系统环境与分区规划：
服务器为VMware虚拟化环境，分配6G内存、2个vCPU、100G硬盘 硬盘分区情况为： /boot 100M / 20G /home 20G /opt 20G （安装oracle软件和其他第三方软件） /oracle 40G （存放oracle数据）Redhat5.5安装oracle11g
RHEL5.5 为默认安装，我的hostname起名为redhat5,
首先安装Oracle11g所需要的补丁包,安装光盘上全有,进入光盘的Server目录： [root@redhat5 Server]# rpm -Uvh binutils-2.17.50.0.6-14.el5.i386.rpm [root@redhat5 Server]# rpm -Uvh compat-libstdc++-33-3.2.3-61.i386.rpm [root@redhat5 Server]# rpm -Uvh elfutils-libelf-0.137-3.el5.i386.rpm [root@redhat5 Server]# rpm -ivh --nodeps elfutils-libelf-devel-0.137-3.el5.i386.rpm [root@redhat5 Server]# rpm -Uvh elfutils-libelf-devel-static-0.137-3.el5.i386.rpm [root@redhat5 Server]# rpm -Uvh --nodeps gcc-4.1.2-48.el5.i386.rpm [root@redhat5 Server]# rpm -Uvh libstdc++-4.1.2-48.el5.i386.rpm [root@redhat5 Server]# rpm -Uvh libstdc++-devel-4.1.2-48.el5.i386.rpm [root@redhat5 Server]# rpm -Uvh gcc-c++-4.1.2-48.el5.i386.rpm [root@redhat5 Server]# rpm -Uvh glibc-2.5-49.i686.rpm [root@redhat5 Server]# rpm -Uvh glibc-common-2.5-49.i386.rpm [root@redhat5 Server]# rpm -Uvh kernel-headers-2.6.18-194.el5.i386.rpm [root@redhat5 Server]# rpm -Uvh glibc-headers-2.5-49.i386.rpm [root@redhat5 Server]# rpm -Uvh glibc-devel-2.5-49.i386.rpm [root@redhat5 Server]# rpm -Uvh ksh-20100202-1.el5.i386.rpm [root@redhat5 Server]# rpm -Uvh libaio-0.3.106-5.i386.rpm [root@redhat5 Server]# rpm -Uvh libaio-devel-0.3.106-5.i386.rpm [root@redhat5 Server]# rpm -Uvh libgcc-4.1.2-48.el5.i386.rpm [root@redhat5 Server]# rpm -Uvh libgomp-4.4.0-6.el5.i386.rpm [root@redhat5 Server]# rpm -Uvh libstdc++-4.1.2-48.el5.i386.rpm [root@redhat5 Server]# rpm -Uvh libstdc++-devel-4.1.2-48.el5.i386.rpm [root@redhat5 Server]# rpm -Uvh make-3.81-3.el5.i386.rpm [root@redhat5 Server]# rpm -Uvh sysstat-7.0.2-3.el5.i386.rpm [root@redhat5 Server]# rpm -Uvh unixODBC-2.2.11-7.1.i386.rpm [root@redhat5 Server]# rpm -Uvh unixODBC-devel-2.2.11-7.1.i386.rpm 创建Oracle用户，密码自己填。 [root@redhat5 Server]# /usr/sbin/groupadd oinstall [root@redhat5 Server]# /usr/sbin/groupadd dba [root@redhat5 Server]# /usr/sbin/useradd -g oinstall -G dba oracle [root@redhat5 Server]# passwd oracle Changing password for user oracle. New UNIX password:BAD PASSWORD: it is based on a dictionary word
Retype new UNIX password:passwd: all authentication tokens updated successfully.
修改 /etc/sysctl.conf 文件，加上如下参数 fs.aio-max-nr = 1048576 fs.file-max = 6815744 kernel.shmall = 2097152 kernel.shmmax = 536870912 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 应用配置 # /sbin/sysctl -p 修改用户限制 修改 /etc/security/limits.conf 文件，加上下面的参数 oracle soft nproc 2047 oracle hard nproc 16384 oracle soft nofile 1024 oracle hard nofile 65536 修改用户验证选项 修改/etc/pam.d/login文件加上如下参数 session required pam_limits.so 修改用户配置文件 修改/etc/profile文件加入如下参数： if [ $USER = "oracle" ]; then if [ $SHELL = "/bin/ksh" ]; then ulimit -p 16384 ulimit -n 65536 else ulimit -u 16384 -n 65536 fi fi 安装目录配置 # mkdir -p /u01/ # chown -R oracle:oinstall /u01/ # chmod -R 775 /u01/ 修改用户bash shell #su - oracle $ vi .bash_profile 增加以下内容，注意：orcl为oracle数据库的实例名。export ORACLE_BASE=/u01/app export ORACLE_HOME=$ORACLE_BASE/oracle export ORACLE_SID=orcl export PATH=$ORACLE_HOME/bin:$PATH:$HOME/bin 安装oralce,把oracle安装文件从windows机器D盘上拷贝过来安装。 #mkdir /mnt/smb #mount //IP地址/D$ /mnt/smb –o username=administrator%密码 #cd /mnt/smb #cp linux_11gR2_database_1of2.zip /tmp #cp linux_11gR2_database_2of2.zip /tmp #umount /mnt/smb #cd /tmp #unzip linux_11gR2_database_1of2.zip /tmp #unzip linux_11gR2_database_2of2.zip /tmp 改用oracle用户登录Redhat5.5安装 $cd /tmp/database 改为1024*768分辨率 $./runInstaller 然后启动图形界面安装。
