oraclelinux7-oracle12c部署
/mnt/dbinstall 安装目录
/mnt/dbapp 程序目录
/mnt/dbdata 数据目录
一、关闭防火墙
systemctl stop firewalld.service
systemctl disable firewalld.service
二、关闭SELINUX
vi /etc/selinux/config
#SELINUX=enforcing #注释掉
#SELINUXTYPE=targeted #注释掉
SELINUX=disabled #增加
:wq #保存，关闭。
sestatus -v
三、查看系统信息
grep SwapTotal /proc/meminfo 查看内存和交换空间
uname -m 查询系统位数
cat /proc/version或# cat /etc/redhat-release或# lsb_release -id 查询系统版本
uname -r 系统内核
四、Oracle12c
1、rpm -q binutils compat-libcap1 compat-libstdc+±33 gcc gcc-c++ glibc glibc-devel ksh libaio libaio-devel libgcc libstdc++ libstdc+±devel libXext libXtst libX11 libXau libxcb libXi make sysstat
2、yum install binutils compat-libcap1 compat-libstdc+±33 gcc gcc-c++ glibc glibc-devel ksh libaio libaio-devel libgcc libstdc++ libstdc+±devel libXext libXtst libX11 libXau libxcb libXi make sysstat
3、groupadd oinstall
4、groupadd dba
5、useradd -g oinstall -G dba oracle
6、passwd oracle
7、chown -R oracle:oinstall /mnt/
8、chmod -R 775 /mnt/
9、vi /etc/sysctl.conf 加入

10、sysctl -p
11、vi /etc/security/limits.conf 加入

12、# su - oracle
$vi .bash_profile 加入

$ source .bash_profile
13./mnt/dbinstall/runInstall.sh
14.按照提示安装，中途需切换root用户执行sh
15.启动问题
cd /mnt/dbapp/admin/orcl/pfile/
cp init.ora.XXX /mnt/dbapp/product/12.1.0/db_1/dbs/
mv init.ora.XXX initORCL.ora
cp initORCL.ora initorcl.ora
16.乱码
vi /etc/profile 在文件最后添加
export NLS_LANG=AMERICAN_AMERICA.ZHS16GBK
17.启动
vi /etc/oratab
orcl:/mnt/orcl/oracle/product/12.1.0/dbhome_1:N”，改为“orcl:/mnt/orcl/oracle/product/12.1.0/dbhome_1:Y”
在/etc/rc.d/rc.local中加入如下语句即可实现同系统启动实例：
su - oracle -c “lsnrctl start”
su - oracle -c “dbstart”
