大家好,我是 JiekeXu,很高兴又和大家见面了,今天分享下 Oracle 19c 之 RPM 包安装初体验。 本文首发于微信公众号【JiekeXu之路】,欢迎点击上方蓝字关注我吧!
Oracle 自18c 开始,便已经提供Linux 环境单机的 rpm 安装方式,不过仅支持单实例安装,不支持集群,也只有企业版,其他版本的没有发布,不过有2.5 G 大小。
昨天在墨天轮数说里,看到恩墨盖总发的 Oracle 数据库的产品支持生命周期又有更新了。大概是说Oracle 19c 的支持期继续延展了,这样相当于有七年的支持时间,可以获得技术支持和补丁支持,是目前最值得安装的版本。12c、18c、20c 这些都是过渡版本,生命周期比较短暂。Oracle 20c 原计划今年 6 月发布但也尚未浮出水面,估计因为疫情的影响,Oracle 20c 今年极有可能不做正式发布了,随着 OOW 大会的临近,Oracle 21c 的信息即将会展示出来,敬请期待吧。
原文 Release Schedule of Current Database Releases (Doc ID 742060.1) 于 2020.6.16 日更新了,有账号的伙伴可以去查看。
安装检查过程
下面根据官方文档一起看看安装过程和检查步骤
https://docs.oracle.com/en/database/oracle/oracle-database/19/ladbi/index.html
首先操作系统版本要求 Oracle Linux7.4、RedHat 7.5 或者 SUSE Linux Enterprise Server12 SP3以上版本,我这里的版本是 RedHat 7.4 勉强可以凑合安装,Linux 6 已经不在支持范围内了。
检查磁盘空间,Linux 企业版需要至少 7.2 G 的空间
更多环境检查步骤请查看上文官方文档链接即可,下面来看看软件下载。
软件下载
在 Oracle 官网上便可以轻松下载如下软件包,你只需要注册一个账号即可,如果你没有账号,不知道怎么下载,没关系,我这里下载好了,公众号[ID:JiekeXu_IT]后台回复【19cRPM包下载】即可获得。
https://www.oracle.com/database/technologies/oracle19c-linux-downloads.html
如果你的系统是Oracle Linux 平台,直接
yum -y installoracle-database-preinstall-19c
如果不是OracleLinux 平台,首先要下载对应平台的RPM,我这里用的是RedHat7.4,下载链接地址 https://oss.oracle.com/ol7/SRPMS-updates/ 搜索 -19c 即可找到,下载最新的即可。也可使用如下地址 https://yum.oracle.com/repo/OracleLinux/OL7/latest/x86_64/index.html
使用最新的即可,当然你也可以选择下载这里的 Oracle Linux 操作系统,注册Oracle 账号即可从如下网址下载软件。
https://edelivery.oracle.com/osdc/faces/SoftwareDelivery
检查基础环境配置
然后将软件包一起上传至服务器 /soft 目录。

如上使用 rpm 安装时需要很多依赖包,所以这里改用 yum 安装方式,首先配置 yum 源,我这里使用本地 yum 源的方式,将光盘传至本地 /media 目录下,新建配置 /etc/yum.repos.d/test.repo 文件如下,具体配置步骤就不用说了,前面有一篇文章专门介绍了可以点此查看[Linux 挂载光盘镜像配置本地 yum 源安装软件],大家可随意选择合适自己的安装方式即可。
第一步:preinstall 包安装

安装 19c 数据库软件
然后直接使用 yum 命令安装 19c 数据库软件
第二步:database 软件安装

如上信息,执行完脚本 Oracle home 配置安装完成,发现 oracle 用户也创建成功了, 然后便使用 /etc/init.d/oracledb_ORCLCDB-19c 文件可以配置一个模板数据库。那么我们看一下这个文件内容都有啥?
首先看到提示 RedHat or SuSE 需要配置 /etc/sysconfig/oracledb_ORCLCDB-19c,继续看一下这个文件内容呢?
[root@localhost opt]# more/etc/sysconfig/oracledb_ORCLCDB-19c.conf
#This is a configuration file to setup theOracle Database.
#It is used when running'/etc/init.d/oracledb_ORCLCDB configure'.
#Please use this file to modify the defaultlistener port and the
#Oracle data location.
# LISTENER_PORT: Database listener
LISTENER_PORT=1521
# ORACLE_DATA_LOCATION: Database oradatalocation
ORACLE_DATA_LOCATION=/opt/oracle/oradata
# EM_EXPRESS_PORT: Oracle EM Expresslistener
EM_EXPRESS_PORT=5500
可以看到这个文件就是配置监听端口、EM 端口号以及数据文件位置,默认为 /opt/oracle/oradata可按照自己机器实际情况修改,我这里将其修改为 /u01/app/oracle/oradata,然后建立目录赋权,如果上图中的实例名、数据库名均不需要改动的话,直接按照提示使用root 运行以下命令
/etc/init.d/oracledb_ORCLCDB-19c configure
配置实例即可,约 10 分钟左右即可完成。

我这里在折腾一下修改数据库名和实例名试试,简单的将其 CDB 名修改为 JiekeCDB, PDB 名字修改为 JiekePDB,其他不做改变,如下所示:
[root@localhost soft]# cp /etc/init.d/oracledb_ORCLCDB-19cdb_ORCLCDB-19c_bak
[root@localhost init.d]# ll oracle*
-rwx------ 1 root root 1281 Mar 12 02:22oracle-database-preinstall-19c-firstboot

[root@localhostinit.d]# mv /etc/init.d/oracledb_ORCLCDB-19c /etc/init.d/oracledb_JiekeCDB-19c
[root@localhostinit.d]# vi /etc/init.d/oracledb_JiekeCDB-19c
配置数据库
注意:这里修改了 SID 导致找不到 /etc/sysconfig/下的配置文件,那么需要修改或配置对应的文件名 oracledb_JiekeCDB-19c.conf。然后配置数据库,查看这个脚本文件 oracledb_JiekeCDB-19c 中间部分,其实就是静默创建实例,需要耐心等待10 分钟左右。
[root@localhost init.d]#/etc/init.d/oracledb_JiekeCDB-19c configure
The Oracle Database is not configured.Unable to read the configuration file'/etc/sysconfig/oracledb_JiekeCDB-19c.conf'

使用 oracle 用户登陆数据库,需要简单配置环境变量!

其他应用及配置可参考以前一篇 12c 相关的文章[Oracle 12CR2 安装配置与基础学习],这里就不多说了,怎么样?RPM 包安装还是很方便吧,不用图形化、配置监听等,简单多了,和19c 倡导自治数据库不谋而和,基本上实现了一键安装.
