安装前的准备工作
修改主机名
#NODE1 [root@localhost ~]# vi /etc/sysconfig/network NETWORKING=yes HOSTNAME=node1 #NODE2 [root@localhost ~]# vi /etc/sysconfig/network NETWORKING=yes HOSTNAME=node2
修改/etc/hosts
[root@node2 ~]# vi /etc/hosts #NODE1 192.168.11.101 node1 192.168.11.103 node1-vip 192.11.80.101 node1-priv #node2 192.168.11.102 node2 192.168.11.104 node2-vip 192.11.80.102 node2-priv #scan 192.168.11.105 ctcsdoc-scan [root@node1 ~]# vi /etc/hosts #NODE1 192.168.11.101 node1 192.168.11.103 node1-vip 192.11.80.101 node1-priv #node2 192.168.11.102 node2 192.168.11.104 node2-vip 192.11.80.102 node2-priv #scan 192.168.11.105 ctcsdoc-scan
关闭防火墙
service iptables stop service ip6tables stop chkconfig iptables off chkconfig ip6tables off chkconfig iptables --list
禁用SELINUX
[root@node2 ~]# vi /etc/selinux/config SELINUX=disabled [root@node1 ~]# vi /etc/selinux/config SELINUX=disabled [root@node1 ~]# setenforce 0 [root@node1 ~]# getenforce Permissive [root@node2 ~]# setenforce 0 [root@node2 ~]# getenforce Permissive
添加用户、用户组并修改密码

创建安装目录
mkdir -p /u01/app/oracle mkdir -p /u01/app/grid mkdir -p /u01/app/11.2.0/grid mkdir -p /u01/app/oracle/product/11.2.0/dbhome_1 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
配置用户的环境变量文件

修改系统配置文件
--修改/etc/sysctl.conf 文件 # for oracle fs.aio-max-nr = 1048576 fs.file-max = 6815744 kernel.shmall = 2097152 kernel.shmmax = 161061273600 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 = 1048586 修改rac相关用户对shell的限制 vi /etc/security/limits.conf oracle soft nproc 2047 oracle hard nproc 16384 oracle soft nofile 1024 oracle hard nofile 65536 grid soft nproc 2047 grid hard nproc 16384 grid soft nofile 1024 grid hard nofile 65536 修改/etc/pam.d/login 文件 echo "session required pam_limits.so" >> /etc/pam.d/login
关闭NTP
查看一下两节点时间是否相差太大，如果相差不大则不用调整，如果相差较大则需要调整时间，否则ctss需要运行很久才能使两节点一致
/sbin/service ntpd stop mv /etc/ntp.conf /etc/ntp.conf.bak service ntpd status chkconfig ntpd off
使用udev创建共享磁盘
multipath 命令查看当前可以使用的多路径磁盘
