１.三台虚拟机 虚拟机的配置如下
2./etc/hosts 设定,一般情况下用Vｍware 两张网卡就可以了，不过可以用三张网卡
[root@nymtx asm]# cat /etc/hosts 127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4 ::1 localhost localhost.localdomain localhost6 localhost6.localdomain6 192.168.1.80 nymtx.inno.com nymtx 192.168.1.88 hzmtx.inno.com hzmtx 10.10.10.80 nymtx-prv.inno.com nymtx-prv 10.10.10.88 hzmtx-prv.inno.com hzmtx-prv 192.168.1.83 nymtx-vip.inno.com nymtx-vip 192.168.1.84 hzmtx-vip.inno.com hzmtx-vip 192.168.1.85 mtx-scan.inno.com mtx-scan 192.168.1.90 cnmtx.inno.com cnmtx
2.关防火墙,三台主机都做
echo "SELINUX=disabled" > /etc/selinux/config echo "#SELINUXTYPE=targeted " >> /etc/selinux/config setenforce 1 systemctl stop firewalld.service systemctl disable firewalld.service
3.禁止NTP 三台主机都做
systemctl stop ntpd systemctl disabled ntpd systemctl stop chronyd.service systemctl disable chronyd.service rm -f /etc/chrony.conf
4.安装组件(YUM配置请参考https://www.cnblogs.com/tingxin/p/13137951.html)
yum -y install xdpyinfo yum -y install libnsl yum -y install autoconf yum -y install automake yum -y install binutils yum -y install binutils-devel yum -y install bison yum -y install cpp yum -y install dos2unix yum -y install ftp yum -y install gcc yum -y install gcc-c++ yum -y install lrzsz yum -y install python-devel yum -y install compat-db* yum -y install compat-gcc-34 yum -y install compat-gcc-34-c++ yum -y install compat-libcap1 yum -y install compat-libstdc++-33 yum -y install compat-libstdc++-33.i686 yum -y install glibc-* yum -y install glibc-.i686 yum -y install libXpm-.i686 yum -y install libXp.so.6 yum -y install libXt.so.6 yum -y install libXtst.so.6 yum -y install libXext yum -y install libXext.i686 yum -y install libXtst yum -y install libXtst.i686 yum -y install libX11 yum -y install libX11.i686 yum -y install libXau yum -y install libXau.i686 yum -y install libxcb yum -y install libxcb.i686 yum -y install libXi yum -y install libXi.i686 yum -y install libXtst yum -y install libstdc++-docs yum -y install libgcc_s.so.1 yum -y install libstdc++.i686 yum -y install libstdc++-devel yum -y install libstdc++-devel.i686 yum -y install libaio yum -y install libaio.i686 yum -y install libaio-devel yum -y install libaio-devel.i686 yum -y install ksh yum -y install libXp yum -y install libaio-devel yum -y install numactl yum -y install numactl-devel yum -y install make -y yum -y install sysstat -y yum -y install unixODBC yum -y install unixODBC-devel yum -y install elfutils-libelf-devel yum -y install redhat-lsb-core yum -y install bc binutils elfutils-libelf elfutils-libelf-devel fontconfig-devel glibc glibc-devel ksh libaio libaio-devel libXrender libX11 libXau libXi libXtst libgcc libnsl librdmacm libstdc++ libstdc++-devel libxcb libibverbs make smartmontools sysstat
5. 创建用户,在RAC主机上(nymtx,hzmtx)
groupdel oinstall groupdel dba groupadd -g 5001 oinstall groupadd -g 5002 dba groupadd -g 5003 asmdba groupadd -g 5004 asmoper groupadd -g 5005 asmadmin useradd -u 6001 -g oinstall -G asmadmin,asmdba,asmoper grid useradd -u 6002 -g oinstall -G dba,asmadmin,asmdba oracle echo "oracle" |passwd --stdin grid echo "oracle" |passwd --stdin oracle
注意gird 和oracle的ID和group信息保持一致，如果共享磁盘用asmdba, 请确保oracle也在asmadm 组中
# id grid uid=6001(grid) gid=5001(oinstall) 组=5001(oinstall),5003(asmdba),5004(asmoper),5005(asmadmin) # id oracle uid=6002(oracle) gid=5001(oinstall) 组=5001(oinstall),5002(dba),5003(asmdba),5005(asmadmin)
如果grid和oracle group不一致用以下命令修正，再用id group 查看
usermod -g oinstall -G dba,asmadmin,asmdba oracle
6.创建目录 在RAC主机上(nymtx,hzmtx)
mkdir -p /oracle/app/grid mkdir -p /oracle/app/19c/grid chown -R grid:oinstall /oracle mkdir -p /oracle/app/oraInventory chown -R grid:oinstall /oracle/app/oraInventory mkdir -p /oracle/app/oracle/19c chown -R oracle:oinstall /oracle/app/oracle chmod -R 775 /oracle
7.设置grid 和oracle 用户环境 在RAC主机上(nymtx,hzmtx)
注意
1. 不同主机grid 用户上的ASM实例ORACE_SID要不一样， 一般用+ASM1， +ASM2,+ASM3, 以此类推
2. 不同主机的oracle用户，ORACLE_SID 可以不一样，但是ORACLE_UNQNAME要保持一致
３.为方便操作，各个主机机上grid和oracle 的ORACLE＿ＨＯＭＥ和ORACLE_BASE路经要保持一致。
主机 nymtx:
su - grid vi ~/.bash_profile umask 022 export CV_ASSUME_DISTID=RHEL7.6;export CV_ASSUME_DISTID export NLS_DATE_FORMAT="YYYY-MM-DD HH24:MI:SS"; export NLS_DATE_FORMAT export ORACLE_SID=+ASM1 export ORACLE_BASE=/oracle/app/grid export ORACLE_HOME=/oracle/app/19c/grid export TNS_ADMIN=$ORACLE_HOME/network/admin;export TNS_ADMIN export PATH=.:$PATH:$HOME/bin:$ORACLE_HOME/bin su - oracle vi ~/.bash_profile umask 022 export CV_ASSUME_DISTID=RHEL7.6;export CV_ASSUME_DISTID export NLS_DATE_FORMAT="YYYY-MM-DD HH24:MI:SS"; export NLS_DATE_FORMAT export ORACLE_BASE=/oracle/app/oracle export ORACLE_HOME=$ORACLE_BASE/product/19c/dbhome_1 export ORACLE_UNQNAME=mtxdb export ORACLE_SID=mtxdb1 export NLS_LANG=AMERICAN_AMERICA.ZHS16GBK export TNS_ADMIN=$ORACLE_HOME/network/admin;export TNS_ADMIN export PATH=.:$PATH:$HOME/bin:$ORACLE_HOME/bin
主机 hzmtx:
su - grid vi ~/.bash_profile umask 022 export CV_ASSUME_DISTID=RHEL7.6;export CV_ASSUME_DISTID export NLS_DATE_FORMAT="YYYY-MM-DD HH24:MI:SS"; export NLS_DATE_FORMAT export ORACLE_SID=+ASM2 export ORACLE_BASE=/oracle/app/grid export ORACLE_HOME=/oracle/app/19c/grid export TNS_ADMIN=$ORACLE_HOME/network/admin;export TNS_ADMIN export PATH=.:$PATH:$HOME/bin:$ORACLE_HOME/bin su - oracle vi ~/.bash_profile umask 022 export CV_ASSUME_DISTID=RHEL7.6;export CV_ASSUME_DISTID export NLS_DATE_FORMAT="YYYY-MM-DD HH24:MI:SS"; export NLS_DATE_FORMAT export ORACLE_BASE=/oracle/app/oracle export ORACLE_HOME=$ORACLE_BASE/product/19c/dbhome_1 export ORACLE_UNQNAME=mtxdb export ORACLE_SID=mtxdb2 export NLS_LANG=AMERICAN_AMERICA.ZHS16GBK export TNS_ADMIN=$ORACLE_HOME/network/admin;export TNS_ADMIN export PATH=.:$PATH:$HOME/bin:$ORACLE_HOME/bin
8.NFS Server 配置 主机 cnmtx
也可用UDEV来设定，详情参考https://www.cnblogs.com/tingxin/p/13177268.html
vi /etc/exports /asm *(rw,sync,no_wdelay,insecure,no_root_squash) systemctl restart nfs-server.service showmount -e exportfs -v 创建 共享磁盘 mkdir -p /asm/oracleasm/disks dd if=/dev/zero of=/asm/oracleasm/disks/asm1 bs=8192k count=1280 dd if=/dev/zero of=/asm/oracleasm/disks/asm2 bs=8192k count=1280 dd if=/dev/zero of=/asm/oracleasm/disks/asm3 bs=8192k count=1280 dd if=/dev/zero of=/asm/oracleasm/disks/asm4 bs=8192k count=1280 dd if=/dev/zero of=/asm/oracleasm/disks/asm5 bs=8192k count=1280 dd if=/dev/zero of=/asm/oracleasm/disks/asm6 bs=8192k count=128 dd if=/dev/zero of=/asm/oracleasm/disks/asm7 bs=8192k count=128
9.RAC挂载共享磁盘,并设置权限 在RAC主机上(nymtx,hzmtx)
mkdir /asm vi /etc/fstab 192.168.1.90:/asm /asm nfs rw,bg,hard,nointr,tcp,vers=3,timeo=600,rsize=32768,wsize=32768,actimeo=0 0 0 mount -a chown -R grid:asmadmin /asm/* chmod g+s /asm/*
