实战:logrotate 日志轮转及配置

1,编写系统日志的配置文件 /etc/rsyslog.conf

2,写入配置

[root@A logrotate.d]# cat /etc/rsyslog.conf

# rsyslog v5 configuration file

*.* /var/log/admin.log(所有的服务,所有级别的日志全部写入到此路径下面)

3,重启rsyslog服务,检查并且查看是否有日志生成

[root@A logrotate.d]# ll /var/log/admin.log

-rw-------. 1 root root 0 Sep 4 01:38 /var/log/admin.log

[root@A logrotate.d]# /etc/init.d/rsyslog restart

4,查看日志轮转配置文件。以及相关的格式

[root@A logrotate.d]# cat /etc/logrotate.conf

# see "man logrotate" for details

# rotate log files weekly

weekly

# keep 4 weeks worth of backlogs

rotate 4

# create new (empty) log files after rotating old ones

create

# use date as a suffix of the rotated file

dateext

# uncomment this if you want your log files compressed

#compress

# RPM packages drop log rotation information into this directory

include /etc/logrotate.d (调用子配置文件,通常把日志的策略放在此路径下,方便管理)

5,在/etc/logrorate.d 路径下为系统日志/var/log/admin.log 创建策略

vim /etc/logrorate.d/admin

[root@A logrotate.d]# cat admin

/var/log/admin.log {

daily 每天轮转

rotate 3 保留3个备份

minsize 100k 大小至少100k才开始轮转

missingok 丢失不提示

compress 压缩文件

create 0600 root root 建新文件并设权

dateext 日志文件以日期命名

}

6,可以强制检测,轮转策略是否生效

logrotate -f /etc/logrorate.d/admin

[root@A logrotate.d]# ll /var/log/admin*

-rw-------. 1 root root 0 Sep 4 01:38 /var/log/admin.log

-rw-------. 1 root root 469 Sep 4 01:38 /var/log/admin.log.1

-rw-------. 1 root root 187 Sep 4 01:38 /var/log/admin.log-20170904.gz
