zookeeper 安装配置启动

• • • 1. 安装
    • 2. 配置
    • 3. 启动zookeeper集群
    • 4. 查看启动情况

# 解压gz包
tar -zxvf apache-zookeeper-3.6.3-bin.tar.gz

1. 创建一个数据目录和日志目录

mkdir /root/data
mkdir /root/log

2. 在创建的数据目录下创建myid文件

touch /root/data/myid
ehoc 1 >> /root/data/myid # 每个节点的编号不一样

3. 复制zoo_sample.cfg文件

# 在zookeeper解压后的conf目录下
cp zoo_sample.cfg zoo.cfg

4. 增加集群节点信息

# server.1 这里的数字和之前创建的myid文件中写入的编号一致
quorumListenOnAllIPs=true
server.1=ip:2888:3888
server.2=ip:2888:3888
server.3=ip:2888:3888

5. 最终的配置文件

# synchronization phase can take

# 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.

dataLogDir=/root/log
# the port at which the clients will connect
