RHEL 6.2 x86_64 下安装Oracle 11g步骤,

在安装过程中如遇到问题可以一起讨论,,共同学习,如有错误,还请告知,谢谢

1.首先 修改 /etc/sysctl.conf文件 添加参数

[root@redz-server ~]# cat >>/etc/sysctl.conf

> #Oracle need parameters

> fs.aio-max-nr=1048576

> fs.file-max=6815744

> kernel.shmall=2097152

> kernel.shmmax=1024000000(根据系统内存多少来调整)

> kernel.shmmni=4096

> kernel.sem=250 32000 100 65500

> net.ipv4.ip_local_port_range=9000 65500

> net.core.rmen_default=262144

> net.core.rmem_max=4194304

> net.core.wmem_default=262144

> net.core.wmem_max=1048586

> EOF

 

执行  /sbin/sysctl -p使参数生效

 

2. 修改 /etc/security/limits.conf

[root@redz-server ~]# cat >>/etc/sysctl.conf

[root@redz-server ~]# cat >> /etc/security/limits.conf

> # oracle need parameters

> orcle  soft  nproc    2047

> oracle  hard  nproc   16384

> oracle  soft  nofile  1024

> oracle  hard  nofile  65536

> EOF

 

3. 修改 /etc/pam.d/limits.conf

[root@redz-server ~]# cat >> /etc/pam.d/login

> session  required  pam_limits.so

> EOF

4.修改 /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

4. 修改 /etc/csh.login

 vi /etc/csh.login

 

#oracle need setting

if ( $USER == "oralce" ) then

   limit maxproc        16384

   limit descriptors    65536

   umask 022

endif

 

5.创建用户组及用户

[root@redz-server ~]# /usr/sbin/groupadd oinstall

[root@redz-server ~]# /usr/sbin/groupadd dba

[root@redz-server ~]# /usr/sbin/useradd -m -g oinstall -G dba oracle

[root@redz-server ~]# echo "oracle"|passwd --stdin oracle

 

更改用户 oracle 的密码 。

passwd: 所有的身份验证令牌已经成功更新。
