关于squid启动错误

花花世界蕾

今天在玩squid 服务器时，发现一个问题很奇怪，因为前几天也是同样的默认配置，只更改了http_access deny all 这一项，然后启动一切正常，但是今天就奇怪了，始终启动不了，错误提示如下：

init_cache_dir /var/spool/squid... /etc/init.d/squid: line 62:  3586 已放弃               $SQUID -z -F -D >> /var/log/squid/squid.out 2>&1
启动 squid：/etc/init.d/squid: line 42:  3587 已放弃               $SQUID $SQUID_OPTS >> /var/log/squid/squid.out 2>&1


查看squid 服务器日志，内容如下：

发现是主机名有问题，hostname 查看主机名就是test7.*.gov.cn
发现一切OK，奇怪了，最后想了想莫非是我克隆系统的问题，因为这次克隆的这8个系统都是前天重新安装的，然后为了证实这个问题，用我以前的一个服务器上的linux 试了试，一切OK，没有任何问题，莫非真的有问题。

最后仔细检查，才发现我的/etc/hosts 中的记录竟然是这样，看完立马晕倒…………
我的主机名为：test7.*.gov.cn
# Do not remove the following line, or various programs
# that require network functionality will fail.
127.0.0.1               test1.*.gov.cn test1 localhost.localdomain localhost
::1             localhost6.localdomain6 localhost6


直接修改这个文件，为我的主机名之后，然后重新启动squid 代理服务器，一切OK，问题搞定…………


总结一点：克隆的系统方便是方便，但是有时出的问题真的搞不懂，很奇怪，克隆一定要克隆全部是默认参数的系统，然后根绝自己需要再进行适当的配置，比如IP地址、主机名等等。这样可以减少实验时莫名其妙的错误。
