1、安装jdk
[root@linux-host1 ~]# tail /etc/profile
export JAVA_HOME=/usr/local/jdk1.8.0_161
export PATH=$JAVA_HOME/bin:$PATH
[root@linux-host1 ~]# source /etc/profile
[root@linux-host1 ~]# which java
/usr/local/jdk1.8.0_161/bin/java
[root@linux-host1 ~]# java -version
2、安装zookeeper
[root@linux-host1 ~]# cd /opt/zookeeper-3.4.14/
[root@linux-host1 zookeeper-3.4.14]# ./bin/zkServer.sh start
[root@linux-host1 ~]# netstat -lnpt
Proto Recv-Q Send-Q Local Address Foreign Address State PID/Program name
tcp 0 0 0.0.0.0:22 0.0.0.0:* LISTEN 939/sshd
tcp6 0 0 :::43727 :::* LISTEN 5399/java
tcp6 0 0 :::80 :::* LISTEN 940/httpd
tcp6 0 0 :::22 :::* LISTEN 939/sshd
tcp6 0 0 :::2181 :::* LISTEN 5399/java
配置systemd启动服务，
[root@linux-host1 ~]# vim /usr/lib/systemd/system/zookeeper.service
[Unit]
Description=zookeeper service
After=network.target
[Service]
Type=forking
Environment="PATH=/usr/local/jdk1.8.0_161/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/root/bin"
User=root
Group=root
ExecStart=/opt/zookeeper-3.4.14/bin/zkServer.sh start
ExecStop=/opt/zookeeper-3.4.14/bin/zkServer.sh stop
Restart=on-failure
[Install]
WantedBy=multi-user.target
[root@linux-host1 ~]# systemctl daemon-reload
[root@linux-host1 ~]# systemctl stop zookeeper
[root@linux-host1 ~]# systemctl status zookeeper
3、安装kafka
Kafka解压目录：/root/ansibles/kafka/kafka_2.12-1.0.0
[root@linux-host1 ~]# vim /lib/systemd/system/kafka.service
[Unit]
Description=Apache Kafka server (broker)
After=network.target
[Service]
Type=forking
Environment="PATH=/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/local/jdk1.8.0_161/bin"
User=root
Group=root
ExecStart=/opt/kafka_2.12-1.0.0/bin/kafka-server-start.sh -daemon /opt/kafka_2.12-1.0.0/config/server.properties
ExecStop=/opt/kafka_2.12-1.0.0/bin/kafka-server-stop.sh
[Install]
WantedBy=multi-user.target
[root@linux-host1 ~]# systemctl daemon-reload
[root@linux-host1 ~]# systemctl status kafka
[root@linux-host1 ~]# systemctl start kafka
相关服务端口，
完成kafka安装部署。
