Installation of Oracle in Linux

Recently, I became the loyal fans of linus, And the linux lady was handsome. I found the feeling of Character Control. Installing linux in Oracle was a tough task, it took two days for free time. Share with you.

First of all, it is a Linux package. The gcc package and java package must be installed. Otherwise, an error will be reported !!!

1. Check the size of RAM and swap space:

Grep MemTotal/proc/meminfo

Grep SwapTotal/proc/meminfo

2. Create an Oracle group and User Account

Groupadd oinstall

Groupadd dba

Useradd-m-u 500 (others can also be)-g oinstall-G dba oracle

Id oracle

3. Modify the password of an oracle account

Passwd oracle

4. Create a directory

Mkdir-p/u01/app/oracle

Mkdir-p/archive

Chown-R oracle: oinstall/u01/archive

Chmod-R 775/u01/archive

5. modify oracle Software Directory Permissions

Mkdir-P/soft/oracle

Copy the oracle Installation File to the/soft/oracle directory, and then run the following command:

Chown-R oracle: oinstall/soft/oracle

6. Configure Linux kernel parameters (2147483648 is 2 GB)

Edit the/etc/sysctl. conf file and add the following content:

Kernel. shmall = 2097152

Kernel. shmmax = 8589934592

Kernel. shmmni = 4096

Kernel. sem = 25032000100128

Fs. file-max = 65535

Net. ipv4.ip _ local_port_range = 102465000

Net. core. rmem_default = 262144

Net. core. wmem_default = 262144

Net. core. rmem_max = 262144

Net. core. wmem_max = 262144

Run/sbin/sysctl-p to check parameters

7. To improve shell restrictions for oracle users

Edit the/etc/security/limits. conf file and add the following content:

Oracle soft nproc 2047

Hard nproc 16384

Oracle soft nofile 1024

Oracle hard nofile 65536

Edit the/etc/profile file with 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

8. Configure oracle user environment variables (Log On As an oracle user)

Run su-oracle

Edit the/home/oracle/. bash_profile file with the following content:

Export ORACLE_BASE =/u01/app/oracle

Export ORACLE_HOME = $ ORACLE_BASE/10.2.0/db_1

Export ORACLE_SID = orcl

Export PATH = $ ORACLE_HOME/bin: $ PATH

9. Install oracle

After the configuration is complete, restart the server, log on to the oracle user, open the terminal, enter the/soft/oracle/database directory, and run./runInstaller.

You should be familiar with the graphical installation.

So far, all over, hey, I hope it will help you. I love you.
