在centos7下配置zookeeper開機啟動kafka開機啟動-查看kafka版本信息-版本升級

vi /usr/lib/systemd/system/zookeeper.service

[Unit]
Description=zookeeper
After=network.target remote-fs.target nss-lookup.target

[Service]
Type=forking
Environment=JAVA_HOME=/usr/local/jdk1.8.0_211 #注意沒有這個環境變量服務可能無法啟動
ExecStart=/opt/zookeeper/zookeeper-3.4.10/bin/zkServer.sh start
ExecStop=/opt/zookeeper/zookeeper-3.4.10/bin/zkServer.sh stop
PIDFile=/opt/zookeeper/zkdata/zookeeper_server.pid
PrivateTmp=true
[Install]
WantedBy=multi-user.target

 

systemctl daemon-reload
systemctl restart zookeeper
systemctl status zookeeper

systemctl enable zookeeper

kafka開機啟動

vi /opt/kafka/kafkastart.sh #kafka啟動腳本

#!/bin/bash
nohup /opt/kafka/kafka_2.11-1.1.0/bin/kafka-server-start.sh /opt/kafka/kafka_2.11-1.1.0/config/server.properties >/dev/null 2>&1 &

vi /opt/kafka/kafkastop.sh #kafka停止腳本

#!/bin/bash
pid=`ps -ef|grep kafka | grep -v 'grep' | awk '{print $2}'`
kill -9 $pid

vi /usr/lib/systemd/system/kafka.service 開機啟動腳本

[Unit]
Description=kafka  # 這個名字就可以 systemctl restart kafka啟動了
After=network.target remote-fs.target nss-lookup.target zookeeper.service

[Service]
Type=forking
Environment=JAVA_HOME=/usr/local/jdk1.8.0_211 #注意沒有這個環境變量服務可能無法啟動
ExecStart=/opt/kafka/kafkastart.sh
ExecStop=/opt/kafka/kafkastop.sh
PrivateTmp=true
[Install]
WantedBy=multi-user.target

chmod 700 /opt/kafka/kafkastop.sh
chmod 700 /opt/kafka/kafkastart.sh

systemctl daemon-reload
systemctl restart kafka
systemctl status kafka

systemctl enable kafka

 注意

kafka是在zookeeper啟動以后才能正常啟動 所以上面配置需要在zookeeper.service后啟動

After=network.target remote-fs.target nss-lookup.target zookeeper.service

find ./libs/ -name \*kafka_\* | head -1 | grep -o '\kafka[^\n]*' #在kafka目錄版本查看

 版本升級

cp /opt/kafka/kafka_2.11-1.1.0/config/server.properties /opt/kafka/kafka_2.12-2.3.1/config/server.properties
nohup /opt/kafka/kafka_2.12-2.3.1/bin/kafka-server-start.sh /opt/kafka/kafka_2.12-2.3.1/config/server.properties >/dev/null 2>&1 &
192.168.130.36:9092-版本kafka_2.12-2.3.1
