CentOS 默认不在 Oracle 官方支持的操作系统之列。 ACFS 这个特性在安装 Grid 时也没有安装。尝试安装时，会提示 ”Not Supported”
安装 Oracle Enterprise Linux 的内核
参考： http://linuxsysconfig.com/2015/02/centos-7-with-oracle-uek3/
上传一个 OEL 7.3 的 ISO 文件
用 ISO 做一个本地 yum 源
安装
yum-config-manager --disable ol7* yum-config-manager --enable ol7_UEKR3 sed -i 's/DEFAULTKERNEL=kernel/DEFAULTKERNEL=kernel=uek/' /etc/sysconfig/kernel yum install kernel-uek kernel-uek-devel 安装之后： grub2-editenv list init 6
打 GRID 软件补丁
补丁： 25078431
1. 替换掉 opatch 工具
p6880880_180000_Linux-x86-64.zip 这里所有节点的 opatch 都要替换
2. 解压补丁包
unzip /u01/p25078431_122010_Linux-x86-64.zip -d /tmp
3. 打补丁
/u01/app/12.2.0/grid/OPatch/opatchauto apply /tmp/25078431 两个节点都要打
4. 修改 Oracle 配置文件
修改 $GRID_HOME/lib/ osds_acfslib.pm 参考： https://blog.csdn.net/weiwangsisoftstone/article/details/78813518 [root@rac01 lib]# vi osds_acfslib.pm # Testing for "oraclelinux_release", etc prevents us from dropping # into the code below from other RH based distros like CentOS, for example. if ((defined($release)) && # Redhat or OEL if defined (($release =~ /^redhat-release/) || # straight RH ($release =~ /^enterprise-release/) || # Oracle Enterprise Linux ($release =~ /^centos-release/) || # CentOS hack ($release =~ /^oraclelinux-release/))) # Oracle Linux
