Thanks! I'll see to it. There're a lot to learn for CentOS, Geez. scott.chu，scott....@udngroup.com 2016/5/30 (週一) ----- Original Message ----- From: Shawn Heisey To: solr-user CC: Date: 2016/5/27 (週五) 15:13 Subject: Re: How to save index data to other place? [scottchu]

Installing Solr: https://cwiki.apache.org/confluence/display/solr/Taking+Solr+to+Production#TakingSolrtoProduction-RuntheSolrInstallationScript Zookeeper is a completely separate project from Solr. For best results, you should consult their documentation: http://zookeeper.apache.org/doc/r3.4.8/zookeeperAdmin.html I can give you some quick install steps based on what I have done in the past. I have no idea whether this is how the zookeeper project would recommend doing it, but if it's done correctly, I know that it works. Extract the download tarball into some location, like /opt. If you choose that location and extract the latest version, you will have /opt/zookeeper-3.4.8 to work with. The rest of this assumes that directory location. You may need to adjust these steps if you choose another location: Create a shell script named /usr/local/sbin/zkrun with these contents: -------------------------- #!/bin/sh # chkconfig: - 75 50 # description: Starts and stops Zookeeper cd /opt/zookeeper bin/zkServer.sh $1 -------------------------- Change to the /opt directory and do these commands: ln -s zookeeper-3.4.8 zookeeper chmod +x /usr/local/sbin/zkrun ln -s /usr/local/sbin/zkrun /etc/init.d/zookeeper chkconfig --add zookeeper chkconfig zookeeper on Consult zookeeper documentation on how to configure the newly installed server -- which consists of creating /opt/zookeeper/conf/zoo.cfg and ${dataDir}/myid A common setting for the dataDir config parameter is "zoodata". This is a path that is relative to the current working directory. If you use my little startup script with that value, the full path becomes opt/zookeeper/zoodata. Once it's configured, you can start the zookeeper service. This is a slightly redacted copy of my zookeeper config file: ------------------------------------- # The number of milliseconds of each tick 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=zoodata # the port at which the clients will connect clientPort=2181 # # 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 server.1=zoo1.REDACTED.com:2888:3888 server.2=zoo2.REDACTED.com:2888:3888 server.3=zoo3.REDACTED.com:2888:3888 ------------------------------------- Thanks, Shawn ----- 未在此訊息中找到病毒。 已透過 AVG 檢查 - www.avg.com 版本: 2015.0.6201 / 病毒庫: 4568/12324 - 發佈日期: 05/29/16
