logrotate 不分割日志文件

logrotate 不分割日志文件

我正在尝试让 logrotate 在我的 OpenResty 服务器日志上工作。我的 logrotate 配置文件/etc/logrotate.d/openresty应该每天执行，这是默认行为，我正在尝试使用sudo logrotate -vfd /etc/logrotate.d/openresty.

这就是我的配置方式：

/home/appname/logs/openresty/*.log /var/log/openresty/*.log {
        su root root
        size 100M
        missingok
        rotate 14
        compress
        delaycompress
        notifempty
        create 0660 root root
        sharedscripts
        prerotate
        if [ -d /etc/logrotate.d/httpd-prerotate ]; then \
                run-parts /etc/logrotate.d/httpd-prerotate; \
        fi \
        endscript
}

但这就是我的日志目录 ( ~/logs/openresty) 的样子：

total 1.3G
-rw-r----- 1 root     root 1.2G Jul 23 09:41 access.log.1
-rw-r----- 1 www-data adm  154K Jul 13 11:43 access.log.2.gz
-rw-r----- 1 www-data adm  159M Jul 13 11:18 access.log.3.gz
-rw-r----- 1 root     root 572K Oct  5 04:24 error.log
-rw-r----- 1 root     root  62K Jul 23 02:52 error.log.1
-rw-r----- 1 www-data adm   12K Jul 13 10:55 error.log.2.gz

正如您所看到的，主日志文件远高于 100 MB 的限制，并且它没有按应有的方式进行分割。也不知道为什么它被命名access.log.1而不是access.log（这是它在服务器中的配置方式）。

当我运行时，sudo logrotate -v /etc/logrotate.d/openresty我得到以下输出：

然而，绝对没有任何东西会旋转~/logs/openresty。它只是忽略了整个事情。

并且创建了/var/log/openresty一个新的空日志access.log，但旧的日志没有被分割，并且仍然超过 100 MB：

total 379M
-rw-rw---- 1 root     root    0 Oct  5 08:51 access.log
-rw-r----- 1 root     root 366M Oct  5 08:53 access.log.1
-rw-r----- 1 root     root 5.1M Jul 23 09:41 access.log.2.gz
-rw-r----- 1 www-data adm  8.0K Jul 13 11:42 access.log.3.gz
-rw-r----- 1 root     root 8.2M Jul 13 11:18 access.log.4.gz
-rw-r----- 1 www-data adm   70K Oct  4 14:17 error.log
-rw-r----- 1 root     root  948 Jun 26 10:24 error.log.1

此外，由于某种原因，服务器继续写入access.log.1而不是access.log.

答案1

Logrotate 正在工作，但 openresty 不知道它应该写入新的日志文件（因此它不断写入access.log.1）。

您需要将postrotate脚本添加到您的配置中：

postrotate
  /usr/local/bin/openresty -s reload
endscript

（我不熟悉 openresty，所以这openresty -s reload只是一个猜测 - 你需要在你的文档中查找它）
