linux下oracle11g安装

一.创建用户和组
#groupadd oinstall
#groupadd dba
#useradd -g oinstall -G dba oracle
#passwd oracle

二.配置内核
编辑/etc/sysctl.conf
fs.file-max = 512 * PROCESSES
kernel.shmall = 2097152
kernel.shmmax = 2147483648
kernel.shmmni = 4096
kernel.sem = 250 32000 100 128
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

/etc/security/limits.conf
oracle soft nproc 2047
oracle hard nproc 16384
oracle soft nofile 1024
oracle hard nofile 65536
/etc/pam.d/login
session required /lib/security/pam_limits.so
session required pam_limits.so

三.创建目录
#mkdir -p /u01/app
#chown -R oracle:oinstall /u01/app
#chmod -R 775 /u01/app
#mkdir -p /u02/oradata
#chown oracle:oinstall /u02/oradata
#chmod 775 /u02/oradata

四.设置环境变量
用oracle用户进入编辑.bash_profile
DISPLAY=local_host=0.0;
export DISPLAY
