squid 启动失败

本来打算源码包编译安装squid，但是编译时出错了。网上也没找到解决方法

只有暂时yum 安装squid，安装完后启动squid时报以下错误

[root@web squid]# service squid start
init_cache_dir /var/cache/squid... Starting squid: ........[FAILED]....

[root@web squid]# cat /var/log/squid/cache.log    #查看squid日志

通过错误信息发现可能是目录不存在，或者目录权限问题， 首先查看下目录  ls -l  /var/cache/squid
发现目录存在，但是目录下没有文件，使用squid -z 重新初始化

[root@web squid]# squid -z

[root@web squid]# ll -d /var/cache/squid/      ###查看下目录权限，发现目录所属用所属组是root
drwxr-xr-x 2 root root 4096 Feb 28 17:58 /var/cache/squid/




[root@web squid]# chown squid:squid !$       ### 更改目录所属主所属组为 squid
chown squid:squid /var/cache/squid/




[root@web squid]# squid -z                            ### 重新初始化
