Check software requirements 2.1 Check operating system version and kernel [root@oracle12c ~]# cat /etc/oracle -release Oracle Linux Server release 6.5 [root@oracle12c ~]# uname -r 3.8.13-16.2.1.el6uek.x86_642.2 Check whether the package is installed Use the command rpm -q package_name to check whether the package is installed, use the command yum -y install package_name installs packages online.

Create operating system users and groups 3.1 Create a group to check whether the group exists [root@oracle12c ~]# grep oinstall /etc/group [root@oracle12c ~]# grep dba /etc/group Create two groups, oinstall and dba [root @oracle12c ~]# /usr/sbin/groupadd oinstall [root@or http://www. wmem_max = 1048586 The two commented lines are added because the original file already exists and the setting value is larger than here. Enter the following command to make the change take effect: /sbin/sysctl -p 5. Set the resource limit of the installation user Log in to the root user, and add the content in /etc/security/limits.conf: oracle soft nofile 1024 oracle hard nofile 65536 oracle soft nproc 2047 oracle hard nproc 16384 oracle soft stack 10240 oracle hard stack 10240 Log in again as the oracle user to take effect. 6. Assign permissions to the /u01 directory [root@oracle12c ~]# chown -R oracle:oinstall /u01 [root@oracle12c ~]# chmod -R 775 /u01 7. Set environment variables for the oracle user Log in with the oracle user and execute [root@oracle12c ~]# vi ~/.bash_profile Add the following lines: TMP=/tmp; export TMPTMPDIR=$TMP; export TMPDIRORACLE_BASE=/u01/app/oracle; export ORACLE_BASEORACLE_HOME=$ORACLE_BASE/product/12.1.0/dbhome_1 ; export ORACLE_HOMEORACLE_SID=orcl; export ORACLE_SIDNLS_LANG=American_America.zhs16gbk;export NLS_LANGORA_NLS10=$ORACLE_HOME/nls/data;export ORA_NLS10TNS_ADMIN=$ORACLE_HOME/network/admin;export TNS_ADMINORACLE_TERM=xterm; export ORACLE_TERMPATH=/usr/sbin:$PATH; export PATHPATH=$ORACLE_HOME/bin:$PATH; export PATHLD_LIBRARY_PATH=$ORACLE_HOME/lib:/lib:/usr/lib; export LD_LIBRARY_PATHSHLIB_PATH=$LD_LIBRARY_PATH;export SHLIB_PATHCLASSPATH=$ORACLE_HOME/ jre:$ORACLE_HOME/jlib:$ORACLE_HOME/rdbms/jlib;export CLASSPATH Execute the following command to make the environment variable take effect: [oracle@oracle12c ~]$ source ~/.bash_profile 8. Install the database and create an instance to install the database using the graphical interface OUI And create instances and listeners (omitted). 9. Configure the database instance and monitor the automatic start After installing the Oracle database: Executing dbstart and dbshut will prompt: [oracle@oracle12c ~]$ dbstart ORACLE_HOME_LISTNER is not SET, unable to auto-start Oracle Net Listener Usage: /u01/app/ oracle/oracle/product/10.2.0/db_1/bin/dbstart ORACLE_HOME Because there is a problem with the setting of ORACLE_HOME_LISTNER in the dbstart and dbshut script files, open two files to find: ORACLE_HOME_LISTNER=$1, and modify it to ORACLE_HOME_LISTNER=$ORACLE_HOME: [oracle@ oracle12c ~]$ vi $ORACLE_HOME/bin/dbstart[oracle@oracle12c ~]$ vi $ORACLE_HOME/bin/dbshut save and exit after modification, the first problem has been solved;
