第一部分，系统配置
修改主机名
[root@hostname ~]vim /etc/sysconfig/network
NETWORKING=yes HOSTNAME=rac1
修改hosts文件
[root@rac1 ~]# vim /etc/hosts
192.168.1.101 rac1 192.168.1.102 rac2 10.10.0.1 rac1-priv 10.10.0.2 rac2-priv 192.168.1.103 rac1-vip 192.168.1.104 rac2-vip 192.168.1.110 rac-scan
禁用防火墙
[root@rac1 ~]# service iptables stop
[root@rac1 ~]# chkconfig iptables off
禁用selinux
[root@rac1 ~]# vim /etc/selinux/config
SELINUX=disabled
修改/etc/pam.d/login
[root@rac1 ~]# vim /etc/pam.d/login
session required pam_limits.so
修改/etc/profile
[root@rac1 ~]# vim /etc/profile
if [ /$USER = "oracle" ] || [ /$USER = "grid" ]; then if [ /$SHELL = "/bin/ksh" ]; then ulimit -p 16384 ulimit -n 65536 else ulimit -u 16384 -n 65536 fi umask 022 fi
修改/etc/csh.login
[root@rac1 ~]# vim /etc/csh.login
if ( /$USER == "oracle" || /$USER == "grid" ) then limit maxproc 16384 limit descriptors 65536 endif
修改/etc/sysctl.conf
[root@rac1 ~]# vim /etc/sysctl.conf
fs.aio-max-nr = 1048576 fs.file-max = 6815744 #kernel.shmall = 2097152 #kernel.shmmax =42950000000 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[root@rac1 ~]# sysctl -p
为用户设置资源限制
[root@rac1 ~]# vim /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
配置CTSS
使用集群时间同步服务在集群中提供同步服务，需要卸载网络时间协议 (NTP) 及其配置。要停用 NTP 服务，必须停止当前的 ntpd 服务，从初始化序列中禁用该服务，并删除 ntp.conf 文件。
[root@rac1 ~]# /sbin/service ntpd stop
[root@rac1 ~]# chkconfig ntpd off
[root@rac1 ~]# mv /etc/ntp.conf /etc/ntp.conf.original
[root@rac1 ~]# rm /var/run/ntpd.pid
创建用户和组
[root@rac1 ~]# groupadd -g 501 oinstall
[root@rac1 ~]# groupadd -g 502 asmadmin
[root@rac1 ~]# groupadd -g 503 asmdba
[root@rac1 ~]# groupadd -g 504 asmoper
[root@rac1 ~]# groupadd -g 505 dba
[root@rac1 ~]# groupadd -g 506 oper
[root@rac1 ~]# useradd -m -u 1100 -g oinstall -G asmadmin,asmdba,asmoper -d /home/grid -s /bin/bash -c "Grid Infrastructure Owner" grid
[root@rac1 ~]# useradd -m -u 1101 -g oinstall -G dba,oper,asmdba -d /home/oracle -s /bin/bash -c "Oracle Software Owner" oracle
创建目录及授权
[root@rac1 ~]# mkdir -p /u01/app/grid
[root@rac1 ~]# mkdir -p /u01/app/11.2.0/grid
[root@rac1 ~]# chown -R grid:oinstall /u01
[root@rac1 ~]# mkdir -p /u01/app/oracle
[root@rac1 ~]# chown oracle:oinstall /u01/app/oracle
[root@rac1 ~]# chmod -R 775 /u01
修改用户环境变量
