puppet实现nginx反代tomcat+memcached

1、准备六台主机,一台puppet,一台nginx反代,两台memcached,两台tomcat

192.168.1.33 puppet.test.com puppet

192.168.1.34 nginx.test.com nginx

192.168.1.35 tomcat1.test.com tomcat1

192.168.1.36 tomcat2.test.com tomcat2

192.168.1.40 memcached1.test.com memcached1

192.168.1.41 memcached2.test.com memcached2

2、puppet主机

vim /etc/hosts

192.168.1.33 puppet.test.com puppet
 
 192.168.1.34 nginx.test.com nginx
 
 192.168.1.35 tomcat1.test.com tomcat1
 
 192.168.1.36 tomcat2.test.com tomcat2
 
 192.168.1.40 memcached1.test.com memcached1
 
 192.168.1.41 memcached2.test.com memcached2

hostname set-hostname puppet.test.com

vim /etc/ssh/ssh_config

StrictHostKeyChecking=no

//加入此条,为了在连接目标主机时不再提示“Are you sure you want to continue connecting”

ssh-keygen -t rsa -P ”

ssh-copy-id -i .ssh/id_rsa.pub root@192.168.1.33

在每台主机的root目录下创建.ssh目录

scp -p .ssh/authorized_keys .ssh/id_rsa{,.pub} nginx:/root/.ssh

scp -p .ssh/authorized_keys .ssh/id_rsa{,.pub} tomcat1:/root/.ssh

scp -p .ssh/authorized_keys .ssh/id_rsa{,.pub} tomcat2:/root/.ssh

scp -p .ssh/authorized_keys .ssh/id_rsa{,.pub} memcached1:/root/.ssh

scp -p .ssh/authorized_keys .ssh/id_rsa{,.pub} memcached2:/root/.ssh

scp -p /etc/ssh/ssh_config nginx:/etc/ssh/

scp -p /etc/ssh/ssh_config tomcat1:/etc/ssh/

scp -p /etc/ssh/ssh_config tomcat2:/etc/ssh/

scp -p /etc/ssh/ssh_config memcached1:/etc/ssh/

scp -p /etc/ssh/ssh_config memcached2:/etc/ssh/

scp /etc/hosts nginx:/etc/

scp /etc/hosts tomcat1:/etc/

scp /etc/hosts tomcat2:/etc/

scp /etc/hosts memcached1:/etc/

scp /etc/hosts memcached2:/etc/

yum install epel-release -y

yum install facter-2.4.6-1.el7.x86_64.rpm puppet-3.8.7-1.el7.noarch.rpm puppet-server-3.8.7-1.el7.noarch.rpm -y

vim /etc/puppet/puppet.conf

environmentpath = $confdir/environments

//服务器工作在哪个环境

puppet master –no-daemonize -v

//启动服务

ss -tln

//监听8140端口

mkdir -pv /etc/puppet/enviroments/{production,testing,development}/{manifests,modules}

mkdir -pv /etc/puppet/enviroments/{production,testing,development}/modules/{nginx,tomcat,httpd,memcached,jdk8}/{manifests,files,templates,lib,spec,tests}

  • memcached

cd /etc/puppet/enviroments/development/modules/memcached

vim manifests/init.pp

class memcached {
     package{'memcached':
         name  => 'memcached',
         ensure  => latest,

         source  => "puppet:///modules/jdk8/java.sh",
     }
 }

export JAVA_HOME=/usr
  • tomcat

/etc/puppet/environments/development

vim modules/tomcat/manifests/init.pp

//allowLinking=”true”表示支持软链接,也就是前面的docBase中的test可以是软链接;path是定义访问路径的,docBase是在服务器上的相对路径。

vim files/tomcat-users.xml

2、到其他主机

同步时间

hostnamectl set-hostname **
.test.com

yum install facter-2.4.6-1.el7.x86_64.rpm puppet-3.8.7-1.el7.noarch.rpm

vim /etc/puppet/puppet.conf

server = puppet.ruopu.com
 listen = true
 environment = development

vim /etc/puppet/auth.conf

path /run
 method save
 auth any
 allow puppet.magedu.com

puppet agent –no-daemonize -v -d

3、puppet主机

puppet cert list

puppet cert sign –all
