Linux平台 Oracle 19c RAC安装指导：
Part1：
Part2：
Part3：
本文安装环境： OEL 7.6 + Oracle 19.3 GI & RAC
一、实施前期准备工作
1.1 服务器安装操作系统
配置完全相同的两台服务器，安装相同版本的Linux操作系统。留存系统光盘或者镜像文件。
我这里是OEL7.6，系统目录大小均一致。对应OEL7.6的系统镜像文件放在服务器上，供后面配置本地yum使用。
1.2 Oracle安装介质
Oracle 19.3 版本2个zip包(总大小6G+,注意空间)：
LINUX.X64_193000_grid_home.zip MD5:
LINUX.X64_193000_db_home.zip MD5:
这个自己去Oracle官网下载，然后只需要上传到节点1即可。
1.3 共享存储规划
从存储中划分出两台主机可以同时看到的共享LUN，3个1G的盘用作OCR和Voting Disk，其余分了3个12G的盘规划做用做数据盘和FRA。
注：19c安装GI时，可以选择是否配置GIMR，且默认不配置，我这里选择不配置，所以无需再给GIMR分配对应空间。
--OEL7使用udev需要给磁盘创建分区，这里我使用fdisk 将对应盘创建一个主分区，分区号为2（这里只是为了区分）:sdb sdc sdd sde sdf sdg sdb2 sdc2 sdd2 sde2 sdf2 sdg21G 1G 1G 12G 12G 12G--OEL7中udev需绑定对应磁盘的分区for i in b c d e f g;doecho "KERNEL==\"sd?2\", SUBSYSTEM==\"block\", PROGRAM==\"/usr/lib/udev/scsi_id -g -u -d /dev/\$parent\", RESULT==\"`/usr/lib/udev/scsi_id -g -u -d /dev/sd\$i`\", SYMLINK+=\"asm-disk$i\", OWNER=\"grid\", GROUP=\"asmadmin\", MODE=\"0660\"" done--vi /etc/udev/rules.d/99-oracle-asmdevices.rulesKERNEL=="sd?2", SUBSYSTEM=="block", PROGRAM=="/usr/lib/udev/scsi_id -g -u -d /dev/$parent", RESULT=="1ATA_VBOX_HARDDISK_VB208b8d32-df9af9d6", SYMLINK+="asm-ocr1", OWNER="grid", GROUP="asmadmin", MODE="0660"KERNEL=="sd?2", SUBSYSTEM=="block", PROGRAM=="/usr/lib/udev/scsi_id -g -u -d /dev/$parent", RESULT=="1ATA_VBOX_HARDDISK_VBe51f4d0a-1b73c589", SYMLINK+="asm-ocr2", OWNER="grid", GROUP="asmadmin", MODE="0660"KERNEL=="sd?2", SUBSYSTEM=="block", PROGRAM=="/usr/lib/udev/scsi_id -g -u -d /dev/$parent", RESULT=="1ATA_VBOX_HARDDISK_VBc63b1aa3-1e290288", SYMLINK+="asm-ocr3", OWNER="grid", GROUP="asmadmin", MODE="0660"KERNEL=="sd?2", SUBSYSTEM=="block", PROGRAM=="/usr/lib/udev/scsi_id -g -u -d /dev/$parent", RESULT=="1ATA_VBOX_HARDDISK_VB53ee20b6-40c4b9a3", SYMLINK+="asm-data01", OWNER="grid", GROUP="asmadmin", MODE="0660"KERNEL=="sd?2", SUBSYSTEM=="block", PROGRAM=="/usr/lib/udev/scsi_id -g -u -d /dev/$parent", RESULT=="1ATA_VBOX_HARDDISK_VB3822afbf-62d8a84d", SYMLINK+="asm-data02", OWNER="grid", GROUP="asmadmin", MODE="0660"KERNEL=="sd?2", SUBSYSTEM=="block", PROGRAM=="/usr/lib/udev/scsi_id -g -u -d /dev/$parent", RESULT=="1ATA_VBOX_HARDDISK_VBfbb7943a-5ec216e5", SYMLINK+="asm-data03", OWNER="grid", GROUP="asmadmin", MODE="0660"--udevadm配置重载生效：[root@db193 rules.d]# udevadm control --reload[root@db193 rules.d]# udevadm trigger--确认udev已绑定成功:[root@db193 rules.d]# ls -l /dev/asm*lrwxrwxrwx. 1 root root 4 Jul 30 23:45 /dev/asm-data01 -> sde2lrwxrwxrwx. 1 root root 4 Jul 30 23:45 /dev/asm-data02 -> sdf2lrwxrwxrwx. 1 root root 4 Jul 30 23:45 /dev/asm-data03 -> sdg2lrwxrwxrwx. 1 root root 4 Jul 30 23:45 /dev/asm-ocr1 -> sdb2lrwxrwxrwx. 1 root root 4 Jul 30 23:45 /dev/asm-ocr2 -> sdc2lrwxrwxrwx. 1 root root 4 Jul 30 23:45 /dev/asm-ocr3 -> sdd2--第二个节点db195最开始直接使用udevadm操作发现不行，此时需先partprobe，再udevadm触发即可成功--使用partprobe将磁盘分区表变化信息通知内核，请求操作系统重新加载分区表[root@db195 ~]# partprobe /dev/sdb[root@db195 ~]# partprobe /dev/sdc[root@db195 ~]# partprobe /dev/sdd[root@db195 ~]# partprobe /dev/sde[root@db195 ~]# partprobe /dev/sdf[root@db195 ~]# partprobe /dev/sdg--udevadm配置重载生效：[root@db195 ~]# udevadm control --reload[root@db195 ~]# udevadm trigger--确认udev已绑定成功:[root@db195 ~]# ls -l /dev/asm*lrwxrwxrwx. 1 root root 4 Jul 30 23:49 /dev/asm-data01 -> sde2lrwxrwxrwx. 1 root root 4 Jul 30 23:49 /dev/asm-data02 -> sdf2lrwxrwxrwx. 1 root root 4 Jul 30 23:49 /dev/asm-data03 -> sdg2lrwxrwxrwx. 1 root root 4 Jul 30 23:49 /dev/asm-ocr1 -> sdb2lrwxrwxrwx. 1 root root 4 Jul 30 23:49 /dev/asm-ocr2 -> sdc2lrwxrwxrwx. 1 root root 4 Jul 30 23:49 /dev/asm-ocr3 -> sdd2
我这次搭建的实验环境为了精简，没有再去模拟多路径的环境，如果想尽可能的模拟生产环境，可以参考之前18c的配置：
1.4 网络规范分配
公有网络 以及 私有网络。
公有网络：这里实验环境是enp0s3是public IP，enp0s8是ASM & Private IP，实际生产需根据实际情况调整规划，一般public是有OS层绑定（bonding），private是使用HAIP。
二、安装前期准备工作
2.1 各节点系统时间校对
各节点系统时间校对:
--检验时间和时区确认正确date --关闭chrony服务，移除chrony配置文件（后续使用ctss）systemctl list-unit-files|grep chronydsystemctl status chronydsystemctl disable chronydsystemctl stop chronydmv /etc/chrony.conf /etc/chrony.conf_bak
这里实验环境，选择不使用NTP和chrony，这样Oracle会自动使用自己的ctss服务。
2.2 各节点关闭防火墙和SELinux
各节点关闭防火墙:
systemctl list-unit-files|grep firewalldsystemctl status firewalldsystemctl disable firewalldsystemctl stop firewalld
各节点关闭SELinux:
getenforcecat /etc/selinux/config手工修改/etc/selinux/config SELINUX=disabled，或使用下面命令：sed -i '/^SELINUX=.*/ s//SELINUX=disabled/' /etc/selinux/configsetenforce 0
最后核实各节点已经关闭SELinux即可。
2.3 各节点检查系统依赖包安装情况
yum install -y oracle-database-preinstall-18c-1.0-1.el7.x86_64
在OEL7.6中还是oracle-database-preinstall-18c的名字，并没有对应19c的，但实际测试，在依赖包方面基本没区别。
如果选用的是其他Linux，比如常用的RHEL，那就需要yum安装官方文档要求的依赖包了。
2.4 各节点配置/etc/hosts
编辑/etc/hosts文件：
#public ip192.168.1.193 db193192.168.1.195 db195#virtual ip192.168.1.194 db193-vip192.168.1.196 db195-vip#scan ip192.168.1.197 db19c-scan#private ip10.10.1.193 db193-priv10.10.1.195 db195-priv
修改主机名(建议由SA调整)：
--例如：修改主机名为db193:hostnamectl statushostnamectl set-hostname db193hostnamectl status
2.5 各节点创建需要的用户和组
创建group & user，给oracle、grid设置密码：
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 echo oracle | passwd --stdin oracleecho oracle | passwd --stdin grid
我这里测试环境设置密码都是oracle，实际生产环境建议设置符合规范的复杂密码。
2.6 各节点创建安装目录
各节点创建安装目录(root用户)：
mkdir -p /u01/app/19.3.0/gridmkdir -p /u01/app/gridmkdir -p /u01/app/oraclechown -R grid:oinstall /u01chown oracle:oinstall /u01/app/oraclechmod -R 775 /u01/
2.7 各节点系统配置文件修改
内核参数修改：vi /etc/sysctl.conf
实际上OEL在安装依赖包的时候也同时修改了这些值，以下参数主要是核对或是对RHEL版本作为参考：
# vi /etc/sysctl.conf 增加如下内容：vm.swappiness = 1vm.dirty_background_ratio = 3vm.dirty_ratio = 80vm.dirty_expire_centisecs = 500vm.dirty_writeback_centisecs = 100kernel.shmmni = 4096 kernel.shmall = 1073741824 kernel.shmmax = 4398046511104kernel.sem = 250 32000 100 128net.ipv4.ip_local_port_range = 9000 65500 net.core.rmem_default = 262144net.core.rmem_max = 4194304net.core.wmem_default = 262144net.core.wmem_max = 1048576 fs.aio-max-nr = 1048576fs.file-max = 6815744kernel.panic_on_oops = 1net.ipv4.conf.enp0s8.rp_filter = 2net.ipv4.conf.enp0s9.rp_filter = 2net.ipv4.conf.enp0s10.rp_filter = 2
修改生效：
#sysctl -p /etc/sysctl.conf
注：enp0s9和enp0s10是IPSAN专用的网卡，跟私网一样设置loose mode。（我这里因为没有使用IPSAN，所以没有这两张网卡）
#sysctl -p /etc/sysctl.d/98-oracle.confnet.ipv4.conf.enp0s8.rp_filter = 2net.ipv4.conf.enp0s9.rp_filter = 2net.ipv4.conf.enp0s10.rp_filter = 2
用户shell的限制：vi /etc/security/limits.d/99-grid-oracle-limits.conf
oracle soft nproc 16384oracle hard nproc 16384oracle soft nofile 1024oracle hard nofile 65536oracle soft stack 10240oracle hard stack 32768grid soft nproc 16384grid hard nproc 16384grid soft nofile 1024grid hard nofile 65536grid soft stack 10240grid hard stack 32768
这里需要注意OEL自动配置的 /etc/security/limits.d/oracle-database-server-12cR2-preinstall.conf 并不包含grid用户的，可以手工加上。
vi /etc/profile.d/oracle-grid.sh
#Setting the appropriate ulimits for oracle and grid userif [ $USER = "oracle" ]; then if [ $SHELL = "/bin/ksh" ]; then ulimit -u 16384 ulimit -n 65536 else ulimit -u 16384 -n 65536 fifiif [ $USER = "grid" ]; then if [ $SHELL = "/bin/ksh" ]; then ulimit -u 16384 ulimit -n 65536 else ulimit -u 16384 -n 65536 fifi
这个OEL中也没有自动配置，需要手工配置。
2.8 各节点设置用户的环境变量
第1个节点grid用户：
export ORACLE_SID=+ASM1;export ORACLE_BASE=/u01/app/grid;export ORACLE_HOME=/u01/app/19.3.0/grid;export PATH=$ORACLE_HOME/bin:$PATH;export LD_LIBRARY_PATH=$ORACLE_HOME/lib:/lib:/usr/lib;
第2个节点grid用户：
export ORACLE_SID=+ASM2;export ORACLE_BASE=/u01/app/grid;export ORACLE_HOME=/u01/app/19.3.0/grid;export PATH=$ORACLE_HOME/bin:$PATH;export LD_LIBRARY_PATH=$ORACLE_HOME/lib:/lib:/usr/lib;
第1个节点oracle用户：
export ORACLE_SID=jydb1;export ORACLE_BASE=/u01/app/oracle;export ORACLE_HOME=/u01/app/oracle/product/19.3.0/db_1;export PATH=$ORACLE_HOME/bin:$PATH;export LD_LIBRARY_PATH=$ORACLE_HOME/lib:/lib:/usr/lib;
第2个节点oracle用户：
export ORACLE_SID=jydb2;export ORACLE_BASE=/u01/app/oracle;export ORACLE_HOME=/u01/app/oracle/product/19.3.0/db_1;export PATH=$ORACLE_HOME/bin:$PATH;export LD_LIBRARY_PATH=$ORACLE_HOME/lib:/lib:/usr/lib;
三、
Linux平台 Oracle 19c RAC安装指导：
Part1：
Part2：
Part3：
本文安装环境： OEL 7.6 + Oracle 19.3 GI & RAC
三、GI(Grid Infrastructure)安装
3.1 解压GI的安装包
su - grid
解压 GRID 到 GRID用户的$ORACLE_HOME下
[grid@db193 grid]$ pwd/u01/app/19.3.0/grid[grid@db193 grid]$ unzip /u01/media/LINUX.X64_193000_grid_home.zip
3.2 安装配置Xmanager软件
在自己的Windows系统上成功安装Xmanager Enterprise之后，运行Xstart.exe可执行程序，
配置如下
Session：db193
Host：192.168.1.193
Protocol：SSH
User Name：grid
Execution Command：/usr/bin/xterm -ls -display $DISPLAY
点击RUN，输入grid用户的密码可以正常弹出命令窗口界面，即配置成功。
当然也可以通过开启Xmanager - Passive，直接在SecureCRT连接的会话窗口中临时配置DISPLAY变量直接调用图形：
export DISPLAY=192.168.1.31:0.0
3.3 共享存储LUN的赋权
在《 》中已完成绑定和权限，这里不需要再次操作。
--只需确认两个节点链接文件(/dev/asm*)对应的sd[b-g]2的权限正确即可：# ls -l /dev/sd?2brw-rw---- 1 root disk 8, 2 Jul 31 09:13 /dev/sda2brw-rw---- 1 grid asmadmin 8, 18 Jul 31 18:06 /dev/sdb2brw-rw---- 1 grid asmadmin 8, 34 Jul 31 18:06 /dev/sdc2brw-rw---- 1 grid asmadmin 8, 50 Jul 31 18:06 /dev/sdd2brw-rw---- 1 grid asmadmin 8, 66 Jul 31 17:10 /dev/sde2brw-rw---- 1 grid asmadmin 8, 82 Jul 31 17:10 /dev/sdf2brw-rw---- 1 grid asmadmin 8, 98 Jul 31 17:10 /dev/sdg2
3.4 使用Xmanager图形化界面配置GI
Xmanager通过grid用户登录，进入$ORACLE_HOME目录，运行gridSetup配置GI
$ cd $ORACLE_HOME$ ./gridSetup.sh
其实从12cR2开始，GI的配置就跟之前有一些变化，19c也一样，下面来看下GI配置的整个图形化安装的过程截图：
注：这里Public网卡这里用的enp0s3，ASM&Private这里用的enp0s8。
注：这里有一个新的存储GIMR的，之前12c、18c版本都是选择是外部冗余的一个40G大小的盘（当初给很多刚接触安装12cRAC的DBA造成了不适），而在19c安装中可以看到默认就是不选择的，恢复了11g时代的清爽感，这点我个人觉得很赞。
注：这里跟之前区别不大，我依然是选择3块1G的盘，Normal冗余作为OCR和voting disk。
注：这里检查出来的问题都需要认真核对，确认确实可以忽略才可以点击“Ignore All”，如果这里检测出缺少某些RPM包，需要使用yum安装好。我这里是自己的测试环境，分的配置较低，所以有内存和swap检测不通过，实际生产环境不应出现。
注：执行root脚本，确保先在一节点执行完毕后，再在其他节点执行。
第一个节点root执行脚本：

这段时间从打印的日志来看，虽然耗时也比以前11g时代长，但实际相比12c的上一个版本18c来说却缩短了不少。
root脚本成功执行完后继续安装:
注：最后这个报错提示，查看日志发现是因为使用了一个scan ip的提示，可以忽略。
至此GI配置完成。

至此，19c的GI配置已全部完成。
Linux平台 Oracle 19c RAC安装Part3：DB配置
四、
Linux平台 Oracle 19c RAC安装指导：
Part1：
Part2：
Part3：
本文安装环境： OEL 7.6 + Oracle 19.3 GI & RAC
四、DB(Database)安装
4.1 解压DB的安装包
oracle用户登录，在$ORACLE_HOME下解压db包（19c的db也是像18c一样直接解压到$ORACLE_HOME下，免安装）：
[oracle@db193 ~]$ mkdir -p /u01/app/oracle/product/19.3.0/db_1[oracle@db193 ~]$ cd $ORACLE_HOME[oracle@db193 db_1]$ pwd/u01/app/oracle/product/19.3.0/db_1[oracle@db193 db_1]$ ls[oracle@db193 db_1]$ unzip /u01/media/LINUX.X64_193000_db_home.zip
4.2 DB软件配置
打开Xmanager软件，Oracle用户登录，配置数据库软件。
[oracle@db193 db_1]$ pwd/u01/app/oracle/product/19.3.0/db_1[oracle@db193 db_1]$ export DISPLAY=192.168.1.31:0.0[oracle@db193 db_1]$ ./runInstaller
下面截取DB软件配置的过程如下：
注：这里选择只安装软件，数据库后面创建好ASM磁盘组后再运行dbca创建。
注：配置好ssh等价性。
注：可以进行修复的，按提示执行脚本修复。
我这里还有swap的问题，因为是测试环境资源有限，可以忽略，如果生产环境，强烈建议调整符合要求。
如果还有其他的检查项未通过，则无论是生产还是测试环境，都不建议忽略，而应该整改符合要求为止。
注：最后root用户按安装提示执行1个脚本，需要在各节点分别执行。
至此，已完成DB软件的配置。
4.3 ASMCA创建磁盘组
打开Xmanager软件，grid用户登录，asmca创建ASM磁盘组
[grid@db193 ~]$ export DISPLAY=192.168.1.31:0.0[grid@db193 ~]$ asmca
使用asmca调用创建磁盘组的图形界面,首先映入眼帘的是鲜艳的19c配色图：
然后正式进入asmca的界面：
这里我先创建一个DATA磁盘组，一个FRA磁盘组，冗余选择external(生产如果选择external，底层存储必须已经做了RAID)。
这里看到新创建的DATA和FRA磁盘组已经创建完成并成功mount。
4.4 DBCA建库
打开Xmanager软件，oracle用户登录，dbca图形创建数据库。
下面是DBCA建库的过程截图：
注：这里选择是否启用CDB，并定义CDB和PDB的名称。我选择启用CDB，CDB名称为jydb，并自动创建2个PDB，前缀名就叫pdb。
注：这里我选择使用OMF，默认也是使用OMF。
注：这里我暂时没有启用FRA，后续调整开归档时将归档文件放在+FRA磁盘组中。
注：这里选择内存分配具体值，选择数据库的字符集，我这里没选择，字符集默认是AL32UTF8。需要根据实际情况修改。
注：这里可以选择是否配置EM，我这里选择配置，如果你不需要，可以选择不配置。CVU一般也不配置，我这里学习目的选择配置。
注：这里设置密码，我实验环境直接oracle，不符合规范，生产环境建议设置复杂密码。
注：这里可以选择将创建数据库的脚本保存下来，根据你的需求，可选可不选。
注：这里如果还有其他的检查未通过，则不能忽略。我这里是因为使用一个scan，对应报错可以忽略。
注：这里是安装信息的概览，建议认真核实，如果有不对的还可以退回去改。确认无误后开始创建数据库。
注：19c建库的时间还是和18c一样，长到让人崩溃，感觉以后DBA安装过程中可以提前下几个电影来边等边看了。
INFO: Aug 01, 2019 4:42:58 AM oracle.assistants.common.base.driver.AssistantConfigDriver updateExitStatus
INFO: Total time taken for DBCA operation in mm:ss is 286:16
至此，Oracle 19.3 RAC数据库已经创建成功，目前如果你的企业想上12c系列的数据库，推荐直接选择19c（12c的最终版本12.2.0.3），19c相对18c来说更趋于稳定，Oracle的支持周期也更长。
4.5 验证crsctl的状态
grid用户登录，crsctl stat res -t 查看集群资源的状态，发现各节点的DB资源已经正常Open。
