linux下 安装zookeeper，设置开机自启动

话不多说，直接上步骤

1、下载安装包

cd /usr/local wget https://mirrors.tuna.tsinghua.edu.cn/apache/zookeeper/zookeeper-3.6.1/apache-zookeeper-3.6.1-bin.tar.gz 这是清华大学的开源软件镜像网站，如果3.6.1的镜像不在了，直接去这个网站看看别的镜像，换个镜像下载

2、解压安装包

tar -zxvf apache-zookeeper-3.6.1-bin.tar.gz

3、进去，修改配置文件

执行 cp zoo_sample.cfg zoo.cfg

修改zoo.cfg

# The number of milliseconds of each tick # zookeeper 定义的基准时间间隔，单位：毫秒 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=/tmp/zookeeper # 数据文件夹 dataDir=/tmp/zookeeper/data # 日志文件夹 dataLogDir=/tmp/zookeeper/log # the port at which the clients will connect # 客户端访问 zookeeper 的端口号 clientPort=2181 # the maximum number of client connections. # increase this if you need to handle more clients #maxClientCnxns=60 #自定义启动端口，防止冲突 admin.serverPort=8888 # # 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

dataDir=/tmp/zookeeper/data dataLogDir=/tmp/zookeeper/log 这2个目录需要手动去创建

mkdir /tmp/zookeeper/data

mkdir /tmp/zookeeper/log

4、测试启动

到bin 目录下，启动程序。

5、设置服务器开机自启动

执行 cd /etc/rc.d/init.d/ vi zookeeper 在文件中输入，注意不要复制少了 #chkconfig:2345 20 90 #description:zookeeper #processname:zookeeper #jdk的路径，根据服务器情况自己修改 export JAVA_HOME=/usr/java/jdk1.8.0_231 #zk路径，根据情况修改 case $1 in start) su root /usr/local/apache-zookeeper-3.6.1-bin/bin/zkServer.sh start;; stop) su root /usr/local/apache-zookeeper-3.6.1-bin/bin/zkServer.sh stop;; status) su root /usr/local/apache-zookeeper-3.6.1-bin/bin/zkServer.sh status;; restart) su root /usr/local/apache-zookeeper-3.6.1-bin/bin/zkServer.sh restart;; *) echo "require start|stop|status|restart" ;; esac

设置执行权限 

chmod 777 zookeeper

添加到启动项

chkconfig --add zookeeper

查看状态

chkconfig --list zookeeper

测试一下脚本

service zookeeper start service zookeeper stop service zookeeper restart service zookeeper status
