systemctl stop chronyd
systemctl disable chronyd
systemctl stop ntpd.service
systemctl disable ntpd.service
systemctl stop ntpdate.service
systemctl disable ntpdate.service
mv /etc/chrony.conf /etc/chrony.conf.bak
mv /etc/ntp.conf /etc/ntp.conf.bak禁止avahi-daemon服务
avahi-daemon 服务会影响 oracle的多波通信，进而导致节点重启
因此，oracle环境下不能启用 avahi-daemon 服务
systemctl stop avahi-daemon.service
systemctl disable avahi-daemon.service禁用其它一些服务
systemctl disable iptables.service
systemctl disable firewalld.service
systemctl disable cups.service
systemctl disable ip6tables.service
systemctl disable firstboot-graphical.service
systemctl disable postfix.service
systemctl disable NetworkManager.service
最后确保以下服务正常
systemctl enable crond.service
systemctl enable sshd.service
systemctl enable sysstat.service
systemctl enable network.service重启os
rebootstep 2：安装 gi
下载linuxx64_12201_grid_home.zip
解压到grid用户下的$ORACLE_HOME
然后运行 gridSetup.sh
step 3：安装 db
下载 linuxx64_12201_database.zip 解压后安装
然后用 dbca 创建数据库，比较简单，过程省略
