先下载 Cassandra
wget https://dlcdn.apache.org/cassandra/4.0.1/apache-cassandra-4.0.1-bin.tar.gz
解压缩并放到 /opt/cassandra
tar xzvf apache-cassandra-4.0.1-bin.tar.gz sudo mv apache-cassandra-4.0.1 /opt/cassandra
修改 IP binding
vi /opt/cassandra/conf/cassandra.yaml #listen_address: localhost listen_address: 192.168.50.15 #rpc_address: localhost rpc_address: 192.168.50.15 - seeds: "192.168.50.15:7000" #- seeds: "127.0.0.1:7000"
建立 cassandra.pid
cd /var/run sudo touch cassandra.pid sudo chmod 666 cassandra.pid
起动 cassandra
/opt/cassandra/bin/cassandra -p /var/run/cassandra.pid
查看 cassandra 状态
