DB2 HADR TSA高可用性测试--TSA环境配置

• 配置所有节点名及Hosts文件

[root@db2-node01 ~]# more /etc/sysconfig/network
NETWORKING=yes
NETWORKING_IPV6=yes
HOSTNAME=db2-node01
[root@db2-node01 ~]#
[root@db2-node01 ~]# echo $HOSTNAME
db2-node01

[root@db2-node02 ~]# more /etc/sysconfig/network
NETWORKING=yes
NETWORKING_IPV6=yes
HOSTNAME=db2-node02
[root@db2-node02 ~]# echo $HOSTNAME
db2-node02
[root@db2-node02 ~]#

[root@db2-node01 ~]# vi /etc/hosts
# Do not remove the following line, or various programs
# that require network functionality will fail.
127.0.0.1localhost.localdomain localhost
#::1localhost6.localdomain6 localhost6

108.88.3.106 db2-node01
108.88.3.221 db2-node02

[root@db2-node02 ~]# more /etc/hosts
# Do not remove the following line, or various programs
# that require network functionality will fail.
127.0.0.1localhost.localdomain localhost
#::1localhost6.localdomain6 localhost6

108.88.3.106 db2-node01
108.88.3.221 db2-node02
[root@db2-node02 ~]#

• 检测主机名及Hosts配置

[root@db2-node01 ~]# ping db2-node01

• node02上测试

[root@db2-node02 ~]# ping db2-node01
PING db2-node01 (108.88.3.106) 56(84) bytes of data.
64 bytes from db2-node01 (108.88.3.106): icmp_seq=1 ttl=64 time=1.64 ms

[root@db2-node02 ~]#

• 添加CT_MANAGEMENT_SCOPE在所有节点

[root@db2-node01 ~]# vi /etc/profile

export CT_MANAGEMENT_SCOPE=2

[root@db2-node02 ~]# vi /etc/profile

export CT_MANAGEMENT_SCOPE=2

• 所有节点安装RSH服务
  

1.1在node01安装RSH

[root@db2-node01 ~]# rpm -qa | grep -i rsh-server
[root@db2-node01 ~]#yum install rsh-server
[root@db2-node01 ~]#chkconfig xinetd on
[root@db2-node01 ~]#chkconfig rsh on
[root@db2-node01 ~]#chkconfig rlogin on
[root@db2-node01 ~]#/etc/init.d/xinetd restart

1.2、设置RSH远程访问
[root@db2-node01 ~]#vi /root/.rhosts
db2-node01 root
db2-node02 root

1.3、修改kerberos中rsh

[root@db2-node01 ~]#cd /usr/kerberos/bin
[root@db2-node01 ~]#mv rsh rsh.sav
[root@db2-node01 ~]# ln -s /usr/bin/rsh rsh
[root@db2-node01 ~]#/etc/init.d/xinetd restart
[root@db2-node01 ~]# ls -al /usr/bin/rsh

1.4、添加 rsh 到 /etc/securetty 文件中

[root@db2-node01 ~]#echo rsh >>/etc/securetty

1.5、添加DB2实例用户RSH
[root@db2-node01 ~]#vi /home/db2inst2/.rhosts
db2-node01 root
db2-node02 root

1.6、测试
[root@db2-node01 ~]#rsh db2-node01 ls
[root@db2-node01 ~]#rsh db2-node02 ls


2.1 Install RSH on node02

[root@db2-node02 ~]# rpm -qa | grep -i rsh-server
[root@db2-node02 ~]#yum install rsh-server
[root@db2-node02 ~]#chkconfig xinetd on
[root@db2-node02 ~]#chkconfig rsh on
[root@db2-node02 ~]#chkconfig rlogin on
[root @db2-node02 ~]#/etc/init.d/xinetd restart

2.2. Set up RSH remote access
[root@db2-node02 ~]#vi /root/.rhosts
db2-node01 root
db2-node02 root

2.3. Modify rsh in kerberos

[root@db2-node01 ~]#cd /usr/kerberos/bin
[root@db2-node01 ~]#mv rsh rsh.sav
[root@db2-node01 ~]#ln -s /usr/bin/rsh rsh
[root@db2-node01 ~] #/etc/init.d/xinetd restart
[root@db2-node01 ~]# ls -al /usr/bin/rsh

2.4. Add rsh to the /etc/securetty file Medium

[root@db2-node01 ~]#echo rsh >>/etc/securetty


2.5. Add DB2 instance user RSH
[root@db2 -node01 ~]#vi /home/db2inst2/.rhosts
db2-node01 root
db2-node02 root

2.6, test
[root@db2-node01 ~] #rsh db2-node01 ls
[root@db2-node01 ~]#rsh db2-node02 ls

Initialize RSCT cluster node
The following operations are performed by the root user on db2-node01 and db2-node01
[root@db2-node01 ~]##preprpnode db2-node01 db2-node02
[root@db2-node02 ~]##preprpnode db2-node01 db2-node02

• Turn off all node firewalls and selinux

[root@db2-node01 ~]# /etc/init.d/iptables stop
[root@db2-node02 ~]# /etc/ init.d/iptables stop
