创建组和用户
# /usr/sbin/groupadd oinstall
# /usr/sbin/groupadd dba
# /usr/sbin/groupadd oper
# /usr/sbin/useradd -g oinstall -G dba,oper oracle
配置内核参数和资源限制
编辑/etc/sysctl.conf在最后加入
fs.aio-max-nr = 1048576
fs.file-max = 6815744
kernel.shmall = 2097152
kernel.shmmax = 536870912
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 = 1048586
保存后检查
# /sbin/sysctl -p
设置安装软件用户的资源限制
/etc/security/limits.conf
oracle soft nproc 2047
oracle hard nproc 16384
oracle soft nofile 1024
oracle hard nofile 65536
oracle soft stack 10240

创建目录
# mkdir -p /u01/app/
# chown -R oracle:oinstall /u01/app/
# chmod -R 775 /u01/app/
设置DISPLAY环境变量
本机安装
#export DISPLAY=:0.0
远程安装
#export DISPLAY=目标服务器ip:0.0
解压oracle 12c安装包
Unzip linuxamd64_12102_database_1of2.zip
Unzip linuxamd64_12102_database_2of2.zip
解压结束会看到database文件夹
切换到ORACLE用下
./runInstaller
安装完毕后根据安装目录设置环境变量
Su – root
Vim /etc/profile
TMP=/tmp; export TMP
TMPDIR=$TMP; export TMPDIR
ORACLE_BASE=/u01/app; export ORACLE_BASE
ORACLE_HOME=$DB_HOME; export ORACLE_HOME
ORACLE_SID=db_sid; export ORACLE_SID
ORACLE_TERM=xterm; export ORACLE_TERM
BASE_PATH=/usr/sbin:$PATH; export BASE_PATH
PATH=$ORACLE_HOME/bin:$BASE_PATH; export PATH
LD_LIBRARY_PATH=$ORACLE_HOME/lib:/lib:/usr/lib; export LD_LIBRARY_PATH
CLASSPATH=$ORACLE_HOME/JRE:$ORACLE_HOME/jlib:$ORACLE_HOME/rdbms/jlib; export CLASSPATH
验证ORACLE安装成功
