标签：指定 硬盘 lte online gen copy end shmall 网卡
软件环境：VMware、redhat6.6、oracle12c（linuxx64_12201_database.zip）、12cgrid（linuxx64_12201_grid_home.zip）
一、前期准备工作
虚拟机先配置一个节点即可，第二个节点由第一个节点克隆再修改相关参数（环境变量中的sid名称、网络等）
1.1、服务器基本配置（操作系统、安装包、网络、用户、环境变量）
1.1.1、服务器安装操作系统
选择最小安装即可，磁盘分配：35G，内存：4G(最少可能也得2G)，swap：8G
关闭防火墙、SELinux
关闭ntpd（mv /etc/ntp.conf /etc/ntp.conf_bak）
添加四块网卡：分别用于公网（仅主机）、私网（vlan1）、存储链接2路（vlan2）
1.1.2、检查并安装oracle12c需要的rpm包
检查
rpm -q binutils compat-libcap1 compat-libstdc++-33 e2fsprogs e2fsprogs-libs glibc glibc-devel ksh libaio-devel libaio libgcc libstdc++ libstdc++-devel libxcb libX11 libXau libXi libXtst make net-tools nfs-utils smartmontools sysstat
将查询到的未安装的包安装（VMware连接镜像，配置本地yum）
[root@jydb1 ~]#mount /dev/cdrom /mnt
[root@jydb1 ~]# cat /etc/yum.repos.d/rhel-source.repo
[ISO] name=iso baseurl=file:///mnt enabled=1 gpgcheck=0
yum install安装
yum install binutils compat-libcap1 compat-libstdc++-33 e2fsprogs e2fsprogs-libs glibc glibc-devel ksh libaio-devel libaio libgcc libstdc++ libstdc++-devel libxcb libX11 libXau libXi libXtst make net-tools nfs-utils smartmontools sysstat
另外再安装cvuqdisk包（rac_grid自检需要的包）
rpm -qi cvuqdisk CVUQDISK_GRP=oinstall; export CVUQDISK_GRP \\这里需要先创建oinstall组再安装，后面教程有创建，所以等创建后再进行这一步 rpm -iv cvuqdisk-1.0.10-1.rpm
1.1.3、配置各节点的/etc/hosts
[root@jydb1 ~]# cat /etc/hosts 127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4 jydb1.rac ::1 localhost localhost.localdomain localhost6 localhost6.localdomain6 jydb1.rac #eth0 public 192.168.137.11 jydb1 192.168.137.12 jydb2 #eth0 vip 192.168.137.21 jydb1-vip 192.168.137.22 jydb2-vip #eth1 private 10.0.0.1 jydb1-priv 10.0.0.2 jydb2-priv 10.0.0.11 jydb1-priv2 10.0.0.22 jydb2-priv2 #scan ip 192.168.137.137 jydb-cluster-scan
1.1.4、各节点创建需要的用户和组
创建group & user：
groupadd -g 54321 oinstall groupadd -g 54322 dba groupadd -g 54323 oper groupadd -g 54324 backupdba groupadd -g 54325 dgdba groupadd -g 54326 kmdba groupadd -g 54327 asmdba groupadd -g 54328 asmoper groupadd -g 54329 asmadmin groupadd -g 54330 racdba useradd -u 54321 -g oinstall -G dba,asmdba,backupdba,dgdba,kmdba,racdba,oper oracle useradd -u 54322 -g oinstall -G asmadmin,asmdba,asmoper,dba grid
自行设置oracle、grid密码
1.1.5、各节点创建安装目录（root）
mkdir -p /u01/app/12.2.0/grid mkdir -p /u01/app/grid mkdir -p /u01/app/oracle chown -R grid:oinstall /u01 chown oracle:oinstall /u01/app/oracle chmod -R 775 /u01/
1.1.6、各节点配置文件修改
内核参数修改：vi /etc/sysctl.conf
# vi /etc/sysctl.conf 增加如下内容： fs.file-max = 6815744 kernel.sem = 250 32000 100 128 kernel.shmmni = 4096 kernel.shmall = 1073741824 kernel.shmmax = 6597069766656 kernel.panic_on_oops = 1 net.core.rmem_default = 262144 net.core.rmem_max = 4194304 net.core.wmem_default = 262144 net.core.wmem_max = 1048576 net.ipv4.conf.eth3.rp_filter = 2 net.ipv4.conf.eth2.rp_filter = 2 net.ipv4.conf.eth0.rp_filter = 1 fs.aio-max-nr = 1048576 net.ipv4.ip_local_port_range = 9000 65500
修改生效：sysctl -p
用户shell的限制：vi /etc/security/limits.conf
#在/etc/security/limits.conf 增加如下内容： grid soft nproc 2047 grid hard nproc 16384 grid soft nofile 1024 grid hard nofile 65536 grid soft stack 10240 oracle soft nproc 2047 oracle hard nproc 16384 oracle soft nofile 1024 oracle hard nofile 65536 oracle soft stack 10240
-加载 pam_limits.so插入式认证模块：vi /etc/pam.d/login
vi /etc/pam.d/login 添加如下内容：
session required pam_limits.so
1.1.7、各节点用户环境变量配置
[root@jydb1 ~]# cat /home/grid/.bash_profile
export ORACLE_SID=+ASM1; export ORACLE_HOME=/u01/app/12.2.0/grid; export PATH=$ORACLE_HOME/bin:$PATH; export LD_LIBRARY_PATH=$ORACLE_HOME/lib:/lib:/usr/lib; export CLASSPATH=$ORACLE_HOME/JRE:$ORACLE_HOME/jlib:$ORACLE_HOME/rdbms/jlib export DISPLAY=192.168.88.121:0.0
[root@jydb1 ~]# cat /home/oracle/.bash_profile
export ORACLE_SID=racdb1; export ORACLE_HOME=/u01/app/oracle/product/12.2.0/db_1; export ORACLE_HOSTNAME=jydb1; export PATH=$ORACLE_HOME/bin:$PATH; export LD_LIBRARY_PATH=$ORACLE_HOME/lib:/lib:/usr/lib; export CLASSPATH=$ORACLE_HOME/JRE:$ORACLE_HOME/jlib:$ORACLE_HOME/rdbms/jlib; export DISPLAY=192.168.88.121:0.0
上面的步骤完成后可以克隆node2了
1.1.8、配置各节点ssh互信
克隆出第二台，网络更改没问题后
以grid用户为例，oracle用户同样要配置互信：
①先生成节点一grid的公钥 [grid@jydb1 ~]$ ssh-keygen -t rsa -P ‘‘ Generating public/private rsa key pair. Enter file in which to save the key (/home/grid/.ssh/id_rsa): Your identification has been saved in /home/grid/.ssh/id_rsa. Your public key has been saved in /home/grid/.ssh/id_rsa.pub.

[grid@jydb2 .ssh]$ ssh jydb2-priv date
2018年 03月 30日 星期五 08:01:20 CST
jydb2上只需要修改蓝色字体
1.2、共享存储配置
添加一台服务器模拟存储服务器，配置两个私有地址和rac客户端连接多路径，磁盘划分和配置
目标：从存储中划分出来两台主机可以同时看到的共享LUN，一共六个：3个1G的盘用作OCR和Voting Disk，1个40G的盘做GIMR，其余规划做数据盘和FRA。
为存储服务器加63g的硬盘
//2.3的lv划分 asmdisk1 1G asmdisk2 1G asmdisk3 1G asmdisk4 40G asmdisk5 10G asmdisk6 10G
1.2.1、rac为存储客户端，添加连接存储的网卡（数量2）
VMware建立vlan2，两个rac节点、存储服务器上均添加两块网卡，划分到vlan2，这样就可以通过多路径和存储进行连接。
存储（服务端）：10.0.1.99、10.0.2.99
rac-jydb1（客户端）：10.0.1.150、10.0.2.150
rac-jydb2（客户端）：10.0.1.151、10.0.2.151
最后测试网路互通没问题即可进行下一步
1.2.2、安装iscsi软件包
--服务端
yum安装scsi-target-utils
yum install scsi-target-utils
--客户端
yum安装iscsi-initiator-utils
yum install iscsi-initiator-utils
1.2.3、模拟存储加盘
--服务端操作
填加一个63G的盘，实际就是用来模拟存储新增实际的一块盘。
我这里新增加的盘显示为/dev/sdb，我将它创建成lvm
# pvcreate /dev/sdb Physical volume "/dev/sdb" successfully created # vgcreate vg_storage /dev/sdb Volume group "vg_storage" successfully created # lvcreate -L 10g -n lv_lun1 vg_storage //按照之前划分的磁盘容量分配多少g Logical volume "lv_lun1" created
1.2.4、配置iscsi服务端
iSCSI服务端主要配置文件：/etc/tgt/targets.conf
所以我这里按照规范设置的名称，添加好如下配置：
<target iqn.2018-03.com.cnblogs.test:alfreddisk> backing-store /dev/vg_storage/lv_lun1 # Becomes LUN 1 backing-store /dev/vg_storage/lv_lun2 # Becomes LUN 2 backing-store /dev/vg_storage/lv_lun3 # Becomes LUN 3 backing-store /dev/vg_storage/lv_lun4 # Becomes LUN 4 backing-store /dev/vg_storage/lv_lun5 # Becomes LUN 5 backing-store /dev/vg_storage/lv_lun6 # Becomes LUN 6 </target>
配置完成后，就启动服务和设置开机自启动：
[root@Storage ~]# service tgtd start Starting SCSI target daemon: [ OK ] [root@Storage ~]# chkconfig tgtd on [root@Storage ~]# chkconfig --list|grep tgtd tgtd 0:off 1:off 2:on 3:on 4:on 5:on 6:off [root@Storage ~]# service tgtd status tgtd (pid 1763 1760) is running...
然后查询下相关的信息，比如占用的端口、LUN信息（Type：disk）：
[root@Storage ~]# netstat -tlunp |grep tgt tcp 0 0 0.0.0.0:3260 0.0.0.0:* LISTEN 1760/tgtd tcp 0 0 :::3260 :::* LISTEN 1760/tgtd [root@Storage ~]# tgt-admin --show Target 1: iqn.2018-03.com.cnblogs.test:alfreddisk System information: Driver: iscsi State: ready I_T nexus information: LUN information: LUN: 0 Type: controller SCSI ID: IET 00010000 SCSI SN: beaf10 Size: 0 MB, Block size: 1 Online: Yes Removable media: No Prevent removal: No Readonly: No Backing store type: null Backing store path: None Backing store flags: LUN: 1 Type: disk SCSI ID: IET 00010001 SCSI SN: beaf11 Size: 10737 MB, Block size: 512 Online: Yes Removable media: No Prevent removal: No Readonly: No Backing store type: rdwr Backing store path: /dev/vg_storage/lv_lun1 Backing store flags: Account information: ACL information: ALL
1.2.5、配置iscsi客户端
确认开机启动项设置开启：
# chkconfig --list|grep scsi iscsi 0:off 1:off 2:off 3:on 4:on 5:on 6:off iscsid 0:off 1:off 2:off 3:on 4:on 5:on 6:off
使用iscsiadm命令扫描服务端的LUN（探测iSCSI Target）
iscsiadm -m discovery -t sendtargets -p 10.0.1.99
[root@jydb1 ~]# iscsiadm -m discovery -t sendtargets -p 10.0.1.99 10.0.1.99:3260,1 iqn.2018-03.com.cnblogs.test:alfreddisk [root@jydb1 ~]# iscsiadm -m discovery -t sendtargets -p 10.0.2.99 10.0.2.99:3260,1 iqn.2018-03.com.cnblogs.test:alfreddisk
查看iscsiadm -m node
[root@jydb1 ~]# iscsiadm -m node
10.0.1.99:3260,1 iqn.2018-03.com.cnblogs.test:alfreddisk
10.0.2.99:3260,1 iqn.2018-03.com.cnblogs.test:alfreddisk
查看/var/lib/iscsi/nodes/下的文件：
[root@jydb1 ~]# ll -R /var/lib/iscsi/nodes/ /var/lib/iscsi/jydbs/: 总用量 4 drw------- 4 root root 4096 3月 29 00:59 iqn.2018-03.com.cnblogs.test:alfreddisk /var/lib/iscsi/jydbs/iqn.2018-03.com.cnblogs.test:alfreddisk: 总用量 8 drw------- 2 root root 4096 3月 29 00:59 10.0.1.99,3260,1 drw------- 2 root root 4096 3月 29 00:59 10.0.2.99,3260,1 /var/lib/iscsi/jydbs/iqn.2018-03.com.cnblogs.test:alfreddisk/10.0.1.99,3260,1: 总用量 4 -rw------- 1 root root 2049 3月 29 00:59 default /var/lib/iscsi/jydbs/iqn.2018-03.com.cnblogs.test:alfreddisk/10.0.2.99,3260,1: 总用量 4 -rw------- 1 root root 2049 3月 29 00:59 default
挂载iscsi磁盘
根据上面探测的结果，执行下面命令，挂载共享磁盘：
iscsiadm -m node -T iqn.2018-03.com.cnblogs.test:alfreddisk --login
[root@jydb1 ~]# iscsiadm -m node -T iqn.2018-03.com.cnblogs.test:alfreddisk --login Logging in to [iface: default, target: iqn.2018-03.com.cnblogs.test:alfreddisk, portal: 10.0.2.99,3260] (multiple) Logging in to [iface: default, target: iqn.2018-03.com.cnblogs.test:alfreddisk, portal: 10.0.1.99,3260] (multiple) Login to [iface: default, target: iqn.2018-03.com.cnblogs.test:alfreddisk, portal: 10.0.2.99,3260] successful. Login to [iface: default, target: iqn.2018-03.com.cnblogs.test:alfreddisk, portal: 10.0.1.99,3260] successful.
显示挂载成功
通过（fdisk -l或lsblk）命令查看挂载的iscsi硬盘
[root@jydb1 ~]# lsblk NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINT sda 8:0 0 35G 0 disk ├─sda1 8:1 0 200M 0 part /boot ├─sda2 8:2 0 7.8G 0 part [SWAP] └─sda3 8:3 0 27G 0 part / sr0 11:0 1 3.5G 0 rom /mnt sdb 8:16 0 1G 0 disk sdc 8:32 0 1G 0 disk sdd 8:48 0 1G 0 disk sde 8:64 0 1G 0 disk sdf 8:80 0 1G 0 disk sdg 8:96 0 1G 0 disk sdi 8:128 0 40G 0 disk sdk 8:160 0 10G 0 disk sdm 8:192 0 10G 0 disk sdj 8:144 0 10G 0 disk sdh 8:112 0 40G 0 disk sdl 8:176 0 10G 0 disk
1.2.6、配置multipath多路径
安装多路径软件包：
rpm -qa |grep device-mapper-multipath
没有安装则yum安装
#yum install -y device-mapper-multipath
或下载安装这两个rpm
device-mapper-multipath-libs-0.4.9-72.el6.x86_64.rpm
device-mapper-multipath-0.4.9-72.el6.x86_64.rpm
添加开机启动
chkconfig multipathd on
生成多路径配置文件
--生成multipath配置文件 /sbin/mpathconf --enable --显示多路径的布局 multipath -ll --重新刷取 multipath -v2 或-v3 --清空所有多路径 multipath -F
以下是操作输出，供参考
[root@jydb1 ~]# multipath -v3
[root@jydb1 ~]# multipath -ll Mar 29 03:40:10 | multipath.conf line 109, invalid keyword: multipaths Mar 29 03:40:10 | multipath.conf line 115, invalid keyword: multipaths Mar 29 03:40:10 | multipath.conf line 121, invalid keyword: multipaths Mar 29 03:40:10 | multipath.conf line 127, invalid keyword: multipaths Mar 29 03:40:10 | multipath.conf line 133, invalid keyword: multipaths Mar 29 03:40:10 | multipath.conf line 139, invalid keyword: multipaths asmdisk6 (1IET 00010006) dm-5 IET,VIRTUAL-DISK //wwid size=10.0G features=‘0‘ hwhandler=‘0‘ wp=rw |-+- policy=‘round-robin 0‘ prio=1 status=active | `- 33:0:0:6 sdj 8:144 active ready running `-+- policy=‘round-robin 0‘ prio=1 status=enabled `- 34:0:0:6 sdm 8:192 active ready running asmdisk5 (1IET 00010005) dm-2 IET,VIRTUAL-DISK size=10G features=‘0‘ hwhandler=‘0‘ wp=rw |-+- policy=‘round-robin 0‘ prio=1 status=active | `- 33:0:0:5 sdh 8:112 active ready running `-+- policy=‘round-robin 0‘ prio=1 status=enabled `- 34:0:0:5 sdl 8:176 active ready running asmdisk4 (1IET 00010004) dm-4 IET,VIRTUAL-DISK size=40G features=‘0‘ hwhandler=‘0‘ wp=rw |-+- policy=‘round-robin 0‘ prio=1 status=active | `- 33:0:0:4 sdf 8:80 active ready running `-+- policy=‘round-robin 0‘ prio=1 status=enabled `- 34:0:0:4 sdk 8:160 active ready running asmdisk3 (1IET 00010003) dm-3 IET,VIRTUAL-DISK size=1.0G features=‘0‘ hwhandler=‘0‘ wp=rw |-+- policy=‘round-robin 0‘ prio=1 status=active | `- 33:0:0:3 sdd 8:48 active ready running `-+- policy=‘round-robin 0‘ prio=1 status=enabled `- 34:0:0:3 sdi 8:128 active ready running asmdisk2 (1IET 00010002) dm-1 IET,VIRTUAL-DISK size=1.0G features=‘0‘ hwhandler=‘0‘ wp=rw |-+- policy=‘round-robin 0‘ prio=1 status=active | `- 33:0:0:2 sdc 8:32 active ready running `-+- policy=‘round-robin 0‘ prio=1 status=enabled `- 34:0:0:2 sdg 8:96 active ready running asmdisk1 (1IET 00010001) dm-0 IET,VIRTUAL-DISK size=1.0G features=‘0‘ hwhandler=‘0‘ wp=rw |-+- policy=‘round-robin 0‘ prio=1 status=active | `- 33:0:0:1 sdb 8:16 active ready running `-+- policy=‘round-robin 0‘ prio=1 status=enabled `- 34:0:0:1 sde 8:64 active ready running
启动multipath服务
#service multipathd start
配置multipath
修改第一处： #建议user_friendly_names设为no。如果设定为 no，即指定该系统应使用WWID 作为该多路径的别名。如果将其设为 yes，系统使用文件 #/etc/multipath/mpathn 作为别名。 #当将 user_friendly_names 配置选项设为 yes 时，该多路径设备的名称对于一个节点来说是唯一的，但不保证对使用多路径设备的所有节点都一致。也就是说， 在节点一上的mpath1和节点二上的mpath1可能不是同一个LUN，但是各个服务器上看到的相同LUN的WWID都是一样的，所以不建议设为yes，而是设为#no，用WWID作为别名。 defaults { user_friendly_names no path_grouping_policy failover //表示multipath工作模式为主备，path_grouping_policy multibus为主主 } 添加第二处：绑定wwid<br>这里的wwid在multipath -l中体现 multipaths { multipath { wwid "1IET 00010001" alias asmdisk1 } multipaths { multipath { wwid "1IET 00010002" alias asmdisk2 } multipaths { multipath { wwid "1IET 00010003" alias asmdisk3 } multipaths { multipath { wwid "1IET 00010003" alias asmdisk3 } multipaths { multipath { wwid "1IET 00010004" alias asmdisk4 } multipaths { multipath { wwid "1IET 00010005" alias asmdisk5 } multipaths { multipath { wwid "1IET 00010006" alias asmdisk6 }
配置完成要生效得重启multipathd
绑定后查看multipath别名
[root@jydb1 ~]# cd /dev/mapper/
[root@jydb1 mapper]# ls
asmdisk1 asmdisk2 asmdisk3 asmdisk4 asmdisk5 asmdisk6 control
udev绑定裸设备
首先进行UDEV权限绑定，否则权限不对安装时将扫描不到共享磁盘
修改之前：
[root@jydb1 ~]# ls -lh /dev/dm* brw-rw---- 1 root disk 253, 0 4月 2 16:18 /dev/dm-0 brw-rw---- 1 root disk 253, 1 4月 2 16:18 /dev/dm-1 brw-rw---- 1 root disk 253, 2 4月 2 16:18 /dev/dm-2 brw-rw---- 1 root disk 253, 3 4月 2 16:18 /dev/dm-3 brw-rw---- 1 root disk 253, 4 4月 2 16:18 /dev/dm-4 brw-rw---- 1 root disk 253, 5 4月 2 16:18 /dev/dm-5 crw-rw---- 1 root audio 14, 9 4月 2 16:18 /dev/dmmidi
我这里系统是RHEL6.6，对于multipath的权限，手工去修改几秒后会变回root。所以需要使用udev去绑定好权限。
搜索对应的配置文件模板：
[root@jyrac1 ~]# find / -name 12-* /usr/share/doc/device-mapper-1.02.79/12-dm-permissions.rules
根据模板新增12-dm-permissions.rules文件在/etc/udev/rules.d/下面：
vi /etc/udev/rules.d/12-dm-permissions.rules # MULTIPATH DEVICES # # Set permissions for all multipath devices ENV{DM_UUID}=="mpath-?*", OWNER:="grid", GROUP:="asmadmin", MODE:="660" //修改这里 # Set permissions for first two partitions created on a multipath device (and detected by kpartx) # ENV{DM_UUID}=="part[1-2]-mpath-?*", OWNER:="root", GROUP:="root", MODE:="660"
完成后启动start_udev，30s后权限正常则OK
[root@jydb1 ~]# start_udev 正在启动 udev：[确定] [root@jydb1 ~]# ls -lh /dev/dm* brw-rw---- 1 grid asmadmin 253, 0 4月 2 16:25 /dev/dm-0 brw-rw---- 1 grid asmadmin 253, 1 4月 2 16:25 /dev/dm-1 brw-rw---- 1 grid asmadmin 253, 2 4月 2 16:25 /dev/dm-2 brw-rw---- 1 grid asmadmin 253, 3 4月 2 16:25 /dev/dm-3 brw-rw---- 1 grid asmadmin 253, 4 4月 2 16:25 /dev/dm-4 brw-rw---- 1 grid asmadmin 253, 5 4月 2 16:25 /dev/dm-5 crw-rw---- 1 root audio 14, 9 4月 2 16:24 /dev/dmmidi
