設定和啟動 Zookeeper 節點
如果已在 Solaris 平台上安裝 Index Search 伺服器，請執行下列步驟：
1. 建立每個 Zookeeper 節點的資料目錄。例如：
/opt/ptc/commondata/zkdata/node1
/opt/ptc/commondata/zkdata/node2
/opt/ptc/commondata/zkdata/node3
2. 建立名為 "myid" 的檔案來識別 Zookeeper 節點。檔案的目錄應該識別節點。
例如，下列 myid 檔案的目錄可以僅通過編號 1 表示：
/opt/ptc/commondata/zkdata/node1/myid
同樣地，輸入 2 可以導覽到 node2/myid，輸入 3 可以導覽到 node3/myid。
 |
這些是指派給 Zookeeper 的 ID，將用於下一步中的 zoo.cfg。
|
3. 建立 Zookeeper 組態檔案︰
<INDEX_SEARCH_HOME>\zookeeper\conf\zoo.cfg
其中 <INDEX_SEARCH_HOME> 是安裝索引搜尋伺服器的安裝目錄。
針對 node1 新增下列內容：
# 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=D:\\ptc\\commondata\\zkdata\\node1 OR /opt/ptc/commondata/zkdata/node1
# the port at which the clients will connect
clientPort=<埠號>
server.1=<主機1>.ptcnet.ptc.com:2888:3888
server.2=<主機2>.ptcnet.ptc.com:2889:3889
server.3=<主機3>.ptcnet.ptc.com:2890:3890
# the maximum number of client connections.
# increase this if you need to handle more clients
#maxClientCnxns=60
#
# 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
tickTime=2000
# The number of ticks that the initial
# 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.

server.1=<主機1>.ptcnet.ptc.com:2888:3888
server.2=<主機2>.ptcnet.ptc.com:2889:3889
server.3=<主機3>.ptcnet.ptc.com:2890:3890
# the maximum number of client connections.
# increase this if you need to handle more clients
#maxClientCnxns=60
#
# Be sure to read the maintenance section of the

# http://zookeeper.apache.org/doc/current/zookeeperAdmin.html#sc_maintenance

下列內容應該具唯一性，而且針對每個 Zookeeper 管理員節點指定︰
|
dataDir
|
Zookeeper 節點的資料目錄。
|
|
clientPort
|
Zookeeper 接聽請求的埠。
|
4. 執行下列指令，啟動所有 Zookeeper 節點︰
sh <INDEX_SEARCH_HOME>\zookeeper\bin\zkServer.sh start
|
|
啟動 Zookeeper 節點時，會開始與總體組態 (zoo.cfg) 中指定的其他 Zookeeper 節點進行通訊。
啟動時，您可能會看見主控台或記錄檔中的錯誤，報告節點無法連接至其他 Zookeeper 節點。這是因為這些節點尚未啟動。可以忽略這些錯誤。
