0、参数准备

1、HostName、ClusterName、ScanName

2、IP（Public，Private，Virtual，Scan）

3、ASMDISK（OCR，ARCH，DATA；Redundancy）

4、ORACLE_SID

5、User Password（root，oracle，grid）

6、CharacterSet（CharacterSet，NationalCharacterSet）

7、Software（ORACLE，GRID，REDHAT）

8、ISCDB

一、环境检查

2、Kernel Info

uname -r

3、CPU Info

grep "model name" /proc/cpuinfo grep "model name" /proc/cpuinfo | wc -l

4、Memory Info

##查看内存条数、大小 dmidecode|grep -P -A5 "Memory\s+Device"|grep Size|grep -v Range grep MemTotal /proc/meminfo | awk '{print $2}'

2、Configuring Kernel Parameters for Linux

The /etc/sysctl.conf file has been deprecated

/etc/sysctl.conf文件在OL7和RHEL7中已被弃用

cat <> /etc/sysctl.d/97-oracledatabase-sysctl.conf fs.aio-max-nr = 1048576 fs.file-max = 6815744 kernel.shmall = 2097152 ##equal SGA，mininum is 2097152,advise 40 percent of the size ofphysical memory in pages kernel.shmmax = 4294967295 ##advise Half the size of physical memory in bytes 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 net.ipv4.conf.eno5.rp_filter = 2 net.ipv4.conf.eno6.rp_filter = 2 EOF

3、Resource Limits

4、USER CREATE

Creating the OSASM Group # groupadd -g 54329 asmadmin Creating the OSDBA for ASM Group # /usr/sbin/groupadd -g 54327 asmdba Creating the OSOPER for ASM Group # /usr/sbin/groupadd -g 54328 asmoper Creating the OSDBA Group for Database Installations # /usr/sbin/groupadd -g 54322 dba Creating an OSOPER Group for Database Installations # groupadd -g 54323 oper Creating the OSBACKUPDBA Group for Database Installations # /usr/sbin/groupadd -g 54324 backupdba Creating the OSDGDBA Group for Database Installations # /usr/sbin/groupadd -g 54325 dgdba Creating the OSKMDBA Group for Database Installations # /usr/sbin/groupadd -g 54326 kmdba Creating the OSRACDBA Group for Database Installations # /usr/sbin/groupadd -g 54330 racdba $ id oracle uid=54321(oracle) gid=54321(oinstall) groups=54321(oinstall),54322(dba),54323(oper),54324(backupdba),54325(dgdba),54326(kmdba),54327(asmdba),54330(racdba) $ id grid uid=54331(grid) gid=54321(oinstall) groups=54321(oinstall),54322(dba),54327(asmdba),54328(asmoper),54329(asmadmin),54330(racdba)

##创建用户组 /usr/sbin/groupadd -g 54321 oinstall /usr/sbin/groupadd -g 54322 dba /usr/sbin/groupadd -g 54323 oper /usr/sbin/groupadd -g 54324 backupdba /usr/sbin/groupadd -g 54325 dgdba /usr/sbin/groupadd -g 54326 kmdba /usr/sbin/groupadd -g 54327 asmdba /usr/sbin/groupadd -g 54328 asmoper /usr/sbin/groupadd -g 54329 asmadmin /usr/sbin/groupadd -g 54330 racdba ##创建用户 /usr/sbin/useradd -u 54321 -g oinstall -G dba,asmdba,backupdba,dgdba,kmdba,racdba oracle /usr/sbin/useradd -u 54331 -g oinstall -G asmadmin,asmdba,asmoper,oper,dba grid #修改密码，这边密码均设置为oracle,密码可以按自己需要修改 echo "oracle" |passwd grid --stdin echo "oracle" |passwd oracle --stdin

5、Oracle Home and Oracle Base Directory CREATE

mkdir -p /u01/app/grid mkdir -p /u01/app/12.2.0/grid mkdir -p /u01/app/oracle/product/12.2.0/db mkdir -p /u01/app/oraInventory chown -R grid:oinstall /u01/app/grid chown -R grid:oinstall /u01/app/12.2.0 chown -R grid:oinstall /u01/app/oraInventory chown -R oracle:oinstall /u01/app/oracle chmod -R 775 /u01

6、Disable Firewalld and SELLINUX

--关闭防火墙 systemctl stop firewalld systemctl disable firewalld --关闭selinux sed -i 's/SELINUX=enforcing/SELINUX=disabled/g' /etc/selinux/config

7、HOSTS

cat >> /etc/hosts <

8、Disable Transparent Hugepages & NUMA

For example, for Oracle Linux 7.3, the procedure to disable Transparent HugePages involves editing the /etc/default/grub file and then running the command grub2-mkconfig

sed -i 's/quiet/quiet transparent_hugepage=never numa=off/' /etc/default/grub ##重建grub 配置文件： ##fdisk -l可以查看主分区的Disk label type: gpt ##MBR 分区表 ##grub2-mkconfig -o /etc/grub2.cfg\ ##efi 引导模式,efi+GPT分区表 grub2-mkconfig -o /etc/grub2-efi.cfg ##reboot之后查看是否生效 numactl --hardware dmesg|grep -i numa cat /proc/cmdline ##临时生效 echo never >/sys/kernel/mm/transparent_hugepage/enabled echo never >/sys/kernel/mm/transparent_hugepage/defrag

9、Disable NOZEROCONF

echo "NOZEROCONF=yes" >> /etc/sysconfig/network

10、Disable NetworkManager

systemctl stop NetworkManager.service systemctl disable NetworkManager.service

11、Disable avahi-daemon

systemctl stop avahi-daemon.socket systemctl stop avahi-daemon.service systemctl disable avahi-daemon.service ps -ef|grep avahi-daemon

12、Disable chronyd

By default, the NTP service available on Oracle Linux 7 and Red Hat Linux 7 is chronyd and the NTP service available on Oracle Linux 6 and Red Hat Linux 6 or lower is ntpd.

systemctl stop chronyd systemctl disable chronyd mv /etc/resolv.conf /etc/resolv.conf.bak mv /etc/chrony.conf /etc/chrony.conf.bak

13、配置/dev/shm

cat <> /etc/fstab tmpfs /dev/shm tmpfs size=4G 0 0 EOF mount -o remount /dev/shm

14、UDEV+MULTIPATH

##安装multipath yum install -y device-mapper* mpathconf --enable --with_multipathd y ##查看磁盘wwid /usr/lib/udev/scsi_id -g -u /dev/sdb --配置multipath.confc cat <> /etc/multipath.conf defaults { user_friendly_names yes } blacklist { devnode "^sda" } multipaths { multipath { wwid "36000c299c61a189afae17172197fd20e" alias asm_OCR } multipath { wwid "36000c29511ad8bc6c69c3d63a8f4e6c8" alias asm_DATA } } EOF --获取ENV{DM_UUID} cd /dev/mapper >udev_info for i in `ls asm*`; do printf "%s %s\n" "$i" "$(udevadm info --query=all --name=/dev/mapper/$i |grep -i dm_uuid)">>udev_info; done --配置udev规则文件、99-oracle-asmdevices.rules文件(复制到节点二) cat /dev/mapper/udev_info |while read line do dm_uuid=`echo $line |awk -F'=' '{print $2}'`; disk_name=`echo $line|awk '{print $1}'`; echo "KERNEL==\"dm-*\",ENV{DM_UUID}==\"${dm_uuid}\",SYMLINK+=\"asmdisks/${disk_name}\",OWNER=\"grid\",GROUP=\"asmadmin\",MODE=\"0660\"">>/etc/udev/rules.d/99-oracle-asmdevices.rules done --启动udev服务 udevadm control --reload-rules udevadm trigger --查看udev绑盘是否成功 ls -l /dev/asmdisks/*

15、环境变量设置
