ORACLE 11G RAC LINUX安装文档在RAC安装之前需要确认事宜：1.IP (VIP,PUBLIC IP,PRIVATE IP , SCAN IP )2. OCR,VOTINGDISK 2G 3.存储盘是否需要做多路径4.安装方式（ASM)1.系统检查查看OS版本：uname -a 查看虚拟内存：free查看临时文件：df -h /tmp df -h /dev/shm 查看内存：grep MemTotal /proc/Meminfogrep MemTotal /proc/Meminfo 查看IP：ifconfig -a 检查系统包：rpm -q --qf %{NAME}-%{VERSION}-%{RELEASE} (%{ARCH})\n binutils \compat-libstdc++-33 \elfutils-libelf \elfutils-libelf-devel \gcc \gcc-c++ \glibc \glibc-common \glibc-devel \glibc-headers \ksh \libaio \libaio-devel \libgcc \libstdc++ \libstdc++-devel \make \sysstat \unixODBC \unixODBC-devel检查多路径软件（查看存储多路径）/opt/bin/./dlnkmgr view -lu/opt/bin/./dlnkmgr view -patch (比较两边的盘符是否一致）查看存储读写是否一致ls -l sddlmad*dd if=/u01/test.txt of=/dev/sddlmaa1 bs=4096 count=2 cat /dev/sddlmaa1 (两主机分别执行，查看内容是否一致，不一致可以分别查看磁盘内容，直到看到相同的内容）2. 系统配置vi /etc/sysctl.confnet.core.rmem_default=262144net.core.rmem_max=4194304 net.core.wmem_default=262144net.core.wmem_max=1048576 net.ipv4.ip_local_port_range = 9000 65500fs.file-max = 6815744kernel.shmall = 134217728kernel.shmmax = 274877906944kernel.shmmni = 4096 kernel.sem = 250 32000 100 128fs.aio-max-nr=4194304#/sbin/sysctl –p使配置生效#/sbin/sysctl –a查看是否生效vi /etc/security/limits.confgrid soft nproc 2047grid hard nproc 16384grid soft nofile 1024grid hard nofile 65536oracle soft nproc 2047oracle hard nproc 16384oracle soft nofile 1024oracle hard nofile 65536vi /etc/pam.d/loginsession required pam_limits.sovi. /etc/profileif [ $USER = oracle ] || [ $USER = grid ]; thenif [ $SHELL = /bin/ksh ]; thenulimit -p 16384ulimit -n 65536elseulimit -u 16384 -n 65536fiumask 022fiFor the C shell (csh or tcsh)more /etc/csh.loginif ( $USER = oracle || $USER = grid ) thenlimit maxproc 16384limit descriptors 65536endif划分存储fdisk -l 更改磁盘属性chmod 660 /dev/sddlmaa1chmod 660 /dev/sddlmab1chown grid:asmadmin /dev/sddlmaa1chown grid:asmadmin /dev/sddlmab13.创建安装目录用户组及用户如果已存在用户，将其用户删除userdel oracleuserdel gridgroupdel oinstallgroupdel dbagroupdel asmadmingroupdel asmdbagroupdel asmoper如果已存在目录，将其目录删除rm -fr /home/orac
