修改selinux/config内的文件
vi /etc/selinux/config
# This file controls the state of SELinux on the system.
# SELINUX= can take one of these three values:
# enforcing - SELinux security policy is enforced.
# permissive - SELinux prints warnings instead of enforcing.
# disabled - No SELinux policy is loaded.
SELINUX=disabled
# SELINUXTYPE= can take one of these two values:
# targeted - Targeted processes are protected,
# mls - Multi Level Security protection.
SELINUXTYPE=targeted
创建用户和组
groupadd -g 2000 oinstall
groupadd -g 2200 asmadmin
groupadd -g 2201 asmdba
groupadd -g 2202 asmoper
groupadd -g 2300 dba
groupadd -g 2301 oper
useradd -m -u 1100 -g oinstall -G asmadmin,asmdba,asmoper,dba -d /home/grid -s /bin/bash -c "Grid Infrastructure Owner" grid
useradd -m -u 1101 -g oinstall -G dba,oper,asmdba -d /home/Oracle -s /bin/bash -c "Oracle Software Owner" oracle
passwd grid

chown oracle:oinstall /opt/ora11g/oracle
chmod -R 775 /opt
切换到oracle用户
修改环境变量
注意在配置环境变量时，两个节点的oracle_sid是不同的，要记得修改
