Oracle在Linux上的预配置

配置内核参数：

[root@RHEL yum.repos.d]# tail -n 10 /etc/sysctl.conf
kernel.shmall = 2097152
kernel.shmmax = 536870912
kernel.shmmni = 4096
kernel.sem = 250 32000 100 128
fs.file-max = 65536
net.ipv4.ip_local_port_range = 1024 65000
net.core.rmem_default = 4194304
net.core.rmem_max = 4194304
net.core.wmem_default = 262144
net.core.wmem_max = 262144
[root@RHEL yum.repos.d]#

LinuxPAM（插入式认证模块）pam_limits.so的配置文件：

[root@RHEL yum.repos.d]# vim /etc/security/limits.conf
[root@RHEL yum.repos.d]# tail -n 4 /etc/security/limits.conf
*        soft        nproc        2047
*        hard        nproc        16384
*        soft        nofile       1024
*        hard        nofile       65536
[root@RHEL yum.repos.d]#

Login命令的Pam模块配置文件：

[root@RHEL yum.repos.d]# vim /etc/pam.d/login
[root@RHEL yum.repos.d]# tail -n 2 /etc/pam.d/login
session        required        /lib/security/pam_limits.so
session        required        pam_limits.so
[root@RHEL yum.repos.d]#

创建用户及其组：

[root@RHEL yum.repos.d]# groupadd oinstall
[root@RHEL yum.repos.d]# groupadd dba
[root@RHEL yum.repos.d]# useradd -g oinstall -G dba oracle
[root@RHEL yum.repos.d]# echo oracle | passwd --stdin oracle
Changing password for user oracle.
passwd: all authentication tokens updated successfully.
[root@RHEL yum.repos.d]#

创建目录结构及其权限：

[root@RHEL yum.repos.d]# mkdir /single/ora10g -p
[root@RHEL yum.repos.d]# chown -R oracle.oinstall /single/
[root@RHEL yum.repos.d]# chmod -R 777 /single/
[root@RHEL yum.repos.d]#
[root@RHEL yum.repos.d]# ll -d /single/
drwxrwxrwx 3 oracle oinstall 4096 Jan  8 15:47 /single/
[root@RHEL yum.repos.d]# ll /single/
total 4
drwxrwxrwx 2 oracle oinstall 4096 Jan  8 15:47 ora10g
[root@RHEL yum.repos.d]#

Linux用户oracle的环境变量：

[root@RHEL yum.repos.d]# vim /home/oracle/.bash_profile
[root@RHEL yum.repos.d]# tail -n 10 /home/oracle/.bash_profile
export TMP=/tmp
export TMPDIR=$TMP
export ORACLE_BASE=/single/ora10g
export ORACLE_HOME=$ORACLE_BASE/product/10.2.0/db_1
export ORACLE_SID=elis10
export ORACLE_TERM=xterm
export PATH=/usr/sbin:$PATH
export PATH=$ORACLE_HOME/bin:$PATH
export LD_LIBRARY_PATH=$ORACLE_HOME/lib:/lib64:/usr/lib64:/usr/local/lib64:/usr/X11R6/lib64/
export CLASSPATH=$ORACLE_HOME/JRE:$ORACLE_HOME/jlib:$ORACLE_HOME/rdbms/jlib
[root@RHEL yum.repos.d]#
