dubbo 第一天，安装Zookeeper

1.配置本地主机别名

cd /etc

vi hosts

#zookeeper services
192.168.1.105 eud-provide-01

 

2、创建 /usr/local/services/zookeeper 文件夹：

mkdir -p /usr/local/services/zookeeper
3、进入到 /usr/local/services/zookeeper 目录中：

cd /usr/local/services/zookeeper
4、下载 zookeeper-3.4.9.tar.gz：

wget http://apache.fayea.com/zookeeper/zookeeper-3.4.11/zookeeper-3.4.11.tar.gz

5、解压缩 zookeeper-3.4.9.tar.gz：

tar -zxvf zookeeper-3.4.9.tar.gz

6、进入到 /usr/local/services/zookeeper/zookeeper-3.4.9/conf 目录中：

cd zookeeper-3.4.9/conf/

7、复制 zoo_sample.cfg 文件的并命名为为 zoo.cfg：

cp zoo_sample.cfg zoo.cfg

8、用 vim 打开 zoo.cfg 文件并修改其内容为如下：

# The number of milliseconds of each tick

# zookeeper 定义的基准时间间隔，单位：毫秒

tickTime=2000

# The number of ticks that the initial

# synchronization phase can take

initLimit=10

# The number of ticks that can pass betwee

# sending a request and getting an acknowledgement

yncLimit=5
# the directory where the snapshot is stored.
# do not use /tmp for storage, /tmp here is just
# example sakes.
# dataDir=/tmp/zookeeper
# 数据文件夹
dataDir=/usr/local/services/zookeeper/zookeeper-3.4.9/data
# 日志文件夹
dataLogDir=/usr/local/services/zookeeper/zookeeper-3.4.9/log
# the port at which the clients will connect
# 客户端访问 zookeeper 的端口号
clientPort=2181
# the maximum number of client connections.
# increase this if you need to handle more client
#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 hour
# Set to "0" to disable auto purge feature
 #autopurge.purgeInterval=1

9、保存并关闭 zoo.cfg 文件:

10、进入到 /usr/local/services/zookeeper/zookeeper-3.4.9/bin 目录中：

cd ../bin/

11、用 vim 打开 /etc/ 目录下的配置文件 profile：

vim /etc/profile

并在其尾部追加如下内容：

# idea - zookeeper-3.4.9 config start - 2016-09-08

export ZOOKEEPER_HOME=/usr/local/services/zookeeper/zookeeper-3.4.9/

export PATH=$ZOOKEEPER_HOME/bin:$PATH

export PATH

# idea - zookeeper-3.4.9 config start - 2016-09-08

12、使 /etc/ 目录下的 profile 文件即可生效：

source /etc/profile

13、启动 zookeeper 服务：
zkServer.sh start
如打印如下信息则表明启动成功：
ZooKeeper JMX enabled by default
Using config: /usr/local/services/zookeeper/zookeeper-3.4.9/bin/../conf/zoo.cfg     Starting zookeeper ... STARTED

 
13、查询 zookeeper 状态：
zkServer.sh statu
14、关闭 zookeeper 服务：
zkServer.sh sto
如打印如下信息则表明成功关闭：
ZooKeeper JMX enabled by default
Using config: /usr/local/services/zookeeper/zookeeper-3.4.9/bin/../conf/zoo.cfg
Stopping zookeeper ... STOPPED
15、重启 zookeeper 服务：
zkServer.sh restart
