golang的kafka 框架有不少种, sarama是一种比较经常使用的,是用golang写的,可是不能支持consumer group。
confluent是一种,是调用c语言的库librdkafka,能够支持consumer group。可是会麻烦一点,须要安装librdkafka。html
先看官网上的一句话。
This client for Go depends on librdkafka v1.1.0 or later
用yum install安装的版本是不适合要求的。golang
For Redhat based distros, install librdkafka-devel using Confluent’s YUM repository.
对于CentOS须要先安装Confluent的yum源。
具体方法:
https://docs.confluent.io/current/installation/installing_cp/rhel-centos.htmlweb
Navigate to /etc/yum.repos.d/ and create a file named confluent.repo with these contents. This adds the Confluent repository.centos
[Confluent.dist] name=Confluent repository (dist) baseurl=https://packages.confluent.io/rpm/5.3/7 gpgcheck=1 gpgkey=https://packages.confluent.io/rpm/5.3/archive.key enabled=1 [Confluent] name=Confluent repository baseurl=https://packages.confluent.io/rpm/5.3 gpgcheck=1 gpgkey=https://packages.confluent.io/rpm/5.3/archive.key enabled=1
而后
yum install pkg-config
yum install librdkafka-devel框架
在golang中导入
