1.2 detailed explanation of the installation process

Note that the installation of oracle needs to be installed in the graphical interface (you can also choose to install silently in command-line mode, which is very tedious and not recommended). You need to choose to install the graphical interface or install the graphical interface after the installation of the system.

The centos6.9 Desktop version is used this time.

1.2 installation process

1. Decompress the file

Cd / server/oracle/ unzip linuxx64_12201_database.zip

two。 Create an oracle user and switch to an oracle user

Useradd oraclepasswd oracle

Chown-R oracle.oracle / server/tools/database/

3. Switch to oracle user and configure environment variables

Su-oracle

Configure environment variables (under oracle users):

Vim .bash _ profile

# use for oracle

Export ORACLEBASE=/usr/oracle

Export ORACLEHOME=$ORACLEBASE/product

Export ORACLESID=orcl

Export PATH=$PATH:$HOME/bin:$ORACLEHOME/bin

Export LDLIBRARYPATH=$ORACLEHOME/lib:/usr/lib

4. Enter the installation directory and execute the installation script (under oracle user)

Cd / server//database

. / runInstaller

After running the above process, if you do not have the red installation interface below, do not panic, you may need to wait a while, if you do not want to wait, you can run again, if the above inspection conditions are not met, directly Baidu to find a way, do not repeat.

Note: when installing here, there may be an error: prvf-0002 cannot retrieve the local node name

In this case, the / etc/hosts file is not well written, and you need to add native parsing.

Format: static IP hostname

5. Configure the database and go to the web management page (multi-figure)

Enter your own email address (do not email me, thank you)

Choose to create a new database

Install Select Server Type

The desktop type has less functionality, so choose the server type.

Select the installation type of the database

You can select a single instance here

For installation, select advanced installation for customized installation.

Choose the database version here and select the enterprise version.

Specify the installation directory

Note that the installed directory should have enough space, and oracle needs more space.

Specify product list catalogue

Select the type of database to create

Select the database name, which is fine by default.

Pay attention to memory settings

Since I am a virtual machine, the memory is kept to a minimum.

Select utf8 in the character set

Select the example on the installation

Because I am for testing purposes, I install the samples

Select the way the data is stored

Cloud management, those with oracle can be added.

Data recovery, turning on

Set user password

I have a unified password here. It is recommended to set a high-strength password in the production environment.

It is relatively simple to set the password to oracle, and all systems will indicate that it does not comply with the security specification. Just choose Yes.

The type of database operation used (default)

Begin the installation.

Check to see if the environment is correct and there will be a fix script for the error.

Note: open the terminal to find the location of the script according to the prompt and use the repair script to fix it. Pay attention to the use of root users (ps: I have a problem with insufficient swap space expectation. I only have 2G at the beginning. I didn't give it well at the beginning. I found a way to increase the swap space. Baidu can find many ways. )

Run this script as the root user

After the repair is complete, you can continue the following operations.

Click the next step to install. The installation speed is slow. Wait patiently.

Execute the script during installation (as in the above script execution process, open the terminal, find a location and run these two scripts under the identity of root. _ when the second script is executed, there will be some selection information that can be defaulted throughout)

[root@oracle ~] # sh / oracle/app/oraInventory/orainstRoot.sh

Change permissions / oracle/app/oraInventory.

Add read and write permissions for the group.

Removes global read, write, and execute permissions.

Change the group name / oracle/app/oraInventory to oracle.

The execution of the script is complete.

[root@oracle ~] # sh / oracle/app/oraclea/product/12.2.0/dbhome_1/root.sh

When executing this script, just enter all the way (except for special needs).

Note: there is an error in the middle and the reason for the failure of Configuration Assistant (details can be judged by the log)

1. Check to see if the c:\ windows\ System32\ drivers\ etc\ hosts file 127.0.0.1 is blocked.

two。 And IP address do not use DHCP to automatically obtain IP, you need to specify an IP address. This problem error can be solved as long as you find the cause and let the monitor start normally.

3. The failure of the firewall to shut down caused

4. Check that other network configurations are correct.

When the installation is complete, use the browser to access it as prompted (the browser may report that the flash plug-in is missing and install one)

User name is system

The password I set is 123456.

The installation is complete at this point.

Some simple commands in command-line mode and the problems I encountered when using the command line for service deployment, as well as some differences between 12C and previous versions, will be posted on my next blog.
