linux系统安装zookeeper

1. 新建/usr/loca/zookeeper文件夹
[root@localhost ~]# mkdir -pv /usr/local/zookeeper

2.拷贝文件到指定文件夹
[root@localhost ~]# cd /root/Desktop/
[root@localhost ~]# cp ./zookeeper-3.4.6.tar.gz /usr/local/zookeeper

3. 解压
[root@localhost ~]# tar -zxvf jdk-8u121-linux-x64.tar.gz

4. 配置环境变量
[root@localhost ~]#cd /etc/
[root@localhost ~]#cp ./profile ./profile.bak -- 把文件备份一下
[root@localhost ~]#vi /etc/profile -- 编辑此配置文件
在文件末尾添加此段内容: -- 开始和--中间的一段.(注意,尽量保持环境变量名全大写,下划线隔开. 保持规范)
-- 开始
export ZOOKEEPER_INSTALL=/usr/local/zookeeper/zookeeper-3.4.6/
export PATH=$PATH:$ZOOKEEPER_INSTALL/bin
-- 结束

5. 配置文件修改
[root@localhost zookeeper-3.4.6]# cd /usr/local/zookeeper/zookeeper-3.4.6/conf/ -- 进入文件所在路径
[root@localhost conf]# cp zoo_sample.cfg zoo.cfg -- 将zoo.sample.cfg拷贝出一份zoo.cfg出来. 文件名强制

6. 文件内容如下:
[root@localhost conf]# vi zoo.cfg -- 按i进入编辑模式. 修改完成之后, esc退出编辑模式, 大写字母Z双击即可保存.

# 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=/tmp/zookeeper -- 这里要设置一下文件路径 路径必须存在,不存在的话就新建一个呗
dataLogDir=/tmp/zookeeper/log -- 日志路径 路径必须存在,不存在的话就新建一个呗
# the port at which the clients will connect
clientPort=2181 -- 如果是多机器的话,在clientPort处添加服务器的ip
# 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

修改完之后 通过 > # cat zoo.cfg 查看.


7. 开启服务,关闭服务, 查看
[root@localhost bin]# cd /usr/local/zookeeper/zookeeper.3.4.14/bin/
[root@localhost bin]# ./zkServer.sh stop -- 停止服务
JMX enabled by default
Using config: /usr/local/zookeeper/zookeeper-3.4.6/bin/../conf/zoo.cfg
Stopping zookeeper ... STOPPED

[root@localhost bin]# ./zkServer.sh start -- 开启服务
JMX enabled by default
Using config: /usr/local/zookeeper/zookeeper-3.4.14/bin/../conf/zoo.cfg
Starting zookeeper ... STARTED

[root@localhost bin]# ./zkServer.sh status -- 查看状态
