zookeeper事务日志在哪儿

Posted 2023-04-01

参考技术A 前期准备1.修改Linux主机名，每台都得配置vim /etc/sysconfig/networkNETWORKING=yesHOSTNAME=hadoop-server12.修改IP /etc/sysconfig/network-scripts/ifcfg-eth03.修改主机名和IP的映射关系vim /etc/hosts192.168.146.181 hadoop-server1192.168.146.182 hadoop-server2192.168.146.183 hadoop-server3192.168.146.184 hadoop-server4192.168.146.185 hadoop-server5######注意######如果你们公司是租用的服务器或是使用的云主机（如华为用主机、阿里云主机等）/etc/hosts里面要配置的是内网IP地址和主机名的映射关系4.关闭防火墙 #查看防火墙状态service iptables status#关闭防火墙service iptables stop#查看防火墙开机启动状态chkconfig iptables --list#关闭防火墙开机启动chkconfig iptables off前4步用root用户操作，操作完后重启机器5.ssh免登陆hadoop用户操作#生成ssh免登陆密钥#进入到我的home目录cd ~/.sshssh-keygen -t rsa （四个回车）执行完这个命令后，会生成两个文件id_rsa（私钥）、id_rsa.pub（公钥）将公钥拷贝到要免密登陆的目标机器上ssh-copy-id hadoop-server26.安装JDK，配置环境变量等root用户操作vim /etc/proflieexport JAVA_HOME=/usr/java/jdk1.7.0_65export HADOOP_HOME=/itcast/hadoop-2.4.1export PATH=$PATH:$JAVA_HOME/bin:$HADOOP_HOME/bin:$HADOOP_HOME/sbinsource /etc/profile集群规划：主机名 IP 安装软件 运行进程hadoop-server1 192.168.146.181:jdk、hadoopnamenode resourcemanageDFSZKFailoverController(zkfc)hadoop-server2 192.168.146.182:jdk、hadoopnamenode resourcemanageDFSZKFailoverController(zkfc)hadoop-server3 192.168.146.183:jdk、hadoop、zookeeperdatanode nodemanagejournalnode QuorumPeerMainhadoop-server4 192.168.146.184:jdk、hadoop、zookeeperdatanode nodemanagejournalnode QuorumPeerMainhadoop-server5 192.168.146.185:jdk、hadoop、zookeeperdatanode nodemanagejournalnode QuorumPeerMain安装步骤：1.安装配置zooekeeper集群（在hadoop-server3上）1.1解压tar -zxvf zookeeper-3.4.5.tar.gz -C /home/hadoop/app/1.2修改配置cd /home/hadoop/app/zookeeper-3.4.5/conf/cp zoo_sample.cfg zoo.cfgvim zoo.cfg修改：dataDir=/home/hadoop/app/zookeeper-3.4.5/data在最后添加：server.1=hadoop-server3:2888:3888server.2=hadoop-server4:2888:3888server.3=hadoop-server5:2888:3888保存退出然后创建一个tmp文件夹mkdir /home/hadoop/app/zookeeper-3.4.5/data再创建一个空文件touch /home/hadoop/app/zookeeper-3.4.5/data/myid最后向该文件写入IDecho 1 > /home/hadoop/app/zookeeper-3.4.5/data/myid1.3将配置好的zookeeper拷贝到其他节点scp -r /home/hadoop/app/zookeeper-3.4.5/ weekend06:/home/hadoop/app/scp -r /home/hadoop/app/zookeeper-3.4.5/ weekend07:/home/hadoop/app/注意：修改hadoop-server4、hadoop-server5对应/home/hadoop/app/zookeeper-3.4.5/data/myid内容hadoop-server4：echo 2 > /home/hadoop/app/zookeeper-3.4.5/data/myidhadoop-server5：echo 3 > /home/hadoop/app/zookeeper-3.4.5/data/myid2.安装配置hadoop集群（在hadoop-server1上操作）2.1解压tar -zxvf hadoop-2.4.1.tar.gz -C /weekend/2.2配置HDFS（hadoop2.0所有的配置文件都在$HADOOP_HOME/etc/hadoop目录下）#将hadoop添加到环境变量中vim /etc/profileexport JAVA_HOME=/hadoop/home/app/jdk1.7.0_55export HADOOP_HOME=/home/hadoop/app/hadoop-2.4.1export PATH=$PATH:$JAVA_HOME/bin:$HADOOP_HOME/bin#hadoop2.0的配置文件全部在$HADOOP_HOME/etc/hadoop下cd /home/hadoop/app/hadoop-2.4.1/etc/hadoop2.2.1修改hadoo-env.shexport JAVA_HOME=/home/hadoop/app/jdk1.7.0_552.2.2修改core-site.xml<configuration><!-- 指定hdfs的nameservice为ns1
