linux安装zookeeper和kafka_setting -d jdk.tls.rejectclientinitiatedrenegotiat

        安装zookeeper和kafka之前，先检查是否安装java。如果没有，可以在如下链接中下载对应版本的jdk。

Java Downloads | Oracle

一、安装java

        我这里下载的是jdk-8u271-linux-x64.tar.gz，操作如下：

[root@lucas src]# ll | grep jdk
-rw-r--r--  1 root root 143142634 Dec 30 10:23 jdk-8u271-linux-x64.tar.gz
[root@lucas src]# tar -zxvf jdk-8u271-linux-x64.tar.gz
...
[root@lucas src]# ll | grep jdk
drwxr-xr-x  8 root  root      4096 Sep 17 01:14 jdk1.8.0_271
-rw-r--r--  1 root  root  143142634 Dec 30 10:23 jdk-8u271-linux-x64.tar.gz
 
[root@lucas src]# mv jdk1.8.0_271 /usr/local/java
[root@lucas src]# cd /usr/local/
[root@lucas local]# ll | grep java
drwxr-xr-x  8 root   root     4096 Sep 17 01:14 java

        经过以上操作，java已经装好，下面就是在/etc/bashrc设置环境变量：

export JAVA_HOME=/usr/local/java
export PATH=$PATH:$JAVA_HOME/bin

        保存退出后，执行以下命令即可。

source /etc/bashrc

        此时可查看java版本：

[root@lucas local]# java -version
java version "1.8.0_271"
Java(TM) SE Runtime Environment (build 1.8.0_271-b09)
Java HotSpot(TM) 64-Bit Server VM (build 25.271-b09, mixed mode)

二、安装zookeeper

        zookeeper可从该页面下载：Apache ZooKeeper

       这里下载的是3.6.1_bin版本，操作如下：

[root@lucas src]# wget https://archive.apache.org/dist/zookeeper/zookeeper-3.6.1/apache-zookeeper-3.6.1-bin.tar.gz
[root@lucas src]# tar -zxvf apache-zookeeper-3.6.1-bin.tar.gz
[root@lucas src]# mv ./apache-zookeeper-3.6.1-bin /usr/local/zookeeper
[root@lucas local]# cd /usr/local/zookeeper/
[root@lucas zookeeper]# mkdir data
[root@lucas zookeeper]# cd ./conf/
[root@lucas conf]# cp zoo_sample.cfg zoo.cfg
[root@ucas conf]# vim zoo.cfg
# 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/data
# the port at which the clients will connect
clientPort=2181

       将参数dataDir路径设置为/usr/local/zookeeper/data，保存退出。然后启动zookeeper：

[root@lucas conf]# cd ..
[root@lucas zookeeper]# ./bin/zkServer.sh start
ZooKeeper JMX enabled by default
Using config: /usr/local/zookeeper/bin/../conf/zoo.cfg
Starting zookeeper ... STARTED

        至此，zookeeper服务端启动成功。再启动客户端可看到如下响应：

[root@lucas zookeeper]# ./bin/zkCli.sh 
Connecting to localhost:2181
2021-01-10 14:50:58,253 [myid:] - INFO  [main:Environment@98] - Client environment:zookeeper.version=3.6.1--104dcb3e3fb464b30c5186d229e00af9f332524b, built on 04/21/2020 15:01 GMT
2021-01-10 14:50:58,258 [myid:] - INFO  [main:Environment@98] - Client environment:host.name=lucas
2021-01-10 14:50:58,258 [myid:] - INFO  [main:Environment@98] - Client environment:java.version=1.8.0_271
......
Welcome to ZooKeeper!

WatchedEvent state:SyncConnected type:None path:null
[zk: localhost:2181(CONNECTED) 0] 

三、安装kafka

        kafka可从该页面中下载：Index of /kafka

        这里下载的版本是2.12-2.6.0。操作如下：

[root@lucas src]# tar -zxvf kafka_2.12-2.6.0.tgz 
[root@lucas src]# mv ./kafka_2.12-2.6.0 /usr/local/kafka
[root@lucas src]# cd /usr/local/kafka
[root@lucas kafka]# ./bin/kafka-server-start.sh config/server.properties
[2021-01-10 15:03:36,495] INFO Registered kafka:type=kafka.Log4jController MBean (kafka.utils.Log4jControllerRegistration$)
[2021-01-10 15:03:37,315] INFO Setting -D jdk.tls.rejectClientInitiatedRenegotiation=true to disable client-initiated TLS renegotiation (org.apache.zookeeper.common.X509Util)

.....
[2021-01-10 15:03:39,298] INFO [LogDirFailureHandler]: Starting (kafka.server.ReplicaManager$LogDirFailureHandler)

        至此kafka服务端启动成功，可启动如下命令终止kafka服务：

[root@lucas kafka]# ./bin/kafka-server-stop.sh config/server.properties
