Puppet模块(六):zabbix模块及server资源
作用:Zabbix是一款强大的自动化监控软件,通过puppet自动部署zabbix客户端。
1、服务端配置zabbix模块
(1)模块清单

(2)定义参数类
(3)定义安装类
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 | [root@puppet ~]# vi /etc/puppet/modules/zabbix/manifests/install.pp class zabbix::install { include zabbix::install::files, zabbix::install::sh } #文件子类 class zabbix::install::files { #创建软件存放目录 file { "/home/zabbix": ensure => directory, } #复制源码包 file { "zabbix-agent": name => "/home/zabbix/${zabbix::params::zabbixversion}.tar.gz", ensure => file, owner => 'root', group => 'root', source => "puppet:///modules/zabbix/${zabbix::params::zabbixversion}.tar.gz", require => File["/home/zabbix"], } #复制安装脚本,必须是unix格式 file { "zabbix-install": name => "/home/zabbix/zabbix_install.sh", ensure => file, owner => 'root', group => 'root', mode => '0755', content => template("zabbix/zabbix_install_sh.erb"), require => File["/home/zabbix"], } } #脚本子类 class zabbix::install::sh { #安装依赖软件包 package { ["gcc","curl"]:#,"curl-devel","net-snmp","net-snmp-devel","perl-DBI" ensure => installed, before => Exec["/bin/bash zabbix_install.sh"], } #执行安装脚本 exec { "/bin/bash zabbix_install.sh": cwd => "/home/zabbix", creates => "/etc/init.d/zabbix_agentd", #脚本执行成功后会生成这个文件,当文件存在了就不再执行此资源 require => Class["zabbix::install::files"], } } |

说明:使用安装脚本可以简化很多代码,简省puppet资源,也可以使用exec来执行tar、configure、make等命令来进行部署。
(4)定义配置类
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 | [root@puppet ~]# vi /etc/puppet/modules/zabbix/manifests/config.pp class zabbix::config { include zabbix::config::files, zabbix::config::iptables } #配置文件子类 class zabbix::config::files { file { "/usr/local/zabbix_agent/etc/zabbix_agentd.conf": ensure => present, owner => 'root', group => 'root', mode => '0600', content => template("zabbix/zabbix_agentd_conf.erb"), require => Class["zabbix::install"], notify => Class["zabbix::service"], } file { "/usr/local/zabbix_agent/sbin/discovertcpport.sh": ensure => present, owner => 'root', group => 'root', mode => '0755', source => "puppet:///modules/zabbix/discovertcpport.sh", require => Class["zabbix::install"], } #指定日志属主,否则进程启动时报错cannot open [/var/log/zabbix_agentd.log]: [13] Permission denied file { "/var/log/zabbix_agentd.log": ensure => present, owner => 'zabbix', group => 'zabbix', require => Class["zabbix::install"], } } #防火墙设置子类 class zabbix::config::iptables { service { "iptables": ensure => running, enable => true, hasstatus => true, hasrestart => true, } exec { 'iptables -I INPUT -p tcp --dport 10050:10051 -j ACCEPT': unless => 'grep "tcp --dport 10050:10051" /etc/sysconfig/iptables 2>/dev/null', require => Service["iptables"], notify => Exec["service iptables save"], } exec { 'iptables -I INPUT -p udp --dport 10050:10051 -j ACCEPT': unless => 'grep "udp --dport 10050:10051" /etc/sysconfig/iptables 2>/dev/null', require => Service["iptables"], notify => Exec["service iptables save"], } exec { 'service iptables save': refreshonly => true, } } |
1234567891011121314151617181920212223242526272829303132333435363738394041424344454647484950515253[root@puppet ~]# vi /etc/puppet/modules/zabbix/manifests/config.ppclass zabbix::config { include zabbix::config::files, zabbix::config::iptables}#配置文件子类class zabbix::config::files { file { "/usr/local/zabbix_agent/etc/zabbix_agentd.conf": ensure => present, owner => 'root', group => 'root', mode => '0600', content => template("zabbix/zabbix_agentd_conf.erb"), require => Class["zabbix::install"], notify => Class["zabbix::service"], } file { "/usr/local/zabbix_agent/sbin/discovertcpport.sh": ensure => present, owner => 'root', group => 'root', mode => '0755', source => "puppet:///modules/zabbix/discovertcpport.sh", require => Class["zabbix::install"], } #指定日志属主,否则进程启动时报错cannot open [/var/log/zabbix_agentd.log]: [13] Permission denied file { "/var/log/zabbix_agentd.log": ensure => present, owner => 'zabbix', group => 'zabbix', require => Class["zabbix::install"], }}#防火墙设置子类class zabbix::config::iptables { service { "iptables": ensure => running, enable => true, hasstatus => true, hasrestart => true, } exec { 'iptables -I INPUT -p tcp --dport 10050:10051 -j ACCEPT': unless => 'grep "tcp --dport 10050:10051" /etc/sysconfig/iptables 2>/dev/null', require => Service["iptables"], notify => Exec["service iptables save"], } exec { 'iptables -I INPUT -p udp --dport 10050:10051 -j ACCEPT': unless => 'grep "udp --dport 10050:10051" /etc/sysconfig/iptables 2>/dev/null', require => Service["iptables"], notify => Exec["service iptables save"], } exec { 'service iptables save': refreshonly => true, }}
说明:这里的防火墙规则配置可以应用到很多地方,首先要保证iptables服务启动,否则规则保存不进文件,然后添加临时规则,通知iptables服务保存,unless和refreshonly保证了Exec资源只执行一次就完成任务。
(5)定义配置文件模板
1 2 3 4 5 6 7 8 | [root@puppet ~]# vi /etc/puppet/modules/zabbix/template/zabbix_agentd_conf.erb ### puppet config ### LogFile=/var/log/zabbix_agentd.log Server=<%= scope.lookupvar('zabbix::params::zabbixserver') %> #参数类中定义的服务器名称 Hostname=<%= fqdn %> #使用facter fqdn获取客户端的计算机全名 UnsafeUserParameters=1 EnableRemoteCommands=1 UserParameter=tcpportlisten,/usr/local/zabbix_agent/sbin/discovertcpport.sh "$1" |
12345678[root@puppet ~]# vi /etc/puppet/modules/zabbix/template/zabbix_agentd_conf.erb### puppet config ###LogFile=/var/log/zabbix_agentd.logServer=<%= scope.lookupvar('zabbix::params::zabbixserver') %> #参数类中定义的服务器名称Hostname=<%= fqdn %> #使用facter fqdn获取客户端的计算机全名UnsafeUserParameters=1EnableRemoteCommands=1UserParameter=tcpportlisten,/usr/local/zabbix_agent/sbin/discovertcpport.sh "$1"
说明:关于zabbix的配置就不详述了,可以看我关于zabbix的相关博文。
(6)定义安装文件模板
1 2 3 4 5 6 7 8 9 10 11 | [root@puppet ~]# vi /etc/puppet/modules/zabbix/template/zabbix_install_sh.erb #!/bin/bash cd /home/zabbix useradd zabbix -s /sbin/nologin tar zvxf <%= scope.lookupvar('zabbix::params::zabbixversion') %>.tar.gz cd <%= scope.lookupvar('zabbix::params::zabbixversion') %> ./configure --prefix=/usr/local/zabbix_agent --enable-agent make install cp /usr/local/zabbix_agent/sbin/zabbix_agentd /etc/init.d/ chmod +x /etc/init.d/zabbix_agentd fi |
1234567891011[root@puppet ~]# vi /etc/puppet/modules/zabbix/template/zabbix_install_sh.erb#!/bin/bashcd /home/zabbixuseradd zabbix -s /sbin/nologintar zvxf <%= scope.lookupvar('zabbix::params::zabbixversion') %>.tar.gzcd <%= scope.lookupvar('zabbix::params::zabbixversion') %>./configure --prefix=/usr/local/zabbix_agent --enable-agentmake installcp /usr/local/zabbix_agent/sbin/zabbix_agentd /etc/init.d/chmod +x /etc/init.d/zabbix_agentdfi
说明:通过参数定义软件版本和服务器地址,模板文件就不用因为这两个值的不同再修改了。
注意:windows下编辑的文件格式是doc,在linux下无法执行(.sh文件),要转换成unix格式。
在linux下转换文件格式方法:
1 2 3 4 | [root@puppet ~]# vi /etc/puppet/modules/zabbix/template/zabbix_install_sh.erb :set ff? #显示fileforma=dos就是windows格式 :set fileformat=unix #转换成unix格式 :wq! #保存退出 |
1234[root@puppet ~]# vi /etc/puppet/modules/zabbix/template/zabbix_install_sh.erb:set ff? #显示fileforma=dos就是windows格式:set fileformat=unix #转换成unix格式:wq! #保存退出
在windows下转换文件格式方法(推荐):
UltraEdit编辑器:文件File-->转换Conversions-->DOS转UNIX
(7)定义服务类
1 2 3 4 5 6 7 8 9 | [root@puppet ~]# vi /etc/puppet/modules/zabbix/manifests/service.pp class zabbix::service { service { "zabbix_agentd": ensure => running, start => "/etc/init.d/zabbix_agentd start", stop => "ps ax|grep zabbix_agentd|grep -v grep |awk '{print \$1}'|xargs kill -9", #$1前要加个\进行转义,否则被认为是puppet变量而无效 require => Class["zabbix::config"], } } |
123456789[root@puppet ~]# vi /etc/puppet/modules/zabbix/manifests/service.ppclass zabbix::service { service { "zabbix_agentd": ensure => running, start => "/etc/init.d/zabbix_agentd start", stop => "ps ax|grep zabbix_agentd|grep -v grep |awk '{print \$1}'|xargs kill -9", #$1前要加个\进行转义,否则被认为是puppet变量而无效 require => Class["zabbix::config"], }}
说明:客户端zabbix_agentd服务的service restart|stop|status没有反应,因此自定义启动和关闭命令来实现重启效果。
(8)定义zabbix主类
1 2 3 4 5 6 | [root@puppet ~]# vi /etc/puppet/modules/zabbix/manifests/init.pp class zabbix { Exec { path => "/usr/bin:/bin:/usr/sbin:/sbin" } include zabbix::params include zabbix::install, zabbix::config, zabbix::service } |
123456[root@puppet ~]# vi /etc/puppet/modules/zabbix/manifests/init.ppclass zabbix { Exec { path => "/usr/bin:/bin:/usr/sbin:/sbin" } include zabbix::params include zabbix::install, zabbix::config, zabbix::service}
(9)定义节点文件,调用模块
(10)应用节点文件
1 2 | [root@puppet ~]# vi /etc/puppet/manifests/site.pp import "centostest.pp" |
12[root@puppet ~]# vi /etc/puppet/manifests/site.ppimport "centostest.pp"
(11)下载zabbix源码包
下载Zabbix Sources中的源码包,目前是2.4.2和2.2.7版本
我的zabbix服务器安装的2.2.5版本
(12)编写自动监控"监听端口"脚本
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 | [root@puppet ~]# vi /etc/puppet/modules/zabbix/files/discovertcpport.sh #!/bin/bash portarray=(`netstat -tnlp|egrep -i "$1"|awk {'print $4'}|awk -F':' '{if ($NF~/^[0-9]*$/) print $NF}'|sort |uniq 2>/dev/null`) length=${#portarray[@]} printf "{\n" printf '\t'"\"data\":[" for ((i=0;i<$length;i++)) do printf '\n\t\t{' printf "\"{#TCP_PORT}\":\"${portarray[$i]}\"};" if [ $i -lt $[$length-1] ];then printf ',' fi done printf "\n\t]\n" printf "}\n" |
12345678910111213141516[root@puppet ~]# vi /etc/puppet/modules/zabbix/files/discovertcpport.sh#!/bin/bashportarray=(`netstat -tnlp|egrep -i "$1"|awk {'print $4'}|awk -F':' '{if ($NF~/^[0-9]*$/) print $NF}'|sort |uniq 2>/dev/null`)length=${#portarray[@]}printf "{\n"printf '\t'"\"data\":["for ((i=0;i<$length;i++))do printf '\n\t\t{' printf "\"{#TCP_PORT}\":\"${portarray[$i]}\"};" if [ $i -lt $[$length-1] ];then printf ',' fidoneprintf "\n\t]\n"printf "}\n"
说明:这是给zabbix用来监控客户端正在监听的端口用的脚本,详见我的zabbix相关博文。
注意:.sh脚本文件,格式必须是unix格式才能执行,按第(5)节中的方法修改。
2、测试
(1)客户端执行puppet agent -t同时查看日志

1 2 3 4 5 6 7 8 9 10 11 | [root@centostest ~]# service iptables status 表格:filter Chain INPUT (policy ACCEPT) num target prot opt source destination 1 ACCEPT udp -- 0.0.0.0/0 0.0.0.0/0 udp dpts:10050:10051 2 ACCEPT tcp -- 0.0.0.0/0 0.0.0.0/0 tcp dpts:10050:10051 3 ACCEPT all -- 0.0.0.0/0 0.0.0.0/0 state RELATED,ESTABLISHED 4 ACCEPT icmp -- 0.0.0.0/0 0.0.0.0/0 5 ACCEPT all -- 0.0.0.0/0 0.0.0.0/0 6 ACCEPT tcp -- 0.0.0.0/0 0.0.0.0/0 state NEW tcp dpt:22 7 REJECT all -- 0.0.0.0/0 0.0.0.0/0 reject-with icmp-host-prohibited |

结论:成功启动防火墙并添加了两条规则
3、测试服务重启
(1)查看进程是否启动,以及进程的PID(1)
1 2 3 4 5 6 | [root@centostest ~]# ps aux|grep zabbix zabbix 45252 0.0 0.0 17592 716 ? S 09:20 0:00 /etc/init.d/zabbix_agentd: collector [idle 1 sec] zabbix 45253 0.0 0.0 17592 624 ? S 09:20 0:00 /etc/init.d/zabbix_agentd: listener #1 [waiting for connection] zabbix 45254 0.0 0.0 17592 624 ? S 09:20 0:00 /etc/init.d/zabbix_agentd: listener #2 [waiting for connection] zabbix 45255 0.0 0.0 17592 624 ? S 09:20 0:00 /etc/init.d/zabbix_agentd: listener #3 [waiting for connection] root 47201 0.0 0.0 103256 848 pts/2 S+ 09:22 0:00 grep zabbix |
123456[root@centostest ~]# ps aux|grep zabbixzabbix 45252 0.0 0.0 17592 716 ? S 09:20 0:00 /etc/init.d/zabbix_agentd: collector [idle 1 sec]zabbix 45253 0.0 0.0 17592 624 ? S 09:20 0:00 /etc/init.d/zabbix_agentd: listener #1 [waiting for connection]zabbix 45254 0.0 0.0 17592 624 ? S 09:20 0:00 /etc/init.d/zabbix_agentd: listener #2 [waiting for connection]zabbix 45255 0.0 0.0 17592 624 ? S 09:20 0:00 /etc/init.d/zabbix_agentd: listener #3 [waiting for connection]root 47201 0.0 0.0 103256 848 pts/2 S+ 09:22 0:00 grep zabbix
(2)修改配置文件模板
在zabbix_agentd_conf.erb中加入一行
1 | #test service restart |
1#test service restart
(3)客户端执行puppet agent -t同时查看日志
1 2 3 | [root@centostest ~]# tailf /var/log/messages Nov 13 09:33:28 centostest puppet-agent[62959]: (/Stage[main]/Zabbix::Config/File[/usr/local/zabbix_agent/etc/zabbix_agentd.conf]/content) content changed '{md5}7f16ab238a0febff5d3330a4b4b341c4' to '{md5}d2b43f63f0c101966d8ea32356e0fcdc' Nov 13 09:33:28 centostest puppet-agent[62959]: (/Stage[main]/Zabbix::Service/Service[zabbix_agentd]) Triggered 'refresh' from 1 events |
123[root@centostest ~]# tailf /var/log/messagesNov 13 09:33:28 centostest puppet-agent[62959]: (/Stage[main]/Zabbix::Config/File[/usr/local/zabbix_agent/etc/zabbix_agentd.conf]/content) content changed '{md5}7f16ab238a0febff5d3330a4b4b341c4' to '{md5}d2b43f63f0c101966d8ea32356e0fcdc'Nov 13 09:33:28 centostest puppet-agent[62959]: (/Stage[main]/Zabbix::Service/Service[zabbix_agentd]) Triggered 'refresh' from 1 events
(4)再次查看启动进程的PID
1 2 3 4 5 6 | [root@centostest ~]# ps aux|grep zabbixroot 3016 0.0 0.0 103256 840 pts/2 S+ 09:36 0:00 grep zabbix zabbix 63190 0.0 0.0 17592 748 ? S 09:33 0:00 /etc/init.d/zabbix_agentd start zabbix 63191 0.0 0.0 17592 728 ? S 09:33 0:00 /etc/init.d/zabbix_agentd: collector [idle 1 sec] zabbix 63192 0.0 0.0 17592 624 ? S 09:33 0:00 /etc/init.d/zabbix_agentd: listener #1 [waiting for connection] zabbix 63193 0.0 0.0 17592 624 ? S 09:33 0:00 /etc/init.d/zabbix_agentd: listener #2 [waiting for connection] zabbix 63194 0.0 0.0 17592 624 ? S 09:33 0:00 /etc/init.d/zabbix_agentd: listener #3 [waiting for connection] |
123456[root@centostest ~]# ps aux|grep zabbixroot 3016 0.0 0.0 103256 840 pts/2 S+ 09:36 0:00 grep zabbixzabbix 63190 0.0 0.0 17592 748 ? S 09:33 0:00 /etc/init.d/zabbix_agentd startzabbix 63191 0.0 0.0 17592 728 ? S 09:33 0:00 /etc/init.d/zabbix_agentd: collector [idle 1 sec]zabbix 63192 0.0 0.0 17592 624 ? S 09:33 0:00 /etc/init.d/zabbix_agentd: listener #1 [waiting for connection]zabbix 63193 0.0 0.0 17592 624 ? S 09:33 0:00 /etc/init.d/zabbix_agentd: listener #2 [waiting for connection]zabbix 63194 0.0 0.0 17592 624 ? S 09:33 0:00 /etc/init.d/zabbix_agentd: listener #3 [waiting for connection]
结论:可以看到进程PID改变了,配置文件的更新成功触发服务重启,使用了自定义的start和stop命令来完成重启过程。
总结:成功部署了Zabbix agent端,能通过puppet管理配置文件,自动重启zabbix进程,
之后就是在zabbix服务器上添加对centostest的监控了,这里不详述,经测试监控成功。
4、service服务资源
#默认采用/etc/init.d/下的脚本进行服务管理,自定义的脚本需要加入该目录并在脚本中定义chkconfig
1 2 3 4 5 6 7 8 | service { 'nginx': #标题等于name参数,服务名 ensure => running,#确保服务运行 enable => true, #开机启动服务 hasrestart => true, #是否支持service nginx restart命令,重启 hasstatus => true, #是否支持service nginx status命令,查看状态,当服务未启动,会执行重启 subscribe => File["nginx.conf"], #当nginx.conf有变更时,执行此服务资源(重启) restart => "/etc/init.d/nginx reload", #指定重启命令,只需重新加载配置文件即可 } |
