ZooKeeper
installation
#将ZooKeeper解压到/usr/local.
TAR–ZXVF zookeeper-3.4.6.tar.gz–c/usr/local
Cd/usr/local
#重命名
sudo mv zookeeper-3.4.6 zookeeper
CD zookeeper/conf
sudo cp zoo_sample.cfg zoo.cfg
Configuration
1. Append the following to the ZOO.CFG:
#server. N=IP:PORTA:PORTB
#n是服务器标识号 (1~255)
#ip是服务器ip地址
#portA是与leader进行信息交换的端口
#portB是在leader宕机后, the ports used for leader elections
server.1=200.31.157.116:20881:30881
server.2=200.31.157.116:20882:30882
server.3=200.31.157.117:20881:30881
Note:
Configuration file Information parsing:
Ticktime: The basic unit of time in milliseconds, and other times such as heartbeat/timeout are integer multiples of the unit time.
A multiple of initlimit:ticktime, indicating that the time required for followers to synchronize with leader after the leader election, leader data is very large or followers relatively long, the value should be more appropriate.
A multiple of synclimit:ticktime that represents the maximum wait time for follower and observer to interact with leader, which is the time-out when a normal request forward or ping message interacts with the leader after synchronization is complete.
ClientPort: Listen for the service port of the client connection, if you have multiple zookeeper servers installed on one server, you need to set a different port number.
DataDir: Memory Database snapshot address, transaction log address (unless otherwise specified by Datalogdir).
2. Create a new file myID under $datadir and write to the server identification number
#/tmp/zookeeper to DataDir
cd/tmp/zookeeper/
sudo vim myID
#在myid中添加服务器标识号
Start Stop
#进入 $ZOOKEEPER _home, run zkserver.sh
#启动
sudo bin/zkserver.sh start &
#停止
sudo bin/zkserver.sh stop
#查看状态
sudo bin/zkserver.sh status
