3.2.安装 Python
注意：Cassandra的客户端的使用需要用的Python2.X版本。需要先安装Python2.X
[root@cassandra cassandra]# python -V Python 2.7.5- 1

3.3.下载文件
# 下载 4.0.1 # wget https://archive.apache.org/dist/cassandra/4.0.1/apache-cassandra-4.0.1-bin.tar.gz # 解压 # tar -zxvf apache-cassandra-4.0.1-bin.tar.gz [root@cassandra cassandra]# ll total 48248 drwxr-xr-x. 8 root root 176 Feb 28 19:09 apache-cassandra-4.0.1 -rw-r--r--. 1 root root 49404559 Feb 28 19:08 apache-cassandra-4.0.1-bin.tar.gz # 移动文件 [root@cassandra cassandra]# mv apache-cassandra-4.0.1 /usr/local/ [root@cassandra apache-cassandra-4.0.1]# ll total 600 drwxr-xr-x. 2 root root 230 Feb 28 19:09 bin -rw-r--r--. 1 root root 4832 Aug 30 2021 CASSANDRA-14092.txt -rw-r--r--. 1 root root 434601 Aug 30 2021 CHANGES.txt drwxr-xr-x. 3 root root 4096 Feb 28 19:09 conf drwxr-xr-x. 3 root root 33 Feb 28 19:09 doc drwxr-xr-x. 3 root root 4096 Feb 28 19:09 lib -rw-r--r--. 1 root root 12960 Aug 30 2021 LICENSE.txt -rw-r--r--. 1 root root 135759 Aug 30 2021 NEWS.txt -rw-r--r--. 1 root root 349 Aug 30 2021 NOTICE.txt drwxr-xr-x. 3 root root 230 Feb 28 19:09 pylib drwxr-xr-x. 4 root root 169 Feb 28 19:09 tools- 1

二、安装部署
1.配置 Cassandra
1.进入解压后的目录，创建3个 Cassandra 的数据文件夹
[root@cassandra apache-cassandra-4.0.1]# mkdir data [root@cassandra apache-cassandra-4.0.1]# mkdir commitlog [root@cassandra apache-cassandra-4.0.1]# mkdir saved-caches- 1
- 2
- 3
[root@cassandra apache-cassandra-4.0.1]# pwd /usr/local/apache-cassandra-4.0.1 [root@cassandra apache-cassandra-4.0.1]# mkdir data [root@cassandra apache-cassandra-4.0.1]# mkdir commitlog [root@cassandra apache-cassandra-4.0.1]# mkdir saved-caches- 1
- 2
- 3

- 5
2.修改配置文件
在 conf 目录中找到 cassandra.yaml 配置文件，配置上面创建的3个数据目录
- 配置 data_file_directories
data_file_directories: - /usr/local/apache-cassandra-4.0.1/data- 1
- 2
- 配置 commitlog_directory
commitlog_directory: /usr/local/apache-cassandra-4.0.1/commitlog- 1
- 配置 saved_caches_directory
saved_caches_directory: /usr/local/apache-cassandra-4.0.1/saved_caches- 1
- 配置 RPC
rpc_address: 192.168.202.156- 1
2.启动 Cassandra
# cd /usr/local/apache-cassandra-4.0.1/bin # ./cassandra -R- 1
- 2
- 3
[root@cassandra /]# cd /usr/local/apache-cassandra-4.0.1/bin [root@cassandra bin]# ll total 152 -rwxr-xr-x. 1 root root 10542 Aug 30 2021 cassandra -rw-r--r--. 1 root root 5667 Aug 30 2021 cassandra.in.sh -rwxr-xr-x. 1 root root 2995 Aug 30 2021 cqlsh -rwxr-xr-x. 1 root root 95408 Aug 30 2021 cqlsh.py -rwxr-xr-x. 1 root root 1894 Aug 30 2021 debug-cql -rwxr-xr-x. 1 root root 3491 Aug 30 2021 nodetool -rwxr-xr-x. 1 root root 1770 Aug 30 2021 sstableloader -rwxr-xr-x. 1 root root 1778 Aug 30 2021 sstablescrub -rwxr-xr-x. 1 root root 1778 Aug 30 2021 sstableupgrade -rwxr-xr-x. 1 root root 1781 Aug 30 2021 sstableutil -rwxr-xr-x. 1 root root 1778 Aug 30 2021 sstableverify -rwxr-xr-x. 1 root root 1175 Aug 30 2021 stop-server- 1

[root@cassandra bin]# ./cassandra -R [root@cassandra bin]# OpenJDK 64-Bit Server VM warning: Option UseConcMarkSweepGC was deprecated in version 9.0 and will likely be removed in a future release.

输入命令来查看正在运行的cassandra的 pid
ps -ef|grep cassandra- 1
显示如图，pid 是 1818：
3.关闭Cassandra
刚才已经查到了 pid，现在可以使用命令杀掉这个pid对应的进程
kill -9 1818- 1
4.查看状态
运行bin 目录下的 nodetool
[root@localhost bin]# ./nodetool status # nodetool -Dcom.sun.jndi.rmiURLParsing=legacy status # ./nodetool -h ::FFFF:127.0.0.1 status- 1

如果cassandra启动出错，可以在bin目录下 使用 journalctl -u cassandra 命令查看
[root@localhost bin]# journalctl -u cassandra- 1
# 问题 [root@cassandra bin]# ./nodetool status nodetool: Failed to connect to '127.0.0.1:7199' - URISyntaxException: 'Malformed IPv6 address at index 7: rmi://[127.0.0.1]:7199'. # 解决办法 [root@cassandra bin]# ./nodetool -Dcom.sun.jndi.rmiURLParsing=legacy status [root@cassandra bin]# ./nodetool -h ::FFFF:127.0.0.1 status- 1

5.客户端连接服务器
进入Cassandra的 bin 目录，输入
./cqlsh 192.168.202.156 9042 [root@cassandra bin]# ./cqlsh 192.168.202.156 9042 Python 2.7 support is deprecated. Install Python 3.6+ or set CQLSH_NO_WARN_PY2 to suppress this message. Connected to Test Cluster at 192.168.202.156:9042 [cqlsh 6.0.0 | Cassandra 4.0.1 | CQL spec 3.4.5 | Native protocol v5] Use HELP for help. cqlsh>- 1

6.服务运行脚本
为了方便管理，可以编写脚本来管理，在 /usr/local/apache-cassandra-4.0.1 下创建一个 startme.sh，输入一下内容：
#!/bin/sh CASSANDRA_DIR="/usr/local/apache-cassandra-4.0.1" echo "************cassandra***************" case "$1" in start) echo "* *" echo "* starting *" nohup $CASSANDRA_DIR/bin/cassandra -R >> $CASSANDRA_DIR/logs/system.log 2>&1 & echo "* started *" echo "* *" echo "************************************" ;; stop) echo "* *" echo "* stopping *" PID_COUNT=`ps aux |grep CassandraDaemon |grep -v grep | wc -l` PID=`ps aux |grep CassandraDaemon |grep -v grep | awk {'print $2'}` if [ $PID_COUNT -gt 0 ];then echo "* try stop *" kill -9 $PID echo "* kill SUCCESS! *" else echo "* there is no ! *" echo "* *" echo "************************************" fi ;; restart) echo "* *" echo "********* restarting ******" $0 stop $0 start echo "* *" echo "************************************" ;; status) $CASSANDRA_DIR/bin/nodetool status ;; *) echo "Usage:$0 {start|stop|restart|status}" exit 1 esac- 1

[root@cassandra apache-cassandra-4.0.1]# ./startme.sh start [root@cassandra apache-cassandra-4.0.1]# ./startme.sh restart [root@cassandra apache-cassandra-4.0.1]# ./startme.sh stop- 1
