Install Oracle 11g R2 process sharing under CentOS 7

I am not familiar with many Linux and so on, if there is wrong place also ask you to correct me. Thank you.

Planning to learn the Oracle,rman backup and restore function, so the virtual machine is installed, using the CENTOS7 x86_64-1611 version, Oracle is linux.x64_11g R2 version. Refer to blogs published by other people.

But in the process of step by step, still encountered many problems, organized as follows:

1, after the installation of CentOS, unable to access the network, the first thought is the virtual machine NIC configuration options have problems, consulted a lot of information, someone to adjust the host network sharing, and so on, and then did not solve the problem. After consulting colleagues, confirm that the reason is because the network card is not activated, virtual machine Select bridge mode, first use Nmtui to activate the NIC, configure the appropriate IP, the default gateway, etc., you can access the network normally. However, it is troublesome to activate every time after reboot, so find/etc/sysconfig/network-scripts/ifcfg-eth0 (ETH opening, not necessarily eth0), modify onboot=yes and connect the virtual machine's NIC IP, Gateway, DNS and other information are set up well. You can also access the extranet directly after rebooting.

2, the reference blog, one less step, log in with the root account, the permissions of the/USR/LOCAL/SRC directory open to Oracle users, and then use the Oracle user to upload the Oracle installation files to install. Then perform the extract command.

3, do not know is not the resolution of the Notebook, Oracle installed to 68% when the card master, but also do not see the error prompt window, can only see a small vertical line. This is deceptive. After pressing the ESC several times, the program continues to install.

4, the installation process, the corresponding address, password and other information is best to save.

5. First execution./runinstall command time, directly reported to Java class**** An error, query to the problem reason is unable to open the installation window. You can do this in the following ways:

Switch root Account

Export display=:0.0

Xhost +

Switch Oracle Account

Export display=:0.0

Xhost +

Then execute the runinstall command to open the installation window normally.
