云服务器初始化Kafka

本地机器（Git Bash（新版Windows10也可以直接使用命令））

scp ./jdk-8u91-linux-x64.tar.gz root@公网IP:/root
scp ./kafka_2.12-2.2.0.tgz root@公网IP:/root

云服务器登录后

tar zxvf jdk-8u91-linux-x64.tar.gz
mv jdk1.8.0_91 /opt/java

JAVA_HOME=/opt/java
PATH=$PATH:$JAVA_HOME/bin
export JAVA_HOME PATH 

java -version

tar zxvf kafka_2.12-2.2.0.tgz
cd kafka_2.12-2.2.0
vi config/server.properties

将listeners=PLAINTEXT://:9092注释去掉

将advertised.listeners=PLAINTEXT://your.host.name:9092注释去掉，your.host.name改成公网IP
