0.系統環境配置

0.1
所有伺服器之間配置hosts，新增所有伺服器的ip和hostname對映，如：
vi /etc/hosts
192.168.68.1 b1
0.2
配置limits
vi /etc/security/limits.conf
配置為

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

1.目標

在一臺Linux機器上啟動三臺zookeeper伺服器，啟動三臺kafka，並且做一個簡單的測試。

2.linux機器配置

Red Hat Enterprise Linux Server release 6.4 (Santiago)

[email protected] bin]# ./zkServer.sh start 
JMX enabled by default
Using config: /opt/zookeeper/zookeeper-3.4.6/bin/../conf/zoo.cfg
Starting zookeeper ... STARTED
[[email protected] 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.
重新配置下系統環境配置
僅僅啟動一臺就檢視狀態會報錯：
[[email protected] 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.
直接啟動三臺再去檢查狀態沒有問題：
[[email protected] bin]# ./zkServer.sh status ../conf/zoo3.cfg 
JMX enabled by default
Using config: ../conf/zoo3.cfg
Mode: follower
[[email protected] bin]# ./zkServer.sh status ../conf/zoo2.cfg 
JMX enabled by default
Using config: ../conf/zoo2.cfg
Mode: leader
[[email protected] bin]# ./zkServer.sh status ../conf/zoo.cfg 
JMX enabled by default
Using config: ../conf/zoo.cfg
Mode: follower

至此zookeeper啟動成功。

kafka的部署和zookeeper的操作類似。也可以在一臺機器上部署三個，然後按照參考文件操作即可。
