zookeeper 集群安装和配置

Posted 2020-10-15

一、单机模式

1、解压安装

mv zookeeper-3.4.6.tar.gz /wls/  &&  tar zxvf zookeeper-3.4.6.tar.gz 

cd /wls/zookeeper-3.4.6/conf && mv zoo_sample.cfg zoo.cfg 

2、单机启动

cd /wls/zookeeper-3.4.6/bin/ && zkServer.sh  start

3、登陆zk

cd /wls/zookeeper-3.4.6/bin/ && ./zkCli.sh

二、集群模式

1、修改配置文件

cd /wls/zookeeper-3.4.6/conf && mv zoo.cfg  z1.cfg

修改节点1 z1 配置文件

initLimit=10

syncLimit=5

clientPort=2187

tickTime=20000

maxClientCnxns=2000

minSessionTimeout=50000

maxSessionTimeout=90000

autopurge.purgeInterval=24

autopurge.snapRetainCount=5

dataDir=/wls/zookeeper-3.4.6/servers/z1/data

zoologdir=/wls/zookeeper-3.4.6/servers/z1/log

dataLogDir=/wls/zookeeper-3.4.6/servers/z1/datalog

server.1=30.4.92.49:8887:9887

server.2=30.4.92.49:8888:9888

server.3=30.4.92.49:8889:9889

修改节点2 z2 配置文件

initLimit=10

syncLimit=5

clientPort=2188

tickTime=20000

maxClientCnxns=2000

minSessionTimeout=50000

maxSessionTimeout=90000

autopurge.purgeInterval=24

autopurge.snapRetainCount=5

dataDir=/wls/zookeeper-3.4.6/servers/z2/data

zoologdir=/wls/zookeeper-3.4.6/servers/z2/log

dataLogDir=/wls/zookeeper-3.4.6/servers/z2/datalog

server.1=30.4.92.49:8887:9887

server.2=30.4.92.49:8888:9888

server.3=30.4.92.49:8889:9889

修改节点3 z3 配置文件

initLimit=10

syncLimit=5

clientPort=2189

tickTime=20000

maxClientCnxns=2000

minSessionTimeout=50000

maxSessionTimeout=90000

autopurge.purgeInterval=24

autopurge.snapRetainCount=5

dataDir=/wls/zookeeper-3.4.6/servers/z3/data

zoologdir=/wls/zookeeper-3.4.6/servers/z3/log

dataLogDir=/wls/zookeeper-3.4.6/servers/z3/datalog

server.1=30.4.92.49:8887:9887

server.2=30.4.92.49:8888:9888

server.3=30.4.92.49:8889:9889

2、修改日志路径 

调整之后日志路径为 Dzookeeper.log.dir=/wls/zookeeper-3.4.6/servers/z1/log

vim /wls/zookeeper-3.4.6/bin/zkServer.sh ,ZOO_DATADIR后面新增一行ZOO_LOG_DIR

if [ -z "$ZOOPIDFILE" ]; then

    ZOO_DATADIR="$(grep "^[[:space:]]*dataDir" "$ZOOCFG" | sed -e ‘s/.*=//‘)"

    ZOO_LOG_DIR="$(grep "^[[:space:]]*zoologdir" "$ZOOCFG" | sed -e ‘s/.*=//‘)"

修改/wls/zookeeper-3.4.6/bin/zkEvn.sh文件,这样zookeeper.log文件就会独立，而不是和zookeeper.out一起

if [ "x${ZOO_LOG4J_PROP}" = "x" ]

then

    ZOO_LOG4J_PROP="INFO,CONSOLE"

fi

改成 

if [ "x${ZOO_LOG4J_PROP}" = "x" ]

then

    ZOO_LOG4J_PROP="INFO,ROLLINGFILE"

fi

  

  

3、创建数据和日志目录

z1节点

mkdir -p /wls/zookeeper-3.4.6/servers/z1/data

mkdir -p /wls/zookeeper-3.4.6/servers/z1/log

mkdir -p /wls/zookeeper-3.4.6/servers/z1/datalog

echo 1 > /wls/zookeeper-3.4.6/servers/z1/data/myid

z2节点

mkdir -p /wls/zookeeper-3.4.6/servers/z2/data

mkdir -p /wls/zookeeper-3.4.6/servers/z2/log

mkdir -p /wls/zookeeper-3.4.6/servers/z2/datalog

echo 2 > /wls/zookeeper-3.4.6/servers/z2/data/myid

z3节点

mkdir -p /wls/zookeeper-3.4.6/servers/z3/data

mkdir -p /wls/zookeeper-3.4.6/servers/z3/log

mkdir -p /wls/zookeeper-3.4.6/servers/z3/datalog

echo 3 > /wls/zookeeper-3.4.6/servers/z3/data/myid

4、修改jvm 参数

在zkServer.sh文件的49行处加入 JVMPARAM="-Xms1G -Xmx1G"

在zkServer.sh文件的112行修改 -cp "$CLASSPATH" $JVMFLAGS $JVMPARAM $ZOOMAIN "$ZOOCFG" > "$_ZOO_DAEMON_OUT" 2>&1 < /dev/null &

 

5、修改jmxremote参数

在zkServer.sh文件 修改 ZOOMAIN="-Dcom.sun.management.jmxremote -Dcom.sun.management.jmxremote.local.only=$JMXLOCALONLY org.apache.zookeeper.server.quorum.QuorumPeerMain" 为

ZOOMAIN=" -Dcom.sun.management.jmxremote.ssl=false org.apache.zookeeper.server.quorum.QuorumPeerMain"

6、修改最大数据量,zookeeper默认对每个结点的最大数据量有一个上限是1M,如果你要设置的配置数据大于这个上限将无法写法，增加-Djute.maxbuffer=10240000参数 

在zkEnv.sh文件最后添加一行 -Djute.maxbuffer=10240000

7、启动服务

/wls/zookeeper-3.4.6/bin/zkServer.sh start ../conf/z1.cfg 

/wls/zookeeper-3.4.6/bin/zkServer.sh start ../conf/z2.cfg

/wls/zookeeper-3.4.6/bin/zkServer.sh start ../conf/z3.cfg

8、查看状态 

/wls/zookeeper-3.4.6/bin/zkServer.sh status  ../conf/z1.cfg

9、关闭服务

/wls/zookeeper-3.4.6/bin/zkServer.sh stop ../conf/z1.cfg 

/wls/zookeeper-3.4.6/bin/zkServer.sh stop ../conf/z2.cfg

/wls/zookeeper-3.4.6/bin/zkServer.sh stop ../conf/z3.cfg
