oracle linux7安装oracle11g0204
1、平时需要修改 /etc/redhat-release文件为Red Hat Enterprise Linux 7，这次不需要了。
2、关闭selinx nano /etc/selinux/config
改为disabled
3、nano /etc/hosts 修改解析
在oracle服务器中增加 /etc/hosts中一个对应
192.168.1.10 CLOUD-MC-SQL1
4、修改系统文件 /etc/security/limits.conf ，增加
oracle soft nproc 2047
oracle hard nproc 16384
oracle soft nofile 1024
oracle hard nofile 65536
oracle soft stack 10240
5、修改内核参数/etc/sysctl.conf
net.ipv4.ip_local_port_range= 9000 65500
fs.file-max = 6815744
kernel.shmall = 10523004
kernel.shmmax = 6465333657
kernel.shmmni = 4096
kernel.sem = 250 32000 100128
net.core.rmem_default=262144
net.core.wmem_default=262144
net.core.rmem_max=4194304
net.core.wmem_max=1048576
fs.aio-max-nr = 1048576
6、安装依赖包
yum -y install binutils compat-libcap1 compat-libstdc+±33 compat-libstdc+±33*.i686 elfutils-libelf-devel gcc gcc-c++ glibc*.i686 glibc glibc-devel glibc-devel*.i686 ksh libgcc*.i686 libgcc libstdc++ libstdc++.i686 libstdc+±devel libstdc+±devel.i686 libaio libaio*.i686 libaio-devel libaio-devel*.i686 make sysstat unixODBC unixODBC*.i686 unixODBC-devel unixODBC-devel*.i686 libXp
7、建立用户及目录
groupadd oinstall
groupadd dba
groupadd oper
useradd -g oinstall -G dba,oper oracle
echo ‘oracle’ | passwd --stdin oracle
usermod -a -G oinstall,dba,oper or
