Kafka单节点部署

1. 配置JAVA环境变量

   $ tar xf jdk-8u202-linux-x64.tar.gz
   $ mv jdk1.8.0_202 /usr/local/java
   $ vim /etc/profile
   export JAVA_HOME=/usr/local/java
   export JRE_HOME=JAVA_HOME/jre export CLASSPATH=.:JAVA_HOME/lib/dt.jar:JAVA_HOME/lib/tools.jar:JRE_HOME/lib
   export PATH=JAVA_HOME/bin:PATH
   $ source /etc/profile

2. 解压kafka安装包

   $ wget https://downloads.apache.org/kafka/3.4.1/kafka_2.13-3.4.1.tgz
   $ tar xf kafka_2.13-3.4.1.tgz
   $ mv kafka_2.13-3.4.1 /data/kafka

3. 修改zk配置

   $ vim /data/kafka/config/zookeeper.properties
   dataDir=/data/kafka/zookeeper
   clientPort=2181
   maxClientCnxns=0
   admin.enableServer=false

4. 修改kafka配置

   $ vim /data/kafka/config/server.properties
   broker.id=0
   listeners=PLAINTEXT://192.168.0.218:9092
   log.dirs=/data/kafka/kafka-logs
   zookeeper.connect=192.168.0.218:2181

5. zk托管到systemd

   $ vim /usr/lib/systemd/system/zookeeper.service
   [Unit]
   Description=Apache Zookeeper service
   Requires=network.target
   After=network.target

   [Service]
   Type=forking
   Environment=JAVA_HOME=/usr/local/java
   ExecStart=/data/kafka/bin/zookeeper-server-start.sh -daemon /data/kafka/config/zookeeper.properties
   ExecStop=/data/kafka/bin/zookeeper-server-stop.sh
   Restart=on-failure
   RestartSec=10s

   [Install]
   WantedBy=multi-user.target

6. kafka托管到systemd

   $ vim /usr/lib/systemd/system/kafka.service
   [Unit]
   Description=Apache Kafka server
   Documentation=http://kafka.apache.org/documentation.html
   Requires=network.target remote-fs.target
   After=network.target remote-fs.target zookeeper.service

   [Service]
   Type=forking
   Environment=JAVA_HOME=/usr/local/java
   ExecStart=/data/kafka/bin/kafka-server-start.sh -daemon /data/kafka/config/server.properties
   ExecStop=/data/kafka/bin/kafka-server-stop.sh
   Restart=on-failure
   RestartSec=10s

   [Install]
   WantedBy=multi-user.target

7. 重载systemd配置并启动服务

   $ systemctl daemon-reload
   $ systemctl start zookeeper
   $ systemctl start kafka
