前面的文章有salt的安装过程及salt模块，不清楚的可以去看一下，这篇主要是实现nginx+php 用logrotate来对日志进行切割，然后再简单的使用下salt这个工具；

架构如下:

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

init.pp

1. class logrotate (
2. $backup_nginx     = "/data/backup/log/nginx",
3. $nginx_log        = "/data/log/nginx",
4. $nginx_pid        = "/usr/local/nginx/nginx.pid",
5. $base_cron        = "/home/cron/logrotate",
6. # $backup_nginx_dir = ["/data","/data/backup","/data/backup/log","/data/backup/log/nginx"],
7. # $base_cron_dir    = ["/home/cron","/home/cron/logrotate"],
8. $backup_php       = "/data/backup/log/php",
9. $php_log          = "/usr/local/php/var/log",
10. $php_pid          = "/usr/local/php/var/run/php-fpm.pid"
11. ){
12. case $operatingsystem {
13. centos:{
14. include logrotate::base
15. include logrotate::addcrons
16. }
17. }
18. }

base.pp

1. class logrotate::base {
2. package {"logrotate":
3. ensure => present
4. }
5. #  file {["/data","/data/backup","/data/backup/log","/data/backup/log/nginx"]:
6. file {"$backup_nginx":
7. ensure  => present,
8. }
9. #  file {["/home/cron","/home/cron/logrotate"]:
10. file {"$base_cron":
11. ensure  => present,
12. }
13. file {"$backup_php":
14. ensure  => present
15. }
16. }

addcrons.pp

1. class logrotate::addcrons {
2. file {"logrotate_nginx_conf":
3. owner   => root,
4. group   => root,
5. mode    => 644,
6. path    => "/home/cron/logrotate/logrotate_nginx.conf",
7. content => template('logrotate/logrotate_nginx_conf.erb'),
8. require => Class["logrotate::base"]
9. }
10. file {"logrotate_nginx_sh":
11. owner   => root,
12. group   => root,
13. mode    => 644,
14. path    => "/home/cron/logrotate/logrotate_nginx.sh",
15. content => template('logrotate/logrotate_nginx_sh.erb'),
16. require => Class["logrotate::base"]
17. }
18. cron {"logrotate nginx":
19. command   => "bash /home/cron/logrotate/logrotate_nginx.sh",
20. user      => root,
21. minute    => 59,
22. hour      => 23,
23. require   => File['logrotate_nginx_conf','logrotate_nginx_sh']
24. }
25. file {"logrotate_php_conf":
26. owner   => root,
27. group   => root,
28. mode    => 644,
29. path    => "/home/cron/logrotate/logrotate_php.conf",
30. content => template('logrotate/logrotate_php_conf.erb'),
31. require => Class["logrotate::base"]
32. }
33. file {"logrotate_php_sh":
34. owner   => root,
35. group   => root,
36. mode    => 644,
37. path    => "/home/cron/logrotate/logrotate_php.sh",
38. content => template('logrotate/logrotate_php_sh.erb'),
39. require => Class["logrotate::base"]
40. }
41. cron {"logrotate php":
42. command   => "bash /home/cron/logrotate/logrotate_php.sh",
43. user      => root,
44. minute    => 59,
45. hour      => 23,
46. require   => File['logrotate_php_conf','logrotate_php_sh']
47. }
48. }

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

以下是四个.erb文件的内容

logrotate_nginx_conf.erb

1. <%= nginx_log %>/*.log {
2. daily
3. rotate 7
4. missingok
5. dateext
6. notifempty
7. compress
8. sharedscripts
9. postrotate
10. [ ! -f <%= nginx_pid %> ] || /bin/kill -USR1 `/bin/cat <%= nginx_pid %>`
11. endscript
12. }

logrotate_nginx_sh.erb

1. #!/bin/bash
2. BACKUP_DIR=<%= backup_nginx %>  # nginx 备份日志目录
3. NGINX_LOG_PATH=<%= nginx_log %>      # nginx 原始日志目录
4. LOGROTATE_CONF_DIR=`dirname $0`    # logrotate 配置文件目录，默认跟本脚本同目录
5. # 切割日志
6. /usr/sbin/logrotate -f $LOGROTATE_CONF_DIR/logrotate_nginx.conf
7. if [ ! -d $BACKUP_DIR ]; then
8. mkdir -p $BACKUP_DIR
9. fi
10. # 对切割完的日志直接重定向压缩到 BACKUP_DIR
11. for log in `ls $NGINX_LOG_PATH/*-20[1-9][0-9][0,1][0-9][0-3][0-9].gz`; do
12. mv $log $BACKUP_DIR/
13. done
14. # 删除7天前的 nginx 备份日志
15. find $BACKUP_DIR/* -name "*.gz" -mtime 7 -type f -exec rm -f {} \;

logrotate_php_conf.erb

1. <%= php_log %>/*.log {
2. daily
3. rotate 7
4. missingok
5. dateext
6. notifempty
7. compress
8. sharedscripts
9. postrotate
10. [ ! -f <%= php_pid %> ] || /bin/kill -USR1 `/bin/cat <%= php_pid %>`
11. endscript
12. }

logrotate_php_sh.erb

1. #!/bin/bash
2. BACKUP_DIR=<%= backup_php %>         # php 日志备份目录
3. PHP_LOG_PATH=<%= php_log %>              # php 日志原始目录
4. LOGROTATE_CONF_DIR=`dirname $0`         # logrotate 配置文件目录，默认跟本脚本同目录
5. # 切割日志
6. /usr/sbin/logrotate -f $LOGROTATE_CONF_DIR/logrotate_php.conf
7. if [ ! -d $BACKUP_DIR ]; then
8. mkdir -p $BACKUP_DIR
9. fi
10. # 对切割完日志进行重定向压缩到 BACKUP_DIR
11. for log in `ls $PHP_LOG_PATH/*-20[1-9][0-9][0,1][0-9][0-3][0-9].gz`; do
12. mv $log $BACKUP_DIR/
13. done
14. # 删除7天前的备份日志
15. find $BACKUP_DIR/* -name "*.gz" -mtime 7 -type f -exec rm -f {} \;

由base.pp可知我们是需要backup_nginx,backup_php,base_cron这些参数的目录，这个我们可以直接用salt命令来实现
