本章介绍NIFI组件的使用。
主要有：Nginx反向代理NIFI，配置SSLContextService
Nginx反向代理NIFI
使用nginx反向代理NIFI配置如下
1 upstream nifi_server {
2 ip_hash;
3 server 127.0.0.1:18002;
4 }
5
6 server {
7 listen 80;
8 server_name nifi.example.com;
9 charset utf-8;
10
11 location / {
12 proxy_pass http://nifi_server;
13
14 proxy_set_header Host $host;
15 proxy_set_header X-Real-IP $remote_addr;
16 proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
17 proxy_set_header X-ProxyScheme http;
18 proxy_set_header X-ProxyHost nifi.example.com
19 proxy_set_header X-ProxyPort 80;
20 proxy_set_header X-ProxyContextPath /;
21 }
22 }
配置SSLContextService
SSLContextService，可以用来发送https请求
SSL Context Service实例配置信任库属性：
- Truststore文件名：Java安装中的cacerts文件
- 如果在您的系统上设置了$JAVA_HOME，它应该有助于指向正确的方向。如果不是，cacerts的位置根据环境而变化，但是对于它们各自的OS大致如下
- OS X： /Library/Java/JavaVirtualMachines/jdk<version>.jdk/Contents/Home/jre/lib/security/cacerts
- Windows：C:\Program Files\Java\jdk <version>\jre\lib\security\ cacerts
- Linux：/usr/local/java-<version>/jre/lib/security/cacerts
- 如果在您的系统上设置了$JAVA_HOME，它应该有助于指向正确的方向。如果不是，cacerts的位置根据环境而变化，但是对于它们各自的OS大致如下
- Truststore类型：JKS
- Truststore密码：如果您使用的是默认Java密钥库，则默认密码为"changeit"
