debian7安装oracle 11g笔记。

u盘安装debian 7.0 wheezy
debian 7.0 wheezy 发布!
1,安装必须包
apt-get install gcc g++  make binutils libc6 libc6-dev libstdc++6 libstdc++5 rpm gawk alien ksh  lesstif2 libaio1 linux-headers elfutils libaio-dev sysstat unixodbc-bin unixodbc-dev pdksh
其中还缺少java包，去官方下来安装就ok了。
2,添加用户和组
groupadd oinstall
groupadd dba
useradd oracle -m -d /home/oracle -g oinstall -g dba -s /bin/bash
passwd oracle
3,检查安装环境，此处直接写成了一个小脚本
echo sem: ;echo min 250 32000 100 128; echo is `cat /proc/sys/kernel/sem`; echo; \
echo shmall: ;echo min 2097152; echo is `cat /proc/sys/kernel/shmall`; echo; \
echo shmmax - should be able to hold the sga - max 4g-1byte: ;echo is `cat /proc/sys/kernel/shmmax`; echo; \
echo shmmni: ;echo min 4096; echo is `cat /proc/sys/kernel/shmmni`; echo; \
echo file-max: ;echo min 6815744; echo is `cat /proc/sys/fs/file-max`; echo; \
echo ip_local_port_range: ;echo min/max 9000  65500; echo is    `cat /proc/sys/net/ipv4/ip_local_port_range`; echo; \
echo rmem_default: ;echo min 262144; echo is `cat /proc/sys/net/core/rmem_default`; echo; \
echo rmem_max: ;echo min 4194304; echo is `cat /proc/sys/net/core/rmem_max`; echo; \
echo wmem_default: ;echo min 262144; echo is `cat /proc/sys/net/core/wmem_default`; echo; \
echo wmem_max: ;echo min 1048576; echo is `cat /proc/sys/net/core/wmem_max`; echo; \
echo aio-max-nr: ;echo max 1048576; echo is `cat /proc/sys/fs/aio-max-nr`; echo;
4,检查必须的参数
echo kernel.sem = 250 32000 100 128 >> /etc/sysctl.conf
echo kernel.shmall = 2097152 >> /etc/sysctl.conf
# !!!! needs to fit your sga (=main memory for database, be sure to have enough ram for pga etc.)!!!!
echo kernel.shmmax = 1200000000 >> /etc/sysctl.conf
#echo kernel.shmmni = 4096 >> /etc/sysctl.conf
echo fs.file-max = 6815744 >> /etc/sysctl.conf
#echo net.ipv4.ip_local_port_range = 1024 65000 >> /etc/sysctl.conf
echo net.core.rmem_default = 262144 >> /etc/sysctl.conf
echo net.core.rmem_default = 262144 >> /etc/sysctl.conf
echo net.core.rmem_max = 4194304 >> /etc/sysctl.conf
echo net.core.wmem_default = 262144 >> /etc/sysctl.conf
echo net.core.wmem_max = 1048576 >> /etc/sysctl.conf
echo fs.aio-max-nr = 1048576 >> /etc/sysctl.conf
5,设置limit
echo oracle soft nproc 2047 >> /etc/security/limits.conf
echo oracle hard nproc 16384 >> /etc/security/limits.conf
echo oracle soft nofile 1024 >> /etc/security/limits.conf
echo oracle hard nofile 65536 >> /etc/security/limits.conf
echo oracle soft stack 10240 >> /etc/security/limits.conf
6,建立安装目录，我的/datadisk空间最大，就放到这里面了
mkdir -p /datadisk/u01/app/oracle
mkdir -p /datadisk/u01/oradata
mkdir -p /datadisk/u01/flash_recovery_area
chown -r oracle:oinstall /datadisk/u01
chmod -r 775 /datadisk/u01/
防止出错，添加如下链接目录
ln -s /usr/bin/awk /bin/awk
ln -s /usr/bin/basename /bin/basename
7,设置display变量来显示gui安装
切换到你当前桌面登录的用户执行：xhost + ，此命令的意思是允许其它用户使用当前的桌面环境
切换回oracle用户，export display=:0 (debian7下是这样设置的)，然后执行 xclock 看看效果
8，，进行安装
./datadisk/oracle11g/database/runinstaller
9,安装过程中遇到一些问题
基本上都是一些链接的问题，用ln -s /usr/lib/xxxx.so  /lib64下基本上就ok了。看错误日志解决！
