错误：在 CentOS 7 (systemctl) 上安装 Varnish 4

Question

已从 yum 安装 Varnish；但通过 systemctl 启动时会立即出错。

SELinux 被禁用；软件包是通过 root 安装的。这是全新安装。

看来您需要重启。 ;)

留言：

Failed to read PID from file /var/run/varnish.pid Invalid argument

不重要。只是 systemd 试图过早阅读 pidfile。您可以通过以下方式轮询状态：

systemctl status varnish

如果它的 "Main PID" 条目与 /var/run/varnish.pid 的内容匹配（如果 varnishd 是通过 systemd 启动的，它总是如此），您可以忽略该消息。这在更高版本的 systemd 中已修复。
