1.安装JDK

目前官网不能直接下载,在网上找到1.8.0版本安装包下载到本地。

1.1.下载jdk并解压

[root@iz2zei2y693gtrgwlibzlwz java]# ls
jdk1.8.0_191  jdk-8u191-linux-x64.tar.gz

1.2.配置java环境变量

在文件中/etc/profile追加配置:

export JAVA_HOME=/usr/local/java/jdk1.8.0_191
export CLASSPATH=.:$JAVA_HOME/jre/lib/rt.jar:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar
export PATH=$PATH:$JAVA_HOME/bin

使配置生效

[root@iz2zei2y693gtrgwlibzlwz java]# source /etc/profile

1.3.验证jdk是否安装成功

[root@iz2zei2y693gtrgwlibzlwz java]# java -version
java version "1.8.0_191"
Java(TM) SE Runtime Environment (build 1.8.0_191-b12)
Java HotSpot(TM) 64-Bit Server VM (build 25.191-b12, mixed mode)

2.安装zookeeper

2.1.下载

http://zookeeper.apache.org/releases.html

2.2.解压

tar –zxvf zookeeper-3.4.10.tar.gz

2.3.复制conf目录下的zoo_sample.cfg,并命名为zoo.cfg

2.4.修改zoo.cfg配置文件

# The number of milliseconds of each tick
tickTime=2000
# The number of ticks that the initial 
# synchronization phase can take
initLimit=10
# The number of ticks that can pass between 
# sending a request and getting an acknowledgement
syncLimit=5
# the directory where the snapshot is stored.
# do not use /tmp for storage, /tmp here is just 
# example sakes.

dataDir=/usr/local/zookeeper/zookeeper-3.4.10/data

dataLogDir=/usr/local/zookeeper/zookeeper-3.4.10/logs

# the port at which the clients will connect
clientPort=2181
# the maximum number of client connections.
# increase this if you need to handle more clients
#maxClientCnxns=60
#
# Be sure to read the maintenance section of the 
# administrator guide before turning on autopurge.
#
http://zookeeper.apache.org/doc/current/zookeeperAdmin.html#sc_maintenance
#
# The number of snapshots to retain in dataDir
#autopurge.snapRetainCount=3
# Purge task interval in hours
# Set to “0” to disable auto purge feature
#autopurge.purgeInterval=1

#2888,3888 are election port
server.1=39.**.**.**:2888:3888   #改成自己ip

其中,2888端口号是服务之间通信的端口,而3888是;zookeeper与其他应用程序通信的端口.

2.5.创建myid文件

创建dataDir参数指定的目录(这里指的是“/usr/local/zookeeper/zookeeper-3.4.10/data”),并在目录下创建文件,命名为“myid”。

2.6.编辑myid文件

在对应的IP的机器上输入对应的编号。如在zookeeper上,“myid”文件内容就是1。由于本次只在单点上进行安装配置,所以只有一个server.1。若还有其他服务器,比如地址为192.168.1.102,则在zoo.cfg文件中还需加入server.2=192.168.1.102:2888:3888。那么myid文件在192.168.1.102服务器上的内容就是2。至此,如果是多服务器配置,就需要将zookeeper-3.4.3目录拷贝到其他服务器,然后按照上述的方法修改myid。

2.7.在/etc/profile文件设置PATH

在profile文件尾追加:

export PATH=$PATH:/usr/local/zookeeper/zookeeper-3.4.10/bin

安装完毕!

2.8.启动

zkServer.sh start

输入jps命令查看进程

1573 QuorumPeerMain
1654 Jps

其中,QuorumPeerMain是zookeeper进程,启动正常。

查看状态:zkServer.sh status

-
JMX enabled by default
Using config: /usr/local/zookeeper-3.4.6/bin/../conf/zoo.cfg
Mode: standalone

启动客户端脚本:zkCli.sh -server ip:2181

停止zookeeper进程:zkServer.sh stop

3.安装kafka

下载地址:https://mirrors.cnnic.cn/apache/kafka 

3.1.下载kafka

wget https://mirrors.cnnic.cn/apache/kafka/2.1.0/kafka_2.11-2.1.0.tgz

解压

tar -zxvf kafka_2.12-1.1.0.tgz

 

3.2.配置kafka环境变量

在/etc/profile文件中追加配置:

export KAFKA_HOME=/usr/local/kafka/kafka_2.11-2.1.0
export PATH=$KAFKA_HOME/bin:$PATH

使配置生效

[root@iz2zei2y693gtrgwlibzlwz kafka]# source /etc/profile

3.3.验证kafka是否安装成功

[root@iz2zei2y693gtrgwlibzlwz kafka]#  echo $KAFKA_HOME
/usr/local/kafka/kafka_2.11-2.1.0

3.4.修改kafka配置文件中以下配置

broker.id=0
listeners=PLAINTEXT://:9092

advertised.listeners=PLAINTEXT://你的ip:9092

zookeeper.connect=localhost:2181

3.4.启动kafka服务

[root@iz2zei2y693gtrgwlibzlwz config]#  kafka-server-start.sh -daemon $KAFKA_HOME/config/server.properties
[root@iz2zei2y693gtrgwlibzlwz config]# jps
24177 QuorumPeerMain
899 Kafka
8506 Jps

3.4.关闭服务

先关闭kafka,在关闭zookeeper

 kafka-server-stop.sh
zookeeper-server-stop.sh

查看服务是否已关闭

[root@localhost ~]# jps
15462 Jps
