shell脚本一键安装zookeeper3.4.5
上篇shell脚本写了一键安装solr，本篇我们来看下如何一键安装zookeeper，散仙最近是最自动化安装脚本上迷了，咱们也不会复杂的，先从简单的开始联手，下面进入正题：
安装条件：
1，确保你的JAVA环境是OK的，JDK什么的
2，在root根目录下有一个zookeeper下好的压缩包
3，安装脚本默认放在root目录下
4，所有的安装目录，及压缩包命名，都在本脚本的前面几行定义，散仙为了方便写的比较固定，需要灵活的朋友们，可以做成动态的路径
5，确认上面的4步是ok的，下面就可以运行这个脚本了
6，安装完成后会在最后的状态里面打印出zk的运行情况
下面看散仙的安装日志：
注意散仙的是单机安装，如果想要分布式安装也是非常简单的，用for循环加上ssh，远程执行，再对myid和zoo.cfg稍作配置即可。
散仙上面运行的是多次，运行的，大于第一次运行的，会在后面检测如果已经有zk的进程，会杀死，重启，单机版本，zk成功的标志就是显示状态为standalone
脚本如下：

脚本如下：

ipath=/root/izk
ipaddress="192.168.46.21"
if [ ! -e $ipath ] ; then
echo "路径不存在,创建安装路径!"

else
rm -rf $ipath"/"*
echo "路径存在，已清空完毕！"
fi
echo "解压zk到指定目录下!"
sleep 2
tar -zxvf $zkpath -C $ipath
echo "解压完毕！"
cd $ipath
mv zookeeper-3.4.5 zookeeper
confpath=$ipath"/zookeeper"
cd $confpath
mkdir data
cd data
echo "1" >> myid
echo "生成myid文件......."
cd $confpath"/conf"
mv zoo_sample.cfg zoo.cfg

echo "dataDir=$confpath/data" >> zoo.cfg
echo "server.1=$ipaddress:2887:3887" >> zoo.cfg
echo "写入zoo.cfg文件成功!"
sleep 3
pid=`ps -ef | grep zookeeper | gawk '{ print $2}' | head -n 1`
echo "zk进程号: $pid"
sleep 2
#检查进程号是否为空
if [ ! -z $pid ] ; then
kill -9 $pid
echo "检测到zookeeper进程存在，已关闭!"
fi
echo "开始启动zk....."
cd ..
bin/zkServer.sh start
echo "启动完成....查看zookeeper状态"
bin/zkServer.sh status
