阿里云 ECS 快速安装Oracle 19c

阿里云9折折扣码

操作系统使用 CentOS 7.6 64位，目前对于oracle没有任何必要使用32位操作系统了！！

磁盘在40GB系统盘的基础上增加一块ESSD云盘大小40GB，作为存放oracle数据库的基础配置。并启用每日自动备份！

网络设置使用默认配置，用户实际使用时：

若应用服务器位于阿里云同机房，一般可以直接使用内网连接，不需要太大的公网带宽
若应用服务器不在阿里云同机房，需要使用公网连接，则需要提高公网带宽

无需启动3389端口

安全组使用默认配置，后续需要为ORACLE监听配置安全组网络端口。

最终配置报价时317元/每月！

最后确认订单，服务器就绪后，ssh远程登陆。

首先划分磁盘并测试ESSD的IO, 第一块ESSD的路径一般为 /dev/vdb，在vdb上划分1个分区，并创建XFS文件系统，挂在到 /d01目录下

fdisk /dev/vdb



Welcome to fdisk (util-linux 2.23.2).

Changes will remain in memory only, until you decide to write them.
Be careful before using the write command.

测试一下ESSD的IO :

yum install fio


cd /d01

可以看到单块阿里云ESSD的随机读写 IOPS ,read: IOPS=2847 write: IOPS=951 还是不错的。

开始安装oracle 19c , 首先上传介质到服务器/root目录

使用浏览器下载以下2个介质并上传到服务器目录

https://download.oracle.com/otn/linux/oracle19c/190000/oracle-database-ee-19c-1.0-1.x86_64.rpm
https://yum.oracle.com/repo/OracleLinux/OL7/latest/x86_64/getPackage/oracle-database-preinstall-19c-1.0-1.el7.x86_64.rpm


su - root 
yum -y install git 
git clone https://github.com/macleanliu/ora-easy-deploy
yum -y localinstall oracle-database-preinstall-19c-1.0-1.el7.x86_64.rpm
rpm -ivh oracle-database-ee-19c-1.0-1.x86_64.rpm
bash ora-easy-deploy/create_db.sh

bash ora-easy-deploy/create_db.sh ，执行该脚本输入数据库名，数据库目录和SYS/SYSTEM密码等，后自动建库。

安装完成后,执行：

#设置ORACLE OS账户密码
su - root
passwd oracle                     
su - oracle

完成配置。

以上完成了基础配置，但外网客户端还是无法访问oracle服务器监听的，例如使用tnsping工具ping服务器监听，或sqlplus均无法登陆

ERROR:

我们在阿里云控制台，点选ECS服务器，更多=》网络和安全组=》安全组配置=》配置规则

点击添加安全组规则：

选择协议类型，ORACLE 1521 ，如果你要使用非默认ORACLE端口，即不使用1521端口，那么需要在端口范围内自行选择端口；这里我们使用默认端口，因为可以指定默认端口允许的外网IP，所以一般使用默认端口即可；授权对象中输入应用服务器的外网IP 。

点击确定后1分钟后，可以尝试登陆：
