Oracle专题一之Oracle的安装

10g安装

配置YUM源（国内阿里的还不错，也可以配置挂载的yum源）
yum install -y binutils compat-db control-center gcc* glibc libXp libstdc++ libstdc++-devel make openmotif sysstat control-center
root用户设置内核参数
vi /etc/sysctl.conf
kernel.shmall = 2097152(共享内存,单位是页面数，每个页面数是4K，就是块大小，操作系统ext3的，一个块是4K，设置共享内存8G，官方推荐值，生产中可以自行改大，8GB/4KB=8388608KB /4KB=2097152（页）)
kernel.shmmax = 2147483648 (单个共享内存段的最大尺寸，单位字节，单次提取最多2G，不是数据仓库完全够用2G=210241024*1024(byte))
kernel.sem = 250 32000 100 128 (信号量)
fs.file-max = 65536 (文件句柄的最大数量)
net.ipv4.ip_local_port_range = 1024 65000 (端口范围)
net.core.rmem_default = 262144(默认读内存大小)
net.core.rmem_max = 262144(读内存最大值)
net.core.wmem_default = 262144(默认写存大小)
net.core.wmem_max = 262144(写内存最大值)
修改Linux版本号
vi /etc/redhat-release (修改版本号，oracle10g只支持到redhat版本4，如果不修改，检测安装环境会报错)
Red Hat Enterprise Linux Server release 3 (Tikanga)）

使内核生效
vi /etc/security/limits.conf

    oracle          soft    nproc           2047
    oracle          hard    nproc           16384
    oracle          soft    nofile          1024
    oracle          hard    nofile          65536

    #core - 限制内核文件的大小

#date - 最大数据大小
　　 #fsize - 最大文件大小
　　 #memlock - 最大锁定内存地址空间
　　 #nofile - 打开文件的最大数目
　　 #rss - 最大持久设置大小
　　 #stack - 最大栈大小
　　 #cpu - 以分钟为单位的最多 CPU 时间
　　 #noproc - 进程的最大数目
　　 #as - 地址空间限制
　　 #maxlogins - 此用户允许登录的最大数目)
```

    /sbin/sysctl –p
    vi /etc/pam.d/login
    在下面添加以下信息
    session    required     /lib/security/pam_limits.so

用户环境变量
groupadd oinstall
groupadd dba
useradd -g oinstall -G dba oracle
passwd oracle
su -l oracle
vi .bash_profile
stty erase ^H //删除键
ORACLE_BASE=/oracle/app
ORACLE_HOME=$ORACLE_BASE/oracle/product/10.2.0/db_1 //家目录
ORACLE_SID=ecom //实例名（与Oracle实例名相同）
PATH=$PATH:$HOME/bin:$ORACLE_HOME/bin
LD_LIBRARY_PATH=$ORACLE_HOME/lib:/usr/lib
NLS_LANG=AMERICAN_AMERICA.ZHS16GBK //字符集
export ORACLE_BASE ORACLE_HOME ORACLE_SID PATH LD_LIBRARY_PATH NLS_LANG
source .bash_profile
开始安装
mkdir -p /oracle/app
chmod 777 /oracle
chown -R oracle:oinstall /oracle
unzip oracle_database_linux32.zip

在上面图片出来之后切换到root下执行以下脚本

按ok 退出
输入dbca 进入安装

11g脚本安装
