2. Root users, create Oracle users and groups

Groupadd oinstall

Groupadd dba

Groupadd oper

Useradd-g oinstall-G dba,oper oracle

Passwd oracle

3. Root user, create installation directory

Mkdir-p / u01/app/oracle/product/12.2.01/db_1

Chown-R oracle:oinstall / u01/app

Chmod-R 775 / u01/app

4. Root user, modify the kernel parameter vi / etc/sysctl.conf

Fs.aio-max-nr = 1048576

Fs.file-max = 6815744

Kernel.shmall = 7549747 # kernel.shmmax/1024/4

Kernel.shmmax = 30923764531 # physical memory 32 "1024" 1024 "1024" 0.9

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

Take effect

Sysctl-p

5. For root users, change the file limit: 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

Oracle hard stack 32768

6. Root user, modify the login parameter vi / etc/pam.d/login

Session required pam_limits.so

7. Root user, modify ulimit vi / etc/profile

If [$USER = "oracle"]; then

If [$SHELL = "/ bin/ksh"]; then

Ulimit-p 16384

Ulimit-n 65536

Else

Ulimit-u 16384-n 65536

Fi

Fi

8. Root user, modify the environment variable. Vi / .bash_profile

Export JAVA_HOME=/home/soft/jdk1.8.0_65

Export JRE_HOME=$JAVA_HOME/jre

Export PATH=$PATH:$JAVA_HOME/bin:$JRE_HOME/bin

Export CLASSPATH=.:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar:$JRE_HOME/lib

9. Root user, modify the environment variable. Vi ~ oracle/.bash_profile

Export ORACLE_BASE=/u01/app/oracle

Export ORACLE_HOME=$ORACLE_BASE/product/12.2.01/db_1

Export ORACLE_SID=ORACLE

Export PATH=$ORACLE_HOME/bin:$PATH

Export DISPLAY=192.168.0.99:0.0

10. Root user, install JDK

Delete open jdk

Yum remove * openjdk*

Mkdir / home/soft/

Cd / home/soft/

Rz

Ls

Tar-zxvf jdk-8u65-linux-x64.tar.gz

Rm-rf jdk-8u65-linux-x64.tar.gz

Reboot

Java-version

11. Oracle users, upload the installation software and decompression of oralce

Su-oracle

Cd / u01/app/oracle/

Rz

Unzip linuxx64_12201_database.zip

Rm-rf linuxx64_12201_database.zip
