Installation：

1. 修改sysctl.conf文件，在文件末尾插入

Edit sysctl.conf file，at the end of file add in

vi /etc/sysctl.conf

fs.aio-max-nr = 1048576

fs.file-max = 6815744

kernel.shmmni = 4096

kernel.sem = 250 32000 100 128

net.ipv4.ip_local_port_range = 9000 65500

net.core.rmem_default = 262144

net.core.rmem_max = 4194304

net.core.wmem_default = 262144

2. 执行sysctl –p，确保输出结果与第一步的数据相同

Enter sysctl –p, make sure the output is the same as step 1

3. 修改limits.conf，在文件末尾插入

Edit limits.conf file，at the end of file add in

vi /etc/security/limits.conf

oracle soft nproc 2047

oracle hard nproc 16384

oracle soft nofile 1024

oracle hard nofile 65536

oracle hard stack 10241

4. 关闭selinux，把enforcing 改为disabled

Turn off selinux, change enforcing to disabled

vi /etc/sysconfig/selinux

selinux=disabled

groupadd oinstall

groupadd oper

useradd oracle 创建oracle用户

/usr/sbin/useradd -g oinstall -G dba,oper oracle

usermod -g dba oracle 把oracle用户加到dba组里

passwd oracle 给oracle用户建密码

10. 给oracle建安装目录

Create install dirctory for oracle

mkdir -p /u01/app/oracle

chown -R oracle:dba /u01/app/oracle 把文件属主改为oracle

chmod -R 777 /u01/app/oracle 把文件权限改为777

11. 配置oracle用户环境变量（home、base、sid、path、umask）
