5, Machine name hostname

Please change the hostname in the/etc/sysconfig/network to match the/etc/hosts

6, modify the kernel parameters (operating under the root account): Edit the kernel parameter profile vi/etc/sysctl.conf, modify or add the following line under the file:

Fs.file-max = 6815744
fs.aio-max-nr=1048576
Kernel.shmall = 2097152
Kernel.shmmax = 2147483648
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

Then execute the following command to make the above configuration effective immediately:

Sysctl-p;
7. Modify the system resource limit (operate under root account):

Edit the system resource limit profile vi/etc/security/limits.conf, and add the following line under the file:

Oracle Soft Nproc 2047oracle hard nproc 16384oracle soft nofile 1024oracle hard nofile 65536oracle soft stack 10240

8. Create users and Groups

Groupadd Oinstall;groupadd Dba;groupadd Oper;

USERADD-G oinstall-g Dba,oper Oracle; #初始群组为 Oinstall, the effective group is DBA, OPERPASSWD Oracle; #为oracle帐号设置密码 (login required during installation)
If an Oracle account already exists, use the command usermod-a-G Dba,oper Oracle to join the group DBA and Oper

8, set up the installation directory
Mkdir-p/u01/app/oracle/product/11.2.0/db_1
Chown-r Oracle:oinstall/u01/app
Chmod-r 775/u01/app

VI ~oracle/.bash_profile

Oracle_home= $ORACLE _base/product/11.2.0/db_1
Oracle_sid=orcl
Export Oracle_base oracle_home Oracle_sid

Path= $ORACLE _home/bin: $PATH
Export PATH

10. Start the installation

Download Oracle files for SSH to/u01/app/oracle

# su-oracle
$ cd/u01/app/oracle
$ unzip Linux.x64_11gR2_database_1of2.zip
$ unzip Linux.x64_11gR2_database_2of2.zip
