Squid 缓存未在 Ubuntu 16.04.2 LTS 中启动

我正在尝试通过以下命令启动 Squid (3.5.12)：

$ /etc/init.d/squid start

[ ok ] Starting squid (via systemctl): squid.service.

但 中只出现了一行cache.log，没有其他内容：

2017/03/23 18:44:40| Set Current Directory to /var/spool/squid/cache

我确实跑了squid -z。

我的squid.conf样子如下图：

答案1

当前的 Ubuntu LTS（16.04）系统服务最好通过 systemd 进行管理，这意味着在您的情况下，要启动、检查状态、停止 squid，您将（分别）使用：

# systemctl start squid
# systemctl status squid
# systemctl stop squid

为了向后兼容 System V，service 命令仍然受支持，但将来可能会消失。通过直接调用来运行服务

# /etc/init.d/servicename

不支持/推荐。

答案2

解决方案是不使用/etc/init.d/squid start。

service squid restart工作正常。

不知道为什么017/03/23 18:44:40| Set Current Directory to /var/spool/squid/cache日志中会出现第 2 行。
