虚拟机关机后,在srac1.vmx/srac2.vmx文件最后追加以下内容
#shared disks configure disk.EnableUUID="TRUE" disk.locking = "FALSE" scsi1.shared = "TRUE" diskLib.dataCacheMaxSize = "0" diskLib.dataCacheMaxReadAheadSize = "0" diskLib.dataCacheMinReadAheadSize = "0" diskLib.dataCachePageSize= "4096" diskLib.maxUnsyncedWrites = "0" scsi1.present = "TRUE" scsi1.virtualDev = "lsilogic" scsil.sharedBus = "VIRTUAL" scsi1:0.present = "TRUE" scsi1:0.mode = "independent-persistent" scsi1:0.fileName = "D:\vmware\sharedisk\Shared_Virtual_Disk_OCR1.vmdk" scsi1:0.deviceType = "disk" scsi1:0.redo = "" scsi1:1.present = "TRUE" scsi1:1.mode = "independent-persistent" scsi1:1.fileName = "D:\vmware\sharedisk\Shared_Virtual_Disk_OCR2.vmdk" scsi1:1.deviceType = "disk" scsi1:1.redo = "" scsi1:2.present = "TRUE" scsi1:2.mode = "independent-persistent" scsi1:2.fileName = "D:\vmware\sharedisk\Shared_Virtual_Disk_OCR3.vmdk" scsi1:2.deviceType = "disk" scsi1:2.redo = "" scsi1:3.present = "TRUE" scsi1:3.mode = "independent-persistent" scsi1:3.fileName = "D:\vmware\sharedisk\Shared_Virtual_Disk_FRA.vmdk" scsi1:3.deviceType = "disk" scsi1:3.redo = "" scsi1:4.present = "TRUE" scsi1:4.mode = "independent-persistent" scsi1:4.fileName = "D:\vmware\sharedisk\Shared_Virtual_Disk_DATA.vmdk" scsi1:4.deviceType = "disk" scsi1:4.redo = ""

安装
1. 关闭防火墙、SELinux
# chkconfig iptables off # chkconfig ip6tables off # vi /etc/selinux/config # This file controls the state of SELinux on the system. # SELINUX= can take one of these three values: # enforcing - SELinux security policy is enforced. # permissive - SELinux prints warnings instead of enforcing. # disabled - No SELinux policy is loaded. SELINUX=disabled # SELINUXTYPE= can take one of these two values: # targeted - Targeted processes are protected, # mls - Multi Level Security protection. SELINUXTYPE=targeted 重启后生效
2. 查看修改主机名
# hostname (查看hostname) # vi /etc/sysconfig/network (如果hostname不合适修改该文件) 建议在安装操作系统时设置合适的主机名
3. 修改/etc/hosts
# vi /etc/hosts增加以下内容 ##Public Network 92.0.2.101 srac1.example.com srac1 92.0.2.102 srac2.example.com srac2 ##Public Virtual IP (VIP) addresses 92.0.2.103 srac1-vip.example.com srac1-vip 92.0.2.104 srac2-vip.example.com srac2-vip ##Private Interconnect 192.168.0.101 srac1-priv.example.com srac1-priv 192.168.0.102 srac2-priv.example.com srac2-priv ##SCAN IP 92.0.2.105 srac-scan.example.com srac-scan
4. 创建用户和组
# /usr/sbin/groupadd -g 501 oinstall # /usr/sbin/groupadd -g 502 dba # /usr/sbin/groupadd -g 503 oper # /usr/sbin/groupadd -g 504 asmadmin # /usr/sbin/groupadd -g 505 asmoper # /usr/sbin/groupadd -g 506 asmdba # /usr/sbin/useradd -u 501 -g oinstall -G dba,oper,asmdba,asmadmin,asmoper grid # /usr/sbin/useradd -u 502 -g oinstall -G dba,oper,asmdba oracle # passwd grid # passwd oracle# id grid# id oracle
5. 配置内核参数
# vi /etc/sysctl.conf fs.aio-max-nr = 1048576 fs.file-max = 6815744 kernel.shmall = 4294967296 # kernel.shmmax/kernel.shmmni可以大不能小 kernel.shmmax = 68719476736 #超过memory_target,现在配置为64G kernel.shmmni = 4096 kernel.sem = 250 32000 100 128 #(PROCESSES+10 (PROCESSES+10)*128 PROCESSES+10 128) net.ipv4.ip_local_port_range = 9000 65500 net.core.rmem_default = 262144 net.core.rmem_max = 4194304 net.core.wmem_default = 262144 net.core.wmem_max = 1048576 # /sbin/sysctl -p 注:kernel.shmall= kernel.shmmax/ kernel.shmmni是理论值,一般设置偏大一点,按照kernel.shmmax/8设置即可 # vi /etc/security/limits.conf grid soft nproc 2047 grid hard nproc 16384 grid soft nofile 1024是 grid hard nofile 65536 oracle soft nproc 2047 oracle hard nproc 16384 oracle soft nofile 1024 oracle hard nofile 65536 # vi /etc/pam.d/login session required pam_limits.so # vi /etc/profile if [ $USER = "oracle" ] || [ $USER = "grid" ]; then if [ $SHELL = "/bin/ksh" ]; then ulimit -p 16384 ulimit -n 65536 else ulimit -u 16384 -n 65536 fi umask 022 fi
6. 停止NTP服务
# /sbin/service ntpd stop # service ntpd status # mv /etc/ntp.conf /etc/ntp.conf.bak 停用NTP服务后,grid组件安装时会自动启用oracle自带的时钟同步服务。
7. 增加/dev/shm大小
大小要超过memery_target # mount -o remount,size=4G /dev/shm # vi /etc/fstab tmpfs /dev/shm tmpfs defaults,size=4G 0 0
8. 创建目录并修改权限
# mkdir -p /u01/app/oracle # mkdir -p /u01/app/grid # mkdir -p /u01/app/11.2.0/grid # chown -R grid:oinstall /u01/app/grid # chown -R grid:oinstall /u01/app/11.2.0 # chown -R oracle:oinstall /u01/app/oracle # chmod -R 775 /u01 # mkdir -p /u01/app/oraInventory # chown -R grid:oinstall /u01/app/oraInventory # chmod -R 775 /u01/app/oraInventory
9. 修改环境变量
# su – grid $ vi .bash_profile export ORACLE_SID=+ASM1 export ORACLE_BASE=/u01/app/grid export ORACLE_HOME=/u01/app/11.2.0/grid export LD_LIBRARY_PATH=$ORACLE_HOME/lib:$ORACLE_HOME/lib32 export NLS_DATE_FORMAT="yyyy-mm-dd HH24:MI:SS" export NLS_LANG=American_america.ZHS16GBK export PATH=$ORACLE_HOME/bin:$PATH $ source .bash_profile# su - oracle$ vi .bash_profileexport ORACLE_SID=xdja1export ORACLE_BASE=/u01/app/oracleexport ORACLE_HOME=$ORACLE_BASE/product/11.2.0/dbhome_1export LD_LIBRARY_PATH=$ORACLE_HOME/lib:$ORACLE_HOME/lib32export NLS_DATE_FORMAT="yyyy-mm-dd HH24:MI:SS"export NLS_LANG=American_america.ZHS16GBKexport PATH=$PATH:$ORACLE_HOME/bin$ source .bash_profile注:srac2节点上需要把红色部分分别改为对应的+ASM2和xdja2;oracle用户的ORACLE_SID按照规划的实例名进行相应设置,例如规划实例名为xdja,这里的ORACLE_SID分别设置为xdja1/xdja2
10. 安装依赖包
首先配置本地yum源,软后使用yum命令安装所有依赖包 # yum -y install binutils compat-libcap1 compat-libstdc++-33 elfutils-libelf-devel gcc gcc-c++ glibc glibc-devel ksh libgcc libstdc++ libstdc++-devel libaio libaio-devel make sysstat unixODBC unixODBC-devel libXp parted vim xorg-x11-utils xorg-x11-xauth unzip
11. 配置共享存储
查看是否认出前面配置的共享磁盘 # ll /dev/sd* 查出每块共享磁盘的wwid # scsi_id --whitelisted --replace-whitespace --device=/dev/sdb 36000c29cc2059bd2971fa2c85def1bb7 # scsi_id --whitelisted --replace-whitespace --device=/dev/sdc 36000c29291defedaa634a5b6edcf005d # scsi_id --whitelisted --replace-whitespace --device=/dev/sdd 36000c29b22662652d2aed62610921779 # scsi_id --whitelisted --replace-whitespace --device=/dev/sde 36000c297efa48942f5c92f20c5301103 # scsi_id --whitelisted --replace-whitespace --device=/dev/sdf 36000c295385cc5aec648a12c665d88e0 根据wwid对共享磁盘进行绑定 # vim /etc/udev/rules.d/99-oracle-asmdevices.rules KERNEL=="sd*", BUS=="scsi", PROGRAM=="/sbin/scsi_id --whitelisted --replace-whitespace --device=/dev/$name",RESULT=="36000c29cc2059bd2971fa2c85def1bb7", NAME="asm-diskb", OWNER="grid",GROUP="oinstall", MODE="0660" KERNEL=="sd*", BUS=="scsi", PROGRAM=="/sbin/scsi_id --whitelisted --replace-whitespace --device=/dev/$name",RESULT=="36000c29291defedaa634a5b6edcf005d", NAME="asm-diskc", OWNER="grid",GROUP="oinstall", MODE="0660" KERNEL=="sd*", BUS=="scsi", PROGRAM=="/sbin/scsi_id --whitelisted --replace-whitespace --device=/dev/$name",RESULT=="36000c29b22662652d2aed62610921779", NAME="asm-diskd", OWNER="grid",GROUP="oinstall", MODE="0660" KERNEL=="sd*", BUS=="scsi", PROGRAM=="/sbin/scsi_id --whitelisted --replace-whitespace --device=/dev/$name",RESULT=="36000c297efa48942f5c92f20c5301103", NAME="asm-diske", OWNER="grid",GROUP="oinstall", MODE="0660" KERNEL=="sd*", BUS=="scsi", PROGRAM=="/sbin/scsi_id --whitelisted --replace-whitespace --device=/dev/$name",RESULT=="36000c295385cc5aec648a12c665d88e0", NAME="asm-diskf", OWNER="grid",GROUP="oinstall", MODE="0660" 重启udev,使配置生效 # start_udev
