实战Puppet 集中配置管理系统(2)——apache与nginx模块配

89788

   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)[iyunv@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
   
    ServerName <%= domainname %>
    DocumentRoot /var/www/<%= domainname %>
    ErrorLog logs/<%= domainname %>_error.log
    CustomLog logs/<%= domainname %>_access.log common
   

#vim /etc/puppet/manifests/nodes/server4.pp
    node 'server2.example.com' {
include httpd
httpd::vhost { 'server2.example.com':
domainname => "server2.example.com",
}
httpd::vhost { 'www2.example.com':
        domainname => "www2.example.com",
        }
    }
# vim /etc/puppet/modules/httpd/files/httpd.conf
    990 NameVirtualHost *:80

5)在server2 上测试：
#puppet agent --server server2.example.com --no-daemonize -vt
//在/var/www下会生成server2.example.com  www2.example.com两个目录

6)在主机上添加解析，浏览器上测试
访问server2.example.com
　　www2.example.com
