logrotate日志轮替
logrotate日志切割:
1.防止日志文件过大2.定期删除旧日志文件配置文件:rpm -qc logrotate 文件如下/etc/cron.daily/logrotate/etc/logrotate.conf/etc/rwtab.d/logrotate/var/lib/logrotate/logrotate.status查轮滚策略帮助手册:man logrotate.conf配置文件内容:cat /etc/logrotate.conf注:此配置文件主要定义日志文件切割(轮滚、轮转、滚动)的策略方案.# see "man logrotate" for details# rotate log files weeklyweekly 每周一轮滚# keep 4 weeks worth of backlogsrotate 4 保留4个备份# create new (empty) log files after rotating old onescreate 创建新的空日志文件代替旧文件# use date as a suffix of the rotated filedateext 使用日志为文件名后缀,禁用此项时默认以数字为后缀.# uncomment this if you want your log files compressed#compress 是否压缩(后缀为.gz)# RPM packages drop log rotation information into this directoryinclude /etc/logrotate.d 包含指定的目录,此目录下保存日志策略# no packages own wtmp and btmp -- we'll rotate them here/var/log/wtmp { 日志文件路径及其个性化轮转策略 monthly 每月一轮滚 create 0664 root utmp 创建的新日志文件权限、属主 、属组 minsize 1M 文件最小容量 rotate 1 保留1个备份}/var/log/btmp { missingok 丢了也OK,即不会报错 monthly create 0600 root utmp rotate 1}# system-specific logs may be also be configured here.-----------------强制测试轮滚: logrotate -fv /etc/logrotate.conf ; ls /var/log/注:1.-f是强制轮滚,-v显示过程 2.日志文件名后缀的数字越大,文件越旧.日志清理时是清理旧文件.练习:给/var/log/my.log日志文件创建轮滚策略,每天一轮滚,文件丢了也不报错,保留2个备份,启用压缩功能,用数字作为文件名后缀.
vim /etc/logrotate.d/my 添加如下内容/var/log/my.log { daily 每天一轮滚missingok 丢了也不报错nodateext 不使用日期为后缀,即用数字为后缀create 创建新文件rotate 2 保留2个备份compress 启用压缩(后缀为.gz)}测试轮滚: logrotate -fv /etc/logrotate.d/my ;查看日志文件列表: ls /var/log/my*
