zookeeper系列之-linux系统服务安装

1.zookeeper下载

下载博主自己用的比较多的zookeeper-3.4.8.tar.gz版本
小生在此，请点击下载，come on！

2.解压下载安装包。

tar -zxvf zookeeper-3.4.8.tar.gz

3.跳转zookeeper-3.4.8目录，新建data文件夹，用作数据存储路径。

[root@instance-n4r06itt zookeeper-3.4.8]# mkdir data

4.拷贝zoo_sample.cfg文件。

[root@instance-n4r06itt conf]# cp zoo_sample.cfg zoo.cfg

5.修改zoo.cfg，添加数据存放路径。

# 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.
# 添加路径
dataDir=/opt/middleware/zookeeper-3.4.8/data
# the port at which the clients will connect
clientPort=2181

6.执行命令，启动、关闭、状态查询。

启动zk：

[root@instance-n4r06itt conf]# cd ../bin/
[root@instance-n4r06itt bin]# ll

[root@instance-n4r06itt bin]# ./zkServer.sh start
ZooKeeper JMX enabled by default
Using config: /opt/middleware/zookeeper-3.4.8/bin/../conf/zoo.cfg
Starting zookeeper ... STARTED

关闭zk：

[root@instance-n4r06itt bin]# ./zkServer.sh stop
ZooKeeper JMX enabled by default
Using config: /opt/middleware/zookeeper-3.4.8/bin/../conf/zoo.cfg
Stopping zookeeper ... ./zkServer.sh: line 182: kill: (28909) - No such process
STOPPED

zk状态查询：

[root@instance-n4r06itt bin]# ./zkServer.sh status
ZooKeeper JMX enabled by default
Using config: /opt/middleware/zookeeper-3.4.8/bin/../conf/zoo.cfg
Error contacting service. It is probably not running.

由于博主用的是新虚拟机，环境是新的，出现问题，不过不要紧，有问题咋就解决，根据上述报错提示，博主得安装JDK，咋就装一个。
jdk系列之-linux系统安装
jdk安装完毕以后，再来尝试启动zookeeper。

[root@instance-n4r06itt bin]# ./zkServer.sh stop
ZooKeeper JMX enabled by default
Using config: /opt/middleware/zookeeper-3.4.8/bin/../conf/zoo.cfg
Stopping zookeeper ... ./zkServer.sh: line 182: kill: (28909) - No such process
STOPPED
[root@instance-n4r06itt bin]# ./zkServer.sh start
ZooKeeper JMX enabled by default
Using config: /opt/middleware/zookeeper-3.4.8/bin/../conf/zoo.cfg
Starting zookeeper ... STARTED
[root@instance-n4r06itt bin]# ./zkServer.sh status
ZooKeeper JMX enabled by default
Using config: /opt/middleware/zookeeper-3.4.8/bin/../conf/zoo.cfg
Mode: standalone
[root@instance-n4r06itt bin]# pwd
/opt/middleware/zookeeper-3.4.8/bin
[root@instance-n4r06itt bin]# 

至此，zookeeper安装，启动成功。
