Install Oracle 11gR2 (11.2.0.1) and basic configuration (1) on CentOS6.0, and centos6.011gr2
First install CentOS6.0. Install it. The only thing to note is the Checking the Software Requirements section in the Oracle 11G Installation guide, which requires Installation of some Software in the CentOS6 DVD image. You can configure the repos of a DVD image by yourself. The command format is as follows: rpm-qa | grep name binutils-2.17.50.0.6 okcompat-libstdc ++-33-3.2.3 okelfutils-libelf-0.125 okelfutils-libelf-devel-0.125 elfutils-libelf-devel-static-0.125 -- gcc-4.1.2 -- okglibc-2.5-24 okgcc-c ++-4.1.2 okglibc-common-2.5 okglibc-devel-2.5 okglibc-headers-2.5 okkernel-headers-2.6.18 okksh-20060214 oklibaio-0.3.106 oklibaio-devel-0.3.106 libgcc-4.1.2 oklibgomp-4.1.2 oklibstdc + +-4.1.2 oklibs Tdc ++-devel-4.1.2 okmake-3.81 oknumactl-devel-0.9.8.i386 sysstat-7.0.2 -- unixODBC-2.2.11 -- unixODBC-devel-2.2.11 -- CentOS-5.5-i386-bin-DVD.iso -- find the missing package from the \ CentOS file and upload it to linux, ls *. rpmrpm-ivh *. rpm CentOS6.0 Basic Environment configuration ==========## create dba and oinstall user groups.
