如何在 logrotate.conf 中重启服务

Question

我有一个生成登录的脚本 /var/log/venaqua。我想使用 logrotate 管理该日志。为此，我在 /etc/logrotate.d/venaqua 文件

中添加了以下代码

/var/log/venaqua{
    daily
    prerotate
        /bin/echo "`date` Starting Logrotate" >> /log/var/venaqua
    endscript
    rotate 5
    compress
    minsize 1M
    create 0644 root root
    postrotate
        /bin/systemctl restart venaqua.service
        /bin/echo "`date` Logrotate Completed" >> /log/var/venaqua
    endscript
}

我正在测试

sudo logrotate -v -f /etc/logrotate.conf

我收到错误消息

Answer 1

cannot create /log/var/venaqua: Directory nonexistent 说明了一切。您已在初始日志定义 /var/log/venaqua{ 和预旋转脚本中的后续路径 >> /log/var/venaqua 之间切换了 /var/log/ 和 /log/var。此错误也存在于您的旋转后脚本中。
