New password:

Re-type new password:

Adding password for user david

2. Modify the authentication file so that other users can read it.

[root@localhost wj] # chmod ostatr / etc/squid/passwd

3. View certification service documents

[root@localhost wj] # rpm-ql squid | grep ncsa_auth

/ usr/lib/squid/ncsa_auth / / remember this address, which will be used below

/ usr/share/man/man8/ncsa_auth.8.gz

4. Modify the configuration file squid.conf

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

Auth_param basic program / usr/lib/squid/ncsa_auth / etc/squid/passwd / / account location, password location
