阿里云
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 :

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:

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

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:

可以看到登陆成功,这样我们就可以愉快的使用阿里云上的 ORACLE 19c了!!
