2.实施步骤规划

  • 关闭所有crs资源,保留crs进程

  • 备份OCR

  • 修改 Public IP

  • 修改 VIP

  • 修改 tnsnames.ora 和 listener.ora

  • 修改 /etc/hosts

  • 修改操作系统IP

  • 重启crs及crs资源

  • 修改 local_listener

3.详细操作示例

3.1 关闭所有crs资源

因为修改Public IP和vip的命令均依赖于crs,所以修改修改Public IP和vip前需要关闭所有的crs资源,保留crs进程。

  • 首先查看集群状态

[root@node1 ~]# crs_stat -tName           Type           Target    State     Host        ------------------------------------------------------------ora.iesdb.db   application    ONLINE    ONLINE    node1       ora....b1.inst application    ONLINE    ONLINE    node1       ora....b2.inst application    ONLINE    ONLINE    node2       ora....srac.cs application    ONLINE    ONLINE    node2       ora....db1.srv application    ONLINE    ONLINE    node1       ora....db2.srv application    ONLINE    ONLINE    node2       ora....SM1.asm application    ONLINE    ONLINE    node1       ora....E1.lsnr application    ONLINE    ONLINE    node1       ora.node1.gsd  application    ONLINE    ONLINE    node1       ora.node1.ons  application    ONLINE    ONLINE    node1       ora.node1.vip  application    ONLINE    ONLINE    node1       ora....SM2.asm application    ONLINE    ONLINE    node2       ora....E2.lsnr application    ONLINE    ONLINE    node2       ora.node2.gsd  application    ONLINE    ONLINE    node2       ora.node2.ons  application    ONLINE    ONLINE    node2       ora.node2.vip  application    ONLINE    ONLINE    node2
  • 关闭所有的crs资源

oracle 用户登录节点1,依次执行以下命令:

[oracle@node1 ~]$ srvctl stop database -d iesdb [oracle@node1 ~]$ srvctl stop asm -n node1[oracle@node1 ~]$ srvctl stop asm -n node2[oracle@node1 ~]$ srvctl stop nodeapps -n node1[oracle@node1 ~]$ srvctl stop nodeapps -n node2

现在查看crs资源已经全部关闭:

[oracle@node1 ~]$ crs_stat -tName           Type           Target    State     Host        ------------------------------------------------------------ora.iesdb.db   application    OFFLINE   OFFLINE               ora....b1.inst application    OFFLINE   OFFLINE               ora....b2.inst application    OFFLINE   OFFLINE               ora....srac.cs application    OFFLINE   OFFLINE               ora....db1.srv application    OFFLINE   OFFLINE               ora....db2.srv application    OFFLINE   OFFLINE               ora....SM1.asm application    OFFLINE   OFFLINE               ora....E1.lsnr application    OFFLINE   OFFLINE               ora.node1.gsd  application    OFFLINE   OFFLINE               ora.node1.ons  application    OFFLINE   OFFLINE               ora.node1.vip  application    OFFLINE   OFFLINE               ora....SM2.asm application    OFFLINE   OFFLINE               ora....E2.lsnr application    OFFLINE   OFFLINE               ora.node2.gsd  application    OFFLINE   OFFLINE               ora.node2.ons  application    OFFLINE   OFFLINE               ora.node2.vip  application    OFFLINE   OFFLINE

3.2 备份OCR

OCR相当于Windows的注册表。对于Windows而言,所有的软件信息,用户,配置,安全等等统统都放到注册表里边。而集群呢,同样如此,所有和集群相关的资源,配置,节点,RAC数据库统统都放在这个仓库里。如果OCR被破坏则导致集群服务启动异常,需要修复OCR。因此OCR的管理与维护对于整个集群而言,是相当重要的。

OCR中通常包含下列内容

  • 节点成员信息

  • 数据库实例,节点,以及其他的映射关系

  • ASM

  • 资源配置信息(vip,services等等)

  • 服务特性(Service characteristics)

  • Oracle集群中相关进程的信息

  • CRS控制的第三方应用程序信息

这里进行OCR备份,主要是为了在oracle集群配置出错时能够通过OCR备份进行恢复。

root用户登录,只需在一个节点进行OCR备份即可:

# 首先创建备份文件夹[root@node1 ~]# mkdir /ocr_backup# ocr备份,备份文件任意后缀名均可[root@node1 ~]# ocrconfig -export /ocr_backup/ocr201706.bak

3.3 修改Public IP

如果将要修改的 Public IP 和原来的网段相同,则略过此步骤。

oracle用户登录:

# 查看当前状态[oracle@node1 ~]$ oifcfg getifeth0  192.168.56.0  global  publiceth2  10.1.1.0  global  cluster_interconnect# 删除Public IP配置信息[oracle@node1 ~]$ oifcfg delif -global eth0[oracle@node1 ~]$ oifcfg getifeth2  10.1.1.0  global  cluster_interconnect# 配置新的Public IP网段[oracle@node1 ~]$ oifcfg setif -global eth0/192.168.100.0:public[oracle@node1 ~]$ oifcfg getifeth0  192.168.100.0  global  publiceth2  10.1.1.0  global  cluster_interconnect# Public IP配置成功

3.4 修改VIP

root用户登录:

# 首先根据oracle用户的配置设置ORACLE_HOME变量[root@node1 ~]# export ORACLE_HOME="/oracle/product/10.2.0/db"#查看当前的VIP信息[root@node1 ~]# srvctl config nodeapps -n node1 -aVIP 已存在。: /node1-vip/192.168.56.98/255.255.255.0/eth0[root@node1 ~]# srvctl config nodeapps -n node2 -aVIP 已存在。: /node2-vip/192.168.56.99/255.255.255.0/eth0#修改VIP[root@node1 ~]# srvctl modify nodeapps -h用法: srvctl modify nodeapps -n  [-o ] [-A ]    -n            节点名    -A        节点级虚拟 IP 地址    -o     ORACLE_HOME 路径    -h                  打印用法[root@node1 ~]# srvctl modify nodeapps -n node1 -A 192.168.100.98/255.255.255.0/eth0[root@node1 ~]# srvctl modify nodeapps -n node2 -A 192.168.100.99/255.255.255.0/eth0#查看修改后的VIP[root@node1 ~]# srvctl config nodeapps -n node1 -aVIP 已存在。: /192.168.100.98/192.168.100.98/255.255.255.0/eth0[root@node1 ~]# srvctl config nodeapps -n node2 -aVIP 已存在。: /192.168.100.99/192.168.100.99/255.255.255.0/eth0# VIP 修改成功

3.5 修改 tnsnames.ora 和 listener.ora

oracle用户登录,所有节点均进行修改:

[oracle@node1 db]$ cd $ORACLE_HOME/network/admin# 修改前先进行文件备份[oracle@node1 admin]$ cp -a tnsnames.ora tnsnames.ora.bak[oracle@node1 admin]$ cp -a listener.ora listener.ora.bak

然后检查者两个文件,文件中Public IP和VIP为hostname的不做修改,文件中Public IP和VIP为IP地址的修改为新的Public IP和VIP。

示例:

# 将文件中的192.168.56.20修改为新的Public IP:192.168.100.20,# 文件中的node1-vip保持不变[oracle@node1 admin]$ cat listener.ora# listener.ora.node1 Network Configuration File: /oracle/product/10.2.0/db/network/admin/listener.ora.node1# Generated by Oracle configuration tools.SID_LIST_LISTENER_NODE1 =  (SID_LIST =    (SID_DESC =      (SID_NAME = PLSExtProc)      (ORACLE_HOME = /oracle/product/10.2.0/db)      (PROGRAM = extproc)    )  )LISTENER_NODE1 =  (DESCRIPTION_LIST =    (DESCRIPTION =      (ADDRESS = (PROTOCOL = TCP)(HOST = node1-vip)(PORT = 1521)(IP = FIRST))      (ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.100.20)(PORT = 1521)(IP = FIRST))    )  )

3.6 修改 /etc/hosts

root用户登录,所有节点均修改:

# 首先备份hosts文件[root@node1 admin]# cp -a /etc/hosts /etc/hosts.bak#查看当前hosts配置文件[root@node1 admin]# cat /etc/hosts# Do not remove the following line, or various programs# that require network functionality will fail.127.0.0.1               localhost.localdomain localhost::1             localhost6.localdomain6 localhost6192.168.56.20 node1192.168.56.21 node2192.168.56.98 node1-vip192.168.56.99 node2-vip10.1.1.1 node1-priv10.1.1.2 node2-priv

将其中的Public IP和VIP均修改为新的IP地址:

# 修改后的hosts文件[root@node1 admin]# cat /etc/hosts# Do not remove the following line, or various programs# that require network functionality will fail.127.0.0.1               localhost.localdomain localhost::1             localhost6.localdomain6 localhost6192.168.100.20 node1192.168.100.21 node2192.168.100.98 node1-vip192.168.100.99 node2-vip10.1.1.1 node1-priv10.1.1.2 node2-priv

3.7 修改操作系统IP

root用户登录,将所有节点的Public IP修改为新地址,然后重启网络服务:

[root@node1 ~]# cd /etc/sysconfig/network-scripts/[root@node1 network-scripts]# vim ifcfg-eth0 # Intel Corporation 82540EM Gigabit Ethernet ControllerDEVICE=eth0BOOTPROTO=noneONBOOT=yesHWADDR=08:00:27:b2:d1:1bNETMASK=255.255.255.0IPADDR=192.168.100.20TYPE=EthernetUSERCTL=noIPV6INIT=noPEERDNS=yes# 重启网络服务[root@node1 network-scripts]# service network restart

修改成功后,root用户登录,确保所有节点的Public IP和Private IP可以相互ping通。

3.8 重启crs及crs资源

root用户登录,所有节点均执行以下操作:

# 首先关闭CRS,(所有节点执行完该命令再继续下一步)[root@node1 ~]# crsctl stop crsStopping resources. This could take several minutes.Successfully stopped CRS resources.Stopping CSSD.Shutting down CSS daemon.Shutdown request successfully issued.# 开启CRS(所有节点)[root@node1 ~]# crsctl start crsAttempting to start CRS stack The CRS stack will be started shortly

稍等片刻,所有节点的crs资源均会正常启动:

[root@node1 ~]# crs_stat -tName           Type           Target    State     Host        ------------------------------------------------------------ora.iesdb.db   application    ONLINE    ONLINE    node1       ora....b1.inst application    ONLINE    ONLINE    node1       ora....b2.inst application    ONLINE    ONLINE    node2       ora....srac.cs application    ONLINE    ONLINE    node2       ora....db1.srv application    ONLINE    ONLINE    node1       ora....db2.srv application    ONLINE    ONLINE    node2       ora....SM1.asm application    ONLINE    ONLINE    node1       ora....E1.lsnr application    ONLINE    ONLINE    node1       ora.node1.gsd  application    ONLINE    ONLINE    node1       ora.node1.ons  application    ONLINE    ONLINE    node1       ora.node1.vip  application    ONLINE    ONLINE    node1       ora....SM2.asm application    ONLINE    ONLINE    node2       ora....E2.lsnr application    ONLINE    ONLINE    node2       ora.node2.gsd  application    ONLINE    ONLINE    node2       ora.node2.ons  application    ONLINE    ONLINE    node2       ora.node2.vip  application    ONLINE    ONLINE    node2

网络信息如下:

[root@node1 ~]# ifconfig eth0      Link encap:Ethernet  HWaddr 08:00:27:B2:D1:1B            inet addr:192.168.100.20  Bcast:192.168.100.255  Mask:255.255.255.0          UP BROADCAST RUNNING MULTICAST  MTU:1500  Metric:1          RX packets:8697 errors:0 dropped:0 overruns:0 frame:0          TX packets:28955 errors:0 dropped:0 overruns:0 carrier:0          collisions:0 txqueuelen:1000           RX bytes:788771 (770.2 KiB)  TX bytes:35854996 (34.1 MiB)eth0:1    Link encap:Ethernet  HWaddr 08:00:27:B2:D1:1B            inet addr:192.168.100.98  Bcast:192.168.100.255  Mask:255.255.255.0          UP BROADCAST RUNNING MULTICAST  MTU:1500  Metric:1eth2      Link encap:Ethernet  HWaddr 08:00:27:CB:6A:BB            inet addr:10.1.1.1  Bcast:10.1.1.255  Mask:255.255.255.0          UP BROADCAST RUNNING MULTICAST  MTU:1500  Metric:1          RX packets:322721 errors:0 dropped:0 overruns:0 frame:0          TX packets:283490 errors:0 dropped:0 overruns:0 carrier:0          collisions:0 txqueuelen:1000           RX bytes:198377998 (189.1 MiB)  TX bytes:145057008 (138.3 MiB)lo        Link encap:Local Loopback            inet addr:127.0.0.1  Mask:255.0.0.0          UP LOOPBACK RUNNING  MTU:16436  Metric:1          RX packets:110006 errors:0 dropped:0 overruns:0 frame:0          TX packets:110006 errors:0 dropped:0 overruns:0 carrier:0          collisions:0 txqueuelen:0           RX bytes:55092250 (52.5 MiB)  TX bytes:55092250 (52.5 MiB)

3.9 修改 local_listener

最后,还需要修改oracle的local_listener。

oracle 用户登录,只在一个节点操作即可:

注意:sql语句中的IP地址为新的VIP,如下:

ALTER SYSTEM SET LOCAL_LISTENER = '(ADDRESS = (PROTOCOL = TCP)(HOST =192.168.100.98)(PORT = 1521))' scope=both SID = 'iesdb1';

[root@node1 ~]# su - oracle[oracle@node1 ~]$ sqlplus / as sysdbaSQL*Plus: Release 10.2.0.5.0 - Production on Fri Jun 16 18:31:50 2017Copyright (c) 1982, 2010, Oracle.

至此,oracle rac的Public IP 和 VIP修改完毕。

4. 回退流程

如果我们中间修改出错,导致集群无法启动等,可以利用OCR回退至初始状态。

  • 首先在所有节点关闭crs

    root用户登录,在所有节点执行:

  [root@node1 ~]# crsctl stop crs  Stopping resources. This could take several minutes.  Successfully stopped CRS resources.  Stopping CSSD.  Shutting down CSS daemon.  Shutdown request successfully issued.
  • 还原所有节点的配置文件

  [root@node2 etc]# cp -a /etc/hosts.bak /etc/hosts  cp:是否覆盖"/etc/hosts"? y  # 2. 还原tnsnames.ora和listener.ora  [root@node2 admin]# cp -a tnsnames.ora.bak tnsnames.ora  cp:是否覆盖"tnsnames.ora"? y  [root@node2 admin]# cp -a listener.ora.bak listener.ora  cp:是否覆盖"listener.ora"? y  # 注意文件权限是否正确  [root@node2 admin]# ll tnsnames.ora  -rw-r--r-- 1 oracle oinstall 1878 06-16 10:21 tnsnames.ora  [root@node2 admin]# ll listener.ora  -rw-r--r-- 1 oracle oinstall 552 06-19 14:35 listener.or
  • 还原OCR

    root用户登录,只需在一个节点还原即可:

  # 最初备份的OCR文件为:  [root@node1 /]# ll /ocr_backup/ocr201706.bak   -rw-r--r-- 1 root root 107241 06-16 16:53 /ocr_backup/ocr201706.bak  # 还原OCR  [root@node1 /]# ocrconfig -import /ocr_backup/ocr201706.bak  # OCR还原成功后没有任何输出
  • 还原操作系统IP

  编辑/etc/sysconfig/network-scripts/目录下的网卡文件,将之前修改的网卡IP地址还原,然后重启网络服务。
  • 启动CRS,查看集群状态

    root用户登录,所有节点执行:

  [root@node1 ~]# crs_stat -t  Name           Type           Target    State     Host          ------------------------------------------------------------  ora.iesdb.db   application    ONLINE    ONLINE    node1         ora....b1.inst application    ONLINE    ONLINE    node1         ora....b2.inst application    ONLINE    ONLINE    node2         ora....srac.cs application    ONLINE    ONLINE    node2         ora....db1.srv application    ONLINE    ONLINE    node1         ora....db2.srv application    ONLINE    ONLINE    node2         ora....SM1.asm application    ONLINE    ONLINE    node1         ora....E1.lsnr application    ONLINE    ONLINE    node1         ora.node1.gsd  application    ONLINE    ONLINE    node1         ora.node1.ons  application    ONLINE    ONLINE    node1         ora.node1.vip  application    ONLINE    ONLINE    node1         ora....SM2.asm application    ONLINE    ONLINE    node2         ora....E2.lsnr application    ONLINE    ONLINE    node2         ora.node2.gsd  application    ONLINE    ONLINE    node2         ora.node2.ons  application    ONLINE    ONLINE    node2         ora.node2.vip  application    ONLINE    ONLINE    node2

此时可以看到CRS各资源都从处于ONLINE状态,最后,重新修改local_listener的IP为oracle VIP即可。

  • 修改local_listener

    orale用户,只在一个节点操作即可:

  [oracle@node1 ~]$ sqlplus / as sysdba  SQL*Plus: Release 10.2.0.5.0 - Production on Mon Jul 3 15:17:25 2017  Copyright (c) 1982, 2010, Oracle.  All Rights Reserved.

至此,oracle集群恢复完毕。

5. 修改private ip

这里补充下修改private ip的方法。

可以使用oracle用户来修改private ip,操作方法如下:

  • 修改心跳网段为10.10.10.0

    oracle用户登录,只在一个节点操作即可:

  # 查看当前的IP信息  [oracle@node1 ~]$ oifcfg  getif  eth0  192.168.56.0  global  public  eth2  10.1.1.0  global  cluster_interconnect  # 增加10.10.10.0网段为心跳网段  [oracle@node1 ~]$ oifcfg setif -global eth2/10.10.10.0:cluster_interconnect  [oracle@node1 ~]$ oifcfg  getif  eth0  192.168.56.0  global  public  eth2  10.1.1.0  global  cluster_interconnect  eth2  10.10.10.0  global  cluster_interconnect  # 删除原来的心跳网段  [oracle@node1 ~]$ oifcfg delif -global eth2/10.1.1.0  [oracle@node1 ~]$ oifcfg  getif  eth0  192.168.56.0  global  public  eth2  10.10.10.0  global  cluster_interconnect  # oifcfg帮助信息  [oracle@node1 ~]$ oifcfg -help  Name:      oifcfg - Oracle Interface Configuration Tool.  Usage:  oifcfg iflist [-p [-n]]      oifcfg setif {-node  | -global} {/:}...      oifcfg getif [-node  | -global] [ -if [/] [-type ] ]      oifcfg delif [-node  | -global] [[/]]      oifcfg [-help]       - name of the host, as known to a communications network        - name by which the interface is configured in the system         - subnet address of the interface        - type of the interface { cluster_interconnect | public | storage }
  • 关闭CRS

    root用户,所有节点均进行操作:

  [root@node1 ~]# crsctl stop crs  Stopping resources. This could take several minutes.  Successfully stopped CRS resources.  Stopping CSSD.  Shutting down CSS daemon.  Shutdown request successfully issued.
  • 修改/etc/hosts文件中的private ip内容

    root用户,所有节点均进行操作:

  # 修改前hosts文件  [root@node1 ~]# cat /etc/hosts  # Do not remove the following line, or various programs  # that require network functionality will fail.  127.0.0.1           localhost.localdomain localhost  ::1         localhost6.localdomain6 localhost6  192.168.56.20 node1  192.168.56.21 node2  192.168.56.98 node1-vip  192.168.56.99 node2-vip  10.1.1.1 node1-priv  10.1.1.2 node2-priv  # 修改后hosts文件  [root@node1 ~]# cat /etc/hosts  # Do not remove the following line, or various programs  # that require network functionality will fail.  127.0.0.1           localhost.localdomain localhost  ::1         localhost6.localdomain6 localhost6  192.168.56.20 node1  192.168.56.21 node2  192.168.56.98 node1-vip  192.168.56.99 node2-vip  10.10.10.1 node1-priv  10.10.10.2 node2-priv
  • 修改操作系统IP

    root用户,所有节点均操作:

  [root@node1 ~]# cat /etc/sysconfig/network-scripts/ifcfg-eth2  # Intel Corporation 82540EM Gigabit Ethernet Controller  DEVICE=eth2  BOOTPROTO=none  ONBOOT=yes  HWADDR=08:00:27:cb:6a:bb  TYPE=Ethernet  NETMASK=255.255.255.0  IPADDR=10.10.10.1  USERCTL=no  IPV6INIT=no  PEERDNS=yes  #重启网络服务  [root@node1 ~]# service network restart  [root@node1 ~]# ifconfig eth2  eth2      Link encap:Ethernet  HWaddr 08:00:27:CB:6A:BB              inet addr:10.10.10.1  Bcast:10.10.10.255  Mask:255.255.255.0            UP BROADCAST RUNNING MULTICAST  MTU:1500  Metric:1            RX packets:135852 errors:0 dropped:0 overruns:0 frame:0            TX packets:112129 errors:0 dropped:0 overruns:0 carrier:0            collisions:0 txqueuelen:1000             RX bytes:84007109 (80.1 MiB)  TX bytes:52783613 (50.3 MiB)  [root@node2 network-scripts]# ifconfig eth2  eth2      Link encap:Ethernet  HWaddr 08:00:27:F6:DB:67              inet addr:10.10.10.2  Bcast:10.10.10.255  Mask:255.255.255.0            UP BROADCAST RUNNING MULTICAST  MTU:1500  Metric:1            RX packets:112136 errors:0 dropped:0 overruns:0 frame:0            TX packets:135677 errors:0 dropped:0 overruns:0 carrier:0            collisions:0 txqueuelen:1000             RX bytes:52778410 (50.3 MiB)  TX bytes:83970669 (80.0 MiB)              # 保证所有节点的心跳可以相互ping通  [root@node1 ~]# ping 10.10.10.2  PING 10.10.10.2 (10.10.10.2) 56(84) bytes of data.  64 bytes from 10.10.10.2: icmp_seq=1 ttl=64 time=0.884 ms  64 bytes from 10.10.10.2: icmp_seq=2 ttl=64 time=0.206 ms
  • 启动CRS

    root用户,所有节点均操作:

  [root@node1 ~]# crsctl start crs  Attempting to start CRS stack   The CRS stack will be started shortly  [root@node1 ~]# crs_stat -t  Name           Type           Target    State     Host          ------------------------------------------------------------  ora.iesdb.db   application    ONLINE    ONLINE    node2         ora....b1.inst application    ONLINE    ONLINE    node1         ora....b2.inst application    ONLINE    ONLINE    node2         ora....srac.cs application    ONLINE    ONLINE    node2         ora....db1.srv application    ONLINE    ONLINE    node1         ora....db2.srv application    ONLINE    ONLINE    node2         ora....SM1.asm application    ONLINE    ONLINE    node1         ora....E1.lsnr application    ONLINE    ONLINE    node1         ora.node1.gsd  application    ONLINE    ONLINE    node1         ora.node1.ons  application    ONLINE    ONLINE    node1         ora.node1.vip  application    ONLINE    ONLINE    node1         ora....SM2.asm application    ONLINE    ONLINE    node2         ora....E2.lsnr application    ONLINE    ONLINE    node2         ora.node2.gsd  application    ONLINE    ONLINE    node2         ora.node2.ons  application    ONLINE    ONLINE    node2         ora.node2.vip  application    ONLINE    ONLINE    node2    [oracle@node1 ~]$ oifcfg getif  eth0  192.168.56.0  global  public  eth2  10.10.10.0  global  cluster_interconnect

至此,private ip修改完成,如果要进行回退工作,请参考"4.回退流程"。
