1. 各节点做准备工作
安装python和java
[root@sht-sgmhadoopcm-01 ~]# tar -zxf Python-2.7.15.tgz [root@sht-sgmhadoopcm-01 ~]# cd Python-2.7.15 [root@sht-sgmhadoopcm-01 Python-2.7.15]# ./configure --prefix=/usr/local/python-2.7.15 --enable-optimizations [root@sht-sgmhadoopcm-01 Python-2.7.15]# make && make install [root@sht-sgmhadoopcm-01 ~]# /usr/local/python-2.7.15/bin/python --version Python 2.7.15 [root@sht-sgmhadoopcm-01 ~]# tar -zxf jdk-8u111-linux-x64.tar.gz -C /usr/java/ [root@sht-sgmhadoopcm-01 ~]# /usr/java/jdk1.8.0_111/bin/java -version java version "1.8.0_111" Java(TM) SE Runtime Environment (build 1.8.0_111-b14) Java HotSpot(TM) 64-Bit Server VM (build 25.111-b14, mixed mode)
配置系统用户
[root@sht-sgmhadoopcm-01 ~]# groupadd -r -g 601 dba [root@sht-sgmhadoopcm-01 ~]# useradd -r -u 601 -d /home/cassandra -g dba -G root cassandra [root@sht-sgmhadoopcm-01 ~]# cat /home/cassandra/.bash_profile # .bash_profile # Get the aliases and functions if [ -f ~/.bashrc ]; then . ~/.bashrc fi # User specific environment and startup programs export CASSANDRA_HOME=/usr/local/cassandra export JAVA_HOME=/usr/java/jdk1.8.0_171 export PYTHON_HOME=/usr/local/python-2.7.15 export PATH=$PYTHON_HOME/bin:$JAVA_HOME/bin:$CASSANDRA_HOME/bin:$CASSANDRA_HOME/tools/bin:$PATH:$HOME/bin:/usr/local/bin
安装Cassandra
[root@sht-sgmhadoopcm-01 ~]# tar -zxf apache-cassandra-2.1.20-bin.tar.gz -C /usr/local/ [root@sht-sgmhadoopcm-01 ~]# ln -s /usr/local/apache-cassandra-2.1.20 /usr/local/cassandra [root@sht-sgmhadoopcm-01 ~]# chown -R cassandra.dba /usr/local/apache-cassandra-2.1.20/
2. 配置cassandra
cassandra-topology.properties文件各节点一致
[cassandra@sht-sgmhadoopcm-01 conf]$ cat cassandra-topology.properties
