[RAC] 虛擬機linux7.0 + oracle12cr2 RAC + asm 安裝

1.主機名規(guī)劃

vps+3nZEm+sFS5WD4dGxwiwvZtf6bREdK/xxAZgDogXmgGiBOeARA6ZwOS08YsAShUcsbhy8d8Pt2CV2td8W8bG6Qf8HdZh7RPvzWmsAAAAASUVORK5CYII=">

2.OS安裝(具體過程略過)

swap規(guī)則: 內(nèi)存<8G則物理內(nèi)存2倍，>8G <16G 則等于物理內(nèi)存，>16G物理內(nèi)存一半

3.OS準備工作

(1).關(guān)閉防火墻

systemctl status firewalld  查看防火墻狀態(tài)
systemctl stop firewalld  關(guān)閉防火墻
systemctl disable firewalld  禁用防火墻

(2).關(guān)閉selinux

getenforce 查看selinux的模式

修改/etc/selinux/config 文件，SELINUX=enforce –> disable

#setenforce 0  配置生效

(3).設置FTP

查看 getsebool -a |grep ftp

修改權(quán)限

setsebool ftpd_use_nfs on

setsebool ftp_home_dir on

setsebool ftpd_full_access on

setsebool ftpd_use_passive_mode on

允許root登錄FTP

注釋掉ftpusers和user_list 中的root行
重啟服務systemctl restart vsftpd.service

(4).配置yum

刪除rm /etc/yum.repos.d/packagekit-media.repo
建立 local.repo 文件
[test]
name=test
baseurl="file:///run/media/root/RHEL-7.0 Server.x86_64"
gpgcheck=0
enable=1

# yum clean all
# yum list

chown -R grid:oinstall /oracle

mkdir -p /oracle/app/oraInventory

(13).配置環(huán)境變量
grid
PS1="[`whoami`@`hostname`:"'$PWD]$'
export PS1
umask 022
export TMP=/tmp
export LANG=en_US
export TMPDIR=$TMP
export ORACLE_HOSTNAME=rac1
export ORACLE_SID=+ASM1
export ORACLE_TERM=xterm
export ORACLE_BASE=/oracle/app/grid
export ORACLE_HOME=/oracle/app/12.2.0.1/grid
export NLS_DATE_FORMAT="yyyy-mm-dd HH24:MI:SS"
PATH=.:$PATH:$HOME/bin:$ORACLE_HOME/bin; export PATH
export THREADS_FLAG=native

oracle
PS1="[`whoami`@`hostname`:"'$PWD]$'
export PS1
umask 022
export TMP=/tmp
export LANG=en_US
export TMPDIR=$TMP
export ORACLE_HOSTNAME=rac1
export ORACLE_UNQNAME=racdb12c
export ORACLE_BASE=/oracle/app/oracle
export ORACLE_HOME=$ORACLE_BASE/product/12.2.0.1/db_1

export NLS_LANG=AMERICAN_AMERICA.ZHS16GBK
PATH=.:$PATH:$HOME/bin:$ORACLE_HOME/bin; export PATH
export THREADS_FLAG=native

(14).配置SSH

在主節(jié)點上以grid,oracle用戶身份生成公鑰和私鑰
mkdir ~/.ssh
ssh-keygen -t rsa
ssh-keygen -t dsa

在另外的節(jié)點上執(zhí)行相同的操作
在1節(jié)點使用oracle(grid)用戶執(zhí)行以下操作
cat ~/.ssh/id_rsa.pub >> ./.ssh/authorized_keys
cat ~/.ssh/id_dsa.pub >> ./.ssh/authorized_keys
ssh rac2 cat ~/.ssh/id_rsa.pub >> ~/.ssh/authorized_keys
ssh rac2 cat ~/.ssh/id_dsa.pub >> ~/.ssh/authorized_keys
scp ~/.ssh/authorized_keys rac2:~/.ssh/authorized_keys

在1,2節(jié)點上測試ssh
ssh rac1 date
ssh rac2 date
ssh rac1-priv date
ssh rac2-priv date

4.修改虛擬機配置文件(.vmx),添加以下內(nèi)容
disk.locking = "FALSE"
diskLib.dataCacheMaxSize = "0"
diskLib.dataCacheMaxReadAheadSize = "0"
diskLib.dataCacheMinReadAheadSize = "0"
diskLib.dataCachePageSize = "4096"
diskLib.maxUnsyncedWrites = "0"
disk.EnableUUID = "TRUE"
scsi1.sharedBus = "VIRTUAL"

5.配置共享存儲

(1).編輯/etc/scsi_id.config，添加下面內(nèi)容
options=--whitelisted --replace-whitespace

(2).獲取需要綁定ASM Disk磁盤的uuid
for i in b c d e f g;
do
echo "sd$i" "`/usr/lib/udev/scsi_id --whitelisted --replace-whitespace --device=/dev/sd$i`";
done

sdb 36000c29b0e11cfc09873aa3dc45baf3e
sdc 36000c293313041c3f662d837263cbef3

sde 36000c29cb127c1af8c28efd8af0d92d4
sdf 36000c29ecd42be581ecb6d8f2b37e2f1
sdg 36000c29e8abe980615022c02a11960d1

(3).編寫udev rules 文件
for i in b c d e f g;
do
echo "KERNEL==\"sd*\",BUS==\"scsi\",PROGRAM==\"/usr/lib/udev/scsi_id --whitelisted --replace-whitespace --device=/dev/\$name\",RESULT==\"`/usr/lib/udev/scsi_id --whitelisted --replace-whitespace --device=/dev/sd$i`\",NAME=\"asm-disk$i\",OWNER=\"grid\",GROUP=\"asmadmin\",MODE=\"0660\""
done

redhat 7

# vi /etc/udev/rules.d/99-oracle-asmdevices.rules
#/sbin/udevadm trigger --type=devices --action=change

(4).重啟udev設備
/sbin/udevadm control –reload-rules
/sbin/start_udev  #redhat7 整合到systemctl restart systemd-udev-trigger.service 中
ll /dev/asm*
