Configure SSH Trust before installation
Configure the trust relationship with the Sshsetup script under the grid decompression directory.
Configure Oracle as well as the grid user and need to switch to the appropriate user to execute the script.
#./sshsetup/sshusersetup.sh–usergrid–hosts "Node1 Node2"
#./sshsetup/sshusersetup.sh–user oracle–hosts "Node1 Node2"

Perform pre-installation check scripts
Use the grid user to perform the runcluvfy.sh under the Software decompression directory.
./runcluvfy.sh Stage–pre Crsinst–n Node1,node2–fixup–verbose
An automatic fixup script is generated after the execution of the script, which can set the kernel parameters and so on.
/tmp/cvu_12.1.0.2.0_grid/runfixup.sh
The final output is shown in the appendix.
Here's the time to start the graphical interface.
installation process cluster Software Installation
Intercept only important parts
Patch is verified by the operating system engineer to have the latest version installed and can be ignored.
Because of the use of the private NIC binding technology, there is no use of Oracle's proposed HAIP technology, there is an error, can be ignored.
It is verified that several disk lunid are different, not the same disk, error ignored.
Because the DNS and DHCP are not used, and GNS is not used, the Hosts file is used to parse the scan alias, so there is an error and can be ignored.
This is a new version of 12c a bug, after checking that the status of IOCP is already available, so can be ignored.
Create a disk group
Then create the disk group
Install the database software to specify the installation directory can be verified, the installation of the grid software will appear the same warning, directly ignored.
Create a database
And finally the database is created.
Note here that there is a server pool concept, and the traditional 11g is not quite the same, it may be to prepare for large-scale clusters, where the cardinality, according to the original understanding of the number of machines, here to do is to allocate how many machine resources to the newly created server Pool, used for the newly created database. Because it is a dual machine, so here fill in 2. The other steps and the original are almost no longer listed here.
