Ubuntu18.04 搭建zookeeper单机版集群

1.下载安装包

sudo wget -b http://archive.apache.org/dist/zookeeper/zookeeper-3.4.9/zookeeper-3.4.9.tar.gz -o /opt/archive/zookeeper.download.log

2.创建数据及日志目录并修改权限

# 同时为创建3*2=6个目录
sudo mkdir /data/{zk1,zk2,zk3}/{data,logs}
# 修改权限为当前用户所有
sudo chown -R $USER:$GROUPS /data/{zk1,zk2,zk3}

3.指定myid

echo "1" > /data/zk1/data/myid
echo "2" > /data/zk2/data/myid
echo "3" > /data/zk3/data/myid

4.复制并修改配置文件

cp /opt/zk/conf/zoo_sample.cfg /data/zk1/zoo.cfg

5.配置文件

# The number of milliseconds of each tick
# 心跳间隔
tickTime=2000

# The number of ticks that the initial 
# synchronization phase can take
# 初始同步阶段的心跳间隔
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.
# 存储快照的目录，不要使用/tmp目录
dataDir=/data/zk1/data
dataLogDir=/data/zk1/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
#
# 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

# 心跳端口，数据端口;选举完成后，每个节点打开数据端口;只有主节点打开心跳端口，接受心跳数据
# server.N 和 myid 是对应的
server.1=bogon:2888:3888
server.2=bogon:2889:3889
server.3=bogon:2890:3890

6.批量操作脚本

for zk in {1,2,3}
do
    myid=/data/zk${zk}/data/myid
    if [ ! -e "$myid" ];then
        echo $zk > $myid
    fi
    zkServer.sh $1 /data/zk${zk}/zoo.cfg
done
