oracle 10G RAC for redhat as5.3 安装说明 = 1、安装操作系统，建议分10G root如果是虚拟机，建议分1G的内存空间，磁盘空间为30G官方文档在AS4的推荐参数如下，同时注明若默认参数大于推荐值，则不要修改。semmsl 250semmns 32000semopm 100semmni 128shmmax Half the size of physical memory (in bytes)shmmni 4096shmall 2097152file-max 65536ip_local_port_range Minimum: 1024 Maximum:65000rmem_default 1048576rmem_max 1048576wmem_default 262144wmem_max 262144实际发现as5在参数上大多已超过推荐值实例如下：/etc/sysctl.conf.文件net.ipv4.ip_forward = 0net.ipv4.conf.default.rp_filter = 1net.ipv4.conf.default.accept_source_route = 0kernel.sysrq = 0kernel.core_uses_pid = 1net.ipv4.tcp_syncookies = 1kernel.msgmnb = 65536kernel.msgmax = 65536kernel.shmmax = 4294967295kernel.shmall = 268435456以上为系统默认值，以下为手动添加内容kernel.shmmni = 4096kernel.sem = 250 32000 100 128fs.file-max = 65536net.ipv4.ip_local_port_range = 1024 65000net.core.rmem_default = 1048576net.core.rmem_max = 1048576net.core.wmem_default = 262144net.core.wmem_max = 262144运行命令使配置生效：/sbin/sysctl p编辑/etc/security/limits.conf文件，添加如下内容，*号指所有用户，也可指定为oracle用户。* soft nproc 2047* hard nproc 16384* soft nofile 1024* hard nofile 65536编辑 /etc/pam.d/login 文件，如果以下内容不存在则添加session required /lib/security/pam_limits.so编辑 /etc/selinux/config文件SELINUX=disabled2、selinux 状态disable每台/etc/hosts 文件中添加记录10.80.10.251 ma-db-1192.168.100.100 ma-db1-priv10.80.10.248 ma-db1-vip10.80.10.252 ma-db-2192.168.100.200 ma-db2-priv10.80.10.249 ma-db2-vip3、安装redhat linux 5.3 的软件包rpm -Uvh setarch-2*rpm -Uvh make-3*rpm -Uvh glibc-2*rpm -Uvh libaio-0*rpm -Uvh compat-libstdc+-33-3*rpm -Uvh compat-gcc-34-3*rpm -Uvh compat-gcc-34-c+-3*rpm -Uvh gcc-4*rpm -Uvh libXp-1*rpm -Uvh openmotif-2*rpm -Uvh compat-db-4*4、建立组及用户groupadd oinstall -g 201groupadd dba -g 202groupadd oper -g 203useradd oracle -u 200 -g oinstall -G dba,operpasswd oracle建立目录mkdir -p /u01/crs/oracle/product/10.2.0/crsmkdir -p /u01/app/oracle/product/10.2.0/db_1chown -R oracle.oinstall /u015、oracle用户相互信任设置/home/oracle 路径下执行两台机器都需同样操作ssh db1 cat /home/oracle/.ssh/id_rsa.pub authorized_keysssh db1 cat /home/oracle/.ssh/id_dsa.pub authorized_keysssh db2 cat /home/oracle/.ssh/id_rsa.pub authorized_keysssh db2 cat /home/oracle/.ssh/id_dsa.pub authorized_keysscp authorized_keys db2:/home/oracle/.ssh/scp authorized_keys db1:/home/oracle/.ssh/编辑/etc/xinetd.d/rlogin文件把disable = yes改成disable = no保存退出service xinetd restarttouch /etc/hosts.equivchmod 600 /etc/hosts.equivchown root:root /etc/hosts.equiv编辑hosts.equiv文件添加如下内容：+db1 oracle+db2 oracle+db1-priv oracle+db2-priv oracle以oracle用户rlogin 、rcp测试一下即可。6、配置共享存储为共享磁盘建立分区，本文使用ASM，为ocr和vote建立两个300M分区（官方文档指明最少256M），然后建立一个或几个大的分区供asm使用即可。Fdisk /dev/sdb 分别建立sdb1分区和sdb2分区供ocr t和vote使用，sdb3供asm使用。Fdisk /dev/sdc 建立sdc1 供asm使用。编辑/etc/udev/rule.d/60-raw.rules文件，增加如下内容ACTION=add, KERNEL=sdb1, RUN+=/bin/raw /dev/raw/raw1 %NACTION=add, KERNEL=sdb2, RUN+=/bin/raw /dev/raw/raw2 %NACTION=add, KERNEL=sdb3, RUN+=/bin/raw /dev/raw/raw3 %NACTION=add, KERNEL=sdc1, RUN+=/bin/raw /dev/raw/raw4 %NKERNEL=raw1, OWNER=oracle, GROUP=oinstall, MODE=0600KERNEL=raw2, OWNER=oracle, GROUP=oinstall, MODE=0600KER
