１、拉去分支代码到idea中
https://github.com/apache/zookeeper.git
２、源码导入idea后，org.apache.zookeeper.Version类会报错，需要建一个辅助类（如果源代码不报错忽略此类）
package org.apache.zookeeper.version;
public interface Info {
int MAJOR = 1;
int MINOR = 0;
int MICRO = 0;
String QUALIFIER = null;
int REVISION =-1;
String REVISION_HASH = "1";
String BUILD_DATE = "2020‐10‐15";
}
3、在源代码根目录执行命令行进行编译
mvn clean install ‐DskipTes
４、启动之前需要先将zookeeper-server项目里pom.xml文件里依赖的包(除了jline)的scope为provided这一行全部注释掉
<?xml version="1.0" encoding="UTF-8"?>

５、将conf文件夹里的log4j.properties文件复制一份到zookeeper-server项目的resource 目录下(注意resource目录的点亮)，这样项目启动时才会打印日志
６、配置conf配置文件
zoo1.cfg文件如下zoo2\zoo3只需修改dataDir、dataLogDir、clientPort(注意目录不能有中文)
# 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
dataDir=/home/kangcc/Desktop/homework/zookeeper/conf/zk1/data
dataLogDir=/home/kangcc/Desktop/homework/zookeeper/conf/zk1/log
# the port at which the clients will connect
clientPort=2181
server.1=localhost:2887:3887
server.2=localhost:2888:3888
server.3=localhost:2889:3889
# 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
## Metrics Providers
#
# https://prometheus.io Metrics Exporter
#metricsProvider.className=org.apache.zookeeper.metrics.prometheus.PrometheusMetricsProvider
#metricsProvider.httpPort=7000
#metricsProvider.exportJvmInfo=true
７、配置三个启动类分别指定各自配置文件
测试：
启动QuorumPeerMain1、QuorumPeerMain２
可以看到启动成功
