zookeeper一台机器启动三台zookeeper同时类似操作kafka

0.系统环境配置

0.1
所有服务器之间配置hosts，添加所有服务器的ip和hostname映射，如：
vi /etc/hosts
192.168.68.1 b1
0.2
配置limits
vi /etc/security/limits.conf
配置为

# End of file
#
   * soft nofile 500000
   * hard nofile 500000
   * soft nproc 65535
   * hard nproc 65535

1.目标

在一台Linux机器上启动三台zookeeper服务器，启动三台kafka，并且做一个简单的测试。

2.linux机器配置

3.步骤

[root@mbankpush01 zookeeper-3.4.6]# ll conf

drwxr-xr-x 10 root root 4096 Nov 26 17:38 zookeeper-3.4.6
[root@mbankpush01 bin]# ./zkServer.sh start 
JMX enabled by default
Using config: /opt/zookeeper/zookeeper-3.4.6/bin/../conf/zoo.cfg
Starting zookeeper ... STARTED
[root@mbankpush01 bin]# ./zkServer.sh status
JMX enabled by default
Using config: /opt/zookeeper/zookeeper-3.4.6/bin/../conf/zoo.cfg
Error contacting service. It is probably not running.
重新配置下系统环境配置
仅仅启动一台就查看状态会报错：
[root@mbankpush01 bin]# ./zkServer.sh status
JMX enabled by default
Using config: /opt/zookeeper/zookeeper-3.4.6/bin/../conf/zoo.cfg
Error contacting service. It is probably not running.
直接启动三台再去检查状态没有问题：
[root@mbankpush01 bin]# ./zkServer.sh status ../conf/zoo3.cfg 
JMX enabled by default
Using config: ../conf/zoo3.cfg
Mode: follower
[root@mbankpush01 bin]# ./zkServer.sh status ../conf/zoo2.cfg 
JMX enabled by default
Using config: ../conf/zoo2.cfg
Mode: leader
[root@mbankpush01 bin]# ./zkServer.sh status ../conf/zoo.cfg 
JMX enabled by default
Using config: ../conf/zoo.cfg
Mode: follower

至此zookeeper启动成功。

kafka的部署和zookeeper的操作类似。也可以在一台机器上部署三个，然后按照参考文档操作即可。
