在所有的机器上面执行下面步骤：

1.上传zookeeper和jdk, /opt/soft/

2.解压jdk和zookeeper

tar xf xxxx

3.配置jdk环境变量：

vi /etc/profile
export JAVA_HOME=/opt/soft/jdk/jdk1.8.0_181
export PATH=$JAVA_HOME/bin/:$PATH

然后source  /etc/profile

java -version看能否打印正确信息

 4.配置zookeeper, /conf/zoo.cfg,红色部分是需要修改的内容

# 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=/opt/soft/zookeeper-3.4.13/data
dataLogDir=/opt/soft/zookeeper-3.4.13/datalog
# 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
server.1=10.192.126.144:2888:3888
server.2=10.192.126.145:2888:3888
server.3=10.192.126.146:2888:3888
server.4=10.192.126.147:2888:3888
server.5=10.192.126.148:2888:3888

5.创建目录

mkdir -p /opt/soft/zookeeper-3.4.13/data

mkdir -p /opt/soft/zookeeper-3.4.13/datalog

执行下面步骤 数字是和上面标红配置一致。

例如10.192.126.144机器执行 echo 1 > /opt/soft/zookeeper-3.4.13/data/myid

例如10.192.126.145机器执行 echo 2 > /opt/soft/zookeeper-3.4.13/data/myid

后边类似。

echo 3 > /opt/soft/zookeeper-3.4.13/data/myid

echo 4 > /opt/soft/zookeeper-3.4.13/data/myid

echo 5 > /opt/soft/zookeeper-3.4.13/data/myid

综上，整体配置已经完成，直接到 bin/zkServer.sh start 就行了。

bin/zkServer.sh status查看状态。

如果zookeeper用systemctl管理，查看另一篇文章：
