虛擬環境：vCenter
OS： redhat 7.4
RDBMS：12.1.0.2.0
關閉防火牆,不然在安裝GI的時候，會提示各個節點之間網路不通，雖然可以ping通
systemctl stop firewalld
chkconfig firewalld off /etc/hosts 設定

ntp設定，其實不設定也可以
[[email protected] etc]# mv ntp.conf ntp.conf_bak安裝需要的軟體包
binutils compat-libcap1 compat-libstdc++-33 -- 比較奇怪，這個包redhat7.4光盤裡面沒有的，用redhat6.9安裝的 gcc gcc-c++ glibc glibc-devel ksh libgcc libstdc++ libstdc++-devel libaio libaio-devel libXext libXtst libX11 libXau libxcb libXi make sysstat libXmu libXt libXv libXxf86dgak libXxf86misc libXxf86vm xorg-x11-utils xorg-x11-xauth nfs-utils
配置yum源（略，看本人blog中的文件），並安裝軟體包，把上面的包，編輯到txt檔案中，安裝。

yum install `awk '{print $1}' /tmp/req-rpm.txt`OS配置
