Squid is a caching and forwarding web proxy. It is most often used in conjunction with a traditional LAMP stack (Linux, Apache, MySQL, PHP), and can be used to filter traffic on HTTP, FTP, and HTTPS, and increase the speed (thus lower the response time) for a web server via caching.
These instructions are intended specifically for installing Squid on a single CentOS 7 node.
I’ll be working from a Liquid Web Core Managed CentOS 7 server, and I’ll be logged in as root.
Step #1 Install Squid
First, clean-up yum:
yum clean all
As a matter of best practice we’ll update our packages:
yum -y update
Installing Squid and related packages is now as simple as running just one command:
yum -y install squid
Configure Squid to Start on Boot
And then start Squid:
systemctl start squid
Be sure that Squid starts at boot:
systemctl enable squid
To check the status of Squid:
systemctl status squid
To stop Squid:
systemctl stop squid
To access squid settings access : /etc/squid/squid.com
My basic config:
http_access allow localhost manager http_access deny manager # We strongly recommend the following be uncommented to protect innocent # web applications running on the proxy server who think the only # one who can access services on "localhost" is a local user #http_access deny to_localhost # # INSERT YOUR OWN RULE(S) HERE TO ALLOW ACCESS FROM YOUR CLIENTS # # Example rule allowing access from your local networks. # Adapt localnet in the ACL section to list your (internal) IP networks # from where browsing should be allowed http_access allow localnet http_access allow localhost # And finally deny all other access to this proxy http_access deny all # Squid normally listens to port 3128 http_port 3128 # Uncomment and adjust the following to add a disk cache directory. #cache_dir ufs /var/spool/squid 10000 16 256 cache_replacement_policy heap LFUDA cache_swap_low 90 cache_swap_high 95 maximum_object_size_in_memory 100 MB cache_dir aufs /var/spool/squid 40000 16 256 cache_mem 40000 MB # Leave coredumps in the first cache dir coredump_dir /var/spool/squid # # Add any of your own refresh_pattern entries above these. #
That is all!
I used to be suggested this web site by my cousin. I’m no
longer sure whether or not this publish is written via him as nobody else know such designated about my
problem. You’re amazing! Thank you!
