zookeeper版本升级

原版本: zookeeper-3.4.8

新版本: zookeeper-3.5.7

下载地址: https://downloads.apache.org/zookeeper/zookeeper-3.5.7/apache-zookeeper-3.5.7-bin.tar.gz

第一步: 下载并解压安装包

wget https://downloads.apache.org/zookeeper/zookeeper-3.5.7/apache-zookeeper-3.5.7-bin.tar.gz
tar xf apache-zookeeper-3.5.7-bin.tar.gz -C /usr/local/
cd /usr/local/apache-zookeeper-3.5.7-bin/

第二步: 将原来的配置文件拷贝即可

cp /usr/local/zookeeper/conf/zoo.cfg /usr/local/apache-zookeeper-3.5.7-bin/conf/

第三步: 修改 zkServer.sh 启动文件

vim /usr/local/apache-zookeeper-3.5.7-bin/bin/zkServer.sh
# 在77行添加以下内容
ZOOMAIN="-Dzookeeper.4lw.commands.whitelist=* ${ZOOMAIN}"

第四步: 停止原来zookeeper, 并启动新版本

/usr/local/zookeeper/bin/zkServer.sh stop
/usr/local/apache-zookeeper-3.5.7-bin/bin/zkServer.sh start
echo stat|nc localhost 2181   #查看现在版本
