?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(shí)現(xiàn)nginx+php 用logrotate來(lái)對(duì)日志進(jìn)行切割，然后再簡(jiǎn)單的使用下salt這個(gè)工具；

架構(gòu)如下:

?

以下.pp文件均在/etc/puppet/modules/logrotate/manifests下面，內(nèi)容如下

init.pp

由base.pp可知我們是需要backup_nginx,backup_php,base_cron這些參數(shù)的目錄，這個(gè)我們可以直接用salt命令來(lái)實(shí)現(xiàn)

?

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'? 下篇待續(xù)
