Problems encountered
Checked the log
No error reports of error level were found
Execute / bin/sh
Finally, the installation succeeded
Execute the script as required.
Open the terminal, log in as root, and execute the script:

Conduct instance check
View listening status:
Database creation completed.
For more information, check the log file: / data / Oracle / cfgtoollogs / DBCA / orcl / orcl log.
Login to view instance status:

It seems to have been installed
Use oralce after startup
cd /home/oracle/app/oracle/product/11.2.0/dbhome_1/ sh root.sh source /home/oracle/.bash_profile lsnrctl status lsnrctl start su oracle source /home/oracle/.bash_profile lsnrctl start sqlplus / as sysdba startup lsnrctl sqlplus /nolog conn /as sysdba; create user admin identified by 123456; grant connect,resource,dba to admin;
After successfully installing oracle, create a login account
1. Switch to oracle user
su -l oracle
2. Login with sysdba account:
sqlplus / as sysdba
3. Create user
Syntax: CREATE USER username IDENTIFIED BY password;
CREATE USER admin IDENTIFIED BY admin;
4. Unlock / lock the newly created user
Syntax: ALTER USER username ACCOUNT UNLOCK/LOCK
//User unlock
```
alter user mmzsit account unlock;
//User locked
alter user admin account lock;
//User unlock
alter user admin account unlock;
4,Grant the newly logged in user creation permission: Syntax: CRANT CREATE SESSION TO user name ```js grant create session to admin;
5. Grant database administrator privileges to newly created users
Syntax: Crane DBA to user name;
grant dba to admin;
6. Switch to the newly created user login
Syntax: CONNECT username / password
connect admin/admin;
Install Oracle 11g Online

First put the package in / install/oracle11G
cd /install/oracle11G unzip unzip linux_11gR2_database_1of2.zip unzip unzip linux_11gR2_database_1of2.zip
Install oracle server software

Adjust kernel parameters and user restrictions
[root@localhost etc]# vim /etc/sysctl.conf //Add information fs.aio-max-nr = 1048576 fs.file-max = 6815744 kernel.shmall = 2097152 kernel.shmmax = 536870912 kernel.shmmni = 4096 kernel.sem = 250 32000 100 128 net.ipv4.ip_local_port_range = 9000 65500 net.core.rmem_default = 262144 net.core.rmem_max = 4194304 net.core.wmem_default = 262144 net.core.wmem_max = 1048586
Edit / etc / security / limits Conf file to modify the restrictions of the operating system on oracle user resources. Add the following line to the file.
[root@localhost ~]# vim /etc/security/limits.conf //Add to # End of file oracle soft nproc 2047 oracle hard nproc 16384 oracle soft nofile 1024 oracle hard nofile 65536 oracle hard stack 10240
Turn on operating system asynchronous IO (AIO)
The package to be installed in point 2 above already contains libaio-0.3.106. Asynchronous I/O is enabled by default.
Check whether AIO is running in the operating system. The running command and display results are similar as follows:
$ cat /proc/slabinfo | grep kio kioctx 51 120 320 12 1 : tunables 54 27 8 : slabdata 10 10 0 kiocb 30 30 256 15 1 : tunables 120 60 8 : slabdata 2 2 0
Note: if the database uses a file system and asynchronous IO is used, the initialization parameters of the database need to be modified
a. Set disk_asynch_io parameter value is TRUE (default value)
b. Set filesystemio_ The value of options parameter is ASYNCH
