    • 配置GI
    • root.sh脚本调试

    GI的安装

    我们选择的版本是Oracle Grid Infrastructure 11g Release 2 (11.2.0.３.0) for Linux x86-64
    下载，解压完毕，通过VMWare的共享实现对安装文件的访问。

    [grid@racnode1 grid]$ cd /mnt/hgfs/grid/
[grid@racnode1 grid]$ pwd
/mnt/hgfs/grid
[grid@racnode1 grid]$ ls
doc  install  readme.html  response  rpm  runcluvfy.sh  runInstaller  sshsetup  stage  welcome.html

    切换root用户，先安装cvuqdisk包。

    [grid@racnode1 rpm]$ su
Password: 
[root@racnode1 rpm]# rpm -ivh ./cvuqdisk-1.0.9-1.rpm 
Preparing...                          ################################# [100%]
        file /usr/sbin/cvuqdisk from install of cvuqdisk-1.0.9-1.x86_64 conflicts with file from package cvuqdisk-1.0.7-1.x86_64

    安装前准备工作：

    安装前，我们先进行集群安装前的检查工作。执行脚本runcluvfy.sh.

    [grid@racnode1 grid]$ ./runcluvfy.sh stage -pre crsinst -n racnode1,racnode2 -fixup -verbose

    检查完，有几处有提示的。

    • shmmax配置偏小。
    Check: Kernel parameter for "shmmax"
  Node Name         Current       Configured    Required      Status        Comment
  ----------------  ------------  ------------  ------------  ------------  ------------

Result: Kernel parameter check failed for "shmmax"

    修改 /etc/sysctl.conf中的kernel.shmmax为推荐值。

    • -elfutils-libelf-devel安装了x86_64和 i686两个包。
    Check: Package existence for "elfutils-libelf-devel"
  Node Name     Available                 Required                  Status

  racnode1      elfutils-libelf-devel-0.172-2.el7  elfutils-libelf-devel-0.97  passed

WARNING:
PRVF-7584 : Multiple versions of package "elfutils-libelf-devel" found on node racnode1: elfutils-libelf-devel(x86_64)-0.172-2.el7,elfutils-libelf-devel(i686)-0.172-2.el7
Result: Package existence check passed for "elfutils-libelf-devel"

    这个我们可以卸载一个i686的包。不管它也可以。

    [root@racnode1 ~]# rpm -qa |grep elfutils-libelf-devel
elfutils-libelf-devel-0.172-2.el7.x86_64

    OL6和 OL7 都没有pdksh了。我们去OL5下载一个安装上。

    [root@racnode1 ~]# wget http://yum.oracle.com/repo/OracleLinux/OL5/latest/x86_64                                                       /getPackage/pdksh-5.2.14-37.el5_8.1.x86_64.rpm

    • unreachable node的DNS响应没有通过

    这个是一个bug，OL5系统里面nslookup 查找一个域名超时，返回码是0，OL6和OL7查找一个域名超时时，返回是1.所以这里校验脚本无法正确识别这种情况。我们可以修复它，也可以忽略它。

    Checking the file "/etc/resolv.conf" to make sure only one of domain and search entries is defined

PRVF-5637 : DNS response time could not be checked on following nodes: racnode2,racnod1

    我们试图修复下该bug:

    [grid@racnode1 grid]$ mv /bin/nslookup /bin/nslookup.origin
[grid@racnode1 grid]$ vim /bin/nslookup
[grid@racnode1 grid]$ cat /bin/nslookup
#!/bin/bash
HOSTNAME=${1}
/bin/nslookup.origin $HOSTNAME
exit 0

    看看效果：

The DNS response time for an unreachable node is within acceptable limit on all nodes

File "/etc/resolv.conf" is consistent across nodes

    没有问题了。

    正式进入安装阶段

    - 安装GI软件

    切换，进入X window模式。

    [grid@racnode1 ~]$ xrdb .Xresources

    • 第一步：选择安装内容。


      image.png

    • 第二步：略过update，下一步。


      image.png

    • 第三步：语言选择，英语就够了。


      image.png

    • 第四步：用户组和管理脚色的选择。


      image.png

    • 第五步：ORACLE-BASE和ORACLE-HOME的选择，我们在环境变量中配置了。保持不变。


      image.png

    • 第六步：安装仓库选择。保持不变。


      image.png

    • 第七步：前置条件检查。


      image.png

      这里提示需要ksh了。不需要pdksh了。按照前面包的提示安装，我们卸载掉pdksh，在安装一次ksh，点击Check Again。通过。

    • 第八步：安装软件开始。


      image.png

    • 第九步：需要用root用户执行脚本了。


      image.png

    orainstRoot.sh脚本

    [root@racnode1 ~]# /u01/app/oraInventory/orainstRoot.sh
Changing permissions of /u01/app/oraInventory.
Adding read,write permissions for group.
Removing read,write,execute permissions for world.

Changing groupname of /u01/app/oraInventory to oinstall.
The execution of the script is complete.

    root.sh脚本

    [root@racnode1 ~]# /u01/app/11.2.0/grid/root.sh
Performing root user operation for Oracle 11g

The following environment variables are set as:
    ORACLE_OWNER= grid
    ORACLE_HOME=  /u01/app/11.2.0/grid

Enter the full pathname of the local bin directory: [/usr/local/bin]:
   Copying dbhome to /usr/local/bin ...
   Copying oraenv to /usr/local/bin ...
   Copying coraenv to /usr/local/bin ...

Entries will be added to the /etc/oratab file as needed by
Database Configuration Assistant when a database is created
Finished running generic part of root script.
Now product-specific root actions will be performed.

To configure Grid Infrastructure for a Stand-Alone Server run the following command as the root user:
/u01/app/11.2.0/grid/perl/bin/perl -I/u01/app/11.2.0/grid/perl/lib -I/u01/app/11.2.0/grid/crs/install /u01/app/11.2.0/grid/crs/install/roothas.pl


To configure Grid Infrastructure for a Cluster execute the following command:
/u01/app/11.2.0/grid/crs/config/config.sh
This command launches the Grid Infrastructure Configuration Wizard. The wizard also supports silent operation, and the parameters can be passed through the response file that is available in the installation media.

    节点1安装完毕。同样的步骤在节点2上面安装GI。

    - 配置我们的集群服务器。

    我们要配置的是集群，所以直接执行以下配置脚本。

    [grid@racnode1 grid]$ /u01/app/11.2.0/grid/crs/config/config.sh

    • 第一步：选择配置GI。


      image.png

    • 第二部：填写配置信息。


      image.png

      这里图是旧的，我们不要选择GNS，我们将SCAN Name命名为racnode-cluster-scan.cluster.org

    • 第三步：添加第二个节点到集群中，输入口令，点击setup，检验节点组件ssh的连通性。


      image.png
      image.png

      成功进入下一步。

    • 第四步：选择公网和私网的适配器。


      image.png

    • 第五步：选择OCR和VF的存储类型，我们选择ASM。


      image.png

    • 第六步：选择Disk Group，新装系统我们选择Create。


      image.png

    • 第七步：按照事前规划，选择ORCL:CRS，创建crs磁盘组。


      image.png

      注：这里图示有错误。

    • 第八步：简化管理，我们输入统一口令。


      image.png

    • 第九步：略过IPM安装。


      image.png

    • 第十步：完成基本配置，开始配置安装。


      image.png
    - 第十一步：执行root.sh脚本
    image.png
    • root.sh脚本的错误调试过程
      创建crs时，如果失败，会出现错误提示：
    [root@racnode1 ~]# /u01/app/11.2.0/grid/root.sh

The following environment variables are set as:
   ORACLE_OWNER= grid

    出现错误后，我们需要卸载掉刚才的过程，我们会运行rootcrs.pl -deconfig -force -verbose脚本。

    重新配置系列的文件，这步可能会有报错。

    [root@racnode1 ~]# /u01/app/11.2.0/grid/crs/install/rootcrs.pl -deconfig -force -verbose

    我们需要安装perl的这个模块

    [root@racnode1 tmp]# yum install perl-Env

    再次卸载掉配置。

    [root@racnode1 ~]# /u01/app/11.2.0/grid/crs/install/rootcrs.pl -deconfig -force -verbose

    再次执行root.sh

    节点还是显示有错误

    一般来讲，可能是11g中的一个bug。ohasd无法启动。
    我们看看进程情况，然后跟踪下进程停在什么地方。

    [root@racnode2 bin]# ps -ef|grep oha
root      19899      1  0 12:39 ?        00:00:00 /u01/app/11.2.0/grid/bin/ohasd.bin reboot

[root@racnode2 bin]# strace -p 19899 -o hem.log
strace: Process 19899 attached

    开启另一个窗口，杀掉该进程。然后看看结果。

    [root@racnode2 bin]#
[root@racnode2 bin]# tail hem.log
stat("/u01/app/11.2.0/grid/log/racnode2/ohasd/ohasd.log", {st_mode=S_IFREG|0644, st_size=522008, ...}) = 0

stat("/u01/app/11.2.0/grid/log/racnode2/ohasd/ohasd.log", {st_mode=S_IFREG|0644, st_size=522008, ...}) = 0

write(1, "Timed out waiting for init.ohasd"..., 67) = 67
open("/var/tmp/.oracle/npohasd", O_WRONLY <unfinished ...>
+++ killed by SIGKILL +++

    果然停止在/var/tmp/.oracle/npohasd这个地方。解决办法是在重新运行root.sh脚本同时，开启另一个窗口，运行下面命令。

    [root@racnode2 bin]# dd if=/var/tmp/.oracle/npohasd of=/dev/null bs=1024 count=1
^C0+0 records in
0+0 records out
0 bytes (0 B) copied, 1.70967 s, 0.0 kB/s

    再次启动root.sh脚本，过程顺利了。没有报错了。关闭上面的窗口中的dd命令。

OLR initialization - successful
Adding Clusterware entries to inittab
CRS-2672: Attempting to start 'ora.mdnsd' on 'racnode1'

    执行root.sh这个步骤要保证两台节点的root.sh脚本执行正确。再接着进行下面的步骤。root.sh成功完成的提示如下：

    clscfg: -install mode specified

    • 第十二步：配置完成后的检查。
      如果安装在Oracle Cluster Verification Utility 阶段报错，我们可以看看日志问题在哪里。
      我们这次安装就提示错误，没有通过Verification。查看日志。

    racnode-cluster-scan.cluster.org的域名解析没有通过。如果没有配置域名服务器，我们就采用权宜之计，修改下nslookup内容。

    [root@racnode1 crsconfig]# cat /bin/nslookup
#!/bin/bash
HOSTNAME=${1}
if [ $HOSTNAME = "racnode-cluster-scan.cluster.org" ];then
 echo "Server:         192.168.1.1"
 echo "Address:        192.168.1.1#53"
 echo "Non-authoritative answer:"
 echo "Name:   racnode-cluster-scan.cluster.org"
 echo "Address: 192.168.1.22"
else
 /bin/nslookup.origin $HOSTNAME
fi
exit 0
[root@racnode1 crsconfig]# nslookup racnode-cluster-scan.cluster.org
Server:         192.168.1.1
Address:        192.168.1.1#53
Non-authoritative answer:
Name:   racnode-cluster-scan.cluster.org
Address: 192.168.1.22
[root@racnode1 crsconfig]#

    retry一下最后一步，再跟踪下日志，没有报错了。

    Jun 8, 2019 2:01:44 PM oracle.install.commons.util.LogStream log
INFO: TCP connectivity to SCAN Listeners exists on all cluster nodes

Jun 8, 2019 2:01:44 PM oracle.install.commons.util.LogStream log

    root.sh这个脚本执行的内容较多，干扰多，出错的地方也比较多，出错的原因也是各种各样的。如果出错了，通过日志检查原因，修正错误，卸载掉配置，再重新运行root.sh脚本。

    /u01/app/11.2.0/grid/crs/install/rootcrs.pl -deconfig -force -verbose

    至此GI配置成功。

    检查下集群状态：

    [grid@racnode1 ~]$ crsctl check crs
CRS-4638: Oracle High Availability Services is online
CRS-4537: Cluster Ready Services is online
CRS-4529: Cluster Synchronization Services is online
CRS-4533: Event Manager is online
[grid@racnode1 ~]$

    没有问题。

    下一节，我们安装Oracle数据库。
