squid －z 没权限建立 swap directory ?

seayou_wey

安装的是suse10.1自带的 Squid Cache: Version 2.5.STABLE12

运行 squid -z 提示出错，但cache目录权限已经设置全权开放。

Squid的配置文件如下：在FC5中可以正确运行。


#squid.conf - a very basic config file for squid

chmod -R 777 /var/spool/cache

基本上 suse linux 有启用 AppArmor，也就是类似 RHEL 的 selinux 的功能。

suse 10.1 的 squid 预设 proxy 的目录不是 /var/spool/cache，而你自行改到其他位置，所以导致被 AppArmor 设定阻挡无法存取。再者预设身分一般也都用 squid/squid 就好，为何还要使用以前旧有的 nobody/nogroup 这类身分配置呢？

你要解决该问题的话，你的选择有:

1. 用 yast 跑一下 AppArmor 设定精灵，修改 squid 配置，或者是移除 squid 规则设定不监控等。

2. 关闭 AppArmor 功能 (不建议)。
