生成密钥
在Frontend机器上生成密钥:
1. cd ~/.ssh/
2. ssh-keygen
3. ls -l
total 32 -rw——- 1 root root 1671 Jul 31 11:27 id_rsa -rw——- 1 root root 395 Jul 31 11:27 id_rsa.pub -rw-r–r– 1 root root 10323 Jul 31 16:07 known_hosts
复制密钥
将公共密钥复制到需要同步的服务器上：
1. scp id_rsa.pub root@ondosrv:/root/.ssh/authorized_keys2
测试ssh
在Frontend机器上测试：
1. ssh root@ondosrv
注释：应该不需要输入密码。
编写同步程序
在Frontend机器上编写同步程序：
1. cd /backup
2. vi sync.sh
3. chmod 700 sync.sh
rsync -avlR –delete -e ssh root@192.168.100.1:/usr/share/tomcat5/ /backup/ondo/
rsync -avlR –delete /home/utstar/ […]
1. Config DNS server and domain name
/etc/resolv.conf:
nameserver 192.168.100.7
search pcms.utstar.com
Note:
(1) Test beds machines need to do all of the steps.
(2) R&D environment machines only need the steps marked with red words.
(3) You can also find this article in fronted /home/utstar/installation_doc/
2. If cannot get host’s name from hosts then get it from DNS
/etc/nsswitch.conf:
hosts: […]
1. Set hostname of this machine
/etc/nodename:
The new hostname of the machine, e.g. telusmmu1
2. config net interface and hosts
/etc/hostname.eri0:
The interface name, e.g. telusmmu1
Note: eri0 is interface name, if the machine has second net interface, the second hostname file should be configed, e.g.
/etc/hostname.eri1:
telusmmu1_1
3. Set hosts
/etc/hosts, e.g.:
192.168.102.14 telusmmu2
192.168.99.24 telusmmu2_1
4. This machine will not use as a router
touch /etc/notrouter
5. […]
