Oracle RAC 12cR1的安装

安装12cR1对内存的要求比较高， 本次测试安装，两个节点分配了4800M的内存。但是安装的时候，发现内存占用比较厉害。

安装GI的过程比较慢，而且发现内存几乎被耗光，安装Oracle的时候，还是比较快的。

安装过程如下：

/etc/hosts 设置 

127.0.0.1       localhost.localdomain   localhost
# Public
192.168.2.201   host01
192.168.2.202   host02
# Private
10.10.10.1     host01-priv
10.10.10.2     host02-priv
# Virtual
192.168.2.101   host01-vip
192.168.2.102   host02-vip
# SCAN
192.168.2.111  scan 

创建组和用户 

groupadd --gid 54321 oinstall
groupadd --gid 54322 dba
groupadd --gid 54323 asmdba
groupadd --gid 54324 asmoper
groupadd --gid 54325 asmadmin
groupadd --gid 54326 oper
groupadd --gid 54327 backupdba
groupadd --gid 54328 dgdba
groupadd --gid 54329 kmdba
useradd --uid 54321 --gid oinstall --groups dba,oper,asmdba,asmoper,backupdba,dgdba,kmdba oracle
# passwd oracle
useradd --uid 54322 --gid oinstall --groups dba,asmadmin,asmdba,asmoper grid
# passwd grid

ntp 设置 

[root@host01 etc]# mv ntp.conf ntp.conf_bak
[root@host02 etc]# mv ntp.conf ntp.conf_bak

安装包，12cR1需要以下安装包

binutils
compat-libcap1
compat-libstdc++-33
gcc
gcc-c++
glibc
glibc-devel
ksh
libgcc
libstdc++
libstdc++-devel
libaio
libaio-devel
libXext
libXtst
libX11
libXau
libxcb
libXi
make
sysstat
libXmu
libXt
libXv
libXxf86dgak
libXxf86misc
libXxf86vm
xorg-x11-utils
xorg-x11-xauth
nfs-utils

配置YUM

[root@host02 etc]# cd /etc/yum.repos.d/
[root@host02 yum.repos.d]# rm -rf *.repo
[root@host02 yum.repos.d]# 

vi rhel-info.repo

[Server]
name=Server
baseurl=file:///mnt/Server
enabled=1
gpgcheck=1
gpgkey=file:///mnt/RPM-GPG-KEY-redhat-release

yum clean all
yum update

把需要安装的包，写在一个临时文件中，然后使用awk和yum组合命令来安装

vi /tmp/req-rpm.txt
yum install `awk '{print $1}'  /tmp/req-rpm.txt`

OS的配置

vi /etc/selinux/config 
SELINUX=enforcing
setenforce 1

配置 shm 等  /etc/sysctl.conf 

kernel.shmmax = 4398046511104
kernel.shmall = 1073741824
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 = 1048576
fs.aio-max-nr = 1048576
fs.file-max = 6815744
kernel.panic_on_oops = 1

配置Limits.conf

-- vi /etc/security/limits.conf 


oracle soft nproc 16384
oracle hard nproc 16384
oracle soft nofile 1024
oracle hard nofile 65536
oracle soft stack 10240
oracle hard stack 32768
grid soft nproc 16384
grid hard nproc 16384
grid soft nofile 1024
grid hard nofile 65536
grid soft stack 10240
grid hard stack 32768

vi /etc/pam.d/login

session    required     pam_limits.so

vi /etc/profile

if [ $USER = "oracle" ]; then
if [ $SHELL = "/bin/ksh" ]; then
ulimit -u 16384
ulimit -n 65536
else
ulimit -u 16384 -n 65536
fi
fi
if [ $USER = "grid" ]; then
if [ $SHELL = "/bin/ksh" ]; then
ulimit -u 16384
ulimit -n 65536
else
ulimit -u 16384 -n 65536
fi
fi

创建文件夹

mkdir --parents /u01/app/grid
chown --recursive grid.oinstall /u01/


mkdir /u01/app/oracle
chown --recursive oracle.oinstall /u01/app/oracle

添加共享磁盘

VBoxManage createhd --filename D:\rac12c_asm\asmocr1.vdi --size 4096 --format VDI --variant Fixed     
VBoxManage createhd --filename D:\rac12c_asm\asmocr2.vdi --size 4096 --format VDI --variant Fixed
VBoxManage createhd --filename D:\rac12c_asm\asmocr3.vdi --size 4096 --format VDI --variant Fixed
VBoxManage createhd --filename D:\rac12c_asm\asmdata1.vdi --size 102400 --format VDI --variant Fixed

将共享磁盘挂在节点1和节点2上

VBoxManage storageattach host01 --storagectl "SATA" --port 1 --device 0 --type hdd --medium D:\rac12c_asm\asmocr1.vdi  --mtype shareable
VBoxManage storageattach host01 --storagectl "SATA" --port 2 --device 0 --type hdd --medium D:\rac12c_asm\asmocr2.vdi  --mtype shareable
VBoxManage storageattach host01 --storagectl "SATA" --port 3 --device 0 --type hdd --medium D:\rac12c_asm\asmocr3.vdi  --mtype shareable
VBoxManage storageattach host01 --storagectl "SATA" --port 4 --device 0 --type hdd --medium D:\rac12c_asm\asmdata1.vdi --mtype shareable

VBoxManage storageattach host02 --storagectl "SATA" --port 1 --device 0 --type hdd --medium D:\rac12c_asm\asmocr1.vdi  --mtype shareable
VBoxManage storageattach host02 --storagectl "SATA" --port 2 --device 0 --type hdd --medium D:\rac12c_asm\asmocr2.vdi  --mtype shareable
VBoxManage storageattach host02 --storagectl "SATA" --port 3 --device 0 --type hdd --medium D:\rac12c_asm\asmocr3.vdi  --mtype shareable
VBoxManage storageattach host02 --storagectl "SATA" --port 4 --device 0 --type hdd --medium D:\rac12c_asm\asmdata1.vdi --mtype shareable

VBoxManage modifyhd D:\rac12c_asm\asmocr1.vdi  --type shareable 
VBoxManage modifyhd D:\rac12c_asm\asmocr2.vdi  --type shareable 
VBoxManage modifyhd D:\rac12c_asm\asmocr3.vdi  --type shareable 
VBoxManage modifyhd D:\rac12c_asm\asmdata1.vdi --type shareable 

配置UDEV

  /sbin/scsi_id -g -u -d /dev/sdb   -- 6的格式

1ATA_VBOX_HARDDISK_VB8bd65052-55e13b1a
1ATA_VBOX_HARDDISK_VB891c85f2-51b4d83d
