本次實(shí)驗(yàn)涉及三個(gè)節(jié)點(diǎn)，即是管理節(jié)點(diǎn) 又是數(shù)據(jù)節(jié)點(diǎn)

數(shù)據(jù)庫(kù)版本?GBase8a 8.6.2

操作系統(tǒng)版本?CentOS Linux release 7.9.2009 (Core)

驗(yàn)證開(kāi)啟ssh【所有節(jié)點(diǎn)】

[root@localhost ~]# service sshd status

關(guān)閉selinux【所有節(jié)點(diǎn)】

[root@localhost ~]# vi /etc/selinux/config [root@localhost ~]# reboot [root@localhost ~]# sestatus

SELINUX=disabled

關(guān)閉防火墻【所有節(jié)點(diǎn)】

[root@localhost ~]# systemctl stop firewalld.service [root@localhost ~]# systemctl status firewalld.service

安裝解壓軟件【所有節(jié)點(diǎn)】

[root@localhost opt]# yum -y install bzip2.x86_64

解壓【在一個(gè)管理節(jié)點(diǎn)執(zhí)行即可】

[root@localhost ~]# cd /opt/ [root@localhost opt]# ls GBase8a_MPP_Cluster-NoLicense-8.6.2_build43-R33-132743-redhat7-x86_64.tar.bz2 [root@localhost opt]# tar xfj GBase8a_MPP_Cluster-NoLicense-8.6.2_build43-R33-132743-redhat7-x86_64.tar.bz2

配置集群信息

[root@localhost gcinstall]# vi demo.options

installPrefix= /opt
coordinateHost = 192.168.61.132,192.168.61.133,192.168.61.134
coordinateHostNodeID = 132,133,134
dataHost = 192.168.61.132,192.168.61.133,192.168.61.134
#existCoordinateHost =
#existDataHost =
loginUser= root
loginUserPwd = '111111'
#loginUserPwdFile = loginUserPwd.json
dbaUser = gbase
dbaGroup = gbase
dbaPwd = 'gbase'
rootPwd = '111111'
#rootPwdFile = rootPwd.json
dbRootPwd = ''
#mcastAddr = 226.94.1.39
mcastPort = 5493

安裝

[root@localhost gcinstall]# ./gcinstall.py --slient=demo.options
