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
