oracle11G 安装

一、新建oracle用户

[root@11g ~]# groupadd oinstall[root@11g ~]# groupadd dba[root@11g ~]# useradd -g oinstall -G dba oracle[root@11g ~]# echo "oracle" |passwd --stdin oracle

二、安装oracle所需的环境包（先配置好yum源）

[root@11g ~]# cat /etc/yum.repos.d/dvd.repo [server]name=serverbaseurl=file:///mnt/dvd/Serverenabled=1gpgcheck=0[root@11g ~]# ls /mnt/dvd/blafdoc.css     eula.py    README-en.html         ServerCluster         GPL        RELEASE-NOTES-en       supportinfoClusterStorage  p_w_picpaths     RELEASE-NOTES-en.html  TRANS.TBLEULA            isolinux   RPM-GPG-KEY            VTeula.en_US      README-en  RPM-GPG-KEY-oracle[root@11g ~]# yum -y install binutils compat-libstdc++-33 elfutils-libelf elfutils-libelf-devel glibc glibc-common glibc-devel gcc gcc-c++ libaio-devel libaio libgcc libstdc++ libstdc++-devel make sysstat unixODBC unixODBC-devel pdksh numactl-devel glibc-headers

三、修改linux内核参数

[root@11g ~]# tail -13 /etc/sysctl.conf （在文件尾部插入如下内容）#oracle 11Gfs.aio-max-nr = 1048576fs.file-max = 6815744kernel.shmall = 2097152kernel.shmmax = 4294967295kernel.shmmni = 4096kernel.sem = 250 32000 100 128net.ipv4.ip_local_port_range = 9000 65500net.core.rmem_default = 262144net.core.rmem_max = 4194304net.core.wmem_default = 262144net.core.wmem_max = 1048576[root@11g ~]# /sbin/sysctl -p （不重启使参数生效）

四、设置oracle用户打开文件的最大数

[root@11g ~]# tail -10 /etc/security/limits.conf （在文件尾部插入如下内容）#Oracle 11goracle soft nproc 2047oracle hard nproc 16384oracle soft nofile 1024oracle hard nofile 65536oracle soft stack 10240# End of file

五、修改登录配置

[root@11g ~]# tail -2 /etc/pam.d/login#Oracle 11gsession required pam_limits.so

六、配置主机名及hosts

[root@11g ~]# tail -1 /etc/sysconfig/networkHOSTNAME=11g.cubix.com[root@11g ~]# tail -1 /etc/hosts127.0.0.1       11g.cubix.com 11g

七、新建oracle安装目录

[root@11g ~]# mkdir -p /u01/app/oracle/product/11.2.0/db_1[root@11g ~]# chown -R oracle:oinstall /u01[root@11g ~]# chmod -R 755 /u01

八、修改oracle用户的环境变量

[root@11g ~]# su - oracle[oracle@11g ~]$ tail -5 .bash_profile#Oracle 11gexport ORACLE_SID=orcl                                  #数据库实例名export ORACLE_BASE=/u01/app/oracle                      #Oracle安装目录export ORACLE_HOME=$ORACLE_BASE/product/11.2.0/db_1     #Oracle家目录export PATH=$PATH:$ORACLE_HOME/bin                      #Path搜索路径[oracle@11g ~]$ source .bash_profile                    #刷新.bash_profile配置[oracle@11g ~]$ echo $ORACLE_SID                        #测试.bash_profile是否生效orcl

九、解压安装包

[oracle@11g src]$ unzip p10404530_112030_LINUX_1of7.zip [oracle@11g src]$ unzip p10404530_112030_LINUX_2of7.zip

十、开始安装数据库

[root@11g ~]# xhost +access control disabled, clients can connect from any host[root@11g ~]# su - oracle[oracle@11g ~]$ cd /usr/local/src/database/[oracle@11g database]$ ./runInstaller Starting Oracle Universal Installer...Checking Temp space: must be greater than 120 MB.
