1、安装Oracle数据库

1.安装 Oracle 预安装 RPM

yum -y localinstall https://yum.oracle.com/repo/OracleLinux/OL7/latest/x86_64/getPackage/oracle-database-preinstall-18c-1.0-1.el7.x86_64.rpm

2.安装 Oracle Database RPM

https://www.oracle.com/technetwork/database/enterprise-edition/downloads/index.html数据库

# 若未注册可用个人，勿作修改

yum -y localinstall /tmp/oracle-database-ee-18c-1.0-1.x86_64.rpm

 

2、建立和配置 Oracle 数据库

1.查看配置

# 根据须要修改 cat /etc/sysconfig/oracledb_ORCLCDB-18c.conf #This is a configuration file to setup the Oracle Database. #It is used when running '/etc/init.d/oracledb_ORCLCDB configure'. #Please use this file to modify the default listener port and the #Oracle data location. # LISTENER_PORT: Database listener # 侦听器的侦听端口 LISTENER_PORT=1521 # ORACLE_DATA_LOCATION: Database oradata location # 数据存放位置 ORACLE_DATA_LOCATION=/opt/oracle/oradata # EM_EXPRESS_PORT: Oracle EM Express listener # Enterprise Manager 的侦听端口 EM_EXPRESS_PORT=5500

2.建立 Oracle 数据库实例

查看脚本express

执行脚本vim

# 执行脚本以后将建立一个容器数据库(ORCLCDB)和一个可插拔数据库(ORCLPDB1)，而且配置的默认监听端口是1521。注意 /opt 目录剩余空间大小 /etc/init.d/oracledb_ORCLCDB-18c configure

查看 oratabbash

# 记录每一个数据库的信息，最后一个字母为是否在系统启动时启动 cat /etc/oratab

 

3、使用

# 做用与 /etc/profile 同样 vim /etc/profile.d/oracle.sh export ORACLE_BASE=/opt/oracle/oradata export ORACLE_HOME=/opt/oracle/product/18c/dbhome_1 export PATH=$ORACLE_HOME/bin:$PATH export ORACLE_SID=ORCLCDB export NLS_LANG=american_america.AL32UTF8 # 刷新环境变量 source /etc/profile.d/oracle.sh

 

相关命令oracle

# 监听端口查看 netstat -nultp  | grep -E '1521|5500' # 监听 lsnrctl start lsnrctl stop lsnrctl stat # 数据库 dbstart $ORACLE_HOME dbshut $ORACLE_HOME

 

链接到 oracle 数据库app

# 切换到 oracle 用户，root 用户下没法链接 su - oracle # 启动监听 lsnrctl start # 以 sysdba 身份登陆 sqlplus / as sysdba

修改数据库密码tcp

-- 启动数据库
startup; -- 配置 system 和 sys 帐户的密码
alter user system identified by oracle; alter user sys identified by oracle; -- 版本查询
select banner from sys.v_$version; -- 查看全部用户
select username from dba_users;

 

查看 em 界面，Oracle 18c 默认会开启 Enterprise Manager Database Express，修改完sys密码以后，就能够访问：https://IP:5500/em，忽略 https 证书错误，容许 Flash 加载ide

 

远程链接至 Oracle 数据库 (Navicat Premium)

 

4、添加开机自启动

1.新建环境参数

vim /etc/sysconfig/ORCLCDB.oracledb ORACLE_BASE=/opt/oracle/oradata ORACLE_HOME=/opt/oracle/product/18c/dbhome_1 ORACLE_SID=ORCLCDB

2.新建监听服务

vim /usr/lib/systemd/system/ORCLCDB@lsnrctl.service [Unit] Description=Oracle Net Listener After=network.target [Service] Type=forking EnvironmentFile=/etc/sysconfig/ORCLCDB.oracledb ExecStart=/opt/oracle/product/18c/dbhome_1/bin/lsnrctl start ExecStop=/opt/oracle/product/18c/dbhome_1/bin/lsnrctl stop User=oracle [Install] WantedBy=multi-user.target

3.新建数据库服务

vim /usr/lib/systemd/system/ORCLCDB@oracledb.service [Unit] Description=Oracle Database service After=network.target lsnrctl.service [Service] Type=forking EnvironmentFile=/etc/sysconfig/ORCLCDB.oracledb ExecStart=/opt/oracle/product/18c/dbhome_1/bin/dbstart $ORACLE_HOME ExecStop=/opt/oracle/product/18c/dbhome_1/bin/dbshut $ORACLE_HOME User=oracle [Install] WantedBy=multi-user.target

4.设置服务自启动

# 刷新服务 systemctl daemon-reload # 设置开机自启动 systemctl enable ORCLCDB@lsnrctl ORCLCDB@oracledb

5.设置数据库自启动

# 此文件由 root.sh 建立 # 格式为：$ORACLE_SID:$ORACLE_HOME:<N|Y> # 第一个和第二个字段分别是数据库的系统标识符和主目录。 第三个字段为是否跟随 dbstart 命令启动数据库实例 # 不容许有相同 $ORACLE_SID 的条目 vim /etc/oratab ORCLCDB:/opt/oracle/product/18c/dbhome_1:Y
