puppet系列之nginx+php日誌切割與salt結合使用

 前面的文章有salt的安裝過程及salt模塊，不清楚的可以去看一下，這篇主要是實現nginx+php 用logrotate來對日誌進行切割，然後再簡單的使用下salt這個工具；

架構如下:

 

以下.pp文件均在/etc/puppet/modules/logrotate/manifests下面，內容如下

init.pp

 

class logrotate (
        $backup_nginx     = "/data/backup/log/nginx",
        $nginx_log        = "/data/log/nginx",
        $nginx_pid        = "/usr/local/nginx/nginx.pid",
        $base_cron        = "/home/cron/logrotate",
       # $backup_nginx_dir = ["/data","/data/backup","/data/backup/log","/data/backup/log/nginx"],
       # $base_cron_dir    = ["/home/cron","/home/cron/logrotate"],
        $backup_php       = "/data/backup/log/php",
        $php_log          = "/usr/local/php/var/log",
        $php_pid          = "/usr/local/php/var/run/php-fpm.pid"

){
        case $operatingsystem {
                centos:{
                        include logrotate::base
                        include logrotate::addcrons
                }
        }
}

base.pp

 

class logrotate::base {
        package {"logrotate":
          ensure => present
        }

      #  file {["/data","/data/backup","/data/backup/log","/data/backup/log/nginx"]:
         file {"$backup_nginx":
          ensure  => present,
        }

      #  file {["/home/cron","/home/cron/logrotate"]:
         file {"$base_cron":
          ensure  => present,
        }

        file {"$backup_php":
          ensure  => present
        }
}

addcrons.pp

class logrotate::addcrons {
        file {"logrotate_nginx_conf":
          owner   => root,
          group   => root,
          mode    => 644,
          path    => "/home/cron/logrotate/logrotate_nginx.conf",
          content => template('logrotate/logrotate_nginx_conf.erb'),
          require => Class["logrotate::base"]
        }

        file {"logrotate_nginx_sh":
          owner   => root,
          group   => root,
          mode    => 644,
          path    => "/home/cron/logrotate/logrotate_nginx.sh",
          content => template('logrotate/logrotate_nginx_sh.erb'),
          require => Class["logrotate::base"]
        }

        cron {"logrotate nginx":
          command   => "bash /home/cron/logrotate/logrotate_nginx.sh",
          user      => root,
          minute    => 59,
          hour      => 23,
          require   => File['logrotate_nginx_conf','logrotate_nginx_sh']
        }

        file {"logrotate_php_conf":
          owner   => root,
          group   => root,
          mode    => 644,
          path    => "/home/cron/logrotate/logrotate_php.conf",
          content => template('logrotate/logrotate_php_conf.erb'),
          require => Class["logrotate::base"]
        }

        file {"logrotate_php_sh":
          owner   => root,
          group   => root,
          mode    => 644,
          path    => "/home/cron/logrotate/logrotate_php.sh",
          content => template('logrotate/logrotate_php_sh.erb'),
          require => Class["logrotate::base"]
        }

        cron {"logrotate php":
          command   => "bash /home/cron/logrotate/logrotate_php.sh",
          user      => root,
          minute    => 59,
          hour      => 23,
          require   => File['logrotate_php_conf','logrotate_php_sh']
        }

}

=================================

以下是四個.erb文件的內容

logrotate_nginx_conf.erb

<%= nginx_log %>/*.log {
    daily
    rotate 7
    missingok
    dateext
    notifempty
    compress
    sharedscripts
    postrotate
    [ ! -f <%= nginx_pid %> ] || /bin/kill -USR1 `/bin/cat <%= nginx_pid %>`
    endscript
    }

logrotate_nginx_sh.erb

#!/bin/bash

BACKUP_DIR=<%= backup_nginx %>  # nginx 備份日誌目錄
NGINX_LOG_PATH=<%= nginx_log %>      # nginx 原始日誌目錄
LOGROTATE_CONF_DIR=`dirname $0`    # logrotate 配置文件目錄，默認跟本腳本同目錄

# 切割日誌
/usr/sbin/logrotate -f $LOGROTATE_CONF_DIR/logrotate_nginx.conf

if [ ! -d $BACKUP_DIR ]; then
    mkdir -p $BACKUP_DIR
fi

# 對切割完的日誌直接重定向壓縮到 BACKUP_DIR
for log in `ls $NGINX_LOG_PATH/*-20[1-9][0-9][0,1][0-9][0-3][0-9].gz`; do
        mv $log $BACKUP_DIR/
done

# 刪除7天前的 nginx 備份日誌
find $BACKUP_DIR/* -name "*.gz" -mtime 7 -type f -exec rm -f {} \;

logrotate_php_conf.erb

<%= php_log %>/*.log {
   daily
   rotate 7
   missingok
   dateext
   notifempty
   compress
   sharedscripts
   postrotate
   [ ! -f <%= php_pid %> ] || /bin/kill -USR1 `/bin/cat <%= php_pid %>`
   endscript
   }

logrotate_php_sh.erb

#!/bin/bash

BACKUP_DIR=<%= backup_php %>         # php 日誌備份目錄
PHP_LOG_PATH=<%= php_log %>              # php 日誌原始目錄
LOGROTATE_CONF_DIR=`dirname $0`         # logrotate 配置文件目錄，默認跟本腳本同目錄

# 切割日誌
/usr/sbin/logrotate -f $LOGROTATE_CONF_DIR/logrotate_php.conf

if [ ! -d $BACKUP_DIR ]; then
    mkdir -p $BACKUP_DIR
fi

# 對切割完日誌進行重定向壓縮到 BACKUP_DIR
for log in `ls $PHP_LOG_PATH/*-20[1-9][0-9][0,1][0-9][0-3][0-9].gz`; do
        mv $log $BACKUP_DIR/
done

# 刪除7天前的備份日誌
find $BACKUP_DIR/* -name "*.gz" -mtime 7 -type f -exec rm -f {} \;

由base.pp可知我們是需要backup_nginx,backup_php,base_cron這些參數的目錄，這個我們可以直接用salt命令來實現

 

salt 'slave.domain.com' cmd.run 'mkdir -p /data/backup/log/nginx&& /data/backup/log/php&& mkdir -p /home/cron/logrotate'

 

salt 'slave.domain.com' cmd.run 'puppet agent --test --server func.domain.com'
