Manual Oracle startup and Common commands in Linux

Recently, my NC project runs in Linux. Write down the installation process.
============= Manually start Oracle ======## note: in this example, the oralce command is in the/home/oracle/product/10.2.0/db_1/bin directory. # You can change it to your own directory. 1. You need to set Environment Variables
$ Cd/home/oralce
$ Gedit. bash_profile
2. append the following statement:
Export ORACLE_BASE =/home/oracle
Export ORACLE_HOME = $ ORACLE_BASE/product/10.2.0/db_1
Export ORACLE_SID = orcl
Export PATH = $ PATH: $ ORACLE_HOME/bin
3. log out and Log On As an oracle user. The command to manually start oracle is:
# $ ORACLE_HOME/bin/dbstart
# $ ORACLE_HOME/bin/lsnrctl start
