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：
<pre name="code" class="shell">

zkpath=/root/zookeeper-3.4.5.tar.gz
ipath=/root/izk
ipaddress="192.168.46.21"

if  [ ! -e $ipath  ] ; then

echo "路径不存在,创建安装路径!"

mkdir  $ipath
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 "tikcTime=2000" >> 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
</pre>
