禁止ntp服务
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
reboot
step 3：安装 gi
下载linuxx64_12201_grid_home.zip 上传到 nodea 的 /tmp 下
切换到grid用户，解压到grid用户下的$ORACLE_HOME
安装 cvuqdisk
# cd /u01/app/grid/
