本文详细记录了DB2 purescale 10.5在VMware Workstation 上的安装过程，如果大家看了本人的博文后，实践过程中有什么问题，欢迎加本人微信84077708，我将尽我所能为大家解惑。
配置db2locssh步骤如下：
分别在node01和node02上执行以下命令：
node01:~ # /opt/server_t/db2/linuxamd64/install/setup_db2locssh db2sdin1
DBI1070I Program setup_db2locssh completed successfully.
node02:~ # /opt/server_t/db2/linuxamd64/install/setup_db2locssh db2sdin1
DBI1070I Program setup_db2locssh completed successfully.
然后分别进入node01和node02服务器的/var/db2/db2ssh目录
node01:~ # cd /var/db2/db2ssh/
node01:/var/db2/db2ssh # ls -al
total 420
drwxr-xr-x 6 root root 4096 Jun 17 12:45 .
drwxr-xr-x 3 root root 4096 Jun 17 09:55 ..
drwxr-xr-x 3 root root 4096 Feb 7 2014 .metadata

-rw------- 1 root root 1675 Jun 17 12:45 [email protected]
-rw-r--r-- 1 root root 426 Jun 17 12:45 [email protected]
然后将node01上的/var/db2/db2ssh/目录下的[email protected]文件复制到node02上的/var/db2/db2ssh/目录下。
node01:/var/db2/db2ssh # scp root\@node01.pub root@node02:/var/db2/db2ssh/
[email protected] 100% 426 0.4KB/s 00:00

drwxr-xr-x 6 root root 4096 Jun 17 12:50 .
drwxr-xr-x 3 root root 4096 Jun 17 12:14 ..

-rw------- 1 root root 1679 Jun 17 12:46 [email protected]
-rw-r--r-- 1 root root 426 Jun 17 12:46 [email protected]
然后将node02上的/var/db2/db2ssh/目录下的[email protected]文件复制到node01上的/var/db2/db2ssh/目录下。
node02:/var/db2/db2ssh # scp root\@node02.pub root@node01:/var/db2/db2ssh/
[email protected] 100% 426 0.4KB/s 00:00
接下来验证db2locssh远程登陆是否能功：
node01:/var/db2/db2ssh # ./db2locssh node01 hostname
node01
node01:/var/db2/db2ssh # ./db2locssh node02 hostname
node02
node01:/var/db2/db2ssh #
node02:/var/db2/db2ssh # ./db2locssh node01 hostname
node01
node02:/var/db2/db2ssh # ./db2locssh node02 hostname
node02
node02:/var/db2/db2ssh #
到此，需要的配置就全部配置完成了。
下面可以开始创建实例了。
下面的命令创建DB2 purescale实例，在node01上创建一个CF节点 ， 在node02上创建一个member成员节点。使用/dev/sdc作为共享存储 ， 使用192.168.142.1网关地址作为心跳，tbdev是心跳设备，可以像ORACLE RAC一样使用一个共享磁盘作为心跳设备，也可以使用两个节点都能同时PING通的一个IP地址代替。
node01:/opt/ibm/db2/V10.5/instance # ./db2icrt -cf node01 -cfnet node01.purescale.ibm.local -m node02 -mnet node02.purescale.ibm.local -instance_shared_dev /dev/sdc -instance_shared_mount /db2sd -tbdev 192.168.142.1 -u db2sdfe1 db2sdin1

Post Install Recommendations
-----------------------------
Required steps:
Start using the DB2 product using a valid user ID such as the DB2 instance owner's ID "db2sdin1".
Optional steps:
The network monitor configuration file for the DB2 pureScale instance has been updated on each host to include the IP address of the hosts gateway. The configuration file /var/ct/cfg/netmon.cf was updated on the following hosts: "node01 node02". This file must be modified in the event of future changes to the hosts gateway IP address.
The default database path in the database manager configuration (DFTDBPATH) is set to "/db2sd". This is also the path to the instance shared directory in a shared file system. DFTDBPATH can be updated to a new shared file system created using the db2cluster command (for example, db2cluster -cfs -create -filesystem fs-name). For details on creating a shared file system, see the db2cluster command in the DB2 Information Center.
To validate your installation files, instance, and database functionality, run the Validation Tool, /opt/ibm/db2/V10.5/bin/db2val. For more information, see "db2val" in the DB2 Information Center.
Open First Steps by running "db2fs" using a valid user ID such as the DB2 instance owner's ID. You will need to have DISPLAY set and a supported web browser in the path of this user ID.
Verify that you have access to the DB2 Information Center based on the choices you made during this installation. If you performed a typical or a compact installation, verify that you can access the IBM Web site using the internet. If you performed a custom installation, verify that you can access the DB2 Information Center location specified during the installation.
Ensure that you have the correct license entitlements for DB2 products and features installed on this machine. Each DB2 product or feature comes with a license certificate file (also referred to as a license key) that is distributed on an Activation CD, which also includes instructions for applying the license file. If you purchased a base DB2 product, as well as, separately priced features, you might need to install more than one license certificate. The Activation CD for your product or feature can be downloaded from Passport Advantage if it is not part of the physical media pack you received from IBM. For more information about licensing, search the Information Center (http://publib.boulder.ibm.com/infocenter/db2luw/v10r5/index.jsp) using terms such as "license compliance", "licensing" or "db2licm".
To use your DB2 database product, you must have a valid license. For information about obtaining and applying DB2 license files, see http://pic.dhe.ibm.com/infocenter/db2luw/v10r5/topic/com.ibm.db2.luw.qb.server.doc/doc/c0061199.html.

============================================================
从日志中也可以看到，没有任何错误，到此，DB2 purescale集群实例就创建成功了，现在包含一个CF , ，一个member.
由于环境变量中将DB2AUTOSTART设置为了NO （DB2AUTOSTART=NO），所以实例创建完成后，并不会自动启动，而且，由于我们是在虚拟机中搭建的测试环境，硬件资源很多都并足以让DB2 purescale很好的运行，所以为了让DB2 purescale运行起来，我们在启动实例之前，还需要设置两个环境变量：
db2set DB2_SD_SOCKETS_RESTRICTIONS=false
db2set DB2_CA_TRANSPORT_METHOD=SOCKETS
我们分别在node01和node02上设置这两个环境变量
node01:/opt/ibm/db2/V10.5/instance # su - db2sdin1
db2sdin1@node01:~> db2set DB2_SD_SOCKETS_RESTRICTIONS=false
db2sdin1@node01:~> db2set DB2_CA_TRANSPORT_METHOD=SOCKETS
node02:/var/db2/db2ssh # su - db2sdin1
db2sdin1@node02:~> db2set DB2_SD_SOCKETS_RESTRICTIONS=false
db2sdin1@node02:~> db2set DB2_CA_TRANSPORT_METHOD=SOCKETS
现在实例可以正常启动了，在启动实例之前，如果我们有DB2的license，最好先导入license，我手上有DB2 10.5的通用license。
先在node01上导入license
db2sdin1@node01:~> cd /opt/ibm/db2/V10.5/adm
db2sdin1@node01:/opt/ibm/db2/V10.5/adm> db2lic
db2licd db2licm

然后在node02上导入license
db2sdin1@node02:/opt/ibm/db2/V10.5/adm> db2licm -a /mnt/hgfs/C/db2aese_u.lic
LIC1402I License added successfully.

Expiry date: "Permanent"

Number of licensed authorized users: "25"
下一步，我们查看实例的状态：
db2sdin1@node01:/opt/ibm/db2/V10.5/adm> db2instance -list
ID TYPE STATE HOME_HOST CURRENT_HOST ALERT PARTITION_NUMBER LOGICAL_PORT NETNAME
-- ---- ----- --------- ------------ ----- ---------------- ------------ -------
0 MEMBER STOPPED node02 node02 NO 0 0 node02.purescale.ibm.local
128 CF STOPPED node01 node01 NO - 0 node01.purescale.ibm.local
HOSTNAME STATE INSTANCE_STOPPED ALERT
-------- ----- ---------------- -----
node01 ACTIVE NO NO
node02 ACTIVE NO NO
db2sdin1@node01:/opt/ibm/db2/V10.5/adm>
可以看到，现在DB2 purescale集群中，有一个CF在node01上，有一个MEMBER在node02上，且目前状态都为STOPPED。
现在启动实例：
db2sdin1@node01:~> db2start CF 128
SQL1063N DB2START processing was successful.
db2sdin1@node01:~> db2start member 0
06/17/2017 19:23:27 0 0 SQL1063N DB2START processing was successful.
SQL1063N DB2START processing was successful.
再次查看实例状态
db2sdin1@node01:/opt/ibm/db2/V10.5/adm> db2instance -list
ID TYPE STATE HOME_HOST CURRENT_HOST ALERT PARTITION_NUMBER LOGICAL_PORT NETNAME
-- ---- ----- --------- ------------ ----- ---------------- ------------ -------

HOSTNAME STATE INSTANCE_STOPPED ALERT
-------- ----- ---------------- -----
node01 ACTIVE NO NO
node02 ACTIVE NO NO
db2sdin1@node01:/opt/ibm/db2/V10.5/adm>
CF和MEMBER都启动起来了。
最后要做的事情就是在node01上添加一个MEMBER成员节点，在node02上添加一个CF节点。
在添加MEMBER和CF之前，必须先停止实例。
db2sdin1@node01:~> db2stop member 0
06/17/2017 19:47:26 0 0 SQL1064N DB2STOP processing was successful.
SQL1064N DB2STOP processing was successful.
db2sdin1@node01:~> db2stop CF 128
SQL1064N DB2STOP processing was successful.
然后执行以下命令，先在node01上添加一个member成员节点。
node01:/opt/ibm/db2/V10.5/instance # ./db2iupdt -add -m node01 -mnet node01.purescale.ibm.local db2sdin1

The execution completed successfully.

最后在node02节点上添加一个CF节点：

可以看见，现在node01上有一个CF 和一个MEMBER , node02上有一个CF 和一个MEMBER 。 并且现在全部处于启动状态。
实例创建成功了，其他的操作（比如创建数据库，创建表等）都与单实例一样的，请阅读相关DB2书籍，京东有售。
到此，本次安装任务全部结束。
