有时候会遇到命令行安装oracle和建库，没事就做个试验记录下
1.配置Yum源及关闭SeLinux
[root@rhel65 mnt]# mount /dev/sr0 /mnt
mount: block device /dev/sr0 is write-protected, mounting read-only
[root@rhel65 ~]# cat /etc/yum.repos.d/iso.repo
[iso]
name=iso
baseurl=file:///mnt
enabled=1
gpgcheck=0
[root@rhel65 ~]# vi /etc/selinux/config
SELINUX=disabled
2.检查安装必要的rpm包
rpm -q binutils compat-libstdc++-33 elfutils-libelf elfutils-libelf-devel expat gcc gcc-c++ glibc glibc-common glibc-devel glibc-headers libaio libaio-devel libgcc libstdc++ libstdc++-devel make pdksh sysstat
与上面不同，待检查
yum -y install binutils binutils-devel compat-libcap1 compat-libstdc++-33 compat-libstdc++-33.i686 ksh elfutils-libelf elfutils-libelf-devel glibc glibc-common glibc-devel glibc-headers gcc gcc-c++ libaio libaio.i686 libaio-devel libaio-devel.i686 libgcc libstdc++ libstdc++.i686 libstdc++-devel libstdc++-devel.i686 make sysstat unixODBC unixODBC-devel libXp libXp-devel libXpm-devel telnet
3.修改sysctl.conf文件
vi /etc/sysctl.conf
kernel.shmmax = 2147483648
kernel.shmmni = 4096
kernel.shmall = 2097152
kernel.sem = 250 32000 100 128
fs.file-max = 6815744
fs.aio-max-nr = 1048576
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 = 1048576
以上几个内核参数的大致含义如下
kernel.shmma：最大共享内存段，以字节为单位，物理内存*1024*1024*2，为物理内存的2倍。
kernel.shmmni：整个系统共享内存段的最大数目。
kernel.shmall：共享内存总量，以页为单位。
kernel.sem：每个信号对象集的最大信号对象数；系统范围内最大信号对象数；每个信号对象支持的最大操作数；系统范围内最大信号对象集数。
fs.file-max：文件句柄数，表示在Linux系统中可以打开的文件数量。
net.ipv4.ip_local_port_range：应用程序可使用的IPv4端口范围。
net.core.rmem_default：套接字接收缓冲区大小的缺省值
net.core.rmem_max：套接字接收缓冲区大小的最大值
net.core.wmem_default：套接字发送缓冲区大小的缺省值
net.core.wmem_max：套接字发送缓冲区大小的最大值
使内核参数实时生效
sysctl -p
4.Oracle用户设置Shell限制
vi /etc/security/limits.conf
oracle soft nproc 65536
oracle hard nproc 65536
oracle soft nofile 65536
oracle hard nofile 65536
5.session登录安全设置
vi /etc/pam.d/login #增加以下一行
session required pam_limits.so
在/etc/profile末尾增加oracle相关限制
vi /etc/profile
#Oracle判断
if [ $USER = "oracle" ]; then
if [ $SHELL = "/bin/ksh" ]; then
ulimit -p 16384
ulimit -n 65536
else
ulimit -u 16384 -n 65536
fi
umask 022
fi
6.创建oracle用户,组（root用户）
创建Oracle安装组oinstall,数据库管理员组dba，及oracle用户
cat /etc/group
groupadd -g 54321 oinstall
groupadd -g 54322 dba
useradd -u 54321 -m -d /home/oracle -g oinstall -G dba oracle
echo "oarcle" | passwd --stdin oracle
id oracle
uid=54321(oracle) gid=54321(oinstall) 组=54321(oinstall),54322(dba)
groupadd oinstall 是创建用户组,用来做oracle的安装和维护工作
useradd 是创建用户
-m –d /home/oracle 是把/home/oracle目录作为oracle用户的主目录或登录默认目录
–g oinstall 是表示oracle用户的初始组为oinstall
–G dba 是表示oracle用户同时属于dba组,做数据维护,和数据库管理工作
/*
/usr/sbin/groupadd oinstall
/usr/sbin/groupadd dba
/usr/sbin/useradd -g oinstall -G dba oracle（主组oinstall，其它组：dba）
--passwd oracle
echo "oarcle" | passwd --stdin oracle
一句话修改账户密码的命令 echo "密码" | passwd --stdin 用户名
下面是最简单的创建
groupadd oinstall
groupadd dba
useradd -g oinstall -G dba oracle
echo "oarcle" | passwd --stdin oracle
chmod -R 700 /home/oracle
*/
7.创建安装目录
mkdir -p /u01/app/oracle
--创建数据文件路径
mkdir -p /u01/app/oracle/oradata
mkdir -p /u01/app/oraInventory
--创建闪回路径
mkdir -p /u01/app/oracle/fast_recovery_area
mkdir -p /u01/app/oracle/product/11.2.0/db_1
chown -R oracle:oinstall /u01/app/oracle
chown -R oracle:oinstall /u01/app
chmod -R 755 /u01/app
8.创建 oracle bash_profile
su - oracle
vi .bash_profile
--下面创建DBNAME为TESTDB，执行前批量替换成自己喜欢的名字
export PATH
export ORACLE_BASE=/u01/app/oracle;
export ORACLE_HOME=$ORACLE_BASE/product/11.2.0/db_1;
export ORACLE_SID=testdb;
export ORACLE_UNQNAME=testdb;
export ORACLE_TERM=xterm;
export PATH=$ORACLE_HOME/bin:$PATH;
export LD_LIBRARY_PATH=$ORACLE_HOME/lib:/lib:/usr/lib;
export CLASSPATH=$ORACLE_HOME/JRE:$ORACLE_HOME/jlib:$ORACLE_HOME/rdbms/jlib
#数据库编码 ZHS16GBK/UTF8 任选一个
export NLS_LANG=AMERICAN_AMERICA.ZHS16GBK
#数据库时间格式
export NLS_DATE_FORMAT=YYYY/MM/DD
export EDITOR=vi
export NLS_DATE_FORMAT='yyyy/mm/dd hh24:mi:ss'
export SQLPATH=/home/oracle/sqlpath
umask 022
#set -o vi
stty erase ^h
set line 189 pages 200
set time on
alias sql='sqlplus / as sysdba'
alias trace='cd /u01/app/oracle/diag/rdbms/testdb/testdb/trace'
alias oralog='cd /u01/app/oracle/diag/rdbms/rac/rac1/trace/'
alias network='cd /u01/app/oracle/product/11.2.0/db_1/network/admin/'
echo '################### 测试环境 ########################'
echo '0. rac: export ORACLE_SID=testdb; export DBNAME=testdb';
echo ' ';
#以下两个设置是用来设置rlwrap插件的环境，用来支持命令行回显功能
#alias sqlplus="rlwrap sqlplus"
#alias rman="rlwrap rman"
--使配置生效
source /home/oracle/.bash_profile
或
[oracle@testdb ~]# . /home/oracle/.bash_profile
检查环境变量是否生效
env |grep ORA
9.解压文件
unzip ...
10.静默文件配置/单节点为例

解决方法：修改hosts文件
[root@test220 ~]# vi /etc/hosts
192.168.X.X test220
//
一、主机信息查看
1、查看主机名 uname -a
2、查看主机版本 cat /etc/redhat-release
3、查看主机IP ifconfig -a
4、查看hosts解析 cat /etc/hosts
5、查看主机时间 date
6、查看主机磁盘 df -h
7、查看存储配置 multipath -l
8、查看主机防火墙 service iptables status
9、查看selinux配置 cat /etc/selinux/config
10、查看存储超时时间 cat /sys/block/sdb/device/timeout
11、查看系统硬件时钟 hwclock --show
二、主机基础信息可能的修改
1、修改主机时间 date -s 14:20:50
2、硬件同步的系统时钟 clock --systohc
系统同步硬件的时钟 clock --hctosys
3、停止防火墙 service iptables stop
防火墙不开机启动 chkconfig iptables off
确认防火墙状态 service iptables status
防火墙开机启动确认 chkconfig --list|grep iptables
4、删除主机ntp配置文件 rm -rf /etc/ntp.conf
5、修改selinux配置 sed -i '/enforcing/s/SELINUX=enforced/SELINUX=disabled/g' /etc/selinux/config
确认selinux修改 cat /etc/selinux/config
设置sar
默认sar记录为10分钟一次，改为1分钟一次
日志保存目录为/var/log/sa
运行频率修改，把时间*/10改为*/1，出下面
# vi /etc/cron.d/sysstat
# run system activity accounting tool every 10 minutes
*/1 * * * * root /usr/lib64/sa/sa1 1 1
如果没有配置文件则需要安装sysstat-7.0.2-3.el5_5.1.x86_64.rpm包
日志保存时间，改为30天
# vi /etc/sysconfig/sysstat
HISTORY=30
增强提示符
为了使用同一用户oracle更好的分辨在哪个ORACLE_HOME中，使用以下增强的命令提示符
vi /etc/profile
export PS1='[ u(${ORACLE_HOME##*/})@h W]$ '
设置SQLPATH目录
sqlpath目录中的login.sql设置了登录sqlplus的环境变量
mkdir -p /home/oracle/sqlpath
vi login.sql
set TERM OFF
define_editor=vim
define loginname=idle
column global_name new_value loginname

在安装过程中涉及的几个文件位置及用途
/etc/sysctl.conf (修改内核参数)
/etc/security/limits.conf (shell对oracle用户的限制)
/etc/pam.d/login
/etc/profile (系统相关的环境变量)
/home/oracle/.bash_profile (oracle用户相关的环境变量)
/home/oracle(确保本目录空间足够大)
/etc/hosts (建立ip和机器名的关系，通过uname把地址和机器名关联，否则在安装数据库时报监听器错误)
/etc/sysconfig/network 修改机器名
使用yum安装缺失的rpm包
yum list
yum -y install rpm_name.rpm
yum makecache 是将服务器上的软件包信息 现在本地缓存,以提高 搜索 安装软件的速度
man yum 查看yum的帮助信息
yum 主要的一下命令如下:
yum search 软件包 搜索软件包
yum install 软件包 安装软件包
yum remove 软件包
yum update 更新系统
yum clean all 清除缓存目录下的软件包及旧的headers
执行完 yum makecache之后，你可以用
yum search subversion和yum -C search subversion 二者差别挺明显的，前者明显比后者慢
修改启动参数打开归档和闪回
# 修改spfile参数
alter system set log_archive_dest_1='location=/doea5/arch';
alter system set log_archive_format='arch_%t_%s_%r.log' scope=spfile;
alter system set db_recovery_file_dest_size=20G scope=spfile;
alter system set db_recovery_file_dest='/oracle/app/oracle/flash_recovery';
alter system set db_flashback_retention_target=10080 scope=spfile;
alter system set undo_retention=10800;
# 打开归档和闪回
shutdown immediate
startup mount
alter database archivelog ;
alter database flashback on;
alter database open;
防火墙设置
在文件【/etc/sysconfig/iptables】内增加以下内容：
-A INPUT -m state --state NEW -m tcp -p tcp --dport 22 -j ACCEPT
-A INPUT -m state --state NEW -m tcp -p tcp --dport 1521 -j ACCEPT
-A INPUT -m state --state NEW -m tcp -p tcp --dport 1158 -j ACCEPT
Oracle远程访问端口默认是1521，OEM端口1158，若自定义新端口，请开放相应端口。
（新开放端口的配置必须紧跟着放在端口22的配置后面）
重启防火墙
[root@oracle sysconfig]# service iptables restart
关闭selinux和iptables
iptables -F
iptables -x
编辑/etc/selinux/config，状态变成disabled
chown oracle:oinstall -R /tmp/database
chmod +x -R /tmp/database
修改操作系统启动模式
把level 5的图形界面改为level 3的字符界面，启动操作系统后会进入字符界面
# vi /etc/inittab
id:3:initdefault:
清空resolv.conf
在生产环境中，不建议使用resolve.conf解析域名，可能会使客户端登录缓慢，建议清空它
vi /etc/resolv.conf
清空
参考下面进行参数设置
https://www.linuxidc.com/Linux/2016-11/137543.htm
增强提示符
为了使用同一用户oracle更好的分辨在哪个ORACLE_HOME中，使用以下增强的命令提示符
# vi /etc/profile
export PS1='[ u(${ORACLE_HOME##*/})@h W]$ '
配置NTP服务
根据公司的NTP策略，需要布置NTP脚本，从IDC处取得ntpd-deploy.sh
目前有一份脚本存放在/u07/system_configuration/ntpd/for_linux目录
如果时间与实现的时间相关太多，先使用ntpdate手工同步一下
# ntpdate ntp-hb1.99bill.com
# ./ntpd-deploy.sh hb
GI环境的ntpd需要加上-x参数
# vi /etc/sysconfig/ntpd
加上参数-x
OPTIONS="-x -u ntp:ntp -p /var/run/ntpd.pid"
为了保证BIOS时间和系统时间差别太大，ntpd会不同步，在系统重启时增加自动同步一次的脚本
# vi /etc/rc.local
ntpdate ntp-hb1.99bill.com
设置sar
默认sar记录为10分钟一次，改为1分钟一次
日志保存目录为/var/log/sa
运行频率修改，把时间*/10改为*/1，出下面
# vi /etc/cron.d/sysstat
# run system activity accounting tool every 10 minutes
*/1 * * * * root /usr/lib64/sa/sa1 1 1
如果没有配置文件则需要安装sysstat-7.0.2-3.el5_5.1.x86_64.rpm包
日志保存时间，改为30天
# vi /etc/sysconfig/sysstat
HISTORY=30
