解决centos7启动zookeeper 报错

启动zookeeper报错 Failed to start zookeeper.service: Unit not found.

运行环境：centos 7.0 | jdk 1.8 | zookeeper 4.2.1

zookeeper 已经安装成功启动时报错。

运行 #systemctl start zookeeper后显示： # Failed to start zookeeper.service: Unit not found.

jps后也没有QuorumPeerMain进程

#zkServer.sh status查看，反馈如下： #JMX enabled by default 先后检查配置文件 conf/zoo.cfg 、 ../data/myid:

tickTime=2000

initLimit=5

syncLimit=2

dataDir=/opt/zookeeper/data

dataLogDir=/opt/zookeeper/logs

clientPort=2181

server.1=192.168.88.128:2888:3888

server.2=192.168.88.129:2888:3888

server.3=192.168.88.130:2888:3888

----------------------------------------

myid文件分别为1、2、3

三个节点中两个配置文件没有错误。

检查/etc/profile jdk和zookeeper的配置环境

#JDK1.8 configuration JAVA_HOME=/usr/jdk1.8 JRE_HOME=$JAVA_HOME/jre PATH=$PATH:$JAVA_HOME/bin CLASSPATH=.:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar export JAVA_HOME export JRE_HOME export PATH export CLASSPATH

ZOOKEEPER_HOME=/opt/zookeeper export PATH=$ZOOKEEPER_HOME/bin:$PATH export ZOOKEEPER_HOME export PATH

都没问题，最后

source下profile文件 在启动zookeeper启动成功
