Turn off SELinux
Vi/etc/selinux/config
Set selinux=disabled

Shutting down the firewall
Service Iptables Stop

[Email Protected]?tmp]#?yum install-y binutils compat-libstdc++-33 elfutils-libelf elfutils-libelf-devel gcc gcc-c++ glibc Glibc-common glibc-devel libaio libaio-devel libgcc libstdc++ libstdc++-devel make numactl sysstat libxp unixODBC un Ixodbc-devel

2. Add installation users and user groups
[[Email Protected]?tmp]#?groupadd Oinstall
[[Email Protected]?tmp]#?groupadd dba
[[Email protected]?tmp]#?useradd-g oinstall-g dba Oracle
[[Email protected]?tmp]#?passwd Oracle]
[[Email Protected]?tmp]#?id Oracle]
UID=1001 (Oracle) gid=1001 (oinstall) group =1001 (Oinstall), 1002 (DBA)

Create the installation directory
[Email protected] opt]# mkdir-p/opt/oracle/product/11.2.0
[Email protected] opt]# chown-r oracle:oinstall/opt/oracle
[Email protected] opt]# chmod-r 775/opt/oracle

[Email protected] opt]# mkdir/opt/orainventory
[Email protected] opt]# chown oracle:oinstall/opt/orainventory;
[Email protected] opt]# chmod-r 775/opt/orainventory;

Put the extracted Oracle database file into the Oracle file so that the Oracle account has execute permissions on/home/oracle/database and can use the following command to assign the directory to the Oracle account owner with Execute permissions

[Email protected] database]# chmod-r 700/opt/oracle/database
[Email protected] database]# chown-r oracle:oinstall/opt/oracle/database

3. Modify kernel parameter configuration file
[[Email protected]?~]#?vi/etc/sysctl.conf
Add the following content
FS.AIO-MAX-NR = 1048576
Fs.file-max = 6815744
Kernel.shmall = 2097152
Kernel.shmmax = 1073741824
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
Execute the following command for the configuration to take effect
[[email protected]?~]#?sysctl-p?]
where Kernel.shmmax = 1073741824 is the half of the native physical memory (2G), in bytes.

4. Modify the user's limit file
[[Email protected]?~]#?vi/etc/security/limits.conf
Add the following content:

Oracle Soft Nproc 2047

Oracle Hard Nproc 16384

Oracle Soft Nofile 1024

Oracle Hard Nofile 65536

Oracle Soft Stack 10240

Options available
To modify the/etc/pam.d/login file:
[[Email Protected]?~]#?vi/etc/pam.d/login
Add the following content:
Session?required?? /lib64/security/pam_limits.so
Session?required?? Pam_limits.so

5. Configure Environment variables

[[Email protected]?~]# vi/etc/profile
Add the following content:?
if [$USER = "Oracle"]; Then
? if[$SHELL = "/bin/ksh"]; Then
?? Ulimit-p 16384
?? Ulimit-n 65536
? Else
?? Ulimit-u 16384-n 65536
? Fi
Fi

?
[[Email Protected]?~]#?su-oracle
[[Email Protected]?~]$?vi/home/oracle/.bash_profile
(Note: Oracle user files are automatically generated in the home file when the user is created)
Add the following content:
Oracle_base=/opt/oracle (Installation directory)
Oracle_home= $ORACLE _base/product/11.2.0
ORACLE_SID=ORCL (the instance name is consistent with the name when the Oracle database was created)
Path= $PATH: $ORACLE _home/bin
Export Oracle_base oracle_home Oracle_sidpath

7.Oracle installation graphical interface garbled can execute the following command before performing the installation
[[Email protected] database] export lang=en_us;
