ClustrixDB 可以被安装在 CentOS 6.X 任意系统上，也支持安装在多个云环境上 。
第一: 在第一个节点上安装 ClustrixDB
拷贝安装包到一个节点上，解矸并且执行：
shell> tar xvjf current_version.tar.bz2 shell> cd current_version shell> sudo ./clxnode_install.py
第二: 在安装向导里确认调整部分配置选项
在第一个节点上安装ClustrixDB，键入合适的推荐参数。参考： ClustrixDB Installation Options 修改参数值。.
第三: 每个节点的安全性配置
配置 ClustrixDB 对外部应用程序提供服的端口和内部通信端口.
选项 A:允许所有内部结点间的通信
允许节点之间通信的推荐方法是允许在安全环境内的所有端口上的所有节点之间的访问。
选项 B: 开启指定的端口
您还可以打开ClustrixDB所需的特定端口，如下所示。
如果设置了网络安全如防火墙或安全组，则必须允许以下网络流量
在 Clustrix 节点间的内部访问
这些是节点间通信的必需的一些端口. 必须确保集群内部端口是可以访问的.

Step 4: Install Software on Additional Nodes
从第一个配置节点的命令行运行flex_clone，以在其他节点上安装相同版本的ClustrixDB。 需要为集群的每个节点都运行一次。
shell> /opt/clustrix/bin/flex_clone.sh 'new node IP'
Step 5: 配置集群
You can now connect to your new database to configure your cluster. ClustrixDB uses your existingMysqLclient to access the ClustrixDB database. First,execute the following from a command line prompt.
shell> MysqL
Follow this Syntax from the resulting MysqL promptto provide the license number and configure your cluster. Be sure to include the curly bracketsthat surround your license key. (If you do not already have a license key,please contactClustrix Sales.)
SET GLOBAL license = '{license key including curly brackets}'
ALTER CLUSTER ADD 'ip' [,'ip'] ...
For example,this adds three nodes to the cluster.
sql> ALTER CLUSTER ADD '10.2.13.58','10.2.13.55','10.2.13.59';
Step 6: 验证NTP 是否在整个集群中同步
To verify that the clocks are synchronized between all nodes of the cluster,run the following from a command line prompt:
shell> /opt/clustrix/bin/clx cmd 'ntpstat'
See Setting Up NTP for ClustrixDB on CentOS if this step identifies issues.
Step 7: 校验 ClustrixDB 配置
Execute the following from a command line prompt to access the “test” database created during installation:
shell> MysqL -u root test
You should now be able to access the ClustrixGUI Administration UI to monitor and manage your cluster. Provide the IP or hostname of one of the nodes of your cluster in the address bar of a browser and press Enter. Clustrix recommends using Chrome.
Please contact Clustrix Supportif you experience any problems during installation.
