1、下载源码
官网下载地址: http://mirrors.hust.edu.cn/apache/zookeeper/ 选择最新的版本进行下载
这里选择3.4.10进行下载:
wget http://mirrors.hust.edu.cn/apache/zookeeper/zookeeper-3.4.10/zookeeper-3.4.10.tar.gz
下载完成后执行以下命令进行解压:
tar -zxvf zookeeper-3.4.10.tar.gz
2、配置Zookeeper
解压之后,在zookeeper目录下创建以下目录:
-
[fendo@localhost ~]$ cd zookeeper-3.4.10/
-
[fendo@localhost zookeeper-3.4.10]$ mkdir data
-
[fendo@localhost zookeeper-3.4.10]$ mkdir logs
将zookeeper-3.4.10/conf目录下的zoo_sample.cfg文件拷贝一份,命名为zoo.cfg
[fendo@localhost conf]$ cp zoo_sample.cfg zoo.cfg
然后修改zoo.cfg文件
vim zoo.cfg
修改成如下
-
# 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=/home/fendo/zookeeper-3.4.10/data
-
dataLogDir=/home/fendo/zookeeper-3.4.10/logs
-
# 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
-
server.1=192.168.84.130:2888:3888
其中:
2888端口号是zookeeper服务之间通信的端口。
3888是zookeeper与其他应用程序通信的端口。
然后在dataDir=/home/fendo/zookeeper-3.4.10/data下创建myid文件(编辑myid文件,并在对应的IP的机器上输入对应的编号。如在zookeeper上,myid 文件内容就是1。如果只在单点上进行安装配置,那么只有一个server.1)
vim myid
fendo用户下修改.bash_profile,增加zookeeper配置:
vim /home/fendo/.bash_profile
-
# zookeeper env export
-
ZOOKEEPER_HOME=/home/fendo/zookeeper-3.4.10 export
-
PATH=$ZOOKEEPER_HOME/bin:$PATH
使配置文件生效
source /home/fendo/.bash_profile
关闭防火墙
切换到root用户下,执行以下命令:
systemctl stop firewalld.service
3、测试Zookeeper
启动并测试zookeeper(要用普通用户启动,不要用root):
-
#使用fendo用户到/home/fendo/zookeeper-3.4.10/bin目录中执行
-
./zkServer.sh start
-
-
#查看进程
-
jps
-
-
其中,QuorumPeerMain是zookeeper进程,启动正常。
-
-
#查看状态
-
./zkServer.sh status
-
-
#服务器输出信息
-
tail -500f zookeeper.out
-
-
#停止zookeeper进程
-
./zkServer.sh stop
设置zookeeper服务开机启动
-
# 切换到/etc/rc.d/init.d/目录下
-
cd /etc/rc.d/init.d
-
-
# 创建zookeeper文件
-
touch zookeeper
-
-
#更新权限
-
chmod +x zookeeper
-
-
#编辑文件,在zookeeper里面输入如下内容
-
#!/bin/bash
-
#chkconfig:2345 20 90
-
#description:zookeeper
-
#processname:zookeeper
-
export JAVA_HOME=/user/local/java/jdk1.7.0_79
-
export PATH=$JAVA_HOME/bin:$PATH
-
case $1 in
-
start)su root /home/fendo/zookeeper-3.4.10/bin/zkServer.sh start;;
-
stop)su root /home/fendo/zookeeper-3.4.10/bin/zkServer.sh stop;;
-
status)su root /home/fendo/zookeeper-3.4.10/bin/zkServer.sh status;;
-
restart)su root /home/fendo/zookeeper-3.4.10/bin/zkServer.sh restart;;
-
*) echo "require start|stop|status|restart" ;;
-
esac
然后我们就可以用service zookeeper start/stop来启动停止zookeeper服务了
使用命令把zookeeper添加到开机启动里面
-
chkconfig zookeeper on
-
chkconfig --add zookeeper
添加完成之后接这个使用chkconfig --list 来看看我们添加的zookeeper是否在里面。
