[root@mall ~]# tar -zxvf zookeeper-3.4.14.tar.gz

进入到zookeeper-3.4.14/conf目录下，将zoo_sample.cfg文件重命名为zoo.cfg，命令如下：

[root@mall conf]# cd zookeeper-3.4.14/conf

[root@mall conf]# mv zoo_sample.cfg zoo.cfg

进入到zookeeper-3.4.14/bin目录下，启动ZooKeeper服务，命令如下：

[root@mall conf]# cd zookeeper-3.4.14/bin

[root@mall bin]# ./zkServer.sh start

ZooKeeper JMX enabled by default

Using config: /root/zookeeper-3.4.14/bin/../conf/zoo.cfg

Starting zookeeper ... STARTED

查看ZooKeeper状态，命令如下：

[root@mall bin]# ./zkServer.sh status

ZooKeeper JMX enabled by default

Using config: /root/zookeeper-3.4.14/bin/../conf/zoo.cfg

Mode: standalone

[root@mall]# tar -zxvf kafka_2.11-1.1.1.tgz

进入到kafka_2.11-1.1.1/bin目录下，启动Kafka服务，命令如下：

[root@mall]# cd kafka_2.11-1.1.1/bin

[root@mall bin]# ./kafka-server-start.sh -daemon ../config/server.properties

使用netstat –ntpl命令查看Kafka是否成功启动，运行结果查看到Kafka服务和9092端口，说明Kafka服务已启动，如下图所示：

[root@mall bin]# netstat -ntpl

NOTE: RUNNING ALL PARTS OF THIS SCRIPT IS RECOMMENDED FOR ALL MariaDB

      SERVERS IN PRODUCTION USE!  PLEASE READ EACH STEP CAREFULLY!

 

In order to log into MariaDB to secure it, we'll need the current

password for the root user.  If you've just installed MariaDB, and

you haven't set the root password yet, the password will be blank,

so you should just press enter here.

 

Enter current password for root (enter for none): //默认按回车

OK, successfully used password, moving on...

 

Setting the root password ensures that nobody can log into the MariaDB

root user without the proper authorisation.

 

Set root password? [Y/n] y

New password: //输入密码000000

Re-enter new password: //再次输入000000

Password updated successfully!

Reloading privilege tables..

 ... Success!

 

 

By default, a MariaDB installation has an anonymous user, allowing anyone

to log into MariaDB without having to have a user account created for

them.  This is intended only for testing, and to make the installation

go a bit smoother.  You should remove them before moving into a

production environment.

 

Remove anonymous users? [Y/n] y //默认回车

 ... Success!

 

Normally, root should only be allowed to connect from 'localhost'.  This

ensures that someone cannot guess at the root password from the network.

 

Disallow root login remotely? [Y/n] //默认回车

 ... Success!

 

By default, MariaDB comes with a database named 'test' that anyone can

access.  This is also intended only for testing, and should be removed

before moving into a production environment.

 

Remove test database and access to it? [Y/n] //默认回车

 - Dropping test database...

 ... Success!

 - Removing privileges on test database...

 ... Success!

 

Reloading the privilege tables will ensure that all changes made so far

will take effect immediately.

 

Reload privilege tables now? [Y/n] //默认回车

 ... Success!

 

Cleaning up...

 

All done!  If you've completed all of the above steps, your MariaDB

installation should now be secure.

 

Thanks for using MariaDB! //数据库配置完毕
