11g oracle rac udev 安装配置 11g oracle udev rac安装配置1、环境准备 1）解析主机名称 ######public####### 192.168.11.10 rac1 192.168.11.30 rac2 #######private##### 192.168.56.10 rac1-prv 192.168.56.30 rac2-prv ######vip######### 192.168.11.12 rac1-vip 192.168.11.32 rac2-vip 2）关闭防火墙、seliunx service iptables stop chkconfig iptables off service iptables status chkconfig iptables --list sed -i '/SELINUX/s/enforcing/disabled/' /etc/selinux/config sestatus 3)配置主机名称 vi /etc/sysconfig/network NETWORKING=yes HOSTNAME=rac1 4)yum源的配置 4.1）将镜像挂载 #mount /dev/cdrom /mnt 4.2)修改yum源的配置文件 # vi /etc/yum.repos.d/CentOS-Base.repo [base] name=CentOS6.6-Base #mirrorlist=http://mirrorlist.centos.org/?release=$releasever&arch=$basearch&repo=os&infra=$infra baseurl=file:///mnt gpgcheck=1 enable=1 gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-6 4.3、#yum clean all 4.4、安装oracle需要的rpm包
5)dns解析scanip 节点一: 5.1)配置DNS服务 挂载上镜像文件，yum配置好，安装DNS服务 #yum install bind -y #yum install bind-chroot -y 5.2)配置dns解析scanip，达到负载均衡的效果。 配置如下： 1、配置dns服务文件 # vi /var/named/chroot/etc/named.conf options { directory "/var/named"; };
zone "oracle.com" IN { type master; file "oracle.com.zone"; zone "11.168.192.in-addr.arpa" IN { file "0.zone"; 2、配置dns解析文件 #vi /var/named/chroot/var/named/oracle.com.zone
$TTL 86400 @ IN SOA dns.oracle.com. root.oracle.com ( 130830; 3H; 15M; 1W; 1D) IN NS dns.oracle.com. dns IN A 192.168.11.10 #自己服务器主机的ip地址 scan IN A 192.168.11.31 scan IN A 192.168.11.32 scanIN A 192.168.11.33 3、配置dns反解析文件 #vi /var/named/chroot/var/named/0.zone 130830; 31 IN PTR scan.oracle.com. 32 IN PTR scan.oracle.com. 33 IN PTR scan.oracle.com.
4、重启dns服务 service named restart chkconfig named on 5、节点二： 客户端DNS配置 编辑/etc/resolv.conf文件 vi /etc/resolv.conf nameserver 192.168.11.10 --我们刚才添加的DNS Server（也就是节点一的rac1的ip地址） 6、将dns配置在网卡上 vi /etc/sysconfig/network-scripts/ifcfg-eth0 DEVICE=eth0 HWADDR=08:00:27:7e:60:82 TYPE=Ethernet UUID=fd25d479-e2f6-43a6-a3b3-3363533e037d ONBOOT=yes NM_CONTROLLED=yes BOOTPROTO=none IPADDR=192.168.11.10 NETMASK=255.255.255.0 GATEWAY=192.168.11.1 DNS1=192.168.11.10 IPV6INIT=no USERCTL=no 重启网卡 service network restart 6、验证dns nslookupscan.oracle.com 6)修改内核参数 vi/etc/sysctl.conf fs.file-max = 6815744 fs.aio-max-nr=1048576 kernel.shmall = 2097152 kernel.shmmax = 2147483648 kernel.shmmni = 4096 kernel.sem = 250 32000 100 128 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立即生效
注意：在其他节点重复内核参数的操作 7）限制参数 /etc/security/limits.conf grid soft nproc 2047 grid hard nproc 16384 grid soft nofile 1024 grid hard nofile 65536 oracle soft nproc 2047 oracle hard nproc 16384 oracle soft nofile 1024 oracle hard nofile 65536 8)修改全局变量 vi/etc/profile if [ $USER = "oracle" ] || [ $USER = "grid" ]; then if [ $SHELL = "/bin/ksh" ]; then ulimit -p 16384 ulimit -n 65536 else ulimit -u 16384 -n 65536 fi umask 022 fi source /etc/profile --生效 9）创建用户 groupadd -g 1000 oinstall groupadd -g 1002 dba groupadd -g 1001 oper groupadd -g 1010 asmadmin groupadd -g 1011 asmoper groupadd -g 1012 asmdba useradd -u 1012 -g oinstall -G asmadmin,asmdba,asmoper,dba grid useradd -u 1002 -g oinstall -G dba,oper,asmdba oracle passwd oracle passwd grid 10）创建目录 mkdir -p /u01/app/11.2.0/grid mkdir -p /u01/app/grid chown -R grid:oinstall /u01 mkdir /u01/app/oracle chown oracle:oinstall /u01/app/oracle chmod -R 775 /u01/ 11）环境变量 vi .bash_profile文件 export ORACLE_SID=+ASM1 export ORACLE_BASE=/u01/app/grid export ORACLE_HOME=/u01/app/11.2.0/grid export LD_LIBRARY_PATH=$ORACLE_HOME/lib export NLS_DATE_FORMAT="yyyy-mm-dd HH24:MI:SS" export PATH=$ORACLE_HOME/bin:$PATH Oracle用户的环境变量设置 在oracle的家目录下/home/oracle vi .bash_profile文件 export ORACLE_BASE=/u01/app/oracle export ORACLE_HOME=$ORACLE_BASE/product/11.2.0/dbhome_1 export CRS_HOME=/u01/app/oracle/crs_1 export PATH=$HOME/bin:$CRS_HOME/bin:$ORACLE_HOME/bin:$PATH export ORACLE_OWNER=oracle export ORACLE_SID=DAAS1 export LD_LIBRARY_PATH=$ORACLE_HOME/lib:/lib:/usr/lib 12）安装所需要的rpm（所有节点安装） [root@rac1 soft]# rpm

将配置文件传输到rac2节点 scp/etc/udev/rules.d/99-oracle-asmdevices.rulesrac2:/etc/udev/rules.d/ 3）在node1,node2上重新启动udev start_udev 4）验证asm ls -al /dev/asm* 3、GI安装
到100%的时候报错，可以直接点击OK，然后skip。查看日志发现几个error， INFO: Checking name resolution setup for "dbscan"... INFO: ERROR: INFO: PRVG-1101 : SCAN name "dbscan" failed to resolve INFO: ERROR: INFO: PRVF-4657 : Name resolution setup check for "dbscan" (IP address: 192.168.16.30) failed INFO: ERROR: INFO: PRVF-4664 : Found inconsistent name resolution entries for SCAN name "dbscan" INFO: Verification of SCAN VIP and Listener setup failed INFO: Checking OLR integrity...

INFO: OLR file check successful INFO: WARNING: INFO: PRVF-4664 : Found inconsistent name resolution entries for SCAN name "dbscan" INFO: Verification of SCAN VIP and Listener setup failed 这个错误是scan解析失败，在os中ping一下scanip和scan name如果能ping通的话，那就没问题，直接ok，然后skip
