上传到服务器/opt目录

安装

# kafka安装目录为 /opt/kafka
cd /opt;
mkdir kafka;
mv kafka_2.13-2.7.0.tgz ./kafka;cd kafka;
#解压
tar -zxvf kafka_2.13-2.7.0.tgz;
cd kafka_2.13-2.7.0;

启动内置zookeeper

cd /opt/kafka/kafka_2.13-2.7.0;
#注意启动方式为前台启动 窗口不能关闭
./bin/zookeeper-server-start.sh config/zookeeper.properties;# 后台运行启动方式为
./bin/zookeeper-server-start.sh -daemon config/zookeeper.properties#关闭zookeeper
bin/zookeeper-server-stop.sh

启动kafka server

cd /opt/kafka/kafka_2.13-2.7.0;
#前端启动方式为
./bin/kafka-server-start.sh config/server.properties;#后台启动方式为
./bin/kafka-server-start.sh -daemon config/server.properties#关闭kafka
bin/kafka-server-stop.sh

开放防火墙端口

firewall-cmd --add-port=9092/tcp --permanent;
firewall-cmd --reload;

设置自启动

设置kafka.service

vim /lib/systemd/system/kafka.service

内容为

[Unit]
Description=Apache Kafka server (broker)
Documentation=http://kafka.apache.org/documentation.html
Requires=network.target remote-fs.target
After=network.target remote-fs.target kafka-zookeeper.service[Service]
Type=simple
User=root
Group=root
Environment="JAVA_HOME=/opt/jdk1.8.0_201"
ExecStart=/opt/kafka/kafka_2.13-2.7.0/bin/kafka-server-start.sh /opt/kafka/kafka_2.13-2.7.0/config/server.properties
ExecStop=/opt/kafka/kafka_2.13-2.7.0/bin/kafka-server-stop.sh
Restart=on-abnormal[Install]
WantedBy=multi-user.target

上面的 kafka-zookeeper.service 是后面要创建的 zookeeper 服务的名称

Environment 为 java 的安装位置，需要修改成自己的位置

ExecStart 为启动命令，可以直接复制上面测试的时候的启动命令

ExecStop 为停止命令，也可以直接复制上面的

其他就不需要做修改

设置kafka-zookeeper.service

vim /lib/systemd/system/kafka-zookeeper.service

内容为

[Unit]
Description=Apache Kafka Zookeeper server
Documentation=http://zookeeper.apache.org
Requires=network.target remote-fs.target
After=network.target remote-fs.target[Service]
Type=simple
User=root
Group=root
Environment="JAVA_HOME=/opt/jdk1.8.0_201"
ExecStart=/opt/kafka/kafka_2.13-2.7.0/bin/zookeeper-server-start.sh /opt/kafka/kafka_2.13-2.7.0/config/zookeeper.properties
ExecStop=/opt/kafka/kafka_2.13-2.7.0/bin/zookeeper-server-stop.sh
Restart=on-abnormal[Install]
WantedBy=multi-user.target

跟上面的 kafka 配置一样，将启动命令和停止命令的路径修改成自己的即可

设置开机启动

systemctl daemon-reloadsystemctl enable kafka-zookeeper
systemctl start kafka-zookeeper
systemctl stop kafka-zookeepersystemctl enable kafka
systemctl start kafka
systemctl stop kafka
