大家好，我是 JiekeXu,很高兴又和大家见面了,今天和大家聊聊 Oracle 19c RAC 安装遇到的坑，欢迎点击上方蓝字关注我，标星或置顶，更多干货第一时间到达！

虽说 Oracle 21C 马上要发布了，但 Oracle 19C 作为长期支持的大版本，才是很多企业和个人选择的主流，最近公司新上线的系统中均以 19C 为主，11204 已经逐渐退出了舞台。下面对 19C 的安装简单说明下，最主要的是介绍遇到的坑。

以下均以 Linuxone 操作系统下 SUSE 12 SP5 为例。

一、设置主机名：

# uname -a
Linux jiekesp5r1 4.12.14-120-default #1 SMP Thu Nov 7 16:39:09 UTC 2019 (fd9dc36) s390x s390x s390x GNU/Linux
--主机名原则上最好不要超过 8 位，小写字母加数字即可。
hostnamectl set-hostname jieksp5r1
hostnamectl set-hostname jieksp5r2

二、时区设置：

• 根据客户标准设置 OS 时区，国内通常为东八区"Asia/Shanghai".

• 在安装 GRID 之前，一定要先修改好 OS 时区，否则 GRID 将引用一个错误的 OS 时区，导致 DB 的时区，监听的时区等不正确。

jieksp5r1:/u01/app/19.0.0.0/grid #timedatectl status
     Local time: Mon 2021-03-01 21:20:16 CST
 Universal time: Mon 2021-03-01 13:20:16 UTC
       RTC time: n/a
      Time zone: Asia/Shanghai (CST, +0800)
 Network time on: no
NTP synchronized: no
 RTCin local TZ: no

修改OS时区：

# timedatectl set-timezone "Asia/Shanghai"

三、hosts 文件配置

在RAC的各个节点配置 /etc/hosts，注意不要修改localhost那一行。

# vi /etc/hosts
#public ip
192.168.1.XXX        jiekesp5r1
192.168.1.XXX        jiekesp5r2 
# private ip
10.10.41.XX   jiekesp5r1-priv
10.10.41.XX   jiekesp5r2-priv
# vip
192.168.1.XXX        jiekesp5r1-vip
192.168.1.XXX        jiekesp5r2-vip
# scan ip #安装时注意集群名不要超过 15 个字符，也不能有大写主机名。
192.168.1.XXX  jieke-cls-scan 

四、建立目录和权限

mkdir -p /u01/app/19.0.0.0/grid
mkdir -p /u01/app/grid
mkdir -p /u01/app/oracle/product/19.0.0.0/dbhome_1
chown -R grid:oinstall /u01
chown -R oracle:oinstall /u01/app/oracle
chmod -R 775 /u01

 五、建立用户和组

/usr/sbin/groupadd -g 1001 dba
/usr/sbin/groupadd -g 1000 oinstall
/usr/sbin/groupadd -g 1002 oper
/usr/sbin/groupadd -g 1010 asmadmin
/usr/sbin/groupadd -g 1011 asmdba
/usr/sbin/groupadd -g 1012 asmoper

/usr/sbin/useradd  -u 1000 -g oinstall -G oinstall,dba,oper,asmdba,asmadmin oracle -m -d /home/oracle
/usr/sbin/useradd  -u 1010 -g oinstall -G oinstall,dba,asmdba,asmadmin,asmoper grid  -m -d /home/grid

--修改用户密码
passwd  grid
passwd  oracle

六、环境变量

Grid:
more .bash_profile
umask 022
export ORACLE_BASE=/u01/app/grid
export ORACLE_HOME=/u01/app/19.0.0.0/grid
export ORACLE_SID=+ASM1
exportPATH=${ORACLE_HOME}/bin:${ORACLE_HOME}/OPatch:${PATH}
export HOST=`hostname | cut -f1-d"."`
export PS1='${HOST}:$PWD(${ORACLE_SID})$ '
export SSH_AUTH_SOCK=0

oracle:
more .bash_profile
umask 022
export ORACLE_BASE=/u01/app/oracle
exportORACLE_HOME=/u01/app/oracle/product/19.0.0.0/dbhome_1
export ORACLE_SID=JiekeXu1
#export NLS_LANG=AMERICAN_AMERICA.ZHS16GBK
export NLS_LANG=AMERICAN_AMERICA.AL32UTF8
export NLS_DATE_FORMAT="YYYY-MM-DDHH24:MI:SS"
export LD_LIBRARY_PATH=${ORACLE_HOME}/lib
exportPATH=${ORACLE_HOME}/bin:${ORACLE_HOME}/OPatch:${PATH}
export HOST=`hostname | cut -f1-d"."`
export PS1='${HOST}:$PWD(${ORACLE_SID})$ '

 七、用户 shell limits 配置 

# vi /etc/security/limits.conf
*               soft    stack    unlimited
*               hard    stack    unlimited
*               soft    nproc    unlimited
*               hard    nproc    unlimited
*               soft    nofile   1048576
*               hard    nofile   1048576
*               soft    memlock  unlimited
*               hard    memlock  unlimited

八、内核参数配置

编辑/etc/sysctl.conf文件，需要增加或修改的内容如下：
#示例如下： 
vi /etc/sysctl.conf
fs.aio-max-nr = 3145728
fs.file-max = 6815744
kernel.shmall = 20971520
kernel.shmmax = 85899345920
kernel.shmmni = 4096
kernel.shmmax = 68719476736        # Controls the maximum shared segmentsize, in bytes
kernel.shmall = 1073741824              # Controls themaximum number of
kernel.sem = 10240 335534080 10240 32767
kernel.panic_on_oops = 1
kernel.numa_balancing= 0
kernel.pid_max = 131072
net.ipv4.ip_local_port_range = 9000 65500
net.core.rmem_default = 4194304
net.core.rmem_max = 4194304
net.core.wmem_default = 1048576
net.core.wmem_max = 1048576
vm.min_free_kbytes= 1048576   #固定值：32G内存2G，64G 内存 5G=5242880 128G 内存 10G
vm.hugetlb_shm_group =1000  
vm.nr_hugepages =内存K/3/Hugepagesize
#操作系统内存的1/3 ，如果是 x86 Hugepagesize =2048，linuxone=1024
# 例x86平台64G内存  64*1024*1024/3/2048=10922
#linuxone平台64G内存  64*1024*1024/3/1024=21845
net.ipv4.ipfrag_low_thresh=15728640
net.ipv4.ipfrag_high_thresh=16777216
kernel.msgmnb = 6553600  #该文件指定在一个消息队列中最大的字节数
kernel.msgmax = 65535  #该文件指定了从一个进程发送到另一个进程的消息最大长度。进程间的消息传递是在内核的内存中进行的。不会交换到硬盘上。所以如果增加该值，则将增加操作系统所使用的内存数量。
kernel.msgmni = 2878  #该文件指定消息队列标识的最大数目。缺省设置：16。
net.ipv4.ip_forward = 0    #Controls IP packet forwarding
net.ipv4.conf.default.rp_filter = 0       #Controls source route verification
net.ipv4.conf.default.accept_source_route =0  #Do not accept source routing
net.ipv4.tcp_syncookies = 1    # Controls the use of TCP syncookie
kernel.core_uses_pid = 1  # Controls whether core dumps will append thePID to the core filename, Useful for debugging multi-threaded applications        
使参数生效
# sysctl –p

九、共享磁盘情况

要求归档和数据的磁盘来自不同的存储，属组：grid:asmadmin；权限：660
OCR 盘 3 块，每块 5GB， Normal 格式。 
归档盘或者数据盘 100G 以上，按照实际需求划分，每块盘大小需一致，Extend 格式。

jiekesp5r1:/u01/app/19.0.0.0/grid #lvmdiskscan
 /dev/mapper/3600507680c800576f8000000000007bd-part1 [       1.00 GiB]
 /dev/mapper/3600507680c800576f8000000000007bd-part2 [      32.00 GiB]

  6partitions
  0LVM physical volume whole disks
  1LVM physical volume

接下来需要检查内存、swap、关闭透明大页、关闭防火墙和 selinux 等一些操作，这里就先不说明了。最后一项配置互信，便可以开启图形化安装 GI 了，这里着重说明一下配置互信。

十、配置互信

以前都是不知道用户密码，使用 ssh-keygen 配置，一路回车，将自己的公钥写入对方对应用户的 ~/.ssh/authorized_keys 即可。

cat id_rsa.pub >> authorized_keys 比较方便快捷。

后期知道用户密码一般都是使用图形化 第四步 SSH connectivity  时输入 grid 用户密码，点击 setup 配置，点击 test 测试连接。

这次使用以上两种方法配置居然都没有测试通过，报错 INS-06006，然后使用第三种方法 oracle 自带脚本 sshUserSetup.sh 配置。

（1）配置步骤如下：

cd .ssh
rm -rf *
/u01/app/19.0.0.0/grid/oui/prov/resources/scripts/sshUserSetup.sh-user grid -hosts "jiekesp5r1 jiekesp5r2"-advanced -confirm –noPromptPassphrase

for h in jiekesp5r1 jiekesp5r1-priv jiekesp5r2 jiekesp5r2-priv;do
ssh -l grid -o StrictHostKeyChecking=no $h date;
done

/u01/app/19.0.0.0/grid/oui/prov/resources/scripts/sshUserSetup.sh-user oracle -hosts "jiekesp5r1 jiekesp5r2"-advanced -confirm -noPromptPassphrase

for h in jiekesp5r1 jiekesp5r1-priv jiekesp5r2 jiekesp5r2-priv;do
ssh -l oracle -o StrictHostKeyChecking=no $h date;
done

（2）INS-06006

下一步也会报错：

没办法，明明已经配置好 ssh 了，测试没问题但就是图形化点击 test 就报错 INS-06006 ，真是活见鬼了。尝试过很多办法无果最后在 mos 上找到一篇 “ID2555697.1” INS-06006 GI RunInstaller Fails If OpenSSH Is Upgradedto 8.x (文档 ID2555697.1) 说是 OpenSSH  版本升级到 8.0 的问题，注意到说明 SUSE12SP4 OpenSSH_7.2 会有这个问题，AIX OpenSSH_7.5 也会有这个问题。

jiekesp5r1:/u01/app/19.0.0.0/grid(+ASM1)>ssh-V
OpenSSH_7.2p2, OpenSSL 1.0.2p-fips  14 Aug 2018

上图英文被水印遮挡住了一部分，这里翻译如下： 

为了降低(CVE-2019-6111)的风险，OpenSSH 8.0增加了客户端检查从服务器发送的文件名是否匹配命令行请求，如果客户端和服务器通配符扩展存在差异，客户端可能会拒绝从服务器发送的文件。由于这个原因，OpenSSH 8.0 为scp提供了一个新的“-T”标志，该标志禁用这些客户端检查。详情请参见https://www.openssh.com/txt/release-8.0

--使用 debug 模式
sh gridSetup.sh -debug | tee /tmp/gridsetup.log
Errors  :
    PRVG-2019 : Check for equivalence of user"grid" from node "jiekesp5r1" to node "jiekesp5r2"failed

PRKN-1038: The command "/usr/bin/ssh -o FallBackToRsh=no  -o PasswordAuthentication=no  -o StrictHostKeyChecking=yes  -o NumberOfPasswordPrompts=0  jiekesp5r2 -n /bin/true" run on node
 "jiekesp5r1" gave an unexpected output:"sign_and_send_pubkey: signing failed: agent refused operationPermissiondenied (publickey,keyboard-interactive)."

SOLUTION
Workaround : (if your unix admin allows it)

Before installation, as root user: (pleasechange the path if the location of your "scp" is not the same withbelow)

（3）SOLUTION 解决办法

# Rename the original scp.
mv /usr/bin/scp /usr/bin/scp.orig

# Create a new file </usr/bin/scp>.
vi /usr/bin/scp

# Add the below line to the new createdfile </usr/bin/scp>.
/usr/bin/scp.orig -T $*

# Change the file permission.
chmod 555 /usr/bin/scp

Afterinstallation:

mv /usr/bin/scp.orig /usr/bin/scp

十一、解决 ssh 问题 

jiekesp5r1:/etc# cd /usr/bin
jiekesp5r1:/usr/bin# ll scp*
-rwxr-xr-x1 root root 100592 Jul 18  2019 scp
-rwxr-xr-x1 root root     90 Oct 26  2016 scp-dbus-service
jiekesp5r1:/usr/bin# mv /usr/bin/scp /usr/bin/scp.orig
jiekesp5r1:/usr/bin# ll scp*
-rwxr-xr-x1 root root     90 Oct 26  2016 scp-dbus-service
-rwxr-xr-x1 root root 100592 Jul 18  2019 scp.orig
jiekesp5r1:/usr/bin# vi /usr/bin/scp

/usr/bin/scp.orig-T $*
jiekesp5r1:/usr/bin# chmod 555 /usr/bin/scp
jiekesp5r1:/usr/bin# ll scp*
-r-xr-xr-x1 root root     24 Mar  1 14:48 scp
-rwxr-xr-x1 root root     90 Oct 26  2016 scp-dbus-service
-rwxr-xr-x1 root root 100592 Jul 18  2019 scp.orig 

以上配置好之后退出图形化重新 runInstaller 还会有问题，再需要根据 ID：2070270.1 配置一个环境变量 export SSH_AUTH_SOCK=0 然后使用新的 VNC 界面重新安装。GI runInstaller Fails with INS-6006 in VNC During SSH testeven though SSH Setup is successful (文档 ID 2070270.1)

这样算是解决了，不过有的时候只需要修改 SCP 即可，不需要配置 SSH_AUTH_SOCK 便可以测试通过，这个看当时的环境决定啦，下面还有一个问题需要说明一下。

十二、集群名问题

这里的 SCAN Name 便是 /etc/hosts 文件里指定的名字，必须一模一样，由于业务命名规范类似于  JiekeXu-cls-scan 这样的集群名字超过 15 个字符便写到了下方栏目中，这样也能进行下一步，不会报错，但是当执行 root.sh 脚本时便出现了问题。

注意：

• cluster name长度要小于等于15个字符，可以使用字母，数字和短横线(-)，并以字母开头。

• 建议统一使用小写字母，切勿大小写字母混合使用。

• scan name为/etc/hosts中配置的scan ip的别名。
