1 preparation before installation

Yum-y install binutils compat-libcap1 compat-libstdc++.i686 compat-libstdc++.x86_64 elfutils-libelf elfutils-libelf-devel gcc gcc-c++ glibc.i686 glibc.x86_64 glibc-devel.i686 glibc-devel.x86_64 ksh libgcc.i686 libgcc.x86_64 libstdc++.i686 libstdc++.x86_64 libstdc++-devel.i686 libstdc++-devel.x86_64 libaio.i686 libaio.x86_64 libaio-devel.i686 libaio-devel.x86_64 libXext libXtst libX11 libXau libxcb libXi make sysstat unixODBC-devel.i686 unixODBC-devel.x86_ 64 unixODBC.i686 unixODBC.x86_64 compat-libstdc++-33.i686 compat-libstdc++-33.x86_64

Close selinux and firewalld

2 set host resolution: host name oracle

10.0.0.2 oracle

3 create groups and users

Groupadd oinstall

Groupadd dba

Useradd-g oinstall-G dba oracle / usermod-g oinstall-G dba oracle (there is a command to renew the account)

Passwd oracle

4 modify kernel parameters

Vi / etc/sysctl.d/sysctl.conf

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 = 1048576

Sysctl-p

5 configuration of system resource restrictions

Vi / etc/security/limits.conf

Oracle soft nproc 2047

Oracle hard nproc 16384

Oracle soft nofile 1024

Oracle hard nofile 65536

Oracle soft stack 10240

6 create a database folder to assign group permissions

Mkdir-p / u01/app/

Mkdir-p / u01/app/oracle/product/12.1.0/dbhome_1

Chown-R oracle:oinstall / u01/app/

Chmod-R 775 / u01/app/

7 set environment variables

ORACLE_BASE=/u01/app

ORACLE_HOME=$ORACLE_BASE/oracle/product/12.1.0/dbhome_1

ORACLE_SID=orcl

LD_LIBRARY_PATH=$ORACLE_HOME/lib

PATH=$PATH:$ORACLE_HOME/bin:$HOME/bin

Export ORACLE_BASE ORACLE_HOME ORACLE_SID LD_LIBRARY_PATH PATH

8 set the DISPLAY variable (avoid errors in vnc connection installation)

Export DISPLAY=:1

Next, follow the custom installation through the vnc graphical interface, without any error prompt.

After installation:

Check to see if you are listening:

[oracle@oracle ~] $ps-ef | grep LISTENER

Oracle 9976 1 0 Jul13? 00:00:00 / u01/app/oracle/product/12.1.0/dbhome_1/bin/tnslsnr LISTENER-inherit

There was an error restarting the database dbshut:

ORACLE_HOME_LISTNER is not SET, unable to auto-stop Oracle Net Listener Usag

The corresponding script file will be changed to:

Change ORACLE_HOME_LISTNER=$1 to ORACLE_HOME_LISTNER=$ORACLE_HOME
