storm伪集群环境搭建

准备工作:
1、zookeeper-3.4.10.tar.gz

2、apache-storm-1.1.0.tar.gz

单机模式(伪集群)

  1. 安装zookeeper:

将下载的zookepper安装文件放入/usr/local/目录下并解压文件

root@mylinux local]# tar -zxvf zookeeper-3.4.10.tar.gz

编辑配置文件,创建一个zoo.cfg文件,可从zoo_simple.cfg复制

[root@mylinux local]# cd zookeeper-3.4.10/conf/
[root@mylinux conf]# cp zoo_sample.cfg zoo.cfg
[root@mylinux conf]# vi zoo.cfg

修改配置文件zoo.cfg内容如下:

# 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-3.4.10/data
# 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

只需修改dataDir=/usr/local/zookeeper-3.4.10/data这一行,指定数据存储位置。
启动zookeeper:

[root@mylinux zookeeper-3.4.10]# cd /usr/local/zookeeper-3.4.10
[root@mylinux zookeeper-3.4.10]# ./bin/zkServer.sh start

看到如下信息说明zookeeper启动成功

ZooKeeper JMX enabled by default
Using config: /usr/local/zookeeper-3.4.10/bin/../conf/zoo.cfg
Starting zookeeper ... STARTED

2、安装storm
将storm安装文件放入/usr/local/目录下,并解压文件

[root@mylinux local]# tar -zxvf apache-storm-1.1.0.tar.gz

进入目录下修改配置文件:

[root@mylinux local]# cd apache-storm-1.1.0/conf/
[root@mylinux conf]# vi storm.yaml

在storm.yaml中加入以下配置:

storm.zookeeper.servers:
     - "localhost"

nimbus.seeds: ["localhost"]

drpc.servers:
    - "localhost"

storm.local.dir: "/usr/local/apache-storm-1.1.0/local-dir"

启动storm:

[root@mylinux ~]# cd /usr/local/apache-storm-1.1.0/bin/
[root@mylinux bin]# storm nimbus > /dev/null 2>&1 &
[root@mylinux bin]# storm supervisor > /dev/null 2>&1 &
[root@mylinux bin]# storm drpc > /dev/null 2>&1 &
[root@mylinux bin]# storm ui > /dev/null 2>&1 &

查看启动是否成功(启动较慢,需要多等一会):

[root@mylinux bin]#netstat -lnp |grep java

以下为启动成功界面:

可已通过ui界面查看storm运行状态,浏览器访问:http://ip/8080

如果访问失败关闭防火墙后重试(关闭防火墙命令:service iptables stop)
注:如果启动storm失败可进入storm安装目录logs文件夹下查看失败原因,如:nimbus错误日志在numbus.log,supervisor日志在supervisor.log …
