变更目标 ip类型 节点 原IP 目标IP PUBLIC IP racdb01 192.168.2.60 192.168.2.160 racdb02 192.168.2.62 192.168.2.162 VIP racdb01 192.168.2.61 192.168.2.161 racdb02 192.168.2.63 192.168.2.163 SCAN-IP racdb01 racdb02 192.168.2.64 192.168.2.164 生产环境做变更对核心文件需要进行备份
gpnp备份
两个节点都要操作
GRIDcd $ORACLE_HOMEgpnp/profiles/peer/cp profile.xml profile.xml.bak
修改任意IP前需对/etc/hosts文件进行修改不再赘述。 一、修改puclib ip
1.1 查看当前配置
GRID[gridracdb01 ~]$ oifcfg getif
ens33 192.168.2.0 global public
ens36 10.10.10.0 global cluster_interconnect,asm 1.2 查看当前网卡
ens38是我们新指定的PUBLIC网卡
一节点
ens38: flags4163UP,BROADCAST,RUNNING,MULTICAST mtu 1500inet 192.168.2.160 netmask 255.255.255.0 broadcast 192.168.2.255
二节点 ens38: flags4163UP,BROADCAST,RUNNING,MULTICAST mtu 1500inet 192.168.2.162 netmask 255.255.255.0 broadcast 192.168.2.255 1.3 删除原公网配置
GRIDoifcfg delif -global ens33/192.168.2.0
1.4 添加公网配置
示例 oifcfg setif -global 私有网卡名/新私有网段:cluster_interconnect,asmoifcfg setif -global ens38/192.168.2.0:public
1.5 检查
[gridracdb01 ~]$ oifcfg getif
ens36 10.10.10.0 global cluster_interconnect,asm
ens38 192.168.2.0 global public 二、变更VIP
2.1 查看当前VIP配置
GRID[gridracdb02 ~]$ srvctl config nodeapps -a
Network 1 exists
Subnet IPv4: 192.168.2.0/255.255.255.0/ens33, static
Subnet IPv6:
Ping Targets:
Network is enabled
Network is individually enabled on nodes:
Network is individually disabled on nodes:
VIP exists: network number 1, hosting node racdb01
VIP Name: racdb01-vip
VIP IPv4 Address: 192.168.2.61
VIP IPv6 Address:
VIP is enabled.
VIP is individually enabled on nodes:
VIP is individually disabled on nodes:
VIP exists: network number 1, hosting node racdb02
VIP Name: racdb02-vip
VIP IPv4 Address: 192.168.2.63
VIP IPv6 Address:
VIP is enabled.
VIP is individually enabled on nodes:
VIP is individually disabled on nodes:
2.2 查看当前监听地址
GRID[gridracdb02 ~]$ lsnrctl status
Listening Endpoints Summary...(DESCRIPTION(ADDRESS(PROTOCOLipc)(KEYLISTENER)))(DESCRIPTION(ADDRESS(PROTOCOLtcp)(HOST192.168.2.62)(PORT1521)))(DESCRIPTION(ADDRESS(PROTOCOLtcp)(HOST192.168.2.63)(PORT1521)))
Services Summary...
2.3 关闭两节点上的VIP及监听
GRID1关闭两节点vip及监听
srvctl stop listener -n racdb01
srvctl stop vip -n racdb0
srvctl stop listener -n racdb02
srvctl stop vip -n racdb02
或
srvctl stop vip -n racdb01 -f
srvctl stop vip -n racdb02 -f
停掉vip之后两个节点上的vip地址消失。
以二节点为例
[gridracdb02 ~]$ ifconfig -a
ens33: flags4163UP,BROADCAST,RUNNING,MULTICAST mtu 1500inet 192.168.2.62 netmask 255.255.255.0 broadcast 192.168.2.255inet6 fe80::7abc:4983:ac14:e0dd prefixlen 64 scopeid 0x20linkether 00:0c:29:12:08:eb txqueuelen 1000 (Ethernet)RX packets 1788 bytes 213310 (208.3 KiB)RX errors 0 dropped 0 overruns 0 frame 0TX packets 1265 bytes 204969 (200.1 KiB)TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0ens36: flags4163UP,BROADCAST,RUNNING,MULTICAST mtu 1500inet 10.10.10.38 netmask 255.255.255.0 broadcast 10.10.10.255
正常情况下 [oracleracdb01 dbs]$ ifconfig -a
ens33: flags4163UP,BROADCAST,RUNNING,MULTICAST mtu 1500inet 192.168.2.60 netmask 255.255.255.0 broadcast 192.168.2.255inet6 fe80::a22b:7bcb:ba5b:566c prefixlen 64 scopeid 0x20linkether 00:0c:29:a5:2b:c7 txqueuelen 1000 (Ethernet)RX packets 1197951 bytes 1357345599 (1.2 GiB)RX errors 0 dropped 0 overruns 0 frame 0TX packets 35190 bytes 7038721 (6.7 MiB)TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0ens33:1: flags4163UP,BROADCAST,RUNNING,MULTICAST mtu 1500inet 192.168.2.61 netmask 255.255.255.0 broadcast 192.168.2.255ether 00:0c:29:a5:2b:c7 txqueuelen 1000 (Ethernet)
2.4 根据VIP配置信息修改VIP
root
格式 srvctl modify nodeapps -n hostname1 -A hostname1-vip/255.255.255.0/网卡cd /u01/app/19.3.0/grid/
bin/srvctl modify nodeapps -n racdb01 -A 192.168.2.161/255.255.255.0/ens33
bin/srvctl modify nodeapps -n racdb02 -A 192.168.2.163/255.255.255.0/ens33
2.5 修改/etc/hosts
两个节点改成以下信息 ############Virtual IP############
192.168.2.161 racdb01-vip
192.168.2.163 racdb02-vip
2.6 验证VIP
srvctl config nodeapps -asrvctl config vip -n racdb01
srvctl config vip -n racdb02ip a
查看监听
lsnrctl status
三、变更SCAN-IP
3.1 关闭SCAN服务及监听
关闭scan监听
srvctl stop scan_listener
srvctl stop scan查看
srvctl status scan_listener
3.2 修改/etc/hosts
两个节点均要操作
############Scan IP###############
192.168.2.164 racdb-scan
3.3 修改SCAN IP
root格式srvctl modify scan -n scan-IP名srvctl modify scan -n racdb-scan
3.4 启动scan服务及监听
srvctl start scan_listener
srvctl start scan
3.5 检查
检查监听
[gridracdb02 ~]$ lsnrctl status listener_scan(DESCRIPTION(ADDRESS(PROTOCOLtcp)(HOST192.168.2.164)(PORT1521)))
Service ORCL has 1 instance(s).Instance YBDBINST1, status READY, has 1 handler(s) for this service...
Service yunnbeedXDB has 1 instance(s).Instance YBDBINST1, status READY, has 1 handler(s) for this service...
检查服务
[gridracdb02 ~]$ srvctl status scan_listener
SCAN Listener LISTENER_SCAN1 is enabled
SCAN listener LISTENER_SCAN1 is running on node racdb02
四、私网变更
变更类型
配置双私网变更当前私网IP
4.1 添加私网网卡 oifcfg getif oifcfg setif -global ens38/10.10.20.0:cluster_interconnectoifcfg getif
实验1关闭节点2上双私网中的一个观察集群日志
4.2. 变更私网
1、添加
oifcfg setif -global ens38/10.10.20.0:cluster_interconnect,asm2、查看
[gridracdb01 ~]$ oifcfg getif
ens36 10.10.10.0 global cluster_interconnect,asm
ens39 192.168.2.0 global public
ens38 10.10.20.0 global cluster_interconnect,asm3、加入一个新的 ASMLISTENE
srvctl add listener -asmlistener -l ASMNEWLSNR_ASM -subnet 10.10.20.04、查看当前的ASMLISNTER
[gridracdb02 ~]$ srvctl status asmnetwork
ASM network is running on racdb02,racdb01[gridracdb01 ~]$ srvctl config asmnetwork
ASM network 1 exists
Subnet IPv4: 10.10.10.0//
Subnet IPv6:
Network is enabled
Network is individually enabled on nodes:
Network is individually disabled on nodes: [gridracdb01 ~]$ srvctl config listener -asmlistener
Name: ASMNET1LSNR_ASM
Type: ASM Listener
Owner: grid
Subnet: 10.10.10.0
Home: CRS home
End points: TCP:1525
Listener is enabled.
Listener is individually enabled on nodes:
Listener is individually disabled on nodes:5、删除现有的ASMLISTENER
[gridracdb01 ~]$ srvctl update listener -listener ASMNET1LSNR_ASM -asm -remove -force lsnrctl stop ASMNET1LSNR_ASM 6、查看
[gridracdb01 ~]$ srvctl config listener -asmlistener
Name: ASMNEWLSNR_ASM
Type: ASM Listener
Owner: grid
Subnet: 10.10.20.0
Home: CRS home
End points: TCP:1526
Listener is enabled.
Listener is individually enabled on nodes:
Listener is individually disabled on nodes: 4.2 删除私网 oifcfg delif -global ens38/10.10.20.0
