详细说明：ZooKeeper集群搭建手动清理日志 /usr/lib/zookeeper/bin/zkCleanup sh dataLog Dir [snapDir]-n count DEE: /usr/lib/zookeeper/bin/zk Cleanup. sh/var/lib/zookeeper//var/lib/zookeeper/5 AB: /usr/lib/zookeeper/bin/zkCleanup. sh/data/disk01/zookeeper/zk_log/ /data/disko 1/zookeeperzk_data/5 自动清理见配置优化 ZooKeeper优化配置 ZooKeeper参数配置 http://my.oschina.net/w/128568/blog/194820 ZooKeeper自动清理日志 autopurge. purgeInterva这个参数指定了清理频率,单位是小时,需要填写一个1或更大的整数, 默认是0,表示不开启自己清理功能。 autopurge, snapRetain Count这个参数和上面的参数搭配使用,这个参数指定了需要保留的文件数目。默认是保留3个。 Zookeeper常见管理和运维 http://nileader.blog.51cto.com/1381108/1032157 ZooKeeper测试 https:/github.com/phunt/zk-smoketest zk-smoketest 运行原理 1. create a root znode for the test, i. e.zk-smoketest 2.attach a zk session to each server in the ensemble (the -servers list) 3.each client will create ephemeral nodes and attach watches on nodes of the other clients 4.each client will then delete the the ephemeral znodes it owns, all clients verify watches are triggered properly 5. client then cleans up, removing /zk-smoketest znode 用法 Usage: zk-smoketest py [options Options: - h,--help show this help message and exit --servers=SERVERs comma separated list of host: port (default localhost: 2181) --config= CONFIGFILE zookeeper configuration file to lookup servers from timeout=TIMEOUT session timeout in milliseconds(default 5000) -V,--verbose verbose output, include more detail q, --quiet quiet output, basically just success/failure 使用命令: PYTHONPATH=lib. linux-X86 64-2.6/ LD LIBRARY PATH=lib. linux-x86 64-2.6/.zk- smoketest. py --servers="bigdata 101: 2181, bigdata 102: 2181, bigdata103: 2181-V zk-latencies 运行原理 This tool uses the ZooKeeper python binding to test various operation latencies. 1. create a root znode for the test, i.e/zk-latencies 2. attach a zk session to each server in the ensemble(the -servers list) 3. run various(create/get/set/delete) operations against each server, note the latencies of operations 4. client then cleans up, removing /zk-latencies znode By default asynchronous operations are run specify the -synchronous"flag if you want synchronous operations to be used. Typically the difference between the two will give you insight into your network latency 用法 Usage: Zk-latencies py [options] Options -h,--help show this help message and exit --servers-SERVERs comma separated list of host: port(default localhost: 2181) -cluster=CLUSTER comma separated list of host: port, test as a cluster alternative to --servers --config=CONFIG FILE zookeeper configuration file to lookup servers from timeout=TIMEOUT session timeout in milliseconds(default 5000) -root znode=ROOT ZNODE root for the test, will be created as part of test (default/zk-latencies) -znode size=ZNODE SIZE data size when creating/setting nodes(default 25) znode count=ZNODE COUNT the number of nodes to operate on in each performance section (default 10000) watch_multiple=WATCH_MULTIPLE number of watches to put on each znode(default 1) -force force the test to run even if root znode exists WARNING! don't run this on a real znode or you'll lose it!!! --synchronous by default asynchronous ZK api is used, this forces synchronous calls -V,--verbose verbose output, include more detail q, --quiet quiet output, basically just success/failure 使用示例 PYTHONPATH=lib. linux-X86 64-2.6/LD LIBRARY PATH=lib. linux-X86 64-2.6//zk latencies. py --servers="bigdata101: 2181, bigdata102: 2181, bigdata103: 2181 znode size=100--znode_count=101--watch_multiple=102 创建101个 znode,每个 znode的数据大小为100,每个 znode有102个 watch
