Operating System Installation: CentOS_ 5.3
- For setup instructions under CentOS 5.2, see Operating System Installation: CentOS 5.2
Introduction
We chose to use CentOS 4.3 as our Linux software. It has the same versions of install packages supported by Oracle as Red Hat EL3, however it is free. You may choose to use another Linux flavor, although we strongly recommend using a version that is supported by Oracle. If you are using or going to use another flavor of Linux please do not skip reading the CentOS installation as it contains configurations needed to run Oracle properly. However, you may have to adjust these configurations changes for your version. We will go through the installation and configuration of CentOS and Oracle now.
CentOS 4.3 Installation
Install CentOS 4.3 -- You may want to tweak what does and does not get installed for each catagory.
X Window System GNOME Desktop Environment Editors Graphical Internet Text-based Internet Server Configuration Tools Development Tools Administration Tools System Tools
I've found it may not be necessary to install packages from GNOME and Graphical Internet, but if you have plenty of hdd space go ahead.
Set Kernel Parameters Modify the /etc/sysctl.conf file to include the lines appropriate to your operating system:
# Red Hat Enterprise Linux 4.0 and CentOS 4.x kernel.shmmax = 536870912 ! This number should equal 1/2 of the physical RAM in the machine. kernel.shmmni = 4096 kernel.shmall = 2097152 # semaphores: semmsl, semmns, semopm, semmni kernel.sem = 250 32000 100 128 fs.file-max = 65536 net.ipv4.ip_local_port_range = 1024 65000 net.core.rmem_default=262144 net.core.rmem_max=262144 net.core.wmem_default=262144 net.core.wmem_max=262144
Run the following command to change the current kernel parameters: /sbin/sysctl -p
Disable secure linux by editing the /etc/selinux/config file, making sure the SELINUX flag is set as follows: SELINUX=disabled Alternatively, this alteration can be done using the GUI tool (Applications > System Settings > Security Level). Click on the SELinux tab and disable the feature.
Setup -- I did a custom setup and didn't install gnome so I'm missing a few things. I just used 'yum install ......' to add missing packages. The documentation states that the following packages are required by the relevant operating systems:
- Red Hat Enterprise Linux 4.0 and CentOS 4.x
binutils-2.15.92.0.2-13 compat-db-4.1.25-9 -- not installed with default CentOS installation compat-libstdc++-296-2.96-132.7.2 control-center-2.8.0-12 -- not installed with default CentOS installation gcc-3.4.3-22.1 glibc-2.3.4-2.9 glibc-common-2.3.4-2.9 gnome-libs-1.4.1.2.90-44.1 -- not installed with default CentOS installation libaio-0.3.96 -- not installed with default CentOS installation libstdc++-3.4.3-22.1 libstdc++devel-3.4.3-22.1 make-3.79 openmotif21-2.1.30-11 -- not installed with default CentOS installation -- NOT SURE IF NEEDED by ORACLE. pdksh-5.2.14-30 setarch-1.6-1 sysstat-5.0.5-1 -- not installed with default CentOS installation -- IS NOT NEEDED by ORACLE xscreensaver-4.18-5.rhel4.2 -- IS NOT NEEDED by ORACLE
Choose the Server's Role
We are now ready to choose your server’s role and continue setup based on its role:
- Continue with instructions for development environment to compile HeroEngine Server Daemons
- Continue with instructions for setting up a HeroEngine Server
- Oracle Database
