RHEL6 安装 Oracle11g

1. 编辑 hosts 文件：/etc/hosts

# hostname loopback address
ip_address    hostname

2. 挂载操作系统光盘

mkdir /mnt/cdrom
mount /dev/cdrom /mnt/cdrom

如果是 ISO 文件，可采用如下方式挂载：
mount -o loop redhat6.iso /mnt/cdrom

3. 编辑 /etc/yum.repo.d/rhel-source.repo 文件，配置本地 YUM 源

[local-yum]
name=RHEL6 ISO
baseurl=file:///mnt/cdrom/Server
enabled=1
gpgcheck=0

4. 更新本地 YUM 缓存

yum clean all && yum makecache

5. 安装 oracle 所需的依赖包 yum install ...

6. 编辑 /etc/security/limits.conf，修改限制 oracle 用户的资源使用

oracle soft nproc 2047
oracle hard nproc 16384
oracle soft nofile 1024
oracle hard nofile 65536
oracle soft stack 10240

7. 编辑 /etc/sysctl.conf，修改 Linux 内核参数

fs.aio-max-nr = 1048576
fs.file-max = 6815744
kernel.shmall = 2097152
kernel.shmmax = 4294967295
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
net.core.wmem_max = 1048576

8. 使修改的参数生效

sysctl -p

9. 创建安装需要的用户和组

groupadd dba && groupadd oinstall && useradd –g dba –G oinstall oracle && passwd oracle

10. 创建软件安装目录并授权给 oracle 用户

mkdir –p /u01/app/oracle && chown –R oracle:oinstall /u01 && chmod –R 775 /u01

11. 编辑 /home/oracle/.bash_profile，配置 oracle 用户的环境变量

export ORACLE_SID=orcl
export ORACLE_BASE=/u01/app/oracle
export ORACLE_HOME=$ORACLE_BASE/product/11.2.0/db_1
export PATH=$ORACLE_HOME/bin:$PATH

12. 使用 oracle 用户开始安装
