线上运维过程中切日志用了logrotate,但无奈日志打的太多,一天的日志几十G难以分析,遂决定改成每小时切分一次日志。从logrotate的说明看有hourly的支持,但是直接把daily改成hourly之后启动报错:

unknown option 'hourly'

感觉是logrotate 3.8.7的版本不支持hourly语法

rpm安装logrotate高版本的包提示缺少fillup和其他的依赖,同时glibc的版本也要求高版本。于是下载了logrotate的源码安装,以最新版本3.9.2为例

./autogen.sh
./configure

提示缺少libpopt头文件,下载了libpopt 1.5的源码安装,提示libtool版本不对。我擦嘞。

后来突然想到libpopt是debian下的命名,试一下centos下

yum install popt-devel -y

搞定。于是继续源码安装,直接用logrotate的官网版本好了。

yum install popt-devel -y
wget https://fedorahosted.org/releases/l/o/logrotate/logrotate-3.8.6.tar.gz
tar zxvf  logrotate-3.8.6.tar.gz
cd logrotate-3.8.6 && make && make install

这个版本是可以稳定使用的。中间试了几个别的版本,3.8.3还是不支持hourly语法,3.8.5支持了语法,但是测试的时候

logrotate -d /etc/logrotate.conf

有core,跟进源码去感觉是依赖bug,换到3.8.6终于ok了…回去看作者更新日志:

3.8.4 -> 3.8.5
     - Improved rotation during daylight saving time and between timezone
       changes.
     - Fixed ACL setting problem caused by ext3 erroneously reporting ENOSYS
       instead of ENOSUP.
     - Do not continue with rotation if state file is corrupted.
     - Make logrotate.status creation atomic.
     - Allow "hourly" rotation. See manpage for more information.
     - Use "/bin/echo" in tests. Fixes tests execution in Dash.
     - Do no try to parse config files bigger than 16MB.
     - Improved manpage consistency and formatting.
     - Fix race condition between acl_set_fd() and fchmod().
