squid -z来检查swap 目录FATAL: Failed to verify one of the swap directories, Check cache.log for details. Run ‘squid -z‘ to create swap directories if needed, or if running Squid for the first time. Squid Cache (Version 3.3.8): Terminated abnormally. CPU Usage: 0.016 seconds = 0.009 user + 0.007 sys Maximum Resident Size: 73008 KB Page faults with physical i/o: 0
squid -z发现是因为权限的问题，导致缓存文件无法写入whoami@blackman:~/script/AutoProxy-master/main/server$ /usr/sbin/squid3 -z whoami@blackman:~/script/AutoProxy-master/main/server$ 2018/01/24 11:26:12 kid1| Creating missing swap directories FATAL: Failed to make swap directory /var/cache/squid: (13) Permission denied 2018/01/24 11:26:15 kid1| Creating missing swap directories FATAL: Failed to make swap directory /var/cache/squid: (13) Permission denied
sudo chmod 777 /var/cache/squid/就解决了，这里由于是局域网服务器，直接就是777，简单粗暴些。whoami@blackman:~/script/AutoProxy-master/main/server$ sudo chmod 777 /var/cache/squid/ whoami@blackman:~/script/AutoProxy-master/main/server$ sudo /usr/sbin/squid3 -z whoami@blackman:~/script/AutoProxy-master/main/server$ 2018/01/24 11:29:42 kid1| Creating missing swap directories 2018/01/24 11:29:42 kid1| /var/cache/squid exists 2018/01/24 11:29:42 kid1| Making directories in /var/cache/squid/00 2018/01/24 11:29:42 kid1| Making directories in /var/cache/squid/01 2018/01/24 11:29:42 kid1| Making directories in /var/cache/squid/02 2018/01/24 11:29:42 kid1| Making directories in /var/cache/squid/03 2018/01/24 11:29:42 kid1| Making directories in /var/cache/squid/04 2018/01/24 11:29:42 kid1| Making directories in /var/cache/squid/05 2018/01/24 11:29:42 kid1| Making directories in /var/cache/squid/06 2018/01/24 11:29:42 kid1| Making directories in /var/cache/squid/07 2018/01/24 11:29:42 kid1| Making directories in /var/cache/squid/08 2018/01/24 11:29:42 kid1| Making directories in /var/cache/squid/09 2018/01/24 11:29:42 kid1| Making directories in /var/cache/squid/0A 2018/01/24 11:29:42 kid1| Making directories in /var/cache/squid/0B 2018/01/24 11:29:42 kid1| Making directories in /var/cache/squid/0C 2018/01/24 11:29:42 kid1| Making directories in /var/cache/squid/0D 2018/01/24 11:29:42 kid1| Making directories in /var/cache/squid/0E 2018/01/24 11:29:42 kid1| Making directories in /var/cache/squid/0F
到这里就解决了。squid -z创建完swap 目录后，会停在那，我等了几分钟，等不急了，直接ctrl+c给他结束了。然后service squid3 start就正常了。
