https://github.com/Kitware/CMake/releases/download/v3.15.0-rc4/cmake-3.15.0-rc4.tar.gz
tar -xzvf cmake-3.15.0-rc4.tar.gz
./configure --prefix=/home/mingjie.gmj/bin/cmake315
make -sj32
make install
orca
cd depends/
./configure --prefix=/home/mingjie.gmj/bin/orca
make -sj32
make install_local
编译源码
LD_LIBRARY_PATH=/home/mingjie.gmj/bin/orca/lib ./configure --prefix=/home/mingjie.gmj/databases/gpsql3400 --with-pgport=3400 --with-perl --with-python --with-libxml --with-gssapi --with-includes=/home/mingjie.gmj/bin/orca/include --with-libraries=/home/mingjie.gmj/bin/orca/lib
3 数据库初始化
目录配置
mkdir -p /home/mingjie.gmj/databases/data/gpdata3400/master
mkdir -p /home/mingjie.gmj/databases/data/gpdata3400/segments
mkdir -p /home/mingjie.gmj/gpconfigs
*环境变量配置*
配置后，可以不用gp提供的greenplum_path.sh
配置后一定一定执行sudo ldconfig
export GPPORT=3400
export GP_DIR_PRE=/home/mingjie.gmj/databases/data
export GPHOME=$GP_DIR_PRE/gpsql$GPPORT
export GPDATA=$GP_DIR_PRE/data/gpdata$GPPORT
#export PYTHONHOME=$GPHOME/ext/python:$PYTHONHOME
export PYTHONPATH=$GPHOME/lib/python:$PYTHONPATH
export LD_LIBRARY_PATH=$GPHOME/lib:$HOME/bin/orca/lib
export PATH=$HOME/bin/cmake315/bin:$GPHOME/bin:$PATH
创建安装配置文件，记得提前配/etc/host文件，sdw1,2,3都指向127.0.0.1
cat >> hostfile_gpinitsystem << EOF
sdw1
sdw2
sdw3
EOF
cat >> gpinitsystem_config << EOF

MASTER_HOSTNAME=iZbp1d4tisi44j6vxze02fZ

EOF
初始化数据库
gpinitsystem -c gpinitsystem_config -h hostfile_gpinitsystem
安装结束！

5 总结
-
单机单用户是完全可以安装的
-
过程中尽量清空PG的环境变量，避免未知错误
-
gpAdminLogs中提供了详细的错误输出，兵来将挡：）
