Squid cache

Proxy servers cache on local hard disks to improve network efficiency

1 Modify squid configuration file "/etc/squid/squid.conf", parameter "cache_dir_ufs" is to set cache directory

[root@localhost wj]# gedit /etc/squid/squid.conf

# Uncomment and adjust the following to add a disk cache directory.

cache_dir ufs /var/spool/squid 100 16 256 //cache directory var/spool/squid, size 100M

2. Restart squid service

[root@localhost wj]# service squid start

Starting squid: . [OK]

[root@localhost wj]# gedit /etc/squid/squid.conf

[root@localhost wj]# service squid restart

Stop squid: 2018/08/15 11:17:31| WARNING cache_mem is larger than total disk cache space!

................ [OK]

init_cache_dir /var/spool/squid... Starting squid: . [OK]

[root@localhost wj]#

3. Check the squid cache directory, where swap.state will gradually increase with the number of web pages visited.

[root@localhost wj]# ls -al /var/spool/squid/

Total consumption 76

-rw-r---- 1 squid squid 52 August 15 11:18 swap.state

[root@localhost wj]#

4. Clean up the cache regularly

Swap.state grows larger in the squid cache directory and the user needs to clear the file periodically, or do a scheduled task to clear it.
