GaussDB(DWS)8.0.0.0版本集群安装

2.vi /etc/hosts 
192.168.0.155 node1 node1.com

3.修改OS参数：
vi /etc/sysctl.conf
vm.min_free_kbytes = (free -k|grep Mem|awk ‘{print $2}’)*5%

4.安装依赖包：（防止缺包情况）
yum install -y OpenIPMI openldap \
openldap-clients openldap-servers perl-Perlilog procmail python-dateutil \
python-dmidecode python-gudev python-simplejson pytz \
sdparm

5.检查OS编码格式是否为en_US.UTF-8
否的话，需要修改vim /etc/locale.conf 然后reboot

cp FusionInsight_BASE_6.5.1_RHEL.tar.gz GaussDB_200_6.5.1_RHEL.tar.gz FusionInsight_Manager/software/packs/

6.cd /opt/FusionInsight_SetupTool/preset （准备静默补丁软件包）
sh preset.sh

7.编辑preinstall文件

vi /opt/FusionInsight_SetupTool/preinstall/preinstall.ini
g_hosts="192.168.0.155"
g_user_name="root"
g_port=22
g_parted=2
g_parted_conf="192.168.0.155:host0.ini;"
g_add_pkg=1
g_pkgs_dir="centos-7.6:/media/"
g_log_file="/tmp/fi-preinstall.log"
g_debug=0
g_hostname_conf="192.168.0.155#192.168.0.155#host1"
g_swap_off=1
g_platform="x86_64"

8.分区配置文件

cd /opt/FusionInsight_SetupTool/preinstall/partition/ini/
vi host0.ini
#mount required care condition
dbdata_om.conf y y n
#backup_om.conf y y n
mppdb1.conf y y n
#mppdb2.conf y y n

9.进入preinstall执行目录，并执行preinstall脚本

cd /opt/FusionInsight_SetupTool
./setuptool.sh preinstall -n

10.Manager安装配置文件

cd /opt/FusionInsight_Manager/software
vi install.ini

cd /opt/FusionInsight_Manager/software

11.执行单机版配置脚本

切换至OMM用户
su - omm
执行单机实例配置脚本 重启controller
sh ${BIGDATA_HOME}/om-server/om/sbin/enable_single_host_cluster.sh
sh ${BIGDATA_HOME}/om-server/om/sbin/restart-controller.sh

第一步会提示修改密码，请按步骤操作

cat /opt/FusionInsight_SetupTool/preinstall/partition/ini-plugin/conf/mppdb1.conf
dir=/srv/BigData/mppdb/data1

rpm -Uvh   zlib-devel-1.2.7-18.el7.x86_64.rpm  --nodeps --force

一般位于3.7以上版本编译安装时出错
缺少依赖包libffi-devel
解决方法：
yum install libffi-devel -y
