ORDS就是Oracle REST Data Services。
环境如下：
- Oracle Linux 8
- Oracle Database 19c
- IP地址为A.B.C.D
要安装最新版本的ORDS，当前为24.1.1。
全程参考文档：Installing and Configuring Oracle REST Data Services
安装ORDS
添加repository到yum配置中
## 如果是Linux 7
sudo yum-config-manager --add-repo=http://yum.oracle.com/repo/OracleLinux/OL7/oracle/software/x86_64
## 如果是Linux 8
sudo yum-config-manager --add-repo=https://yum.oracle.com/repo/OracleLinux/OL8/oracle/software/x86_64/
yum安装，速度很快，就115M：
$ yum info ords

安装尾部有重要的信息，给出了后续配置的命令和启动服务的命令：
INFO: Before starting ORDS service, run the below command as user oracle:

INFO: To enable the ORDS service during startup, run the below command:
sudo systemctl enable ords
配置ORDS
虽然我已经有Java 8，ORDS需要Java 11或以上才能运行。
$ ords --config /etc/ords/config install
Error: ORDS requires Java 11 and above to run.
Found Java version 1.8.0_341.
Please set JAVA_HOME to appropriate version and update PATH if necessary.
从官网下载JDK并安装：
$ sudo rpm -ivh jdk-11.0.23_linux-x64_bin.rpm
不小心下载了个低版本的，没关系，也能用。
配置其实就1个命令：
ords --config /etc/ords/config install
但这个命令实际在配置成功后，还会运行ORDS。所以这是个前台命令，不要傻傻的等他结束。看到下面的信息，就表示安装成功了。

看下上面那段话：
Oracle REST Data Services (ORDS) 是用于 Oracle 数据库的 HTTPS Web 网关。功能包括 SQL Developer Web、Oracle APEX 访问、用于数据和数据库的 REST API 以及 Oracle Database API for MongoDB 等。
SQL Developer Web就是SQL Developer的网页版。其实他最新的名称是Oracle Database Actions。后续我们再探索。
