我正在尝试将Apache Kafka设置为在同一网络上运行CentOS的两个虚拟机之间进行通信。我最初在一台机器上设置了Kafka生产者和消费者，并且一切运行顺利。然后，我在另一台计算机上设置了Kafka，并在尝试使其连接的过程中，出现错误“ bootstrap-server未被识别的选项”（我运行的是Kafka的最新版本2.2）。
这是我用来尝试建立生产者连接的方式：
bin/kafka-console-producer.sh --bootstrap-server 10.0.0.11:9092 --topic test
在消费者方面：
bin/kafka-console-producer.sh --bootstrap-server 10.0.0.11:9092 --topic test
10.0.0.11计算机正在运行服务器本身。

根据Apache Kafka文档（可在https://kafka.apache.org/documentation/#quickstart_send中找到），应使用#include <iostream>
#include <string>
#include <boost/algorithm/string.hpp>
using namespace std;
int main() {
string mRNA, acids;
int hold[3];
cout<<"Enter mRNA strand. (Ex. AUG CCA UUG)\n";
getline(cin, mRNA);
boost::erase_all(mRNA, " ");
cout<<mRNA<<endl<<"length: "<<mRNA.length()<<endl;
int codonNum = (mRNA.length() - (mRNA.length() % 3)) / 3;
cout<<codonNum<<" codons\n";
string codon[4][4][4] = {
{ {"Phe ", "Phe ", "Leu ", "Leu "}, {"Ser ", "Ser ", "Ser ", "Ser "}, {"Tyr ", "Tyr ", "STOP ", "STOP "}, {"Cys ", "Cys ", "STOP ", "Trp "} },
{ {"Leu ", "Leu ", "Leu ", "Leu "}, {"Pro ", "Pro ", "Pro ", "Pro "}, {"His ", "His ", "Gin ", "Gin "}, {"Arg ", "Arg ", "Arg ", "Arg "} },
{ {"Ile ", "Ile ", "Ile ", "Met "}, {"Thr ", "Thr ", "Thr ", "Thr "}, {"Asn ", "Asn ", "Lys ", "Lys "}, {"Ser ", "Ser ", "Arg ", "Arg "} },
{ {"Val ", "Val ", "Val ", "Val "}, {"Ala ", "Ala ", "Ala ", "Ala "}, {"Asp ", "Asp ", "Glu ", "Glu "}, {"Gly ", "Gly ", "Gly ", "Gly "} }
};
for (int x = 1; x <= (mRNA.length() - (mRNA.length() % 3)); x =+ 3){
for (int y = 0; y <= 2; y++){
switch (mRNA[x+y]){
case 'U': hold[y] = 0;
break;
case 'C': hold[y] = 1;
break;
case 'A': hold[y] = 2;
break;
case 'G': hold[y] = 3;
break;
case 'u': hold[y] = 0;
break;
case 'c': hold[y] = 1;
break;
case 'a': hold[y] = 2;
break;
case 'g': hold[y] = 3;
break;
}
acids += codon[hold[0]][hold[1]][hold[2]];
}
}
cout<<"Sequence: "<<acids;
/* for (int x = 0; x <= 3; x++) {
for (int y = 0; y <= 3; y++) {
for (int z = 0; z <= 3; z++) {
cout<<codon[x][y][z];
}
cout<<endl;
}
cout<<endl;
} */
return 0;

属性传递代理地址。
命令将是：
--broker-list
答案 1 :(得分：1)
以下命令应该起作用。
./bin/kafka-topics.sh --create --zookeeper localhost:2181 --replication-factor 1 --partitions 1 --topic test
答案 2 :(得分：1)
./ kafka-console-consumer.sh --zookeeper localhost：2181 --topic fred
仅使此命令有效。但是，在即将发布的主要版本中，必须使用bootstrap-server选项。
当我使用上述命令时，它会发出警告：“不建议将ConsoleConsumer与旧使用者一起使用，并且在将来的主要版本中将删除它。考虑通过传递[bootstrap-server]而不是[zookeeper]使用新使用者。”
