以下是zookeeper的zoo.cfg配置
# 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/zookeeper/zkData
dataLogDir=/opt/zookeeper/zkLog
# 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
## Metrics Providers
#
# https://prometheus.io Metrics Exporter
#metricsProvider.className=org.apache.zookeeper.metrics.prometheus.PrometheusMetricsProvider
#metricsProvider.httpPort=7000
#metricsProvider.exportJvmInfo=true
zkData、和zkLog也都有

但是启动时还是报错，究竟是什么问题呢？

我的解答思路和尝试过的方法
网上的搜索方案基本丢失，检查防火墙，还有删除什么ID，也都尝试过，
有没有可能是安装MySQL导致的占用端口，因为之前先安装的zookeeper，可以正常启动，集群也能正常启动
但是在安装mysql后，不知道是不是这个原因
我想要达到的结果
如何才能正常启动zookeeper
