7下ZooKeeper 集群安装部署
安装JDK
yum install -y java-1.8.0-openjdk安装ZooKeeper
下载
wget http://mirror.bit.edu.cn/apache/zookeeper/zookeeper-3.4.10/zookeeper-3.4.10.tar.gz
tar -zxvf zookeeper-3.4.10.tar.gz
官方地址：http://www.apache.org/dyn/closer.cgi/zookeeper/配置zoo.cfg
cp conf/zoo_sample.cfg conf/zoo.cfg
vi conf/zoo.cfg修改(本)
# the directory where the snapshot is stored.
# do not use /tmp for storage, /tmp here is just
# example sakes.
dataDir=/data/solr/zookeeper
# the port at which the clients will connect
clientPort=2181
server.211=dt211.corp:2888:3888
server.212=0.0.0.0:2888:3888
server.214=dt214.corp:2888:3888创建数据目录和myid
mkdir /data/solr/zookeeper
vi /data/solr/zookeeper/myidmyid 文件中只有一个数字，与server id对应
212防火墙配置
firewall-cmd --permanent --add-port=2181/tcp
firewall-cmd --permanent --add-port=2888/tcp
firewall-cmd --permanent --add-port=3888/tcp
firewall-cmd --reload同步到其它机器
--------------------------------------分割线 --------------------------------------
CentOS7 NFS共享设置
安装nfs工具
yum install -y nfs-utils配置共享目录
创建共享目录
mkdir /home/share目录授权
chmod 766 /home/share编辑exports
vi /etc/exports添加内容
/home/share 192.168.1.0/24(rw,sync)先启动rpcbind
systemctl start rpcbind在启动nfs
systemctl start nfs查看本机共享目录
exportfs防火墙设置
firewall-cmd --permanent --add-service=nfs
firewall-cmd --reload挂载共享目录
安装nfs，同上
创建挂载目录
mkdir /mnt/share添加挂载
mount 192.168.1.212:/home/share /mnt/share异常处理
1.mount.nfs: requested NFS version or transport protocol is not supported
启动顺序不对，先启动rpcbind，在启动nfs
2.mount.nfs: access denied by server while mounting
--------------------------------------分割线 --------------------------------------
修改zoo.cfg，本机IP地址：0.0.0.0
启动集群
启动
bin/zkServer.sh start查看状态
bin/zkServer.sh status停止
bin/zkServer.sh stop异常处理
1.java.net.ConnectException: 拒绝连接 (Connection refused)
本机IP要改成0.0.0.0，无法识别别名，127.0.0.1也只能有一台
CentOS7下Solr6.6 集群安装部署
Solr
添加zk地址
vi bin/solr.in.sh# Set the ZooKeeper connection string if using an external ZooKeeper ensemble
# e.g. host1:2181,host2:2181/chroot
# Leave empty if not using SolrCloud
ZK_HOST="hbase201:2181,hbase202:2181,hbase203:2181/solr"
# Set the ZooKeeper client timeout (for SolrCloud mode)
ZK_CLIENT_TIMEOUT="15000"上传配置文件
./zkcli.sh -zkhost hbase201,hbase202,hbase203:2181/solr -cmd upconfig -confdir /usr/solr/solr-6.6.0/server/solr/configsets/data_driven_schema_configs/conf -confname solr同步到其它服务器
scp -r /usr/solr hbase201:/usr/
scp -r /usr/solr hbase202:/usr/分别启动solr服务
bin/solr start -force集群操作
查看状态
http://hbase203:8983/solr/#/~cloud创建集群
http://hbase203:8983/solr/admin/collections?action=CREATE&name=test&numShards=3&replicationFactor=3&maxShardsPerNode=3&collection.configName=solr删除集群
http://hbase203:8983/solr/admin/collections?action=DELETE&name=test重新加载
http://hbase203:8983/solr/admin/collections?action=RELOAD&name=test更新配置文件，添加DIH
修改solrconfig.xml
vi solrconfig.xml<lib dir="${solr.install.dir:../../../..}/dist/" regex="solr-dataimporthandler-.*\.jar" />
<requestHandler name="/dataimport" class="solr.DataImportHandler">
<lst name="defaults">

备份
http://hbase201:8983/solr/test/replication?command=backup&location=/home/test_bak恢复
- 停止Solr服务
- Copy备份文件到CoreIndex目录
- 启动Solr服务
Index存储为HDFS
