readhat 安装11gr2文档
需要注意的地方：必须关掉的 1，防火墙；2，SElinux 。
root 用户运行 setup 命令可关防火墙与SElinux
修改网络配置文件，一定要重启此文件才能生效。
linux安装oracle 10g 第三步出现sid不能使用，因为之前已经使用过这个sid ,解决办法：把/etc/oratab 最后一条记录删除
1. 检查内存，至少1G
grep MemTotal /proc/meminfo
2.交换分区
Available RAM
Swap Space Required
Between 1 GB and 2 GB 1.5 times the size
of RAM
Between 2 GB and 16 GB Equal to the size
of RAM
More than 16
GB 16 GB
grep
"model name" /proc/cpuinfo
grep SwapTotal /proc/meminfo

3.
共享内存段至少要大于MEMORY_MAX_TARGET and MEMORY_TARGET
[[email protected] ~]# df -k /dev/shm/

4.
至少1G的 /tmp
df -h /tmp

7.
安装必备的软件包
yum
-y install compat-db-4*
yum -y install libaio-0*
yum -y install compat-libstdc++-33-3*
yum -y install compat-gcc-34-3*
yum -y install compat-gcc-34-c++-3*
yum -y install libXp-1*
yum -y install openmotif-2*
yum -y install gcc-4*
yum -y install glibc*
8.
创建组和用户
/usr/sbin/groupadd oinstall
/usr/sbin/groupadd dba
/usr/sbin/useradd -g oinstall -G dba oracle
如果oracle用户已经存在
/usr/sbin/usermod -g oinstall -G dba oracle
echo
oracle | passwd --stdin oracle
9.
修改内核参数
shmmax
- 共享内存段的最大字节数，建议设大点，甚至可以大过物理内存的字节数
shmmin - 共享内存段的最小尺寸.
shmmni - 共享内存段的最大数目.
shmseg - 每个进程可分配的最大共享内存段数目.
shmall - 最大的并发共享内存段数目，比SGA还要大.
semmns - 信号灯的最大数量，跟ORACLE的PROCESS数有关.
semmsl - 每个信号灯集合中最多的信号灯数目.
vi
/etc/sysctl.conf
kernel.shmall
= 2097152
kernel.shmmax = 536870912
kernel.shmmni = 4096
kernel.sem = 250 32000 100 128
fs.file-max = 65536
net.ipv4.ip_local_port_range = 1024 65000
net.core.rmem_default=262144
net.core.rmem_max=262144
net.core.wmem_default=262144
net.core.wmem_max=262144
修改完执行此命令 ： sysctl -p
10.
vi /etc/security/limits.conf
oracle
soft nproc 2047
oracle
hard nproc 16384
oracle
soft nofile 1024
oracle
hard nofile 65536
11.
vi /etc/pam.d/login
session required pam_limits.so
12.
修改profile
if [ $USER = "oracle" ]; then
if [ $SHELL = "/bin/ksh"
]; then
ulimit -p 16384
ulimit -n 65536
else
ulimit -u 16384 -n 65536
fi
fi
13.
创建目录结构
mkdir
-p /u01/app/oracle/product/10.2/db_1
chown -R oracle:oinstall /u01/app/
chmod -R 775 /u01/app/
14.
vi
/home/oracle/.bash_profile
export ORACLE_BASE=/u01/app/oracle
export ORACLE_HOME=$ORACLE_BASE/product/10.2/db_1
export ORACLE_SID=orcl
export PATH=$ORACLE_HOME/bin:$PATH
15.
./runInstaller
-ignoreSysPrereqs
rlwrap-0.30
的安装
tar
zxvf rlwrap-0.30.tar(文件名)
cd /rlwrap-0.30
./configure --prefix=/usr/local/rlwrap
make && make install
vi
/home/oracle/.bash_profile
alias sqlplus=‘/usr/local/rlwrap/bin/rlwrap sqlplus‘
alias rman=‘/usr/local/rlwrap/bin/rlwrap rman‘
su

sqlplus
以oracle身份安装
./runInstaller -ignoreSysPrereqs
