实战Puppet 集中配置管理系统(2)——apache与nginx模块配置

本次实验内容紧接上次实验，上次博客主要介绍PUPPET的安装认证与资源定义，这次主要写apache与nginx模块的应用。上次实验内容：

实战Puppet 集中配置管理系统(1)——认证与资源定义

本次实验内容：

1.建立节点文件

2.编写apache模块

3.编写nginx模块

4.模板应用(添加虚拟主机配置)

1.不同节点的定义

1.1. 在 puppetmaster（服务器server1端） 编辑 site.pp

# vim /etc/puppet/manifests/site.pp

import "nodes/*.pp"

1.2. 建立节点文件

#mkdir -p /etc/puppet/manifests/nodes

# vi /etc/puppet/manifests/nodes/server2.pp

node 'server2.example.com' {

file { "/var/www/html/index.html":

content => "server2.example.com"

}

}

# vi /etc/puppet/manifests/nodes/server3.pp

node 'server3.example.com' {

file { "/var/www/html/index.html":content => "server3.example.com"

}

}

1.3在client上测试：

　　#puppet agent --server server1.example.com --no-daemonize -vt

2.编写apache模块

#mkdir -p /etc/puppet/modules/httpd/manifests

#mkdir -p /etc/puppet/modules/httpd/files

#cd /etc/puppet/modules/httpd/manifests

#vim install.pp

class httpd::install {

package { "httpd" :

ensure => present

}

}

#vim service.pp

class httpd::service

{

service {

"httpd":

ensure => running,

require => Class["httpd::install","httpd::config"]

}

}

#vim config.pp

class httpd::config {

file {

"/etc/httpd/conf/httpd.conf":

source => "puppet:///modules/httpd/httpd.conf",

require => Class["httpd::install"],

notify => Class["httpd::service"]

}

}

#vim init.pp

class httpd {

include httpd::install,httpd::config,httpd::service

}

#cd /etc/puppet/modules/httpd/files

#cp /etc/httpd/conf/httpd.conf .

#cd /etc/puppet/manifests/nodes

#vim server2.pp

node 'server2.example.com' {

include httpd

file { "/var/www/html/index.html":

content => "server2.example.com"

}

}

在server2上测试：

#puppet agent --server server1.example.com --no-daemonize -vt

3.编写nginx模块

1) #mkdir -p /etc/puppet/modules/nginx/manifests

2) #mkdir -p /etc/puppet/modules/nginx/files

3) #cd /etc/puppet/modules/nginx/manifests

#vim install.pp

class nginx::install{

package {

["pcre-devel","gcc","openssl-devel"]:

ensure => present

}

file {

"/mnt/nginx-1.8.0.tar.gz":

source => "puppet:///modules/nginx/nginx-1.8.0.tar.gz";

"/mnt/install-nginx.sh":

source => "puppet:///modules/nginx/install-nginx.sh"

}

exec {

"install nginx":

command => "sh /mnt/install-nginx.sh",

path => "/bin:/usr/bin:/sbin:/usr/sbin",

require => File["/mnt/install-nginx.sh","/mnt/nginx-1.8.0.tar.gz"],

creates => "/usr/local/lnmp/nginx/sbin/nginx"

#provider => shell,

}

}

#vim service.pp

class nginx::service {

exec {

"nginx start":

command => "/usr/local/lnmp/nginx/sbin/nginx",

require => Class["nginx::install"],

creates => "/usr/local/lnmp/nginx/logs/nginx.pid"

}

}

#vim config.pp

class nginx::config {

file {

"/usr/local/lnmp/nginx/conf/nginx.conf":

source => "puppet:///modules/nginx/nginx.conf",

require => Class["nginx::service"]

}

exec {

"nginx reload":

command => "/usr/local/lnmp/nginx/sbin/nginx -s reload",

refreshonly => true,

subscribe => File["/usr/local/lnmp/nginx/conf/nginx.conf"]

}

}

#cd /etc/puppet/modules/nginx/files/

#vim install-nginx.sh

#!/bin/bash

cd /mnt

tar -zxf nginx-1.8.0.tar.gz

cd nginx-1.8.0

./configure --prefix=/usr/local/lnmp/nginx --with-http_ssl_module --with-http_stub_status_module

make && make install

5)[root@server1 files]# ls

install-nginx.sh nginx-1.8.0.tar.gz nginx.conf

#cd /etc/puppet/manifests/nodes　

#vim server3.pp

node 'server3.example.com' {

include nginx

}

在server3上测试：

　　#puppet agent --server server1.example.com --no-daemonize -vt

4.模板应用(添加虚拟主机配置):

文件存放在 templates 目录中,以*.erb 结尾。

# vim /etc/puppet/modules/httpd/manifests/init.pp

　　//#添加以下行

define httpd::vhost($domainname) {

file { "/etc/httpd/conf.d/${domainname}_vhost.conf":

content => template("httpd/httpd_vhost.conf.erb"),

require => Class["httpd::install"],

notify => Class["httpd::service"]

}

file { "/var/www/$domainname":

ensure => directory

}

file { "/var/www/$domainname/index.html":

content => $domainname

}

#cd /etc/puppet/modules/httpd/templates/

# vim httpd_vhost.conf.erb
