一. 环境配置

? 虚拟机安装建议分2G内存,30G硬盘。

  1. 关闭防火墙(或放行相关端口)

    systemctl stop firewalld
    systemctl disable firewalld
    
  2. 关闭selinux

    • 修改SELINUX=disabled

      vi /etc/selinux/config
      
      # This file controls the state of SELinux on the system.
      # SELINUX= can take one of these three values:
      #     enforcing - SELinux security policy is enforced.
      #     permissive - SELinux prints warnings instead of enforcing.
      #     disabled - No SELinux policy is loaded.
      SELINUX=disabled
      # SELINUXTYPE= can take one of three values:
      #     targeted - Targeted processes are protected,
      #     minimum - Modification of targeted policy. Only selected processes are protected.
      #     mls - Multi Level Security protection.
      SELINUXTYPE=targeted
      
    • 重启

      reboot
      
  3. oracle-database-ee-19c-1.0-1.x86_64.rpmoracle-database-preinstall-19c-1.0-1.el7.x86_64.rpm上传到/opt

二. 依赖安装

  1. 安装oracle-database-preinstall-19c-1.0-1.el7.x86_64.rpm

    yum -y localinstall /opt/oracle-database-preinstall-19c-1.0-1.el7.x86_64.rpm
    

    CentOS7 Oracle19c rpm安装

三. 安装配置Oracle 19c

  1. 安装Oracle 19c

    yum -y localinstall /opt/oracle-database-ee-19c-1.0-1.x86_64.rpm
    

    CentOS7 Oracle19c rpm安装

  2. 初始化Oracle数据库(时间较长)

    /etc/init.d/oracledb_ORCLCDB-19c configure
    

    CentOS7 Oracle19c rpm安装

  3. 配置环境变量

    • 却换到oracle用户

      su - oracle
      
    • 添加环境变量,在/home/oracle/.bash_profile中添加export ORACLE_HOME=/opt/oracle/product/19c/dbhome_1export PATH=$PATH:/opt/oracle/product/19c/dbhome_1/binexport ORACLE_SID=ORCLCDB

      vi /home/oracle/.bash_profile
      
      # .bash_profile
      
      # Get the aliases and functions
      if [ -f ~/.bashrc ]; then
              . ~/.bashrc
      fi
      
      # User specific environment and startup programs
      
      PATH=$PATH:$HOME/.local/bin:$HOME/bin
      
      export PATH
      
      export ORACLE_HOME=/opt/oracle/product/19c/dbhome_1
      export PATH=$PATH:/opt/oracle/product/19c/dbhome_1/bin
      export ORACLE_SID=ORCLCDB
      
    • 使环境变量生效

      source /home/oracle/.bash_profile
      
  4. 登陆数据库

    sqlplus / as sysdba
    

    CentOS7 Oracle19c rpm安装

  5. 修改system密码为123456

    alter user system identified by 123456;
    
  6. 退出数据库

    exit;
    

四. 设置数据库监听自启动

  1. 修改/etc/oratab文件NY

    vi /etc/oratab
    
    # This file is used by ORACLE utilities.  It is created by root.sh
    # and updated by either Database Configuration Assistant while creating
    # a database or ASM Configuration Assistant while creating ASM instance.
    
    # A colon, ‘:‘, is used as the field terminator.  A new line terminates
    # the entry.  Lines beginning with a pound sign, ‘#‘, are comments.
    #
    # Entries are of the form:
    #   $ORACLE_SID:$ORACLE_HOME:<N|Y>:
    #
    # The first and second fields are the system identifier and home
    # directory of the database respectively.  The third field indicates
    # to the dbstart utility that the database should , "Y", or should not,
    # "N", be brought up at system boot time.
    #
    # Multiple entries with the same $ORACLE_SID are not allowed.
    #
    #
    ORCLCDB:/opt/oracle/product/19c/dbhome_1:Y
    
  2. /etc/rc.local中添加su - oracle -c ‘lsnrctl start‘su - oracle -c ‘dbstart‘

    su root # 却换为root用户
    vi /etc/rc.local
    
    #!/bin/bash
    # THIS FILE IS ADDED FOR COMPATIBILITY PURPOSES
    #
    # It is highly advisable to create own systemd services or udev rules
    # to run scripts during boot instead of using this file.
    #
    # In contrast to previous versions due to parallel execution during boot
    # this script will NOT be run after all other services.
    #
    # Please note that you must run ‘chmod +x /etc/rc.d/rc.local‘ to ensure
    # that this script will be executed during boot.
    
    touch /var/lock/subsys/local
    
    su - oracle -c ‘lsnrctl start‘
    su - oracle -c ‘dbstart‘
    
  3. 修改$ORACLE_HOME/bin/dbstart文件,修改ORACLE_HOME_LISTNER=$ORACLE_HOME

    vi $ORACLE_HOME/bin/dbstart
    

    $ORACLE_HOME/bin/dbstart 文件局部

    ...
    #####################################
    
    LOGMSG="logger -puser.alert -s "
    
    trap ‘exit‘ 1 2 3
    
    # for script tracing
    case $ORACLE_TRACE in
      T) set -x ;;
    esac
    
    # Set path if path not set (if called from /etc/rc)
    SAVE_PATH=/bin:/usr/bin:/etc:${PATH} ; export PATH
    SAVE_LLP=$LD_LIBRARY_PATH
    
    # First argument is used to bring up Oracle Net Listener
    ORACLE_HOME_LISTNER=$ORACLE_HOME
    if [ ! $ORACLE_HOME_LISTNER ]; then
      echo "Since ORACLE_HOME is not set, cannot auto-start Oracle Net Listener."
      echo "Usage: $0 ORACLE_HOME"
    else
    ...
    
  4. 设置CentOS7,8开机执行/etc/rc.local文件(CentOS7,8开机不执行/etc/rc.local文件)

    • /etc/rc.d/rc.local 添加 可执行权限

      chmod a+x /etc/rc.d/rc.local 
      
    • 将 rc-local 服务设置成开机启动(默认状态是 static,会被其他service服务调用执行。不过还是修改一下,以防那个服务被停用就牵连了)

      systemctl enable rc-local
      
    • 重启,用sqldeveloper链接,验证是否成功

      reboot
      

      CentOS7 Oracle19c rpm安装

    • 删除/optoracle-database-ee-19c-1.0-1.x86_64.rpmoracle-database-preinstall-19c-1.0-1.el7.x86_64.rpm

      rm /opt/oracle-database-ee-19c-1.0-1.x86_64.rpm /opt/oracle-database-preinstall-19c-1.0-1.el7.x86_64.rpm
