12c install on centos 6.5_64 4G内存

1.修改/etc/hosts
192.168.5.100 source

2.修改内核参数 vi /etc/sysctl.conf
fs.file-max = 6815744
kernel.sem = 250 32000 100 128
kernel.shmmni = 4096
kernel.shmall = 2147483648 --内存一半
kernel.shmmax = 4398046511104
net.core.rmem_default = 262144
net.core.rmem_max = 4194304
net.core.wmem_default = 262144
net.core.wmem_max = 1048576
fs.aio-max-nr = 1048576
net.ipv4.ip_local_port_range = 9000 65500
# sysctl -p

3.增加oracle系统限制条目 vi /etc/security/limits.conf
oracle soft nofile 1024
oracle hard nofile 65536
oracle soft nproc 2047
oracle hard nproc 16384
oracle soft stack 10240
oracle hard stack 32768

4.创建系统用户及组
# groupadd -g 54321 oinstall
# groupadd -g 54322 dba
# groupadd -g 54323 oper
# useradd -u 54321 -g oinstall -G dba,oper oracle
# passwd oracle

5.修改/etc/security/limits.d/90-nproc.conf
#* soft nproc 1024
root soft nproc unlimited
* - nproc 16384

6.关闭selinux和iptable

7.创建安装目录 并添加环境变量
# mkdir -p /u01/app/oracle/product/12.1.0/db_1
# chown -R oracle:oinstall /u01
# chmod -R 775 /u01
# vi /home/oracle/.bash_profile
export TMP=/tmp
export TMPDIR=$TMP
export ORACLE_HOSTNAME=source
export ORACLE_UNQNAME=cdb1
export ORACLE_BASE=/u01/app/oracle
export ORACLE_HOME=$ORACLE_BASE/product/12.1.0/db_1
export ORACLE_SID=cdb1
export PATH=/usr/sbin:$PATH
export PATH=$ORACLE_HOME/bin:$PATH
export LD_LIBRARY_PATH=$ORACLE_HOME/lib:/lib:/usr/lib
export CLASSPATH=$ORACLE_HOME/jlib:$ORACLE_HOME/rdbms/jlib

9.解压安装包执行安装

[root@source tmp]# unzip linuxamd64_12c_database_1of2.zip

[root@source tmp]# unzip linuxamd64_12c_database_2of2.zip

[root@source tmp]# chown -R oracle:oinstall database

[root@source database]# ./runInstaller

10.报错INS-13001错误 直接跳过，但是用oracle linux不会报此错误。
