1. 下載
-
或者去這里現(xiàn)在你需要的版本
root@debian:~/soft/bk# wget http://mirrors.hust.edu.cn/apache/zookeeper/stable/zookeeper-3.4.12.tar.gz
2. 安裝和配置
限于測試環(huán)境屠尊，只在單機(jī)上部署3個(gè)實(shí)例毅臊，生產(chǎn)環(huán)境需要所有實(shí)例分散在不同的機(jī)器上

創(chuàng)建配置文件

安裝
root@debian:~/soft/bk# mkdir -p /usr/local/zookeeper_cluster root@debian:~/soft/bk# cp -r zookeeper-3.4.12 /usr/local/zookeeper_cluster/z1 root@debian:~/soft/bk# cp -r zookeeper-3.4.12 /usr/local/zookeeper_cluster/z2 root@debian:~/soft/bk# cp -r zookeeper-3.4.12 /usr/local/zookeeper_cluster/z3z1, z2, z3 分別是三個(gè)實(shí)例
- 修改z2/conf/zoo.cfg, 修改dataDir和clientPort項(xiàng)
dataDir=/data/zookeeper/data/z2 # the port at which the clients will connect clientPort=2282 - 修改z3/conf/zoo.cfg, 修改dataDir和clientPort項(xiàng)
dataDir=/data/zookeeper/data/z3 # the port at which the clients will connect clientPort=2283
- 修改z2/conf/zoo.cfg, 修改dataDir和clientPort項(xiàng)

創(chuàng)建數(shù)據(jù)存儲(chǔ)目錄
root@debian:~/soft/bk/zookeeper-3.4.12# mkdir -p /data/zookeeper/data root@debian:~/soft/bk/zookeeper-3.4.12# cd /data/zookeeper/data/ root@debian:/data/zookeeper/data# mkdir z1 z2 z3 -
創(chuàng)建myid, id與zoo.cfg中server.X的x對應(yīng)
root@debian:/data/zookeeper/data# echo 1 > z1/myid root@debian:/data/zookeeper/data# echo 2 > z2/myid root@debian:/data/zookeeper/data# echo 3 > z3/myid
3. 啟動(dòng)和測試
- 創(chuàng)建一個(gè)啟動(dòng)三個(gè)實(shí)例的sh, start.sh
./z1/bin/zkServer.sh start & ./z2/bin/zkServer.sh start & ./z3/bin/zkServer.sh start & - 測試
一些操作命令root@debian:/usr/local/zookeeper_cluster/z1/bin# ./zkCli.sh -server 127.0.0.1:2281[zk: 127.0.0.1:2281(CONNECTED) 2] create /zk_test hello Created /zk_test [zk: 127.0.0.1:2281(CONNECTED) 3] get /zk_test hello cZxid = 0x100000003 ctime = Wed Sep 19 18:04:00 CST 2018 mZxid = 0x100000003 mtime = Wed Sep 19 18:04:00 CST 2018 pZxid = 0x100000003 cversion = 0 dataVersion = 0 aclVersion = 0 ephemeralOwner = 0x0 dataLength = 5 numChildren = 0 [zk: 127.0.0.1:2281(CONNECTED) 4] set /zk_test fuck cZxid = 0x100000007 ctime = Wed Sep 19 18:09:32 CST 2018 mZxid = 0x100000008 mtime = Wed Sep 19 18:09:40 CST 2018 pZxid = 0x100000007 cversion = 0 dataVersion = 1 aclVersion = 0 ephemeralOwner = 0x0 dataLength = 4 numChildren = 0 [zk: 127.0.0.1:2281(CONNECTED) 5] get /zk_test fuck cZxid = 0x100000007 ctime = Wed Sep 19 18:09:32 CST 2018 mZxid = 0x100000008 mtime = Wed Sep 19 18:09:40 CST 2018 pZxid = 0x100000007 cversion = 0 dataVersion = 1 aclVersion = 0 ephemeralOwner = 0x0 dataLength = 4 numChildren = 0 [zk: 127.0.0.1:2281(CONNECTED) 6] delete /zk_test [zk: 127.0.0.1:2281(CONNECTED) 7] ls / [zookeeper] [zk: 127.0.0.1:2281(CONNECTED) 8]
