单节点安装
cassandra由Java开发,需要提前配置JDK环境
开源版本安装
=======================================================

wget http://archive.apache.org/dist/cassandra/3.11.6/apache-cassandra-3.11.6-src.tar.gz

vim conf/cassandra-env.sh
MAX_HEAP_SIZE="4G"
HEAP_NEWSIZE="800M"
vim conf/cassandra.yaml
authenticator: PasswordAuthenticator
useradd cassandra
chown -R cassandra.cassandra /opt/app/apache-cassandra-2.1.21/
pkill -f CassandraDaemon
su - cassandra -c /opt/app/apache-cassandra-2.1.21/bin/cassandra
# netstat -tunlp |grep 9042 tcp 0 0 127.0.0.1:9042 0.0.0.0:* LISTEN 6724/java
cd /opt/app/apache-cassandra-2.1.21
./bin/cqlsh -u cassandra -p cassandra localhost
CREATE USER automng WITH PASSWORD ‘Automng_123‘ SUPERUSER ;
./bin/cqlsh -u automng -p Automng_123 127.0.0.1
这里使用的是公有云,首先要开放其9042端口,然后修改几个IP地址,修改为内网IP即可,不需要填写公网IP
# cat conf/cassandra.yaml |grep 172 - seeds: "172.21.0.12" listen_address: 172.21.0.12 rpc_address: 172.21.0.12
然后重启cassandra
pkill -f CassandraDaemon
su - cassandra -c /opt/app/apache-cassandra-2.1.21/bin/cassandra
3.11.6安装记录
tar -xvf apache-cassandra-3.11.6-bin.tar.gz -C /opt/app/
chown -R cassandra.cassandra /opt/app/apache-cassandra-3.11.6/
修改Java堆内存与密码认证方式后,然后启动
su - cassandra -c /opt/app/apache-cassandra-3.11.6/bin/cassandra
./bin/cqlsh -u cassandra -p cassandra localhost
su: warning: cannot change directory to /home/cassandra: No such file or directory
root@db:~# mkdir /home/cassandra
root@db:~# chown -R cassandra.cassandra /home/cassandra/
root@db:~# chmod -R 755 /home/cassandra/

附·官方个人电脑安装指导
Your Own Computer This option is provided for users that really prefer to run exercises outside of a virtual machine or cloud instance. However due to the variety of different computing environments, no other support is provided outside of this document. We recommend using one of the other exercise environment options instead to avoid setup issues.
Prerequisite Software Java 8 – OpenJDK 8 or Oracle Java SE 8 (1.8.0_151 minimum) Python 2.7.x – https://www.python.org/downloads/ DataStax Python driver – https://github.com/datastax/python-driver
Requirements CPU – Multi-core 64-bit CPU Disk Size – 10GB free space Memory – 6GB or more Operating System – Mac OSX / Linux
Instructions 1. Download the DataStax Enterprise 6.0 tarball, available from the DataStax website. 2. Download DS201: Data Files and Scripts from the DS201 Course Assets page and extract the resulting zip file. 3. The extracted files include a script, labwork/config_node, which assumes that you will be installing DSE in the location /home/ubuntu. Edit the script to match the location you will be doing the exercises from. 4. Open a terminal window to start the DS201 exercises
java -version
sudo apt-get install libaio1
curl -L https://downloads.datastax.com/enterprise/dse.tar.gz | tar xz
curl -L https://downloads.datastax.com/enterprise/dse-version_number-bin.tar.gz | tar xz
curl -L https://downloads.datastax.com/enterprise/dse-6.8.1-bin.tar.gz | tar xz
tar -xzvf dse-6.8.1-bin.tar.gz
In the installation_location, make the directories for data and logging directories. For example
mkdir dse-data &&
cd dse-data &&
mkdir data &&
mkdir commitlog &&
mkdir saved_caches &&
mkdir hints &&
mkdir cdc_raw
cd installation_location/resources/cassandra/conf
Update the following lines in the cassandra.yaml file
data_file_directories:
- full_path_to_installation_location/dse-data/data
commitlog_directory: full_path_to_installation_location/dse-data/commitlog
saved_caches_directory: full_path_to_installation_location/dse-data/saved_caches
hints_directory: full_path_to_installation_location/dse-data/hints
cdc_raw_directory: full_path_to_installation_location/cdc_raw
注意事项
For production, be sure to change the cassandra
user. 这里有创建用户的说明。
