可选用的 清华大学软件站 https://mirror.tuna.tsinghua.edu.cn/help/centos/ 或者阿里云 http://mirrors.aliyun.com/
一般需要安装的 CentOS-Base.repo
# CentOS-Base.repo # # The mirror system uses the connecting IP address of the client and the # update status of each mirror to pick mirrors that are updated to and # geographically close to the client. You should use this for CentOS updates # unless you are manually picking other mirrors. # # If the mirrorlist= does not work for you, as a fall back you can try the # remarked out baseurl= line instead. # # [base] name=CentOS-$releasever - Base baseurl=https://mirrors.tuna.tsinghua.edu.cn/centos/$releasever/os/$basearch/ #mirrorlist=http://mirrorlist.centos.org/?release=$releasever&arch=$basearch&repo=os gpgcheck=1 gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-7 #released updates [updates] name=CentOS-$releasever - Updates baseurl=https://mirrors.tuna.tsinghua.edu.cn/centos/$releasever/updates/$basearch/ #mirrorlist=http://mirrorlist.centos.org/?release=$releasever&arch=$basearch&repo=updates gpgcheck=1 gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-7 #additional packages that may be useful [extras] name=CentOS-$releasever - Extras baseurl=https://mirrors.tuna.tsinghua.edu.cn/centos/$releasever/extras/$basearch/ #mirrorlist=http://mirrorlist.centos.org/?release=$releasever&arch=$basearch&repo=extras gpgcheck=1 gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-7 #additional packages that extend functionality of existing packages [centosplus] name=CentOS-$releasever - Plus baseurl=https://mirrors.tuna.tsinghua.edu.cn/centos/$releasever/centosplus/$basearch/ #mirrorlist=http://mirrorlist.centos.org/?release=$releasever&arch=$basearch&repo=centosplus gpgcheck=1 enabled=0 gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-7用上文中的内容，替换原有的centos-base.repo 之后 epel 包需要安装
yum makecache yum install -y epel然后修改epel的内容为期望的镜像源。
mv epel.repo epel.repo.bak vim epel.repo然后增加如下内容：
[epel] name=Extra Packages for Enterprise Linux 7 - $basearch baseurl=https://mirrors.tuna.tsinghua.edu.cn/epel/7/$basearch #mirrorlist=https://mirrors.fedoraproject.org/metalink?repo=epel-7&arch=$basearch failovermethod=priority enabled=1 gpgcheck=1 gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-EPEL-7 [epel-debuginfo] name=Extra Packages for Enterprise Linux 7 - $basearch - Debug baseurl=https://mirrors.tuna.tsinghua.edu.cn/epel/7/$basearch/debug #mirrorlist=https://mirrors.fedoraproject.org/metalink?repo=epel-debug-7&arch=$basearch failovermethod=priority enabled=0 gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-EPEL-7 gpgcheck=1 [epel-source] name=Extra Packages for Enterprise Linux 7 - $basearch - Source baseurl=https://mirrors.tuna.tsinghua.edu.cn/epel/7/SRPMS #mirrorlist=https://mirrors.fedoraproject.org/metalink?repo=epel-source-7&arch=$basearch failovermethod=priority enabled=0 gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-EPEL-7 gpgcheck=1都更新之后，执行yum -y update 将yum的源更新为最新。
个人认为比较常用的一些软件为： lsb_release 红帽默认会有这个命令，能方便查看操作系统信息，centos是不带的，需要自行安装：
yum install -y redhat-lsb监控类软件 nmon atop htop iotop
yum -y install nmon atop htop iotop故障分析类软件 telnet mtr
yum -y install telnet mtr安装基础类库，glibc-headers openssl-devel bzip2-devel readline-devel sqlite-devel bison cmake 注意，CentOS会带很多基础包，但都不是devel版本，安装devel版本是为了后续需要根据源码编译安装软件来试用，如根据源码安装mysql等，就需要很多基础库。
yum install sqlite-devel yum install glibc-headers -y yum install gcc-c++ -y yum install openssl-devel -y yum install readline-devel -y yum install bzip2-devel -y yum install bison cmake -y常用软件是指开发人员常用的如 jdk python 等开发工具。

通常情况下，会建立一个zookeeper单独运行用户。
#一般根据服务器磁盘的挂载目录，会将数据盘挂载到/opt 在root权限下运行如下命令，或者用sudo方式 useradd -d /opt/zookeeper zookeeper将zookeeper 软件下载到 /opt/software目录。 需要注意的是，新版本3.5.6的zookeeper apache-zookeeper-3.5.6-bin.tar.gz 才是可以直接启动的编译后的文件，而apache-zookeeper-3.5.6.tar.gz则是源码，可以自行用maven编译。
#切换用户 sudo su - zookeeper #解压 tar -zxvf /opt/software/apache-zookeeper-3.5.6-bin.tar.gz /opt/zookeeper/ #建立软链接，便于后续升级更换 ln -s /opt/zookeeper/apache-zookeeper-3.5.6-bin /opt/zookeeper/apache-zookeeper #新建 data logs 目录，分别用于存放zookeeper的数据和日志 mkdir /opt/zookeeper/data mkdir /opt/zookeeper/logs目前有3台服务器，zookeeper均执行上述操作，之后，zookeeper需要对各个节点分配id，通过一个myid的文件存储在data目录。 修改后的zoo.conf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=/opt/zookeeper/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 server.1=192.168.162.201:2888:3888 server.2=192.168.162.202:2888:3888 server.3=192.168.162.203:2888:3888dataDir路径需要修改为指定目录。 之后根据上述对应关系生成myid。
#在192.168.162.201服务器执行 echo '1' > /opt/zookeeper/data/myid #在192.168.162.202服务器执行 echo '2' > /opt/zookeeper/data/myid 在192.168.162.203服务器执行 echo '3'另外为了让zookeeper的日志能产生在指定的日志目录，还需要将zkEnv.sh 文件进行修改： 将 将ZOO_LOG_DIR 修改为：
if [ "x${ZOO_LOG_DIR}" = "x" ] then ZOO_LOG_DIR="/opt/zookeeper/logs" fi之后，分别在三台服务器上启动zookeeper
/opt/zookeeper/apache-zookeeper/bin/zkServer.sh startstorm通过wget的方式，下载到/opt/software目录，完整路径为：/opt/software/apache-storm-1.2.3.tar.gz
#一般根据服务器磁盘的挂载目录，会将数据盘挂载到/opt 在root权限下运行如下命令，或者用sudo方式 useradd -d /opt/storm storm sudo su - storm #解压缩 tar -zxvf /opt/software/apache-storm-1.2.3.tar.gz ./ #建立软链接 一定要用软链接的方式，便于以后程序升级。 ln -s /opt/storm/apache-storm-1.2.3 /opt/storm/apache-stormstorm有很多配置选项，默认的配置项可以参考git https://github.com/apache/storm/blob/v1.2.3/conf/defaults.yaml 根据服务器信息，基本配置如下：
#storm本地存储目录 storm.local.dir: "/opt/storm/data" #zookeeper服务 storm.zookeeper.servers: - "192.168.162.201" - "192.168.162.202" - "192.168.162.203" #zookeeper端口，注意，不支持各节点用不同的端口，zk不要弄得太奇怪 storm.zookeeper.port: 2181 #nimbus的种子节点，这个地方要填host名称，否则UI展示会有问题 nimbus.seeds : ["m162p201","m162p202","m162p203"] #UI的监听IP及端口 ui.host: 0.0.0.0 ui.port: 8087 #如果有统一的日志采集工具，可以不用开logviewer logviewer.port: 8000 #supervisor 槽 supervisor.slots.ports: - 6700 - 6701 - 6702 - 6703因为上述配置中使用了各节点的hostname,因此需要在hosts中配置，都需要加上：
192.168.162.201 m162p201 192.168.162.202 m162p202 192.168.162.203 m162p203环境变量配置： 修改.bash_profile 增加如下内容
STORM_HOME=/opt/storm/apache-storm PATH=$PATH:$STORM_HOME/bin export PATH之后重新加载环境变量
source .bash_profileUI只需要启动一个节点即可，其他服务器都启动nimbus和supervisor. 至此，storm集群已搭建完毕。
