在同一台机器上运行两个cassandra版本 [英] run two cassandra versions in the same machine
本文介绍了在同一台机器上运行两个cassandra版本的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我有一个场景，在同一台机器上但是在不同的端口运行两个不同版本的cassandra。
我开始一个集群，在 cassandra config 9161 ，
＃TCP端口，用于命令和数据
storage_port：7000
＃SSL端口，用于加密通信。除非在
＃encryption_options
中启用，否则为
ssl_storage_port：7004
CQL本地传输端口，用于侦听
上的客户端native_transport_port：9043
Thrift在
上监听客户端rpc_port：9161
seed_provider：
＃被认为是联络点的主机地址。
＃Cassandra节点使用此主机列表来查找彼此并学习
＃环的拓扑。如果您正在运行
＃多个节点，则必须更改此值！
- class_name：org.apache.cassandra.locator.SimpleSeedProvider
parameters：
＃seeds实际上是一个以逗号分隔的地址列表。
＃Ex：< ip1>，< ip2>，< ip3>
- 种子：127.0.0.1
运行良好，
$ /usr/local/apache-cassandra-2.1.1/bin/cassandra -f
...
INFO 05:08:42从文件加载设置：/usr/local/apache-cassandra-2.1.1/conf/cassandra.yaml
...

INFO 05:09:29窃听客户端...
INFO 05:19:25没有要压缩用于用户定义压缩的文件
$ jps
5866 CassandraDaemon
8848 Jps
但是当启动另一个配置为在端口 9160 下运行的cassandra集群时，
＃TCP端口，用于命令和数据
storage_port：7000
＃SSL端口，用于加密通信。未使用，除非在
＃encryption_options
中启用
ssl_storage_port：7004
CQL本地传输端口用于侦听
上的客户端native_transport_port：9042
Thrift端口在
上监听客户端rpc_port：9160
seed_provider：
＃被认为是联络点的主机地址。
＃Cassandra节点使用此主机列表来查找彼此并学习
＃环的拓扑。如果您正在运行
＃多个节点，则必须更改此值！
- class_name：org.apache.cassandra.locator.SimpleSeedProvider
parameters：
＃seeds实际上是一个以逗号分隔的地址列表。
＃Ex：< ip1>，< ip2>，< ip3>
- 种子：127.0.0.1

$ b
$ /usr/local/apache-cassandra-2.0.11/bin/cassandra -f
无法绑定JMX，是Cassandra已经运行？如何在同一台机器上运行两个不同版本的cassandra？

问题是我没有权限停止以前的版本。我也不能使用 https://github.com/pcmanus/ccm
解决方案
我修改它改变几个配置 storage_port / ssl_storage_port 中的 conf / cassandra.yaml 和 cassandra-env.sh ，
conf / cassandra.yaml
＃TCP端口，用于命令和数据
storage_port：7004
＃SSL端口，用于加密通信。除非在
中启用，否则$ b $ encryption_options
ssl_storage_port：7005
CQL本地传输端口，用于侦听
上的客户端native_transport_port：9043
端口为Thrift听客户
rpc_port：9161
seed_provider：
＃被认为是联系点的主机的地址。
＃Cassandra节点使用此主机列表来查找彼此并学习
＃环的拓扑。如果您正在运行
＃多个节点，则必须更改此值！
- class_name：org.apache.cassandra.locator.SimpleSeedProvider
parameters：
＃seeds实际上是一个逗号分隔的地址列表。
＃Ex：< ip1>，< ip2>，< ip3>
- 种子：127.0.0.1
conf / cassandra-env.sh < h1>
＃指定Cassandra可用于
＃JMX连接的默认端口。
JMX_PORT =7200
＃指定Cassandra可用于
＃JMX连接的默认端口。
JMX_PORT =7200
I have a scenario to run cassandra of two different versions in the same machine but at different ports.
I started one cluster with following cassandra config at port 9161,
# TCP port, for commands and data
storage_port: 7000
# SSL port, for encrypted communication. Unused unless enabled in
# encryption_options
ssl_storage_port: 7004
port for the CQL native transport to listen for clients on
native_transport_port: 9043
port for Thrift to listen for clients on
rpc_port: 9161
seed_provider:
# Addresses of hosts that are deemed contact points.
# Cassandra nodes use this list of hosts to find each other and learn
# the topology of the ring. You must change this if you are running
# multiple nodes!
- class_name: org.apache.cassandra.locator.SimpleSeedProvider
parameters:
# seeds is actually a comma-delimited list of addresses.
# Ex: "<ip1>,<ip2>,<ip3>"
- seeds: "127.0.0.1"
It runs well,
$ /usr/local/apache-cassandra-2.1.1/bin/cassandra -f
...
INFO 05:08:42 Loading settings from file:/usr/local/apache-cassandra-2.1.1/conf/cassandra.yaml
...
INFO 05:09:29 Starting listening for CQL clients on localhost/127.0.0.1:9043...
INFO 05:09:29 Binding thrift service to localhost/127.0.0.1:9161
INFO 05:09:29 Listening for thrift clients...
INFO 05:19:25 No files to compact for user defined compaction
$ jps
5866 CassandraDaemon
8848 Jps
However while starting another cassandra cluster configured to run at port 9160 with config,
# TCP port, for commands and data
storage_port: 7000
# SSL port, for encrypted communication. Unused unless enabled in
# encryption_options
ssl_storage_port: 7004
port for the CQL native transport to listen for clients on
native_transport_port: 9042
port for Thrift to listen for clients on
rpc_port: 9160
seed_provider:
# Addresses of hosts that are deemed contact points.
# Cassandra nodes use this list of hosts to find each other and learn
# the topology of the ring. You must change this if you are running
# multiple nodes!
- class_name: org.apache.cassandra.locator.SimpleSeedProvider
parameters:
# seeds is actually a comma-delimited list of addresses.
# Ex: "<ip1>,<ip2>,<ip3>"
- seeds: "127.0.0.1"
it fails with message
$ /usr/local/apache-cassandra-2.0.11/bin/cassandra -f
Unable to bind JMX, is Cassandra already running?
How can I make it run two different version of cassandra in the same machine?
The problem is that I have no permission to stop the previous version. Neither can I use https://github.com/pcmanus/ccm
解决方案
Well I fixed it with changing few more configurations which are storage_port/ssl_storage_port in conf/cassandra.yaml and JMX_PORT in conf/cassandra-env.sh,
conf/cassandra.yaml
# TCP port, for commands and data
storage_port: 7004
# SSL port, for encrypted communication. Unused unless enabled in
# encryption_options
ssl_storage_port: 7005
port for the CQL native transport to listen for clients on
native_transport_port: 9043
port for Thrift to listen for clients on
rpc_port: 9161
seed_provider:
# Addresses of hosts that are deemed contact points.
# Cassandra nodes use this list of hosts to find each other and learn
# the topology of the ring. You must change this if you are running
# multiple nodes!
- class_name: org.apache.cassandra.locator.SimpleSeedProvider
parameters:
# seeds is actually a comma-delimited list of addresses.
# Ex: "<ip1>,<ip2>,<ip3>"
- seeds: "127.0.0.1"
conf/cassandra-env.sh
# Specifies the default port over which Cassandra will be available for
# JMX connections.
JMX_PORT="7200"
