Mac安装配置zookeeper

 

因为有用到 dubbo 这个分布式服务框架，所以去网上看了一些教程。
教程地址，自己一步步跟着做，但是搭建 zookeeper+dubbo-admin 的时候犯了好多错误，特地分享一下。

搭建

• zookeeper 搭建
  我用的是 zookeeper 3.4.6 版本的。下载下来解压，把 conf 文件夹下的 zoo_sample.cfg 文件重命名为 zoo.cfg，然后修改文件为

# 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=/usr/local/zookeeper-3.4.6/data/ dataLogDir=/usr/local/zookeeper-3.4.6/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

# 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=/usr/local/zookeeper-3.4.6/data/ dataLogDir=/usr/local/zookeeper-3.4.6/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 

其中 data 和 logs 是自己新建的文件夹.
启动：cd 到 zookeeper 文件夹下，然后./bin/zkServer.sh start 就启动了，检验启动成功与否，输入命令 jps，出现622 QuorumPeerMain字样就是说明成功了。

• dubbo-admin 打包
  我自己操作的错误都发生在这里，问题就是 war 不对。

1. 网上有很多正确的 war 可以下载
2. 自己去官网下载 dubbo 的源文件，然后自己打包

我启动 zookeeper 之后，再启动 tomcat，发生了很多不一的错误，具体错误信息，我没记录下来，也不准备提，归结于 war 包不对，主要是两种方式不对

1. mvn install -Dmaven.test.skip=true 这命令的位置不对。正确应该是dubbo-master文件夹下打包，这样就不会缺少依赖，而不是去dubbo-master/dubbo-admin下面打包。
2. jdk 版本，我的 Mac 是装了两个，1.7 和 1.8，但是我默认是 1.8，导致不对。我切换到 1.7 后就 OK 了。
