Linux安装Oracle 12C
1.1.1. 系统配置
配置host ：vi /etc/hosts
ip 主机名
192.168.0.129 yang
安装oracle依赖包关系
yum install -y binutils compat-libcap1 compat-libstdc+±33 compat-libstdc+±33.i686 glibc glibc.i686 glibc-devel glibc-devel.i686 ksh libaio libaio.i686 libaio-devel libaio-devel.i686 libX11 libX11.i686 libXau libXau.i686 libXi libXi.i686 libXtst libXtst.i686 libgcc libgcc.i686 libstdc++ libstdc++.i686 libstdc+±devel libstdc+±devel.i686 libxcb libxcb.i686 make nfs-utils net-tools smartmontools sysstat unixODBC unixODBC-devel gcc gcc-c++ libXext libXext.i686 zlib-devel zlib-devel.i686
修改内核参数
vim /etc/sysctl.conf
fs.file-max = 6815744
kernel.sem = 250 32000 100 128
kernel.shmmni = 4096
kernel.shmall = 1073741824
kernel.shmmax = 4398046511104
kernel.panic_on_oops = 1
net.core.rmem_default = 262144
net.core.rmem_max = 4194304
net.core.wmem_default = 262144
net.core.wmem_max = 1048576
net.ipv4.conf.all.rp_filter = 2
net.ipv4.conf.default.rp_filter = 2
fs.aio-max-nr = 1048576
net.ipv4.ip_local_port_range = 9000 65500
刷新内核参数表: /sbin/sysctl –p
修改内核限制参数
vi /etc/security/limits.conf
Default limit for number of user’s processes to prevent
accidental fork bombs.
See rhbz #432903 for reasoning.

1.1.2. 创建oracle帐号和组
groupadd oinstall
groupadd dba
groupadd oper
useradd -g oinstall -G dba,oper -d /home/oracle oracle
passwd oracle 设置密码
1.1.3. 修改oracle环境变量
mkdir /usr/local/oracle
mkdir /usr/local/oracle/logs
su – oracle
vi .bash_profile (文件最后加入)
