安装puppet前准备内容
规范ip,主机名，防火墙，双机互信，域名解析
1、修改ip
master [[email protected] etc]# cat /etc/sysconfig/network-scripts/ifcfg-eth0 # Advanced Micro Devices [AMD] 79c970 [PCnet32 LANCE] DEVICE=eth0 BOOTPROTO=static ONBOOT=yes HWADDR=00:0c:29:53:d8:5c IPADDR=192.168.1.10 NETWARK=255.255.255 GATWAY=192.168.1.1 DNS=202.96.128.86 agent01 [[email protected] ~]# cat /etc/sysconfig/network-scripts/ifcfg-eth0 # Advanced Micro Devices [AMD] 79c970 [PCnet32 LANCE] DEVICE=eth0 BOOTPROTO=static ONBOOT=yes HWADDR=00:0c:29:20:ea:2d IPADDR=192.168.1.11 NETWORK=255.255.255.255 GATWAY=192.168.1.1 DNS=202.96.128.86 agnet02 [[email protected] ~]# cat /etc/sysconfig/network-scripts/ifcfg-eth0 # Advanced Micro Devices [AMD] 79c970 [PCnet32 LANCE] DEVICE=eth0 BOOTPROTO=static ONBOOT=yes HWADDR=00:0c:29:9e:d5:92 IPADDR=192.168.1.12 NETWORK=255.255.255.0 GATWAY=192.168.1.1 DNS=202.96.128.86
2、修改主机名
master [[email protected] etc]# cat /etc/sysconfig/network NETWORKING=yes NETWORKING_IPV6=yes #HOSTNAME=localhost.localdomain HOSTNAME=master.puppet GATEWAY=192.168.1.1 agent01 [[email protected] ~]# cat /etc/sysconfig/network NETWORKING=yes NETWORKING_IPV6=yes #HOSTNAME=localhost.localdomain HOSTNAME=agent01.puppet GATEWAY=192.168.1.1 agnet02 [[email protected] ~]# cat /etc/sysconfig/network NETWORKING=yes NETWORKING_IPV6=yes #HOSTNAME=localhost.localdomain HOSTNAME=agent02.puppet GATEWAY=192.168.1.1 修改主机名，需重启后生效。
3、为了减少测试环境的复杂程度，直接关闭防火墙
[[email protected] /]# service iptables stop 清除防火墙规则： [确定] 把 chains 设置为 ACCEPT 策略：filter [确定] 正在卸载 Iiptables 模块： [确定] 设置防火墙开机为关闭 [[email protected] /]# chkconfig iptables off
4、配置agent机器和master机器互信
在master生成公钥 [[email protected] ~]# ssh-keygen Generating public/private rsa key pair. Enter file in which to save the key (/root/.ssh/id_rsa): Created directory ‘/root/.ssh‘. Enter passphrase (empty for no passphrase): Enter same passphrase again: Your identification has been saved in /root/.ssh/id_rsa. Your public key has been saved in /root/.ssh/id_rsa.pub. The key fingerprint is: 17:61:db:30:21:ce:a2:95:8b:64:ff:65:b3:08:d0:c0 [email protected] 复制公钥到agnet机器上 [[email protected] .ssh]# ssh-copy-id -i ~/.ssh/id_rsa.pub 192.168.1.11 [[email protected] .ssh]# ssh-copy-id -i ~/.ssh/id_rsa.pub 192.168.1.12
5、配置域名相互解析
使用host文件直接进行解析配置
[[email protected] /]# cat /etc/hosts # Do not remove the following line, or various programs # that require network functionality will fail. 127.0.0.1 localhost.localdomain localhost ::1 localhost6.localdomain6 localhost6 192.168.1.10 master.puppet 192.168.1.11 agent01.puppet 192.168.1.12 agent02.puppet
将此文件拷贝到其他两台agent机器上
[[email protected] etc]# for i in {1..2};do scp hosts 192.168.1.1$i:/etc/;done
hosts 100% 271 0.3KB/s 00:00
hosts 100% 271 0.3KB/s 00:00
域名解析测试
[[email protected] etc]# ping master.puppet PING master.puppet (192.168.1.10) 56(84) bytes of data. 64 bytes from master.puppet (192.168.1.10): icmp_seq=1 ttl=64 time=1.35 ms 64 bytes from master.puppet (192.168.1.10): icmp_seq=2 ttl=64 time=0.083 ms 64 bytes from master.puppet (192.168.1.10): icmp_seq=3 ttl=64 time=0.030 ms --- master.puppet ping statistics --- 3 packets transmitted, 3 received, 0% packet loss, time 2029ms rtt min/avg/max/mdev = 0.030/0.488/1.351/0.610 ms [[email protected] etc]# ping agent01.puppet PING agent01.puppet (192.168.1.11) 56(84) bytes of data. 64 bytes from agent01.puppet (192.168.1.11): icmp_seq=1 ttl=64 time=1.81 ms 64 bytes from agent01.puppet (192.168.1.11): icmp_seq=2 ttl=64 time=0.213 ms 64 bytes from agent01.puppet (192.168.1.11): icmp_seq=3 ttl=64 time=0.245 ms 64 bytes from agent01.puppet (192.168.1.11): icmp_seq=4 ttl=64 time=0.196 ms --- agent01.puppet ping statistics --- 4 packets transmitted, 4 received, 0% packet loss, time 3060ms rtt min/avg/max/mdev = 0.196/0.616/1.813/0.691 ms [[email protected] etc]# ping agent02.puppet PING agent02.puppet (192.168.1.12) 56(84) bytes of data. 64 bytes from agent02.puppet (192.168.1.12): icmp_seq=1 ttl=64 time=1.97 ms 64 bytes from agent02.puppet (192.168.1.12): icmp_seq=2 ttl=64 time=0.313 ms 64 bytes from agent02.puppet (192.168.1.12): icmp_seq=3 ttl=64 time=0.302 ms
