一、系统环境
系统环境
CentOS5.8 x86_64
node1.network.com node1 172.16.1.101
node2.network.com node2 172.16.1.105
node3.network.com node3 172.16.1.110
软件版本
cman-2.0.115-124.el5.x86_64.rpm
rgmanager-2.0.52-54.el5.centos.x86_64.rpm
system-config-cluster-1.0.57-17.noarch.rpm
二、准备工作
1、时间同步
[root@node1 ~]# ntpdate s2c.time.edu.cn [root@node2 ~]# ntpdate s2c.time.edu.cn [root@node3 ~]# ntpdate s2c.time.edu.cn 可根据需要在每个节点上定义crontab任务 [root@node1 ~]# which ntpdate /sbin/ntpdate [root@node1 ~]# echo "*/5 * * * * /sbin/ntpdate s2c.time.edu.cn &> /dev/null" >> /var/spool/cron/root [root@node1 ~]# crontab -l */5 * * * * /sbin/ntpdate s2c.time.edu.cn &> /dev/null
2、主机名称要与uname -n，并通过/etc/hosts解析
node1 [root@node1 ~]# hostname node1.network.com [root@node1 ~]# uname -n node1.network.com [root@node1 ~]# sed -i ‘s@\(HOSTNAME=\).*@\1node1.network.com@g‘ /etc/sysconfig/network node2 [root@node2 ~]# hostname node2.network.com [root@node2 ~]# uname -n node2.network.com [root@node2 ~]# sed -i ‘s@\(HOSTNAME=\).*@\1node2.network.com@g‘ /etc/sysconfig/network node3 [root@node3 ~]# hostname node3.network.com [root@node3 ~]# uname -n node3.network.com [root@node3 ~]# sed -i ‘s@\(HOSTNAME=\).*@\1node3.network.com@g‘ /etc/sysconfig/network node1添加hosts解析 [root@node1 ~]# vim /etc/hosts [root@node1 ~]# cat /etc/hosts 127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4 ::1 localhost localhost.localdomain localhost6 localhost6.localdomain6 172.16.1.101 node1.network.com node1 172.16.1.105 node2.network.com node2 172.16.1.110 node3.network.com node3 拷贝此hosts文件至node2 [root@node1 ~]# scp /etc/hosts node2:/etc/ The authenticity of host ‘node2 (172.16.1.105)‘ can‘t be established. RSA key fingerprint is 13:42:92:7b:ff:61:d8:f3:7c:97:5f:22:f6:71:b3:24. Are you sure you want to continue connecting (yes/no)? yes Warning: Permanently added ‘node2,172.16.1.105‘ (RSA) to the list of known hosts. root@node2‘s password: hosts 100% 233 0.2KB/s 00:00 拷贝此hosts文件至node3 [root@node1 ~]# scp /etc/hosts node3:/etc/ The authenticity of host ‘node3 (172.16.1.110)‘ can‘t be established. RSA key fingerprint is 13:42:92:7b:ff:61:d8:f3:7c:97:5f:22:f6:71:b3:24. Are you sure you want to continue connecting (yes/no)? yes Warning: Permanently added ‘node3,172.16.1.110‘ (RSA) to the list of known hosts. hosts 100% 320 0.3KB/s 00:00
3、ssh互信通信
node1 [root@node1 ~]# ssh-keygen -t rsa -f ~/.ssh/id_rsa -P ‘‘ Generating public/private rsa key pair. /root/.ssh/id_rsa already exists. Overwrite (y/n)? n # 我这里已经生成过了 [root@node1 ~]# ssh-copy-id -i ~/.ssh/id_rsa.pub node2 root@node2‘s password: Now try logging into the machine, with "ssh ‘node2‘", and check in: .ssh/authorized_keys to make sure we haven‘t added extra keys that you weren‘t expecting. [root@node1 ~]# setenforce 0 [root@node1 ~]# ssh node2 ‘ifconfig‘ eth0 Link encap:Ethernet HWaddr 00:0C:29:D6:03:52 inet addr:172.16.1.105 Bcast:255.255.255.255 Mask:255.255.255.0 inet6 addr: fe80::20c:29ff:fed6:352/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:9881 errors:0 dropped:0 overruns:0 frame:0 TX packets:11220 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:5898514 (5.6 MiB) TX bytes:1850217 (1.7 MiB) lo Link encap:Local Loopback inet addr:127.0.0.1 Mask:255.0.0.0 inet6 addr: ::1/128 Scope:Host UP LOOPBACK RUNNING MTU:16436 Metric:1 RX packets:16 errors:0 dropped:0 overruns:0 frame:0 TX packets:16 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:1112 (1.0 KiB) TX bytes:1112 (1.0 KiB) 同理node2也需要做同样的双击互信，一样的操作，此处不再演示
4、关闭iptables和selinux
node1
[root@node1 ~]# service iptables stop [root@node1 ~]# vim /etc/sysconfig/selinux [root@node1 ~]# cat /etc/sysconfig/selinux # This file controls the state of SELinux on the system. # SELINUX= can take one of these three values: # enforcing - SELinux security policy is enforced. # permissive - SELinux prints warnings instead of enforcing. # disabled - SELinux is fully disabled. #SELINUX=permissive SELINUX=disabled # SELINUXTYPE= type of policy in use. Possible values are: # targeted - Only targeted network daemons are protected. # strict - Full SELinux protection. SELINUXTYPE=targeted
node2
[root@node2 ~]# service iptables stop [root@node2 ~]# vim /etc/sysconfig/selinux [root@node2 ~]# cat /etc/sysconfig/selinux # This file controls the state of SELinux on the system. # SELINUX= can take one of these three values: # enforcing - SELinux security policy is enforced. # permissive - SELinux prints warnings instead of enforcing. # disabled - SELinux is fully disabled. #SELINUX=permissive SELINUX=disabled # SELINUXTYPE= type of policy in use. Possible values are: # targeted - Only targeted network daemons are protected. # strict - Full SELinux protection. SELINUXTYPE=targeted
node3
[root@node3 ~]# service iptables stop [root@node3 ~]# vim /etc/sysconfig/selinux [root@node3 ~]# cat /etc/sysconfig/selinux # This file controls the state of SELinux on the system. # SELINUX= can take one of these three values: # enforcing - SELinux security policy is enforced. # permissive - SELinux prints warnings instead of enforcing. # disabled - SELinux is fully disabled. #SELINUX=permissive SELINUX=disabled # SELINUXTYPE= type of policy in use. Possible values are: # targeted - Only targeted network daemons are protected. # strict - Full SELinux protection. SELINUXTYPE=targeted
