3. vi/etc/security/limits. conf
The following is the minimum recommended configuration.

Grid soft nproc 2047
Grid hard nproc 16384
Grid soft nofile 1024
Grid hard nofile 65536
If you find that the current value is greater. For example, if the number * represents all users and the current value is greater, you can set the number below.

4. vi/etc/pam. d/login

Session required pam_limits.so

5. Add a user and group groupadd oinstall
Groupadd dba useradd-g oinstall-G dba grid passwd grid
6. Create the $ ORACLE_BASE and ORACLE_HOME directories of the grid.
Mkdir-p/u02/grid
Mkdir-p/u02/11.2.0/grid
Chown-R grid: dba/u02
Chmod-R 775/u02

7. Add the grid user environment variable to. bash_profile. ORACLE_BASE =/u01/app/grid; export ORACLE_BASE
ORACLE_HOME =/u01/app/11.2.0/grid; export ORACLE_HOME
Export PATH = $ ORACLE_HOME/bin: $ PATH
Export ORACLE_SID = + ASM

8. download media

Upload the 11.2 GI software installation media, which can be downloaded from my cloud disk. Http://yunpan.cn/QNWwLFFkWizFc access password 2558 unzip p10404530_112030_Linux-x86-64_3of7_grid.zip cd grid [root @ erpp2 grid] # ls doc install readme.html response rpm runcluvfy. sh runInstaller sshsetup stage welcome.html
9. Initiate installation.

Users such as oracle and grid cannot run and install with root. Generally, we use grid to separate it from database users.

Enable vncserver

The vnc graphic interface is connected to the server, and the root user executes xhost +

Grid user executes./runInstaller

Because I installed asm on a single machine instead of a cluster, select the second one.

Select english.

Select external, which means that the ASM layer does not need to be mirrored. External means that the underlying storage is raid, and we do not need to create an image for ASM.

Enter a simple password. You can ignore it even if it is prompted.

Although I use a grid user independent from an oracle user, I have not created a new asmadmin group for the grid user, therefore, you can specify the oinstall or dba group (of course, the grid user must have the oinstall and dba groups)

Here, a default BASE and HOME are written based on the environment variable of the running user, namely the grid user.

Environment Variables of my grid users.

ORACLE_BASE =/u02/grid; export ORACLE_BASE

ORACLE_HOME =/u02/11.2.0/grid; export ORACLE_HOME

Export PATH = $ ORACLE_HOME/bin: $ PATH

Export ORACLE_SID = + ASM

Click Next To Go To The check procedure. After the check is completed, we can click install to install it.

After running, run the script as root.

Run the root script.

[Root @ erpdb dev] # sh/u02/11.2.0/grid/root. sh

Padding Ming root user operation for Oracle 11g

The following environment variables are set:

ORACLE_OWNER = grid

ORACLE_HOME =/u02/11.2.0/grid

Enter the full pathname of the local bin directory: [/usr/local/bin]:

Then click Next to complete the installation.

After that, use the grid user, sqlplus '/as sysasm' to check whether the diskgroup is mounted smoothly.
