Ii. Install MYSQL_AUTH

# Gzip-d mysql_auth-0.6beta.tar.gz
# Tar vxf mysql_auth-0.6beta.tar
# Cd mysql_auth-0.6beta

The content to be modified in Makefile is as follows: // from www.w3sky.com

# Vi Makefile

CFLAGS =-I/opt/sfw/mysql/include-L/opt/sfw/mysql/lib/mysql
INSTALL =/usr/ucb/install
$ (INSTALL)-o root-g sys-m 700 mypasswd/usr/local/bin/mypasswd
$ (INSTALL)-o squid-g squid-MB 755 mysql_auth/usr/bin/mysql_auth
$ (INSTALL)-o squid-g squid-m 600 $ (CONF)/etc/mysql_auth.conf
$ (INSTALL)-o squid-g squid-m 600 $ (CONF)/etc/mysql_auth.conf.default

The content to be modified in src/define. h is as follows:

# Vi + 5 src/define. h
# Define CONFIG_FILE '/etc/mysql_auth.conf'
# Define DEF_MYSQLD_SOCKET '/tmp/mysql. sock'

The following content needs to be modified in src/mysql_auth.conf:

# Vi src/mysql_auth.conf
Mysqld_socket/tmp/mysql. sock
#/Usr/ccs/bin/make
#/Usr/ccs/bin/make install
Create a user database:
# Cd scripts
# Mysql-u root-p ****** <create_script

Test MYSQL_AUTH

1. Add a test user
# Mypasswd llzqq 123456
Password record ADDED succesfully.

2. Verify the created user
# Mysql_auth
Llzqq: 123456

3. delete an existing user and use this command.
# Mypasswd-d username

3. Add the MYSQL_AUTH authentication section in SQUID. CONF.

# Vi/etc/squid. conf

Add the following code to the end of the "TAG: acl" section in SQUID. CONF.

Auth_param basic program/usr/bin/mysql_auth
Auth_param basic realm LLZQQ's CACHING SERVER
Auth_param basic children 5
Auth_param basic credentialsttl 2 hours
Acl password proxy_auth REQUIRED
Http_access allow password
Authenticate_ip_ttl 2 hours
