zookeeper 安装

zookeeper 安装

环境机器三台,系统centos6.5最小安装, 最好先关闭iptables,等部署好以后在安装需求打开.

10.221.8.220

10.221.8.221

10.221.8.222

第一步 准备需要的安装包

zookeeper: http://apache.fayea.com/zookeeper/zookeeper-3.3.6/zookeeper-3.3.6.tar.gz

linux 系统使用wget下载jdk,是个很操蛋的事情. ....   最后google到了一个解决办法.

wget --no-cookies --no-check-certificate --header "Cookie: gpw_e24=http%3A%2F%2Fwww.oracle.com%2F; oraclelicense=accept-securebackup-cookie" "http://download.oracle.com/otn-pub/java/jdk/8u60-b27/jdk-8u60-linux-x64.tar.gz"

第二步安装

 1:安装jdk (解压配置好环境变量即可)

export JAVA_HOME=/usr/share/jdk1.6.0_35

export PATH=$JAVA_HOME/bin:$PATH

export CLASSPATH=.:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar

2:安装zookeeper (解压即可, 我把它移动到 /usr/local/下面)

第一步:修改zookeeper的配置文件  (三台机器的配置都一样)

vi /usr/local/zookeeper-3.3.6/conf/zoo.cfg

# 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.

dataDir=/tmp/zookeeper    #存放数据的目录

dataLogDir=/usr/local/zookeeper-3.3.6/logs

# the port at which the clients will connect

clientPort=2181

server.1=Redis1:2888:3888    #server.1 决定了后面这个主机(Redis1)里面的zookeeper的myid文件里面的内容

server.2=Redis2:2888:3888

server.3=Redis3:2888:3888

第二步: 创建目录与文件 (处了myid 文件里面的内容不样,其他都一样.)

mkdir /usr/local/zookeeper-3.3.6/logs

mkdir /tmp/zookeeper

touch /tmp/zookeeper/myid

echo 1 > /tmp/zookeeper/myid    # 各个机器上的zookeeper的myid文件里面的内容是由配置文件里面这一行( server.1=Redis1:2888:3888 )配置来决定的.  我的这个机器的hostname 是 Redis1 所以使用server.1的这个1 

3 启动zookeeper

/usr/local/zookeeper-3.3.6/bin/zkServer.sh start

/usr/local/zookeeper-3.3.6/bin/zkServer.sh status      #查看状态正常情况如下

JMX enabled by default

Using config: /usr/local/zookeeper-3.3.6/bin/../conf/zoo.cfg

Mode: leader  #也可能是其他角色
