環境：

OEL 6.8

DB：18.3

安裝過程中包括兩個RPM包

oracle-database-ee-18c-1.0-1.x86_64.rpm

oracle-database-preinstall-18c-1.0-1.el7.x86_64.rpm

安裝過程分為線上安裝和離線安裝，決定於oracle-database-preinstall-18c-1.0-1.el7.x86_64.rpm。

線上安裝：

# curl -o oracle-database-preinstall-18c-1.0-1.el7.x86_64.rpm

# yum -y localinstall oracle-database-preinstall-18c-1.0-1.el7.x86_64.rpm

離線安裝，下載oracle-database-preinstall-18c-1.0-1.el7.x86_64.rpm後，手動安裝。

下載地址：

該過程採取離線安裝，下載軟體包：

oracle-database-preinstall-18c-1.0-1.el7.x86_64.rpm軟體包檢查系統軟體包，調整系統引數，新增資料庫使用者組和使用者

透過shell指令碼定製Oracle安裝條件，實現最佳安裝環境配置。

[INFO] Executing post installation scripts...

[INFO] Oracle home installed successfully and ready to be configured.

To configure a sample Oracle Database you can execute the following service configuration script as root: /etc/init.d/oracledb_ORCLCDB-18c configure

檢查檔案內容：

/etc/init.d/oracledb_ORCLCDB-18c 檔案中configure方法內容如下

......

configure()

{

check_for_configuration

RETVAL=$?

if [ $RETVAL -eq 0 ]

then

echo "Oracle Database instance $ORACLE_SID is already configured."

exit 1

fi

read_config_file

check_port_availability

check_em_express_port_availability

configure_perform

}

......

該檔案包括資料庫啟動、停止、重啟等相關指令碼集合。

[root@oeldb ~]# more /etc/init.d/oracledb_ORCLCDB-18c | grep '()'

start()

stop()

configure_perform()

unset_proxy_vars()

check_for_configuration()

read_config_file()

configure()

check_port_availability()

check_em_express_port_availability()

restart()

建立資料庫，預設建立sid:ORCLCDB,pdb_name:ORCLPDB1,可根據要求調整檔案內容。
