windows10 環境下本機安裝zookeeper。
公司測試服務器的zookeeper 因爲一些未知原因，會偶爾掛掉，然後考慮本機安裝zookeeper服務，用於程序開發。
一. 下載zookeeper 官網地址：http://mirror.bit.edu.cn/apache/zookeeper/
一開始選擇的是zookeeper-3.5.5版本，後來再啓動時，提示加載不到主類，找了些資料，也沒有解決，然後換了zookeeper-3.4.14 試了下，可以啓動服務並應用。
我這邊下載安裝的是zookeeper-3.4.14版本（zookeeper-3.4.14.tar.gz ） http://mirror.bit.edu.cn/apache/zookeeper/zookeeper-3.4.14/
二. 安裝
2.1 將壓縮包解壓到D盤 目錄爲:D:\zookeeper-3.4.14。
2.2 修改D:\zookeeper-3.4.14\conf 下的zoo_sample.cfg 文件。
1）首先將文件名改成 zoo.cfg。
2）打開 zoo.cfg 文件 ，指定臨時數據目錄，修改dataDir=/tmp/zookeeper 爲 dataDir=D:/zookeeper-3.4.14/tmp/zookeeper。
3）其他屬性後期可根據需要修改。
三. 啓動
通過 cmd 進入dos命令窗口。命令窗口模式進入zookeeper的bin目錄下，輸入zkServer.cmd 回車。
C:\Users\hzhb>e:
D:>cd zookeeper-3.4.14/bin
D:\zookeeper-3.4.14\bin>zkServer.cmd
Error: JAVA_HOME is incorrectly set.
D:\zookeeper-3.4.14\bin>call “-Dzookeeper.log.dir=D:\zookeeper-3.4.14\bin…” “-Dzookeeper.root.logger=INFO,CONSOLE” -cp “D:\zookeeper-3.4.14\bin…\build\classes;D:\zookeeper-3.4.14\bin…\build\lib*;D:\zookeeper-3.4.14\bin…*;D:\zookeeper-3.4.14\bin…\lib*;D:\zookeeper-3.4.14\bin…\conf” org.apache.zookeeper.server.quorum.QuorumPeerMain “D:\zookeeper-3.4.14\bin…\conf\zoo.cfg”
‘"-Dzookeeper.log.dir=D:\zookeeper-3.4.14\bin…"’ 不是內部或外部命令，也不是可運行的程序
或批處理文件。
D:\zookeeper-3.4.14\bin>endlocal
D:\zookeeper-3.4.14\bin>
。。。。。報錯了。。。。。
根據異常信息 提示JAVA_HOME 設置錯誤，下面要設置下JAVA_HOME。
打開 D:\zookeeper-3.4.14\bin 下的zkEnv.cmd 文件。然後重新指定JAVA_HOME。
刪掉原來的 set JAVA_HOME=%JAVA_HOME:"=% ，然後修改如下：
@REM setup java environment variables
set JAVA_HOME=“C:\Program Files\Java\jdk1.8.0_131”
if not defined JAVA_HOME (
echo Error: JAVA_HOME is not set.
goto :eof
)
if not exist “%JAVA_HOME%”\bin\java.exe (
echo Error: JAVA_HOME is incorrectly set.
goto :eof
)
REM strip off trailing \ from JAVA_HOME or java does not start
if “%JAVA_HOME:~-1%” EQU “” set “JAVA_HOME=%JAVA_HOME:~0,-1%”
set JAVA="%JAVA_HOME%"\bin\java
然後 回到命令窗口 重新啓動 如下：
D:\zookeeper-3.4.14\bin>zkServer.cmd
系統找不到指定的路徑。
Error: JAVA_HOME is incorrectly set.
D:\zookeeper-3.4.14\bin>call “-Dzookeeper.log.dir=D:\zookeeper-3.4.14\bin…” “-Dzookeeper.root.logger=INFO,CONSOLE” -cp “D:\zookeeper-3.4.14\bin…\build\classes;D:\zookeeper-3.4.14\bin…\build\lib*;D:\zookeeper-3.4.14\bin…*;D:\zookeeper-3.4.14\bin…\lib*;D:\zookeeper-3.4.14\bin…\conf” org.apache.zookeeper.server.quorum.QuorumPeerMain “D:\zookeeper-3.4.14\bin…\conf\zoo.cfg”
‘"-Dzookeeper.log.dir=D:\zookeeper-3.4.14\bin…"’ 不是內部或外部命令，也不是可運行的程序
或批處理文件。
D:\zookeeper-3.4.14\bin>endlocal
D:\zookeeper-3.4.14\bin>
。。。。。發現還是報錯 系統找不到指定的路徑。。。。。。。
然後看配置文件是
if not exist “%JAVA_HOME%”\bin\java.exe (
echo Error: JAVA_HOME is incorrectly set.
goto :eof
)
報的錯誤，將路徑修改下，去掉 “%JAVA_HOME%” 的雙引號 改成 %JAVA_HOME% 如下：
@REM setup java environment variables
set JAVA_HOME=“C:\Program Files\Java\jdk1.8.0_131”
if not defined JAVA_HOME (
echo Error: JAVA_HOME is not set.
goto :eof
)
if not exist %JAVA_HOME%\bin\java.exe (
echo Error: JAVA_HOME is incorrectly set.
goto :eof
)
REM strip off trailing \ from JAVA_HOME or java does not start
if “%JAVA_HOME:~-1%” EQU “” set “JAVA_HOME=%JAVA_HOME:~0,-1%”
set JAVA=%JAVA_HOME%\bin\java
然後 回到命令窗口 重新啓動 如下：
D:\zookeeper-3.4.14\bin>zkServer.cmd
此時不應有 =“C:\Program Files\Java\jdk1.8.0_131”。
D:\zookeeper-3.4.14\bin>
。。。。。。
還是有問題，在這個地方，想了好一會也不清楚問題在哪裏，後來分析下唯一可能出問題的地方 也就是
REM strip off trailing \ from JAVA_HOME or java does not start
if “%JAVA_HOME:~-1%” EQU “” set “JAVA_HOME=%JAVA_HOME:~0,-1%”
看下這句話大概是說如果JAVA_HOME滿足什麼條件，給JAVA_HOME賦值，個人覺着 JAVA_HOME 上面已經配好，可以不管這句，就把它刪掉了。。。。。
然後 回到命令窗口 重新啓動 如下：
D:\zookeeper-3.4.14\bin>zkServer.cmd
D:\zookeeper-3.4.14\bin>call “D:\java\JDK”\bin\java “-Dzookeeper.log.dir=D:\zookeeper-3.4.14\bin…” “-Dzookeeper.root.logger=INFO,CONSOLE” -cp “D:\zookeeper-3.4.14\bin…\build\classes;D:\zookeeper-3.4.14\bin…\build\lib*;D:\zookeeper-3.4.14\bin…*;D:\zookeeper-3.4.14\bin…\lib*;D:\zookeeper-3.4.14\bin…\conf” org.apache.zookeeper.server.quorum.QuorumPeerMain “D:\zookeeper-3.4.14\bin…\conf\zoo.cfg”

啓動成功！
然後將項目中的原來的zookeeper 地址換成 當前配置 127.0.0.1:2181 即可。
