一、将系统更新到最新，在终端执行如下代码。需要联网，且花费时间较长。
sudo apt-get update
sudo apt-get dist-upgrade
二、安装依赖包。同样需要联网，且时间较长。
sudo apt-get install alien binutils build-essential cpp-4.4 debhelper g++-4.4 gawk gcc-4.4 gcc-4.4-base gettext html2text ia32-libs intltool-debian ksh lesstif2 lib32bz2-dev lib32z1-dev libaio-dev libaio1 libbeecrypt7 libc6 libc6-dev libc6-dev-i386 libdb4.8 libelf-dev libelf1 libltdl-dev libltdl7 libmotif4 libodbcinstq4-1 libodbcinstq4-1:i386 libqt4-core libqt4-gui libsqlite3-0 libstdc++5 libstdc++6 libstdc++6-4.4-dev lsb lsb-core lsb-cxx lsb-desktop lsb-graphics lsb-qt4 make odbcinst pax po-debconf rpm rpm-common sysstat unixodbc unixodbc-dev unzip
三、创建用户、用户组（可选，用当前wwr用户也可，但我安装时候新建了一个oracle用户）
sudo groupadd oinstall
sudo groupadd dba
sudo mkdir -p /opt/oracle
sudo useradd -g oinstall -G dba -d /opt/oracle -s /bin/bash oracle
sudo passwd oracle
sudo chown -R oracle:oinstall /opt/oracle
sudo groupadd oinstall
sudo groupadd dba
sudo mkdir -p /opt/oracle
sudo useradd -g oinstall -G dba -d /opt/oracle -s /bin/bash oracle
sudo passwd oracle
sudo chown -R oracle:oinstall /opt/oracle
sudo groupadd oinstall
sudo groupadd dba
sudo mkdir -p /opt/oracle
sudo useradd -g oinstall -G dba -d /opt/oracle -s /bin/bash oracle
sudo passwd oracle
sudo chown -R oracle:oinstall /opt/oracle
四、检查系统变量
/sbin/sysctl -a | grep sem
/sbin/sysctl -a | grep shm
/sbin/sysctl -a | grep file-max
/sbin/sysctl -a | grep aio-max
/sbin/sysctl -a | grep ip_local_port_range
/sbin/sysctl -a | grep rmem_default
/sbin/sysctl -a | grep rmem_max
/sbin/sysctl -a | grep wmem_default
/sbin/sysctl -a | grep wmem_max
然后根据结果在/etc/sysctl.conf中增加对应数据
fs.aio-max-nr = 1048576
fs.file-max = 6815744
kernel.shmall = 2097152
kernel.shmmax = 536870912
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 = 1048586
执行以下命令更新内核参数
sudo sysctl -p
