c) 用户组与文件系统规划
用户组和文件系统配置
软件 用户 主组 辅助组 ORACLE_BASE ORACLE_HOME
GI grid oinstall dba,asmadmin,asmdba,asmoper,racdba /oracle/app/grid /oracle/app/12.2.0/grid
DB oracle oinstall dba,oper,asmdba, asmadmin,racdba,backupdba,dgdba,kmdba /oracle/app/oracle $ORACLE_BASE/product/12.2.0/db_1
d) 网络规划
1. 优先双网卡绑定原则
2. 优先私有网络万兆网卡原则
3. 避免使用169.254.*.* 地址原则
/etc/hosts列表如下
名称 对应网卡 IP 用途
bmcdb1 bond0 10.151.115.71 public
bmcdb1-vip 10.151.115.73 VIP
bmcdb1-priv bond1 192.155.1.171 private
bmcdb2 bond0 10.151.115.72 public
bmcdb2-vip 10.151.115.74 VIP
bmcdb2-priv bond1 192.155.1.172 private
scan-bmcdb 10.151.115.75 scan-ip
e) 存储规划
1. 设置disk I/O schedulers为Deadline
# echo deadline > /sys/block/${ASM_DISK}/queue/scheduler
2. 绑定存储LUN属性,保证系统重启属性不变
3. ASM规划表
ASM规划表
磁盘组名 分区 属主 权限 单个LUN大小 冗余 总容量
OCR emcpowera grid:asmadmin 660 18G
emcpowerb grid:asmadmin 660 18G Normal 54G
emcpowerc grid:asmadmin 660 18G
DATA emcpowere grid:asmadmin 660 200G External 200G
FRA emcpowerf grid:asmadmin 660 100G External 100G
OCR 磁盘组：保存CRS信息及Voting disk等信息
DATA磁盘组：保存数据文件、控制文件
FRA磁盘组：保存节点的归档文件
2. Oracle RAC所有集群节点准备
a) 硬件检验
1. 操作系统基础环境检验
# 操作系统发行版
cat /etc/redhat-release
# 内核版本
uname -a
# Memory total
grep MemTotal /proc/meminfo
# SWAP Total
grep SwapTotal /proc/meminfo
# tmp目录大小
df -h /tmp
# 当前内存和swap使用状态
free -g
# 共享内存大小
df -h /dev/shm
# CPU 型号,物理个数,核数,逻辑个数
cat /proc/cpuinfo | grep name | cut -f2 -d: | uniq -c
cat /proc/cpuinfo| grep "physical id"| sort| uniq| wc -l
cat /proc/cpuinfo| grep "cpu cores"| uniq
cat /proc/cpuinfo| grep "processor"| wc -l
# 节点信息收集省略
2. 双网卡绑定
# 双网卡绑定采用主备模式,双节点保持Bond模式一置,并持续ping,拔物理线进行测试

1.3 rpm包再次检验
# 还是使用上面的脚本,直到无软件包输出为止
2. 操作系统创建软件安装组及用户(oracle,grid)
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
groupadd --gid 54330 racdba
useradd --uid 54321 --gid oinstall --groups dba,oper,asmdba,asmadmin,racdba,backupdba,dgdba,kmdba oracle
passwd oracle
useradd --uid 54322 --gid oinstall --groups dba,asmadmin,asmdba,asmoper,racdba grid
passwd grid
3. 操作系统创建软件安装目录
vi /etc/oraInst.loc
inventory_loc=/oracle/app/oraInventory
inst_group=oinstall
# Create the Oracle Inventory Directory
# To create the Oracle Inventory directory, enter the following commands as the root user:
mkdir -p /oracle/app/oraInventory
chown -R grid:oinstall /oracle/app/oraInventory
chmod -R 775 /oracle/app/oraInventory
# Creating the Grid Infrastructure Base Directory
mkdir -p /oracle/app/grid
chown -R grid:oinstall /oracle/app/grid
chmod -R 775 /oracle/app/grid
# Creating the Oracle Grid Infrastructure Home Directory
mkdir -p /oracle/app/12.2.0/grid
chown -R grid:oinstall /oracle/app/12.2.0/grid
chmod -R 775 /oracle/app/12.2.0/grid
# Creating the Oracle Base Directory
mkdir -p /oracle/app/oracle
mkdir -p /oracle/app/oracle/cfgtoollogs
# needed to ensure that dbca is able to run after the rdbms installation.
chown -R oracle:oinstall /oracle/app/oracle
chmod -R 775 /oracle/app/oracle
# Creating the Oracle RDBMS Home Directory
mkdir -p /oracle/app/oracle/product/12.2.0/db_1
chown -R oracle:oinstall /oracle/app/oracle/product/12.2.0/db_1
chmod -R 775 /oracle/app/oracle/product/12.2.0/db_1
4. 操作系统内核参数优化
# 内存为128G,设置kernel.shmmax=70G,SGA=50G and PGA=10G
# kernel.shmmni该参数是系统共享内存段最大个数
# kernel.shmmax该参数是一个进程共享内存段最大尺度
# SHMMAX应略大于SGA尺寸
# kernel.shmall该参数是共享内存总量
# kernel.shmall大于shmmax/PAGE_SIZE
cat /etc/sysctl.conf
kernel.shmmni = 4096
kernel.shmmax = 75161927680
kernel.shmall = 18350080
kernel.sem = 250 32000 100 128
fs.file-max = 7553600
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
# 安装数据库实例后算出并添加此参数
vm.nr_hugepages = 25026
# 立即生效（root）
/sbin/sysctl -p
#NOTE: https://access.redhat.com/documentation/en-us/red_hat_enterprise_linux/5/html/ tuning_and_optimizing_red_hat_enterprise_linux_for_oracle_9i_and_10g_databases/index
#NOTE: The latest information on kernel parameter settings for Linux can be found in My Oracle Support ExtNote:169706.1.#
5. 操作系统内存优化
# Oracle一直建议关闭Transparent HugePages来优化内存的使用,
# 故关闭Transparent HugePages
grubby --default-kernel
grubby --args="transparent_hugepage=never" --update-kernel
grubby --info /boot/vmlinuz-3.10.0-514.el7.x86_64 >> /boot/grub2/grub.cfg
cat /sys/kernel/mm/transparent_hugepage/enabled
grep AnonHugePages /proc/meminfo
reboot
# 节点1执行展示结果
[root@bmcdb1 ~]# grubby --default-kernel
/boot/vmlinuz-3.10.0-514.el7.x86_64
[root@bmcdb1 ~]# grubby --args="transparent_hugepage=never" --update-kernel /boot/vmlinuz-3.10.0-514.el7.x86_64
# grubby --info /boot/vmlinuz-3.10.0-514.el7.x86_64 >> /boot/grub2/grub.cfg
cat /boot/grub2/grub.cfg

title=Red Hat Enterprise Linux Server (3.10.0-514.el7.x86_64) 7.3 (Maipo)
# 确认已关闭 Transparent HugePages
[root@bmcdb1 ~]# cat /sys/kernel/mm/transparent_hugepage/enabled
always madvise [never]
[root@bmcdb1 ~]# grep AnonHugePages /proc/meminfo
AnonHugePages: 0 kB
# reboot 展示结果忽略
6. 操作系统共享内存优化
# Redhat 7.2以后systemd-logind service引入了新的功能,用户注销时,删除所有IPC对象
# 避免用户中断时系统删除共享SGA内存,
# 导致ASM和database instance down机,故设置RemoveIPC=no
echo "RemoveIPC=no" >> /etc/systemd/logind.conf
systemctl restart systemd-logind
# ALERT: Setting RemoveIPC=yes on Redhat 7.2 and higher Crashes ASM and Database Instances as Well as Any Application That Uses a Shared Memory Segment (SHM) or Semaphores (SEM) (文档 ID 2081410.1)
# 节点1执行展示结果
[root@bmcdb1 ~]# echo "RemoveIPC=no" >> /etc/systemd/logind.conf
[root@bmcdb1 ~]# cat /etc/systemd/logind.conf
……中间展示忽略……
#RemoveIPC=no
RemoveIPC=no
# 设置共享内存
# 通过/etc/fstab设置共享内存
[root@bmcdb1 ~]# cat /etc/fstab
#
# /etc/fstab

7. 操作系统软件安装用户环境变量(oracle,grid)
# grid
[grid@Bmcdb1 ~]$ vi .bash_profile
export PS1="[`whoami`@`hostname`:"'$PWD]$'
export JAVA_HOME=/usr/local/java; export JAVA_HOME
export ORACLE_BASE=/oracle/app/grid
export ORACLE_HOME=/oracle/app/12.2.0/grid

export THREADS_FLAG=native;
export TEMP=/tmp
export TMPDIR=/tmp
umask=022
8. 操作系统用户(oracle,grid)硬性限制优化
# 提升用户硬性限制（Oracle、grid用户默认的硬性限制不满足GI安装和配置）
# limits.conf为PAM模板配置文件；所以应先配置PAM,即配置如下：
echo "session required pam_limits.so" >> /etc/pam.d/login
# RAC未运行之前,无法实际测量vm.nr_hugepages大小。
# 原则：Number Hugepages * Hugepagesize = minimum Memlock < RAM
cat /etc/security/limits.conf
oracle soft nproc 2047
oracle hard nproc 16384
oracle soft nofile 1024
oracle hard nofile 65536
oracle soft stack 10240
oracle hard stack 32768
oracle soft memlock 134144000
oracle hard memlock 134144000
grid soft nproc 2047
grid hard nproc 16384
grid soft nofile 1024
grid hard nofile 65536
grid soft stack 10240
grid hard stack 32768
#NOTE：What is Memlock and How to Calculate the Values for Memlock (文档 ID 2511230.1)
# shell开始文件限制提升
cat /etc/profile
if [ $USER = "oracle" ] || [ $USER = "grid" ]; then
if [ $SHELL = "/bin/ksh" ]; then
ulimit -p 16384
ulimit -n 65536
else
ulimit -u 16384 -n 65536
fi
umask 022
fi
9. 操作系统关闭防火墙和selinux
# 关闭防火墙
systemctl status firewalld
systemctl start firewalld.service
systemctl stop firewalld.service
systemctl disable firewalld.service
systemctl status firewalld
# 永久关闭selinux
cat /etc/sysconfig/selinux
SELINUX=disabled
10. 操作系统安装软件用户(oracle,grid)互信配置
# 在节点1配置ssh互信,步骤如下：
# 使用root将数据库软件拷贝至/home/oracle/下：
# 此脚本适合多节点安装优先使用
# chown oracle:oinstall linuxx64_12201_database.zip
# su - oracle
$ unzip linuxx64_12201_database.zip
$ cd database/sshsetup/
$ ./sshUserSetup.sh -user oracle -hosts "node1 node2" -advanced -noPromptPassphrase
$ ./sshUserSetup.sh -user grid -hosts "node1 node2" -advanced -noPromptPassphrase
# 检验互信
# 节点1, bmcdb1上执行检验操作
$ ssh bmcdb1 date;ssh bmcdb2 date;ssh bmcdb1priv date;ssh bmcdb2priv date
# 节点2, bmcdb2上执行检验操作
$ ssh bmcdb1 date;ssh bmcdb2 date;ssh bmcdb1priv date;ssh bmcdb2priv date
11. 操作系统使用/etc/hosts解析
# /etc/hosts解析地址如下
[oracle@bmcdb1 ~]$ cat /etc/hosts
127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4
::1 localhost localhost.localdomain localhost6 localhost6.localdomain6
# PUBLIC-IP
10.151.115.61 bmcdb1
10.151.115.62 bmcdb2
# VIP-IP
10.151.115.63 bmcdb1vip
10.151.115.64 bmcdb2vip
# PRIVATE-IP
192.155.1.161 bmcdb1priv
192.155.1.162 bmcdb2priv
# SCAN-IP
10.151.115.65 scanbmcdb
# 优先使用/etc/hosts,故files在dns前
[root@bmcdb1 ~]# cat /etc/nsswitch.conf | grep hosts
# hosts: db files nisplus nis dns
hosts: files dns myhostname
12. 操作系统时间同步配置NTP
# 每十分钟同步一次时间服务器,使用crontab定时任务调用ntpdate命令同步
检查系统时间
# date
# 公司内部时间服务器
[root@bmcdb1 soft]# crontab -l
*/10 * * * * /usr/sbin/ntpdate 10.151.113.73
[root@bmcdb2 ~]# crontab -l
*/10 * * * * /usr/sbin/ntpdate 10.151.113.73
3. Oracle RAC 共享存储准备
a) powerpath多路径软件聚合LUN成一条路径供系统使用
# powerpath安装及存储磁盘分配等工作请安排专业的存储工程师完成
# 节点1执行展示结果
[root@bmcdb1 ~]# powermt display dev=all

b) 使用udev持久化磁盘权限
# NOTE:How To Set Device Name Using UDEV on OL 7.X (文档 ID 2056427.1)
# 编辑rules规则文件
# 注意：rules文件中uuid区别大小写,
# 故要注意scsi_id -g -u -d $devnode 的输出结果。

c) 设置Disk I/O Scheduler on Linux
# 设置I/0 scheduler为[deadline]状态,共享使用
echo deadline > /sys/block/${ASM_DISK}/queue/scheduler
# 节点1执行展示结果,查看当前scheduler状态是否为[deadline]
[root@bmcdb1 ~]# cat /sys/block/emcpowera/queue/scheduler
noop [deadline] cfq
[root@bmcdb1 ~]# cat /sys/block/emcpowerb/queue/scheduler
noop [deadline] cfq
[root@bmcdb1 ~]# cat /sys/block/emcpowerc/queue/scheduler
noop [deadline] cfq
[root@bmcdb1 ~]# cat /sys/block/emcpowerd/queue/scheduler
noop [deadline] cfq
[root@bmcdb1 ~]# cat /sys/block/emcpowere/queue/scheduler
