依赖插件安装

[root@svn ~]# yum -y install binutils-* compat-libstdc* elfutils-libelf* elfutils-libelf-devel* 
[root@svn ~]# yum -y install gcc-* glibc* glibc-common* glibc-devel* glibc-headers* ksh* libaio-* 
[root@svn ~]# yum -y install libaio-devel* libgcc*  libstdc++*  libstdc++-devel* make* sysstat* unixODBC*

 准备Oracle rpm包

 1.下载安装包 oracle-database-ee-19c-1.0-1.x86_64.rpm
官网下载：
https://www.oracle.com/database/technologies/

没有Oracle账号的，烦请注册一个，保证收到邮件即可，其他的信息随便填
下载好的rpm包上传到linux服务器，文件比较大，需要等待一段时间

2.下载预安装包 oracle-database-preinstall-19c-1.0-1.el7.x86_64.rpm
官网下载：http://yum.oracle.com/repo/OracleLinux/OL7/latest/x86_64/getPackage/oracle-database-preinstall-19c-1.0-1.el7.x86_64.rpm

[root@svn ~]# wget http://yum.oracle.com/repo/OracleLinux/OL7/latest/x86_64/getPackage/oracle-database-preinstall-19c-1.0-1.el7.x86_64.rpm

安装oracle

#前提：要把这两个rpm包上传到Linux服务器

[root@svn ~]# yum -y localinstall oracle-database-preinstall-19c-1.0-1.el7.x86_64.rpm
[root@svn ~]# yum -y localinstall oracle-database-ee-19c-1.0-1.x86_64.rpm

#到此orcle安装成功

创建用户，配置环境变量

[root@svn ~]# groupadd dba

[root@svn ~]# groupadd oinstall  

[root@svn ~]# useradd -g oinstall  -G dba oracle

[root@svn ~]# su - oracle
执行命令 vim .bash_profile，在该文档里面追加以下内容：

export ORACLE_HOME=/opt/oracle/product/19c/dbhome_1
export PATH=$PATH:/opt/oracle/product/19c/dbhome_1/bin
export ORACLE_SID=ORCLCDB
stty erase ^h
export NLS_LANG="AMERICAN_AMERICA.UTF8"

[oracle@svn ~]$ source .bash_profile

登入数据库

[root@svn ~]# su - oracle

[oracle@svn ~]$ sqlplus / as sysdba

SQL> alter user system identified by 123456;

重启oracle数据库

SQL> shutdown immediate            #立即关闭数据库服务
SQL> startup                                 #开启数据库服务

oracle意外挂掉，重启oracle 步骤

[root@svn ~]# su - oracle

[oracle@svn ~]$ lsnrctl status

停止数据库的监听器

[oracle@svn ~]$ lsnrctl stop

进入数据库

[oracle@svn ~]$ sqlplus / as sysdba

SQL> shutdown immediate

开启数据库的监听器

[oracle@svn ~]$ lsnrctl start

查看数据库的监听器情况：

[oracle@svn ~]$ lsnrctl status
