安裝環(huán)境

cat /etc/redhat-release CentOS Linux release 7.7.1908 (Core)

在非OralceLinux環(huán)境下安裝，需要下載對(duì)應(yīng)平臺(tái)的rpm。

下載地址：

https://yum.oracle.com/repo/OracleLinux/OL7/latest/x86_64/index.html，搜索-19c下載最新版本即可。

安裝，首先執(zhí)行???????

[root@linuxtestb538 oracle]# rpm -ivh oracle-database-preinstall-19c-1.0-3.el7.x86_64.rpm warning: oracle-database-preinstall-19c-1.0-3.el7.x86_64.rpm: Header V3 RSA/SHA256 Signature, key ID ec551f03: NOKEYerror: Failed dependencies: bind-utils is needed by oracle-database-preinstall-19c-1.0-3.el7.x86_64 compat-libcap1 is needed by oracle-database-preinstall-19c-1.0-3.el7.x86_64 ksh is needed by oracle-database-preinstall-19c-1.0-3.el7.x86_64 smartmontools is needed by oracle-database-preinstall-19c-1.0-3.el7.x86_64 sysstat is needed by oracle-database-preinstall-19c-1.0-3.el7.x86_64????????xorg-x11-utils?is?needed?by?oracle-database-preinstall-19c-1.0-3.el7.x86_64

執(zhí)行出現(xiàn)缺少依賴錯(cuò)誤。

改用yum命令進(jìn)行安裝

安裝 Oracle 數(shù)據(jù)庫(kù)

yum install oracle-database-ee-19c-1.0-1.x86_64.rpm Installed:oracle-database-ee-19c.x86_64 0:1.0-1Complete!

配置數(shù)據(jù)庫(kù)

???????

配置好后設(shè)置當(dāng)前用戶下的環(huán)境變量

vi ~/.bashrc (打開(kāi)文件后追加oracle的環(huán)境變量信息)---------------------------------------------------export ORACLE_HOME=/opt/oracle/product/19c/dbhome_1 export ORACLE_SID=ORCLCDBexport PATH=$ORACLE_HOME/bin:$PATH--------------------------------------------------- 通過(guò)運(yùn)行source?~/.bashrc??（命令運(yùn)行后設(shè)置的環(huán)境變量生效）

驗(yàn)證安裝是否正確

su oracle (用戶切換到oracle用戶)sysplus / as sysdbaSQL*Plus: Release 19.0.0.0.0 - Production on Wed Nov 17 18:59:32 2021Version 19.3.0.0.0 Copyright (c) 1982, 2019, Oracle. All rights reserved.Connected to:Oracle Database 19c Enterprise Edition Release 19.0.0.0.0 - ProductionVersion 19.3.0.0.0 SQL>?

運(yùn)行以上命令 確認(rèn)Oracle數(shù)據(jù)庫(kù)是否能夠正確連接成功。

如果還不會(huì)裝，可以來(lái)參加微思的Oracle OCP課程，不但分分鐘教你安裝好數(shù)據(jù)庫(kù)，還能順便學(xué)到技術(shù)考好證書(shū)?
